you have to put it in Point Slope Form.
ABOUT POINT SLOPE FORM:
- y- Y1 = m(x - X1)
- Y1 & X1 is a point on the line
- The form allows you to identify the slope & the point on the line
ABOUT PROBLEM:
- Since the slope is -3, it represents m in the Point Slope Form
- 4 represents X1
- 8 represents Y1
y - Y1 = m(x - X1)
y - 8 = -3(x - 4) --- IN Point Slope Form
If you want to put it in Slope Intercept Form, you can solve it:
y - 8 = -3(x - 4)
y - 8 = -3x + 12
+ 8 + 8
y = -3x + 20 --- IN Slope Intercept Form
- Remember, a negative times a negative becomes a positive
Answer:
f(2)=16
Step-by-step explanation:
f(x) = 3x^2 - x +6 If you notice what the 2 is replacing in f(2) then replace it in the equation:
f(2) = 3(2)^2 -2 +6 Use the order of operations to solve (PEMDAS)
f(2) = 3(4) - 2 + 6
f(2) = 12 - 2 + 6
f(2) = 12 + 4
f(2) = 16
0.25e − 14 = 26 Then you add 14 from both sides
0.25e=40 Then you divide both sides by 0.25
e=160
Then to check you work you do this:
0.25(160)-14=26
40-14=26
26=26 Correct!!!!
Answer:
y = -3/2x + 5/2
Step-by-step explanation:
slope intercept form is y = mx + b
so we have to solve the equation for y
2y = 5 - 3x
y = 5/2 -3/2x
or
y = -3/2x + 5/2
