What is the graph of the equation 4x – 5y = 15?
pshichka [43]
4x - 5y = 15
put x=0, 4(0) - 5y = 15
               -5y = 15
               y = -3
coordinates (0,-3)
put y=0, 4x - 5(0) = 15
              x = 15/4
coordinates (15/4,0)
put y=1, 4x - 5(1) =15
              4x = 20
              x = 5
coordinates (5,1)

Plot the three coordinates to obtain a straight line.
Note: You can also use other points rather from what i mentioned.


Hope it helped!

Mrs. Lane took a survey of the types of pants her students were wearing. She collected the data at the right. What percent of he
Nadya [2.5K]

Answer:

It is always important to go through the given problem first to get a concept of the requiremement. Then all the information's available from the question has to be noted down in such a manner that there would be no need to look at the question while solving.

Total number of students wearing jeans = 10

Total number of students wearing shorts = 9

Total number of students wearing capris = 2

Then the total number of students surveyed by Mrs Lane = (10 + 9 + 2)

                                                                                           = 21

Now percentage of students wearing shorts = (9/21) * 100

                                                                      = (3/7) * 100

                                                                      = 300/7

                                                                      = 42.85 percent

So a total percentage of 42.85% of the students were wearing shorts.

Find the value of y. Please help
Alex_Xolod [135]

if the ∡E = ∡F = 90°, that means for that quadrilateral of BEGF, the other angles are ∡B = ∡G = 90°, which means is a square, meaning all its sides are equal, therefore

\bf y + 5 = 3y\implies 5=2y\implies \cfrac{5}{2}=y\implies 2\frac{1}{2}=y
