Answer:
x = 1, y = 2
Step-by-step explanation:
Original equations:
Substitute y and solve for x:
Plug in x to solve for y:
x = 1, y = 2
Note: You can also substitute x and solve for y, then plug in y to solve for x. I did not do that here.
Answer:
3/5
Step-by-step explanation:
There are 2 peaches + 1 apple + 3 oranges in the basket. There are a total of 5 fruits in the basket and 3 of them are oranges. If you randomly pick one the chances of you getting an orange if 3 out of 5.
The result is a line perpendicular to y=3x-2
This line has the following equation: y =mx + b, where m = slope
Remember that the product of the slopes of two perpendicular lines is always = -1 (or in other term one is the reciprocal inverse of the other) so the
first slope = 3 and the sope perpendicular to 3 will be - 1/3.
Then the new equation is y = - 1/3(x) + b
How to calculate b? This line passes through (6, 8), that
means (x=6 and y=8) . Plug these values in y = -1/3 (x)+b:3
8=(-1/3)(6) + b;
8= - 2 + b and b = 10
Te final equation is y = - 1/3.x+10 (answer A)
