The answer would be A!

Whenever there is a fraction in the exponent, the numerator is under the square root, and the denominator is on the outside of the square root!

Additionally, since the negative is outside of the square toot, then it also outside of the parenthesis.

URGENT 30 points I need help

Ostrovityanka [42]

Answer:

- 112 + 100 n

Step-by-step explanation:

$a_{n}$ = $a_{1}$ + (n - 1 )d

~~~~~~~

$a_{1}$ = - 12

d = 100

$a_{n}$ = - 12 + 100( n - 1 )

$a_{n}$ = - 12 + 100n - 100

$a_{n}$ = - 112 + 100 n

Write the equation of a line that is parallel to y = 7x +13 that passes through the point (28, 8).

navik [9.2K]

Answer:

y=7x-188

Step-by-step explanation:

We know that this line must have a slope of 7, because this line is parallel to y=7x+13

We must use the point slope formula: y- $y_{1}$ = m(x- $x_{1}$ )

Next, we will plug in the point (28,8) for $y_{1}$ and $x_{1}$ , and 7 in for m

y-8=7(x-28)

Solve the equation, first by distributing the 7

y-8=7x-196

Add the 8 over

y=7x-188
