Y = -3/4x - 2
Add 2 and subtract y
-3/4x - y = 2
No fractions or negative
Multiply all by 4
-3x - 4y = 8
Now multiply all by (-)
Solution: 3x + 4y = -8
Answer: y= 3x

Step-by-step explanation:
sine is opposite over hypotenuse,
so it's 40/50=4/5
Answer:
19 cars.
Step-by-step explanation:
Using a fraction is easy. Here's the ratio: 95/55
Reduce.
95/55 = ?/11
Divide 55 by 5 and you get 11. Do the same for 95. 95 divided by 5. Then you get 19. That's your answer.
Let us say that h is the height of the guardrail.
Therefore the inequality equation that we can generate from this scenario is:
| h – 106 | = ± 7
There are two ways to solve this, either the equation is
positive or negative.
When the equation is positive, therefore:
| h – 106 | = 7
h = 7 + 106 = 113 cm
When the equation is negative, therefore:
| h – 106 | = - 7
h = -7 + 106 = 99 cm
So the height must be 99 cm to 113 cm
