<span>y = slope*x + y-intercept;
</span>We can rewrite our equation in a shorter form : y = mx + b;
y = x + 2 ; m1 = 2 and b1 = 2;
y = -x + 6; m2 = -1 and b2 = 6;
<span>Set the two equations for y equal to each other:
</span>x + 2 = -x + 6 ;
<span>Solve for x. This will be the x-coordinate for the point of intersection:
</span>2x = 4;
x = 2;
<span>Use this x-coordinate and plug it into either of the original equations for the lines and solve for y. This will be the y-coordinate of the point of intersection:
</span>y = 2 + 2 ;
y = 4;
<span>The point of intersection for these two lines is (2 , 4).</span>
Multiply the numerators together and the denominators:
2/7 x 5/6 = (2x 5) / (7x6) = 10/42 this can be reduced to 5/21
The answer is 5/21
-4/5 x 7/10 = (-4x7) / (5x 10) = -28/50
This can reduce to -14/25
Answer:
y = x + 3/5
Step-by-step explanation:
1. Label this function 'y': y = x - 3/5
2. Interchange x and y: x = y - 3/5
3. Solve this for y: y = x + 3/5
This last result is the inverse of the given function.
Answer:
Step-by-step explanation:
So if a number is 5 or greater you round up but if the number is 4 or less you round down so the number 6 is above five so you would round the 6 to 10 therefore making it 7.8 instead of 7.76
