This is how you solve it, and here is the answer!
Y=-2x+b
1=-2*(1)+b
1=-2+b
B=1+2=3
Y=-2x+3
2x+y-3=0
Answer:
Step-by-step explanation:
Let
x -----> the number of hours that the painter works
we know that
The inequality that represented this situation is equal to
solve for x
Subtract 60 both sides
Divide by 15 both sides
The maximum number of hours is 2
Answer:
It takes George 1 hour longer to mow the lawn than it takes Henry. Working
together, using two mowers, they can mow the lawn in 1 hour and 12 minutes.
How long would it take Henry to mow the lawn by himself?
Step-by-step explanation:hope this not wrong
Let's organize.
The question says to <u>identify</u> an <u>equation in point-intercept form</u> for the <u>line</u> that's <u>parallel</u> to y = -3x + 7 that <u>passes through</u><u /> (2, -4).
If you need to find an equation in point-intercept form that passes through a point, you will substitute the coordinate in this formula:
-> y - yo = m (x - xo)
Where:
(2, -4) -> xo = 2 ; yo = -4
m = Slope
You don't have the slope, but you have the information that the line is <u>parallel</u> to <u />y = -3x + 7. Then you need to know that to a line be <u>parallel to another</u> the Slopes of each other must be equal, mr = ms.
Let's find the slope of the equation given, it is in a slope-intercept form, so:
y = mx + b
R: y = -3x + 7 // I will call this one R line, and the other S.
mr = -3
If the mr = ms, and mr = -3, then the ms = -3 too.
S: y - yo = ms (x - xo) // (2, -4) & ms = -3
-> y - (-4) = -3 (x - 2)
-> S: y + 4 = -3 (x - 2) -> This is the point-slope form.
-> y = -3x + 6 - 4
-> S: y = -3x - 2 -> This is the slope-intercept form.
I didn't understand what is the point-intercept form that the question requests, but by logic, i think that's the point-slope form.
Answer: The equation in point-intercept form is: y + 4 = -3 (x - 2).
