Answer:
x= -2; x ≥ 2
Step-by-step explanation:
1. -3x+2=8
<u>Subtract +2 </u>on both sides
-3x+2<u>-2</u>=8<u>-2</u>
<u></u>
-3x=6 <u>Divide by -3 </u>on both sides
-<u>3x</u>/-3=6/<u>-3</u>
<u></u>
<u>x= -2 </u>
<u>-</u><u>2 is the answer for both the equation and inequality.</u>
<u />
<u>sorry i was lazy to do the inequality one, but it should be the same answer.</u>
<u />
<u>also ignore the fact that theres a line, i could not find the sign without one, o im sorry.</u>

A is the right one:
a. 3:4=9:12
3×3:4×3=9:12
¹¹/48 of the full cup
Step-by-step explanation:
We add the two fraction first to determine the total ratio
¹/4 + ²/3 = ¹¹/12
She uses ¼ cup grape juice for ¹¹/12 cup full of diluted grape juice
Therefore;
¼ : ¹¹/12
How How much grape juice does Sarah use for each full cup of water, i.e ¹²/12
? (x) : ¹²/12
We cross multiply the ratios;
¹²/12 * ¼ = ¹¹/12 * x
³/12 = ¹¹/12 x
³/12 * ¹²/11 = x
¹¹/48 = x
Answer:
a) The center coordinates O is (0,0)
b) The radius C = 15
Step-by-step explanation:
The given equation of the circle is : 
Now, general form of the equation of the circle is:
where (h,k) are the center co -ordinates and r is the radius of the circle.
Comparing the general equation with the given equation, we get
So, here the center coordinates (h,k) = (0,0)
And the radius of the given circle is r = 15
