Answer:
Step-by-step explanation:
2y + 4 = 0 <em>subtract 4 from both sides</em>
2y = -4 <em>divide both sides by 2</em>
y = -2
The slope-intercept form of an equation of a line:
y = mx + b
m<em> - slope</em>
b<em> - y-intercept → (0, </em><em>b</em><em>)</em>
In the equation
y = -2
<em>slope: </em><em>m = 0</em>
<em>y-intercept: </em><em>b = -2 → (0, -2)</em>
<em />
<em>y = -2 - it's a horizontal line</em>
Answer:
49%
Step-by-step explanation:
465 + 485 = 950
465/950 = .489
.489 * 100 = 48.9, round up for 49 to get 49%, since it's only focused on people who tested positive, you would only have to compare the people in that column
7. Let x be the money she began with, then
1/3 (x - 4/5 x) = 15
1/3 (1/5 x) = 15
1/15 x = 15
x = 15 * 15 = $225
Therefore, she started with $225
Let x be the number of students surveyed, then
1/2(x - 1/3x - 1/6x) = 9
1/2(1/2x) = 9
1/4x = 9
x = 4 * 9 = 36
Therefore, the number of students surveyed is 36.
