Answer:

$\text{The product is -45+18x}$

Step-by-step explanation:

Given the expression

$-9(5-2x)$

we have to find the product.

$-9(5-2x)$

By distributive property,

$a(b+c)=ab+ac$

$\text{Put a=-9, b=5 and c=-2x}$

$-9(5+(-2x))=-9(5)+(-9)(-2x)=-45+18x$

which is the required product.

Solve the equation for y.<br><br> 6y+x=8

iVinArrow [24]

Answer:

The correct answer is $\bold{y = -\frac{1}{6}x+\frac{4}{3}}$ .

Step-by-step explanation:

We want to solve for y in the given equation. We can do this by rearranging the equation and using operational techniques to simplify.

$6y + x = 8 \ $\tex Subtract x from both sides of the equation.$

$6y + x - x = 8 - x \ $\tex Carry out the operation.$

$6y = 8 - x \ $\tex Rearrange so the equation lists the variables first and the constants second.$

$6y = -x + 8 \ $\tex Create a coefficient for the x-variable (this is -1).$

$6y = -1x + 8 \ $\tex Divide by 6 on both sides of the equation in order to isolate the y-variable.$

$\frac{6y}{6}=\frac{-1x}{6} + \frac{8}{6} \ $\tex Carry out this operation by simplifying the fractions and dividing out the operations accordingly.$

$y = -\frac{1}{6}x+\frac{4}{3} \ $\tex Be sure to verify that all fractions and terms are simplified as far as they can be and that the equation is written in proper syntax.$

Because we have the <em>y</em>-variable isolated from the rest of the equation, we are done!

Can someone please help me please I really need help please help

mr Goodwill [35]

Answer:

K'(4, -4)
L'(8, -4)
M'(8, 8)
N'(4, 8)

Step-by-step explanation:

Dilation centered at the origin multiplies every coordinate value by the scale factor.

K(1, -1) ⇒ K' = 4(1, -1) = (4, -4)

L(2, -1) ⇒ L' = 4(2, -1) = (8, -4)

M(2, 2) ⇒ M' = 4(2, 2) = (8, 8)

N(1, 2) ⇒ N' = 4(1, 2) = (4, 8)

Answer:

Step-by-step explanation:

$\sqrt[4]{144a^{12}b^{3}} = \sqrt[4]{4^{2}*3^{2}a^{12}b^{3}}=\\= \sqrt[4]{2^{4}*3^{2}a^{12}b^{3}}=2a^{3}\sqrt[4]{3^{2}b^{3}} =\\}=2a^{3}\sqrt[4]{9b^{3}}$
