Answer:
A. y = 6x -1
Step-by-step explanation:
take two coordinates: (-1,-7) , (2,11)
slope:



....slope(m)
equation:
y - y1 = m(x - x1)
y - 11 = 6(x-2)
y = 6x -12 + 11
y = 6x -1
Answer: 280 calories in 3 ounces
Step-by-step explanation:
you can use a ratio to solve
840 calories per 9 ounces
unknown calories per 3 ounces


cross multiply
2520=9x
280=x
Answer:
The answer should be 81. Hope this helps!
Ducks have 1 head. Dogs have 1 head.
Ducks have 2 feet. Dogs have 4 feet.
If x = no. of ducks and g = no. of dogs
x + g = 25
2x + 4g = 80
Let's use substitution to solve.
x + g = 25 ⇒ x = 25 - g
replace x with 25 - g in the other equation and solve for g
2x + 4g = 80
2(25 - g) + 4g = 80
50 - 2g + 4g = 80
50 + 2g = 80
2g = 30
g = 15
Now use g = 15 in an earlier equation to find x.
x + g = 25
x + 15 = 25
x = 10
The length of A"B" is 20 units
<h3>How to determine the length of A'B'?</h3>
From the figure, we have:
A = (1, 4)
B = (4, 8)
The distance AB is:

So, we have:

Evaluate

This gives
AB = 5
The scale factor of dilation is 4.
So, we have:
A'B' = 5 * 4
Evaluate
A'B' = 20
Hence, the length of A"B" is 20 units
