Step-by-step explanation:
Step 1: Define Equation
-w - 2 = 42
Step 2: Solve for w
Add 2 to both sides: -w = 44Divide -1 on both sides: w = -44Step 3: Check
Plug in w into the original equation to verify it's a solution.
Substitute in w: -(-44) - 2 = 42Multiply: 44 - 2 = 42Subtract: 42 = 42Here we see that 42 does indeed equal 42.
∴ w = -44 is the solution to the equation.

Answer:
Step-by-step explanation:
first just look at the graph
its very obvious its a linear graph because it is going up in a straight line at a steady pace
so we can then just ignore the answers that say its not a linear function
then since its straight and not curved (curved graphs or parabolas are found when x has an exponent) its obvious it cant be one of the equations with x^2
so we are left with one the final answer
its equation is y = x + 2 and it is a linear function
hope this helps <3

A doctor orders 2000 units of subcutaneous heparin to be administered to a patient, The label is 5000 units/ml. How many milliliters will be
administered?
Answer:
0.4 mL
Step-by-step explanation:
I was able to do this in my head, but...
If you just take the fraction of 2000 units/5000 units/mL, then the units will cancel out and you're essentially left with 2000/5000 mL. 2000/5000 can be reduced to 2/5, and as a decimal, 2/5 comes out to 0.4 or 40%.
So, 0.4 mL (about half) would be administered to the patient.
what is a domain and range
and how do I find it
Answer: Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
A motorboat moves across a lake at a constant speed. When it begins, it is 48
km from the shore. After 10 minutes, it is 18 km from the shore. Which
function describes the motorboat's distance from the shore?
O A. y = 10x+48
B. y=-3x + 48
O c. y=-10x + 48
O D. y = 3x + 48
Answer:
b
Step-by-step explanation:
The function describes the motorboat's distance from the shore is y=-3x + 48. So, the correct option is B.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, a motorboat moves across a lake at a constant speed.
Let x be the number of minutes and y be the total distance.
When it begins, it is 48 km from the shore.
Now, (x₁, y₁) =(0, 48)
After 10 minutes, it is 18 km from the shore.
So, (x₂, y₂) =(10, 18)
We know that, Slope(m) =(y₂-y₁)/(x₂-x₁)
= (18-48)/(10-0)
= -30/10
= -3
Substitute, (x, y)=(0, 48) and m=-3 in y=mx+c, we get
48=-3(0)+c
c=48
Substitute, c=48 and m=-3 in y=mx+c, we get
y=-3x+48
Therefore, option B is the correct answer.

We want to find all the solutions to the equation [tex]f(x)=0[/tex]. Wich means that we want to find all values of [tex]x[/tex] such that [tex]y=0[/tex] (recall f(x)=y).
By looking at the graph, when does [tex]y=0[/tex]? That's right, exactly over the X axis!
The solutions to the equation are the X coordinates where the graph crosses the X axis.
They are -5,-2 and 4.
Select all the equations below that have a slope of -5.
