In slope-intercept form, what is the equation of the line containing the points (−1, 2) and (2, −1)?

Answers

Answer 1

Answer:

y=-x+1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-2)/(2-(-1))

m=-3/(2+1)

m=-3/3

m=-1

y-y1=m(x-x1)

y-2=-1(x-(-1))

y-2=-(x+1)

y=-x-1+2

y=-x+1

Joel borrowed $1,512. He was to pay that amount back along with an additional 9% interest. He could only pay back 82% of what he should have. How much did Joel pay back on his loan?

Answers

Answer:

$1351.43

Step-by-step explanation:

The amount to pay:

$1512 + 9% = $1512*1.09 = $1648.08

The amount paid back:

82% of $1648.08 = 0.82*1648.08 = $1351.43

(50pts) The distance covered and the time taken by a car are plotted in a graph.


a. Find the slope of the line in the graph.
b. Calculate the distance traveled by the car at the 20th second.
c. Calculate the speed of the car.

Answers

Answer:

a=2

b=40m

c=2m/s

Step-by-step explanation:

slope is rise over run so 10/5 simplified is 2/1 or 2

for b just look at the graph at the 20th second

for c you do distance over time so basically the same thing as a 10/5 which is 2m/s

(3 x)/(5 x + 2)

Step-by-step explanation:

Simplify the following:

(3 x^2)/(5 x^2 + 2 x)

Hint: | Factor common terms out of 5 x^2 + 2 x.

Factor x out of 5 x^2 + 2 x:

(3 x^2)/(x (5 x + 2))

Hint: | For all exponents, a^n a^m = a^(n + m). Apply this to (3 x^2)/(x (5 x + 2)).

Combine powers. (3 x^2)/(x (5 x + 2)) = (3 x^(2 - 1))/(5 x + 2):

I believe you would do 10/3x+1=22/7x-1 and cross multiply meaning multiply 10 by 7x-1 and 22 by 3x+1 and since you can’t really do this you need to make them into an equation. 10(7x-1)=22(3x+1) and distribute leaving you with 70x-10=66x+22 so you minus 66 from both sides leaving you with 4x-10=22 so you add 10 on both sides making it 4x=32 so you divide both sides by 4 leaving you with the answer X=8.

What is a number line?

A number line is a pictorial representation of lines on a calibrated straight line that serves as a basis for expressing real numbers on a straight line.

We should equally note that:

The left-hand side is the negative x-axis and,The right-hand side is the positive x-axis.

From the given figures;

Point A lies to the negative axis direction on point scale 4 i.e -4Point D lies extremely to another point scale so we can say it is [tex]\mathbf{1 \dfrac{3}{4}}[/tex]Since 3/4 is roughly 0.75 = 1 + 0.75 = 1.75

Therefore, we can conclude that Point A represents -4, Point D represents  [tex]\mathbf{1 \dfrac{3}{4}}[/tex] and  [tex]\mathbf{1 \dfrac{3}{4}}[/tex] > -4.

x6 + 4x3 + 10x7

Answers

Answer:

A. −3x⁵ + 4x³ + 10x²

Step-by-step explanation:

The standard form means that the terms are ordered from biggest exponent to lowest exponent.

Verify the answer options

A. −3x⁵ + 4x³ + 10x²

5, 3, 2 - correct order

C. x⁴ + 4x³ + 10x⁴

4, 3, 4 - incorrect order

D. x⁶ + 4x³ + 10x⁷

6, 3, 7 - incorrect order

Answer:

[tex] { - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]

Step-by-step explanation:

For a polynomial to be in standard form, it must satify the conditions below:

1) It must not contain like terms

2) The exponents (powers) must be written in descending order

That is, the polynomial must be of the form

[tex]f(x) = {ax}^{n} + {bx}^{n - 1} + {cx}^{n - 2} + . \: . \: . \: . \: . \: mx + n[/tex]

Where a, b, c, m, n, are coefficients/constants

The only option that satifies the above conditions, and follows the pattern f(x) shown is:

[tex]{ - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]

National statistics show that 23% of men smoke and 18.5% of women smoke. A random sample of 175 men indicated that 45 were smokers, and a random sample of 155 women surveyed indicated that 42 smoked. Construct a 98% confidence interval for the true difference in proportions of male and female smokers.

Answers

Answer:

98% C.I. = [-0.1270, 0.0994]

Step-by-step explanation:

Here

p1= proportion of men smokers

p1= 45/175= 0.2571

p2= proportion of women smokers

p2= 42/155= 0.2709

1)  Choose the significance level ∝= 0.02

2) The formula for confidence interval is

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

and

(p1^- p2^) z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

3)  The z value is 2.05

4) Calculations:

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(-2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=-0.1270 ( using calculator)

And

(p1^- p2^)z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=0.0994  ( using calculator)

and Putting ± 2.05 in the confidence interval formula we get limits (-0.1270, 0.0994)

What is the value of x

Answers

Answer:

x = 9

y = 5

Step-by-step explanation:

<N and < M are opposite equal sides. So they are equal as well. In addition, the base is equal to the other 2 sides. That means you are dealing with an equilateral triangle. All the angles are equal to 60 degrees.

7x - 3 = 60 degrees     Add 3 to both sides

      3      3

7x = 63                         Divide by 7

x = 63/7

x = 9

Just for the sake of completeness, we'll find y

11y + 5 = 60                 Subtract 5 from both sides

     -5      -5

11y = 55                       Divide by 11

y = 55 /11

y = 5

If you are taking a test at 8:30 am and it takes you 2 1/2 hours what time would it be? PLEASE ANSWER

Answers

Answer:

11:00

Step-by-step explanation:

This is easier than I thought...

So 8:30+2 is 10:30

...and now we have 1/2 left.

1/2 in this case of time would be 30

So, 10+30+30 would be 10:60

Now all we have to do is simplify it

60 minutes= 1 hour

So...

10:60-60=10

10+1=11

Four rays meet at a common endpoint. Find the value of x. Find the measurement of angle CAD, if angle BAC =60, DAE= 90 and angle BAE= 12x, CAD=3x

Answers

Answer:

x = 14

<CAD = 42degrees

Step-by-step explanation:

Since all the rays meet at a point, the sum of all the angles at the point will be 360 degrees, since angle at a point is 360degrees

Taking the sum of all the angles and equating to 360, we will have;

<BAC + <DAE + <BAE + <CAD = 360

60+90+12x+3x = 360

150 + 15x = 360

15x = 360 - 150

15x = 210

x = 210//15

x = 14

Get <CAD

Since <CAD = 3x

<CAD = 3(14)

<CAD = 42 degrees

Hence the measure of angle CAD is 42degrees
