Answer:
x = 2
Step-by-step explanation:
Solve the two equations simultaneously....whereby you substitute y = 2x - 6 from the above equation into the second equation...
where...; 5x + 10(2x - 6) = -10
5x + 20x - 60 = -10...then move the variables with x to one side...
5x + 20x = -10 + 60
25x = 50
;Therefore...the value of x at intersection point = 2
Answer:
a
Step-by-step explanation:
because they are vertical angles they are equal to each other so we write the equation 132=5x+7
step 1 subtract each side by 7
125=5x
step 2 divide each side by 5
x=25
Number of female students that got an A: 13
total number of female students: 38
13 divided by 38= 34%
Step-by-step explanation:
is it's total displacement divided by the total time taken.
Problem 1
<h3>Answer: D) 2pi</h3>
-------------------
Explanation:
The given table we have is

If you were to graph all those points and draw a cosine curve through them, then the function you should get is

The B coefficient is 1, so that leads to a period of
T = 2pi/B
T = 2pi/1
T = 2pi

Problem 2
<h3>Answer: C)
343.134 yards</h3>
-------------------
Explanation:
Draw out a triangle with these properties
- side a = 270
- side b = 170
- angle C = 100
We'll use the law of cosines to find side c
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 270^2 + 170^2 - 2*270*170*cos(100)
c^2 = 117740.902710
c = sqrt(117740.902710)
c = 343.133943
c = 343.134

Problem 3
<h3>Answer: A) 2</h3>
-------------------
Explanation:
If you started with y = sin(x) and applied the transformations stated, then you should end up with 
From here, plug in x = 0 to find the y intercept.
