Answer:
Below is a reference sheet.
Answer:
Step-by-step explanation:
She needs 12 pizzas
x + y = 12
She also can't spend more than 180 dollars.
8x + 11y < 180 She can get all 12 pizzas and have the bill come to 132 dollars
11 * 12 = 132
She could really be kind to her pocket book and get all cheese pizzas
8*12 = 96 which saves her 36 dollars.
So any number of either kind will do.
(0,12) = 132
(1,11) = 8*1 + 11*11 = 129
and so on down the line
Answer:
6. -2.5 + 3 = 0.5
Part B. -2.5 + x = y
4. a. Yes
b. No
c. No
d. Yes
1. C. -1/8 points
3. a. -3.7 + 8 = positive number 8 = a. 4/3 = d.
b. -8 - 1/1/3 = negative number -8 = b, c. -5 = b, d.
c. -8 + 8 = 0 -4.9 = b, d. -5.4 = b, d.
d. -4.52 + -4.9 = negative number 3.8 = a, d. 3.86 = a, d.
Step-by-step explanation:
Those are the correct answers.
Answer:
(1,-2)
Step-by-step explanation:
x= 1
y= 2
Answer:
7.6
Step-by-step explanation:
From the graph, we know the lengths of two legs.
a = 3
b = 7
Knowing this, we can use the Pythagorean Theorem to solve for c, the hypotenuse. (remember, a^2 + b^2 = c^2)
c = √a2 + √b2
= √(7)2 + √(3)2
= √49 + √9
= √58
= 7.6
