Answer (<u>assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line by using the slope formula,
. Substitute the x and y values of the given points into the formula and solve:
So, the slope is -12.
2) Now, use the point-slope formula
to write the equation of the line in point-slope form. Substitute real values for
,
and
.
Since
represents the slope, substitute -12 in its place. Since
and
represent the x and y values of a point the line intersects, choose one of the given points (any one is fine, it will equal the same thing at the end) and substitute its x and y values into the formula as well. (I chose (2,4), as seen below.) Finally, isolate y to put the equation in slope-intercept form to find the following answer:
2k + 9 = 7 - 3k
2k + 9 - 7 = -3k
2k + 2 = -3k
2 = -3k - 2k
2 = -5k
-2/5 = k
k = -2/5
hope that helps, God bless!
Work is shown (^_^)
Did #9-10 also
3) 3p -2 = -29 Isolate 3
3p= -29+2
3p= -27 Divide by 3
p = -9
4) 1- r = -5 Isolate r
-r= -5-1
-r= -6 Multiply by -1
r= 6
5) k-10/2 = -7 Multiply by 2
k-10= 2(-7)
k-10= -14
k=-14+10
k=-4

Answer:
Step-by-step explanation:
Janet can make:
4/5 of a necklace in 20min
2(4/5)=8/5 ............in 40 min
3(4/5)=12/5 ............in 60 min( one hour)
12/5=2 2/5 necklaces in one hour
or 2.4n in one hour
Answer:
Length is 3 meters and the Width is 5 meters
Step-by-step explanation:
L*W=15
L=2W-7
(2W-7)W=15

(2W+3)(W-5)=0, don't use (2W+3)=0, because it gives you a negative dimension.
W=5, L=3
