5a3-5a2
Step-by-step explanation:
Answer:
45, 47
Step-by-step explanation:
Their average, 92/2 = 46, is the even integer between them. The two integers of interest are 45 and 47.
___
Any consecutive integers of the same parity (odd or even) differ by 2. If x is the smaller, then x+2 is the larger.
We suppose you're supposed to write the equation ...
x + (x+2) = 92
2x = 90 . . . . . . subtract 2
x = 45 . . . . . . . .the smaller integer is 45; the larger one is x+2 = 47.
If you graph y=7x-9 and y=3x-1 the two lines will intersect at one point. That is how you graphically "solve" the system of equations.
Both of these lines are of the form y=mx+b where m is the slope and b is the y-intercept.
So for y=7x-9, the slope is 7 and the y-intercept is -9
For y=3x-1, the slope is 3 and the y-intercept is -1
....
The solution for this system occurs when both coordinates are equal to each other so we can say:
7x-9=3x-1 subtract 3x from both sides
4x-9=-1 add 9 to both sides
4x=8 divide both sides by 4
x=2, making y=3x-1 become:
y=3(2)-1=6-1=5, so the solution to the system of equations is:
(2,5)
Answer:
slope is the gradient of a line. equation of a line and slope intercept form is y = mx + b where m equals the slope of the line and b is is the point on the y-axis that the line crosses. think of slope as the gradient of your stairs at home where The height (rise) of the stair is the y-axis and the length (run) of the stair is along the x-axis. let's say the rise of the stair is 6 in and the run of the stair is 9 in. The slope would then be the rise over the run or in our case 6 in over 9 in simplified that would be ⅔. let's imagine that our slope crosses the y-axis at 6 and our equation would be y = ⅔x + 6
