Answer:
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.

Answer: (0.1) m= -4/3 y= -4/3*x+1
Step-by-step explanation:
Our equation is wriiten this way : y=mx+b where m is the slope and b a constant
- let f be our function
- m = (f(6)-f(3))/6-3= (-7-(-3))/3 = -4/3
- so: y=-4/3x+b
To get b we need to replace y and x by the coordinates of a point :
- (0.1) an easy one
- 1 = -4/3*0+b
- 1= b
- so: y= -4/3*x+1
The intercepts with the y-axis are the images of 0
we can see from the table that f(0) = 1 so (0.1) is the intercept with the y-axis
Answer:
The correct quotient is 3.
I think Derek has mistaken to divide by .
Step-by-step explanation:
We have to check the quotient of .
Part A:
Now, .
=
So, the correct quotient is 3.
Part B:
Derek says that the quotient is .
So, I think Derek has mistaken to divide by . (Answer)
Answer:
x-intercept = 30/6 = 5
y-intercept = 30/5 = 6/1 = 6.00000
Step-by-step explanation:
calculate the Y-intercept:
Notice that when x = 0 the value of y is 6/1 so this line "cuts" the y axis at y=6.00000
y-intercept = 30/5 = 6/1 = 6.00000
Calculate the X-Intercept :
When y = 0 the value of x is 5/1 Our line therefore "cuts" the x axis at x= 5.00000
x-intercept = 30/6 = 5
Answer:
x=-8
Step-by-step explanation:
collect like terms
-5x=40
divide both sides of the equation by -5
so the answer would be x=-8
