Which ordered pair is a solution of the equation?3x+3y= -x+5y

a) only (1,2)
b) only (2,4)
c) both (1,2) and (2,4)
d) neither

Answers

Answer 1
Answer:

First simplify the equation.

3x+3y= -x+5y

4x=2y

2x=y

y=2x

Means that the y value is 2 times the x value.

answer: C but there are more solutions than just (1,2) and (2,4)

A parallelogram has sides measuring 23.8 m and 35.3 m. The height corresponding to the 23.8-m base is 9.9 m. Find the height, to the nearest tenth of a meter, corresponding to the 35.3-m base.

Answers

Answer:

The value of x i.e DE is6.7m^2

Step-by-step explanation:

Given a parallelogram has sides measuring 23.8 m and 35.3 m. The height corresponding to the 23.8-m base is 9.9 m. we have to find the height corresponding to the 35.3-m base which is DE

Area of parallelogram ABCD=Base AB* heightDE

                                               =35.3* x

                                               =35.3x m^2

Area of parallelogram ABCD=Base BC* heightDF

                                               =23.8* 9.9

                                               =235.62 m^2

Above two is the area of same parallelogram

⇒ 35.3x=235.62

⇒  x=6.6747\sim6.7m^2

Hence,The value of x i.e DE is6.7m^2

How do you get an odd perimeter for a rectangle? If you can, how oils you get a length and a width?

Answers

An odd perimeter can only happen if either the length or the width is a fraction with 1/2 in it, or both the length and the width have a 1/4 in it.
The length and the width are found using the regular means, but you will have to worry about fractions involved, so it can get kind of messy

B. The y-intercept is (0, 1).
C. It is always increasing.
D. The domain of f(x) is x>0

Answers

The y-intercept of the function will be (0, 1). Then the correct option is B.

What is a function?

A statement, principle, or policy that creates the link between two variables is known as a function.

The function is given below.

f(x) = (9/10)ˣ

For the y-intercept, the value of x will be 0.

f(0) = (9/10)⁰

f(0) = 1

The y-intercept of the function will be (0, 1).

Then the correct option is B.

More about the function link is given below.

Marissa researched the cost to have custom T-shirts printed by several local and online vendors. She found that each store’s charge for the job could be modeled by a linear function that combined a flat charge for artwork with a per T-shirt rate. Marissa plotted the functions on a coordinate grid and found that two of the functions produced lines that had the same y-intercept. How should Marissa interpret this result?A.Those two vendors charge the same rate per shirt.B.Those two vendors charge the same flat rate for artwork.C.Those two vendors will have the same total cost to produce one shirt.D.Those two vendors will charge the same total cost for any size job.
