exis [7]3 years ago
7 0

Answer:

-49

Step-by-step explanation:

multiply 7 with 7 then i with i and lastly multiply the result numbers

7i × 7i ➡ 7 × 7 = 49

i × i = i^2

49 × i^2 = 49i^2

i^2 = -1 ➡ 49 × (-1) = -49

Verticalset the denominator of the function equal to zero and solve for 'x', x is the vertical asymptote.Horizontalsubtract the amount of x's in the numerator from the number of x's in the denominator, then do one of the four things to find y: and if the answer is negative, then y=0 does that help any?if the answer is 0, then y= a/b (ax/bx)<span>If the answer is greater than positive 1, then there is no horizontal asymptote
</span>ObliqueIf the answer is 1, then it is oblique. use long division with the denominator as the divisor of the overall function given (not the fraction) and y= ax+/- b 
Does this help at all

Write an equation of the line in slope-intercept form.
fiasKO [112]

Answer:

y=mx+b where m is the slope and b is where the line crosses the y axis.

THe line crosses the y axis at 0, 2 so 2 = b

the slope is how many units the point goes up/down and to the left/right from the y intercept. From 0, 2 to 3, 3 the point goes up 1 and over to the right 3 times. rise/run is slope so 1/3 is the slope:

y=1/3x+2

Are the expressions 8a - 3b - (2a + 4b) and 6a + b equivalent?
Margaret [11]

Answer:

No.

Step-by-step explanation:

Let's start by simplifying the first expression:

8a-3b-(2a+4b)

Remove the parentheses:

8a-3b-(2a)-(4b)\\8a-3b-2a-4b

Combine like terms:

8a-2a-3b-4b\\6a-7b

6a-7b\neq 6a+b (Assuming that none of the variables are equivalent to 0)
