Which matrix multiplication is defined ?
Answer:
A. CB
Step-by-step explanation:
3 x 2 (C is a 3 by 2) matrix can be multiplied to a 2 x 2 (B is a 2 by 2) matrix since C has 2 columns that are equal to the number of rows in the second matrix B.
A way of checking if two matrices can be multiplied is to first check the number of columns the first matrix contains and then check the number of rows that the second matrix contains.
If the number of columns in the first matrix equal the number of rows in the second matrix then that means it is possible to multiply these matrices.

x = frac{−1}{2}y + frac{45}{2}
Answer:
y- intercept = [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + [tex]\frac{4}{5}[/tex] ← is in slope- intercept form
with y- intercept c = [tex]\frac{4}{5}[/tex]

plz help. solve for x. i’ll give brainly
Answer:
x = 17.331....
Step-by-step explanation:
Basically use Tan on the calculator to find x. Look up "soh cah toa" if you still dont understand what I am doing.
Tan(37) = opposite / adjacent = x / 23
x = Tan(37) (23) multiply by 23 on both sides to get this
x = 0.753.... (23) now multiply the tan value on the calculator
x = 17.331....

find gcf
16x^2 -16+3
Answer:
13
Step-by-step explanation:
Step 1 to find gcf of 16x^2 -16+3 is factor out the equation = (4x)^2 -13 = (4x+13)(4x-13) So we factor to show one - and one + and then step 2 we then divide 4/4 -13/4 and 4/4 13/4 and cancel out 4/4 and see what we are left with = x>+ - 13/4 = 3 1/4 we can now find gcf by working out 16x^2 = 16(3 1/4)^2 = 16(10.5625) = 169 and the gcf of 169 and +- 13 = 13

Maria started her savings account with $105. she adds $10 to it each month, including the first month. Jana Rae started her account with $0 she adds $25 to it each month. after how many months will the girls have the same amount in their accounts? how much will they have?
Answer:
After 7 months, the girls will have the same amount in their accounts. They will have 175.
Step-by-step explanation:
Maria:
Starts with $105
Adds $10 each month
Jana Rae:
Starts with $0
Adds $25 each month
Set up an equation for both Maria and Jana.
m will represent the number of months.
Maria: 105 + 10m
Jana: 0 + 25m
You can do guess and check.
Let’s say m is equal to 6.
Subsitute m with 6 for both equations and check if they both end up having the same answer.
Maria: 105 + 10(6) = 165
Jana: 0 + 25(6) = 150
Is 165 and 150 equivalent? No
Let’s try m = 7 and do that same thing.
Maria: 105 + 10(7) = 175
Jana: 0 + 25(7) = 175
Now is the answer equal? Yes
So therefore, after 7 months, the girls will have the same amount in their accounts. They will have 175.

Help stuck on question number 10
Answer:
y = 2/3x - 5 or in standard form 3y = 2x - 5
Step-by-step explanation:
Remember this fact: Parallel lines have the same slope
Step 1 Solve for y so that the equation is in the slope- intersect form
2x - 3y = 6
-3y = -2x + 6
-3y/-3 = -2x/-3 + 6/-3
y = 2/3 x -2
now we know the slope is 2/3 or
when the equation is in Standard form Ax + By = C you can use this fact: slope = - A/B so the slope = -2/-3 = 2/3
Remember the Parallel lines have the same slope
Find the y-intersect "b" use the slope = 2/3 and point (6, -1)
y = mx + b
-1 = 2/3(6) + b
-1 = 4 + b
-5 = b
Now write the equation of line that is parallel to the given line and passes through point (6, -1)
y = 2/3x - 5 or in standard form 3y = 2x - 5

Answer:
x = 21
Step-by-step explanation:
35 + ?? = 7(5 + 3)
1. Expand the brackets on the right:
35 + x = 35 + 21
2. Cancel out 35 from both sides
x = 21
answer in comments pls!
Answer:
a)
2x/3 = 8. First, multiply both sides by 3 to make 2x = 24. Then, divide both sides by 2: x = 12.
b)
3x/2 = 6. First, multiply both sides by 2 to make 3x = 12. Then, divide both sides by 3: x = 4.
Hope this helps!
Answer:
A.) x = 12
B.) x = 4
Step-by-step explanation:
A.) 2x/3 = 8
First let’s multiply both sides by three to get rid of our division equation,
2x/3 = 8
*3 *3
2x = 24
Now we divide both sides by 2 to single out our variable,
2x = 24
/2 /2
X=12
Let’s check our answer just to be sure this is correct, we do this by plugging in “12” for our x
2(12)/3 = 8
24/3 = 8
8 = 8
Now we know that x = 12 is true,
B.)3x/2 = 6
Again well will multiply both sides by 2 to remove our division equation,
3x/2 = 6
*2 *2
3x = 12
We divide both sides by 3 to remove our coefficient in front of the variable,
3x = 12
/3 /3
x=4
Let’s check our answer once again,
3x/2 = 6
3(4)/2 = 6
12/2 = 6
6 = 6
X = 4 is true
How would I solve this? I believe it's two step, am I correct?
Answer:
[tex]b=0.8[/tex]
Step-by-step explanation:
1) Subtract 2.7 from both sides.
[tex]-5.3-2.7=-\frac{b}{0.1}[/tex]
2) Simplify -5.3 - 2.7 to 8.
[tex]-8=-\frac{b}{0.1}[/tex]
3) Multiply both sides by 0.1.
[tex]-8[/tex] × [tex]0.1=-b[/tex]
4) Simplify - 8 × 0.1 to - 0.8.
[tex]-0.8=-b[/tex]
5) Multiply both sides by -1.
[tex]0.8=b[/tex]
6) Switch sides.
[tex]b=0.8[/tex]
Answer:
b=0.8
Step-by-step explanation:
[tex]\frac{b}{0.1} = 8\\b= (0.1)(8)\\b=0.8[/tex]

how to make h the subject in
m= r - h + 4d
9514 1404 393
Answer:
h = r +4d -m
Step-by-step explanation:
There are a couple of ways to go about this:
1) Solve it the way you would any 2-step linear equation.
Step 1:
Identify the terms that do not involve h on the side of the equation that has the h-term. Subtract those terms from both sides of the equation.
m -r -4d = -h
Step 2:
If the coefficient of h is not 1, divide both sides of the equation by that coefficient.
(m -r -4d)/(-1) = (-h)/(-1)
-m +r +4d = h
I like to have the leading coefficient be positive, so I might write this as ...
h = 4d +r -m
__
2) The only h term has a -1 coefficient, so it can be given a coefficient of +1 by adding h to both sides of the equation.
h +m = r +4d
There is an unwanted m term with the h term, so subtract that from both sides of the equation.
h = r +4d -m
Answer:
h = 4d -m + r
Step-by-step explanation:
m = r-h +4d
h = 4d -m + r
we know when the real root is r = h-4d
the m+h = r+4d is step 1
then simply h-m = 4d-m + r is step 2
then h = 4d -m + r
