Answer:

y=11,x=8

Step-by-step explanation:

2x+y=1

4x+2y=-1

substitution method

y=2x-1

4x+2(2x-1)=1

4x+4x-2=1

8x-2=1

8x=1

x=8

equation 2

4x+2y=-1

4(8)+3y=-1

32+3y=-1

-33=3y

y=11

Explain how you can determine the initial value of a linear relationship, the y- intercept, when given two points.
Paladinen [302]
There is a formula to find the slope (m)

(y2 - y1) / (x2 - x1)

So we now have y = mx + b where m is the value you just calculated

The y intercept (b) = y - mx

Plug in the x,y values for one of your points into this formula

Can anyone please work out question 10 in the picture and clearly explain it? Would appreciate it

9945/ 39= 255
If you were to try to divide 99 by thirty five it would not be a whole. You would be able to multiply 39 by 2 to get 78. 99 subtracted by 78 = 21 you would then carry down the 4. to equal 214 you would then figure out 39 multiplied by 5 is the highest number to figure a 195 you would have 19 left over. Carry down your 5 and would have 195. You would have 195 again and then multiply 39 by 5 and it would equal out to 195. Your answer would then be 255.
