- 4(y-2) = 12
What’s the value of x?
Explain
Answer:
There is no x, so I’ll find y
Step-by-step explanation:
-4(y-2)=12
Multiply -4 with y and -2
-4y+8=12
Then subtract 8 with its self and 12
-4y = 4
now divide both numbers with 4
y= -1

The parent function y = -2x^2+5 is translated down 12 units and left 8 units. What is the new equation in vertex form?
Answer:
y=-2(x+8)²-7
Step-by-step explanation:
Given: y=-2x²+5
After transformations: y=-2(x+8)²-7
Vertex would be (h,k) -> (-8,-7) instead of (0,5)

Answer:
Step-by-step explanation:
m∠ 1 = 180 - 117
m∠ 1 = 63
m∠2 = the same as m∠ 1
m∠2 = 63
m∠3 is also the same b/c of the same length of the "legs" of the triangle
m∠3 = 63

Determine whether the graphs of the given equations are parallel, perpendicular, or neither.
9514 1404 393
Answer:
(c) Perpendicular
Step-by-step explanation:
The slope is the coefficient of x in this slope-intercept form.
The slope of the first line is +1.
The slope of the second line is -1.
The product of the slopes is (1)(-1) = -1. When the product of slopes is -1 for two lines, those lines are perpendicular.

Trinity had $525.38 in a savings account at the beginning of the summer she wants to have at least $200 in the account by the end of the summer she withdraws $25 each week for food, clothes and movie tickets writing in a quality that represents triniti's situation. How many weeks can Trinity withdraw money from her account solve the inequality
Answer:
Trinity can withdraw $25 from her bank account for 13 weeks.
Step-by-step explanation:
If she wants to have at least $200 by the end of summer you need to subtract that much from what she has now. Which would be $325.38. Now you have to divide that number into 25, which should give you the number of week that money would last. That number is 13.0152, you don't need all those extra numbers so just use 13. No to check you work multiply 25 and 13. You get 325.
Tasneem has a sample of 12 bags of candy. She recorded the mass, in grams, of each bag. Her data is shown.
Answer:
the answer is D
Step-by-step explanation:
The Dot plot for Alia's Sample is plot D.
What is Dot plot?Based on the values of each point, a dot plot visually groups the number of data points in a data set. Similar to a histogram or probability distribution function, this provides a visual representation of the data distribution.
Tasneem has a sample of 12 bags of candy.
Now, the median for Tasneem sample space is
= (47.1 + 47.2)/ 2
= 47. 15
As, the median mass in A is 47.05, B is 47.1, in C is 47.1 and in D is 47.4.
Also, we know that the median mass for Alia's Sample is greater than Tasneem.
Thus, the correct plot is D.

To begin solving for the total cost of the paint that Ariana needs to buy, we first need to calculate the size of the walls and the ceiling that she is going to paint.
We begin by finding the size for the walls.
We use the formula to find the area of each wall.
We know that the walls are 10-foot squares.
10 x 10 = 100 Square Feet
Each wall will have an area of 100 square feet each, we know that there are 4 walls in the shed.
100 x 4 = 400 Square Feet of walls to paint total.
Now we know that the ceiling will have the same area as the walls.
10 x 10 = 100 Square Feet of ceiling to paint.
Now Ariana goes to the store and finds that a gallon of paint cover 350 square feet. Ariana needs to paint a total of 400 square feet of wall.
400 - 350 = 50 Square Feet remains.
We know that she needs to buy the paint in gallons, so this leaves Ariana with purchasing 2 gallons of Blue paint.
Now Ariana also wants to paint the ceiling white. We know that 1 gallon of White paint is more than enough to cover the ceiling, but she still needs to buy the gallon of paint.
Now we add up all the prices of the 3 gallons of paint.
$26.98 x 2 = $53.96 for Blue Paint
$26.98 x 1 = $26.98 for White Paint
Total cost = $80.94.
Now we know that the sales tax is 5.5% of the total price.
$80.94 x 0.055
Sales Tax = $4.45
Now we simply add the total cost to the sales tax.
$80.94 + 4.45
Total cost with sales tax = $85.39
Pls help me with this equation
Answer:
$340
Step-by-step explanation:
Let $p be the price yesterday.

Achilles ordered a pizza with 16 slices. Every hour, he ate half of the remaining slices. Let f(n) be the number of slices Achilles ate in the hour since he got home.
Consider we need to find f(n).
Given:
Achilles ordered a pizza with 16 slices.
Every hour, he ate half of the remaining slices.
To find:
The function f(n) that is the number of slices Achilles ate in the hour since he got home.
Solution:
Initial number of slices = 16
Every hour, he ate half of the remaining slices. So, the number slices Achilles ate in the hour since he got home are:
8, 4, 2, 1, ...
It is a geometric sequence with first term 8 and common ratio [tex]\dfrac{1}{2}[/tex].
The explicit formula for a geometric sequence is:
[tex]f(n)=ar^{n-1}[/tex]
Where, a is the first term and r is the common ratio.
Substituting [tex]a=8,r=\dfrac{1}{2}[/tex], we get
[tex]f(n)=8\left(\dfrac{1}{2}\right)^{n-1}[/tex]
Therefore, the function f(n) that is the number of slices Achilles ate in the hour since he got home is [tex]f(n)=8\left(\dfrac{1}{2}\right)^{n-1}[/tex].
