Y = -x + 10 and y = 2x + 4

Mathematics
1 answer:
igor_vitrenko [27]3 years ago
8 0

Answer:

X=2, y=8

Step-by-step explanation:

Y=-x+10 equation 1

y=2x+4 equation 2

-x+10=2x+4. Substitute y of first equation into 2nd equation

-x-2x+10=4

-3x=4-10

-3x=-6

x=2

solve for y by inserting x value into either equation

y=-x+10

y=-2+10

y=8

check answer

y=2x+4

8=2(2)+4

8=4+4

8=8

Solve the system of equations.<br><br>- 9x + 4y = 6<br><br>9x + 5y = -33​
liubo4ka [24]

Let us solve this system of equations by using the elimination method. Adding the 2 equations, we get

9x + 5y - 9x + 4y = -33 + 6

9y = -27

y = -3

Substituting this value of y in the first equation, we get

-9x + 4(-3) = 6

-9x - 12 = 6

9x + 12 = -6

9x = -18

x = -2

Therefore, x = -2, and y = -3. Hope this helps! If you have any questions, feel free to ask.

Write the equation in slope-intercept form of the line that contains the points (4, -7) and (0, 5).
LenaWriter [7]
The slope intercept form is y=mx+b
The slope formula is m=(y2-y1)/(x2-x1)
So; 5-(-7) / 0-4= -3
Then you use one of the points to find b; I’ll use 0 and 5 (the first number is x and the second number is y)
5=(-3)(0)+b
5=0+b
5=b
Finally you plug in your two values
Y= -3x+5

Hope this helps :)
