You first subtract 5x from both sides and end up with -3y=21-5x. In order to isolate the variable you need to divide -3 from both sides. Your equation would then be y= -7+ 5/3x. I hope this helps love! :)
If you know the coordinates of two points
of two points, the slope of the line passing through them is given by
So, if we choose in this example
The slope is
Y/5.....the quotient of y and 5
14.1 - w....the difference of 14.1 and w
9n + 1....the product of 9 and a number (n), increased by 1
(z/8) - 9.....9 less then the quotient of z and 8
15 - (1.5/d) ....15 decreased by the quotient of 1.5 and a number (d)
Answer:
x f(x) + 1
-4 6
-2 8
2 2
4 -1
Step-by-step explanation:
5 + 1 = 6
7 + 1 = 8
1 + 1 = 2
-2 + 1 = -1
H(d)=height from water
when he reaches the water, his height from water=0
so set the equation equal to zero and solve
0=-d^2+2d+24
multiply both sides by -1 for ease
0=d^2-2d-24
now find what 2 factors of -24 add up to -2
answer is -6 and 4
0=(d-6)(d+4)
set each to zero
d-6=0
d=6
d+4=0
d=-4
you cannot have negative distance because that means he hasn't jumped yet so get rid of this number
d=6
answer is 6 meters
