Answer:
(a) y = 1/4x - 4
(b) y = -4x + 17
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
(a)
Parallel lines have the same slope but different y-intercepts.
m = 1/4x
y = 1/4x + b
-2 = 1/4(8) + b
-2 = 2 + b
b = -4
y = 1/4x - 4
(b)
Perpendicular lines have the negative reciprocal slope.
m = -4
y = -4x + b
1 = -4(4) + b
1 = -16 + b
b = 17
y = -4x + 17
Which statement correctly describes this expression 2m3-11 A. Twice the cube of the number subtracted from 11 B.the difference of twice a number and 11 cubes
A number is :
[tex]m[/tex]
_________________________________
Cube of it equals :
[tex] {m}^{3} [/tex]
_________________________________
Twice the cube equals :
[tex]2 {m}^{3} [/tex]
_________________________________
Subtract it from 11 equals :
[tex]2 {m}^{3} - 11 [/tex]
Which is the expression we have.

6. Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass. How fast are they traveling?
They traveling at -0.37 m.s^-1 along the direction of 55 kg kid.
You must solve for s.
-8s + 16 = 56
Answer:
s= -5
Step-by-step explanation:
-8s + 16 = 56
Subtract 16 from both sides of the =, as this will cancel the + 16
-8s = 40
Divide both sides by -8, as this will cancel out the -8 beside the s
s = -5
You have $13 to spend on an Uber. The driver charges $0.35 per mile plus a $1 fee for the trip. At the end of the trip, you have $0.80 left. How many miles did
you go?
Answer:
32 miles
Explanation
$13 the money you have -$0.80 the money left
=12.20 the money you spent- $1 fee for the trip
=$11.20÷$0.35 per mile
=32 miles
A bird leaves its nest and travels 15 miles per hour downwind for x hours. On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
a. What is the distance of the entire trip?
miles
b. How long does the entire trip take?
_hours
_minutes and
_seconds
Answer:
A)
10 miles.
B)
0 hours, 40 minutes, and 0 seconds.
Step-by-step explanation:
Remember that distance is given by the formula:
[tex]d=st[/tex]
Where d is the distance, s is the speed, and t is the time.
We know that the bird leaves its nest and travels 15 miles per hour for x hours. So, let's substitute 15 for s and x for t:
[tex]d=15x[/tex]
On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
Since this is the return trip, the distance d remains the same. We know that the bird travels 3 miles per hour slower, so it's speed is 15-3 or 12 miles per hour.
However, after x hours, it still has 2 miles left until reaching the destination. So, we will subtract 2 from d. This gives us the equation:
[tex]d-2=12x[/tex]
We can solve this using substitution. Since we already know that d is 15x. Substitute:
[tex]15x-2=12x[/tex]
Solve for x. Subtract 12x from both sides:
[tex]3x-2=0[/tex]
Add 2 to both sides:
[tex]3x=2[/tex]
Divide both sides by 3:
[tex]x=2/3[/tex]
Therefore, the bird traveled for a total of 2/3 hours or 40 minutes.
And the distance the bird traveled is:
[tex]d=15x[/tex]
Substitute 2/3 for x to get:
[tex]d=15(2/3)=30/3=10\text{ miles}[/tex]
And we're done!

g(x) = 2 log(x - 1)
what is the inverse
Answer:
[tex]g^{-1}(x)=1+10^{x/2}[/tex]
Step-by-step explanation:
Inverse Function
Let's call:
[tex]y=2 log(x-1)[/tex]
Divide by 2:
[tex]y/2=log(x-1)[/tex]
Assuming the base of the log is 10, apply exponential base 10:
[tex]10^{y/2}=x-1[/tex]
Solving for x:
[tex]x=1+10^{y/2}[/tex]
Swap variables:
[tex]y=1+10^{x/2}[/tex]
Calling this function the inverse:
[tex]\boxed{g^{-1}(x)=1+10^{x/2}}[/tex]

The same amount of principal is invested in different accounts earning the same interest rate.
Which of the following accounts would have the greatest accumulated value at the end of one year?
A.An account eaming no interest
B.An account eaming simple interest
C.An account eaming interest compounded annually
D.An account earming interest compounded daily
Answer:
D.An account earming interest compounded daily
Step-by-step explanation:
An account earning interest compounded daily would have accumulated the greatest value at the end of the year.
Compound interest is interest on interest. In compound interest, the interest is calculated on the principal and interest accrued. This makes the value highest. For the account compounded daily, the interest on interest is taken every day. It has a power of 365. For compound interest accrued annually, the interest compounded yearly. Simple interest is basically on the principal.Answer: D! On edge 2021

Step-by-step explanation:
Simple Interest
Simple interest represents a fee you pay on a loan or income you earn on deposits.
When borrowing money: You must repay the amount you borrowed and make extra payments for interest, which represents the cost of borrowing.
When lending money: You typically set a rate and earn interest income in exchange for making your money available to other people.
When depositing money: Interest-bearing accounts such as savings accounts pay interest income because you are making money available to the bank to lend to others.
How to Calculate It
In the following example, the term "simple" means you're working with the simplest way of calculating interest. Once you understand how to calculate simple interest, you can move on to other calculations, such as annual percentage yield (APY), annual percentage rate (APR), and compound interest.
