Answer:
I would recommend the website symbolab.com it really helps
Step-by-step explanation:
<A = 115 degrees, <C = 50 degrees
<A+<B+<C = 180 degrees
substitute with the given values: 4x - 13 + 15 + x + 18 = 180 degrees
Solve: x = 32 degrees
Substitute back in for <A : 4(32) - 13 = 115 degrees
Substitute back in for <C: 32 + 18 = 50 degrees
20:46 or 20 to 46
There are 20 girls on the team so theres your first number then you add the girls and boys to get the total number of players (46) and write out your ratio
Answer: option 4 x < 175
x/5 < 35
multiply both sides by 5
x < 175
(i can’t do the correct symbol but you get the idea)
B) 72
The n-th term of an arithmetic sequence An = a1 + (n - 1) d
Given :
a28 = 423/4 and d = 5/4
So
a28 = a1 + (28 - 1)5/4
Now plug in a28 = 423/4
423/4 = a1 + 27(5/4)
a1 = 423/4 - 27(5/4)
= 423/4 - 135/4
a1 = (423-135)/4
a1 = 288/4
a1 = 72
Thank you.
What is the domain of the given function?
{(3,-2), (6, 1), (-1, 4), (5,9), (-4, 0);
O {x | x= -4,-1, 3, 5, 6}
O {yl y = -2,0, 1,4,9}
O {x|x = -4,-2, -1,0, 1, 3, 4, 5, 6, 9}
O y y = 4,-2, -1, 0, 1, 3, 4, 5, 6, 9}

To solve, first plug in 4 as your x value for your g(x) equation.
Next, plug in the value of g(4) into your f(x) equation for x.
