Answer:
5 days and 5 hours
Step-by-step explanation:
24*5=120
125-120=5
Answer:
Step-by-step explanation:
I'm assuming that your "70=50x what is xx" actually means "find x if 70-50x = 0" If that's not what you meant, please retype your question.
Dividing both sides by -50 results in -70/50 + x = 0, and adding 70/50 to both sides results in x = 70/50, or 7/5.
Only if my assumptions are correct: x = 7/5.
Answer:
x=

Answer:
slope = 35; y-intercept = -45
Step-by-step explanation:
Function f(x) is written in the slope-intercept form, y = mx + b.
f(x) = -7x + 9
You compare it with
f(x) = mx + b, and you see that m, the slope, is -7, and b, the y-intercept is 9.
Now we deal with function h(x).
h(x) = -5(-7x + 9)
This is not written in the y = mx + b form, but we can put it in that form by distributing the -5.
h(x) = 35x - 45
Now, h(x) is written in the y = mx + b form. We see clearly that m = 35, so the slope of function h is 35. We also see that b, the y-intercept is -45.
Answer: slope = 35; y-intercept = -45
Is it 2 different questions or just one?
