The unit rate for one serving would be 132 calories, and the total calories in 3 cups would be 396 calories.
Step-by-step explanation:
You solve you the unit rate by multiplying 99 calories by 4 then dividing the amount by 3 and get 132 calories. Finally, you multiple by 3 and get 396 caloriesm
Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4
Answer:
Step-by-step explanation:
<u>Given function</u>
From the table we get the function g(x), use pairs (1, 10) and (3, 14)
<u>The slope:</u>
- m = (14 - 10)/(3 - 1) = 4/2 = 2
<u>The y-intercept:</u>
- 10 = 2(1) + b
- b = 10 - 2
- b = 8
<u>The function g(x) is found as:</u>
<u>The y- intercept of f (x) is subtracted from the y-intercept of g (x):</u>
Answer:
the last one (bottom right)
Step-by-step explanation:
4×pi is the same as twice around the whole circle to the beginning. it is the same as 0°, and cos(0) = 1, and then -2×cos(0) = -2
so, we only need to look, where the function reaches -2.
it should be at x = 0, x = 0.5 and x = 1.
