Answer:
The store sold 21 T-shirts and 18 pairs of shorts.
Step-by-step explanation:
x = the number of T-shirts sold
y = the number of pairs of shorts sold
x + y = 53
12x + 9y = 570
x = 21 T-shirts
y = 18 shorts
The differnce quotient is basically taking the derivitive (result will be f'(x)=5, but anyway)
here is the disffernce quotient
![lim_{h\rightarrow0}\frac{f(x+h)-f(x)}{h}](https://tex.z-dn.net/?f=lim_%7Bh%5Crightarrow0%7D%5Cfrac%7Bf%28x%2Bh%29-f%28x%29%7D%7Bh%7D)
so
for your equation
![lim_{h\rightarrow0}\frac{(5(x+h)+4)-(5x+4)}{h}](https://tex.z-dn.net/?f=lim_%7Bh%5Crightarrow0%7D%5Cfrac%7B%285%28x%2Bh%29%2B4%29-%285x%2B4%29%7D%7Bh%7D)
![lim_{h\rightarrow0}\frac{5x+5h+4-5x-4}{h}](https://tex.z-dn.net/?f=lim_%7Bh%5Crightarrow0%7D%5Cfrac%7B5x%2B5h%2B4-5x-4%7D%7Bh%7D)
![lim_{h\rightarrow0}\frac{5h}{h}](https://tex.z-dn.net/?f=lim_%7Bh%5Crightarrow0%7D%5Cfrac%7B5h%7D%7Bh%7D)
h's cancel and you are left with 5
the differnce quotient is 5
The answer would be 140° or D because supplementary means the angles add up to 180°. Therefore, 180°-40°=140°
Answer:
Yes
Step-by-step explanation:
Only one section should be coloured in because it's 1/8 of the spinner. Meaning, there is one chance of landing on any colour.
