Answer:
x = 2
y = -1
Step-by-step explanation:
Since it gives you the value of y already, just plug that into the equation, like so:
y = 4x - 9
x - 3 = 4x - 9
<em><u>Subtract the x from both sides:</u></em>
x - 3 = 4x - 9
-x - x
__________
-3 = 3x - 9
<em><u>Then, add 9 to both sides:</u></em>
-3 = 3x - 9
+9 + 9
________
6 = 3x
<em><u>Divide both sides by 3:</u></em>
2 = x
<em><u>Now plug in x for y:</u></em>
y = x - 3
y = 2 - 3
y = -1
Answer:
<h2>(90Degree)(0.3Degree/1min) = 300min</h2><h2>since 60min = 1hr</h2><h2>(300min)(1hr/60min) = 5hrs</h2>
Answer: a = 36 and b = 9
Explanation:
(6x-3)(6x+3)
= 36x² - 18x - 18x - 9
= 36x² - 9
(6x-3)(6x+3) = ax² - b
36x² - 9 = ax² - b
a = 36 and b = 9

Answer: 4,320 inches cubed.
Step-by-step explanation:
step 1----- Volume of 1 canvas box
Volume of solid for a rectangular box = Length x width xHeight
where Length= 12inches,
Width= 10 inches
Height= 12 inches
Volume of a Canvas box= 12 X 10 X 12= 1440 inches cubed
Step 2== Volume of 3 canvas boxes
1 canvas box = 1440 inches cubed
therefore 3 canvas boxes =
1440 x 3= 4320 inches cubed.
