The student had a 40% error estimate
Answer:
The numbers in the second row of each collumn is increasing by 4 every time the numbers in the first row increase by 1.
Answer:
y=-8/5x+4
Step-by-step explanation:
The slope of perpendicular lines is the opposite reciprocal of the original equation.
To get the opposite reciprocal, flip the fraction and use the opposite sign.
Here, the slope is -8/5 because that is the opposite of 5/8.
To get the equation of the line, use point-slope and then distribute to get the equation in y=mx+b format.
Point slope: y-y1=m(x-x1). Use the coordinate (5,-4) in the equation.
y+4=-8/5(x-5)
Multiply (x-5) by -8/5 and simplify.
y+4=-8/5x+8
y=-8/5x+4
Subtract 40 from both sides
-vp+40-40<95-40
Simplify
-vp<55
Multiply both sides by -1 (reverse the inequality)
(-vp) (-1) > 55 (-1)
Simplify
vp> -55
Divide both sides by v
vp ÷ v > -55 <span>÷ v
</span>
Simplify
p> -55 <span>÷ v </span>
=> 8+x = 15 => x = 15-8=7
