Answer:
D..... 3 lines of Symmetry
Answer:
4 - 1x
Step-by-step explanation:
This could also just be written as 4-x because one times anything is itself, so the one is kinda unnecessary but yup
Answer:
4.4 ≤ x
Step-by-step explanation:
2/5 ≤ x -4
solve using inverse operations:
2/5 ≤ x - 4
0.4 ≤ x - 4
+4 +4
4.4 ≤ x
we know that
m∠ZWY=m∠WXY --------> given problem
so
In the right triangle ZWY
In the right triangle XWY
<u>Find the value of b</u>
<u>Applying the Pythagorean Theorem</u>
In the right triangle XWY
therefore
<u>the answer is the option</u>
D) 9.4 units
Answer:
(- 8, - 17 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 7 → (1)
y = x - 9 → (2)
Substitute y = 3x + 7 into (2)
3x + 7 = x - 9 ( subtract x from both sides )
2x + 7 = - 9 ( subtract 7 from both sides )
2x = - 16 ( divide both sides by 2 )
x = - 8
Substitute x = - 8 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = - 8 - 9 = - 17
Solution is (- 8, - 17 )
