The sum of three times a number and 8 is –22. What is the number?1.)–10
2. )10
3. ) –5
4.) 5
Can someone help please.

Answers

If you subtract 8 from -22 and then divide by 3 you get the answer, -10

Let's take this phrase by phrase.

sum of three times a number and 8 = 3x + 8
Whenever there is a term mentioned without a definite value, we can represent it with a variable. In this case, I represented the number with "x".
is -22 means =-22
What equals -22? The sum of three times a number and 8 equals -22.
3x + 8 = -22
Subtract both sides by 8
3x = -30
x = -10

Final Answer: 1) -10

The table shows the cost of renting movies online. Number of Movies Cost 1 $3.99 2 $7.98 3 $11.97 4 $15.96 5 $19.95 What does the rate of change mean in this situation? A. The cost increases $3.99 for every additional movie rented.
B. The cost increases $15.96 for every additional movie rented.
C,The cost increases $7.98 for every additional movie rented.
D.The cost increases $11.97 for every additional movie rented

Answers

Answer: A

Step-by-step explanation: If you subtract each price by the price lower then it. Ex: $19.95 - $15.96 = $3.99, $15.96 - $11.97 = $3.99 and so on. They all equal $3.99.

Answer:

A. The cost increases $3.99 for every additional movie rented.

Verify: (sinx+cosx)^2=1+sin(2x)

Answers

(sinx + cosx)² = 1 + sin(2x)

Since (a + b)² = (a + b)(a+b):
(sinx + cosx)(sinx + cosx) = 1 + sin(2x)

Now, multiply each member with another:
sin²x + sinxcosx + sinxcosx + cos²x = 1 + sin(2x)
⇒ sin²x + cos²x + 2sinxcosx = 1 + sin(2x)

Since sin²x + cos²x = 1 (Pithagorean identity):
1 + 2sinxcosx = 1 + sin(2x)

Since 1 + 2sinxcosx = 1 + sin(2x) (Double-angle identity):
1 + sin(2x) = 1 + sin(2x)

What is the circumference of 59 inches

Answers

By circumference we can safely assume that the figure is a circle. Assumingthat the given is radius, you are given the radius of a circle of 59 inches. Youare asked to find the circumference of the figure. The equation for thecircumference of a circle is C=2*pi*r.

C=2*pi*r
C = 2*3.723*59 inches
C = 370.71 inches
The circumference of a circle is 370.71 inches.

Andre bought a new bag of cat food. The next day, he opened it to his cat. The graph shows how many ounces was left in the bag on the days after it was bought. How many ounces of food were in the bag 24 days after Andre bought it?

Answers

16 ounces of cat food was in the bag, on 24th day

Given : The y axis represents dependent variable ie the 'ounces of cat food' , and x axis represents independent variable ie 'days since bag was bought'

To find : Value of y ie ounces of food - on a particular value of x ie days since bag bought , we draw a straight vertical line from value of x to the curve & correspond it to y axis.

From x = 24, if we draw a straight vertical line to the graph - it touches the point ( x,y ) = (24, 16). Extending it further to y axis, we get value of y ie 'ounces of food' = 16

Answer:

There were 16 ounces of Cat Food after 24 days.

Step-by-step explanation:

From the graph attached,

For an ordered pair (x, y) lying on the graph,

x-coordinate represents the number of days since bag was bought and y- coordinate represents the ounces of cat food required.

Now the value x = 24 on x-axis shows the number of days since the bag was bought.

For x = 24, ounces of cat food in the bag ( y ) = 16 ounce

Therefore, 16 ounces of Cat Food were in the bag after 24 days since it was bought.
