Answer:

False

Step-by-step explanation:

In order to perform matrix multiplication, the number of columns in the first matrix must be the same as the number of rows in the second matrix.

In this case, the number of columns in the first matrix is 5 and the number of rows in the second column is 3 therefore they aren't the same value, hence, cannot be multiplied

1) Miguel has a gift card to an electronics store. He has $ 150 on the card. He purchased a DVD for $ 20 and some games for $12.

GrogVix [38]

Answer:

9 games

Step-by-step explanation:

If he purchase 1 game, he spent $12.50. If he purchased 2 games, he spent 2(12.50) = $25.

This means he spent 12.5x for x number of games.

His total spending will be 12.5x + 20. He has $17.50 left on the card from $150.

150 - (12.5x + 20) = 17.5

150 - 12.5x -20 = 17.5

130 - 12.5x = 17.5

-12.5x = 17.5 - 130

-12.5x = -112.5

x = 9

Please help me struggling

Liula [17]

Answer:

Step-by-step explanation:

find the composition of g(x)=x−1 and h(x)= $\sqrt{x}$

hence we will get,

(g∘h)(x)=g(h(x))= g(x−1)= f(√x)= -1+√x = √x -1

Now to find f(g(h(x))),

f(x)=x4+6 and g(h(x))=√x -1

hence , putt g(h(x)) in f(x) ,

f(g(h(x)))= $(\sqrt{x}-1)^{4}$ +6 -
