Answer:
the desired equation is
y = (1/2)x - 21/2
Step-by-step explanation:
Looks as tho' you may have typed in an extra 'y' here. I will proceed under the assumption that you meant y = (1/2)x - 4. This line has a slope of 1/2.
Any line parallel to it also has a slope of m = 1/2.
Start by replacing y, x, m and b in y = mx + b with the knowns:
y = mx + b becomes -6 = (1/2)(9) + b.
Clear this of fractions by multiplying all 3 terms by 2:
-12 = 9 + 2b, or:
-21 = 2b. Dividing both sides by 2 results in b = -21/2.
Thus, the desired equation is
y = (1/2)x - 21/2
Answer:
h=-16t^2+ 30t+4.
Step-by-step explanation:
For the table you just plug in the <em>t</em> (time) into the equation. So for the first one we have 0 seconds. So you plug in the 0 where it says <em>t</em>. So the equation becomes h=-16*0^2+30*0+4. Which gives us 4 <em>h</em>(height). Then you keep pluging in the time into the equation.
Time <em>t </em>in seconds 0 .5 1 1.5 2
Height <em>h </em>in feet 4 15 18 13 0
Answer:
y=-2x+5
Slope: -2
y int. 5
Step-by-step explanation:
Convert to slope intercept form
2y-10=-4x
Add 10 to both sides
2y-10+10=-4x+10
Simplify
Divide both sides by 2

Simplify
y=-2x+5
Slope: -2
y intercept: 5
Answer:
30
Step-by-step explanation:
The sum of all the angles in a triangle is always, always, 180 degrees.
Just add the angles, then solve for x.
(2x - 10) + (x + 30) + 70 = 180
3x + 20 + 70 = 180
3x + 90 = 180
3x = 90
x = 30
