Answer:

B. x =1 , y = -5

Step-by-step explanation:

So, what we can do is to simply plug in all of the equations and see which one fits. Equation: x - y = 6

A. x =1 , y = -6

1 -(-6) = 6

1 + 6 = 7

A would be incorrect.

B. x = 1, y = -5

1 - (-5) = 6

1 + 5 = 6

Therefore, B would be correct.

H+20=35-4h please help

andrew-mc [135]

H+20=35-4H
first, combine your like terms, which are the Hs
add the 4H to both sides, and you will get
5H+20=35
now subtract 20 from both sides, that will cancel out the 20 on the left and leave you with
5H=15
finally, divide both sides by 5 and you will get H=3.

Question 1 of 40<br> If f(x) = 4x² - 6 and g(x) = x² - 4x-8, find (f- g)(x).

Aleksandr-060686 [28]

Answer:

$\huge\boxed{\sf (f-g)(x) = 3x\² + 4x - 14}$

Step-by-step explanation:

<h3><u>Given functions:</u></h3>

f(x) = 4x² - 6
g(x) = x² - 4x - 8

<h3><u>Solution:</u></h3>

Subtract both functions

(f-g)(x) = 4x² - 6 - (x² - 4x - 8)

(f-g)(x) = 4x² - 6 - x² + 4x - 8

Combine like terms

(f-g)(x) = 4x² - x² + 4x - 6 - 8

(f-g)(x) = 3x² + 4x - 14

Lend me a hand please

Nookie1986 [14]

Answer:

A) y>=-1

Step-by-step explanation:

The line itself is y=-1, but it is also filled in. Therefore, we are down to either A or C as the right answer

Since (0,0) is a solution to the inequality as indicated by the shade, we know that since y=0 in the origin, 0 is greater than -1, so therefore A is the correct answer.

11. A physical therapist is using a wide elastic band to help a

Vinvika [58]

Answer:

(C) 5 decimeters

Step-by-step explanation:

A therapist is using an elastic band to strengthen a patient's knee after surgery.

The patient's knee can tolerate a maximum of 20 kg i.e. 20000 gm weight of force.

If the elastic band provides 40 gm of weight force for every millimeter of its extension.

then this can be extended up to $\frac{20000}{40} =500$ millimeters, which is equal to 5 decimeters.

Therefore, option c is correct. (Answer)
