Answer:

  1. \huge{x =  -  \frac{5}{4}  +  \frac{7}{4} y}
  2. \huge{x =  -  \frac{7}{3}  +  \frac{2}{3} y}

Step-by-step explanation:

1. 4x - 7y =  - 5

4x =  - 5 + 7y

\boxed{\green{x =  -  \frac{5}{4}  +  \frac{7}{4} y}}

y E R

○○•○○

2. 3x - 2y =  - 7

3x =  - 7 + 2y

\boxed{\green{x =  -  \frac{7}{3}  +  \frac{2}{3} y}}

y E R

For what value is a is (a,9) a solution of the equation y=2x+1
yanalaym [24]

Answer:

a = 4

Step-by-step explanation:

y = 2x + 1 ......(1)

Going through y - y1 = m(x - x1)

m is slope and it is 2

y1 = 9 and x1 = a

y - 9 = 2(x - a)

y - 9 = 2x - 2a

y = 2x - 2a + 9 ........(2)

Equating (1) and (2)

2x + 1 = 2x - 2a + 9

Collecting like terms

2x - 2x + 2a = 9 - 1

2a = 8

a = 8/2

a = 4

B
bearhunter [10]

Claim: The measures of \angle B and \angle B' are equal

Answer: True

Explanation: Dilations preserve the shape of an image, so this means the angles are kept the same whether you shrink or enlarge the preimage.

====================================================

Claim: The coordinates of A and A' are the same

Answer: True

Explanation: The phrasing "dilating about point A" means that point A is the center of the universe, so to speak, in terms of this dilation operation. Point A is the fixed point that does not move while every other point does move. Because the scale factor is 2/3, which is less than 1, this means every other point comes closer to point A. So something like segment AB will get shorter.
