Let's find the slope (m) :
[tex] \dfrac{y2 - y1}{x2 - x1} [/tex][tex] \dfrac{16 - 11}{9 - 6} [/tex][tex] \dfrac{5}{3} [/tex]slope of given line is 5/3
now, let's plug the value of coordinates of a point lying on the line ( for example : (6 , 11) and slope (m) to find the y - intercept (c) :
[tex]y = mx + c[/tex][tex]11 = \bigg(\dfrac{5}{ 3} \times 6 \bigg) + c[/tex][tex]11 = (5 \times 2) + c[/tex][tex]11 = 10 + c[/tex][tex]c = 11 - 10[/tex][tex]c = 1[/tex]value of y - intercept (c) = 1, so our equation will be :
[tex]y = mx + c[/tex][tex]y = \dfrac{5}{3}x + 1[/tex]Find the area of the figure. (Sides meet at right angles.)

The perimeter of a square is 4/5 what is its area
Answer:
1/25
Step-by-step explanation:
square has 4 sides, if you add them all up you get 4/5.
1/5+1/5+1/5+1/5=4/5
so each side is 1/5
Area=length * width
A=1/5*1/5=1/25

Have you ever been at sea in a dense fog, when it seemed
as if a tangible white darkness shut you in, and the great
ship, tense and anxious, groped her way toward the shore
with plummet and sounding-line, and you waited with
beating heart for something to happen? I was like that ship
before my education began, only I was without compass or
sounding-line, and had no way of knowing how near the
harbour was. "Light! give me light!" was the wordless cry of
my soul, and the light of love shone on me in that very
hour.

According to the synthetic division below, which of the following statements are true? Check all that apply.
-6)2 9 -12 2 -3 11
A. When x = -6,2x2 + 9x-7 = 11.
B. When x = 6,2x2 + 9x-7 = 11.
C. (x-6) is a factor of 2x + 9x- 7.
D. When (2x + 9x-7) is divided by (x - 6), the remainder is 11.
E. When (2x2 + 9x - 7) is divided by (x + 6), the remainder is 11. F. (x+6) is a factor of 2x2 + 9x-7.
The last number on a synthetic division represents the remainder of the division.
The true statements are:
(a). When x = -6, 2x^2 + 9x - 7 = 11. (e). When (2x2 + 9x - 7) is divided by (x + 6), the remainder is 11.From the question, we have the dividend to b 2x^2 + 9x - 7, the last number to be 11, and the zero of the divisor to be -6.
This means that:
[tex]x = -6[/tex] --- the divisor
Set to 0
[tex]x+6 = 0[/tex]
So, when the dividend 2x^2 + 9x - 7 is divided by divisor x + 6, the remainder is 11.
This also means that, when -6 is substituted for x in the dividend, the remainder is 11
Hence, the true statements are (a) and (e)

so since nine is the whole number part of "9 1/2" you can easily subtract 4 from if (bc it's another whole number) but the confusing part of this problem is the "+(-4)" the parentheses are just so you don't mix up the + and -, but regardless, when you add a negative number it's the same as subtracting.
