Paul has 70 Total sport cards.
3 (Baseball) + 3 (Football) + 4 (Baseball) = 10 (Total cards per pile) × 7 (Total Piles) = 70 (Total Cards
3+3+4=10×7=70
(All shown work is this ^)
If I'm right please help me out by following me. Thank you for your wonderful question~!
I think x= -7 because 4x7=28
Hey how are you doing today?
Answer:
Step-by-step explanation:
A to C
y = b + mx
b = y-intercept
m = slope of line
Looking at the line, the line crosses the y-axis at the coordinates (0,0). This means that the y-intercept is 0.
The slope formula is m=(y2-y1)/(x2-x1). Using the points on the line (-1, -3) and (1,3) we find that the slope is, 3.
Looking back we can see that our variables now have value so we can plug them into our formula.
y = b + mx
b = 0
m = 3
Substitute
y = 0 + 3x
Answer:
B and C
(I'm not sure if b and e are supposed to be the same though) if they are then, b, c, and e
