Answer:
the answer is 2.2+(-2.5)
Step-by-step explanation:
Do 2.2 + (-2.5) and when you add a negative number it's like subtraction because a negative number is under 0 and so your adding a number under 0 so you go down. So the answer is 2.2+(-2.5)
(-3/4, -7/2)
y= −2x − 5
y= 2x − 2
2y = -7
y = -7/2
-7/2 = 2x - 2
2x = -3/2
x = -3/4
(x,y) = (-3/4, -7/2)
divide 90 and 30 to see what you got
A= 153.86
A=49
You again....
