The answer is 5x + 10 because you have to times 5 by everything in the parenteses
Answer:
30% members have voted.
Step-by-step explanation:
Given:
Number of members voted = 3
Number of members didn't vote = 7
We need to find what percentage of people voted.
Solution:
First we will find the total number of members in the election.
Now we can say that;
The total number of members in the election is equal to sum of Number of members voted and Number of members didn't vote.
framing in equation form we get;
The total number of members in the election =
Now we will find the percentage of people voted.
So we can say that;
Percentage of members voted can be calculated by dividing Number of members voted from The total number of members in the election and then multiplying by 100 we get;
Percentage of members voted =
Hence 30% members have voted.
Given:
The total distance from the apartment to the coffee shop = 9 miles.
Distance from the apartment to the park = 5x².
Distance from the park to the coffee shop = 25x - 8.
Assume that all three locations lie in a straight line.
Then
5x² + 25x - 8 = 9
5x² + 25x - 17 = 0
Solve with the quadratic formula.
x = (1/10)[ -25 +/- √(25²+340 )] = 0.6064 or -5.6064.
Reject the negative answer.
Therefore,
Distance from the apartment to the park = 5x² = 1.839 miles.
Distance from the park to the coffee shop = 25x - 8 = 7.16 miles.
Answer: x = 0.6064
Scalar multiplication of a matrix refers to the
multiplication of all the elements of the matrix by an ordinary number which is
called a scalar.
From the given options the statements which are true about
scalar multiplication of matrices are;
a)
You can
multiply a matrix of any size by a scalar.
b)
For any matrix A, 1 × A = A.
c)
Scalar multiplication is a shortcut for repeated
addition of the same matrix.
|x| - this means the absolute value of x, that is the distance from 0. It means that not matter what the value of x is, this value will be non-negaitive. So it will be the same for every value and for the negative number which has the corresponding negative value.
And the solutions to the equation above are: 3 and -3.
