Answer:
If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
Step-by-step explanation:
Answer:
y = (1/4)x - 1
Step-by-step explanation:
Start with the general slope-intercept form: y = mx + b. Subst. -1 for b and (1/4) for m. Then,
y = (1/4)x - 1
Answer: -1/2
Step-by-step explanation: to find slope, use the equation (y2-y1) / (x2-x1)
(-6 - -3) / (7 - 1)
-3 / 6
= -1/2
Answer:
answer is 90 for first term
Step-by-step explanation:
Let the terms be
First term x
We will use the formula s∞=x/1−r to find the sum of an infinite geometric series, where −1<r<1.
We know the sum and the common ratio, so we'll be solving for x where r =4/5
s∞=x/1−r
450=x/1−4/5
450=x/1/5
450=5x
x=90
this is the first term x1 = 90
we know that common ratio is 4/5, so multiplying the first term by factor 4/5 to get the second term
90 x 4/5= 72 second term
