Write an equation of the line that passes through the given point an satisfies the given condition.
(-3,-5); parallel to y = -4x + 1
-6 = -1/2(9) + B
-6 = 4.5 + B
-6--4.5 = B
-1.5 = B
B= -1.5
y=-1/2x - 1.5
y=-1/2(9) - 1.5
y= -4.5-1.5
y=-6
what is 3n-22= -20
Answer:
n = 2/3
Step-by-step explanation:
3n - 22 = -20
Add 22 to both sides
-20 + 22 = 2
3n = 2
Divide both sides by 3
2 / 3 = 2/3
n = 2/3
Let me know if I've done something wrong :)
Answer:
[tex]n = \frac{2}{3}[/tex]
Step-by-step explanation:
Add 22 to each side, so it now looks like this: 3n = 2Divide each side by 3 to cancel out the 3 next to n. It should now look like this: [tex]n = \frac{2}{3}[/tex]I hope this helps!
Find the 10th term of the sequence defined by the given rule. Assume that the domain of each function is the set of whole numbers greater than 0.
f(1) = 8, f(n) = f(n − 1) + 15
The 10th term is
Answer:
[tex]87.[/tex]
Step-by-step explanation:
[tex]f(1) = 8, f(n) = f(n − 1) + 15 \\ The \: 10th \: term \: is \: \\ 8(10 − 1) + 15 = 72 + 15 = 87.[/tex]

Mrs. Potter was going through her Halloween candy to see which kind she would bring to school. She sorted using decimal values. .17 of her 100 pieces were black licorice. .42 were m&m's. .12 were skittles. .09 were smarties. .14 were lollipops and .06 were gum drops. Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Answer:
23%
Step-by-step explanation:
She sorted using decimal values.
We convert the decimals to percent
.17 of her 100 pieces were black licorice.
.17 = 0.17 × 100 = 17%
.42 were m&m = 0.42 × 100 = 42%
.12 were skittles. = 0.12 × 100= 12%
.09 were smarties = 0.09 × 100= 9%
.14 were lollipops = 0.14 × 100 = 14 %
.06 were gum drops. = 0.06 × 100= 6 %
Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Licorice = 17%
Gum drops = 6%
The percent of her candy that she brought to school = 17% + 6%
= 23%
The percent of her candy that she brought to school is 23%

Mr. Carter is building a circular fire pit in his backyard. The diameter of the fire pit is 6 feet and he will fill the interior with gravel covering 5/6 of the area. How much gravel will he need?
A. 23.55 sq. ft.
B. 28.26 sq. ft.
C. 94.2 sq. ft.
D. 113.04 sq. ft.
Answer:
23.55
Step-by-step explanation:
To calculate the area I did the following equation
area = 3.14 (r) (r)
area = 3.14 (3) (3)
area = 28.26
The area is 28.26 but the question is asking how much gravel would be needed to fill 5/6 of the area.
The equation for 5/6 out of 28.26 is
28.26 (5/6) = 23.55
So the final answer is (a.) 23.55 sq. ft.

y=-2x + 1
O y = 2x +1
O y = -2x - 1
O y = 2x-1
what is the missing value
Answer:
Plug in what you are given for y then solve for x:
[tex]-2 + 2 = -3(x - 4)\\\\0 = -3(x - 4)\\\\0 = -3x + 12\\\\-12 = -3x\\\\4 = x[/tex]
The missing value would be 4.
