Answer:

When the two values are different

Step-by-step explanation:

Like in an inequality equation.

For example:

$4+5x\geq 30$

The answer would be anything greate than or equal to 30, but you would need to find x. The number line would be very useful

Hope this helps

F(x)=3x−4g(x)=−x2+2x−5h(x)=2x2+1j(x)=6x2−8xk(x)=3x2−x+7 Calculate (fh)(x).

Answer:

( f h ) (x) = 6 x² - 1

Step-by-step explanation:

Step(i):-

Given f(x) = 3 x - 4

g (x) = −x²+2 x−5

h (x) = 2 x² + 1

j (x) = 6 x + 2 - 8 x

K (x) = 3 x² - x + 7

Step(ii):-

( f h ) (x) = f ( h (x)) = f ( 2 x² + 1 )

= 3 (2 x² + 1 ) - 4

= 3 ((2 x² ) + 3 - 4

= 6 x² - 1

Final answer:-

∴ ( f h ) (x) = 6 x² - 1

Derek ran less than 6 miles. If the race is 6 miles, and he only ran 3/8, he ran less than a half of the race. If he didn't finish the race of 6 miles, he couldn't possibly have run 6 miles.

sweet-ann [11.9K]

Answer:

The store sold 43 pro NSL soccer balls.

The store sold 27 limited Edition soccer balls.

Step-by-step explanation:

Let x represent number of limited Edition soccer balls and y represent the number of pro NSL soccer balls.

We have been given that a sports store sells a total of 70 soccer balls in one month. We can represent this information in an equation as:

$x+y=70...(1)$

Cost of x limited Edition soccer balls: $65x$

Cost of y pro NSL soccer balls: $15x$

We are also told that store collected a total of $2,400. We can represent this information in an equation as:

$65x+15y=2400...(2)$

From equation (1), we will get:

$x=70-y$

Substituting this value in equation (2), we will get:

$65(70-y)+15y=2400$

$4550-65y+15y=2400$

$4550-50y=2400$

$4550-4550-50y=2400-4550$

$-50y=-2150$

$\frac{-50y}{-50}=\frac{-2150}{-50}$

$y=43$

Therefore, the store sold 43 pro NSL soccer balls.

Now, we will substitute $y=43$ in equation (1) to solve for x:

$x+43=70$

$x+43-43=70-43$

[tex]x=27/tex]

Therefore, the store sold 27 limited Edition soccer balls.
