Multiply the 2nd equation by -3 to get -3x-12y = -48.
To do part A and B, note that functions are distributive, meaning (h+t)(x) = h(x)+t(x) and (h•t)(x) = h(x)•t(x).
Giving:
A: (h+t)(x) = 2x - 5 + 6x + 4 = 8x - 1
B: (h•t)(x) = (2x - 5)•(6x + 4) = 12x^2 - 22x - 20
C: h[t(x)] = 2[t(x)] - 5 = 2(6x + 4) - 5 = 12x + 3
Answer:
yes, the ordered pair is a solution for this equation
Step-by-step explanation:
y= -x-2
plug in 1 for x and -3 for y
-3= -1-2
-3= -3
Answer:
B. ⅔t
E. t-⅓t
Step-by-step explanation:
If Hakeem has a coupon for ⅓ off the regular price, t, of a tent.
The value of the coupon=⅓ of t
=⅓ X t =⅓t
Using this coupon, the value of the tent becomes: t-⅓t=(1-⅓)t= ⅔t
We are subtracting because there is a reduction in the price of the tent.
Therefore, options B and E represents the price of the tent if the coupon is used.
