Answer:
<u>x = -3</u>
Step-by-step explanation:
-5x + 9 = 24
move the nine to the other side
-5x = 15
divide
x = -3
Combine like terms, you would get -1+9 which your answer would be 8
Answer:
The rule used to reflect Δ ABC to its image is Reflect over y = x ⇒ B
Step-by-step explanation:
- If the point (x, y) reflected across the x-axis
, then its image is (x, -y)
- If the point (x, y) reflected across the y-axis
, then its image is (-x, y)
- If the point (x, y) reflected across the line y = x
, then its image is (y, x)
- If the point (x, y) reflected across the line y = -x
, then its image is (-y, -x)
From the given figure
∵ The coordinates of point A are (-4.5, 6)
∵ The coordinates of point A' are (6, -4.5)
→ The coordinates are switched ⇒ 3rd rule
∴ Point A is reflected over the line y = x
∴ Δ ABC is reflected over the line y = x
∴ The rule used to reflect Δ ABC to its image is Reflect over y = x
<em>Note: Point B' on the graph should be C' and point C' should be B' (correct it)</em>
The equation representing the cost of 6 chairs and a table is:
6x + x + 50 = 750
⇒
7x = 700
This equation is true for x = 100 because:
7(100) = 700
So, the cost of one chair will be $100.
Cost of table is $50 more than a chair, so the cost of one table is $150.
So the answers are:
$ 100
$ 100
$ 150
Answer:
26
Step-by-step explanation:
50-20=30+1=31-7=26
