Which ordered pair makes both inequalities true?

y > –3x + 3

y > 2x – 2


(1,0)
(–1,1)
(2,2)
(0,3)

Answer:

option d

Step-by-step explanation:

Solve each inequality and check which inequality has -12 as a solution

a. [tex]x+6<-8[/tex]

Subtract 6 from both sides

[tex]x<-14[/tex]

b. [tex]x+4>-6[/tex]

Subtract 4 from both sides of the inequality to get x alone

[tex]x>-10[/tex]

c.[tex]x-3>-0[/tex]

Add 3 on both sides

x>3

d. [tex]x+5<-4[/tex]

Subtract 5 from both sides

x<-9

-12 lies below -9. So x<-9 has -12 in its solution

A

f(x) = 2x + 1

f(3) = 2*3 + 1 = 7

B

g(x) = x^2

g(7) = 7^2

g(7)= 49

C

f(g(x)) = 2(g(x) + 1

f(g(x)) = 2 x^2 + 1

f(g(3) = 2* 3^2 + 1

f(g(3) = 19

D

g(f(x)) = (f(x))^2

g(f(x)) = (2x + 1)^2

g(f(3)) = (2*3 + 1)^2 = (6 + 1)^2 = 49

E

f(g(x)) = 2*g(x) + 1

f(g(x)) = 2*x^2 + 1

f(g(3)) = 2*3^2 + 1

f(g(3)) = 2 * 9 + 1

f(g(3)) = 18 + 1

f(g(3) = 19

F

f(g(x)) = 2(g(x)) + 1

f(g(x)) = 2*x^2 + 1

Answer:

40th customer

Step-by-step explanation:

Given that there is a promotional event

A sporting good store gave t shirt and free water bottle.

T shirt was given to 8th customer and water bottle to every 10th customer.

For the first person who should get both, he should have number as least common multiple of 8 and 10

8 = 2x2x2

10 = 2x5

Hence least common denominator = 2x2x2x5 = 40

Thus 40th customer will be the first to get both.

Your answer would be D, The translation doesn't change the size or shape. Just location.

Hope this helped.

So, the product of (9x - 2)(3x - 8) in standard form is: [tex]27x^2 - 78x + 16[/tex]

To multiply the expressions (9x - 2) and (3x - 8)

Step 1: Use the distributive property

(9x - 2)(3x - 8) = 9x * (3x) + 9x * (-8)

(9x - 2)(3x - 8) = -2 * (3x) - 2 * (-8)

So , perform the multiplications:

Multiply the terms:

[tex]9x * 3x = 27x^2[/tex]

9x * (-8) = -72x

-2 * 3x = -6x

-2 * (-8) = 16

Combine like terms:

[tex]27x^2 - 72x - 6x + 16[/tex]

Simplify further by combining like terms:

27x^2 - 78x + 16

So, the product of (9x - 2)(3x - 8) in standard form is: [tex]27x^2 - 78x + 16[/tex]

We are given a figure where M, N , O and P points are given.

We need to explain if points O, N, and P collinear or not.

Note: All co-linear points are in a straight line.

From the figure, we can see that O and N points are in a straight line but point P is aside.

So, the points O, N, and P are not collinear.

Therefore, correct option is "No, the three points are not collinear".

Answer:

As mention in the explanation steps.

Step-by-step explanation:

The following expression or phrase to each box are helpful to complete the proof.

(1). We say that ∠ACB and ∠BCD are supplementary, from linear pair of postulate.

(2). ∠ACB + ∠BCD =180°, because ∠ACB and ∠BCD are supplementary (from the difinition of supplementary angles).

(3). ∠ACB +45° = 180° because ∠BCD =45°(substitute).

(4).Subtraction properties of equality ( because we subtract 45 degree from both sides of the previous equation).

(5). ∠ABC is obtuse, because m∠ABC grater than 90°.

(6). From the definition of obtuse triangle (ΔACB is an obtuse triangle because ∠ACB =135 degree which is grater than 90 degree).

Apply the vertical line test. Think of a vertical line moving from left to right in the graph. If the graph of the relation intersects the vertical line in more than one point in any position of the vertical line, then the relation is not a function.

The only graph that passes the vertical line test is the graph at the bottom right.

The graph at the bottom right is a function. All others are not.

Answer:

The man got a 8% raise.

Step-by-step explanation:

Percentage change        = [Increase or decrease in value / Original Value]*100

Increase in hourly wage = [tex]13.5-12.5[/tex]

                                         =[tex]1[/tex]

Percentage raise             = [Increase in hourly wage / Initial hourly wage]*100

                                         =[tex]\frac{1}{12.5} *100[/tex]

                                         = [tex]8[/tex]%

The man got a 8% raise.

The man's hourly wage increased from $12.50 to $13.50 which, following the formula for calculating percentage change, indicates that he received an 8 percent raise in his hourly wage.

Given that the man's hourly wage increased from $12.50 to $13.50, we can use the formula for calculating the percentage change to find out what percent raise he got.

The formula for calculating the percentage change is as follows:

[(change in quantity)/(original quantity)] × 100

In this case, the change in quantity (the man's wage increase) is $1.00 (13.50 - 12.50), and the original quantity (the man's original wage) is $12.50.

Plugging these values into the formula, we get:

[1.00/12.50] × 100

This calculates to an 8 percent wage increase. Therefore, the man got an 8 percent raise in his hourly wage.

(2x+1)+89=180.  180 is the angle of a straight line.  Set your two known sides equal to 180 and solve for x if needed.

Answer:

24 ounces.

Step-by-step explanation:

Given that the ratio of blue paint to yellow paint in a green paint mixture is 2:3.

Actual ounces used for blue paint = 16

By ratio and proportion property we have

2:3 = 16:x where x is the actual ounces of yellow paint used.

Simplify using ratio rules

if a:b = c:d then ad = bc

We get

2x=3(16) = 48

Divide by 2

x = 24

Hence 24 ounces of yellow paint to be used.

Answer:

24 ounces. to be exact

Step-by-step explanation:

Remember that when two angles are vertical angles, their angle measurements are the same, as the angles are congruent.

Note the Vertical Angle Theorem. Angles vertically opposite (directly opposite) when two lines intersect are congruent with each other.

Now note that supplementary means 180°

Set the equation. Let the angles = x

2x = 180

Isolate the x. Note the equal sign. What you do to one side, you do to the other. Divide 2 from both sides

(2x)/2 = (180)/2

x = 180/2

x = 90

90° is the measurement of each angle.

Answer: x = -1, -3, 7 + √62, 7 - √62

Step-by-step explanation:

q                                    p

x⁴ - 10x³ - 66x² - 94x - 39

[tex]\frac{p}{q}[/tex] = +/- [tex]\frac{1*3*13*39}{1}[/tex]

possible rational factors: 1, -1, 3, -3, 13, -13, 39, -39

Use synthetic division or long division to see which factor will leave a remainder of 0.

try x + 1 = 0  ⇒   x = -1

-1   |  1     -10     -66     -94     -39

    |  ↓     -1        11        55      39

       1     -11      -55     -39       0

(x + 1)(x³ - 11x² - 55x - 39)        

next, try x + 3 = 0  ⇒   x = -3   for the new polynomial

-3   |  1     -11     -55     -39

     |  ↓     -3       42     39

        1     -14      -13       0  

(x + 1)(x + 3)(x² - 14x - 13)

Lastly: find the zeros by setting each factor equal to zero and solve.

x + 1 = 0  ⇒  x = -1

x + 3 = 0   ⇒ x = -3

x² - 14x - 13 = 0

[tex]x = \frac{-(b) +/- \sqrt{(b)^{2} -4(a)(c)}}{2(a)}[/tex]

  [tex]= \frac{-(-14) +/- \sqrt{(-14)^{2} -4(1)(-13)}}{2(1)}[/tex]

  [tex]= \frac{14 +/- \sqrt{196+52}}{2}[/tex]

  [tex]= \frac{14 +/- \sqrt{248}}{2}[/tex]

  [tex]= \frac{14 +/- 2\sqrt{62}}{2}[/tex]

  [tex]= 7 +/- \sqrt{62}[/tex]

[tex]5\cdot5\cdot4\cdot4\cdot3\cdot3\cdot2\cdot2\cdot1\cdot1\cdot2=28,800[/tex]

Starting with 113+ (2x+5)=180, combine like terms and to get 118+2x=180.  Subtract 180-118, which gives you 62.  Then you have 2x=62.  Divide both sides by 2 to get a final answer of x=31.

Hey there!!

Given :

... 113 + ( 2x + 5 ) = 180

Subtract 113 on both sides

... 2x + 5 = 180 - 113

... 2x + 5 = 67

Subtract 5 on both sides

... 2x = 62

Divide by 2 on both sides

... x = 31

The value of x is 31.

If you can maintain this speed you will travel 120 km in 1 hour.

Explanation:

The translated question is, A cheetah can travel 20 kilometers in 10 minutes. If I could maintain this speed for one hour, how many kilometers would you travel?.

 Let us find the speed of cheetah

            Distance traveled =  20 km

            Time taken = 10 minutes = 10/60 = 1/6 hours

            So speed = [tex]\frac{20}{\frac{1}{6} } =120[/tex]km/hr.

 So speed of cheetah = 120 km/hr, which means cheetah will travel 120 km in 1 hour.

If you can maintain this speed you will also travel 120 km in 1 hour.
