Answer:
y = 4x + 13
Step-by-step explanation:
m = 4 at point (-3,1)
y = 4x + b
1 = 4(-3) + b
1 = - 12 + b
b= 13
y = 4x + 13

Answer:
h = 12 m
Step-by-step explanation:
Sides of the triangle are proportional.
(3.6 m)/(1.2 m) = h/(1.2 m + 2.8 m)
(4 m)(3.6/1.2) = h . . . . . multiply by 4 m
h = 12 m
hello, could someone help me with this question, thank you.
It's C.
Basically, when youre dividing something, the bases would stay the same but the exponents would change. For division, you'd have to substract the exponent of the denominator from the denominator (of like bases, of course)
In this case, it's 10^8-(-3).
The only reason it's not 10⁵ is because of the negative 3. If it were a positive 3, it would become 10⁵.

What steps must you take to divide fractions?
Answer:
Find a reciprocal.
Step-by-step explanation:
ex: If you have 5/6 divided by 3/7 you would flip the 3/7 so it's 7/3 so then you can simply multiply them. REMEMBER YOU CANNOT DIVIDE FRACTIONS. YOU MUST CHANGE THE PROBLEM INTO MULTIPLICATION FIRST!!!

finished
Answer:
Step-by-step explanation:
(8b+12)+(3n+6)+(9b-4)
Remove the parentheses:
8b+12+3n+6+9b-4
Group like terms:
8b+9b+3n+12+6-4
Add the similar element:8b+9b=17b
=17b+3n+12+6-4
add/subtract the numbers:12+6-4=14
=17b+3n+14

Which pair of functions are inverses of eachother?
Answer:
D
Step-by-step explanation:
A.
y= 6x³
to find the inverse substitute x for y and y for x and solve for y
x= 6y³ ; divide both sides by 6
x/6 =y³ ; cube root both sides
(∛x)/ ∛6 = y
so (∛x)/6 and 6x³ are NOT inverse of each other
B
y= (x+2)/5
x= (y+2)/5; multiply by 5
5x = y+2; subtract 2
y= 5x-2 NOT corect
C
y = 5x-6
x= 5y-6; add 6 to both sides
x+6 = 5y ; divided by 5 both sides
y = (x+6)/5 is NOT correct
D
y=7x -2
x= 7y-2
x+2 = 7y , (x+2) /7 = y so IS correct
