I mean, I would assume it’d just be n/2? Because you have n, which you don’t know the number for, and then you divide by 2, leaving n divided by 2 which is n/2

Answer:

see below

Step-by-step explanation:

(x) = 7 - 2x

Let t(x) =0

0 = 7-2x

Subtract 7 from each side

-7 = -2x

Divide by -2

-7/-2 =-2x/-2

7/2 =x

h(x) = 4x + 2

Replace x with x+3

h(x+3) = 4(x+3) + 2

Distribute

= 4x+12 +2

=4x+14

The exponential function y= a(b)^x passes through the points (3,25) and (8,10). Which of the following is closest to the value o

Yuki888 [10]

If the exponential function $y=ab^x$ passes through the points (3,25) and (8,10), the value of b is 0.833

The given exponential equation is:

$y=ab^x$

The function passes through the points (3, 25) and (8, 10)

Substitute x = 3 and y = 25 into the function $y=ab^x$

$25=ab^3$ ............................(1)

Substitute x = 8 and y = 10 into the function $y=ab^x$

$10=ab^8$ .............................(2)

Divide equation (2) by equation (1)

$\frac{10}{25}=\frac{ab^8}{ab^3} \\\\0.4=b^5\\\\b=0.4^\frac{1}{5} \\\\b=0.4^{0.2}\\\\b=0.833$

Therefore, if the exponential function $y=ab^x$ passes through the points (3,25) and (8,10), the value of b is 0.833

Answer this: 15 cookies to 40 brownies as a ratio in simplest form.

Nutka1998 [239]

Solutions

⇒15 Cookie to 40 brownies can be written as 15:40

⇒15:40 is the ratio we have to simplify

The GCF of 15 and 40 is 5 so we divide them by 5

15 ÷ 5 = 3
40 ÷ 5 = 8

3:8 is in simplest form

A building has a concrete foundation that’s 24” wide and 36” deep at all points. How many cubic yards of concrete are necessary

Iteru [2.4K]

Answer:

5/9 cubic yards

Step-by-step explanation:

Just so L*W*H=24(36)(30)= 25920 cubic inches=25920 (1 in*1 in* 1 in)

36 in=1 yd

1 in =1/36 yd

do divide 25920 by (36*36*36)

The answer in cubic yards is 5/9 cubic yards
