Answer:
use own words
Step-by-step explanation:
An expression is just a mathematical phrase. In this tutorial, you'll learn about two popular types of expressions: numerical and algebraic expressions. A numerical expression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables.
in mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)

The two numbers are 10 and 1. When you add 10 and 1, it adds up to 11. When you multiply 10 by 1, the answer is 10.
Hope it helps :)
Answer:
The perpendicular line would be y = -1/2x
Step-by-step explanation:
Perpendicular lines have opposite and reciprocal slopes. This means that we take the original slope (2) and negate it (-2). Now that we have the negated version, we need to flip it (-1/2).
With the slope of our new equation decided, we simply need to plug it along with the point into point-slope base form and then solve for y.
y - y1 = m(x - x1)
y + 4 = -1/2(x - 8)
y + 4 = -1/2x + 4
y = -1/2x
Answer:
33
Step-by-step explanation:
f(4) = 4(4) - 3 = 16 - 3 = 13
g(-5) = -2(-5) + 10 = 10 + 10 = 20
13 + 20 = 33
