-3a-4(a-6)=24-7a
-3a-4a+24=24-7a
-7a+24=24-7a
-7a+24=-7a+24
-7a+24-24=-7a+24-24

Answer:
x = -5
Step-by-step explanation:
move the variable tothe left hand side change the sign
-x-7= -2
Calculate the sum
-x =5
change the sign on both of the equations
x =
The equation which represents the given graph g(x) is 2ˣ-1.
<h3>
What is Equation?</h3>
Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.
Here, given graph passes through origin.
Put x = 0 in all the given equation and verify which equations gives result as zero.
Put x = 0 in option A
g(0) = 2⁰⁺¹ = 2 ≠ 0
in option B
g(0) = 2⁰-1 = 1 - 1 = 0
Thus, option B g(x) = 2ˣ-1 is the correct expression for the given graph.

Answer:
48+14i
Step-by-step explanation:
So squaring (i+7) looks like this
(i+7)^2
(i+7)(i+7)
Use foil.
First: i(i)=i^2=-1
Outer: i(7)=7i
Inner: 7(i)=7i
Last: 7(7)=49
____________Add the terms.
48+14i
Answer:
1⅙ gal
Step-by-step explanation:
⅔ × ⁷/₄ Cancel 2s
= ⅓ × ⁷/₂ Multiply numerators and denominators
= ⁷/₆ Convert to a mixed number
= 1⅙
The container holds 1⅙ gal when it is ⅔ full.
