Answer:
the first is true
Step-by-step explanation:
X + y + z = 32 * 3
27 + 27 + x = 96
X = 54
2x = 108
Average of x and 2x = (54+108) / 2 = 164 / 2 = 82
Average of X and 2X = 82
Answer:
m = 10 , n = 5
Step-by-step explanation:
using the cosine and tangent ratio in the right triangle and the exact values
cos45° =
and tan45° = 1 , then
cos45° =
=
=
( cross- multiply )
m = 5
×
= 5 × 2 = 10
-----------------------------------------
tan45° =
=
= 1 , then
n = 5
Answer:
Any points on the line y=2/5 x - 6/5. See picture below.
Step-by-step explanation:
Convert the equation to slope intercept form and graph it.
2x - 5y = 6
-5y = 6 - 2x
y = -2/-5 x + 6/-5
y=2/5 x - 6/5.
Locate each of the points listed on the graph. If they are a part of the line, then they are solutions.
