Question 6 (1 point)

Mathematics
1 answer:
nikklg [1K]3 years ago
5 0

Answer:

y=-8 and x =3

Step-by-step explanation:

4x - y = 20 and -2x - 2y = 10

if we multiply the second equation by -2 we have:

4x + 4y = -20 and 4x - y = 20

we subtract the two equations and we have

5y = -40 so y=-8 which means x= 3

The value of a professional basketball player's autograph rose 40% in the last year. It is now worth $294.00.
ZanzabumX [31]
I'll assume you're asking for the initial price

Let's use x to represent it
The initial price plus 40 percent of that is $294

Let's write that out mathematically

x + (40/100)x = 294
x + 0.4x = 294
1.4x = 294
x = 210

The initial price is $210

(-2,9) and (-2,-5)<br> Slope:
Oliga [24]

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (- 2, - 5 )

m = \frac{-5-9}{-2-(-2)} = \frac{-14}{-2+2} = \frac{-14}{0}

Since division by zero is undefined then the slope is undefined

Order the subjects from least to greatest art for 25th English 13% math 0.28 other 7% science 21 over 100 social studies 0.15
Airida [17]

Answer:

Other, English, Social Studies, Art, Science, Math

Step-by-step explanation:

Let's start by tking each subject and putting them in decimal form, so that way we have an accurate way to see which is truly greater.

Art is 4/25, so to get the denominator up to 100 (the number it needs to be at to convert to decimal form). You have to times 25 by 4, and also 4 by 4. You get 16/100, which is .16 in decimal form.

English is 13%, or 13/100. Just convert it to decimal and you get .13

Math is already at .28

Other is at 7%, or 07/100. In decimal form, .07

Science is 21/100, and in decimal form, .21

Social studies is in decimal form at .15

You now have the numbers .16, .13, .28, .07, .21, and .15

Just put these in order and you get:

.07, .13, .15, .16, .21, .28

Other, English, Social Studies, Art, Science, Math
