Answer:

x≥−8

Step-by-step explanation:

x/2≥−4

Multiply each side by 2

x/2 * 2≥−4*2

x≥−8

Answer: A

Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3

The inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.

inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

The inequality 3(x-1) ≤ 4x will be solved as below:-

3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3. The complete  solution is given below:-

3(x-1) ≤ 4x

3x - 3 ≤ 4x

-3 ≤ 4x - 3x

-3 ≤ x

x ≥ -3

Therefore, the inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.

Explanation :

I took the test

Answer

13x-37=112

13x =149

X=11.4

2y+7=41

Y=24

The value of x and y respectively will be 13° and 17°.

Based on the equation that's given in the question, the value of x will be found thus:

13x - 37 = 112

Collect like terms

13x = 112 + 37

13x = 149

x = 149/13

x = 13

Also, note that 2y + 7 = 41, therefore, the value of y will be:

2y = 41 - 7

2y = 34

y = 34/2 = 17°

Therefore, the value of x and y respectively will be 13° and 17°.

M=y2-y1/x2-x1

Answer:

4/3

Step-by-step explanation:

Use the formula

x2-x1 over y2-y1

since it goes by (x,y) label the given points

(6,7) and (10,10)​

6 is your first x (x1)

7 is you first y (y1)

onto the next point...(10,10)

10 would be your second x (x2)

and your second y would also be 10 (y2)

Now plug into formula x2-x1 over y2-y1

10-6 over 10-7= 4/3

j=3+25, here's the equation

Step-by-step explanation:

J=28

Answer:

j = 28

Step-by-step explanation:

Since we know that j is 25 more than 3, then we must know that 3+25= J (because J is 25 more/+ than 3) So, we simply solve 25+3 which equals 28.

Answer:

Step-by-step explanation:

Let x be the number of cell phones with keyboards needed.

40% = [tex]\frac{40}{100}[/tex]

[tex]\frac{x+45}{x+120}[/tex] = [tex]\frac{40}{100}[/tex]

x+45 = 40 -----1

x+120 = 100 -----2

You would want to make the total of 1 the same as 2.

1×[tex]\frac{100}{40}[/tex]: 2.5+112.5 = 100 -----3

Now 2 and 3 are equal.

x+120 = 2.5x+112.5

Isolate the x and numbers.

120-112.5 = 2.5x-x

Simplify.

1.5x = 7.5

x = [tex]\frac{1}{1.5}[/tex] × 7.5

x = 5

The manager of the store needs to add 5 more cell phones with keyboards.

Answer:

y= -2x + 80

Step-by-step explanation:

First, you need to find the slope, which can be done by subtracting the change in y over the change in x. The easiest points to pick are (30,20) and (40,0). Do 20-0 which is -20, then divide that by 40-30, and you get -2. Then to find the y intercept, pick a point (like 40,0). Then do 0 = -2(40) + b, and solving for b you get 80.

Step-by-step explanation:

The graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

Given that,
To determine the graph of the polynomial function h(x) =  x³ + 2x² - 11x -12.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
The graph of the function h(x) = x³ + 2x² - 11x -12 can be drawn as the function is a polynomial of degree 3 so it will follow two ups  and down,
So the graph can be drawn as shown in the image.

Thus, the graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

Answer:

[tex]6\frac{2}{3}[/tex] %

Step-by-step explanation:

First, convert 3 meters into centimeters.

1m = 100cm

3m = 100 × 3 = 300cm

Now, form the fraction by putting the given value, 20cm, over the total measurement, 300cm.

[tex]\frac{20}{300}[/tex] = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex]  ⇒ Simplify your fraction to its simplest terms.

Next, multiply your simplified fraction by 100 to get your percentage.

[tex]\frac{1}{15}[/tex] × [tex]100[/tex] = [tex]\frac{100}{15}[/tex] = [tex]6\frac{10}{15}[/tex] = [tex]6\frac{2}{3}[/tex] %   ⇒ Simplify your percentage to its simplest terms.
