You first have to make an simple equation.
= How many pennies
= How many quarters
After that, since a penny is 5 Cents and a quarter is 25 Cents, we make the equation as:
(cents)
To write the whole entire thing in an equation is:

Since I brought the x from the left to right, we change the positive "
" to negative "
"
To bring the '
' to
, we get rid of the "
"s from both equations.
Now, you are left with the simplified equation:








Now you find the
.
= 28

Conclude:
So the y was the quarter and the x was the pennies.
Quarters = 13
Pennies = 28
Answer: Light waves
Step-by-step explanation:
Used in the usual sense, radiant energy is just light. When you turn on your electric stove unit, it heats up and emits radio waves, infrared waves, and visible light waves. All of these waves are just light with different frequencies.
To find the surface area of a prism<span> (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a</span>prism<span> (it doesn't matter if it is rectangular or triangular) we multiply the </span>area<span> of the base, called the base </span>area<span> B, by the height h</span>
Answer:

Step-by-step explanation:
y=mx+c
where m is the gradient and c is the y-intercept of the line
Let's find the gradient of the line first.

Using the above formula,

Subst. the gradient into m:

Now, find the value of c by substituting a coordinate into the above equation.
when x=-1, y=3,

Therefore the equation of the line is
