Answer:
s = 4w+56
Step-by-step explanation:
$4 per week so 4w
56 Francisco already had so its at the end
Answer:
<ADB = 75 degrees
Step-by-step explanation:
We know, a straight line has an angle of 180 degrees.
A = (180-143) = 37 degrees.
A + C = (37 + 38) = 75 degrees.
The angles of a triangle will always add up to 180 degrees.
<ADC = (180-75) = 105 degrees.
So,
<ADB = (180-105) = 75 degrees.
Hope, this will help. Please mark me brainliest.
Thank you.
Answer:
B) y = 10x
Step-by-step explanation:
It should not be too hard for you to determine that every number on the bottom row is the same as the number on the top row with a zero appended.
Appending a zero to a number is the same as multiplying it by 10. For example, ...
... 90 = 10·9
... y = 10x
_____
In case that observation doesn't work out for you, you can always solve the given equation for k, then choose values from the table to fill in.
... y = kx
... k = y/x . . . . . divide by the coefficient of k, which is x
Fill in values from the table
... k = 20/2 = 10 . . . . . . from the second column
Now put this value where k is in the equation. After you do that, you know ...
... y = 10x
First, subtract the initial cost from the total cost.
$75.49 - $29.99 = $45.50
Then, divide this by the rate charged for miles.
$45.50/$0.26 = 175mi
Therefore, Al drove 175 miles.
Vertex: (4,-11)
Focus: (4, -43/4)
Axis of Symmetry: x=4
Directrix: y=-45/4
I hope this is what you're asking for, and if not then just tell me what answer choices you have and I'll see what I can do from there. Thanks
