16.) label the picture. the sign in the middle means they are congruent(equal or same)
7.) if it's asking for the midpoints then that's how you find it.
<span> x – 3y = 9 ------------ (1)
1/5x - 2y = -1---------- (2)
(1):
x - 3y = 9
x = 9 + 3y ----------- (1a)
(2):
</span>1/5x - 2y = -1
x - 10y = -5 --------- (2a)
Sub (1a) into (2a):
9 + 3y - 10y = -5
9 - 7y = -5
-7y = -5 - 9
-7y = -14
7y = 14
y = 2 ---------- Sub into (1a)
x = 9 + 3y
x = 9 + 3(2)
x = 9 + 6
x = 15
Ans: x = 15, y = 2
Answer:
There are three fourths in 3 fourths
Step-by-step explanation:
Fourth represents
Therefore, 3 fourths will be given as:
Therefore,
No. of fourths in 3 fourths =
No. of fourths in 3 fourths =
This is a quadratic whose graph will be the shape of a U.
when x = 0 y = 0 so it will pass through the origin ( the point (0,0).
Plot a few more points - say when x = 1 and x = -1 . Also when x = 3 and x = 3
For example when x = 1 y will be -1 - 1^2 = 0 giving the point (1, 0)
Note the minimum point will be (0.5, -0.25)
