Answer:
x = 9
Step-by-step explanation:
Substitute y=6 into 2x+3y=36
2x+3(6) =36
2x + 18 = 36
2x = 18
x = 9
Answer:
Step-by-step explanation:
y = 3x + 2
randomly select three x values and find the y's
3(-2) + 2 = -4
3(0) + 2 = 2
3(1) + 2 = 5
Answer:
<h2>m = 21, b = 5 → y = 21x + 5</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, b)</em>
The formula of a slope:
=====================================
From the table we have y-intercept (0, 5) → <em>b = 5 </em>and other point (1, 26).
Calculate the slope:
-2 because the line goes through -2
Answer:
$63.45
Step-by-step explanation:
first, find 470% of 15. 470*15=$70.50. then, find 10% of it. 70.50 divided by 10 = $7.05. then subtract it from the new price to get the final price. 70.50 - 7.05 = $63.45
