Jeffrey works as a barista at a cafe. He earns tips plus an hourly wage of $8.50, both of which are included in his weekly paych
eck. After working for one week, Jeffrey received a paycheck for $410.50. If Jeffrey made $130 in tips that week, which equation could be used to determine, h, the number of hours Jeffrey worked during that week?

Answer:
The answer is 8.50h + 130 = 410.50
Step-by-step explanation:
For Plato users:
The total amount of Jeffrey's paycheck is equal to the amount he earns from his hourly wages plus the amount he earns from tips. The amount he makes from his hourly wages is 8.50h, which is the hourly wage times the number of hours, h, Jeffrey works each week. The amount earned from tips is $130. Set the sum of these two values equal to the total amount of Jeffrey's paycheck in order to complete the equation representing this situation.

Answer:
a) ∝A ∈ W
so by subspace, W is subspace of 3 × 3 matrix
b) therefore Basis of W is
={
}
Step-by-step explanation:
Given the data in the question;
W = { A| Air Skew symmetric matrix}
= {A | A = -A^T }
A ; O⁻ = -O⁻^T O⁻ : Zero mstrix
O⁻ ∈ W
now let A, B ∈ W
A = -A^T B = -B^T
(A+B)^T = A^T + B^T
= -A - B
- ( A + B )
⇒ A + B = -( A + B)^T
∴ A + B ∈ W.
∝ ∈ | R
(∝.A)^T = ∝A^T
= ∝( -A)
= -( ∝A)
(∝A) = -( ∝A)^T
∴ ∝A ∈ W
so by subspace, W is subspace of 3 × 3 matrix
A ∈ W
A = -AT
A =
=
therefore Basis of W is

Answer:
Step-by-step explanation:
Proportional relationship means,
x ∝ y
x = ky
where 'k' is the proportionality constant.
From table (1),
Therefore, relationship is not proportional.
From table (2),
True.
So the relationship will be proportional.
From table (3),
Which is constant.
Therefore, relationship will be proportional.
From table (4),
Which is constant for every term.
Therefore, relationship will be proportional.
