Mathematics

Ainat [17]3 years ago
3 0

we have

6x+7y=4x+4y

we know that

the solution is ----> (x,-4)

substitute the value of y=-4 in the equation

6x+7*(-4)=4x+4*(-4)

6x-28=4x-16

Combine like terms

6x-4x=28-16

2x=12

x=12/2

x=6

therefore

<u>the answer is</u>

the missing value is x=6

Given the graph below write the equation of the line.
Scrat [10]

Answer:

y = 2x+8

Step-by-Step Explanation:

The equation should be in the form of y=mx+b

So you already know it's not A. Also you already know it's not D because the line goes at an angle, if "m"(slope) was 0 then the line would be straight horizontal or straight vertical. So that leaves B and C. And finally you know it's not B because the line is going in the positive direction not negative, so the slope has to be positive, also "b" in the equation is the y-intercept, and that's where the line intersects with the y-axis, and you can see that the line intersects at 8 on the graph. Therefore, the answer is C, y=2x+8

Hope this helps!! :)
