Answer:

The solution of the given system is (x,y) = (1,4)

Step-by-step explanation:

Here, the given system of equation is:

x = -3 + y

26 x - 5 y = 6

Now, substitute x = -3 + y in the second equation , we get

26 x - 5 y = 6 ⇒ 26 (-3 + y) - 5 y = 6

or, 26(-3) + 26(y) - 5y = 6

⇒ - 78 + 26 y - 5y = 6

⇒ 21 y = 84

⇒ y = 84 / 21 = 4 or , y = 4

So x = -3 + y = -3 + 4 = 1

Hence, the solution of the given system is (x,y) = (1,4)

Answer:

y=2x+6

Step-by-step explanation:

slope intercept formula → y=mx+b

$\frac{6-2}{0-(-2)} =\frac{4}{2} =2\\$

so 2 is your slope and the point (0,6) crosses the y-intercept at 6 since x = 0

plugin 2 for m (or the slope) and 6 for b (y-intercept)

your answer → y=2x+6

(9x-9)(9×+9), your finding the difference between two squares. im have some trouble in how to solve it.

sergejj [24]

Answer: Your answer is 0 (F.O.I.L) first. outer. inner. last. Or you could use what my teacher calls the magic box

Step-by-step explanation:

So for the boxes you multiply for example the top left box you multiply the 9 above it and the 9 to the left or like the top right box you multiply the -9 above it and the 9 on the outside of the box to the left

How do you solve y=3/4x+3 on a graph?

kow [346]

So by looking at this equation you should look to see it's key features which will help you graph the equation. the first key feature is the slope, the slope lets you know the angle at which the line will be, the slope in an equation will always be the number multiplied by x ( in this case it'd be 3/4). The second feature is the y intercept, the y intercept is where the equations line crosses the y axis, the y intercept in a graph will always be what is added or subtracted after the x (in this case it'd be 3).
To simplify what I said look at the following:
Slope: 3/4
Y intercept: 3
Hope this helps!

What value of x would make the figure a parallelogram (show your math please)

Verdich [7]

Answer:

Step-by-step explanation:

Diagonals of a parallelogram bisects each other.

Therefore,

4x = 8

x = 8/4

x = 2

5x = 3x + 4

5x - 3x = 4

2x = 4

x = 4/2

x = 2
