8n - 7 = -5(-3n - 7)
Solve Multi-Step equation.
Please explain how you i can understand too!
Answer:
n=-6
Step-by-step explanation:
8n-7=-5(-3n-7)
Multiply -5 to -3n and -7
8n-7= 15n+35
Bring 8n to the other side by subracting it from 15n
-7=7n+35
Subtract 35 from both sides
-42=7n
Divide both sides by 7
n=-6

I only did the top part please I beg you help me
Answer:
I put 4, 5, & 6 in order in the photos.
7-8-9 are all linear functions which are written in the y=ax+b format, the ones I put in bold are the equations and I listed the values just in case I'm not sure how your teacher makes you write them.
7.
-0.6=a(-3)+b
0.2=a(1)+b
1.4=a(7)+b
a=0.2,b=0
y=0.2x
8.
-10=a(-5)+b
-1=a(-2)+b
17=a(4)+b
b=5, a=3
y=3x+5
9.
8=a(-5)+b
2=a(-2)+b
-18=a(8)+b
b=-2, a=-2
y=-2x-2

For a basic subscription, a cable television provider charges an activation fee of $60, plus $125 per month. What linear function represents the total cost of basic cable subscription for t months? What is the total cost for two years of service?
y=125x+60
$310 for 2 months
$3060 for 2 years
Step-by-step explanation: let x be the number of months
y=125x+60
y=125(2)+60
y=310 dollars for two months
y=125(24)+60
y=3060 dollars for two years

Answer:
4x+9=x+15
x = 2
Step-by-step explanation:
Let's solve this equation I just made:
4x + 9 = x + 15
Subtract 9 from each side:
4x = x + 6
Subtract x from each side:
3x = 6
Divide each side by 3:
x = 2
Use the distributive property to simplify the expression -8(5 + 9). Show your work.

can anyone help me with this problem with a full explanation?? thank you
Answer:
15, 16, 17
Step-by-step explanation:
let the consecutive numbers be n , n + 1 , n+ 2 , then
n + n + 2 = 32 ( sum of first and third )
2n + 2 = 32 ( subtract 2 from both sides )
2n = 30 ( divide both sides by 2 )
n = 15
n + 1 = 15 + 1 = 16
n + 2 = 15 + 2 = 17
The 3 numbers are 15, 16, 17
Step-by-step explanation:
let the 1st and 2nd consecutive number be
x , x + 1 , x + 2
their sum = 32
so, x + x + 2 = 32
→ 2x + 2 = 32
→ 2x = 32 - 2 = 30
→ x = 30/2 = 15
so,
1st and 3rd consecutive number is
x = 15
x + 2 = 15 + 2 = 17
as they are consecutive number so 2nd number is 16
and a/q sum of 1st and 3rd number is 32
15 + 17 = 32

4) Allison practices her violin for at least 12 hours per week. She practices for three fourths of an hour each
session. If Allison has already practiced 3 hours this week, how many more sessions remain for her to meet
or exceed her weekly practice goal?
Answer:
12
Step-by-step explanation:
So, she practices 12 hrs per week, and already has practiced 3 hrs this week.
This means she has 9 hrs left to practice.
3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)
which is basically 9 / ( 3/4)
[tex]\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4} = \frac{9}{1} * \frac{4}{3} = \frac{36}{3} = 12[/tex]
She needs 12 more sessions.
if a= 2, b= -3 and c= 4 evaluate ab-bc
Answer:
ab - bc = 6
Step-by-step explanation:
COMPUTATION:
ab - bc = ?
(2 x -3) - (-3 x 4) = ?
(-6) - (-3 x 4) = ?
(-6) - (-12) = ?
-6 + 12 = 6

You bought a package of paper for $3 and some pencils for $2 each at the school store. You paid $15 for everything that you bought. How many pencils did you buy?
Answer:
6 pencils
Step-by-step explanation:
Total cost = paper * cost of a package + pencils * cost of a pencils
We bought 1 pack of paper at 3 dollars and p pencils at 2 dollars
15 = 1*3 + p*2
15 = 3+2p
Subtract 3 from each side
15-3 = 3+2p-3
12 = 2p
Divide by 2
12/2 = 2p/2
6 = p
b + 2 = -18 find what the letter b means
Answer:
b = -20
Step-by-step explanation:
b + 2 = -18
b = -20
Answer:
b= -20
Step-by-step explanation:
the first step is to subtract 2 from both sides of the equation.
b + 2 = -18
-2 -2
-------------------
the -2 and +2 cancel
b = -20

A class contributed $19.00 in quarters and dimes to a local homeless shelter. In
all there were 100 coins. How many were there of each kind.
Answer: 60 quarters and 40 dimes
Step-by-step explanation:
Step 1: Setup Coin Value and Coin Total Equation:
Coin Value Equation → 0.1d + 0.25q = $19.00 where d = dimes and q = quarters
Coin Total Equation → d + q = 100
Step 2: Rearrange Coin Total Equation in terms of dimes (d)
d = 100 - q ← Revised Coin Total Equation
Step 3: Plug in our Revised Coin Total Equation for d into our Coin Value Equation:
0.1(100 - q) + 0.25q = $19.00
0.1(100) - 0.1(q) + 0.25q = $19.00
10 - 0.1q + 0.25q = $19.00
10 + (0.25 - 0.1)q = $19.00
10 + 0.15q = $19.00
Step 4: Subtract 10 from each side of the equation to isolate q
10 - 10 + 0.15q = $19.00 - 10
0.15q = 9
Step 5: Divide each side of the equation by 0.15 to isolate q
0.15q/0.15 = 9/0.15
q = 60
Step 6: Using our value for q, Solve for d using our Coin Total Equation:
d + 60 = 100
Subtracting 60 from both sides, we get d + 60 - 60 = 100 - 60
d = 40
Summarizing our word problem, we see that 60 quarters and 40 dimes add up to $19.00

I need help for all of them. I don’t understand how to do anything of them and i’m really confused
Answer:
steps below
Step-by-step explanation:
1) f(x) = (-3ax⁴ + ax² +x) / (2x⁴ + x³ - ax² + 8x) ... degree of the denominator = degree of the numerator (-3a) / 2 = 5 / 4
-12a = 10
a = - 5/6
2) 3-n > n+ 10 ... degree of the denominator < degree of the numerator
2n < -7
n < - 3.5
The largest inter value is -4
3) f(x) = (x²+3x-4) / (2x²+7x-10)
f(2) = (2²+3*2-4) / (2*2²+7*2-10) = 6 / 12 = 1/2
x->∞ : divide x² both numerator and denominator, any number/ x -> 0
f(x) = (1 + 3/x - 4/x²) / (2 + 7/x - 10/x) = (1 + 0 - 0) / (2 + 0 - 0) = 1/2
[tex]\lim_{x \to \infty} f(x) = f(2)[/tex] = 1/2
