Lol, that took a while, hope it helps!
Given :
Two equations :
-8x + 3y = -17 ....1)
3x - y = 7 ....2)
To Find :
The solution of the system.
Solution :
Multiplying equation 2) by 3 and adding with equation 1), we get :
(-8x + 3y) + 3(3x - y) = -17 + 21
x = 4
Putting above value of x equation 2) we get :
12 - y = 7
y = 5
Therefore, solution of system is ( 4,5 ).
Perpendicular lines have gradients that multiply to give -1
So, the gradient of the line we need is -1/0.2 = -5
If we have the gradient and a point in the line, we can work out the equation using the formula:
y - y1 = m(x - x1)
where m = gradient, y1 = y-coordinate and x1 = x-coordinate of the same point
So, we substitute in our values, and we get:
y - -8 = -5(x - -7)
y+8 = -5x-35
y = -5x-43
Hope I helped! xx
It would be 8.525
The 8 is 8
Divide 21 by 40
Answer:
D.) x = 7
Step-by-step explanation:
4x - 9x + 3 = -32
The first thing we do is combine like terms which means to add or subtract or multiply or divide any numbers that are known. Here in this equation we have 4x and - 9x
4x - 9x + 3 = -32
- 5x + 3 = - 32
Now what we do is subtract the common numeral from the side where the x value is.
- 5x + 3 = - 32
- 3. - 3
- 5x = - 35
Lastly, we divide here we take the value next to x and divide both numbers, here we will divide by - 5.
- 5x = - 35
- 5x / - 5 = x
- 35 / - 5 = 7
Now we take are two solutions and create are final solution.
x = 7
