Answer:

Factor the expression

- 45x + 40 \\  =  - 5(9x + 8)

Expand the expression

4w + 9( - 6 - 3w) \\ 4w - 54 - 27w \\ =   - 23w - 54

hope this helps

Answer:

\large \boxed{\mathrm{view \ explanation}}

Step-by-step explanation:

-45x + 40

Factor out 5 from the expression.

5(-9x) + 5(8)

Take 5 as a common factor.

<u>5(-9x + 8)</u>

4w + 9( -6 - 3w)

Expand brackets.

4w + 9(-6) + 9(-3w)

4w - 54 - 27w

Combine like terms.

4w - 27w - 54

<u>-23w - 54</u>

A DVD was priced at $2.87 last week. This week the same DVD is priced at $10.59. What is the percent increase in price?
solniwko [45]

Answer:

Percentage increase = 269%

Step-by-step explanation:

Price of a DVD last week = $2.87

Price of the same DVD this week = $10.59

Increase in the price of DVD between last week and this week = 10.59 - 2.87

= $7.72

Therefore, percentage increase in the price of DVD = \frac{\text{Increase in the price}}{\text{Price of DVD last week}}\times 100

= \frac{7.72}{2.87}\times 100

= 268.99

= 269%

Step-by-step explanation:

First question:

You are given a side, a, and its opposite angle, A. You are also given side b. Use that in the law of sines and solve for the other angle, B.

\dfrac{a}{\sin A} = \dfrac{b}{\sin B}

\dfrac{10}{\sin 30^\circ} = \dfrac{40}{\sin B}

\dfrac{1}{0.5} = \dfrac{4}{\sin B}

\sin B = 2

The sine function can never equal 2, so there is no triangle in this case.

Answer: no triangle

Second question:

You are given a side, b, and its opposite angle, B. You are also given side c. Use that in the law of sines and solve for the other angle, C.

\dfrac{b}{\sin B} = \dfrac{c}{\sin C}

\dfrac{10}{\sin 63^\circ} = \dfrac{}{\sin C}

\sin C = \dfrac{8.9\sin 63^\circ}{10}

C = \sin^{-1} \dfrac{8.9\sin 63^\circ}{10}

C \approx 52.5^\circ

One triangle exists for sure. Now we see if there is a second one.

Now we look at the supplement of angle C.

m<C = 52.5°

supplement of angle C: m<C' = 180° - 52.5° = 127.5°

We add the measures of angles B and the supplement of angle C:

m<B + m<C' = 63° + 127.5° = 190.5°

Since the sum of the measures of these two angles is already more than 180°, the supplement of angle C cannot be an angle of the triangle.

Answer: one triangle

HELP ITS URGENT please

The correct answer is D.

A function cannot have an x-value that corresponds to more than one y-value.
In this table, the x-value '8' corresponds to two separate y-values; 8 and 5, making it invalid as a function.
