Answer:
y = -⁶/₅x - 8Step-by-step explanation:
The slope-intercept form of equation is: y = mx + b
where m is slope and b is y-intercept
If line y=ax+b passes through point (x₀,y₀) that means
that the equation y₀=ax₀+b is true
(-5, -2) ⇒ x=-5, y=-2
m = -⁶/₅
So:
-2 = -⁶/₅ (-5) + b
-2 = 6 + b
b = -8
Therefore equation in slope-intercept form:
y = -⁶/₅x - 8

Does (3, 10) make the inequality y > 2x + 2 true?
Answer:
Yes, it makes it true
Step-by-step explanation:
Plug in 3 and 10 as x and y into the inequality:
y > 2x + 2
10 > 2(3) + 2
10 > 6 + 2
10 > 8
Since 10 is bigger than 8, this inequality is true.
So, (3, 10) makes the inequality true.

If the measure of GH is 30° and the radius is 6 meters, what is the arc length of GH?
Answer:
The length of the arc GH is approximately 3.14 meters (or π)
Step-by-step explanation:
The length of an arc whose measure equals the measure of the central angle Ф and the radius of the circle r is:
L = (Ф ÷ 360°) × 2π rLet us solve the question using the rule above
∵ The measure of arc GH is 30°
∴ Ф = 30°
∵ The radius is 6 meters
∴ r = 6 meters
→ Substitute them in the rule above
∵ L = (30° ÷ 360°) × 2π × 6
∴ L = [tex]\frac{1}{12}[/tex] × 12π
∴ L = π
→ Use π ≈ 3.14
∴ L ≈ 3.14
∴ The length of the arc GH is approximately 3.14 meters (or π)
Using the number line to help you, decide which fraction is larger, or if they are equal: four/fifths or seven/tenths. Label each fraction on the number line.
Answer:
4/5 is bigger than 7/10
Step-by-step explanation:
Just divide them each
4/5 = .8
7/10 = .7
Umm... your going to have to put those on the number line yourself sorry
Answer: 4/5. 4/5 can also mean 8/10. 8/10 is greater than 7/10. I do not know how to label the fraction on the number line if it is a picture so hopefully you can do that.
A Web music store offers two versions of a popular song. The size of the standard version is 2.8 megabytes (MB). The size of the high-quality version is 4.1
MB. Yesterday, there were 1600 downloads of the song, for a total download size of 5624 MB. How many downloads of the high-quality version were
there?
Number of high-quality version downloads:
Answer:
Number of high quality version downloads = 880
Step-by-step explanation:
Let,
x be the number of standard version songs downloaded
y be the number of high quality version songs downloaded
According to given statement,
x+y=1600 Eqn 1
2.8x+4.1y=5624 Eqn 2
Multiplying Eqn 1 by 2.8 to eliminate x
2.8(x+y=1600)
2.8x+2.8y=4480 Eqn 3
Subtracting Eqn 3 from Eqn 2
(2.8x+4.1y)-(2.8x+2.8y)=5624-4480
2.8x+4.1y-2.8x-2.8y=1144
1.3y=1144
Dividing both sides by 1.3
[tex]\frac{1.3y}{1.3}=\frac{1144}{1.3}\\y=880[/tex]
Hence,
Number of high quality version downloads = 880

Amanda buys 4 tickets to the baseball game for $24 each. Which equation
shows the closest estimate of the total amount Amanda spends?
Which equation shows the closest estimate of the total amount Amanda spends
Answer:
$96
Step-by-step explanation:
Given that,
The total number of tickets = 4
Cost of each baseball = $24
We need to find the equation that shows the closest estimate of the total amount Amanda spends.
Total cost = No. of tickets × Cost of each baseball
= 4×24
= $96
Hence, the total cost is $96.
Two angles form a linear pair. One angle measures (10x - 63). The other angle measures (8x)". What is the value of the larger
angle?
O 180
O 72
O 135
O 108
Answer:
108 degrees
Step-by-step explanation:
Given
Let the angles be A and B
[tex]A = 10x - 63[/tex]
[tex]B = 8x[/tex]
Required
Find the larger angle
If both angles form linear pair, then the following relationship exist:
[tex]A + B = 180[/tex]
Substitute values for A and B
[tex]10x - 63 + 8x = 180[/tex]
Collect Like Terms
[tex]10x + 8x = 180 + 63[/tex]
[tex]18x = 243[/tex]
Solve for x
[tex]x = \frac{243}{18}[/tex]
[tex]x = 13.5[/tex]
Substitute 13.5 for x in
[tex]A = 10x - 63[/tex]
[tex]B = 8x[/tex]
[tex]A= 10 * 13.5 - 63[/tex]
[tex]A= 135 - 63[/tex]
[tex]A= 72[/tex]
[tex]B = 8 * 13.5[/tex]
[tex]B = 108[/tex]
Hence, the larger angle measures 108

How many solutions does the following equation have ?
- 32 +9 – 2x = -12 – 5x
Choose 1 answer:
No solutions
B
Exactly one solution
С
Infinitely many solutions
Answer:Exactly one solution.
Step-by-step explanation:
- 32 +9 – 2x = -12 – 5x
1.Add numbers
-23 - 2x= -12-5x
2.Rearrange terms
-2x - 23 = -12 - 5x
3. Rearrange terms
-2x - 23 = -5x-12
4. Add 23 to both sides of the equation
-2x-23+23= -5x-12+23
5.Simplify
-2x= -5x+11
6.Add 5x to both sides of the equation
-2x+5x=-5x+11+5x
7.Simplify
3x=11
8.Divide both sides of the equation by the same factor
[tex]\frac{3x}{3}[/tex] = [tex]\frac{11}{3}[/tex]
9.Simplify and Solution
x= [tex]\frac{11}{3}[/tex]
Mary decreased her time for the mile walk from 30 minutes to 24 minutes. What was the percent of decrease?
Answer:
20%
Step-by-step explanation:
Formula:
((GreaterTime-LeastTime)/Greatertime)x100= Percentage of Decrease.
((30-24)/30)*100=percent of decrease.
(6/30)*100=percent of decrease.
0.2*100= percent of decrease.
20%.

One health club charges a $44 sign-up fee and $30 per month. Another health club charges a $99 sign-up fee and $25 per month. What number of months will the cost be the same? Write an equation or inequality then solve it. Provide work
Step-by-step explanation:
Let x be the number of months for the 2 health clubs to have the same cost.
We have $44 + $30x = $99 + $25x.
Therefore $5x = $55 and x = 11.
The number of months is 11.
