Answer:
x=0
Step-by-step explanation:
if
h(x)= -5x+3
h(x)= 3
then
-5x+3 = 3
solve for x
-5x=0
x=0
Terry is drawing isosceles triangles with side lengths a, b, and c such that
a = y − x
b = x + z
c = y − z
Where x, y, and z are positive integers and x + y + z < 10.
Find all the possible triples (a, b, c) that satisfy this.

Answer:
{2, 2, 2}, {2, 3, 3}, {2, 4, 4}, {3, 2, 3}, {3, 3, 2}, {3, 3, 4}, {3, 4, 3}, {4, 2, 4}, {4, 3, 3}, {4, 4, 2}, {5, 2, 5}, {6, 2, 6}
Step-by-step explanation:
The requirement that side lengths be greater than 0 means that ...
y > x > 0
y > z > 0
Then possible values for x and z are 1, 2, 3, and possible values for y are 3, 4, 5, 6, 7.
When we list the possibilities, and exclude those that do not give isosceles triangles, we find the values of {a, b, c} can be those listed above.

Raul opened a savings account with $4800. Each week, d, Raul pays the dog sitter $20 from his savings account. Write a function, f(d) , that is equal to the amount of money in the account after Raul pays the dog sitter each week.
Answer:
The function is: f(d)=4800-20d
Step-by-step explanation:
With the information provided, the function to calculate the amount of money in the account after Raul pays the dog sitter each week would be equal to the amount he used to open the savings account minus the result of multiplying the amount he pays the dog sitter each week for the number of weeks:
f(d)=4800-20d
According to this, the answer is that the function is: f(d)=4800-20d.
1 5/6 - 3/8 Can someone Plz help me this Math Problem??
Answer:
1 11/24
Step-by-step explanation:
1 5/6- 3/8
= (1-0) + ( 5/6 - 3/8)
= 1 + 5x4/6x4 - 3x3/8x3
= 1 + 20/24 - 9/24
= 1 + 20 - 9/24

Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100
Answer:
There are no solutions whenever k=4,5mod9.
This holds since it is not difficult to verify that for every integer n, we have n3=0,±1mod9.
Up till this year, there were just two values for k in the range 1..100 for which it was not known if there were a solution. These values are k=33,42.
Both values are now known to have solutions. See 42 is the answer to the question “

"This summer, the water level of Lake Conroe changed by a rate of -1.5 feet per month. The water level at the beginning of May was 187 feet above sea level. What was the water level at the end of four months?" heelpppp asaapp
Answer:
181 feets
Step-by-step explanation:
Given that:
Rate of change in water level = - 1.5 feets per month
Water level at beginning of May = 187 feets above sea level
Water level at the end of 4 months =?
Total change after four months = rate of change per month * number of months
= - 1.5 * 4 = - 6 feets
Hence water level after 4 months :
187 feets + (-6 feets)
187 feets - 6 feets
= 181 feets
Find the value of f(-9).
Answer:
f(- 9) = 2
Step-by-step explanation:
f(- 9) is asking for the value of y when x = - 9
Locate x = - 9 on the x- axis
Then go vertically up to meet the graph at (- 9, 2 )
Thus when x = - 9, y = 2 , that is
f(- 9) = 2

find the product if the sum of two numbers is 131 and the difference is 35
Please help: this is due in one hour. Please write let statements and equations.
Answer:
Step-by-step explanation:
let the two numbers be : x and y
x +y =131 , x-y= 35
by omitting :
x+y=135
x-y=35
cancel the ys with each other and add each side together
2x=135+35 = 170
to get x
x=170/2 =85
now u have the x time to get the y u can get it for any equation u like
85+y=135
y=135-85 = 50
the product = 85 x 50 = 4250

2. A farmer earns $4 for each bushel of corn he sells. The equation y = 4x can be used to
represent this situation, where x is the number of bushels of corn sold and y is the total amount
earned. What is the range that would represent this situation if no more than 1,000 bushels of
corn are sold?
Answer:
A
Step-by-step explanation:
Since x represents the bushels of corn that will be our variable. X (our number of bushels) is greater than or equal to zero, but x is less than or equal to 1000 since it is no greater than 1,000/

Samantha plays a trivia game. She earns 3 points for each
correct answer and loses 0.75 points for each incorrect
answer. She gets 11 correct answers and 4 incorrect
answers.
What is her score for the game?
Answer:
33/36
Step-by-step explanation:
take 0.75 x 4 = 3
then take
11 x 3 = 33
total score = 36
36 - 3 = 33
so the answer is 33/36
Answer:
Samantha would score 30 points
Step-by-step explanation:
If we multiply 11 x 3 we would get 33, the 11 represents the correct awnsers and the 3 represents the points
If we multiply 0.75 and 4 we get 3, this represents the incorrect
Next I subtracted 33 and 3 to get the answer of 30.
12. Using the equation y = -4(x + 2) give the:
a. x intercept
b. y intercept
Answer:
Step-by-step explanation:
y = -4(x + 2)
y = -4x + 2 *(-4)
y = -4x - 8
a) At x intercept, y= 0
-4x - 8 = 0
-4x = 8
x = 8/-4
x = (-2)
X intercept = -2
b) y- intercept = -8
