The number of taxi accidents is approximated by y=−143.3x2+1823.3x+6820 and the number of injuries is approximated by y=−416.72x

antiseptic1488 [7]

To get for the taxi accidents in 1998, we must note that x = 8. Therefore using the equation y=−143.3x2+1823.3x+6820 , we can calculate for the number of taxi accidents.

y = -143.3 * (8)^2 + 1823.3 * 8 + 6820

y = 12,235.2

There were about 12,235 taxi accidents in 1998.

There are 172 South American animals in the Springdale zoo. That is 45 more than half the number of african animals in the zoo.

patriot [66]

N=number of African animals in the zoo;
we suggest this equation:
172=45+n/2
Least common multiple=2
172*2=45*2+n
344=90+n
n=344-90
n=254

Answer: there are 254 African animals in the zoo.

a line goes through the point(6,-2)and has a slope of -3 what is the value of a if the point (a,7) lies on the line

yaroslaw [1]

Answer:

The value of a is "3", to complete the coordinate point (3,7) on the line.

Step-by-step explanation:

We are given the slope of the line, and also one point through which the line passes. Therefore, we can find the actual equation of the line by using the slope-point form of the line:

$y-y_0=m(x-x_0)\\y-(-2)=(-3)(x-6)\\y+2=-3x+18\\y=-3x+18-2\\y=-3x+16$

Now, we need to find which value of "x" renders a y-value of "7", to complete the coordinate pair (a, 7) as requested. Therefore, we ask for the y-value in the previous equation to be "7", and solve for its associated x-value:

$y=-3x+16\\7=-3x+16\\7-16=-3x\\-9=-3x\\x=\frac{-9}{-3} \\x=3$

Therefore, x = 3
