Answer:
f(5) = -2
Step-by-step explanation:
You look on the x-axis for 5 because f(5) means let x = 5. Then go down to the graph (the red zig-zaggy line) At the red line (you're still directly under the 5) look over to the y-axis to find the value. That's your answer. It is -2. The point (5, -2) is on the red graph.
f(5) = -2
Answer:
width = 19 inches
Step-by-step explanation:
Pythagorean theorem
23^2 = 13^2+x^2
529 = 169+x^2
x^2 = 360
x = 18.97
Answer:
x=5
Step-by-step explanation:
5x-2=23
add 2 to both sides
5x=25
divide by 5 on both sides
x=5
Because you ate multiplying big numbers, you know your answer is going to be even bigger...and 78 x 134= 10,452
