Step-by-step explanation:
<u>Evaluating Algebraic Expressions</u>
Given an expression where variables (letters) are included, evaluate the expression at specific values of the variables means to substitute the values into the expression, operate, and give the final result.
The expression provided in the question is:
4m + 3
Evaluate at m=5
Substitute m for 5 recalling 4m really means 4*m, a product:
4*5 + 3 = 20 + 3 =23
Answer:
P(A and B) = 0.2
Step-by-step explanation:
P(A and B) = P(A) * P(B) = 0.5 * 0.4 = 0.2
The answer is $15, you add them all and divide by 10
3 pounds would cost $6.75
$4.50/2 = $2.25 per pound
$2.25 x 3 = $6.75
y = 1 - 3x goes to slope -3, y-intercept at 1
x - 3 = y goes to slope 1, y-intercept at -3
y = 3x - 1 goes to slope 3, y-intercept at -1
-x + 3 = y goes to slope -1, y-intercept at 3
