Answer:

Su=10

Explaination:

So from s to u on the nunebr line is worth 2x-12. So what is s to u worth? Well. S to t on the number line = x-7. T to u =6. And 2 x is worth 12 more than s to u, using th e expression. X has to be at least 8 because otherwise the x-7 wouldn't work, and u might get s to u = 0 or a negative number.

Say x was 13, then 13 - 7 =6. So S to t =6. And r to u =6. So s to u =12. (6+6). Then check if the expression fits this answer of 12. 2x - 12. 2x = 26. 26-12=14, which doesn't match.

Let's try 14. 14-7=7. Then s to u = 7+6=13. The expression: 2x= 28. 28-12=16. 13 and 16 dont match. So we have got further away from what we need. Why don't we try going in the opposite direction. Rather than testing 13 and +1, let's now - 1 and try 12.

If x=12, then s to t =12-7=5. And s to u =6+5=11. The expression: 2x=24.-12=12. We are very close now with 11 and 12.

Lets test x=11!

S to t = 11-7=4. 4+6=10. So s to u =10.

2x=22. 22-12=10. So the expression works and the number line measurements.

The answer is su=10 and x=11.

A train left for Houston, and 7 hours later, a car traveling 62 mph tried catching up to the train. After 4 hours, the car caugh
lana [24]

Answer: 22.55 mph

Step-by-step explanation:

Let the speed of the train be n

4 × 62 = 248 which is the distance travelled by the car in 4 hours and the train travelled in 11 hours

11 × n = 248

11n = 248

n = 248/11

n = 22.55mph

I need help with this promblem it’s ALGEBRA 2!
AlekseyPX

Answer:

(f\circ h)(2)=2

Step-by-step explanation:

<u>Composite Function </u>

Given f(x) and h(x) real functions, the composite function named (f\circ h)(x) is defined as:

(f\circ h)(x)=f(h(x))

It can be found by substituting h into f.

We are given the functions:

f(x)=2x^2-9x+2

h(x)=x^2-4

It's required to find (f\circ h)(2)

As defined above:

(f\circ h)(x)=f(h(x))

Thus:

(f\circ h)(2)=f(h(2))

Find h(2):

h(2)=2^2-4=0

h(2)=0

Now:

(f\circ h)(2)=2(0)^2-9(0)+2

(f\circ h)(2)=2
