Answer:
C
Step-by-step explanation:
y + 2x + 10 = 4x + 5
y = 4x - 2x + 5 - 10
y = 2x - 5
Answer- C
Answer:
y = 6
x = 2
Step-by-step explanation:
rearrange the first equation in terms of x
x = (y - 2)/2
substiute x in the second equation
y = -5[(y-2)/2] +16
Now simpilify and solve for y
y = (-5y + 10)/2 +16
y = -5/2y + 5 + 16
y + 5/2y = 5 + 16
3.5y = 21
y = 6
Now substitue y in the first equation to solve for x
x = (6 - 2)/2
x = 2
The missing values are 2.5, 10 and 22.5
<h3>What is equation?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Using equation (y2-y1)/(x2-x1) to find the slope.
Now using two points as (5, 12.5) and (6, 15.00)
So, (15-12.5)/(6-5)
=2.5/1
=2.5
Hence, single ticket costs 2.5
For 2 tickets,
= 2.5×2=5
The cost of two tickets is $5
For 4 tickets,
= 4×2.5=10
The cost of four tickets is $10
For 9 tickets,
= 2.5×9=22.5
The price of nine tickets is $22.5.

Sin 2 x + 2 sin x = 0
2 sin x cos x + 2 sin x = 0 / : 2
sin x cos x + sin x = 0
sin x ( cos x + 1 ) = 0
sin x = 0, cos x + 1 = 0, cos x = - 1;
Answer:
x = 0, or x = π
