Answer:
1. f(4) or f(n)= 28
2. f(-2) or f(n)= -2
(please consider marking brainliest <3 )
Step-by-step explanation:
n=4 n=-2
f(n)= 5(n)+8 f(n)= 5(n)+8
f(n)= 5(4)+8 f(n)= 5(-2)+8
(n)= 20+8 f(n)= -10+8
f(n)=28 f(n)=-2
<u><em>Answer: =1024. *The answer must be have positive sign.*</em></u>
Step-by-step explanation:
This question's it's about the order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right.
do exponents first.
16³/2=4098=2048¹/2
2048¹=2048
2048/2
divide left to right.
2048/2=1024
Hope this helps!
Thanks!
Have a great day!
Answer:
7. 5 
pizza
8. B
9. 11 
inches
10. -12
11. 
12. 4
Step-by-step explanation:
7. 3 
+ 2 
make them mixed fractions: 
+ 
get a common denominator by multiplying by 4: 
+
add the numerators: 
simplify the fraction by dividing 45 by 8: 5
8. 3 x 6 = 18
5 x 6 = 30
7 x 6 = 42
9 x 6 = 54
therefore, y = 6x
9. 5:7 is similar to 8:L
divide 8 by 5: 1 
multiply 7 by 1 : 11
L = 11 inches
10. 5 - 2x = 29
subtract 5 from each side: -2x = 24
divide each side by -2: x = -12
11. fruit = 15%
15% = 15/100
simplify by dividing by 5:
12. the y-intercept is where the line crosses the y-axis (the vertical one). the line crosses the y-axis at 4.
4 feet 6 inches
Step-by-step explanation:
P=2(l+w) [the addition of all sides of the rectangle]
P = 40'
L = 15’6”
So, 40' = 2 (15’6’ + w)
40' = 31’ + 2w
9' = 2w
4’6” = w
If it's easier you can break it change feet into inches and then change back to feet.
