Answer:
b is 7 units from 0.
Step-by-step explanation:
= 7 means that the absolute value of b is 7. This means that b can be -7 or 7, so it will always be 7 units from 0.
Hope this helps!
Answer:
Y=1/3x-1 is the correct answer in slope intercept form:)
Hopefully! this help.
Step-by-step explanation:
Hello!
To solve this, you are trying to convert one side to a quadratic equation and the other to just 0. Then, solve the equation.
----
First, move the /2 to the other side of the equation.
(a+1)/2 = 1/a
a+1 = 2/a
Next, multiply both sides by a.
a+1 = 2/a
And then subtract both sides by 2. This will get you to a quadratic equation.
Now, factor the equation. When we're factoring, we are looking for the form (a + b)(a + c), where b + c must equal 1 (the coefficient of a) and b*c must equal -2. In this case, b = 2, and c = -1.
Therefore:
(a + 2)(a - 1) = 0
To get the answer, recall that anything multiplied by 0 is equal to 0. Therefore, to get the left side to equal 0, either (a + 2) or (a - 1) must equal 0. To do this, a must either be -2 or 1.
Therefore, a = -2, or a = 1.
----
Check your work:
(-2 + 1)/2 = 1/-2
-1/2 = -1/2
(1 + 1)/2 = 1/1
2/2 = 1/1
1 = 1

Hope this helps!
Answer:
300 students
Step-by-step explanation:
If 195 students is 65%, then we can divide 195 by 65 to find what 1% is.
195/65= 3
So 1% of the 8th grade class is 3 students. We want to know how many students are in the whole class, which would be 100% of the class.
If we multiply the 3 (which is 1%) by 100 (to get 100%) we can find the total number of students.
3x100=300
We can check this by finding 65% of 300, and seeing if that is 195.
300x.65=195
It does check out.
