Mathematics
1 answer:
olga_2 [115]3 years ago
8 0

Answer:

x=5

Step-by-step explanation:

4x^2-11=89

add 11 to both sides

4x^2=100

Divide 4 on both sides

x^2=25

Take the square root of both sides to eliminate the power of two from x

\sqrt{x^2} =\sqrt{25}

Simplify

x=5

What is the value of x?
dusya [7]
X = 8. You can find this by adding 90 (from the shown 90 angle to 18 and then subtracting 180-102 = 9x to since angle LJW is known to be 180 degrees (since its a straight line). Solving we get 72 = 9x.
Divide both sides by 9
X = 8

I hope this helps!

Which equation represents the line shown?
aleksandrvk [35]

Answer:

the first option

Step-by-step explanation:

okay so the line passes through the 2 on the y-axis making it the y-intercept

that means you can eliminate the second and third options

now to find the slope, you can use rise over run (y2-y1/x2-x1)

3-2/3-0 = 1/3

so the slope is 1/3

all together, the equation would be:

f(x) = 1/3x + 2

so the answer is the first option
