Solve the system of equations by substitution. y = 2x y = x +1
Step-by-step explanation:
y = 2x
y = x + 1
y-1 = x
y = 2x
y = 2 (y - 1)
y = 2y - 1
y = -1

Help! i don't understand :/
Answer:
Option C
Step-by-step explanation:
Given inequality is,
-3(2x - 4) ≤ 7(3 - x)
Solve the given inequality further,
-6x + 12 ≤ 21 - 7x
(-6x + 12) + 7x ≤ (21 - 7x) + 7x
x + 12 ≤ 21
(x + 12) - 12 ≤ 21 - 12
x ≤ 9 Or {x real | x ≤ 9}
Therefore, Option C will be the correct option.

The price of a computer component is decreasing at a rate of 10% per year. State whether this decrease is linear or exponential. If the component costs $ 110 today, what will it cost in three years?
Answer:
The cost in 3 years is $80.19.
Step-by-step explanation:
The cost of computer component is $110 today.
The cost is decreasing at a rate of 10% per year.
When it decreases by 10% per year then it is exponential.
Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.
So, we could use the exponential formula y=[tex]ab^{x}[/tex]
Where 'a' is initial cost and b is decay factor.
Our equation would by plug in 'a' as 110 and 'b' as 0.90.
We get
[tex]y= 110(0.9)^{x}[/tex]
Now, to find the cost in 3 years, use x as 3.
[tex]y=110(0.9)^{3}[/tex]
Which is simplified to
y=$80.19

PLEASE HELP! MATH!
t = 12r/(r+120)
t(r+120) = 120r
tr+120t = 120r
tr-120r = -120t
r(t-120) = -120t
r = -120t/(t-120)
r = 120t/(120-t)

Answer:
41
Step-by-step explanation:
y = (4*5) + 21
y = 20 + 21
y = 41
Answer: 41
Step-by-step explanation:
Basically multiply the input value by 4, since the input is x. You will have 4(5) which is 20, then add 21 to it and you have 41.
Hey so can somebody help me? Please dont guest on this, im on the test and i dont want to fail, so please actually try thanks (you will get brainliest if you explain where the arrow goes and the answer of the problem) ( but the main point is to explain where the arrow goes)
Answer:
The answer would be -2 1/6
Step-by-step explanation:
The arrow goes to the left side because it is negative. -1/3 would be equal to -2/6. -5/6 + -1/6 + -1/6 = -1 1/6. Add the 1 and you get -2 1/6!

.prove that cos (90-A).sinA + sin(90 - A).cosA = 1
Answer:
See Explanation
Step-by-step explanation:
[tex]cos (90-A).sinA + sin(90 - A).cosA = 1 \\ \\ LHS = cos (90-A).sinA + sin(90 - A).cosA \\ \\ = sinA.sinA + cosA.cosA\\ \\ = sin ^{2} A + cos^{2} A \\ \\ = 1 \\ \\=RHS\\\\ reason \\ cos (90- \theta) = sin \theta \\ sin (90- \theta) = cos \theta \\ sin ^{2} \theta + cos^{2} \theta = 1 \\ \\ thus \: proved \\ [/tex]
Which equations have the same value of x as Two-thirds (6 x + 12) = negative 24? Select two options.
4 x + 8 = negative 24
9 x + 18 = negative 24
4 x = negative 16
18 x + 36 over 2 = negative 24
4 x = negative 32
Answer:
4x+8=-24 and
4x=-32

Answer:
The coordinates of point P are (1, -1)
Step-by-step explanation:
If the point (x, y) reflected about the x-axis, then its image is (x, -y)To find the image of a point reflected about the x-axis change the sign of its y-coordinateThe rule is R x-axis → (x, -y)If the point (x, y) reflected about the y-axis, then its image is (-x, y)To find the image of a point reflected about the y-axis change the sign of its x-coordinateThe rule is R y-axis → (-x, y)→ Assume that the coordinates of point P are (x, y)
∵ The coordinates of point P are (x, y)
∵ The rule of the reflection is R y-axis (P)
∴ Its image = (-x, y)
∵ The image = (-1, -1)
→ Equate the two images
∴ (-x, y) = (-1, -1)
∴ -x = -1
→ Divide both sides by -1
∴ x = 1
∵ y = -1
∴ The coordinates of point P are (1, -1)

A company's profits for a week are as follows:
Monday: +$32.65, Tuesday: -$75.32,
Wednesday: -$125.75, Thursday: +$100.89,
and Friday: +$65.30. Does the company show
a gain or loss at the end of the week?
Answer:
Loss
Step-by-step explanation:
If you add all the numbers up you get -2.23 which would be a loss
Answer:
The company shows loss
Step-by-step explanation:
32.65 - 75.32= -42.67 so they're already at a loss
you would add -125.75 and -42.67 and woud get -168.42
Then you would add 100.89 and 65.30 and you would get 166.19
166.19+(-168.42)=-2.23

What is the slope of the line?
Answer:
The slope is : -2/2
Step-by-step explanation:
To find the slope, start on the y-axis. -2 passes through the line on the y-axis so start there. Go up 2 unites, which will bring you to the origin. Now you need to reach -2 on the x-axis. Go left two units, which gives you 2/2. It's rise over run. It's -2 because you went left two units not right. When you go left, or down it'll be negative.
2 = rise
/
-2 = run
(x₁,y₁) = (-2,0)
(x₂,y₂) = (0,-2)
m = (y₂ - y₁)/(x₂ - x₁)
m = (-2 - 0)/(0 - (-2))
m = -2/2
m = -1
