Answer:
2. correct
3. addition property of equality
4. substitution property of equality
Step-by-step explanation:
You're asked for the Reasons, so you need to examine the Statements to see how you get from one line to the next.
The first line of Statement 2 differs from Statement 3 in that m∠GHI has been added to both sides of the equation (ignoring the typo in statement 3). The reason you can add the same thing to both sides of an equation is given by the <em>Addition Property of Equality</em>.
Statement 3 differs from Statement 4 in that one of the m∠GHI has been replaced by m∠JKL. We can do this replacement because those measures are equal to each other. Replacement of equals by equals is allowed by the <em>Substitution Property of Equality</em>.
No, they're not equivalent
16/9 is the answer, just use a calculator next time or multiple 4/3 x 4/3
A Domain is the lowest and highest x value (-5,-2) is how it is formatted this means -5 to -2
Range is the lowest to highest Y value so (-3,3)
(-5,-2) - domain
(-3,3) - range
B Intercept are when the line crosses the acis labeled x so
(-2,0) and (2,0)
C F(1) means what is x when y is equal to 1 so we must estimate this
(-1,1) and (1.5,1)
D f(x) = -3 is when y is -3 so we look at the graph to see
-5 and 4 are the values for x
E f(x) < 0 means when y is above the x axis
This is between the x values of -2 and 2 or (-2,2)
The equation of the lines can be plotted on the graph after calculating the coordinates on each line.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have two linear equation:
x = 4y
x + y = 7.0
To plot the linear equation first we will find the few coordinates to plot on the coordinate plane.
For the equation of line:
x = 4y
x 0 1 2 3 -1 -2 -3
y 0 4 8 12 -4 -8 -12
For the equation of line:
x + y = 7.0
x 0 1 2 3 -1 -2 -3
y 7 6 5 4 8 9 10
Thus, the equation of the lines can be plotted on the graph after calculating the coordinates on each line.
