What is the equation of the line that passes through the point (-5, 7) and has a slope of -2/5?​

Answers

Answer 1

Answer:

I hope that it will be help full for u

Step-by-step explanation:

As we know the equation of line is ,

y= mx+ c

As given

slope=m=-2/5

also given (x, y)= (-5, 7)

we get   x=-5  , y=7

putt in the equation of line all these values we get ,

7=(-2/5)(-5) +c

c=7-2

c=5   now putt the value of c and m  in equation of line we will get ,required equation of line

y = (-2/5)x + 5  Ans

Answer 2

Using slope intercept form, the equation of the line that passes through the point (-5,7) and has a slope of -2/5 is y = - 2/5x + 5.

What is slope intercept form?

The equation of the "straight line is in the form y = mx + b where 'm' is the slope of the line, 'b' is the y - intercept form" is called slope intercept form.

According to the question,

The line passes through the point (-5,7) and has slope of -2/5,

The equation of the straight line y = m x + c. Substitute (-5,7) and slope -2/5 in general equation we have 7 = -2/5 (-5) + c

7 = 2 + c

c = 7-2

c = 5

Hence, using slope intercept form, the equation of the line that passes through the point (-5,7) and has a slope of -2/5 is y = - 2/5x + 5.

Nancy has to mark the point with the coordinates (-2, 4) on the coordinate plane. Which point in the graph is at (-2, 4)? In which quadrant is the point located?​

Answers

The quadrant that (-2,4) is quadrant 2 hopes this helps u

Answer:

Point A at Quadrant 2

Step-by-step explanation:

For point (-2, 4) the -2 is the x-axis and the 4 is the y-axis. All points at -2 on the x-axis are A, J, and K. All points at 4 on the y-axis are A, B, and C. Since point A is satisfies both of the places on the x-axis and the y-axis, your answer is point A.

HURRY!!!! A summer camp is providing breakfast for 350 children that includes a 6 ounce serving of sausage per student. The camp can only purchase sausage in whole 1 pound packages. Note: 1 pound = 16 ounces? PLEASE I NEED HELP

Answers

Answer:

132 whole 1 pound packages.

Step-by-step explanation:

6 ounces times 350* equals 2100 ounces, so the summer cap needs 2100 ounces of sausage to feed all 350 children. We already know there are 16 ounces per pound. 16 x 131 equals 2096. Remember, it takes 2100 ounces to feed all 350 children. The summer camp will have to buy 132 packages to exceed 2100 without having additional whole packages.

*this number represents the amount of children

The camp needs to buy 132 packets of sausage to serve 350 students.

What is a unitary method?

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, A summer camp is providing breakfast for 350 children that include a 6-ounce serving of sausage per student.

So, The total amount of sausages is,

= 6×350 ounces.

= 2100 ounces.

Also given, sausages come in 1 pound pack.

Therefore, The number of packets required is,

= (2100/16).

= 131.25 but they have to buy 132 packets.

(0,0) (-4,-4) (2,-4) graph the image of this triangle after a dilation with a scale factor of 2 centered at the origin​

Answers

Answer:

The image coordinates are:

A'(0, 0)

B'(-8, -8)

C'(4, -8)

The graph of the image coordinates attached below.

The image triangle A'B'C' is illustrated in green color.

Step-by-step explanation:

Let the points of a triangle be

A(0,0) B(-4,-4) C(2,-4)

We need to determine the graph of the image of this triangle after a dilation with a scale factor of 2 centered at the origin.

As scale factor > 0, thus the image will be enlarged.

A dilation by a scale factor of 2 centered at the origin means the coordinates of the image can be obtained by multiplying the original coordinates with 2.

Next, the rule of dilation by a scale factor of 2 is given by

Dilation: (x, y)  →  (2x, 2y), centered at (0, 0)

P(x, y)  → P' (2x, 2y)

A(0, 0) → A' (2(0), 2(0)) → A'(0, 0)

B(-4, -4) → B' (2(-4), 2(-4)) → B'(-8, -8)

C(2,-4) → C' (2(2), 2(-4)) → C'(4, -8)

Therefore, the image coordinates are:

A'(0, 0)B'(-8, -8)C'(4, -8)

The graph of the image coordinates attached below.

The image triangle A'B'C' is illustrated in green color.

B: 45+63= 9*(5+7)

Step-by-step explanation:

Answer:

b is 45+63=9(5+7)

Step-by-step explanation:

Once you know the GCF, you just need to find what the GCF (9 in this case), times what will get you 45 and 63. So we already know that 9 will be on the outside of the parentheses since it's what we're multiplying by. 9 times 5 is 45, so for the first number in the parentheses you'll put 5, and for the second, 9 times 7 is 63, so the second number in the parentheses is 7. You can check by solving it. 9(5+7). Use the distributive property and first you will do 9 times 5, which is 45, then 9 times 7 which is 63, so you'll get 45+63, which is correct.

The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was $1,500? If you get stuck, consider using diagrams or a table to organize your work.

Answers

Answer:

After one year, the car will be worth $1,275.

Step-by-step explanation:

We know that a new car value decreases by 15% every year. So, we first need to find 15% of $1,500.

1,500 x 0.15 = $225.

Now, me must subtract $225 from the initial value, or $1,500.

1,500 - 225 = $1,275

Therefore, after one year, the car will be worth $1,275.

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The equation is y=3/2x - 6

y equal to three by two times of x minus six

y=3/2x - 6

LCM of 1 and 2 is 2

y=(3x-12)/2

Now apply cross multiplication

2y=3x-12

Two times of y equal to three times of x minus twelve

Now take 2y to RHS side

3x-2y-12=0

3x-2y=12

Hence 3x-2y=12 is the standard Form of equation y=3/2x - 6.

The sum of the interior angle measures of the polygon is 540°

Step-by-step explanation:

The formula of the sum of the measures of the interior angles of a polygon is

∑m = (n - 2) × 180°, where n is the number of the sides of the polygon

In the given figure

∵ The polygon has 5 sides

n = 5

→ Use the formula above to find the sum of the interior angle measures of it

∵ ∑m = (5 - 2) × 180°

∴ ∑m = 3 × 180°

∑m = 540°

The sum of the interior angle measures of the polygon is 540°

An engineer designed a new bridge and drew the scale drawing shown below. 6 Inches If the engineer used the scale 3 inch = 40 feet, how long is the actual bridge the engineer designed?​

Answers

Answer:

The bridge is 80 feet long

Step-by-step explanation:

We will use the ratio method to solve the question

∵ The engineer used the scale 3 inch = 40 feet

∴ The scale drawing is ⇒ 3 inche :  40 feet

∵ The drawing length of the bridge is 6 inches

→ By using the ratio method

→  inch :  feet

→  3      :  40

→  6      :  x

→ By using cross multiplication

3 × x = 6 × 40

∴ 3x = 240

→ Divide both sides by 3

x = 80

∵ x represents the actual length of the bridge

The bridge is 80 feet long
