prohojiy [21]

Answer:

x = - 20

Step-by-step explanation:

$\frac{x}{4} + 8 = 3 \\ \\ \frac{x}{4} = 3 - 8 \\ \\ \frac{x}{4} = - 5 \\ \\ x = - 5 \times 4 \\ \\ \huge \red { \boxed{ x = - 20}}$

Which classification describes the following syastem of equations? x=5 y=6 -x - y +z = 0

Papessa [141]

Answer:

Is a consistent independent system

Step-by-step explanation:

we know that

If a system has at least one solution, it is said to be consistent .

If a consistent system has exactly one solution, it is independent .

If a consistent system has an infinite number of solutions, it is dependent

If a system not have solution, it is said to be inconsistent

we have

$x=5$ ----> equation A

$y=6$ ----> equation B

$-x-y+z=0$ ----> equation C

substitute equation A and equation B in equation C

$-5-6+z=0$

Solve for z

$z=11$

The solution is the point (5,6,11)

The system has only one solution

therefore

Is a consistent independent system

A scatter plot containing the point (5,9) has the regression equation y = -x-3 (see photo)

Tatiana [17]

The residual is the difference between the plotted point and the line of best fit.

We first need to know the point at x=5 for the line of best fit.
y1 = -(5) - 3 = -8

Now we need to find the difference between the line of best fit and the plotted point.
residual = 9 -(-8) = 9 + 8 = 17 or C
