Answer:
7.19
Step-by-step explanation:
56.45
- 49.26
--------------
07.19
x-intercept(s): (1/2, 0) or (0.5, 0)
y-intercept(s): (0, −2)
The answer is <span>f(x) = 2x2 + 3x – 3
</span>
f(x) = ax² + bx + c
a - the leading coefficient
c - the constant term
<u>We are looking for a = 2, c = -3</u>
Through the process of elimination:
The first (f(x) = 2x3 – 3) and the third choice (f(x) = –3x3 + 2) have x³ so these are not quadratic function.
In the function: <span>f(x) = –3x2 – 3x + 2
</span>a = -3
c = 2
In the function: f(x) = 2x2 + 3x – 3
a = 2
c = -3
Andrew will run 32 miles.
Explanation:
If you divide the time Andrew ran by the miles he ran, you’ll get 7.5 minutes per mile. Then, if you divide 240 minutes by 7.5, you get 32 miles.
Answer:
The predicted value of x = 2
Step-by-step explanation:
y = 4.2x - 3 is the given equation.
Now, y = 5.4
Putting in the above equation, we get
5.4 = 4.2x - 3
or, 5.4 + 3 = 4.2x
or, 8.4 = 4.2 x
⇒ x = 8.4/4.2
⇒ x = 2
