What is the answer QUICKLY PLZ −6+|2x+7|=−10
Step-by-step explanation:
x=3/2 it's the final result
Answer:
-5.5
Step-by-step explanation:
-10 - -6 = -4
2x+7 = -4
-4 - 7 = -11
2x = -11
x = -5.5
The function y = 2x + 8 represents the cost y (in dollars) of a large pizza with x toppings, where x
is equal to 0, 1, 2, or 3.
Identify the independent and dependent variables, the domain, and the range.
Answer:
0 ,1,2,3,/ is range/ y is the independent varibal/ x is the dependent varible/ /the equation is the domain
Step-by-step explanation:
The domain and independent variables are 0, 1, 2, and 3.
The range and dependent variables are 8, 10, 12, and 14.
What is a function?A function is defined as a relation between a set of inputs having one output each.
Inputs are called the domain and independent variables.
Outputs are called the range and dependent variables.
We have,
y = 2x + 8
y = cost of pizza in dollar
x = toppings on pizza
x = 0, 1, 2, or 3
y = 2 x 0 + 8 = 8
y = 2 x 1 + 8 = 2 + 8 = 10
y = 2 x 2 + 8 = 4 + 8 = 12
y = 2 x 3 + 8 = 6 + 8 = 14
Thus,
The domain and independent variables are 0, 1, 2, and 3.
The range and dependent variables are 8, 10, 12, and 14.

On a scaled map, 1.25 inches = 10 miles. The

A. 26 miles

Answer:

Step-by-step explanation:
Given that the equation y=mx + b where m is 12 and the line passes through the point (-2,8), what would be the value of b?
a. b = -16
b. b = -8
c. b = 16
d. b = 32
Answer:
d
Step-by-step explanation:
The answer would be D. We can continue the line from the point (-2,8) because we know the slope so we will continue it forward by two on the x axis. Since we go forward by two we are going up by 24 (12*2) on the y axis so the y intercept (b) would be 8 + 24 which is 32. Sorry if it is hard to understand.

Can someone help my sis on these questions? I dont remember how to do these things (part 1)
Answer:
Read below for each answer! (^-^)
Step-by-step explanation:
1: You got the first one right. The explanation does explain why but think about 0 as the surface of the water to better understand.
2: -3; it is between 2 and 4 with only one line through it meaning that it is -3.
3: 7. That's the greatest number both can divide into it.
4: The last one. Any positive number is greater than a negative one and peanut butter's freezing point is positive while the other one's is not.
5: You got it right again! -(-1) has two negatives. Two negatives (mostly) make a positive. So positive 1! Now describe that on a number line.

A copy machine is set to enlarge an image 160%. If the original image is 3 inches tall, how
tall will the enlarged image be?
O about 480 in.
about 163 in
O about 4.8 in.
O about 4.6 in.
Answer:
The enlarged image will be about 4.8 inches
Step-by-step explanation:
Here, we want to know how tall the image will be
Mathematically;
That will simply be 160% of 3 inches
We have;
160/100 * 3 = 480/100 = 4.8 inches

The first number is 7 greater than a second number. Twice the first number is 4 more than three times the second. Find the two numbers.
Step-by-step explanation and answer:
Setting up a system of equations would be the easiest method for this question. The first number will be x. The second number will be y. According to the question:
x+1=y
2x-4=5y
Since the first equation is already solved for y, you can plug the whole first equation in for y in the second equation, then solve for x.
2x-4=5(x+1) Distribute the 5
2x-4=5x+5 Subtract 5x from 2x
-3x-4=5 Subtract -4 from 5 (add 4 to 5)
-3x=9 Divide to get the x by itself
-3=x
Now that you have x solved for, you can plug it into the first equation (or second, if you prefer) to solve for y.
x+1=y
-3+1=y
-2=y

Solve for z:

Answer:
z=2
Step-by-step explanation:
14=z+12
2=z
Answer: The answer is z=2.
Step-by-step explanation: Step 1. Simplify the both sides of the equation: [tex]14=z+12[/tex].
Step 2. I flipped the equation that looks like this: [tex]z+12=14[/tex].
Last but not least is step 3. Subtract 12 from the both sides: [tex]z+12-12=14-12[/tex]; ∴, your answer should be z=2, I hoped this helps, Happy New Year, and mark me as brainliest. :D

The system of equations below has exactly one (x, y) pair for its solution.
4x+6y=244x+6y=24
2x+y=82x+y=8
If we double each side of the second equation, 2x+y=82x+y=8, we have 4x+2y=164x+2y=16. Explain why the same pair that is the solution to the system is also a solution to this new equation.
If needed, you can support your explanation with hanger diagrams (upload a picture), or by inventing a situation that the equations represent.
If we add the two equations in the original system, we have 6x+7y=326x+7y=32. Explain why the same (x, y) pair is also a solution to this equation.
Again, you can support your explanation with diagrams or a situation, if needed.
