Answer:
y=-3.5x+9
Step-by-step explanation:
the slope is determined by the y1-y2/x2-x1 which is equaled to -5-2/4-2 which is equaled to -7/2 which is -3 1/2 which is your m value in y=mx+b and you graph to get your b value (y-intercept) which is 9
Answer:
450 pennies
Step-by-step explanation:
2/3 ➡ 3/3 × 2/3 = 6/9
let's call it 9x
the bank contains 6x after she removes 100 pennies 4x is left
which means 2x = 100 pennies and x = 50 pennies
therefore the bank can carry 50 × 9 = 450 pennies
The best statement that compares the length of time each ball is in the air is seen in the second option.
<h3>What is
the function of a quadratic equation?</h3>
A quadratic function follows the condition: f(x) = ax² + bx + c. Here (a, b, and c) are real numbers and a ≠ 0.
From the given information:
- The function f(t) = -16t² +64t + 5 models the height of a ball
Where;
- time (t) ⇒ seconds
- height (h) ⇒ feet
The table given is as follows:
Time (in seconds) height, g(t) in feet
0 4
1 36
2 36
3 4
From the table, when t = 0, the function becomes:
f(t) = -16t² +64t + 5
f(t) = -16(0)² + 64(0) + 5
f(t) = 5
Therefore, we can conclude that the best statement that compares the ball is: f(t) is in the air for about 5 seconds, and the ball represented by g(t) is in the air for about 3 seconds.
