16+90+2y =180 since it is a straight line

106 +2y = 180

subtract 106 from each side

2y = 74

divide by 2 on each side

y=37

90+2y+O = 180 since it is a straight line

90 + 2(37) +O = 180

90+74 +O = 180

164+0 =180

subtract 164 from each side

O = 16

O +4x+90=180 sine it is a straight line

16 + 4x +90 = 180

106 +4x = 180

subtract 106 from each side

4x = 74

divide by 4

x=18.5

What is the domain and range of f(x)=2.5x when x goes up to 800

Mandarinka [93]

Answer:

Domain: all real numbers. Range: (-∞, 2000]

Step-by-step explanation:

f(x)=2.5x is a simple "ramp" function, a linear function and a polynomial. As such, its domain contains "all real numbers." That value 800 defines the largest value that this f(x) can have: f(800) = 2.5(800) = 2000.

Thus, the range is "all real numbers from -∞ through and including 2000."

Lisa has 12 more stickers than John, and together they have 60 stickers. What is the ratio of the number of Lisa’s stickers to t

Harman [31]

Answer:

The ratio of the number of Lisa’s stickers to the number of John’s stickers is 3/2

Step-by-step explanation:

Step 1

Let

x ----> the number of stickers that Lisa has

y ----> the number of stickers that John has

we know that

$x+y=60$ ------> equation A

$x=y+12$ ----> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

$(y+12)+y=60\\ 2y=60-12\\ 2y=48\\ y=24$

Find the value of x

$x=y+12$ -----> $x=24+12=36$

therefore

Lisa has 36 stickers and John has 24 stickers

Step 2

Find the ratio of the number of Lisa’s stickers to the number of John’s stickers

x/y

substitute

$\frac{36}{24}=\frac{3}{2}$
