Expression consists of numbers, variables, and mathematical operations. The expression f(w)=5(w+4) is equal to f(9)=5(9)+20.
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The expression is given to you is,

Now, if we solve the expression it can be written as,

substituting the value of w, we will get,

Hence, the expression f(w)=5(w+4) is equal to f(9)=5(9)+20.

Answer: Our required values would be -10x+5, 2x+5 and -25.
Step-by-step explanation:
Since we have given that
g(x) = -4x+5
and
h(x) = 6x
We need to find (g-h)(x) and (g+h)(x).
So, (g-h)(x) is given by

and (g+h)(x) is given by

and (g-h)(3) is given by

Hence, our required values would be -10x+5, 2x+5 and -25.
Answer:
because there are 1000 grams in a kilogram then 1000 ÷ 10 is 100. so every bag weighs 100 grams
Answer:
Solve for y, graph it, and then find where the lines intersect.You can take a table and put in all the x and y values. Then graph it. And see where it intersects. Because usually, these equations are lines
Y=6 x is 3 and y is 6 the answer is 6 from the y axis
