It’s actually all except bottom left
This equation is already in slope intercept form.
Slope intercept form is y = mx + b, which is the form it is in now. However, if you would like it changed to standard form, you would multiply by the lowest common denominator and then rearrange as follows.
y = -1/7x + 22/7 -----> Multiply both sides by 7
7y = -x + 22 ------> Add x to both sides
x + 7y = 22
Answer:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
10% = 10/100 = 10 ÷ 100 = 0.1.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 10% of its value.
Percentage increase = 10% × 2,880
New value =
2,880 + Percentage increase =
2,880 + (10% × 2,880) =
2,880 + 10% × 2,880 =
(1 + 10%) × 2,880 =
(100% + 10%) × 2,880 =
110% × 2,880 =
110 ÷ 100 × 2,880 =
110 × 2,880 ÷ 100 =
316,800 ÷ 100 =
3,168
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 2,880 =
3,168 - 2,880 =
288

Answer:
the duration of this event is 4 hours
Step-by-step explanation:
This function is a quadratic one
let Δ be the dicriminant :
- a = -16
- b = 48
- c= 64
- Δ = 48²-4*(-16)*64 = 6400
so there are two values that satisfy -16t²+48t+64 = 0 x and y
- x= (-48+80)/-16*2 = -1
- y= (-48-80)/-16*2= 4
x<0 so w won't take it since time is a positive value here
so t = y = 4h
