Step-by-step explanation:
y = -x² + 5
x = -2
y=-(-2)²+5
y= -4+5
y=1
1) pages per minute is the rate. the rate is the slope pages/minutes = .4
y=.4x or y=2/5(x)
2)birdhouses per day is the slope. = .6
y=.6x or y=3/5(x)
3) miles per hour is the slope. 500/8=62.5
y=62.5x
4) square feet per minute is the slope. 40/9 =4.444444444
y=4.4444444444x or y=40/9(x)
5)miles per minutes is the rate. 5/41 is the slope.
y=5/41(x)
6) the rate is square feet per minute. 450/30=15
y=15x
Answer:
6x - 3
Step-by-step explanation:
Step 1: Write out expression
2 - 3x - 5 + 9x
Step 2: Combine like terms (x)
2 - 5 + 6x
Step 3: Combine like terms (constants)
-3 + 6x
Step 4: Rewrite
6x - 3
Answer: formula - (x/4)+x
Step-by-step explanation:
Since there are no numbers, here is just the formula and what it means :)
(x/4)+x
(btw x is whatever your number is)
so what you need to do first is to divide your number by 4 because 25% is 1/4 of 100%
and then add that number that you just got to your number.
Its a little confusing to say out in words, so here is an example using 24
24/4=6
24+6=30
and heres another example using 50
50/4=12.5
50+12.5=62.5
I hope this helped! <3
