Answer:
The supposition is incorrect.
Step-by-step explanation:
The growth rate of a child is not constant, so height versus time does not look like a straight line. Nothing is wrong with the prediction made using the false assumption. You can conclude anything you like when you start with a false premise.
-7(-1-m)
First: You would distribute your -7 to your -1 and your -m
Note: A positive and a positive makes a negative.
You would get: 7m+7 as your answer

Answer:
3
-2x +5=0
Step-by-step explanation:
Combine liked terms:
3
+5x+x-1x+6+2=7x+3
3
+6x-1x+8=7x+3
3
+5x+8=7x+3
Subtract 3: 3
+5x+8-3=7x+3-3
3
+5x+5=7x
Now subtract 7x:
3
+5x+5-7x=7x-7x
If you want combine liked terms:
3
-7x+5x+5=0
3
-2x+5=0
Hope this helps!
Answer:
360 - Y
Step-by-step explanation:
From the information provided in the question, we will understand that the question lacks detailed information.
Given that:
The total number of actual students on the A honor roll = 360
To find the number of students on the A honor roll of 8th graders;
Let denote Y to represent the total number of students who exist on the A honor roll except for the 8th graders.
Then:
The number of 8th graders = all number of students on are on the A honor roll - Y
The number of 8th graders = 360 - Y
If Y is known, then the number of the 8th graders can be fully determined.
Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.
So let's do cos(35°) = 15cm / x
cos(35°) = 0.8 (1 dp)
x = 15 cm / cos(35°)
x = 18.3 cm (1 dp)
