Answer: x = -1 and y = -2
Step-by-step explanation:
You are given two expressions that have a relationship. There are two ways to solve this problem, but I will be going over the easy way. I'm assuming you know how to solve for one variable such as x? Well we can put the y varaible from the first equation in terms of x, from the second equation. Ill show you what I mean:
6x + 5(7x + 5) = -16
I replaced y in the first one in terms of x, so that we can solve just for x.
6x + 35x + 25 = -16
41x +25 = -16
41x = -41
x = -1
Now simply find y by plugging the now known x value into either equation
y = 7(-1) + 5
y = -2
Y=kx so 3 would be the constant
Answer:
ounces
Step-by-step explanation:
Since Ethan needs 
ounces of blue paint to make 1 batch of green paint, we can multiply the amount of blue paint needed by 5 to see how much blue paint he'll need for 5 batches of green paint.
This means he will need ounces of blue paint to make 5 batches of green paint.
Answer:
50√3/3
Step-by-step explanation:
30-60-90 triangle
50:x = 2sqrt3 : 2
50*2 =100
100/2sqrt3 = 3
50√
3

Answer:
Here we need to solve:
The sum of the fractions is equal to the quotient between the fractions.
Notice that the two values:
y = 3
y = -3
make the denominator equal to zero, so those values are restricted.
We can simplify the right side to get:
Now we can multiply both sides by (y - 3)
Now we can multiply both sides by (y + 3)
First, let's see the determinant of that quadratic equation:
We can see that it is negative, thus, there are no real solutions of the equation.
Thus, there is no value of y such that the origina equation is true,
