Answer:
The first number is −13 and the second number is −6
Step-by-step explanation:
The first number is −13 and the second number is −6
<u>Explanation:</u>
<u>Let's let the first number be n and the second number be called m.</u>
<u>Then, from the first sentence we can write:</u>
n = m − 7
<u>and from the second sentence we can write:</u>
2n = 6m + 10
<u>Substitute m − 7 for n in the second equation and solve for m:</u>
2(m − 7) = 6m + 10
2m − 14 = 6m + 10
2m − 14 − 2m − 10 = 6m + 10 − 2m − 10
−14 −10 = 6m −2m
−24 = 4m
-24/4 = 4m/4
m= −6
<u>Now substitute −6 for m in the first equation and calculate n:</u>
n = −6 −7
n = -13
The first step in isolating z would be multiplying both sides by 4 to cancel out the fraction
after that you have
4x = 2y - z
subtract 2y
4x - 2y = - z
divide both sides by -1 to completely isolate z
-4x + 2y = z should be your answer

Step-by-step explanation:
f(1) is simply the value of f(x) when x = 1. Therefore, looking at the graph, when x = 1, f(x) = 1.
