Answer:
Each ticket cost $9.50
Step-by-step explanation:
4x+6.25=44.25
-6.25. -6.25
4x=38
x=9.50
1.
Answer is B.
2.
y = -4x - 7
x-intercept where y = 0,
0 = -4x - 7
-4x = 7
x = -7/4
y-intercept where x = 0,
y = -4(0) - 7
y = -7
Answer is C.
3.
Answer is none of the above.

Answer:
Step-by-step explanation:
3x%2B4y=12 Start with the given equation
4y=12-3x Subtract 3+x from both sides
4y=-3x%2B12 Rearrange the equation
y=%28-3x%2B12%29%2F%284%29 Divide both sides by 4
y=%28-3%2F4%29x%2B%2812%29%2F%284%29 Break up the fraction
y=%28-3%2F4%29x%2B3 Reduce
Looking at y=-%283%2F4%29x%2B3 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=-3%2F4 and the y-intercept is b=3
Since b=3 this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis
So we have one point
Now since the slope is comprised of the "rise" over the "run" this means
slope=rise%2Frun
Also, because the slope is -3%2F4, this means:
rise%2Frun=-3%2F4
which shows us that the rise is -3 and the run is 4. This means that to go from point to point, we can go down 3 and over 4
So starting at , go down 3 units
and to the right 4 units to get to the next point
Now draw a line through these points to graph y=-%283%2F4%29x%2B3
So this is the graph of y=-%283%2F4%29x%2B3 through the points and
Answer:
1 hour = 7.50
5 hours = 37.50
9 hours = 67.50
<h3>
answer is</h3>
7.50 per hour.
97.50 = 13 hours
Step-by-step explanation:
like this
or
= 7.50/1 hour

Answer:
No.
Step-by-step explanation:
First solve for y:-
x - y^4 = 1
y^4 = x - 1
y = +/- (x - 1)^(1/4)
This is a one-to-many relation . For a given value of y there 2 values of x.
So this is NOT a function.
