Answer:
400 students, 1/8 are left handed
Step-by-step explanation:
ANSWER
The scale factor is
EXPLANATION
The given triangle has vertices,
.
The vertices of the image triangle is,
.
The scale factor is given by
So we can use any of the corresponding sides to determine the scale factor,
Or
Or
The correct answer is C
For function one, the slope is already in mx+b form. The coefficient to x is the slope, so it is four in this case. For the second function we calculate the slope using rise over run. The rise is change in y and run is change in x, so 4/2= 2 slope. Four is greater than two so it has the greater rate of change. The answer is B
I just copied and pasted my previous answer as this is the same question I believe
Answer:
B (-9,−57/8)
Step-by-step explanation:
we know that
If a ordered pair is a solution of the linear equation, then the ordered pair must satisfy the linear equation
we have
<u><em>Verify each case</em></u>
Substitute the value of x and the value of y in the linear equation and then compare the results
case A) (6,17/2)
For x=6, y=17/2
Substitute
-----> is not true
therefore
The ordered pair not satisfy the equation
case B) (-9,-57/8)
For x=-9, y=-57/8
Substitute
-----> is true
therefore
The ordered pair satisfy the equation
case C) (6,-39/8)
For x=6, y=-39/8
Substitute
-----> is not true
therefore
The ordered pair not satisfy the equation
case D) (6,-8)
For x=6, y=-8
Substitute
-----> is not true
therefore
The ordered pair not satisfy the equation
Using the equation 2x + y = 4, we get the following graph.
