Step-by-step explanation:

f (x)=5x+1

Hence, In order to find f (-3), we must find the value of 5×-3 +1

Hence, Substituting x=-3,

p (-3)=5×-3 +1

= -15+1

= -14

Hi there! :)

Answer:

[tex]\huge\boxed{z = 8}[/tex]

-2(z - 9) = 2

Divide both sides by -2:

-2(z - 9) / (-2) = 2/ (-2)

z - 9 = -1

Add 9 to both sides:

z = -1 + 9

z = 8.

Answer:

both y --> -∞

Step-by-step explanation:

1. x--> -∞

=> x-1 --> -∞

=> |x-1| --> ∞

=> - |x-1| --> -∞

=> y --> -∞

2. x --> ∞

=> x-1 --> ∞

=> |x-1| --> ∞

=> -|x-1| --> -∞

=> y --> -∞

Answer:

Step-by-step explanation:

If point D is between C and R, then the vector CD = DR is true. Given the following parameter CD = 6x-8 meters, DR = 4 meters, to get the value of X we will equate both vector functions as shown;

6x-8 = 4

add 8 to both sides

6x-8+8 = 4+8

6x = 12

divide both sides by 6

6x/6 = 12/6

x = 2

Hence the value of x in metres is 2 metres.

Answer:

18km/h

Step-by-step explanation:

72/4=18

speed = distance/time

Answer:

As we can see, what we are doing is substracting 4 from one term to the next:

22 - 4 = 18

18 - 4 = 14

14 - 4 = 10

10 - 4 = 6

Knowing this and that we start on 22, we can say that for n term we have:

[tex]22-4(n-1)[/tex]

So, if we're searching the thirs term, we replace n by 3 (we can also see it in the question):

[tex]22-4(n-1)[/tex] = [tex]22-4(3-1) = 22-4*2 = 22 - 8 = 14[/tex]

So the third term is 14.

Answer:

reflection in the y- axis

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y )

Note the x- coordinate is opposite in sign and the y- coordinate remains unchanged.

Thus

(- 4, - 6 ) → (4, - 6 )

(- 6, 4 ) → (6, 4 )

The endpoints have been reflected in the y- axis

We want to see which reflection we need to use to transform the given segment into the desired one.

The correct answer is:

"a reflection of the line segment across the y-axis"

First, we want to change the segment with endpoints at (-4, -6) and (-6, 4) to a segment with endpoints (4, -6) and (6, 4).

Note that the only thing that changes is the x-value of the endpoints, so we need to apply a reflection that only changes the x-value.

That reflection is a reflection across the y-axis.

For a general point (x, y), a reflection across the y-axis transforms the point to (-x, y).

Then the correct option is:

"a reflection of the line segment across the y-axis"

Answer: C

Step-by-step explanation:

The distance between numbers is the difference between them.

5/2 and  4 7/8  

Using these pints the distance will be

5/2 - [tex]4\frac{7}{8}[/tex]   is the same as -5/2 - 4 7/8  

and is also not the same as 5/2 - (-4 7/8)

Answer:

C) None of the above

Step-by-step explanation:

The distance between 5/2 and 4 7/8 is 4 7/8-5/2= 39/8-20/8=19/8=2 3/8

A) |-5/2-4 7/8|=|-20/8-39/8|=|-59/8|=59/8= 7 3/8 SO NO

B) |5/2-(-4 7/8)|=|20/8+39/8|=|59/8|=59/8= 7 3/8 SO NO

C) None of the above = YES

Answer:

X = 28+3(6)

X = 28 +18

X = 46

Thus, the value of X will be 46.

Hope it helps.

Answer:x = 36

Step-by-step explanation:

First you would multiply 3(6) which equals 18

Then, you would add 18+28 which gives you 36

SO 36 would be your answer

Answer:

It is a rational number

Step-by-step explanation:

3/8 = 0.375

The set of rational numbers is of measure zero on the real line, so it is "small" compared to the irrationals and the continuum.

Any rational number is trivially also an algebraic number.

Step-by-step explanation:

Hey, there!!

Let's solve it simply.

Given,

11 - 13x - 7 - 2x = 7

Simplify the like terms.

11 - 7 - 13x - 2x = 7

4 - 15x = 7.

shifting 4 in right side.

-15x =7-4

-15x = 3

Divide 3 by -15.

[tex]x = \frac{3 }{ - 15} [/tex]

Therefore, x = (-3/15) or (-1/5).

Answer:

[tex]g(f(2))=3[/tex]

Step-by-step explanation:

So we have:

[tex]f(x)=4x-3\text{ and } g(x)=\frac{2x-1}{3}[/tex]

And we want to solve for g(f(2)).

First, find f(2):

[tex]f(2)=4(2)-3[/tex]

Multiply:

[tex]f(2)=8-3[/tex]

Subtract:

[tex]f(2)=5[/tex]

Now, substitute this in for g(f(2)):

[tex]g(f(2))=g(5)[/tex]

Substitute this in for g(x):

[tex]g(5)=\frac{2(5)-1}{3}[/tex]

Multiply:

[tex]g(5)=\frac{10-1}{3}[/tex]

Subtract:

[tex]g(5)=\frac{9}{3}[/tex]

Divide:

[tex]g(5)=3[/tex]

Therefore:

[tex]g(f(2))=3[/tex]

Answer: 5.32

Step-by-step explanation:

8/25 as a decimal is 0.32. Add the fraction and whole number and you get 5.32

Answer:

5.32

Step-by-step explanation:

We know that the 5 in [tex]5 \frac{8}{25}[/tex] will just be a 5, so we can leave that be for now.

Since we have [tex]\frac{8}{25}[/tex], we want to turn it into a decimal.

A way of representing decimals is [tex]\frac{x}{100}[/tex], like [tex]\frac{69}{100}=0.69[/tex].

Therefore, we can convert  [tex]\frac{8}{25}[/tex] into hundredths and find the decimal that way.

[tex]\frac{8}{25} = \frac{x}{100}[/tex]

We can cross multiply to find the value of x.

[tex]100\cdot8=800\\\\800\div25=32[/tex]

This means that [tex]\frac{8}{25} = \frac{32}{100}[/tex]. This means the decimal is 0.32.

Adding the 5 to it, we get 5.32.

Hope this helped!

Answer:

x = 10.75

Step-by-step explanation:

To find the value of x, we need to know the equation for the perimeter of a rectangle.  This equation is:

P = 2L + 2W

Where P is the perimeter, L is the length, and W is the width.

We are given P = 84, L = 3x -1 , and W = x.  Now we just plug these values in and solve for x.

P = 2L + 2W

84 = 2 ( 3x - 1 ) + 2 ( x )

84 = 6x - 2 + 2x

84 = 8x - 2

86 = 8x

86 / 8 = x

43 / 4 = x

(40 + 3) / 4 = x

10.75 = x

Hence, the value of x = 10.75.
