Answer:
213
Step-by-step explanation:
convert percent to decimal 48%=0.48
144x0.48= 69.12
estimate 69.12 we got 69
144+69=213
Answer: X > 3
Step-by-step explanation:
You want to subtract 14 on both sides and you will get -3x < -9. Then you divide -3 on both sides -3x/3 > -9/-3 and you should end up with x < 3. Since you divided by the negative number you switch the sign from ">" to "<"
Hope this helps and sorry if it did not.
Such an equation would be y + 8x = - 25 (standard form) OR y = -8x - 25 (y-intercept form)
Deriving The Answer:
By using the point-slope form of the equation of a line, by knowing the gradient of that line and a point on that line, the equation of this line can be derived.
Now, the point-slope form exists as y - y₁ = m ( x - x₁)
since slope = -8 and the point on the line = (-4 , 7)
Then m = - 8
x₁ = - 4
y₁ = 7
⇒ y - 7 = -8 ( x - (-4))
⇒ y - 7 = -8x - 32
⇒ y + 8x = - 25
Answer:
[2 5 0]
[-7 -11/2 12]
Step-by-step explanation:
We want to perform elementary row operation represented by R2 - ½R1 on matrix A in the figure attached.
Now, matrix A is given as;
[2 5 0]
[-6 -3 12]
Now, R1 is row 1 = [2 5 0]
R2 is row 2 = [-6 -3 12]
Thus, R2 - ½R1 = [-6 -3 12] - ½[2 5 0]
This gives;
[-6 -3 12] - [1 5/2 0] = [-7 -11/2 12]
Now,[-7 -11/2 12] will be the new row 2 since it's just an elementary row operation we did on the Matrix A.
Thus, the new matrix is now;
[2 5 0]
[-7 -11/2 12]
Answer:
Look below
Step-by-step explanation:
We can start by writing an equation.
Let x be the width. The length would be x+4.
The equation would be:
96=2(x+x+4)
Divide both sides by 2
48=x+x+4
Add like terms
48=2x+4
Subtract 4 from both sides
44=2x
Divide both sides by 2
x=22
x+4=26
The width is 22 inches and the length is 26 inches.
