What is the answer for -3 > -2x + 7

Answers

−3>−2x+7

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

−2x+7<−3

Subtract 7 from both sides.

−2x<−3−7

Subtract -7 from −3 to get −10.

−2x<−10

Divide both sides by −2. Since −2 is negative, the inequality direction is changed.

Here we start with a function f(x), and we also have the graph of this function.

And we want to find the graph of the function defined as:

g(x) = f(x + 1) - 3

Notice that:

g(x)=  f(x + 1)

Is a translation of one unit to the elft of f(x).

g(x) = f(x) - 3

Is a translation of 3 units down of the graph of f(x).

Then:

g(x) = f(x + 1)- 3

Is a translation of one unit to the left and 3 units down.

With that in mind, we can see that the correct option for the graph of g(x) is option B.

Ratio expresses the relationship between two or more numbers. It is the number of times that one value is contained within other value(s).

The ratio of snakes to frogs can be determined by counting the number of snakes and frogs.

Number of snakes = 4

Number of frogs = 8

The ratio of snakes to frogs - 4 : 8 = 1 : 2

The ratio of frogs to animals = number of frogs : number of animals = 8 : 12 = 2 : 3.

Number of snakes if 3 more are added = 4 + 3 = 7

Ratio of snakes to frogs - 1 : 2  

Number of frogs that would keep the ratio constant = 7 x 2 = 14

2x+28x+48= 30x+48=60+48=108

when x=-3, 11x+6 = -33+6=-27,

2x+28x+48= 30x+48=-90+48=-42

Answer:

I got 28, -27, 108, and -42. See explanation for the answer for which problems

Step-by-step explanation:

11x + 6 = ?

2x + 28x + 48 = ?

x = 2 and x = -3

Let's start with the first equation

Using x = 2

11(2) + 6 = ?

22 + 6 = 28

Using x = -3

11(-3) + 6 =?

-33 + 6 = -27

Second equation

Using x = 2

2(2) + 28(2) + 48 = ?

4 + 56 + 48 = 108

Using x = -3

2(-3) + 28(-3) + 48 = ?

By taking some products we will see that the total number of cupcakes ordered is 6 cupcakes.

How many cupcakes are ordered?

Here we want to see how many cupcakes this person is ordering. We know that orders 9 halves of a cupcake for the family, plus a quarter of a cupcake for each of the 6 friends.

The total number of cupcakes is given by the order for the family plus the order for the friends.

The order for the familiy is given by the product:

9*(1/2) = 9/2 = 4.5

That is 9 times 1/2 of a cupcake, so for the family the person orders 4.5 cupcakes.

For the friends the person orders 6 times 1/4 of a cupcake, so now we have the product:

6*(1/4) = 6/4 = 3/2 = 1.5

If we add these two numbers we get the total number of cupcakes:

4.5 + 1.5 = 6

If one part is randomly selected, find the probability that the part is between 10.8 and 12.8 centimeters.

Answers

The probability that the plant manufactures a part between 10.8 and 12.8 centimeters 13%

How to find the probability that the part is between 10.8 and 12.8 centimeters

The probability is solved z scores, this measures the amount of standard deviation sample X is from mean. the formula is below

z = (X - μ) / σ

Definition of variables

mean, μ = 16.3 centimeters

standard deviation, σ = 2.5 centimeters

X = 10.8 and 12.8 centimeters

z score, z

substituting into the formula

for X = 12.8 centimeters

=  (X - μ) / σ

= (12.8 - 16.3) / 2.5

= -1.4

the p value for z of -1.4 = 0.161513

for X = 10.8 centimeters

=  (X - μ) / σ

= (10.8 - 16.3) / 2.5

= -2.2

the p value for z of -2.2 = 0.027807

the probability is calculated as below

0.161513 - 0.027807= 0.133706

How to calculate the values?

1. Lines 'l' and 'm' are the parallel lines and a transversal line is intersecting these  lines.

(9x + 13)° = (12x - 29)° [Alternate interior angles]

9x - 12x = -29 - 13

-3x = -42

Divide

x = 14

2). By substituting x = 14 in the box.

(13x + 5)° + (8x - 14)° = 180° [Consecutive interior angles]

21x - 9 = 180

21x = 189

Divide

x = 189/21

x = 9

3). By placing x = 9 in the box,

(5x + 52)° = (9x - 16)° [Corresponding angles]

5x - 9x = -52 - 16

According to the question,

[tex]64x^{3} +8[/tex]

The factors of this expression can be found using identity because 64[tex]x^{3}[/tex] is the whole cube of 4x and 8 is the cube of 2.

So, we have the following expression:

[tex](4x)^{3} + 2^{3}[/tex]

Now, we can use the following identity to factor the given expression:

[tex]a^{3} +b^{3} = (a+b) (a^{2} -ab+b^{2} )[/tex]

We have a = 8x and b = 2:

(8x+2) {[tex](4x)^{2}[/tex]-16x+[tex]2^{2}[/tex]}
