Answer:
y=4x+5
Step-by-step explanation:
You have your mx already: (mx is slope)
y=4x
And you have your b already: (b is y-intercept)
+5
Combine equations: (Solve)
y=4x+5
Hence, the correct answer is y=4x+5
Answer:
10. Expanded vertically by 3, shifted left 2 and up 4.
11. Shifted right 6 and up 7.
Step-by-step explanation:
This sort of question involves matching patterns. You need to know what the various transformations look like, and what that means for a specific parent function.
Here are the transformations used in this problem:
- f(x -a) . . . . shift f(x) to the right by "a" units
- f(x) +a . . . . shift f(x) up by "a" units
- a·f(x) . . . . . vertically scale f(x) by a factor of "a"
For these problems, the parent function is f(x) = 1/x.
__
10. The multiplier of 3 in the numerator (3/x) means the function has been scaled vertically (expanded) by a factor of 3.
The replacement of x with x+2 means the function has been shifted to the right by -2 units. That is the same as shifted left 2 units.
The addition of 4 to the function value means the function has been shifted up by 4 units.
__
11. We note the numerator is still 1, so there is no vertical expansion. The replacement of x with x-6 means a right shift by 6 units. The addition of 7 to the function value means a shift up by 7 units.
Answer:
8x-8z
Step-by-step explanation:
6x-3y-z+2x+3y-7z this equation goes to every step below.
since there are 2 opposites, add up to zero, remove them from the expression
-> 6x-z+2x-7z. (-3y. +3y)
collect like terms.
-> 8x-z-7z. (6x. +2x)
collect like terms.
-> 8x-8z
Answer:
Step-by-step explanation:
I have to go with 9r-18= -27 is my answer for your math
Hey there!
2x+1=73.
2x=72.
x=36<span>.
</span>
So the 2 consecutive numbers are 72 and 36!
Hope this helps! :)
