Answer:
x = 0, y = 2
Step-by-step explanation:
Substitute the first equation into the second equation so 3x + 3(x+2) = 6. Simplify this to get x = 0. Plug x = 0 back into the first equation to get y = 2.
Answer:
1,092 cm²
Step-by-step explanation:
Smaller box:
Length = 24 cm
Wrapping paper = 936 cm²
Bigger box:
Length= 28 cm
Wrapping paper = x cm²
Box : wrapping paper = 24 cm : 936 cm²
Box : wrapping paper = 28 cm : x cm²
Equate both ratios to find x
24 : 936 = 28 : x
24/936 = 28/x
Cross product
24 * x = 936 * 28
24x = 26,208
x = 26,208 / 24
x = 1,092 cm²
Bigger box:
Length= 28 cm
Wrapping paper = 1,092 cm²
Answer:
-1.118 is the required value of tan theta
to graph a LINEar equation, since it's just a straight line, recall, to draw a straight line all you need is two points.
so we can just pick two random "x" values, hmmmmm say x = 0, what's "y"?
y = 7(0)-7 => y = -7....................................... so that gives us the point (0, -7)
hmmm x = 2, what is "y"?
y = 7(2) - 7 => y = 14-7 => y = 7................. so we get the point (2, 7).
then just plot those, and run a line through them.
