you have negative -12
turn this into a positive (12)
12 plus 18
= 30
Answer:
Step-by-step explanation:
Domain : Set of all possible input values (x-values) on a graph
Codomain : Set of all possible out values for the input values (y-values) on the graph
Range : Actual output values for the input values (x-values) given on the graph.
Therefore, for the given graph,
Domain : (-∞, ∞)
Codomain : (-∞, 2]
Range : (-∞, 2]
From the given graph every input value there is a image or output value.
Therefore, the given function is onto.
Answer:
y = 0.1x - 4
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (-3, 7)
Points on the y-axis (y1, y2) = (-7, -6)
First of all, we would find the slope;
Mathematically, slope is given by the formula;
Substituting into the equation, we have;
Slope = (-6 - (-7))/(7 - (-3))
Slope = (-6 + 7)/(7 + 3)
Slope = 1/10
Slope = 0.1
Next, we would write the equation using the formula;
y - y1 = m(x - x1)
y - (-7) = 0.1(x - (-3))
y + 7 = 0.1(x + 3)
y + 7 = 0.1x + 3
y = 0.1x + 3 - 7
y = 0.1x - 4
<u>Answer:</u>
<h2><u>-2.25</u></h2><h3>
<u>Step-by-step explanation:</u></h3>
Lets start with D:
It says, 0.43 but we're on the OPPOSITE of 0, so it can't be a positive number.
Same goes for C.
Now we are on to our last two.
B, is -2.5 and A, is -0.8
So, now we look at the point <em>B </em>and <em>assume</em>, because it says Select a reasonable value for Point B.
To me, point <em>B </em>looks to be about around -2.0
So, the <em>reasonable value </em>for this problem would be -2.25
Really
just calculate the slope
slope is (y2-y1)/(x2-x1)
for x=0, y=1
for x=1, y=3
slope=(y1-y1)/(x-x1)=(3-1)/(1-0)=2/1=2
answer is 2
