Answer 1

Answer: sub

x=5-y
nice
sub 5-y for every x you see in other equation

5(5-y)-2y=6
25-5y-2y=6
25-7y=6
minus 25 both sides
-7y=-19
divide both sides by -7
y=19/7

sub back

x=5-y
x=5-19/7
x=35/7-19/7
x=16/7

(16/7,19/7)

first one

50/8 converted as a mixed number

Answers

50/8

Simply divide 8 into 50. That is 6. Because 8 *6 = 48.

There would be a remainder of 2.

So 50/8 = 6 whole number 2/8.

So the answer = 6 whole number 2/8. As mixed fraction.

You can reduce the 2/8 to 1/4.

So 6 whole number 1/4 is also correct.

6 1/4 because do 50÷8=6 (remainder: 2)

So it is 6 2/8. Simplify it and it will be 6 1/4.

The height of water shooting from a fountain is modeled by the function f(x) = -4x2 + 24x - 29 where x is the distance from the spout in feet. Complete the square to determine the maximum height of the path of the water. -4(x - 3)2 - 29; The maximum height of the water is 3 feet.
-4(x - 3)2 - 29; The maximum height of the water is 29feet.
-4(x - 3)2 + 7; The maximum height of the water is 7 feet.
-4(x - 3)2 + 7; The maximum height of the water is 3 feet.

Answers

yo don't need max height
yo use 'find vertex' equestion

since leading term is negative, this equation has a max

the vertex is the max
in the form
y=ax^2+bx+c
vertex=-b/2a

-4x^2+24x-29
a=-4
b=24

vertex=-24/(2*-4)=-24/-8=3

max height is 3 feet
dunno wat the compete square is

I can do that fo ou though
move -29 off to side and undistriute -4
-4(x^2-6x)-29
complete the square, take 1/2 of -6 an square it andadd 0
-4(x^2-6x+9-9)-29
complete square
-4((x-3)^2-9)-29
move the 9 out by distributing the -9 to the -4
36
-4(x-3)^2+36-29
-4(x-3)^2+7

answer is 3rd option

Answer: The correct answer for this question is option...

(C) −4(x − 3)2 + 7; The maximum height of the water is 7 feet.

a population of insects doubles every month. If there are 100 insects to start with, how many will there be in 7 month

Answers

If at the end of every month the population dubbuls then at the end of 7 month there will be 12,800

month1)200

month2)400

month3) 800

month4) 1600

month5) 3200

month6) 6400

month7)12800

Final answer:

The population of insects is doubling each month. To figure out the population after 7 months, we can use the formula for exponential growth, 2^n, where n is the number of months. Using this formula, after 7 months, there will be 12,800 insects.

Explanation:

The population of insects is doubling each month, so the insect population is growing exponentially. To calculate the population after 7 months, you can use the formula for exponential growth, which is 2^n, where n is equal to the number of time periods, in this case, months.

After 1 month, the population is 100 * 2 = 200. After 2 months, the population is 200 * 2 = 400, and so on. After 7 months, we can calculate as follows:

100 * 2^7 = 100 * 128 = 12800 insects. So, after 7 months, there will be 12,800 insects if the population doubles each month.
