Answer:
x = -8/3
Step-by-step explanation:
So first let's simplify the expression. Grouping together like terms gives:
-3x + 7 = -1
Subtracting 7 from both sides gives
-3x = -8
Meaning x = -8/3
Answer:
c) 23
Step-by-step explanation:
The relationship between the amount of growth per 3 weeks is proportional.
If you made a table it would look similar to:
x | y | Rate of Change
1 | 3 | +0
2 | 5 | +2
4 | 8 | +3
6 | 12 | +4
8 | 17 | +5
10 | 23 | +6
Answer:
Step-by-step explanation:
I have to say that there is not enough givens to prove anything. If the statement given is all there is, then many things can be proven.
One
All you are given is that the diagonal is bisected. It does not mean that the other diagonal is bisected without more information. All you can prove is that DH = HF Definition of a midpoint.
Two
For the second one KO bisects JKM. What that means is that the two smaller angles are equal. Bisects means cuts in half.
JKO = KOM. KO cuts JKM in half The reason is definition of bisect.
Three
This one actually can prove some something.
AB = BC which equals AC
BC = CD which equals BD
Therefore AC = DB
This is the associative property of equality. So far it is the hardest one.
Four
DE perpendicular to EF
Join DF A triangle is formed by construction.
Triangle DEF if s a right triangle. Perpendiculars form right angles.
The answers to this question are y = -3x - 2 and 3x + y = -2
y + 5 = -3(x - 1)
y + 5 = -3x + 3
y = -3x - 2 --> a choice
3x + y = -2 -- > a choice
