y = (1/2)x - 4
Step-by-step explanation:
The equation of the given line is
y = -2x + 13
The equation of the perpendicular line that we need must have a slope of 1/2 and passes through (2, -3) so the form should be
y = (1/2)x + b
To solve for b, use the point (2, -3)
-3 = (1/2)(2) + b ---> b = -4
Therefore, the equation that we need has the form
y = (1/2)x - 4
Answer: The equation to find the number of cards could be: c = 300 + 17d, where c equals the total number of cards and d represents the number of days.
The 300 value is the starting amount of cards that Rudy has.
The 17 represents the number of cards that he is getting per day. It started at 15 because that is the amount in a pack of cards. However, he trades one to his brother and gets 3 in return.
15 - 1 + 3 = 17 extra cards per day
Answer:
Its E.(3 × 4) + 1 × (2 × 5) + 3.
Since we are to complete the square, therefore I believe
the correct given should be:
x ^ 2 – 11 x
Take note of the symbol ^ which denotes that 2 is an exponent
of x.
The general form of a binomial equation is in the form of:
a x^2 + b x + c
Where in this case:
a = 1
b = -11
c = unknown
To complete the square, we have to find for the value of
c. This is calculated using the formula:
c = (b / 2) ^ 2
c = (-11 / 2) ^ 2
c = 30.25
Therefore the complete equation is:
<span>x ^ 2 – 11 x + 30.25</span>
Answer:
8x+3y
Step-by-step explanation:
1. Find like terms: 5x and 3x share the same constant "x" so you can combine them. There is nothing to combine with the 3y since there is no other term with the constant "y".
2. Rearrange to make it easier to see: 5x+3x+3y
3. Add the 5x and 3x: 8x+3y
