Answer:
x≤-8
Step-by-step explanation:
When solving 8x-8≤-72, first add 8 to both sides of the inequality.
This leaves you with 8x≤-64.
Divide both sides by 8: 8x/8 and -64/8
This leaves you with x≤-8 as your solution.

A major credit card company requires monthly payments equal to or greater than 8% of the total balance.A consumer has a credit card balance of $320. Write an inequality that represents acceptable payment amounts.
Answer:
320 x 0.08 = X
In the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.
Step-by-step explanation:
Given that a major credit card company requires monthly payments equal to or greater than 8% of the total balance, and a consumer has a credit card balance of $ 320, the following calculations must be performed to determine an inequality that represents acceptable payment amounts:
320 x 0.08 = X
25.6 = X
Thus, in the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.
Find the x-intercept of the following equation. Simplify your answer.
x + 6y = 9. Can someone pls help me?
Answer:
y intercept=3/2
Step-by-step explanation:
First of all, write it in slope intercept form
y=-1/6x+3/2
y=mx+b
b=y-intercept
y intercept=3/2
x+6y=9
y=0
x+6(0)=9
x=9
v) Find the perimeter of the rectangle whose length is 60m and breadth is 55m
vi) Find the perimeter of a square room with side equal to 8m each.
Answer:
Step-by-step explanation:
l = length
b = breadth
We know the length is twice the breadth, therefore l = 2b
We also know that the perimeter p = 60m and can also be expressed as a sum of its sides where p = l + l + b + b = 60 which simplified is:
60 = 2l + 2b
Now we have 2 variables, but thankfully we were given a ratio (l = 2b) relating the two. Substituting 2b in for l gives us:
60 = 2(2b) + 2b = 4b + 2b = 6b
60 = 6b
b = 10 m
Now that we know the breadth we can find the length:
l = 2b → l = 2(10) = 20 → l = 20 m
With a breadth of 10 m and a length of 20 m
Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and the area of the rug
Answer:
Width = 1/2h
Area = 1/4h²
Step-by-step explanation:
This is quite a vague question from you. Being asked to find the width and area of a particular shape, without being given dimensions.
However, I would try to solve it nonetheless.
From your question, you stated that the width of the rug is half its height, if so, then,
w = 1/2h
Again, you're being asked to find the area. Area of a kite is given as
Area = 1/2 * Width * Height and as such, we have
Area = 1/2 * 1/2h * h
Area = 1/4 * h²
All that you need to do now is substitute the value of h

Mr. Fisherman spent his weekend working in his yard. He had 1/6 of a bag of soil that he spread evenly among his 2 garden beds. How much soil did he put in each garden bed?
Answer:
1/12 per bag
Step-by-step explanation:
A Fisherman spent his weekend working on his farmland
He had 1/6 of a bag of soil
He spreads it evenly among his 2 garden beds
Therefore the soil in each garden bed can be calculated as follows
= 1/6 ÷ 2
= 1/6 × 1/2
= 1/12 per bag

Hayley is filling small cone-shaped cups with clay for an art project. Each cup has a height of 4 centimeters and a diameter of 1.5 centimeters. If Hayley has 25 cm³ of clay, how many cones can she fill? *need answer NOW*
Answer:
10.6 cones
Step-by-step explanation:
Given data
h= 4cm
d= 1.5cm
r= d/2= 0.75cm
The expression for the volume of a cone is
V= 1/3πr^2h
substitute
V= 1/3*3.142*(0.75)^2*4
V= 1/3*3.142*2.25
V=1/3*7.0695
V= 2.3565cm^3
Since the volume of 1 cone is 2.4cm^3
She can fill
=25/2.3565
=10.6 cones
About 10.6 cones
Drag each graph to the correct location on the table.
The points on the graphs represent relations. Classify these relations according to whether or not they are functions
Answer:
Functions: Second Graph
Not functions: first and third graph
Step-by-step explanation:
The first and third graph are not functions and the second graph is a function. Use the vertical line test. I'm 100% sure.
By the vertical line test, it's clear that graph first will not be a function, second will be a function and third will also not be a function.
What is the e-test?A vertical line test is a test to determine whether a given function is a function or not.
In the vertical line test, we draw a vertical line on every x's point if the line intersects with only a single value of corresponding y then it will be a function otherwise not.
In the first given function if we draw a vertical line at x = 2 then it gave different values corresponding to y hence, it will not a graph.
In the second given function by drawing a vertical line, it gave a single unique value so it will be a function.
In the third given function if we draw a vertical line at x = 1 and 2 then it gives different values corresponding to y hence, it will not be a graph.

2. An Evergreen Eagle flies about 13 meters in one second. How many kilometers could it fly in 20 minutes? *
Answer:
Evergreen Eagle can will fly 1.56 km in 20 minutes.
Step-by-step explanation:
Speed of Evergreen Eagle = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
= [tex]\frac{13}{1}[/tex]
= 13 meters per second
With this speed Eagle can fly the distance in 20 minutes Or 120 seconds
= Speed × Time
= 13 × 120
= 1560 meters
Since, 1000 meters = 1 Km
1 meter = [tex]\frac{1}{1000}[/tex] km
Therefore, 1560 meters = [tex]\frac{1560}{1000}[/tex]
= 1.56 km
Therefore, Evergreen Eagle can will fly 1.56 km in 20 minutes.

Use the AA similarity Postulate to prove the diagram has two similar
triangles. Name the triangles correspondingly.
Answer:
Triangle PRT is similar to triangle SRQ
Step-by-step explanation:
AA similarity Postulate :If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
one angle is already given : angle RPT congruent to angle RSQ
The other is : angle TRP congruent to angle SRQ (both triangles share the same angle)
Triangle PRT is similar to triangle SRQ (AA postulate)
The 1st 3 terms of an A.P., a, a+d, and a+2d, are the same as the 1st 3 terms of a G.P.( a is not equal to 0). Show that this is only possible if r=1 and d=0
Answer:
See Below.
Step-by-step explanation:
The first three terms of an A.P is equivalent to the first three terms of a G.P.
We want to show that this is only possible if r = 1 and d = 0.
If a is the initial term and d is the common difference, the A.P. will be:
[tex]a, a+d, \text{ and } a+2d[/tex]
Likewise, for the G.P., if a is the initial term (and it does not equal 0) and r is the common ratio, then our sequence is:
[tex]a, ar,\text{ and } ar^2[/tex]
The second and third terms must be equivalent. Thus:
[tex]a+d=ar\text{ and } a+2d=ar^2[/tex]
We can cancel the d. Multiply the first equation by -2:
[tex]-2a-2d=-2ar[/tex]
We can now add this to the second equation:
[tex](a+2d)+(-2a-2d)=(ar^2)+(-2ar)[/tex]
Simplify:
[tex]-a=ar^2-2ar[/tex]
Now, we can divide both sides by a (we can do this since a is not 0):
[tex]-1=r^2-2r[/tex]
So:
[tex]r^2-2r+1=0[/tex]
Factor:
[tex](r-1)^2=0[/tex]
Thus:
[tex]r=1[/tex]
The first equation tells us that:
[tex]a+d=ar[/tex]
Therefore:
[tex]a+d=a(1)\Rightarrow a+d=a[/tex]
Hence:
[tex]d=0[/tex]
