Answer:
y +1 = -3(x -3)
Step-by-step explanation:
The given point is (3, -1), and the given slope is -3. The form suggests you want the point-slope form of the equation for the line:
y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)
Using the given values, the equation is ...
y -(-1) = -3(x -3)
y +1 = -3(x -3)
Answer:
1st and 2nd Equation; what = 2.25, 3rd Equation; what = 4.44444
Step-by-step explanation:
40/4 / 9/4 = 40/9 = 4.44444
I believe x is 43.
3x+17+x-9=180 It is 180 because a straight line is 180 degrees
4x+8=180
-8 -8 subtraction property of equality
---------------
4/4x=172/4 division property of equality
x=43 solution
Answer:
The wide of the walkway is 5ft.
Step-by-step explanation:
In first place you have a rectangular garden of 30ft by 40 ft as shown in Figure 1 (Added file).
So, the area of this rectangle is:
Area=1200ft
Now, the new garden has a walkway of uniform width around it, and the area of the new rectangle is one-half the area of the old garden
In order to be a walkway of uniform width it's necessary to substract of each side the same amount, for this case will be 5 ft, as shown in the Figure 2. Now the new rectangule is 20ft by 30ft.
Which is exactly one-half the area of the old garden.
This means the width of the walkway is 5ft.
Based on the information given the percent of the total cost of the bike has Wu saved is 30%.
Using this formula
Total cost percentage=Amount saved/Cost×100
Where:
Amount saved=$75
Cost =$250
Let plug in the formula
Total cost percentage=$75/$250×100
Total cost percentage=30%
Inconclusion the percent of the total cost of the bike has Wu saved is 30%.
