Answer:

D. x<-15

Step-by-step explanation:

-3x-42>3   Add 42 to both sides.

  +42 +42

-3x>45      Divide both sides by -3.

/-3   /-3

x>-15         Each time you multiply or divide by a negative, you flip the sign.

x<-15

Hope this helps you out!! Have an amazing day ^^

Answer:

It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis. Notice also that the graphs are exactly the same shape but horizontally shifted /2 units. They are related by: sin (x) = cos (x - /2) and cos (x) = sin (x + /2).

Answer:

136

Step-by-step explanation:

Answer:

13cm

Step-by-step explanation:

The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.

a = 12cm

b = 5cm

c = hypotenuse

[tex]12^{2} +5^{2} =c^{2}[/tex]

[tex]144+25=c^{2}[/tex]

[tex]\sqrt{169} =c[/tex]

13 = c

Answer:

13

Step-by-step explanation:

a^2+b^2=c^2

12^2+5^2=c^2

144+25=c^2

169

square root of 169=13

13=c

Answer:

Step-by-step explanation:

y = (x+1)² - 3

 = (x²+2x+1)-3

 = x²+2x-2

:::::

y = (x-2)² + 3

 = (x²-4x+4) + 3

 = x²-4x+7

Answer:

The length of the rectangle is 28 inches.

Step-by-step explanation:

We have that the width (W) of a rectangle is half of the length (L) of the rectangle:

[tex] W = \frac{1}{2}L [/tex]  (1)

Also, the perimeter is 84 inches:

[tex] P = 2W + 2L = 84 in [/tex]   (2)

By entering equation (1) into equation (2) we have:

[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]

[tex] L = \frac{84}{3} = 28 in [/tex]

Therefore, the length of the rectangle is 28 inches.

The measure of DE is 130 degrees if the measure of DEF is 65 in the circle option (A) is correct.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Circle is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

The measure of DEF = 65 degrees

C is the center.

Angle CED = 90 - 65 = 25 degrees

Angle DCE = 180 - 25 - 25

Measure of DE = 130 degrees

Thus, the measure of DE is 130 degrees if the measure of DEF is 65 option (A) is correct.

THE ANSWER IS -1 OKAYYYYyyyyyyyyyyy. sorry i had to write more than 20 letters

Answer:

20, 68%, 0.687

Step-by-step explanation:

If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.

Answer:

C. r = 28.50 ÷ 3

Step-by-step explanation:

You have to divide to see the rate

Given:

[tex]\to \text{time}= 3 \ hours\\\\\to \text{total eran}= \$28.50 \\\\[/tex]

To find:

earn per hour=?

Solution:

[tex]\to \text{time}= 3 \ hours\\\\\to \text{total eran}= \$28.50 \\\\[/tex]

calculate earn per hour:

[tex]= \frac{\text{total earn }}{ \text{time}}\\\\= \frac{28.50}{3}\\\\= \$ 9.5\\\\[/tex]

Therefore, the answer is "$9.5".

Answer:

g' (×)=f

Step-by-step explanation:

g (×)=f×-7

g' (×)= d÷d× (f×-7)

d÷d×(f+g)=d÷d×(f)+d÷d=(g)

g' (×)=d÷d×(f×)-d÷d×(7)

g'(×)=f-d÷d×(7)

g'(×)=f-0

g'(×)=f
