Step-by-step explanation:
Matrices can be multiplied together if the number of columns in the first matrix equals the number of rows in the second matrix.
A is of order (3 × 2) and B of order (2 × 3 )
Since the 2 in the first and the 2 in the second match , the matrices can be multiplied
The resulting matrix is of order (3 × 3 )
This is obtained from the first 3 in order of A and the second 3 in order of B
Then AB is defined and the resultant matrix is of order 3 × 3

Micheala pays her cell phone service provider $19.95 per month for her service plan and 15 cents per minute. In June, her phone bill is $127.95. How many minutes did micheala use in June
Answer:
720 minutes
Step-by-step explanation:
Total phone bill = $127.95
Service plan fee = $19.95
Total cost per minute = 127.95 - 19.95
= $108.00
No. of minutes used = Total cost per minute / Rate per minute
= 108.00 / 0.15
= 720 minutes

The width of a rectangle measures (3c-9d)(3c−9d) centimeters, and its length measures (8c-2d)(8c−2d) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
HELP
-22d + 22c
Step-by-step explanation:
The expression for the perimeter of the rectangle is 2(11c - 11d)
Perimeter of a rectangle = 2(length + width)
Length = 3c - 9d
Length = 3c - 9d Width = 8c - 2d
The expression for the perimeter can be expressed thus :
2(3c - 9d + 8c - 2d)
Collect like terms :
2(3c + 8c - 9d - 2d)
2(11c - 11d)
Hence, the expression for the perimeter of the rectangle is 2(11c - 11d)

Please respond asap
Answer:
[tex]1 \frac{5}{8}[/tex]
Step-by-step explanation:
To figure out this problem we need to divide 6 1/2 by 4.
Convert any mixed numbers to fractions. Then your initial equation becomes:
[tex]\frac{13}{2} \div \frac{4}{1}[/tex]
Applying the fractions formula for division:
[tex]= \frac{13 \times 1}{2 \times 4}[/tex]
[tex]= \frac{13}{8}[/tex]
Simplifying 13/8, the answer is:
[tex]= 1 \frac{5}{8}[/tex]
In one baseball season, Peter hit twice the difference of the
number of home runs Alice hit and 6. Altogether, they hit
18 home runs. How many home runs did each player hit
that season?
Answer:
Alice hit 10 home runs.
Peter hit 8 home runs.
Step-by-step explanation:
Let [tex]p[/tex] be the number of home runs Peter hit.
Let [tex]a[/tex] be the number of home runs Alice hit.
[tex]p=2(a-6)\\a+p=18\\\\a+2(a-6)=18\\a+2a-12=18\\a+2a=30\\3a=30\\a=10\\\\a+p=18\\10+p=18\\p=8\\\\p=2(a-6)\\8=2(10-6)\\8=2(4)\\8=8[/tex]
what is the Domain of this?
Answer: The domain is 3/7, -6, and 4.
Step-by-step explanation:
In the case of rational expressions, we can input any value except for those that make the denominator equal to 0 (since division by 0 is undefined). In other words, the domain of a rational expression includes all real numbers except for those that make its denominator zero.
As the other answer mentioned, x = -6 and x = 4 are not in the domain, since they both make the denominator equal to zero, and thus the overall expression undefined. But x = 3/7 is allowed, since f (3/7) = 0.
Every other real number is also acceptable.
In interval notation, the domain is then
[tex](-\infty,-6) \cup (-6,4) \cup (4, \infty)[/tex]
-5x-4y=-8 Write a formula for f(X) in terms of x
hope its helps l got it from https://www.cymath.com/ its good for math solving.
Answer:
f(x) = - [tex]\frac{5}{4}[/tex] x + 2
Step-by-step explanation:
Note that y = f(x)
Rearrange making y the subject
- 5x - 4y = - 8 ( add 5x to both sides )
- 4y = 5x - 8 ( divide terms by - 4 )
y = - [tex]\frac{5}{4}[/tex] x + 2 , that is
f(x) = - [tex]\frac{5}{4}[/tex] x + 2

C -24, -18, -12, -20
D -24, -20, -18, -12
Answer:
D
Step-by-step explanation:
its not a because 12 is the greatest because its closest to zero
it not b because 24 is farthest from zero not 20
and its not c because 12 goes after 20 not 12,20

Solve for X. Show your work
1/2x - 1/4 = 3/5x + 2
Answer:
[tex]x = - \frac{45}{2} [/tex]
Step-by-step explanation:
[tex] \frac{1}{2} x - \frac{1}{4} = \frac{3}{5} x + 2[/tex]
[tex]20( \frac{1}{2} x - \frac{1}{4} ) = 20( \frac{3}{5} x + 2)[/tex]
[tex]20 \times \frac{1}{2} x - 20 \times \frac{1}{4} = 20( \frac{3}{5} x + 2)[/tex]
[tex]10x - 20 \times \frac{1}{4} = 20 \times \frac{3}{5} x + 20 \times 2[/tex]
[tex]10x - 5 = 20 \times \frac{3}{5} x + 20 \times 2[/tex]
[tex]10x - 5 = 4 \times 3x + 20 \times 2[/tex]
[tex]10x - 5 = 4 \times 3x + 40[/tex]
[tex]10x - 5 - 12x = 40[/tex]
[tex]10x - 12x = 40 + 5[/tex]
[tex] - 2x = 40 - 5[/tex]
[tex] - 2x = 45[/tex]
[tex]x = - \frac{45}{2} [/tex]

Honors algebra!! Plz help #22
Answer:

Step-by-step explanation:
12 times x (the first square) is equal to 16 times x-2 (the second square)
[tex]12x = 16(x-2)[/tex]
Distributed
[tex]12x = 16x-32[/tex]
Simplified (divided by 16)
[tex]0.75x = x-2[/tex]
Subtract x from both side of the equation
[tex]-0.25x = -2[/tex]
Both negatives cancel each other out
[tex]0.25x = 2[/tex]
0.25 times what equals 2,...

Evaluate the limit of sequence at infinity.
[tex] \displaystyle \large{ \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} }[/tex]
Please show your work too. Thanks!
Answer:
[tex]\displaystyle \frac{ 1 }{3} [/tex]
Step-by-step explanation:
we would like to compute the following limit:
[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} [/tex]
if we compute the limit from numerator to denominator directly,we'd end up with
[tex] \dfrac{ \infty }{ \infty } [/tex]
which is an indeterminate form so we must do it in a different way. well to compute this limit,we can consider factoring method . notice that we can factor the numerator and that yields
[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{ {n}^{2} ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]
remember that ,
[tex] \sqrt{ab} \implies \sqrt{a} \sqrt{b} [/tex]thus we acquire:
[tex]\displaystyle \lim_{n \to \infty } \frac{ {n} \sqrt{ ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]
reduce fraction:
[tex]\displaystyle \lim_{n \to \infty } \frac{ {} \sqrt{ 4 {}^{} + \frac{3}{n} } }{6} [/tex]
as n approaches to ∞ ,3/n approaches to 0 which yields:
[tex]\displaystyle \frac{ \sqrt{ 4 {}^{} } }{6} [/tex]
simplify square root:
[tex]\displaystyle \frac{ 2 }{6} [/tex]
reduce fraction:
[tex]\displaystyle \frac{ 1 }{3} [/tex]
hence,
[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} = \boxed{ \frac{1}{3} }[/tex]
and we're done!
