Answer:

-6 is the answer.

Step-by-step explanation:

4x - 5 = x - 23

or, 4x - x = -23 + 5

or, 3x = -18

or, x = -18/3

therefore, x = -6

Answer:

the answer is (3)

Step-by-step explanation:

4x - 5 = x - 23

<h3>i) bring -5 to the right-hand side and change its sign</h3>

4x = x - 23 + 5

<h3>ii) calculate the value</h3>

4x = x - 18

<h3>iii) bring x to the left-hand side and change its sign</h3>

4x - x = -18

<h3>iv) calculate the value</h3>

3x = -18

<h3>v) divide both sides of the equation by 3</h3>

\frac{3x}{3}  =  \frac{ - 18}{3}

x =  - 6

daser333 [38]

Answer:

d. Twenty-five cars are randomly selected with the new transmission and 25 with the old transmission.

Step-by-step explanation:

A hypothesis test on the difference between the means must satisfy the following conditions

1) the samples must be randomly selected

2) each sample must have a known standard deviation

3) the samples must be independent

4) the samples must be from normal distribution

Hence only part d gives the right answer.

F(x)=4x-3<br> G(x)=x^3+2x<br> Find (f-g)(x)
dexar [7]
You gotta remember that (f-g)(x) means f(x) - g(x).

So, in this case, f(x) is [4x - 3], g(x) is [x^3 + 2x].
So that : f(x)-g(x) = [4x-3] - [x^3+ 2x] = -x^3 + 4x - 2x - 3 = -x^3 + 2x - 3

Which is an equation in point-slope form for the given point and slope?
Kisachek [45]

The point-slope form: y-y_1=m(x-x_1)

Q2.

(1,\ -7)\to x_1=1,\ y_1=-7\\m=1\\\\y-(-7)=1(x-1)\\\\y+7=(x-1)

Q3.

(5,\ 9)\to x_1=5,\ y_1=9\\m=2\\\\y-9=2(x-5)

Q4.

y=mx+b\\\\(0,\ 1)\to b=1\\\\y=mx+1

The formula of a slope: m=\dfrac{x_2-x_1}{y_2-y_1}

((-2,\ 4)\to x_1=-2,\ y=4\\(2,\ -2)\to x_2=2,\ y_2=-2\\\\m=\dfrac{-2-4}{2-(-2)}=\dfrac{-6}{4}=-1.5

y=-1.5x+1
