The statement written as a simplified mathematical expression is -18x
<h3>Writing mathematical expression</h3>
From the question, we are to write the given statement as a mathematical expression
The given expression is,
"<em>Nine times the product of a negative two and a number</em>"
Let the number be x
Thus,
The product of negative 2 and a number means
-2 × x = -2x
Then,
Nine times the product of a negative two and a number is
9 × -2x = -18x
Hence, the statement written as a simplified mathematical expression is -18x

Since you know the value of x, you can substitute/plug it into the equation to find the value of y:
y = 2x + 5 Plug in 1 into "x" since x = 1
y = 2(1) + 5
y = 7
When x = 1, y = 7 --> (x, y) = (1, 7) Your answer is #4
Answer:
Look below.
Step-by-step explanation:
Good ol' Pythagorean Theorem.
To find the short side of the larger triangle, we'll use this equation:
You can solve the rest on your own.
Use the same type of equation for the smaller triangle, except your b would be the hypotenuse, so that equation would look something like this:
