f(x)=-4x-6 and g(x)=3x+5. Find (f o g)(-3) plzzzzzzzzzzz helpppppppp
Answer:
(f o g)(-3) = 10Step-by-step explanation:
f(x) = - 4x - 6
g(x)=3x+5
To find (f o g)(-3) we must first find
(f o g)(x)
To find (f o g)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)
That's
(f o g)(x) = - 4( 3x + 5) - 6
= - 12x - 20 - 6
(f o g)(x)= - 12x - 26
Now to find (f o g)(-3) substitute the value of x that's - 3 into (f o g)(x) and solve
We have
(f o g)(-3) = - 12(-3) - 26
= 36 - 26
We have the final answer as
(f o g)(-3) = 10
Hope this helps you
Which expression gives the distance between the points (3, -8) and (3, -19)? *
1 point
Captionless Image
|3 - 3|
|-19 - (-8)|
|3 + (-19)|
|3 - (-8)|
| 3 + (-19) |
Answer:
| - 19 - (- 8) |
Step-by-step explanation:
Given that the 2 points have the same x- coordinate, then the distance between the 2 points is the difference in the y- coordinates, that is
distance = | - 19 - (- 8) | = | - 19 + 8 | = | - 11 | = 11
Or
distance = | - 8 - (- 19) | = | - 8 + 19 | = | 11 | = 11

A 50 litre solution of acid and water contains 10 litres of acid. How much water must be added to make the solution 8 % acidic. Will mark brainest to whoever answers.
Answer:
Your welcome!Step-by-step explanation:
Acid present in the solution = 10 L
Required volume concentration of acid = 8/100
Let x amount of water be added to achieve the required %.
In the new solution, proportion of acid= 10/(50+x)
Therefore,
10/(50+x) = 8/100
x=75
Ans: 75 L of water must be added to the solution

What is the range of the function graphed below?
Answer: C -3< y ≤ 3
Step-by-step explanation:
Starting from the lowest point of the y coordinate to the highest point of the y coordinate. The lowest point is -3 and highest point is 3.At the y coordinate -3 there is an open circle which means we are excluding it and at the highest point 3 there is a closed circle so we will have to include that.

Suppose a social networking site has roughly 1,000,000 users, and as each
member signs up for an account, he or she is assigned a number. Which of these would result in the largest sample size using systematic sampling?
A. Surveying every 25,000th number
B. Surveying every 25th number
C. Surveying every 250th number
D. Surveying every 2,500th number.
The option that results in the largest sample size using systematic sampling is; Surveying every 25,000th number
How to find the Sample Size?
If the numbers of people are assigned in order of 1 to 1,000,000 then the smallest sample would be obtained by conducting surveys every 25 000th numbers.
The calculation of the sample size would be made by dividing 1, 000,000 by 25000.
1,000,000/25000 = 40
Therefore, the smallest sample selected would be 40 people.
If the surveys were made every 25th numbers, then the sample size would be:

Answer:
The lengths of the sides are 30 ft, 60 ft, 15 ft, 45 ft
Step-by-step explanation:
The perimeter is 150 ft, the length of the fence.
We add the lengths of the sides and set equal to the perimeter. Then we solve for x. Once we know x, we find the length of each side.
x + 2x + 0.5x + 45 = 150
3.5x = 105
x = 105/3.5
x = 30
Lengths of sides:
x = 30
2x = 2(30) = 60
0.5x = 0.5(30) = 15
45
Answer: The lengths of the sides are 30 ft, 60 ft, 15 ft, 45 ft

– 5 | 3 z + 8| –5 = -20
I'm assuming you want to solve for z :)
By simplifying both sides of the equation, then isolating the variable.
Exact form:
z= -5/3 , - 11/3
Mixed number form:
z= −1 2/3 , −3 2/3
Answer:
There are two solutions, -5/3 and -11/3
Step-by-step explanation:
Move -5 to the right side and add:
-5 | 3x + 8 | = -15
Get rid of the absolute-value bars by splitting them into negative and positive cases.
Solve negative case
-5 ( 3z + 8 ) = -15
Distribute or Multiply:
-15z - 40 = -15
Rearrange and Add:
-15z = 55
Divide both sides by 15:
-z= 11/3
Multiply both sides by -1:
z= -11/3
Solve negative case
5 ( 3z + 8 ) = -15
Distribute or Multiply:
15z + 40 = 15
Rearrange and Add:
15z = -25
Divide both sides by 15:
z = -(5/3)
Answer
z=-11/3
z=-5/3
