Slope 0, passes through (0, –10)

1 answer:

5 0

Answer:
y=-10

Explanation:
The answer choices are all in slope-intercept form, which is this equation:

y=mx+b

Here’s what the variables mean:

Y=the y axis
M=the slope
X=the x axis
B=the point on the line that intercepts the y axis (the y-intercept)

We know the slope is 0, so 0 would be the m variable.

y=0x+b

We also know that the line passes through (0,-10), which means the y-intercept is -10.

y=0x+(-10)

0 multiplied by anything equals 0 and a negative and positive makes a negative, so we can rewrite the equation to be this:

y=-10

I hope this helps! Please comment if you have any questions.

The x coordinate of the solution to the system of equations y=x+4 and 3y=-2x+2

Vera_Pavlovna [14]

<h2>Hello!</h2>

The answer is:

The x-coordinate of the solution to the system of equations is:

$x=-2$

We can solve the problem writing both equations as a system of equations.

So, we are given the equations:

$\left \{ {{y=x+4} \atop {3y=-2x+2}} \right.$

Then, solving by reduction we have:

Multiplying the first equation by 2 in order to reduce the variable "x", we have:

$\left \{ {{2y=2x+2*4} \atop {3y=-2x+2}} \right.$

$5y=2x-2x+8+2\\\\5y=8+2\\\\y=\frac{10}{5}=2$

Now, substituting "y" into the first equation, to isolate "x" we have:

$y=x+4\\\\2=x+4\\\\x=2-4=-2$

Hence we have that the x-coordinate of the solution to the system of equations is

$x=-2$

Have a nice day!

I don't understand???? I'll give the brainliest!!!!!

olasank [31]

Answer:

Option A is the correct option.

Step-by-step explanation:

${a}^{2} + {b}^{2} - 2ab \: \cos \: c \: = {c}^{2} \\ a = 4 \\ b = 5 \\ c = 2 \\ \\ 2ab \: cos \: c = {a}^{2} + {b}^{2} - {c}^{2} \\ \: \: \: \: \: \: \: \: = {(4)}^{2} + {(5)}^{2} - {(2)}^{2} \\ \: \: \: \: \: \: \: \: = 16 + 25 - 4 \\ \: \: \: \: \: \: = 41 - 4 \\ \: \: \: \: \: \: = 37$

Hope this helps...

Good luck on your assignment...

What is the result of subtracting the second equation from the first? \begin{aligned} x-3y &= 6 \\\\ -8x-y &= 6 \end{ali

Mila [183]

Answer:

Therefore the required result is 9x-2y =0.

Step-by-step explanation:

Given equation are

x-3y =6.....(1)

-8x-y=6 .....(2)

Subtracting equation (2) from (1)

x - 3y = 6

-8x - y= 6

+ + - [ The sign of equation (2) will be change in case of

_________ subtraction and in case of plus the signs remains same ]

(x+8x)-3y+y=6-6 [ adding the like terms]

⇒9x-2y =0

Therefore the required result is 9x-2y =0.

Select all of the equations that are not functions.

Kryger [21]

Answer:

Step-by-step explanation:

x² + y² = 3 creates a circle and circles are not functions because one x-value relates to two y-values instead of one
