<span>y=4x−1;y=2x−5
Step: Solve y=4x−1 for y:
Step: Substitute 4x−1 for y in y=2x−5:
y=2x−5
4x−1=2x−5
4x−1+−2x=2x−5+−2x(Add -2x to both sides)
2x−1=−5
2x−1+1=−5+1(Add 1 to both sides)
2x=−4
2x/2=−4/2(Divide both sides by 2)
x=−2
Step: Substitute−2 for x in y=4x−1:
y=4x−1
y=(4)(−2)−1
y=−9(Simplify both sides of the equation)
<u>Answer:</u>y=−9 and x=−2</span>
Answer:
The money after 3 years is $5819.8735
Step-by-step explanation:
We are given
monthly payment =$75
so, P=75
annuity that earns 48% APR
so, r=48%
Since, it is compounded monthly
so,
%
i=0.04

now, we can use annuity formula
![FV=P[\frac{(1+i)^n-1}{i} ]](https://tex.z-dn.net/?f=FV%3DP%5B%5Cfrac%7B%281%2Bi%29%5En-1%7D%7Bi%7D%20%5D)
where
FV is future value
now, we can plug values
![FV=75[\frac{(1+0.04)^{36}-1}{0.04} ]](https://tex.z-dn.net/?f=FV%3D75%5B%5Cfrac%7B%281%2B0.04%29%5E%7B36%7D-1%7D%7B0.04%7D%20%5D)
we get

The money after 3 years is $5819.8735
Answer:
1 stack of 60
2 stacks of 30
3 stacks of 20
4 stacks of 15
5 stacks of 12
6 stacks of 10
60 stacks of 1
30 stacks of 2
20 stacks of 3
15 stacks of 4
12 stacks of 5
Prime Factorisation

Step-by-step explanation:
To find the number of stacks you can make just divide the total by the size of the stacks. This also works in reverse.
To find the prime factorisation you just find the factors of the number by dividing it by the largest prime possible.
Answer:
A
Step-by-step explanation:
It is A, because it tells you the equation of
-5x + 8 ≥ -7
Because the key on the right tells you that shaded squares are negative and white ones are positive.
You can then subtract both sides by 8 to isolate the -5x and the equation becomes:
-5x ≥ -7 - 8
Which simplifies to
-5x ≥ -15
which you can now divide both sides by -5 to get
x ≥ 3
BUT WAIT
the general rule is that when you divide a variable (in this case x) by a negative number, you have to flip the inequality sign
so ≥
should become ≤
so the equation is x ≤ 3
