Answer:
<em>A) Points earned = 15 - 6</em>
<em>B) Sandy didn't make it to the next level since her score was 9 and she needed a minimum of 10</em>
Step-by-step explanation:
To advance to the next level in her game, Sandy must score at least 10 points.
She scores 15 points for correct matches
She scores -6 points for incorrect matches.
A. The amount of points earned by Sandy in the game is the sum of both scores:
points earned = 15 - 6
points earned = 9
B. Unfortunately, Sandy didn't make it to the next level since her score was 9 and she needed a minimum of 10
Answer:
The vertex is (-1, 4), the domain is all real numbers, and the range is y less than 4
Step-by-step explanation:
Given
Solving (a): The vertex;
Assume the general form of a function is
The vertex is determined by
By comparison, we have:
Solve for h, we have:
So, the vertex is:
The domain; x is all real numbers
From the function;
This can be rewritten as:
This implies that:
Whatever the value of is, it will be subtracted from 4 to give y or f(x);
Hence:
y is less than 4
<em>Option B answers the question</em>
289 estimated is 290
7 estimated it 10.
290 times 10 is 2,900
Kerry and Luke biked a total of 18 miles in one weekend. Kerry biked 4 miles more than Luke. How far did each bike? Write a system of equations and solve.
let x - kerry y - luke x + y = 18 x = y +4 y + 4 + y = 18 2y = 14 y = 7 x = 11
