Answer:

y=2x+6

Step-by-step explanation:

to find the slop you divide the difference in y over difference in x, therefore its (14-10)/(4-2) which is 4/2 aka 2

then to find the y intercept, you can plug in a point, it doesn't matter which one.

so 10 = 2(2) + b --> 10 = 4+b, b is 6

so y = 2x+6

2(3+9x) answer this for me plz lol
Gre4nikov [31]

Answer:

6+18x

Step-by-step explanation:

You typically would use PEMDAS in this situation but in the parenthesis, you can't add the 3 and the 9x together, so you just skip to 2*3 and 2*9x

I cant figure this one out at all
eduard

Answer:

a. 2^(x-2) = g^(-1)(x)

b. A, B, D

Step-by-step explanation:

the phrasing attached in the image is flagged as inappropriate, so i will be replacing it with g(x) and its inverse with g^(-1)(x)

1. replace g(x) with y and solve for x

y = log₂(x) + 2

subtract 2 from both sides to isolate the x and its log

y - 2 = log₂(x)

this text is replaced by the second image -- it was marked as inappropriate

thus, 2^(y-2) = x

replace x with g^(-1)(x) and y with x

2^(x-2) = g^(-1)(x)

2. plug this in to points A, B, C, D, E, and F

A: (2,1)

plug 2 in for x

2^(2-2) = 2⁰ = 1 so this works

B: (4, 4)

2^(4-2) = 2²= 4 so this works

C: (9, 3)

2^(9-2) = 2⁷ = 128 ≠ 3 so this doesn't work

(5, 8)

2^(5-2) = 2³ = 8 so this works

E: (3, 5)

2^(3-2) = 2¹ = 2 ≠ 5 so this doesn't work

F: (8, 5)

2^(8-2) = 2⁶ = 64 ≠ 5 so this doesn't work

Solve for x.<br><br> 3/5x + 1/4x=51<br> x=?
Tanzania [10]

Answer:

x=60

Step-by-step explanation:

3/5x + 1/4x=51

12/20x+5/20x=51

17/20x=51

17x=1020

x=60

Double-Check:

3/5(60)+1/4(60)=51

180/5+60/4=51

36+15=51

51=51

Hope it helped!
