Answer:
- a) y = 3/4x - 8
- b) y = 1/7x + 7
- c) y = -5/7x - 3
- d) y = x + 8
Step-by-step explanation:
<u>Converting the equations from standard to slope-intercept form</u>
a)
- 3x - 4y = 32
- 4y = 3x - 32
- y = 3/4x - 8
b)
- x - 7y = -49
- 7y = x + 49
- y = 1/7x + 7
c)
- 5x + 7y = -21
- 7y = -5x - 21
- y = -5/7x - 3
d)
Answer:
he will have 40 kg
Step-by-step explanation:
10:5=2
20 x 2 = 40
For number 13 x=70 and y=115 hope this helped
Answer:
carnation $2.50; rose $3.00
Step-by-step explanation:
Let c = price of 1 carnation.
Let r = price of 1 rose.
3c + 5r = 22.5
3c + 2r = 13.50
Subtract the se3cond equation from the first equation.
3r = 9
r = 3
Now substitute r = 3 in the first equation and solve for c.
3c + 5r = 22.5
3c + 5(3) = 22.5
3c = 7.5
c = 2.5
Answer: carnation $2.50; rose $3.00
600,000,000+ 70,000,000+ 200,000+ 600+ 40
