Answer:

Step-by-step explanation:

Given points ( 7 , 20) and ( -2 ,11)

First calculating slope

Slope (m)

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

= ( 20 - 11) / ( 7 + 2)

= 9/9

= 1

Now the equation of line is given by

y - y1 = m( x - x1)

y - 11 = 1( x + 2)

y - 11 = x + 2

x - y = - 11 - 2

x - y = - 13

x - y + 13 = 0

Hope it will help :)

Answer:

Step-by-step explanation:

y-20=(11-20)/(-2-7)(x-7)

y-20=-9/-9 (x-7)

y-20=x-7

y=x-7+20

or y=x+13

Geri believed the answer to one of her homework problems was 2 cubed. After checking her work, she realized the correct answer w

TiliK225 [7]

Answer:

The correct answer is 64 times Geri’s original answer

Step-by-step explanation:

Given

Gari's Answer: 2³

Correct Answer: 2⁹

Required:

Relationship between both answers

Let Gari's answer be represented by G and the Correct answer be represented by C; Such that

G = 2³

C = 2⁹

Divide C by G

$\frac{C}{G} = \frac{2^9}{2^3}$

From law of indices, $\frac{a^m}{a^n} = a^{m-n}$

Applying this law, we have

$\frac{C}{G} = 2^{9-3}$

$\frac{C}{G} = 2^{6}$

$\frac{C}{G} = 2*2*2*2*2*2$

$\frac{C}{G} = 64$

Multiply both sides by G

$G * \frac{C}{G} = 64 * G$

$C = 64G$

Hence, we can conclude that the correct answer is 64 times Geri’s original answer
