Answer:
The numbers are 23 and 7
Step-by-step explanation:
1. Set up the equations
Let x = the greater number
and y = the smaller number. Then
(1) x - y = 16
4y = 4 times the smaller number and
4y - 5 = 5 less than 4 times the smaller number. Then
(2) x = 4y - 5
You have a system of two equations:
2. Solve the equations
The larger number is 23; the smaller number is 7.
3. Check
OK.
Hello :
<span>2y + 3 = 0
y = -3/2
y +3/2 = 0(x-0) satandard slope form when : m = 0
the line is parallal a x -axis</span>
The line passes by the points (2,-3) , (-2,5)
so the equation of a line passes by 2 points is (y-y1)/(x-x1) = slope
slope = (y2-y1)/ (x2-x1)
= (5-(-3)) / ( -2-2)
= 8/-4
= -2
then subs. in the 1st equation of the line
(y-(-3)) / ( x-2) =-2
so,, (y+3) = -2(x -2)
so the answer is the 1st one
to make sure ur equation is right subs in the equation by the point (0,1)
if R.H.S = L.H.S
then ur equation is right
Answer:
A=74.24 f^2
Step-by-step explanation:
Triangle:
1/2 x 6x 8
=24
Half a circle
3.14x 4^2 ÷ 2
=25.12
Then plus it together
24+25.12
=49.12 ft
-1 and -6 have the same sum as -2 and -5, which is -7
