in order to solve these equations, you need to divide the number by the varible. so #5 is 2.5y=5. you would divide 5 by 2.5, to get 2. the answer would be y=2

Answer: D; 3 - 7 = -4

Explanation: Since 3 is the largest value in this equation and the arrow is going to the left (starting at a positive and stopping at a negative), you count backwards 7, which would be subtracting 3 from 7 in this case.

Need help pleaseeeee

Answer: cools rapidly

Step-by-step explanation:

Some igneous rocks contain crystals of very different sizes. These

rocks formed from magma that started cooling within Earth and then

erupted onto the surface. The large crystals grew as the magma cooled

slowly. The small crystals grew as the lava cooled quickly.

Hope this helps!

A tower is 200 ft tall to the nearest degree find the angle of elevation from a point of 50 feet from the base of the tower to t

Elodia [21]

Answer:

Step-by-step explanation:

What you have here is classic right triangle trig. The height of the tower is the height of a right triangle, and the point 50 feet from the base of the tower is the base of the triangle. The angle of elevation is the base angle that is NOT the right angle. The height is opposite the base angle, while the base is adjacent to the angle, so we need the tangent ratio to find the angle. Here's what we have:

$tan(\theta)=\frac{200}{50}$

When you are looking for a missing angle, you use the inverse of the angle on your calculator. To do this, hit the 2nd button, then tan, and what you see on your screen is

$tan^{-1}($

Enter 200/50 (or 4) and hit "enter" to find the missing angle. It comes out to 75.9 so 76 degrees.

Which graphs below represent an exponential function? Select all that apply.

Troyanec [42]

The two graphs in the second picture are the graphs of exponential functions. You can detect it from the L shaped graphs.

The very first graph represents a linear function. A straight line always represents a linear function. In a Linear function, the change in the values of y is constant throughout in relative to change in x values.

The final graph represents a quadratic function rising on both ends.

Therefore, option b and c are the correct answers
