7x - y= -5. Standard form is when it is written with x and y on the same side, but x is not negative or a fraction. To find the slope and y intercept, you must change the first two equations to slope intercept. You get y=7x-5 for the first one and y=11/3x+5 for the seccond equation. Take the 5 as your y intercept and the 7 as your slope and you get y=7x+5. Now you need to change it into standard form. When all is said and done, your final answer should be 7x - y = -5.

Answer:
2√5
Step-by-step explanation:
The side ratios in a 30-60-90 triangle are ...
1 : √3 : 2
The longest side (x) is 2 times the length of the shortest side (√5), so ...
x = 2√5
x^2 +9x +25 + 44/x-2
