Each variable used is the first letter of each of their names.
t+b+c=87
c=2t
b=t+7
Substitute for b and c
t+ (t+7)+2t= 87
4t+7=87
4t=80
t=20
Plug in the known t value.
c=2(20)
c=40
b=20+7
b=27
Final answer: Tammy=$20, Boris= $27, Carlos=$40
Step-by-step explanation:
Since y = (x + 3)(x + 3), the root is x = -3.
Only Graph A touches the x-axis once.
Answer:
65%=$260
Step-by-step explanation:
40%+25%=65%
65% of 400
65/100*400
=$260
Answer:
Third choice: y + 7 = -2(x - 3)
Step-by-step explanation:
One of the two given points is (3, -7): (h, k), which would be the given point in the point-slope form of the equation of a straight line:
y - k = m(x - h)
If we replace h with 3 and k with -7, we get
y + 7 = m(x - 3).
Next, let's calculate the slope, m: as we go from (2, -5) to (3, -7), x increases by 1 and y decreases by 2. Hence, the slope is m = rise / run = -2/1, or -2.
Thus, the third answer choice is the correct one: y + 7 = -2(x - 3).
