Answer:
y = x - 3
Step-by-step explanation:
First find the slope/rate of change of the table. Find the difference between the intervals of the x and y values of the table. Each time the x value decreases by 2 the y value decreases by 4. To find the rate of change divide the -4 by -2 to get 2 as the slope.
Set up an equation using values from the table to figure out the y intercept or b value.
-6=-4(2)+b
-6=-8+b. Add 8 from both sides
both sides to get b
2=b
The y intercept is (0,2)
The equation of the line is Y=2x+2
Plug in 0 for y into the lines equation to get the x intercept
0=2x+2
-2=2x. Divide by 2 to isolate x
-1=x
The x intercept is (-1,0)
Step-by-step explanation:
y= x+1 -> (y1)
x²-y = 5 => y = x²-5 -> (y2)
(y2) = (y1) =>
x²-5 = x+1
x²-x-6 = 0
(x-3) (x+2)=0
x1=3 or x2 = -2
y1= 3+1 = 4
y2=-2+1 = -1
the intersects are : (3, 4) and (-2, -1)
so, the point A = (-2, -1) => lies below the x-axis.
and the point B = (3, 4)
the point P :
X = -2 + (4/5 × [3-(-2) ])
= -2 + (4/5 ×5)
= -2 +4 = 2
Y = -1 + (4/5 × [4-(-1) ])
= -1 +(4/5 ×5)
= -1 +4 = 3
so, the coordinates P = (2, 3)

Answer:
5
Step-by-step explanation:
First find the number that have their own cell phone
1/4 * 40 = 10
There are 10 students with their own cell phone
1/2 of the 10 can use social media
1/2 * 10 =5
5 have their own cell phone and can use social media
