Answer:
y=3x+25
Step-by-step explanation:
So to find the slope-intercept we need to find the slope and the y intercept. we already know the slope so to find the y intercept you subtract 2 from the x coordinate and 6 from the y, because the slope is 3. So the answer is y=3x+23
Answer:
y>60
2*x+2*x<260
it's the only one that works
Step-by-step explanation:
Mx+b=y
subtract b from both sides
mx=y-b
divide m in both sides
x=(y-b)/m
Answer:
d. only the first equation is an identity
Step-by-step explanation:
ANSWER:
50% increase
The percent of change of 30 increased to 45 is a 50% increase.
STEP-BY-STEP EXPLANATION:
% of change = [ ( New amount - original amount ) / original amount ] × 100%
Let % of change = x
x = [ ( 45 - 30 ) / 30 ] × 100%
x = ( 15 / 30 ) × 100%
x = ( 1 / 2 ) × 100%
x = 0.5 × 100%
x = 50%
