Answer:
A) Check the first two: 2(x+5) and 2(x) + 2(5)
B) Check the last one: 14y + 2
The solution of (3,13) means you need to create two lines that satisfy x = 3 and y = 13
The two lines can be anything as long as they give this solution
For example, if you wrote x + y = 16 (you know their values already)
Then write another y - x = 10
From here you have your equations, turn them into the f(x) form.
x + y = 16 can be turned into y = 16 - x which is f(x)=16-x
y-x = 10 can be turned into y = 10 + x which is g(x)=10 + x
Answer:
<h2>New salary= $43,800.24</h2>
Step-by-step explanation:
Step one:
Given data
the initial salary is = $42,360
the raise in percentage is =3.4%
To know the raise we need to calculate what the amount of 3.4% of $42,360 is
Step two:
=(3.4/100)*42,360
=0.034*42360
=1440.24
therefore thr raise is $1440.24
Step three:
the new salary is given as
new salary= old salary+ raise
New salary= $42,360+$1440.24
New salary= $43,800.24
<em>48.25 in^2</em>
Step-by-step explanation:
The formula for the surface area of a pyramid is:
B represents the area of the base, which in this case is a triangle. We will figure out the area of the base first, using the formula for the area of a triangle.
A = 10.75
Now we can plug in 10.75 for B.
The cursive L will be the lateral height, which is 5. Since there are 3 sides on the base we can put that in for the number of base sides, and the base is 5.
