Step-by-step explanation:
For number 8, to start,:
[tex]\frac{x}{4}[/tex] - 1 = 1
the first step is to add 1 to both sides of the equation; then, simplify.
[tex]\frac{x}{4}[/tex] - 1 = 1
+1 +1
----------------
next, the -1 and +1 will cancel.
[tex]\frac{x}{4}[/tex] = 2
the last step is to multiply both sides of the equation by 4.
4 · [tex]\frac{x}{4}[/tex] = 2 · 4
simplify; the 4s cancel out on the left side.
x = 8
**************************************************
For number 9, :
9 = 6 + [tex]\frac{x}{7}[/tex]
like in number 8, the first step is to subtract 6 from both sides of the equation; also, a helpful tip you can use is move the 9 to the right side; speaking personally, it often helps make things visually easier to work out. you would then rewrite the equation like: 6 + [tex]\frac{x}{7}[/tex] = 9
6 + [tex]\frac{x}{7}[/tex] = 9
now, we'd subtract 6 from both sides.
6 + [tex]\frac{x}{7}[/tex] = 9
-6 -6
-----------------
next, the 6 and -6 will cancel.
[tex]\frac{x}{7}[/tex] = 3
the last step is to multiply both sides of the equation by 7.
7 · [tex]\frac{x}{7}[/tex] = 3 · 7
simplify; the 7s cancel out on the left side.
x = 21

Answer:
6. [tex]\pi = \frac{C}{2r}[/tex]
7. Translation
Step-by-step explanation:
6: To solve for π means to isolate it on one side.
Step 1: Divide both sides by 2r.
[tex]\frac{C}{2r} = \frac{2\pi r}{2r}[/tex] [tex]\pi = \frac{C}{2r}[/tex]Therefore, π = circumference over twice the radius, or circumference over diameter.
7: #7 is a translation because each point is moving vertically 3 units and horizontally 1 unit (3 units up and 1 unit to the right). If it were a reflection, we'd be able to spot a line of reflection, but there isn't any here. Also, if it were a rotation, the triangle would change the way its angled, and it'd be in a different quadrant
Therefore, this is a translation.

Step-by-step explanation:
distribute first 10-2.5x+12=21-10x-28
Simplify(add the numbers) 22-2.5x=-7-10x
move the variable to the left side 22-2.5x+10x=-7
move the constant to the right side -2.5x+10x=-7-22
simplify like terms 7.5x=-29

Write the equation of the line in fully simplified slope/intercept form
Answers
Answer:
y = m x + b standard form for straight line
m = (y2 - y1) / (x2 - x1)
When y2 = 12, x = -6
when y = 0, x = -2
m = (12 - 0) / (-6 - (-2)) = -3
so y = -3 x + b
Also, when x = 0, y = -6
Our equation is
y = -3 x - 6
As a check try x = -2
y = (-3 * -2) + (-6) = 0 as the graph shows

How much she tipped:
$25 - $21.18 = $3.82
To find the percentage, you can put this tip over the what she paid for the pizza.

Answers
Assuming you meant to type h(x)=-4x+1
Answer:
[tex]f(x)=-\frac{1}{4}x+\frac{1}{4}[/tex]
Step-by-step explanation:
We know that, because [tex]h(x)[/tex] is the inverse of [tex]f(x)[/tex], that [tex]h(f(x))=x[/tex], so [tex]-4f(x)+1=x[/tex].
Aha! We can solve for [tex]f(x)[/tex]!
We subtract [tex]1[/tex] from both sides to get [tex]-4f(x)=x-1[/tex].
Finally, we divide both sides by [tex]-4[/tex] to get [tex]\boxed{f(x)=-\frac{1}{4}x+\frac{1}{4}}[/tex].

Answers
For the three types of candies, we will write a slope-intercept form equation. We know what m (slope) is for each equation, and there is no y-intercept because there is no starting point.
Equations:
Mints: y=.96x
Chocolates: y=4.70x
Lollipops: y=.07x
Using the given information, we can use the equations in function form. We know what x (input) is for all three types of candy, and that will give us y (output), which is the total for that candy type.
Solving:
Mints: y=.96(.75)
Chocolates: y=4.70(1.5)
Lollipops: y=.07(15)
We just input our information into the equations. Using logic, we know that we will have to multiply the cost of the candy by the number of candies to get the total of the three types.
Totals:
Mints: y=.72
Chocolates: y=7.05
Lollipops: y=1.05.
*Recall that y=total cost of candy for each type.
Now, we just simply add the three costs up to get the total sum that the candy will cost:
.72+7.05+1.05=8.82
Therefore, all the candy will cost $8.82.
