Mathematics
1 answer:
olga nikolaevna [1]3 years ago
8 0

Given:

The function is

f(x)=4x-8

To find:

The input of the function when the output is 20.

Solution:

We have,

f(x)=4x-8

Here, x is input and f(x) is output.

Put f(x)=20 in the given function to find the input of the function when the output is 20.

20=4x-8

20+8=4x

28=4x

Divide both sides by 4.

\dfrac{28}{4}=x

7=x

Therefore, the required input value is 7.

The following triangle is equilaterial triangle. Solve for the unknown variable.
Iteru [2.4K]

Answer:

d

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent, then

2x = 6 ( divide both sides by 2 )

x = 3

and

3y = 6 ( divide both sides by 3 )

y = 2

Thus x = 3 and y = 2 → d

Write an equation in slope intercept form of the line containing the points (-2,5) and (9,-6)
otez555 [7]
(-2,5)(9,-6)
slope(m) = (-6-5) / (9 - (-2) = -11/11 = -1

y = mx + b
slope(m) = -1
(-2,5)...x = -2 and y = 5
now we sub and solve for b, the y int
5 = -1(-2) + b
5 = 2 + b
5 - 2 = b
3 = b

so ur equation in slope intercept form is : y = -x + 3
