2x - 8y = 6
-2x + 2y = 7
Add the two equations together by combining like terms:
2x + -2x = 0
-8y + 2y = -6y
and 6 + 7 = 13
So when you combine the terms you end up having:
-6y = 13
Now solve for y by dividing each side by -6:
y = 13/-6
Rewrite by moving the negative sign in front of the fraction to get
y = -13/6
The answer is C.
Solve for y in the two equations below using substitution.
2x - 8y = 6 -2x + 2y = 7____________________Solution :-Given Information :-Equation 1 ➢ 2x - 8y = 6 Equation 2 ➢ -2x + 2y = 7 To Find :-Solve for y in the two equations.Calculation :-Equation 1 ➢ 2x - 8y = 6
Equation 2 ➢ -2x + 2y = 7
Adding both equations together, by combining similar terms, We get,
2x + -2x = 0-8y + 2y = -6y6 + 7 = 13When we combine the terms, We get,
⇒ -6y = 13
Now, solving for y, by divide Right Hand Side & Left Hand Side by -6, We get,
⇒ y = [tex] \sf \frac{13}{-6} [/tex]
⇒ y = [tex] \sf \frac{-13}{6} [/tex]
∴ The value of y is [tex] \bf \frac{-13}{6} [/tex]
____________________Final Answer :-The value of y is [tex] \bf \frac{-13}{6} [/tex]
Hence, Option C. [tex] \bf \frac{-13}{6} [/tex] is correct answer.

Which statement about 214° is correct?
O A. tan 214° < 0
O B. sin 214° < 0
O C. cos 214° > 0
Answers
Answer:
B.
Step-by-step explanation:
214 degree terminates in the 3rd quadrant.
Sine and cosines are both negative there.
This means that sin(214)<0 and cos(214)<0.
If sine and cosine are both negative and since tangent is the quotient of them, then tangent is positive, or tan(214)>0.

Answers
Answer:
3 15/18
Step-by-step explanation:
well, 4 5/18 can't take away 8/18 with the fraction itself. so, you take 5 from 8 and get -3. then, take one whole number away and subtract the 18 from 3 (this was the negative 3) and you have the answer. so to conclude it 5 cant take away 8 so its like carrying. you take one whole number that is 18/18 and you subtract the 18 from 3.

what is the area of the unshaded path
Answers
Answer:
114 feet
Step-by-step explanation:
the black and white will both have the same area. and given that each path is 1 ft wide and initially 12 ft long we can slowly determine the area.
x times 1 will still equal x
12(1) still equals 12 so we can just write it as 12.
12+12+11+11+10+10+9+9+8+8+7+7= 114
where I came up with this? there are a total of 12 sides if you follow the black path. and by every 2 sides the path gets shorter by 1 foot.
the white side also has 12 sides if you look. therefore both the black and the white part of the shape will have an area of 114.

60=70-h I can't seem to find my answer and it a bit hard
Answers
Answer:
10
Step-by-step explanation:
We need to solve the equation . The equation is z
→ 60 = 70 - h
Subtracting 70 both sides .→ 60 - 70 = 70 - h - 70
→ -10 = -h
Dividing both sides by -1 .→ -h/-1 = -10/-1
→ h = 10
• Hence the value of h is 10 .Use the Figure to find the measure of the angle. Explain your Reasoning.

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 15 hours. Together they charged a total of $2475 . What was the rate charged per hour by each mechanic if the sum of the two rates was $200 per hour?
Answers
Answer:
1st: 105/h
2nd: 95/h
Step-by-step explanation:
10A+15B=2475 (1)
A+B=200 |*10 => 10A+10B=2000 (2)
From (1) - (2), we have 5B=475, so B=95
then A+95=200 so A is 105
