X + y = 4
<span>y = x + 4

</span>x + (x + 4) = 4
y = x + 4

2x + 4 = 4 
y = x + 4

2x = 4 - 4 
y = x + 4 

x = 0
y = 0 + 4

x = 0 
y = 4

A sculpture of a clothespin is 20 feet high. A normal clothespin of this shape is five inches high. Using this scale, how many f
kodGreya [7K]
This is the concept of scale factor. The linear scale factor is given by:
(height of sculpture)/(height of clothespin)
=20/(5/12)
=48
Given that a woman is 5ft 7 in, the sculpture of this woman would be:
height of sculpture=(scale factor)*(height of the woman)
height of the woman=5 ft 7 inches=5 7/12 ft=67/12 ft
hence the height of the sculpture will be:
67/12×48
=268 ft

Answer: 268 ft

Black_prince [1.1K]

Divide the miles by the gallons used for each car to find the miles per gallon, then compare them:

Blue car: 18 2/5 miles / 0.8 gallons = 23 miles per gallon.

Red car: 17 2/5 miles / 0.7 gallons = 24.86 miles per gallon.

The red car can travel farther on 1 gallon of gas.

Are y=2x+6 and 6t=2x+9 perpendicular
babymother [125]

Answer:

The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Using the slope-intercept form, the slope is 2 2 . The equation of a perpendicular line to y=2x+9 y = 2 x + 9 must have a slope that is the negative reciprocal of the original slope.

Missing: 6t= ‎| Must include: 6t=
