Answer:

A

Step-by-step explanation:

The difference between the values of y are constant, that is

17 - 13 = 13 - 9 = 9 - 5 = 4

This indicates the relationship is linear.

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 7, 5) and (x₂, y₂ ) = (- 5, 9) ← 2 ordered pairs from the table

m = \frac{9-5}{-5+7} = \frac{4}{2} = 2

Use any ordered pair from the table for (a, b)

Using (a, b) = (- 7, 5), then

y - 5 = 2(x - (- (- 7)) , that is

y - 5 = 2(x + 7) → A

Answer:

Let's see the first two points: (-7, 5) and (-5, 9)

The line passes these points has a form of: y = Mx + b

=> 5 = (-7)M + b

   9 = (-5)M + b

Subtract the 1st equation from 2nd equation, we have:

4 = 2M

=> M = 2

Substitute M back into 1st equation:

=> 5 = (-7)*2 + b

=> b = 19

=> y = 2x + 19

or y - 5 = 2x + 14

or y - 5 = 2(x + 7)

=> Option A is correct

Hope this helps!

Can someone help me? Please and thank you! <3

Answer:

I think it would be 40?

Step-by-step explanation:

I think 40 because if I recall correctly, to find the range you must subtract the max from the min, the max being 100 and the min being 60 in this case.

Find the equation of the line passing through the point (6,3) that is perpendicular to the line 4x−5y=−10.
Paul [167]

Step-by-step explanation:

( y = 4x/5 + 2)

m1.m2 = -1

4/5.m2 = -1

m2 = -5/4

formula = y - y1 = m2 ( x - x1)

y - 3 = -5/4 ( x - 6)

y -3 = -5x /4 + 30/4

y = -5x /4 + 21/2

-4x + 11y = 15<br><br> x=2y<br><br><br> Solve for y and x
Stolb23 [73]

Answer:

to find Y

-4x + 11y = 15

x - 2y = 0

.

equal= -3x + 9y= 15

since x=2y

-3(2y) + 9y = 15

-6y + 9y =15

3y = 15

y = 15/ 3

y = 5

.

to find x

using x=2y

since

y=5

,therefore

x= 2(5)

x= 10

Sliva [168]

Answer:

223 (rounded to closest one) actual answer would be 222.91479275

Step-by-step explanation:

use formula A=Pe^nt

$280 = Pe^0.019(12)

$280 = Pe^0.228, then evaluate the solution by isolating the variable and dividing each side by the factors which don't contain the variable.

P = 222.91479275
