Answer:
9/4 yards
Step-by-step explanation:
A poster is a rectangle.
Area of rectangle = Length × Width
Given:
Area = 3/4 yd
Length = 1/3 yd
Substitute the given values to the equation.
3/4 = 1/3 × w
3/4 = 1/3w
3/4 ÷ 1/3 = w
3/4 × 3/1 = w
9/4 = w

-20-(4x-1)=-15
-20-4x+1=-15
-20+1+15=4x
-4=4x
x=-1
B
The equation of a line in ' point- slope form ' is
y - b = m( x - a )
where m is the slope and (a, b ) a point on the line
here m =
and (a, b ) = (3, 2 )
y - 2 =
( x - 3 ) → in point- slope form
It would be b. If two numbers are negative and your multiplying them, it would be positive!
10. Kim gets $7 per hour and gets charged $1 for gloves
Use y to represent her pay and x to represent hours worked.
The equation is y = 7x - 1 because she gets 7 times x hours and there is a minus 1 because of the charge of gloves.
11. The table shows that each increasing hour, 8$ is added. Therefore we need to find the bonus that Kit receives just for showing up. This is when hours equals 0. If 3 hours is 27$ pay, then 2 hours is 19$ pay, 1 hour is 11$ pay and 0 hours is 3$ pay. We find that there is a 3$ bonus just for showing up.
Therefore the equation is y = 8x + 3
12. At x = 0, y = 2 so the y-intercept is 2. The slope is going down 4 and right one which means the slope is -4. The y-intercept is b and the slope is m. If we plug these values into the equation y = mx + b we get:
y = -4x + 2
13. At x = 0, y = -3 so the y-intercept is -3. The slope is going up 1 and right 4 which means the slope is 1/4. The y-intercept is b and the slope is m. If we plug these values into the equation y = mx + b we get:
y = 1/4 x - 3
