Answer:
x=10
Step-by-step explanation:
first substitute y with the value (-5)
2x+5(-5)=-5 which is simplified to 2x+-25=-5
add 25 to -5 which gives you 2x=20
then divide 20 by 2 which makes x=10

Liam has a bag of b beads. He gives 20 beads to his sister. He then makes 4 necklaces with the same of beads on each necklace using all of the remaining beads. Write an expression that represents the number of beads on each necklace. Show your work.
Given :
Liam has a bag of b beads.
He gives 20 beads to his sister.
He then makes 4 necklaces with the same of beads on each necklace using all of the remaining beads.
To Find :
Write an expression that represents the number of beads on each necklace.
Solution :
Number of necklace remains after giving 20 beads to his sister is ( b - 20 ).
Number of beads on each necklace using all of the remaining beads is :
[tex]N=\dfrac{b-20}{4}[/tex]
Hence, this is the required solution.
A line passes through the points (P, a) and (P, –a) where P and A are real numbers and P does not equal 0. Describe each of the following. Explain your reasoning.
1. slope of the line
2. equation of the line
3. y-intercept
4. slope of a line perpendicular to the given line
9514 1404 393
Answer:
undefinedx = Pdoes not exist0Step-by-step explanation:
2. The x-value of the given points is the same, so the points both lie on the vertical line ...
x = P
__
1. The slope of a vertical line is "undefined".
__
3. Given that P ≠ 0, the vertical line is parallel to the y-axis, so there is no y-intercept.
__
4. A line perpendicular to a vertical line will be horizontal. A horizontal line has a slope equal to zero.

What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
Given the function defined by y = x^2
now,
its average rate of change from x = 2 to x = 10,=
=10^2-2^2/10-2
=100-4/8

Skyler is buying wings and quesadillas for a party. A package of wings costs $8.00. A package of quesadillas cost $10.00. He must spend no more than $160.00. Skyler's freezer will hold a maximum of 20 packages of wings and quesadillas. Write a system of linear inequalities to represent the situation.
Answer:
The system of inequalities are;
q + w ≤ 20
8w + 10q ≤ 160
Step-by-step explanation:
Let the number of wigs be w and the number of quesadillas be q
Since we have a maximum of 20 packages;
then;
q + w ≤ 20
Let’s now work with the prices
price of w wings is 8 * w =$8w
price of q quesadillas is 10 * q = 10q
The maximum amount to spend is $160
Thus, the addition will be;
8w + 10q ≤ 160

Emma borrowed $89.40 from her sister. She determines that she can pay her back the total over six months. Which number reflects the monthly change in her balance?
Answer:
$14.9
Step-by-step explanation:
Step one:
given data
we are told that Emma borrowed $89.40 from her sister to pay her back in 6 months.
let us solve for the amount she is to pay her sister every month.
amount to be paid per month= 89.40/6
=$14.9
So that every month she pays back her sister $14.9
we don't know her balance but every month there will be a deduction.
Hence the monthly change in her balance is reflected by a deduction of $14.9

Which of these statements best describes the relation shown in Item 1?
A- A function that is one-to-one
B-A function that is many-to-one
C-A function that is one-to-many
D-A relation that is not a function
Answer:
The relation is 'a function that is one-to-many'.
Step-by-step explanation:
From the table, we can see that element 10 i.e. y=10 in the range, corresponds to two elements i.e. x=-5, and x=5 in the domain.
In other words, the given table represents the many-to-one function as an element of the range y = 10 corresponds to more than one element in the domain.
Therefore, the relation is 'a function that is one-to-many'.
The statements that best describe the relation shown in Item 1 is one to many. Option C is correct
Functions are represented as mappings to relate the domain of the given function with the co-domain.
For instance, the function y= x + b has a domain of x and the codomain of "y"
Mappings can be one to one, where each value of the domain is a unique value in the co-domain
Many to one where one element in the domain have more than one element in the codomain
From the given table, we can see that when y = 10, the corresponding x values are 5 and -5. his shows that the codomain value (10) has more than one unique value in the domain.
Hence the statements that best describe the relation shown in Item 1 is a one to many

One of the slowest fish is the blenny
fish. The function y = 0.5x describes
how many miles y the fish swims in
x hours. Graph the function. Use the
graph to estimate the number of miles
the fish swims in 3.5 hours.
.
Answer:
It swims 1.75 miles in 3.5 hours. X stands for hours so x=3.5. Y stands for miles so y=1.75.
Step-by-step explanation:
your equation is y=0.5x
we know x=3.5
so y= 0.5(3.5)
solve and you get y= 1.75
so in (x,y) intercept format (3.5,1.75) and you can make a graph and label your x intercepts hours and your y intercepts miles traveled.
The number of miles the fish swims in 3.5 hours is 1.75 miles.
The equation of a straight line is:
y = mx + b;
y, x are variables, m is the slope of the line and b is the y intercept.
Given the function: y = 0.5x;
where y represent the miles the fish swims in x hours.
The graph of the function is plotted using geogebra online graphing tool.
From the graph, the number of miles the fish swims in 3.5 hours is 1.75 miles.
