Answer:
y = 1/2x + 2
Step-by-step explanation:
for x=10, y=7
for x=20, y=12
for x=30, y=17
y = 1/2x + 2
Answer:
Greg used 1/10 more meters
Step-by-step explanation:
3/5=6/10
1/2=5/10
The Correct option is ~ B
Let's find the slope (m) using points (2 , 1) and (0 , -3)
hence, slope = 2
now, by Observing the given graph we can infer that the given line cuts the y - axis at point (0 , -3), so value of y - intercept (c) = - 3
[ y - coordinate of a point when x - coordinate is equal to 0 is the value of y - intercept of a line ]
And, we know the general equation of line in slope - intercept form is ~
now, let's plug the value of slope (m) and y - intercept (c) in the general equation to find the equation of line in slope intercept form ~
Answer:
Step-by-step explanation:
Given
Required
The values of m and n
For x - 1;
we have:
So:
Collect like terms
Because x - 1 divides the polynomial, then P(1) = 0;
So, we have:
Add 9 to both sides
--- (1)
For x + 2;
we have:
So:
Collect like terms
x + 2 leaves a remainder of 36, means that P(-2) = 36;
So, we have:
Collect like terms
Divide through by 2
--- (2)
Add (1) and (2)
Divide by 3
Substitute in (1)
