Answer:
( -4, -3 )
Step-by-step explanation:
Let's solve by elimination. Reason being there are no variables without coefficients.
−5y+3x=3 Multiply equation by 3. Each term.
−8y+9x=−12
-15y + 9x = 9 Subtract the to equations
-8y + 9x = -12
___________
-7y = 21
y = -3
Substitute y into original equation
-5(-3) + 3x = 3
15 + 3x = 3 Subtract 15 both sides
3x = -12 Divide by 3, both sides
x = -4
Plot a point at the y-intercept of -2 or y = -2
--------------------------------------------------------------------
From there make a straight horizontal line
---------------------------------------------------------------
Then Shade the upper-half of that line one color This shaded part stands for
Y > -2
-----------------------------------------------------------------------
Shade the lower half a different color, this stands for y ≤ 6
-------------------------------------------------------------------------
That should be it!
Hi,
75/150 is 1/2 which turns into 0.5 as a decimal.
To answer this question you would need to know the formula for the area of a circle,
. You would start by squaring 400, getting 160,000. You would then multiply 160,000 by 3.14, getting 502,400 meters squared as your answer.
