Evaluate the expression 4x+3-x for
x=8


PLEASE HELP ME!

Let's divide:

4.8 ÷ 2 = 2.4

Another option:

Shift the decimal point one space for both:

4.8  →  48

2.0  →  20

Now we can divide easily:

48 ÷ 20 = 2.4

It will give the same result.

Answer:

The expected number of appearance defects in a new car is 0.64.

Step-by-step explanation:

To find the expected number of appearance defects in a new car, we multiply each outcome by its probability.

We have that:

0.61 probability of 0 defects

0.21 probability of 1 defect

0.11 probability of 2 defects

0.07 probability of 3 defects

0.61*0 + 0.21*1 + 0.11*2 + 0.07*3 = 0.64

The expected number of appearance defects in a new car is 0.64.

Answer:

x^7 = 60

Step-by-step explanation:

log(a)+log(b)=log(ab) so

logx 5 + logx 12 = logx (5*12) = logx 60

logx a = b means x^b = a so x^7 = 60

The logarithm equation in exponential form is x⁷ = 60

An exponential equation that can be represented in the form of abˣ.

The logarithm equation is:

logₓ 5 + logₓ 12 = 7

According to the rule of the logarithm,

log a + log b = log (ab)

logₓ ( 5 *12) = 7

logₓ ( 60) =7

According to the property of logarithm

logₓ ( a) = b

xᵇ = a

x⁷ = 60

Answer:

We conclude that the table C represents a constant change in x and y.

Hence, table C represents that y is a linear function of x.

Step-by-step explanation:

Here are some of the rules using which we can easily figure out the true nature of a function.

Linear Function:

The constant change in x and y

Quadratic Function:

The constant change in x

The constant 2nd differences in y

Exponential Function:

The constant change in x

The constant ratio in y

We have to find a table in which y is a  linear function of x.

Checking the table C

x         -1         0        1         2          3

y         6         8       10        12        14

Here:

There is a  constant change in x.

i.e. 0 - (-1) = 1;  1 - 0 = 1;  2 - 1 = 1;  3 - 2 = 1

Also there is a  constant change in y.

i.e. 8 - 6 = 2;  10 - 8 = 2;  12 - 10 = 2;  14 - 12 = 2

Thus, we conclude that the table C represents a constant change in x and y.

Hence, table C represents that y is a linear function of x.

Step-by-step explanation:

For missing sides of a triangle we do the following.

Does it have a right Angle determine other angle measures, say if an external angle on a straight line showed 145 then its adjoing interior would be 180-145=35 degree.

Are the measure of the lengths congruent with a larger or smaller triangle shown.

If yes then if one triangle showed 4 and same triangle showed 6 and had ne missing, then the other had 8 and 10 and had one missing we would compare and if 8 was the same as 4 we would recognise the congruent triangle is x2 (scale factor 2) so measure 6 woyuld also be measure 12 for the other triangle. and then to find the smaller missing side we see 10 is left over and 10/2 = 5

Other ways to find length is through Pythagoras  we use the squares a^2 + b^2 = c^2 for missing slant

and c^2 - b^2 = a^2 for any missing side

so a represents any missing side for the second equation and c represents the missing side if it is a slant only.

Answer:

62 pages

Step-by-step explanation:

The total cost function is given as below:

C= 0.06p + 12.75

C=total cost for printing= $16.47

0.06= variable printing cost per page

p=number of pages prinited=the unknown

12.75=monthly fixed printing cost

16.47=0.06p+12.75

16.47-12.75=0.06p

3.72=0.06p

0.06p=3.72

p=3.72/0.06

p=62 pages

Answer:

f(g(x)) = 2x - 7

g(f(x)) = 2x - 2

Step-by-step explanation:

basically, you just want to plug in the g(x) function wherever you see an x in the f(x) function

f(g(x)) = 2(x - 5) + 3

         = 2x - 10 + 3

         = 2x - 7

the inverse function is doing the same thing but plugging in f(x) wherever you see an x in the g(x) function

g(f(x)) = (2x + 3) - 5

         = 2x + 3 - 5

         = 2x -2

Answer:

x = 5.57

Step-by-step explanation:

= √8² + 7²

= √64 + 49

= √113

= 10.63

x = √12² - 10.63²

x = √144 - 112.99

x = √31.01

x = 5.568

x = 5.57

Answer:

2y - 15

Step-by-step explanation:

well 15 LESS than TWICE a number. okay so let’s start off by making a variable for the unknown number.... y. the variable is y. so now we have to think, TWICE that number, but we don’t know the number.

Now that we have the variable and we know it has to be doubled, let’s start off making the first half... we can out that into 2y. which is 2 multiplied by the unknown number.

now that we have the first half done, we have to take the 15 less. Less can mean  or subtract in this kind of situation. but for this certain scenario, it will be subtraction. so the equation would be 2y - 15.

Hello!

First of all, let the number be r.

"twice a number" means we multiply that number by 2:

2r

Subtract 15 (fifteen less)

2r-15

This is equal to 21:

2r-15=21

[tex]\rule{160}{2}[/tex]

Solve the equation:

2r=21+15

2r=36

Divide both sides by 2:

r=18

Hope everything is clear.

Let me know if you have any questions!

Answer:

The answer is 384.85 yd       to the power of 3

Step-by-step explanation:

πr2h

=  π×3.52×10

=  122.5π

=  384.85

The volume of the given cylinder would be 384.65 cubic yards.

The volume of cylinder is given by -

V = πR²h

Where -

R - Radius of the cylinder

h - height of the cylinder

Given is to calculate the volume of the cylinder with height 10 yd and diameter 7 yd.

For the given cylinder, we have -

Radius of the cylinder : 7/2 = 3.5 yd

Height of the cylinder : 10 yd

So, we can write the volume of the cylinder as -

V = πR²h

V = 3.14 x 3.5 x 3.5 x 10

V = 384.65 cubic yards

Therefore, the volume of the given cylinder would be 384.65 cubic yards.
