Answer:

c, b, d

Step-by-step explanation:

4. 9^6 is the same thing as multiplying 6 9's, which is option C.

5. Since they have the same base, we can subtract the exponents to get 4^6, or option B.

6. When you have a^(-m), you write it as 1/a^m. In this case, we have 1/(2/3)^3 = 1/(8/27) = 27/8, which is option D. Hope this helps!

Help!Write the equation in slope- intercept form of the line that passes through (−1, 11) and is parallel to the graph of y = −8

love history [14]

Answer:

y = -8x + 3

Step-by-step explanation:

plug in the point and the slope into the slope intercept formula (y=mx+b)

the slope will be the same since you want the line to be parallel

11 = -8(-1) +b now solve for b

11 = 8 + b

-8 -8

3 = b

now write the equation with only the slope and the y intercept

y = -8x + 3

True or false? A correct answer is worth (2 pts). Explain how you know for the additional (2 pts). Using complete sentence for (

PtichkaEL [24]

answer (in words)

FALSE. the coordinate pair (5, 2) is not a solution to the equation $2x+3y=10$ . in order to figure out whether or not the statement is true or false, plug the $x$ and $y$ values from the coordinate pair (5, 2) into the given equation, $2x+3y=10$ . if both sides of the equation end up equal, the coordinate pair is a solution to the equation. if not, the coordinate pair is not a solution to that equation.

(i hope i explained that well enough, i'm better at explaining it algebraically as opposed to putting it into words lol)

answer (algebraic/steps for solving)

first, plug in 5 for $x$ in the equation $2x+3y=10$ .

$2x+3y=10$ ⇒ $2(5)+3y=10$

then plug in 2 for $y$ .

$2(5)+3y=10$ ⇒ $2(5)+3(2)=10$

now your equation is $2(5)+3(2)=10$ . all that's left to do is to simplify. you can do this in whatever order you'd like, but i'll start with multiplying 2 · 5.

$2(5)+3(2)=10$ ⇒ $10 + 3(2) = 10$

multiply 3 · 2.

$10 + 3(2) = 10$ ⇒ $10 + 6 = 10$

add 10 + 6.

$10 + 6 = 10$ ⇒ $16=10$

16 and 10 are not equal, therefore (5, 2) is not a solution to the equation $2x+3y=10$ . in order for a coordinate pair to be the solution to an equation, both sides of the equation need to end up equal after solving and simplifying.

i hope this helps! have a great rest of your day <3
