The sum of two numbers is 52. The greater number is 4 more than the smaller number. Which equation can be used to solve for the smaller number? (5 points)

Select one:
a. x − (x + 4) = 52
b. x + (x + 4) = 52
c. x(x + 4) = 52
d. x(x − 4) = 52

Answers

Should be B

Because if it were C or D it would be the product and not the sum
b

if the smaller number is 4 more it can be represented as x+4 and then you add x to the greater number to get 52 which is why the equation is x+(x+4)=52

(answer this and show your work please thank you)
The original height was _answer this_ feet.

please help me with this thank you

Answers

Answer:

9670 feet

Step-by-step explanation:

The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?

we translate word problem to equation.

8219.5 IS 85% of TOTAL

Firstly, 85% = 85/100 = 0.85

Remember, is means =

of means multiplication

So we have:

8219.5 = 0.85 * Total

Hence, total = [let total be 7]

8219.5 = 0.85 * t

t = 8219.5/0.85 = 9670 feet

1. How many cars per day does Car Mart sell? How did you use the table to find this rate?
2. How many cars per day does Winston's sell? Explain how you found this rate.
3. Which dealership sells more cars per day? How many more?
4. Which dealership started with more cars? How many more cars did that dealership start with?
Explain how you found your answer.

Answers

1. Car Mart sell 11 cars per day.
You can use the table by looking at day 2 and day 3. You can see underneath it, it shows how many cars is left after that particular day. So from day 2, you have 43 cars left and day 3, you got 32 cars left. From 43 car to 32 car is losing 11 car. So each day the Car Mart sell 11 car.

2. First we know that after 3 days, Winston have 32 cars left and after 5 day, it has 12 cars left.
Here’s the chart that I made for Winston:
Each day, Winston’s sell 10 cars. (Lose 10 cars per day)

1. Car Mart sells 11 cars a day.

2. Winston's sells 10 cars per day.

3. Car Mart sells one more car per day.

4. Winston started with more cars.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Rate for Winston auto dealer is (32 - 12)/(3 - 5) = - 10.

Rate for cart mart is (32 - 43)/(3 - 2) = - 11.

Car Mart sells 11 cars a day.

Winston's sells 10 cars per day.

Car Mart sells more cars per day.

As cart mart has 43 crs left on the second day he must had 10 more cars on the starting day which is 53.

As Winston had 32 cars on the 3rd day it must had (32 + 11 + 11 ) = 54 cars on the started day so Winston started with more cars.

Track teaches you to be able to achieve your best speed in one of the quickest ways possible. The activity supports the skill because the more mitochondria you have, the more energy you are able to produce during exercise, which will enable you to run with greater speeds. If track is done regularly, it increases the size of the mitochondria. Giving you more energy, which will generate more speed. ( Hope this helps! (: )

Step-by-step explanation:

The graph of the function y = 2x⁴ - 5x³ + x² - 2x + 4 is plotted and attached.

What is a polynomial?

Polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). For example -

y = 4x⁴ + 3x³ + 2x² + 6x + 7

We have the following polynomial functions -

f(x) = 2ˣ

g(x) = f(x - 3) + 4

We can write g(x) as -

g(x) = 2ˣ ⁻ ³ + 4 = (2ˣ/2³) + 4

g(x) = (2ˣ/8) + 4

The graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards.

Therefore, the graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards to given the function g(x)

What is the Inverse Operation of a Square Root ?

Answers

Answer:

The inverse is squaring a number

Step-by-step explanation:

i hope this helps

Power is the result of multiplying two numbers together. The inverse operation of a square root is a square.

What is power?

Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

The radical is the symbol that is used to represent the root in the expression n√x. When the value of n in this radical is 2, then it is known as the square root.

The inverse operation of a square root is a square, which means that the expression is needed to be multiplied by itself.

Hence, The inverse operation of a square root is a square.
