Answer:
A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.
Step-by-step explanation:
Given


Required
A good first step
A good first step is to eliminate x and this is done as follows:
Multiply
by 2 (gotten from coefficient of x in the second equation)
Multiply
by 3 (gotten from coefficient of x in the first equation)
This gives:


Add both equations



<em>Hence (a), is true</em>
Lines f and g look to be parallel to each other.
Answer:
89.008
Step-by-step explanation:
z = (x– mean)/ standard deviation
x = z * standard deviation + mean
Now, z value for the top 4% of the exams (which is the same as getting a score below the 96%) has to be found using a z table.
In this case z = 1.751
x = 1.751 * 8 + 75
x = 89.008
Answer:
here's the website ans the answers
Step-by-step explanation:
yes its positive and the slope is well I don't know sorry pls give me credit tho :((
Answer:
slope is -4/3 and y-int is -1
Step-by-step explanation:
Solve for y
3y = -3 - 4x
y = -4x/3 - 1
so the slope is -4/3
the y intercept is -1
Start by making a point at (0,-1), then count 4 down and 3 to the right and make another point. Continue to do this until you have a line long enough.
