Answer:

x=20

Step-by-step explanation:

log3(4x+1) = 4

Raise each side to the base of 3

3^log3(4x+1) = 3^4

4x+1 = 3^4

4x+1 = 81

Subtract 1 from each side

4x+1-1 = 81-1

4x= 80

Divide by 4

4x/4 = 80/4

x = 20

Answer:

Step-by-step explanation:

The formula of an area of a trapezoid:

$A=\dfrac{b_1+b_2}{2}\cdot h$

b₁, b₂ - bases

h - height

We have b₁ = 10in, b₂ = 5in and h = 11in. Substitute:

$A=\dfrac{10+5}{2}\cdot11=\dfrac{15}{2}\cdot11=7.5\cdot11=82.5\ in^2$

Find the y-intercept and the slope of the line<br><br> y=-x+7<br><br> y-intercept:<br> slope:

Ipatiy [6.2K]

Answer:

The y-intercept would be 7

The slope would be -1 or -1/1. They are both the same thing.

The slope is the number which is located directly to the left of the variable (the variable in this case is x, but in other situations it could be a totally different letter).
