The daytime temperature in Montana yesterday was -4.5 degrees, and it was expected to drop 6.5 more degrees today. What is today’s expected daytime temperature?

Answers

Answer 1

-11 degrees is the expected daytime temperature for today

The daytime temperature yesterday in Montana = -4.5 degrees

Expected temperature drop today = 6.5 degrees

The term "temperature" describes how hot or cold the atmosphere is and is measured with a thermometer. Temperature is reported by meteorologists in both Celsius (C) and Fahrenheit (F).

Today's expected daytime temperature:

The daytime temperature yesterday in Montana + Expected temperature drop today

But since the temperature of yesterday is negative we will use a negative sign to add the expected temperature of today. A drop in temperature will lead to a more cold temperature

= -4.5 + (-6.5)

= -11 degrees

write an equation in slope intercept form for a horizontal line through (15,21)

Answers

Slope-intercept form is y = 21.

What is a equation of line?

The equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y -intercept (the point in which the line crosses the y -axis).

Given that,

The line is horizontal. It means slope of this line is zero. We can use the point-slope form for a linear equation since we know the slope and the point (15, 21).

Point-slope form: [tex](y-y_{1}) = m(x-x_{1})[/tex]

Where,

m = slope and [tex](x_{1}, y_{1})[/tex] is the points.

Then,

[tex](y-y_{1}) = m(x-x_{1})[/tex]

[tex](y-21) = 0(x-15)[/tex]

[tex]y-21 = 0\\y=21[/tex]

Hence, the Slope-intercept form is y = 21.

Step-by-step explanation:

Add AC and BC together to get AB.

AC = 2x - 13 and

BC = 3x + 4 and

AB = 36 (this is all the given information)

The two smaller pieces can be combined to equal the whole segment.

AC + BC = AB

2x - 13 + 3x + 4 = 36

combine like terms.

5x - 9 = 36

Add 9

5x = 45

Divide by 5.

x = 9

BC = 3x + 4

substitute 9 for x.

BC = 3(9) + 4

if you placed $5 into an account that paid interest at a rate of 5%, and compounded interest yearly, how much would that account be worth in 100 years

Answers

After adding interest the sum would be worth $657.51 .

Interest is the amount paid over and above the original amount to a lender or depositor by a borrower or deposit-taking financial institution at a predetermined rate in the domains of finance and economics (the amount borrowed).

Interest differs from any fees the borrower may be required to pay to the lender or another party.interest also contrasts from a dividend, which is cash distributed to shareholders (owners) by a corporation from its profit or reserve, but not at a predefined rate or proportionally; rather, it is a portion of the reward or interest gained by risk-taking businessmen when revenue is made that surpasses all expenditures.

Interest when the principal is $5 , time is 100 years and rate is 5%.

We know that from compound interest:

Amount = principal (1 + rate)ⁿ

Therefore

Amount = 5 (1 +0.05)¹⁰⁰

Amount = $657.5062...

Amount ≈ $657.51

Therefore adding interest the sum would be worth $657.51

We have a line segment.(a) Suppose we have another line parallel to the given line segment. If we take the reflection of the line segment over the line, it will result in a parallel line segment only.(b) Suppose we have an arbitrary point which is not on the line segment. We rotate the line segment by an angle of 90° about the point. This will change the direction of the line segment.(c) If we translate the line segment in a direction perpendicular to the line segment, it will just change its position, but it will still remain parallel.(d) Suppose we have an arbitrary point which is not on the line segment.

Answers

The greatest common divisor (24,6) is 6 and the least common multiple (24,6) is 24.

As per the question statement, the greatest common divisor of two integers is (x+2) and the least common multiple x(x+2). It is given that one of the integers is 24.

Let us assume that "b" is the value of other one.

greatest common divisor(24,b) = (x+2)

least common multiple(24,b) = x(x+2)

Formula:

greatest common divisor(24,b)*least common multiple(24,b) = 24*b

24*b = (x+2)*x(x+2)

[tex]b = \frac{x(x+2)^{2} }{24} \\[/tex]

Hence, the smallest possible value of the other one is "6" and x = 4.

Answers

Based on the median and the centroid theorem, the length of WI is 6 units.

What is the Median of a Triangle?

The line that joins the vertex of a triangle to the midpoint of the side it is directly opposite is called the median of a triangle.

According to the centroid theorem, since J is the centroid of triangle XYW, then:

the length of IE is 1/3 of the length of segment EW.

Thus, the equation that relates the length of the segments is;

IE = 1/3(EW)

Given that:

IE = 3 units

Now Substitute the value of IE into the equation:

3 = 1/3(EW)

3(3) = EW

9 = EW

EW = 9 units

Therefore:

The Length of WI = the length of EW - the length of IE

Substitute;

Length of WI = 9 - 3

The value of y is directly proportional to the value of x. When x=3.5, the value of y is 14. What is the value of y when x = 28? Record your answer

Answers

For x = 28, the value of [y] such that [x] is directly proportional to [y] will be 112.

What is direct proportionality?

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. Mathematically, direct proportionality is represented by a straight line and it equation is of the form -

y = kx

k = y/x

where [k] is the constant

Given is the value of [y], which is directly proportional to the value of [x], and when [x] = 3.5, the value of [y] is 14.

We have the following data -

[y] = 14 at [x] = 3.5

Now, since [y] is directly proportional to [x], we cam write -

y = kx

k = y/x

k = 14/3.5.            [1]

Now, for x = 28, we can write the relation as -

y/x = k

k = y/28            [2]

Now, equating equation [1] and [2], we get -

14/3.5 = y/28

y = (14 x 28)/3.5

y = (140 x 28)/35

y = (140 x 4)/5

y = 28 x 4

y = 112

Therefore, for x = 28, the value of [y] such that [x] is directly proportional to [y] will be 112.

can someone pls explain to me how to find y intercept

Answers

Answer:

(0, -5)

Explanation:

The function is represented by f(x), and the line graphed would be y= f(x). In slope-intercept form, the equation of a line is given by y= mx +c, where m is the slope and c is the y-intercept.

Since we know that the line is linear, any two points along the line would give us the same slope value. Since y-intercepts occur at x= 0, let the y-intercept be (0, y).

[tex]\boxed{ \text{slope} = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

Slope between (-3, 1) and (1, -7)= slope between (-3, 1) and (0, y)

[tex] \frac{1 - ( -7 )}{ - 3 - 1} = \frac{y - 1}{0 - ( - 3)} [/tex]

[tex] \frac{1 + 7}{ - 4} = \frac{y - 1}{0 + 3} [/tex]

[tex] \frac{8}{ - 4} = \frac{y - 1}{3} [/tex]

[tex] - 2 = \frac{y - 1}{3} [/tex]

Multiply both sides by 3:

-2(3)= y- 1

-6= y -1

Add 1 to both sides:

y= -6 +1

y= -5

Thus, the y-intercept is (0, -5).

__________

Based on the image, however, we are to find the equation of the linear function in slope-intercept form.

The first step would be to find the slope between any two points, which would be -2. This is found using the slope formula, and we have calculated it above.

Substitute the value of the slope into y= mx +c:

y= -2x +c

The y-intercept can be found by substituting a pair of coordinates the line passes through.

When x= -3, y= 1,

1= -2(-3) +c

1= 6 +c

c= 1 -6

c= 5

Thus, the equation of the line is y= -2x +5.

Answer:

y = - 2x - 5

The intercept is 5 because that is where the graph cuts the y axis.

PLEASE MARK AS BRAINLIEST IF YOU FOUND IT HELPFUL BECAUSE IT MAKES ME FEEL GOOD!

Step-by-step explanation:

Linear Standard Form

y = mx + c;

The m equals the change in y divided by the change in x. If you choose left to right for y then you must do the same for x as well.

Δy = ( - 7 ) - ( - 15 ); Δx = 1 - 5;

Δy = - 7 + 15;

Δy = 8;

Δx = - 4;

m = 8 / - 4;

m = - 2;

y = - 2x + c;

Point Substitution

Pick a point (x, y) and sub it into the equation. Make sure to use brackets when subbing.

- 7 = - 2( 1 ) + c;

- 7 = - 2 + c;

Add 2 to both sides.

- 7 + 2 = - 2 + 2 + c;

- 5 = c;

c = - 5;

The c is the intercept.

y = - 2x - 5

Which of the following equations shows how substitution can be used to solve the following system of equations?

Answers

By substituting the first equation into the second, we get:

2x + 5*(2x +3) = 3

The correct option is the second one.

Which equation shows how substitution?

Here we have the system of equations:

y = 2x + 3

2x + 5y = 3

You can see that the variable "y" is already isolated in the first equation, so we can just substitute it in the second equation:

2x + 5*(2x +3) = 3

This is what we can see in the second option, so we conclude that the second option is the correct one.

Segment AC = 6 and segment A'C' =4

They just subtracted two from the 6

Let's do the same thing for segment BC!

If BC = 3, then we know that B'C' = 1
