Let f(x)=-2x-7 and g(x)=-4x+6 find (g o f )(-5)

Elza [17]

Easy

(g o f)(-5)=g(f(-5))

first evaluate f(-5), then input the result into g(x)

f(-5)=-2(-5)-7
f(-5)=10-7
f(-5)=3

g(3)=-4(3)+6
g(3)=-12+6
g(3)=-6

(g o f)(-5)=-6

HEB has dish soap that costs $2.80 for a 12oz bottle. Fiesta has the same dish soap that costs $2.00 for a 8 oz tube.

s2008m [1.1K]

Answer:

The unit rate at HEB is $0.23 per ounce. The unit rate at Fiesta is $0.25 per ounce. So HEB has the better buy for dish soap.

Step-by-step explanation:

To calculate unit rate, you divide the price by the oz.

So for HEB, you should do $2.80/12 oz. This will equal to $0.23 per ounce. For Fiesta, you should do $2.00/8 oz. This will equal to $0.25 per ounce.

To determine which one is the better buy, the lower priced one is better, meaning HEB is the better buy.

Help 0.06 is 10 times as much as

Ipatiy [6.2K]

Answer:

0.06 is 10 times as much as 0.006

Step-by-step explanation:

let the number be x

as per the condition 0.06 is 10 times as much as x.

Solve for x:

10 times as much as x represents as $10 \times x$

Then;

$0.06 = 10 \times x$ ......[1]

Division property of equality states that you divide the same number to both sides of an equation.

divide by 10 to both sides in equation [1];

$\frac{0.06}{10} = \frac{10x}{x}$

Simplify:

x = 0.006

Therefore, 0.06 is 10 times as much as 0.006
