Answer:
D.) Add 16 to both sides of the equation
Step-by-step explanation:
By adding 16 to both sides, you are eliminating the -16 on the left. You must do it to both sides in order to balance the equation.
Answer:
- 4 < x ≤ 7
Step-by-step explanation:
Given
- 10 ≤ - 5x + 25 < 45 ( subtract 25 from all 3 intervals )
- 35 ≤ - 5x < 20
Divide all 3 intervals by - 5, reversing the inequality signs as a consequence.
7 ≥ x > - 4
Hence - 4 < x ≤ 7
Answer:
y=35z+20
Step-by-step explanation:
Y is the total cost, so it goes on the outside. 35z represents the months of service because you multiply 35 by however many months there are (for example, if you had 3 months, you'd have $35 3 times). Finally, the $20 is tacked onto the end because that's the initial payment to open an account
50L x 3 = 150. 4L x 15 = 60. 0.2L x 12 = 2.4. 150 + 60 + 2.4 = 212.4L.
These intercepts<span> are plotted in Figure 3.1 and the line </span>3x<span> + </span>2y<span> = </span>12<span> is drawn through them. Figure 3.2: Adding the graph of </span>y<span> = </span>x<span> + 1. The second equation </span>y<span> = </span>x+ 1 has slope-intercept<span> form </span>y<span> = mx + b. Hence, the slope is m = 1 and the </span>y-intercept<span> is (0, 1).</span>
