Answer:
Subtract 10
Step-by-step explanation:
The first option, "take the ones digit", is obviously incorrect because the ones digit of 9 is not -1. The second one is incorrect because you are dividing by 2 and then adding 5. Dividing odd numbers by 2 will give you a decimal and a decimal plus an integer (the integer is 5 in this case) will still be a decimal (provided that the decimal is not an integer as well). However, both of the outputs are integers, so we know that the second one is wrong. The third one is wrong as well because 9 / 3 = 3, not -1. The last one is correct because 15 - 10 = 5 and 9 - 10 = -1.

You are playing basketball with your friends. The height (in feet) of the ball above the ground t seconds after a shot is released from your hand is modeled by the function f(t)= -16t^2 + 32t + 5.2. What is the value of t when the ball is released from your hand ?
Answers
Answer:
2.15 seconds
Step-by-step explanation:
Given the equation of the height (in feet) of the ball above the ground t seconds after a shot is released from your hand modeled by the function
f(t)= -16t² + 32t + 5.2 where t is in seconds.
Note that the value of the height at the point the ball is released from the hand is 0 feet.
To get value of t when the ball is released from your hand, we will substitute f(t) = 0 into the modeled equation as shown;
f(t)= -16t² + 32t + 5.2
-16t² + 32t + 5.2 = 0
Multiply through by 10
-160t² + 320t + 52 = 0
Dividing through by -4
40t² - 80t - 13 = 0
t = 80±√80²-4(40)(-13)/2(40)
t = 80±√6400+2080/80
t = 80±√8480/80
t = 80±92.09/80
t = 80+92.09/80
t = 172.09/80
t = 2.15 secs
Hence, the value of t when the ball is released from your hand is approximately 2.15seconds.

write an equation in slope intercept form of the line that passes through (0,2) (8,8)
Answers
Step-by-step explanation:
Hey, there!!
You can get your answer simply, just remember the two point formula,
Given, the points are (0,2),(8,8).
We have, Formula for two points is,
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1) [/tex]
Put all values here,
[tex](y - 2) = \frac{8 - 2}{8 - 0} (x - 0)[/tex]
[tex](y - 2) = \frac{6}{8} (x -0)[/tex]
[tex](y - 2) = \frac{3}{4} (x - 0)[/tex]
multiply (y-4) by 4 and (x-0) by 3.
[tex](4y - 8) = 3x[/tex]
Bringing 4y and -8 on same side of 3x.
[tex]0 = 3x - 4y + 8[/tex]
[tex]or \: 3x - 4y + 8 = 0[/tex]
Therefore, 3x-4y+8=0..... is the required equation.

Given f(x) = 7x - 4 and g(x) = -3x + 2, find (f+g)(x)
Answers
Answer:
[tex](f+g)(x) = 4x - 2[/tex]Step-by-step explanation:
f(x) = 7x - 4
g(x) = -3x + 2
To find (f+g)(x) add g(x) to f(x)
That's
[tex](f+g)(x) = 7x - 4 + (- 3x + 2) \\ = 7x - 4 - 3x + 2 \\ = 7x - 3x - 4 + 2[/tex]We have the final answer as
[tex](f+g)(x) = 4x - 2[/tex]Hope this helps you
Answer:
[tex]\Large \boxed{(f + g)(x) = 4x - 2}[/tex]
Step-by-step explanation:
We have two functions.
f(x) = 7x - 4
g(x) = -3x + 2
To find (f+g)(x), we have to find the sum of f(x) and g(x).
(f+g)(x) = f(x) + g(x)
(f + g)(x) = 7x - 4 + -3x + 2
Combining like terms.
(f+g)(x) = 7x - 3x - 4 + 2
(f + g)(x) = 4x - 2
After an exercise, Ali and Ben measured their heart rates. The ratio of their heart rates was 15:17 Bens heart beats 18 times per minute more than Ali. Calculate Ali heart rate
Answers
Answer:
Ali's heart rate is 135 times per minute.
Step-by-step explanation:
Let Ali's heart rate be denoted by x times per minute.
It is provided that Ben's heart beats 18 times per minute more than Ali.
The ratio of their heart rates was 15:17.
That is:
[tex]\frac{15}{17}=\frac{x}{x+18}[/tex]
Solve for x as follows:
[tex]\frac{15}{17}=\frac{x}{x+18}[/tex]
[tex]15(x+18)=17x\\15x+270=17x\\2x=270\\x=135[/tex]
Thus, Ali's heart rate is 135 times per minute.

Answer:
x = 15 and y = 30
Step-by-step explanation:
We see that 4x + 15 + 5x + 30 = 180.
We can solve for x:
9x + 45 = 180
9x = 135
x = 15.
We also see that 5x + 30 is equal to 3y + 15, so we can solve for y:
5x + 30 = 3y + 15
5 (15) + 30 = 3y + 15
3y = 75 + 30 - 15
3y = 90
y = 30.
