Answer:
There are 9 possible isosceles triangles
Step-by-step explanation:
Inequalities
Let's consider an isosceles triangle with equal side lengths x and unequal side y.
The perimeter of that triangle is:
P = x + x + y =2x + y
The perimeter has a fixed value of 20 units, thus:
2x + y = 20
Solving for y:
y = 20 - 2x
The solutions of this equation have two restrictions:
* Both x and y must be positive
* Both x and y are integer (whole) numbers.
The first restriction leads to inequality:
20 - 2x > 0
Solving for x:
x < 10
Since x must also be positive, only the following numbers are valid solutions for x: {1,2,3,4,5,6,7,8,9}
There are 9 solutions for x, giving this set of 9 solutions for y: {18,16,14,12,10,8,6,4,2}
Thus, there are 9 possible isosceles triangles

The solution set is {-7, 7}.
Step-by-step explanation:
He was half right .There are 2 solution d = -7 and d = 7.
A moving company’s moving rates can be represented by the function f(x) = 3x + 400, where x is the number of miles for the move.
Another moving company’s rates can be represented by the function g(x) = 5x + 200.
Which function represents the difference between the moving companies' rates, h(x) = f(x) – g(x)?
A) h(x) = 2x + 200
B) h(x) = –2x + 200
C) h(x) = 5x – 200
D) h(x) = 5x + 600
Answer:
B) h(x) = –2x + 200
Step-by-step explanation:
f(x) = 3x + 400
g(x) = 5x + 200
f(x) - g(x) = 3x + 400 - (5x + 200) = -2x + 200

WORTH 50 POINTS NEED HELP ASAP
Answer:
-10, -1, 5
Step-by-step explanation:
To find the zeros of a function, you have to set each factor to zero in equations, then solve for x ....
x + 10 = 0 ... then factor 10 over (subtract 10 from each side) ...
x = -10
x-5=0
then repeat (add 5 to both sides) (and subtract 1 from both sides) ...
x -5 = 0 to x = 5
x + 1 = 0 to x = -1

One electrician charges a $50 service call fee plus $25 per hour for labor. Another electrician charges a $35 service call fee plus $27.50 per
hour for labor. How long would a job take if the total cost for each electrician is the same?
A.5 hours
B.6hours
C.7 hours
D.8 hours
Answer:
c. 6 hour
Step-by-step explanation:
time = t
25t + 50 = 27.50t + 35
solve for t : 25t + 50 = 27.5t +35
27.5t + 35 = (55t) /2 + 35 : 25t + 50 = (55t) /2 + 35
subtract (55t) /2 + 50 from bot side : -(5t) /2 = -15
multiply both side by -2/5: t = 6 hours
