You substitute x in for y and would get x=-x-4 then you add x to both sides to cancel X out and leave -4 alone on one side. So you would have 2x=-4 so divide by two on each side and you get x=-2

So the answer would be x=-2

Figure on the left is a trapezoid. All angles in the figure on the right are right angles. All dimensions are in centimeters.
IRISSAK [1]
The area of the trapezoid is 221. You get that by multiplying 13 and 17. The area of the figure on the right is 119. You get that by subtracting 5 from fourteen to give you 9. Then you multiply 9*11=99. After you have that done you need to figure out the little square, which is 5*4=20. Add 99+20=119.

Hope this helps

The first term of a geometric sequence is 6, and the ratio (multiplier) is 0.5. What is the sum of the first 8 terms, rounded to
IRISSAK [1]
The sum of the first n terms of a geometric sequence is given by:

S_{n}=\frac{a_{1}(1-r^{n})}{1-2}

Using the known values:
S_{8}=\frac{6(1-0.5^{8})}{1-0.5}
S_{8}=\frac{6(1-0.00390625)}{0.5}
S_{8}=\frac{6(0.99609375)}{0.5}
S_{8}=\frac{5.9765625}{0.5}
S_{8}=11.953125
