Answer:
<h2>
A</h2>
Step-by-step explanation:
gradient = (-3+2)/(0-3)
gradient = 1/3
slope intercept form : y = mx + b
m is the gradient which we have found to be 1/3
b is the y intercept that can either be -2 or - 3 (both the y coordinates)
therefore the equation would be y = 1/3 x - 3 (A)
hope this helps :)
Answer:
0.58
Step-by-step explanation:
0.51+0.7=0.58
1+7=8+50=50=0.58
10 times .05 is 10.50 so $10.50
Let x represent invested money at 9% and y at 7%
Now we write system:
x+y = 6300
1.09*x + 1.07* y = 6300 + 493 = 6793
1.09x + 1.09y = 6867
Here we multiplied first equation with 1.09 and now we will subtract second from first:
0.02y = 74
y = 3700
x = 6300-3700 = 2600
Michael invested 2600 at 9% and 3700 at 7%
Yes, because 1/3 x 4 = 4/12
