Answer: 2.1925153x10 to the 3rd
Step-by-step explanation: hope it helps
x intercept = where the function crosses the x axis (x,0)
y intercept = where the function crosses the y-axis (0,y)
A. y=7/2x-2
x intercept , replace y by 0 and solve for x:
0 =7/2x-2
2= 7/2 x
2 / (7/2) = x
x= 4/7
y-intercept, replace x by 0 and solve for y
y= 7/2x-2
y= 7/2 (0) -2
y=-2
B.
x-intercept:
x=-3
y-intercept
0=-3
It doesn't have a y-intercept.
I'll write the equation again with the blanks filled in.
1/2 of 2/3 = 1/2 of two thirds = one third
2/3 is read as two thirds.
Half of 2/3 is 1/3, because 1/3+1/3=2/3
Hope this helps!
Answer:
x = 675
Step-by-step explanation:
Collect terms and solve the resulting 2-step linear equation.
(x-355)+(x)+(80+2x)=2425 . . . . . given
4x -275 = 2425 . . . simplify
4x = 2700 . . . . . . . add 275
x = 675 . . . . . . . . . divide by 4
Answer:
x <= 1/4 (less than or equal to)
Step-by-step explanation:
In this equation, all you need to do is isolate the variable. To do this, you just move everything that isn't x to the right side. To get rid of the 4, divide both sides by 4. Your result will be x <= 1/4.
Note: Since we're dividing both sides by a positive number, we don't have to change the direction of the inequality. If you were to divide both sides by -1 you would have to reverse the inequality. Example:
x > 1 or 5 > 1
-x < -1 or -5 < -1
