Answer:
72
Step-by-step explanation:
Answer:
The slope is -5/6
Step-by-step explanation:
To find the slope of a line given two points, we use the formula
m= (y2-y1)/(x2-x1)
= (-1-4)/(4--2)
=-5/(4+2)
=-5/6
Answer:
No, Angela is not correct.
As the method Jim was performing will also lead to the solution.
Step-by-step explanation:
We are given first equation as:
Ax + By = C
Second equation is:
Dx + Ey = F
Jim solved the equation as:
He begins by multiplying equation (1) by D and equation (2) by A.
and so by subtracting both the equations he will obtain a value of y.
and then put the y-value in any of the given two equations to obtain the value of x.
Angela Method:
you should have multiplied equation (1) by E and equation (2) by B.
and when she will subtract both the equations she will get the value of x first and then when she will put the value of x in any of the given equation she will obtain the value of y.
But both will get a value for x and y.
Hence, the method Jim was performing was also correct.
B
If he can type 1/3 as many words as her that would be 1/3j which is the same as j/3.
