Answer:
4 and 6
Step-by-step explanation:
First, let's find all the pairs that add up to 10.
- 1 + 9, 2 + 8, 3 + 7, 4 + 6, and 5 + 5
Next, we find the difference between the addends for each pair.
- 9 - 1 = 8
- 8 - 2 = 6
- 7 - 3 = 4
- 6 - 4 = 2
- 5 - 5 = 0
As you can, see the numbers that add to 10 and have a different of 2 is 4 and 6.

Answer: B) Only the first equation is an identity</h3>
========================
I'm using x in place of theta. For each equation, I'm only altering the left hand side.
Part 1
cos(270+x) = sin(x)
cos(270)cos(x) - sin(270)sin(x) = sin(x)
0*cos(x) - (-1)*sin(x) = sin(x)
0 + sin(x) = sin(x)
sin(x) = sin(x) ... equation is true
Identity is confirmed
---------------------------------
Part 2
sin(270+x) = -sin(x)
sin(270)cos(x) + cos(270)sin(x) = -sin(x)
-1*cos(x) + 0*sin(x) = -sin(x)
-cos(x) = -sin(x)
We don't have an identity. If the right hand side was -cos(x), instead of -sin(x), then we would have an identity.
Answer:
slope = -9/2
Explanation:
The form of the slope-intercept equation is:
y = mx + c
where:
m is the slope
c is the y-intercept
The given is:
y = -9/2 x
Comparing the given with the general form, we will find that:
m is the slope = -9/2
c is the y-intercept = 0
Hope this helps :)
y = -9/2
Answer:
x ≥ 25
Step-by-step explanation:
In the seventh grade, fifty students are trying for sports supplies to raise at least $2000. They already have $750.
Let us assume that each student has to raise $x more to meet the goal.
Then, a total of 50 students will raise $50x more.
Therefore, the inequality to solve for x will be
750 + 50x ≥ 2000
⇒ 50x ≥ 1250
⇒ x ≥ 25 (Answer)
