Answer:
y = (-3/4)x - 5
Step-by-step explanation:
The general form of the slope-intercept equatin of a straight line is
y = mx + b, where m is the slope and b is the y-intercept.
Substituting -3/4 for m and -5 for b, we get:
y = (-3/4)x - 5
Answer:
x = ± sqrt(43)
Step-by-step explanation:
2x^2 - 28 = x^2 + 15
Subtract x^2 from each side
2x^2-x^2 - 28 = x^2-x^2 + 15
x^2 -28 = 15
Add 28 to each side
x^2 - 28 +28= 15+28
x^2 = 43
Take the square root of each side
sqrt(x^2) = ± sqrt(43)
x = ± sqrt(43)
Answer:
135
Step-by-step explanation:
A tutor charges 30.00$ for two hours of tutoring how much money would the tutor make in nine hours
So what you can do is:
3 breads * 4 meats * 7 toppings
Because there are four meats per each of the three breads and 7 toppings for each type of bread and meat combo.
so,
3 * 4 * 7
12 * 7
84
There are 84 sandwich combos.
