To find the gradient of a line we first hv to find the formula
so Gradient=√X1-x2and √y1-y2
((-2,1) and (0,-5)) line 1
line 2(0,-1) and (1,0)
first we will work for line 1
X1 is -2
X2 is -0
Y1 is 1
Y2 is -1
so y=x-1
so we substitute the values
1--1=-2--0
so,
1+1=-2+0
2=-2
-0
So the equation 1 line 1 is not true
we will now go to equation 2 line 2
the equation is 3x+y=-5
we substitute the values
3(-2--0)+1--1=-5
3(-2)+-2=-5
-6+-2=-5
-8= -5
group like terms
Ur answer should look like this -3
So the answer is 3x+y=-5

Answer:
63x ft³
Step-by-step explanation:
To find the the volume of a rectangular prism you multiply all the dimensions (7 feet, x feet, and 9 feet in this case).
<u>7</u>×x×<u>9</u>=
<u>63×x</u>=
Volume= 63x ft³
Answer:
57.75 yards yard will she makes 14 panels.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
As per the statement: Katrina uses 4.125 yards of fabric for each curtain panel she makes.
To find the how many yard will she makes 14 panels.
By proportion definition,

By cross multiply we have;

Simplify:
x = 57.75 yards.
therefore, 57.75 yards yard will she makes 14 panels.
