I believe that the answer is about 11 square feet because when you divide 16 by 1.5, you get 10.666666667, and most likely they won't be accepting an answer like that. So, you round to the nearest square feet and you get 11.

What is the simultanous equation of 2x+y=–5 3x+2y=–8 equation Using the Substitution method​
Artyom0805 [142]

Answer: Equation form: x=-2,y=-1

Point form: (-2, -1)

Step-by-step explanation:

y=-\frac{3x}{2} -4

y=-2x-5

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

Solve by Substitution ---> 2x+y=-5 3x+2y=-8

Can u help me with my workk
eimsori [14]
You knew where to place the target based on the coordinates (-5,4). Starting from the origin (0,0), we know how many units to move to horizontally and vertically. We move the target 5 units to the left, because it is negative. We move the target 4 units up, because it is positive. (x,y)

could someone out there perhaps help me? i’m so lost even though it’s probably so simple. i’ll give you brainleist :)
Temka [501]

Answer:

y= -x+7, b= sqrt(2P/a), c=3P^2-b

Step-by-step explanation:

First, make a table regarding both of the equations. You will eventually find out that both lines intersect at the point (2, 5) after you find the points on the table. From there, subtract x from both sides in the equation x + y = 2. You will      get y = -x + 2. Since they said the line was parallel, find a line that has the slope of negative one. Since we know that this line intersects the point in which the first two lines intersect, we know that the y-intercept will be 7. The equation of the line would be y=-x+7.

Multiply both sides by 2. Then, divide both sides by a to get b^2=(2P/a). Take the square root to get the value of b, which is sqrt(2P/a).

Square both sides of the equation to get P^2=(b+c)/3. Cross multiply to get 3P^2=b+c. Subtract b from both sides to get c=3P^2-b.
