Answer: 25 students per teacher and 12 students per tutor. They need 2.4 tutors for the school
To find two numbers that multiply to 18 and add to -5, consider the factors of 18 and check which pair meets the conditions. The numbers that satisfy the given conditions are -9 and -2.
To find two numbers that multiply to 18 and add to -5, we can use the factoring method. By considering all the possible factors of 18, we can find the pair of numbers that satisfy the given conditions. The two numbers that meet these criteria are -9 and -2.(-9 * -2 = 18, -9 + -2 = -11)

Step-by-step explanation:
Answer:
5
Step-by-step explanation:
When subtracting a negative number, you will add it.
This is because the negative signs of the subtraction sign and the negative number will cancel out.
This will change the subtraction sign to a positive sign and will switch the negative sign on the number to a positive one.
So, 3 - (-2) will change to 3 + (2)
3 + 2
= 5
(0, 1) and (1, 1)
(0, 0) and (1, 1)
no solutions
Answer:
Step-by-step explanation:
we have
-------> equation A
-------> equation B
we know that
The solution of the system of equations is the intersection points both graphs
using a graphing tool
see the attached figure
The intersection both graphs is the point
therefore
the solution is the point
Well, from the info given, you cannot automatically put it into slope intercept form. You have to put it into point slope form first and then convert it.
Point slope form looks like this: y - y1 = m(x - x1)
Now, with the info it looks like this: y - (-2) = -3(x - 1)
Now you distribute and change the - (-2) to +2 (because subtracting a negative is the same as adding a positive) and you get: y + 2 = -3x - 3
Now, you subtract 2 to get y by itself (we are converting now)
y = -3x - 5
Hope this helps!
Answer:
y = x + 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given the equation of line L₁
y = - 3x + 8 ← in slope- intercept form
with slope m = - 3
given a line with slope m then the slope of a line perpendicular to it is
= - = - ( ) = , then
y = x + c ← is the partial equation of line L₂
to find c , substitute the point P(3, 5 ) into the partial equation
5 = (3) + c = 1 + c ( subtract 1 from both sides )
4 = c
y = x + 4 ← equation of line L₂
