Hello from MrBillDoesMath!

Answer: B

Remark: It is customary to use x^2, not x2, to indicate the square of x.

Discussion:

(4x + 3) ^ 2= ( 4x)^2 + 2 * (4x)(3) + 3^2 =

16 x^2 + 24x + 9

Thank you,

MrB

Please help! Find the slope -2x + 4y = 36 Thank you!

kogti [31]

-2x+4y=36
Add +2x to both sides
4y=2x+36
Decide every term by 4
y= 2/4x + 9

The slope is 2/4

Write down down an equation of a line that is parallel to the line with the equation y=7-x

Bingel [31]

Answer:

y=8-x or y=9-x or y=243-x (The spot where the 8 is can be any number as long as the number infront of the 0 is still -1)

ASAP someone please simply two exponents

zhannawk [14.2K]

Answer:

1.) $m^{15}$

2.) $=\frac{1}{y^{15}}$

Give me a comment if you want the explanation.

1.) $\mathrm{Apply\:exponent\:rule:\:}\left(a^b\right)^c=a^{bc},\:\quad \mathrm{\:assuming\:}a\ge 0$

$\left(m^3\right)^5=m^{3\cdot \:5}$

$\mathrm{Multiply\:the\:numbers:}\:3\cdot \:5=15$

$=m^{15}$

2.) $\mathrm{Apply\:exponent\:rule:\:}\left(a^b\right)^c=a^{bc},\:\quad \mathrm{\:assuming\:}a\ge 0$

$\left(y^{-3}\right)^5=y^{-3\cdot \:5}$

$=y^{-3\cdot \:5}$

$=y^{-15}$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}$

$=\frac{1}{y^{15}}$

Find the equation of the line using exact numbers

Katen [24]

Answer:

y = - $\frac{1}{3}$ x + 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

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

with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (3, 4) ← 2 points on the line

m = $\frac{4-5}{3-0}$ = $\frac{-1}{3}$ = - $\frac{1}{3}$

the line crosses the y- axis at (0, 5 ) ⇒ c = 5

y = - $\frac{1}{3}$ x + 5 ← equation of line
