Answer:
y=1/4x-7; can't put graph on here
Step-by-step explanation:
m=y2-y1/x2-x1
m=-8+6/-4-4=-2/-8=1/4
put it in point-slope form with (4,-6) as the base
y-y1=m(x-x1)
y+6=1/4(x-4)
y+6=1/4x-1
y=1/4x-7
Joseph received a $20 gift card for downloading music. Each downloaded song costs $1.29. Explain how to write and solve an inequality that can be used to determine the number of songs that he can purchase.
Interpret the solution.
Answer:
Step-by-step explanation:
Answer:
Let x be the number of songs downloaded.
Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs, or 1.29x.
This cannot be more than 20, so we set this less than or equal to 20:
1.29x ≤ 20.
To solve this, we divide both sides by 1.29:
≤ ;
x ≤15.5.
We cannot download half of a song, so we round this down to 15 (although the number rounds up mathematically, he would not have enough money to download 16 songs). This means he can download at most 15 songs.
Step-by-step explanation:
if you want the sample response then here: If x represents the number of downloads, you can write the inequality 1.29x ≤ 20. Solving the inequality, you find that x is less than or equal to about 15.5. Since he can’t download part of a song, Joseph can download 15 or fewer songs.

Solve the following inequality for n. Write your answer in simplest form.
1+4(-6n-4)<10n+4-n
Answer
n>- 19/33
1 Simplify 10n+4-n10n+4−n to 9n+49n+4.
1+4(-6n-4)<9n+41+4(−6n−4)<9n+4
2 Expand.
1-24n-16<9n+41−24n−16<9n+4
3 Simplify 1-24n-161−24n−16 to -24n-15−24n−15.
-24n-15<9n+4−24n−15<9n+4
4 Add 24n24n to both sides.
-15<9n+4+24n−15<9n+4+24n
5 Simplify 9n+4+24n9n+4+24n to 33n+433n+4.
-15<33n+4−15<33n+4
6 Subtract 44 from both sides.
-15-4<33n−15−4<33n
7 Simplify -15-4−15−4 to -19−19.
-19<33n−19<33n
8 Divide both sides by 3333.
-\frac{19}{33}<n−

A wheel has a radius of 13”; calculate the circumference.
Answer:
81.71"
Step-by-step explanation:
Circumference = 2*pi*radius
pi = 22/7
radius = 13
Circumference = 2*22/7*13 = 44*13 / 7 = 572/7 = 81.71"
Find the circumference a circle with the diameter AB
A (-8,4) and B (4,-1)
Answer:
C = 13π ≈ 40.82 units
Step-by-step explanation:
C = 2 r π = d π
AB = [tex]\sqrt{(-8-4)^2 +(4+1)^2}[/tex] = 13 units
C = 13π ≈ 40.82 units ( π ≈ 3.14 )

help, thank you so much!
Answer:
-2
Step-by-step explanation:
The average rate of change over [a, b] is simply the slope of the function over [a, b] because:
[tex]let\:g(x)=f'(x)\\\frac{\int\limits^b_a {g(x)} \, dx }{b-a} = \frac{f(b)-f(a)}{b-a}[/tex]
We have to find the avg ROC over [-3, 1] so the slope over the interval is
[tex]\frac{f(1)-f(-3)}{1-(-3)} = \frac{-6 - 2}{4} = \frac{-8}{4} = -2[/tex]

write 600 as a product of a prime factor give your answer in index form
Answer:This is problems on common factors.
(a) 600 = 2 × 2 × 2 × 3 × 5 × 5
= 2³ˣ 3 ˣ 5²
(b) The highest common factors could be calculated using factors methods and the divisional methods.
Here we go.
(i) 600 = 2³ ˣ 3 ˣ 5²
1050 = 2 ˣ 3 ˣ 5² ˣ 7, the highest common factor HCF will be
HCT = 2 ˣ 3 ˣ 5²
= 150.
The divisional methods.
600) 1050 ( 1
- 600
------
450 ) 600 ( 1
- 450
------
150 ) 450 ( 3
- 450
------
000
So the answer is 150, the principle is that you continue to divide and subtract until you arrive at zero.
Answer = 150

Triangle A″B″C″ is formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin. Which equation explains the relationship between segment AB and segment A double prime B double prime? coordinate plane with triangle ABC at A negative 3 comma 3, B 1 comma negative 3, and C negative 3 comma negative 3 segment A double prime B double prime = segment AB over 2 segment AB = segment A double prime B double prime over 2 segment AB over segment A double prime B double prime = one half segment A double prime B double prime over segment AB = 2
Answer:
A. segment A double prime B double prime = segment AB over 2Step-by-step explanation:
Triangle ABC with coordinates of:
A = (-3, 3), B = (1, -3), C = (-3, -3)Translation (x + 2, y + 0), coordinates will be:
A' = (-1, 3), B = ( 3, -3), C = (-1, -3)Dilation by a scale factor of 1/2 from the origin, coordinates will be:
A'' = (-0.5, 1.5), B'' = (1.5, -1.5), C= (-0.5, -1.5)Let's find the length of AB and A''B'' using distance formula
d = √(x2-x1)² + (y2 - y1)²AB = √(1-(-3))² + (-3 -3)² = √4²+6² = √16+36 = √52 = 2√13A''B'' = √(1.5 - (-0.5)) + (-1.5 - 1.5)² = √2²+3² = √13We see that
AB = 2A''B''Now the answer options:
A. segment A double prime B double prime = segment AB over 2
CorrectB. segment AB = segment A double prime B double prime over 2
Incorrect. Should be AB = A''B''*2C. segment AB over segment A double prime B double prime = one half
Incorrect. Should be AB/A''B'' = 2D. segment A double prime B double prime over segment AB = 2
Incorrect. Should be A''B''/AB = 1/2Answer:
A. segment A double prime B double prime = segment AB over 2
