Answer: Yes
Step-by-step explanation:
the exact answer is 42 .
Answer:
length: 6 inches
width: 7 inches
Step-by-step explanation:
Let n represent the number. Then the length is (n+2) and the width is (2n-1). The product of these dimensions is the area:
42 = (n+2)(2n -1) = 2n^2 +3n -2
2n^2 +3n -44 = 0 . . . . subtract 42
(n -4)(2n +11) = 0 . . . . . factor
n = 4 . . . . . . . . we aren't interested in the negative solution
Length = 4+2 = 6 . . . inches
Width = 2·4 -1 = 7 . . . inches
Answer:
y = [-½]x + [-5]
Step-by-step explanation:
Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.
m = slope = ∆y/∆x
Using two pairs of values from the table, (-2, -4) and (0, -5),
Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2
m = -½
b = y-intercept = the value of y when x is 0 = -5
b = -5
✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b
Thus:
y = [-½]x + [-5]
First we have to find the slopes and the points are (-3,4) ,(0,-2) .
Slope of parallel lines are equal. Therefore the slope of the required line is -2 too .
Using slope intercept form which is
y=m x+b
We have point (-5,2) and slope, m =-2
Substituting the values of x,y and m
2 = -2(-5)+b
2 = 10 + b
Subtracting 10
-8 = b
So we have slope = -2 and y intercept, b=-8. THerefore required equation of line is
y=-2x-8.
