Given the function y= 2x if x>0 x−3 if x≤0 . Find its values for x=1; 3; 0; −2. Answer: If x = 1, then y = . If x = 3, then y = . If x = 0, then y = . If x = −2, then y = .
Answers
Answer:
Step-by-step explanation:
Given the function y= 2x if x>0 and x−3 if x≤0, to find the value of the function for x = 1, we will substitute x = 1 into the function y = 2x since x>0 at that point.
If x = 1;
y = 2(1)
y = 2
Hence when x = 1, y = 2
If x = 3, we will still use the function y = 2x since 3 is still grater than 0 satisfying the condition x>0.
y = 2(3)
y = 6
Hence when x = 3, y = 6
when x = 0, since x is zero, we will substitute x = 0 into the function x-3 because x≤0 at this point.
If y = x-3
y = 0-3
y = -3
Hence when x = 0, y = -3
when x = -2, we will substitute x = 0 into the function x-3 because -2 is also less than zero
If y = x-3 for x≤0
y = -2-3
y = -5
Hence when x = -2, y = -5

A craft store sells boxes of two different varieties of colored pencils. The table shows the number of boxes sold last month. What is the total dollar amount of colored pencils sold?
Answers
Answer:
So the answer is 108.75
Step-by-step explanation:
15 * $4.25 = 63.75
12* $3.75 = 45
63.75 + 45 = 108.75.
Answer:108.75
The total dollar amount of coloured pencils sold is $108.75.
Given that, a craft store sells boxes of two different varieties of coloured pencils. The table shows the number of boxes sold last month.
We need to find what is the total dollar amount of coloured pencils sold.
What is the tally table?A tally table is a table that represents the occurrence of an event in a way that calculates it becomes easy.
Now, the cost of each pencil is $4.25.
Then the cost of 15 pencils=15×4.25=$63.75
The cost of each pencil is $3.75.
Then the cost of 12 pencils=12×3.75=$45
Total=63.75+45=$108.75
Therefore, the total dollar amount of coloured pencils sold is $108.75.

Question 2
64 is 40% of what number?
А
128
B
256
160
D
26
Answers
Answer:
answer is 160
Step-by-step explanation:
1. We assume, that the number 40 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 40, so we can write it down as 100%=40.
4. We know, that x% equals 64 of the output value, so we can write it down as x%=64.
5. Now we have two simple equations:
1) 100%=40
2) x%=64
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=40/64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 64 is what percent of 40
100%/x%=40/64
(100/x)*x=(40/64)*x
100=0.625*x
100/0.625=x
160=x
x=160
now we have:
64 is 40% 160

you pay 9.70 for 2.5 pounds of roasted peanuts. You buy 1.4 pounds of almonds for 8.55 per pound.
How much less do roasted peanuts cost per pound than almonds?
How much more do you spend on almonds than on roasted peanuts.
Answers
$9.70 / 2.5lbs = $3.88 / pound of roasted peanuts.
$8.55 * 1.4lbs = $11.97 / 1.4 pounds of almonds
$8.55 - $3.88 = $4.67.
Roasted peanuts cost $4.67 less per pound than almonds.
$11.97 - $9.70 = $2.27
You spend $2.27 more on almonds than you do roasted peanuts.

sara says. "if you subtract 14 from my number and multiply the difference by -4, the result is -80." What is Sara's number?
Answers
Answer:
34
Step-by-step explanation:
We can solve this equation by giving Sara's number a variable.
Let it be x.
Then we solve by simply interpreting the problem step by step.
"If you subtract 14 from my number..."
x - 14
"...and multiply the different by -4..."
-4(x-14)
"...the result is -80"
-4(x-14) = -80
Now that we have our equation, we can solve for x.
1.) Use distributive property to expand.
-4x + 56 = -80
2.) Subtract 56 from both sides
-4x = -136
3.) Divide by -4
x = 34
Sara's number is 34
Using distributive property to expand, it is found that Sara's number is; 34
What is distributive property?The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is
A(B + C) = AB + AC
This property is known by distributive law and applies to subtraction also.
We need to solve this equation by giving Sara's number a variable.
Let the Sara's number a variable be x.
Then we solve by simply interpreting "If you subtract 14 from my number..." means
x - 14
Then "...and multiply the different by -4..." means -4(x-14)
"...the result is -80"
-4(x-14) = -80
Now that we have our equation,
1.) Use distributive property to expand;
-4x + 56 = -80
Subtract 56 from both sides;
-4x = -136
Now Divide by -4
x = 34
Hence, Sara's number is; 34

What is the equation of the line that passes through (-3, -1) and has a slope of 3/5 ? Put your answer in slope-intercept form. A.y= 3/5x+4/5 B.y= 3/5x-4/5 C.y=-3/5x-4/5
Answers
Slope-intercept form: y = mx + b
m = the slope
b = y-intercept.
In this problem,
m = 3/5
b = ?
So far y = 3/5x + b
Let's plug the point (-3, -1) into our slope equation.
-1 = 3/5(-3) + b
Simplify the right side.
-1 = -9/5 + b
Add 9/5 to both sides.
4/5 = b
The equation is: y = 3/5x + 4/5
Answer choice A is correct.
