Answer:
Step-by-step explanation:
39²=1521
80²=6400
39²+80²=1521+6400=7921
87²=7569
7921≠7569
so it is not aright angled triangle.
Answer:
D is the correct choice
Step-by-step explanation:
To get the y-intercept, we write the equation in the standard form
The standard form is ;
y = mx + b
So we have to rewrite the equation this very form
Thus, we have that;
0.05y = 0.4x + 1.25
we simply isolate the y value
To do this, we divide through by 0.05 and the y-intercept value will be ;
1.25/0.05 = 25
This would be an upside down parabola with a vertex at (0, 3).
To complete the chart, just plug x into the equation and evaluate.
Here is the completed table:
x y
-3 -15
-2 -5
-1 1
0 3
1 1
2 -5
3 -15
Answer:
$1,699.15
Step-by-step explanation:
1,999.00 x 0.15= 299.85
1,999-299.85= 1,699.15
