There is no solution to this, due to X can be equal anything. Hope this helps!
Answer:
see graph of y = 5x - 7
Step-by-step explanation:
If graphing is the task, you should rewrite the equation in a y = ax + b form. All straight lines can be described in this form, only the a and b determine which line it is.
Your equation 5x-y=7 has the 5x on the left side, so lets move it to the right. It will get a negative sign (this is the same as subtracting 5x like you did in your picture)
5x - y = 7
-y = 7 - 5x
Now we still have the -y which should be a +y. So we multiply left and right with -1 and get:
y = -7 + 5x
If we swap the -y and 5x (we can, because they are just an addition), we get:
y = 5x - 7
Now the equation is in its "normal" form. It's like the y = ax + b with a and b chosen as a=5 and b=-7.
The normal form is handy because you can immediately see the slope is 5 and the intersection with the y-axis is at y=-7.
Answer:
Aswer is 1.32
Step-by-step explanation:
1 divided by 0.85= x times y=1.32
Answer: 15.06
Step-by-step explanation:
Average points per game (mean) (m) = 22.5
Standard deviation (sd) = 6.2
Number of point scored in a game is 1.2 standard deviations below the mean, how many points below average was the value
1.2 standard deviations = (1.2 * value of standard deviation) = (1.2 × 6.2) = 7.44
Hence, 1.2 standard deviations below the mean equals :
Mean - 7.44
22.5 - 7.44 = 15.06
Hence, score = 15.06
Answer:
3
Step-by-step explanation:
The factor (x - 8) has 1 zero at x = 8
The factor (x + 3)² has a zero at x = - 3 of multiplicity 2
In total there are 3 zeros
