Answer:
y < 106
Step-by-step explanation:
Step 1: Add 21 to both sides.
Therefore, the solution is y < 106.
To graph it on a graph:
- circle 106 on the graph- DO NOT FILL IN THE CIRCLE
- point the arrow to the left direction
Okay, so supplementary angles = 180 degrees.
Starting equation : 4y + 7 + 9y + 4 = 180
Combine like terms : 13y + 11 = 180
Subtract 11 from both sides : 13y = 169
Divide 13 from both sides : y = 13
Insert y value into original m<2 equation : 9(13) + 4
Solve : 121 degrees
If you want to check your work, all you have to do is insert y value into original m<1 equation and then add both m<1 and m<2. If they equal 180, your answer is correct.
4(13) + 7 = 59
59 + 121 = 180

Answer:
40 ft
Step-by-step explanation:
The post is 8/12 = 2/3 as tall as the shadow is long. We expect the same relationship holds for the tree.
tree height = (2/3)(shadow length) = (2/3)(60 ft) = 40 ft
The tree is 40 feet tall.
Answer:
-38
Step-by-step explanation:
-51 + 13(-4h + 57)^2
- Subsitute the value of h into the variable.
-51 + 13 [-4(14) + 57]²
- According to BEDMAS, solve the brackets first.
-51 + 13 (-56 + 57)²
-51 + 13(1)²
-51 + 13(1)
-51 + 13
= -38
