A clothing store is having a sale on shoes of 40% off the original price. They have not marked the new price on any of the shoes. Write an equation that you could use to determine the price of a pair of shoes sold by the store if you know the original price. Use x to represent the original sale price and y to represent the sale price.
Answer:
x * 0.60 = y
Step-by-step explanation:
0.60 because 100% - 40% =60% 60%=0.60

(The "-" sign turned positive because it is negative times negative)
5/-5
Simplify: 5/-5 = -1 = -x
The slope of this line is -x
a) (i) Write down the value of x.
(ii) Give a reason for your answer.
b) (i) Write down the value of y.
(ii) Give a reason for your answer.
c) Work out the size of angle z.
Answer:
see explanation
Step-by-step explanation:
x = 65° ( vertically opposite angles )
y = 71° ( alternate angles )
The sum of the 3 angles in a triangle = 180° , then
x + y + z = 180° , that is
65° + 71° + z = 180°
136° + z = 180° ( subtract 136° from both sides )
z = 44°
So x = 65°, y = 71° , z = 44°
Which statement best describes the equation (x 5)2 4(x 5) 12 = 0?.
Answer:
Option 1 is correct.
Step-by-step explanation:
Given the equation
we have to choose the best statement describes the above equation.
→ (1)
As, the highest degree of its monomials i.e individual terms with non-zero coefficients is 2.
⇒ Degree of above equation is 2.
hence, the given equation is quadratic equation.
The general form of quadratic equation is
In variable u: → (2)
Now, compare equation (1) with (2), we say that
The equation is quadratic in form because it can be rewritten as a quadratic equation with u substitution u = (x + 5).
Option 1 is correct.

The equation of a circle is pi(2x+3)^2
What is the least possible integer value of x for the circle to exist? Please explain.
Answer: x = -1
Step-by-step explanation:
The radius needs to be positive, so 2x + 3 > 0. Solving for x, we get x > -3/2. The smallest integer larger than -3/2 is -1, so x = –1.

What side lengths form a right triangle?
It says I need more than 1 answer
In a right triangle has one leg that measures 11 in and the hypotenuse measures 47 in, what is the length of the other leg?
Using the Pythagorean theorem:
47 ^2 = 11^2 + x^2
2209 = 121 + x^2
Subtract 131 from both sides
2088 = x^2
Take the square root of both sides
X = sqrt(2088)
Simplify
X = 6sqrt(58)
Find x in this proportion.
16 = X
x. = 4
O 64
O 16
O 32

Answer:
32
Step-by-step explanation:
16/x = x/4, then cross multiply:
16 times 4 = 64
x times x = 2x
64 = 2x
/2 /2
32 = x
hope this helps!
this question is very confusing are u trying to find the proportion of Find x in this proportion.
16/x = x/4 if so the answer is 8
Step-by-step explanation: because 16 divided by 8 is 2 and 8 divided 4 is 2
Your grandparent says you should always buy as much auto insurance coverage as you can afford to pay. Would you agree or disagree? Explain why.
Buying as much auto insurance as you can afford is not the best idea.
What is auto insurance?Auto insurance is a type of insurance that provides you the following benefits:
Coverage of expenses in case you have an accident in your car including medical expenses.Coverage in case your car is damaged or stolen.Coverage in almost any situation that involves your car.How much do you need to pay for auto insurance?Payments are agreed by customers, this means you can pay as much as you can, and by paying more you will have a wider coverage.
Despite this, investing as much money as is possible is not a good idea because incidents such as accidents are not so common and if you never experience one, the insurance is useless.

What is X equal to? It’s not 180 -.-
Answer:
x = 163
Step-by-step explanation:
(x-5)+22= 180
x = 143
hope this helps!!!
Answer:
x = 163
Step-by-step explanation:
It is 180 and there is no doubt in it. a straight line always measures 180 and this is a straight line not even curved
to find the value of x
x - 5 + 22 = 180
x + 17 = 180
x = 180 - 17
x = 163
we can even cross check
163 - 5 + 22
158 + 22
= 180
if the line wasn't 180 I wouldn't able to cross- check
f(x)=50x^4+3x^3-10x^2x^7-100

Graph the line that has a slope of 10 and includes the point (0, 0).
Answer:
See attached graph
Step-by-step explanation:
The equation that has a slope of 10 and intersects (0,0) is:
y = 10x
The slope-intercept form of a straight line equation is y=mx+b, where m is the slope and b the y-intercept (the value of y when x = 0).
In this case:
m = 10
b is 0 since the value of y when x = 0 is 0 (0,0).
See attached graph.
[tex]\huge\fbox{Hi\:there!}[/tex]
We are given the slope of the line and a point that it passes through, so we can use the Point-Slope formula:
[tex]\rm{y-y1=m(x-x1)[/tex]
Where
y1 is the y-coordinate of the point, m is the slope and x1 is the x-coordinate.
In this case:
y1=0
m=10
x1=0
Plug in the values:
[tex]\bf{y-0=10(x-0)[/tex]
Solve:
[tex]\bf{y-0=10x[/tex]
[tex]\bf{y=10x}[/tex]
Now, how to graph the line?
Let's look at its equation.
First of all, it has a y-intercept of 0, which means the line touches the y-axis at (0,0)
Now, what about the slope? The slope is 10.
Thus
We move "up 10, over 1, up 10, over 1" and so on, until we have a line.
Then all we have to do is take a ruler and connect the points.
