<h3>Answer: Yes it is possible</h3>

Explanation:

Any linear equation in the form y = mx+b has a constant rate of change, and that rate of change is the slope m. If b = 0, then it turns into y = mx. Here m is the constant of proportionality. Direct proportion equations always go through the origin. If b is nonzero, then y = mx+b will not be proportional.

So for example, y = 2x is proportional while y = 2x+1 is not proportional.

Interior angles of a square always sum to 360°. A reflection in the x-axis would not change this.

Answer:

1. a. 3xy²(7x²y³ + 5x - 4y)

2. a. (3x + 2)(5x + y)

3. d. (2a + b)(5x - 4)

Step-by-step explanation:

For #1, your answer was missing an exponent, which I boldfaced. Every term has a <em>y</em><em>²</em><em> </em>in common. Then, in numbers 2 and 3, just factor each group one at a time.

Ex: [10ax + 5bx] - [8ay - 4by]

A stick 1 meter long casts a shadow 0.6 meters long. A building casts a shadow 25 meters long. How tall is the building (to 2 de

zloy xaker [14]

Answer:

41.67

Step-by-step explanation:

Using the tangent on the stick with shadow:

tan(θ) = $\frac{1}{0.6}$

Using the tangent on the building:

tan(θ) = $\frac{h}{25}$

⇒ h = 25 · tan(θ)

= 25 · $\frac{1}{0.6}$

⇒ h = 41.66... ≈ 41.67

You and your family go out to dinner to build a total of $54 plan to leave 20% tip how much tip should you leave

loris [4]

Answer:

$10.8 is left.

Step-by-step explanation:

Given that,

Total amount = $54

Left amount = 20%

We need to find how much tip should you leave. It means we need to find 20% of 54. So,

$A=\dfrac{20}{100}\times 54\\\\=\$10.8$

So, $10.8 is left.
