Step-by-step explanation:
To find the product of the matrices: ![\left[\begin{array}{cc}4&2\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D4%262%5C%5C%5Cend%7Barray%7D%5Cright%5D)
× ![\left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%265%5C%5C7%26-1%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Multiply rows of the first matrix by the columns of the second matrix.
(4 × (–2) + 2 × 7 4 × 5 + 2 × (–1))
After simplifying this, we get the product
Hence, × =

<h2>ask me in brainlist answer please </h2>
Start by finding out how much he sold on the two days. That will be;
Monday: 1/3 x 30= 10 cards
Tuesday: 3/2 x 30= 45 cards
From the above, you can see that he sold more than 30 cards on Tuesday. But less than 30 on Monday. So the correct answer is H.
He sold fewer cards than his goal on Monday and more cards than his goal on Tuesday. Hope I helped. Good luck
4/11 * 10/8
Multiplying fractions
1) multiply the numerators: 4 * 10 = 40
2) multiply the denominators: 11 * 8 = 88
3) simplify the fraction
40/88 ⇒ 10/22 ⇒ 5/11
40 ÷ 4 = 10
88 ÷ 4 = 22
10 ÷ 2 = 5
22 ÷ 2 = 11
4/11 * 10/8 = 5/11
Answer:
g(-3) = 23
Step-by-step explanation:
This question is telling us that x = -3. Knowing this, we can plug x into the equation and solve to find g(-3).
Square -3 to get 9
Multiply 9 by 3 to get 27
Subtract 4 from 27 to get 23
Thus, g(-3) is equal to 23.
I hope this helps! Good luck!
