Which equation represents a line that is perpendicular to y=3x−4?
Answer:
- 1/3x + 2Step-by-step explanation:
Given line:
y = 3x - 4Perpendicular lines have negative-reciprocal slopes:
m₁*m₂ = - 1Since m₁ = 3, we can find m₂:
3*m₂ = - 1m₂ = - 1/3Given choices:
-1/3x + 2 or 1/3x - 4Correct choice is the first one
Katrina wants to earn at least $600 this week in commission. What is the minimum amount she needs to sell in order to earn $600 if she earns a 7.5% commission on everything she sells? Round your answer to the nearest dollar if necessary.
__________
Answer:
$8000
Step-by-step explanation:
For every $1000 Katrina sells, she earns $75. This is becuase when we multiply what she sold by her commision price, we get what she made
If we want to find how much she needs to make to earn $600, we can divide 600 by 75. This gives us 8. So, she will need to sell $8000 in order to earn $600

1. You have two pieces of tape of 56 metres and 56 metres in length. If you connect both pieces together end-to-end, how long is your new piece of tape?
Answer:
Step-by-step explanation:
If the two pieces of tape are truly placed end-to-end, there will be no tape at the joint to connect the two pieces. In the real world, one of the 56 m pieces will have to overlap one end of the other piece to make up a single new piece of tape whose length must be a little less than 2(56 m), or a lilttle less than 112 m. There is no one specific correct answer because the experimenters vary in how much tape overlap to allow.
The new tape would measure 112m after the two fragments are joined.
What is addition?Addition is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division. The addition of two whole numbers results in the total amount or sum of those values combined.
Given:
A piece of tape 56 m long and we are to add another 56 m
Thus the sum of these two tapes is equal to 56+56=112 m
Hence, the new tape is 112m long.

Annelise buys a car that is one year old for $13600.
The value of this car has reduced by 15% of the value when it was new.
Calculate the value of the car when it was new.
Answer:

Initial value is x, current value is $13600, price reduction by 15%.
x - 15% = 13600x - 0.15x = 136000.85x = 13600x = 13600/0.85x = 16000
Ricardo borrows $1,850 for 10 months at an interest rate of 12.25%. What amount will
he have paid back at the end of the loan period?
9514 1404 393
Answer:
$2038.85
Step-by-step explanation:
The value of the loan at that point is given by ...
A = P(1 +rt) . . . . . Principal P, rate r, time t (years)
A = $1850(1 + 0.1225·(10/12)) = $2038.85
Ricardo will have paid back $2038.85 at the end of the loan period.
_____
Additional comment
We assume that the loan accrues simple interest and that the amount due is the sum of principal and interest at the end of the loan period.
The question is not specific as to whether interest compounds, or whether intermediate (monthly) payments are made. There are many possible ways the loan could be repaid, generally involving different amounts for the different terms.

Who walks at a faster rate: someone who walks 60 feet in 10 sec or someone who takes 5 sec to walk 25 feet?
Answer:
60 ft in 10 seconds.
Step-by-step explanation:
Theoretically, if the 5 second dude were to walk ten seconds, they'd only walk 50. (25 x 2 = 50, therefore 60 feet in 10 seconds is faster)
Answer:
I think it's the guy who walks 60 feet in 10 seconds
Step-by-step explanation:
Since the other guy walks 25 feet in 5 seconds, we can simply double the seconds to get 10 seconds and 50 feet.
So the first guy walks 60ft/sec and the second one walks 50 ft/sec

THEN c. If a || band line c is parallel to line a, then line b and c are?
Answer: parallel
Step-by-step explanation:
For two lines to be parallel they must have the same slope.
Because a is parallel to b they must have the same slope. Let's call that slope x.
Because c is parallel to b they must have the same slope. Because the slope of b is x, the slope of c must be x.
Because the slope of both a and c are x, they must be parallel.

when identifying the rate lf change using a graph check ___ over __
Answer: rise over run
======================================================
Explanation:
The rate of change is the same as slope. Slope is often defined as the ratio of rise over run.
In other words, slope = rise/run.
For instance, a slope of 2/3 means we go up 2 and to the right 3 units.
Another example: slope = -1/5 means we go down 1 and to the right 5.
The term "rise" indicates a change in y. The run is the change in x. If the rise is positive, then you go up. Negative rise values mean that you go down. The run always moves to the right.
On the first down the team returned the ball to the 30 yard line, then they ran the 42 yard line for a gain. which number represents the change? (number line is on pic)

The number which represents the gain as per the question is +12. Hence, option "d" is correct.
What are arithmetic operations?The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.
They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.
As per the information given in the question,
Firstly, the team returned the ball to the 30-yard line.
Then, hey ran to the 42-yard line for a gain.
Then, the number that shows the change will be,
= 42 - 30
= +12, there is gain of +12.

One solution to the system of equations is (4,4).
The other solution to the system of equations is
Answer:
(-4,-4)
Step-by-step explanation:
Since y=x,plug in x for y in equation 2
x²+x²=32
2x²=32
x²=16
