Answer:
<em>y=-6</em>
Step-by-step explanation:
<u>Proportions</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Substituting x=-3 y=9:
9 = k(-3)

Now the relationship is:
y = -3x
For x=2
y = -3(2) = -6
Answer:
2x +3y = -10
Step-by-step explanation:
The given line equation is in standard form, so the one we write will match that form. A parallel line will have the same x- and y-coefficients, but a different constant on the right.
Put the point values in the left-side expression to find the required right-side constant: (x, y) = (1, -4)
2(1) +3(-4) = constant = 2-12 = -10
Your line is ...
2x +3y = -10
Answer:
14 cups
Step-by-step explanation:
20-2.50= 17.50
<u>17.50 </u>= <u>1.20x</u>
1.20 1.20
x=14.6 or 14 cups
AC is the hypotenuse of triangle ABC.
Because the length is 6√2 and angle A is 45 degrees, we know the length of both sides is 6.
This means AB is 6, which it the hypotenuse of triangle BCD.
Using cos(angle) = adjacent leg / hypotenuse we can find x:
cos(60) = X / 6
x = 6 * cos(60)
x = 3
Answer:
16
Step-by-step explanation:
he missed 25%
if 4 = 25% then 16 questions total
4*4=16 and 25% * 4 = 100%
