Answer:

If the two numbers are x and y, then:

x + y = 8

18 - 2x = 4y - 2.

When we subtract y from both sides in our first equation we get:

x = 8 - y, so:

18 - 2(8 - y) = 4y - 2

18 - 16 + 2y = 4y - 2

2 + 2y = 4y - 2

2y = 4

y = 2

Since x + y = 8, and y = 2, x = 6, and since 6 > 2, the larger number is 6.

What is the value of x in the product of powers below plz I need help
Alexeev081 [22]

Answer:

x = -7

Step-by-step explanation:

Recall this rule of exponents:

a^b*a^c = a^(b+c)

We have:

6^9*6^x = 6^2

Then 9 + x = 2.  Subtracting 9 from both sides, we get:  x = -7

If f(x)= 5x + 40, what is f(x) when x = -5?
kap26 [50]

Answer:

f(x) = 15

Step-by-step explanation:

"If f(x)= 5x + 40, what is f(x) when x = -5?"

Substitute x for -5:

f(x) = 5x + 40

f(x) = 5(-5) + 40

f(x) = -25 + 40

f(x) = 15
