8c+7d or 7d+8c
is the correct combination of terms
Answer:
C
Step-by-step explanation:
From the given coordinates
A(6, 0), B(0, 0) then AB = 6 - 0 = 6
B(0, 0), C(0, 8) then BC = 8 - 0 = 8
To calculate AC use Pythagoras' theorem on the right triangle formed
AC² = AB² + BC² = 6² + 8² = 36 + 64 = 100
Take the square root of both sides, hence
AC = = 10
Perimeter = AB + BC + AC = 6 + 8 + 10 = 24 → C
Answer:
f(4) = -11
If g(x) = 2 then x = 0
Step-by-step explanation:
here it asks to determine graphically, so we need to use the provided graph:
f(4) = -11 ( just notice the y-coordinate of the point of x-coordination 4)
If g(x) = 2 then x = 0 (just notice the x-coordinate of the point of y-coordination 2)
Answer:
Step-by-step explanation:
For example, let x, y and z be given variables. When we pair some variables, that means that we express the relationship between them. So, when we solve for a variable and it represents a <em>unique value</em>, that variable is called <em>a dependent variable.</em> Any remaining variables are called <em>independent variables. </em>For example, we will pair x and y and get
y = x + 8
Here, x is independent variable while y is dependent variable because its value depends on the value of x.
Now, we will pair all three variables on the following way :
y + z = x + 8 ⇒ x = 8 - y - z
Now, we have that x is dependent value because its value depends on the values of y and z.
