Answer:

Adult’s ticket = $ 18

Child’s ticket = $ 16

Step-by-step explanation:

Adults: x

Children: y

(3x + 4y = 118) * (2) = 6x + 8y = 236

(2x + 3y = 84) * (-3) = -6x - 9y = -252

Add both equations:

-y = - 16

y = 16

3x + 4(16) = 118

3X + 64 = 118

3X = 118 - 64

X = 54/3=18

What is the equation of the line that passes through (2, -7) and (-1, 2)?
SVETLANKA909090 [29]

Answer:

y = -3x - 1

Step-by-step explanation:

The slope intercept form of the equation of a line is:

y = mx + b

where m is the slope, and b is the y-intercept.

First, we find the slope of the line using the two given points.

m = slope = (y2 - y1)/(x2 - x1) = (2 - (-7))/(-1 - 2) = (2 + 7)/(-3) = 9/(-3) = -3

Now we plug in the slope we found into the equation above.

y = -3x + b

We need to find the value of b, the y-intercept. We use the coordinates of one of the given points for x and y, and we solve for b. Let's use point (2, -7), so x = 2, and y = -7.

y = -3x + b

-7 = -3(2) + b

-7 = -6 + b

Add 6 to both sides.

-1 = b

Now we plug in -1 for b.

y = -3x - 1

V-9/10v+6=11(hlp)this problem is confusing.
Valentin [98]
\frac{v-9}{10v+6}=11 \\\\ 11(10v+6)=v-9 \\\\ 110v+66=v-9 \\\\ 110v-v=-9-66 \\\\ 109v= -75 \\\\ \boxed{v=-\frac{75}{109}}
