Answer:
A.
Step-by-step explanation:
In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D
It isn't a gradual line, as 6x is, so that is eliminated.
When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times. If you then connect the dots, it will be a line probably very close to your estimate.

HELP ME PLEASE
A certain drug is made from only two ingredients: compound A and compound B. There are 4 milliliters of compound A used for every 7 milliliters of compound B. If a chemist wants to make 1012 milliliters of the drug, how many milliliters of compound A are needed?
These are proportions.
Answers
Answer:
368 milliliters.
Step-by-step explanation:
Compound A + Compound B = 1 drug
4 + 7 = 1 drug
11 milliliters = 1 drug, so 1012 milliliters = 92 drugs
Multiply the compounds by the amount of drugs, e.g.
4 x 92 = 368 ( Compound A )
7 x 92 = 644 ( Compound B )
368 + 644 = 1012
368 milliliters of Compound A are needed to make 1012 milliliters of the drug.
Hope this helps :)

What is the value of x? Pls help
Answers
Answer:
x=20
Step-by-step explanation:
ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540
so we setup an equation which would be
7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x
step 1 combine like terms
7x+4x=11x
11x+4x=15x
15x+5x=20x
20x+6x=26x
5+10=15
15-5=10
10+10=20
now we have
20+26x=540
step 2 subtract each side by 20
20-20 cancels out
540-20=520
now we have 26x=540
the final step is to divide each side by 26
26/26 cancels out
540/26=20
x=20

-5?
y= 3x +1
Answers
Answer:
Step-by-step explanation: both graphed is D
The graph D represents the solution of the system of the equation.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given, the system of equation;
y = -3x - 5 {equation 1}
y = 3x + 1 {equation 2}
Add both of the equation:
2y = -4
y = -2
And x = 1
And the solution set is (1 , -2).
And only D have the solution set (1 , -2)
Therefore, the graph D represents the solution of the system of the equation.

Answers
Step-by-step explanation:
The formula for exponetial equation decay is
[tex]y = a(b) {}^{x} [/tex]
where a is the initial value and b is the decay factor.
A will be 56 since that our initial value.
b will be 0.9 since we are constantly decaying by 0.9.
so our equation is

Sarah is having people over for her birthday party. If she orders 4 pizzas for 15 people, how many should she order for 30 people?
Answers
Answer: 8
Step-by-step explanation:
Answer: 8 pizzas.
Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.

an answer is precise when it is an exact number like 10, 2, or 123.
An answer is approximate when the decimal numbers are so close that could round it, and the rounded number would be equivalent to the original number. ex: 10.98 = 11

Plot the zeros of this function:
f(x) = (x – 1)(x – 7).
Answers
Answer:
Zeros of the given function are x = 1, 7
Step-by-step explanation:
Given function is,
f(x) = (x - 1)(x - 7)
For zeros of the function,
f(x) = 0
(x - 1)(x - 7) = 0
(x - 1) = 0
x = 1
(x - 7) = 0
x = 7
Therefore, zeros of the given function are x = 1, 7
We can find the zeros by suing a graphing tool.
Determine all the transformations that have happened to f(x) = (x + 4)2 + 2 compared to
f(x) = x2
Answers
Answer:
Folow the steps to learn what transformations were determined.
Step-by-step explanation:
First we would have to graph the parent function which is f(x) = x^2. Start by finding your x and y values. Find the y values by plugging in the x values into the parent function.
X Y
2 4
1 1
0 0
-1 1
-2 4
Once these points are plotted you can start determining what are the transformations. Find the difference between the parent function and f(x) = (x + 4)^2 + 2 by looking below.
Vertical Shifts:
f(x) + c moves up,
f(x) - c moves down.
Horizontal Shifts:
f(x + c) moves left,
f(x - c) moves right.
The parent function has to be transformed left 4 and up 2. In order to do this shift each point from earlier left 4 and then up 2. In conclusion you will have two functions graphed (parent function and the transformed function).

Answers
Answer:
x=15 degrees
Step-by-step explanation:
You know that the right angle is split in half to 45 degrees and 3x degrees. Because a right angle is equal to 90 degrees, 3x has to be equal to 45. Therefore, the equation will be 3x=45. You want to make x equal one so you have to divide 3 by each side. The equation will be x=45/3. Simplify that to get x=15. Therefore, x=15 degrees.

Step-by-step explanation:
It can-t be A, because that would mean 20², which equals 400, would equal 20.
B is correct because even though it's negative, negative times negative = positive, which would mean that (-sqrt of 20)(-sqrt of 20)=20.
C is wrong because sqrt -20 is an imaginary number,which is a completely different topic.
D is correct because it's the same thing as B, but without the 2 negaties cancelling each other out.
E is the same as A, except it's '-20' x '-20', whcih is still 400, which is still wrong
