Answer:
Infinite solutions
Step-by-step explanation:
Equation 1:
4x-6y=4
3(4x-6y=4)
12x-18y=12
Equation 2
(12x-18y=12)/3
4x-6y=4
They are the same equation, therefore, there are infinite solutions
Sandy paid $27 for her new sweater. If the sweater was on sale for 25% off, what was the original price?
Answer:
The answer is $36
Step-by-step explanation:
Took the Star Math Test
Answer:
$36
Step-by-step explanation:
100% - 25% = 75%
75% as a decimal = 0.75
75% = 27
75% as a decimal = 3/4
So 3/4 x = 27
27 x 4 = 108
108 / 4 = 36

Estimate 11.14+9.543 by first rounding each number to the nearest tenth.
HELP PLSZZ
To round each number to the nearest tenth, we have to look at the second digit after the decimal point, the hundredths. We look at tenths to round whole numbers, hundredths to round tenths, thousandths to round hundredths, etc. If the digit is 4 or below, then we would round down. If the digit is 5 or up, we would round up.
11.14
The digit is below 5, so we round down to 11.1.
9.543
The digit is also below 5, so we round down to 9.5.
Henceforth, adding these two numbers, we can conclude that an accurate estimation of the sum is 11.1 + 9.5, or 20.6.
If we wanted to round this answer further, we would use the same rounding rule. 20.6, where the tenths place digit, 6, is above 5, would be rounded up to 21.

Use the information given to write the equation of the circle
Center: (-9, -3), Point on Circle: (-11,2)
x²+ y²+ 20x + 8y - 84 = 0 is equation of the circle .
What is a circle, exactly?
A circle is a closed, two-dimensional object in which all points in the plane are equally spaced apart from the center.
The symmetry line of reflection is formed by each line that traverses the circle. Additionally, it is rotationally symmetric about the center for all angles.
the equation of the circle with center (-10,-4) and a point on the required circle is (4,-2).
Clearly, radius of the circle will be distance between the center and the point on the circle.
r = √( -10 - 4 )²+ ( -4 + 2 )²
r = √196 + 4
r = 10√2
We know that circle with center at (h.k) and radius r has the equation
( x - h )² + ( y - k )² = r²
We have circle with radius 10√2 and center at (-10,-4) and its equation will be
( x+ 10 )² + ( y + 4)²= ( 10√2)²
x²+ y²+ 20x + 8y - 84 = 0

TWO points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6 cm long, find the scale used to draw the plan.
Answer:
The scale used to draw the plan is 1: 200.
Step-by-step explanation:
Given that two points A and B on a plan represent two localities 12 m apart, to determine, given that the segment AB is 6 cm long, the scale used to draw the plan, the following calculation must be performed:
12 m = 12 cm x 100 = 1200 cm
1200/6 = 200
Therefore, the scale used to draw the plan is 1: 200.

Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually. How much will the investment be worth after 5 years? Round to the nearest dollar.
The investment worth after 5 years to the nearest dollar will be $3601.
What is compound interest?We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually.
The worth of investment after 5 years is calculated as,
A = $3,069 x (1 + 0.0325)⁵
A = $3,069 x 1.0325⁵
A = $3,069 x 1.1734
A = $3601
The investment worth after 5 years to the nearest dollar will be $3601.

Find the value of X please help
Answer:
x = 119°
Step-by-step explanation:
The angle between chord KJ and chord LM is half the sum of the arcs intercepted by the angle and its vertical angle, that is
[tex]\frac{1}{2}[/tex] (75 + 47)° = 0.5 × 122° = 61°
This angle and x are adjacent angles and sum to 180° , then

Seventy percent of kids who visit a doctor have a fever, and 30% of kids with a fever have sore throats. What’s the probability that a kid who goes to the doctor has a fever and a sore throat?
Answer:
0.21
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
Probability that a kid who goes to the doctor has a fever and a sore throat = probability a child would have fever x probability a child would have a sore throat

A glide reflection is a composition of a line reflection and a translation that is parallel to the line of reflection. Unlike some composition of transformations, a glide reflection IS ____________________. Therefore, the line reflection and translation can be done in any ____________.
Answer:
" a glide reflection IS commutative. Therefore, the line reflection and translation can be done in any order."
Step-by-step explanation:
Transformations can be written as operators that act on functions or shapes.
For example, we can define the horizontal translation operator as:
T(k)
And if we apply this to a function, we get:
T(k)[ f(x) ] = f(x - k)
Now, the operators are not necessarily commutative.
This means that if we have two operators:
K and L
is not the same:
K[ L[ f(x) ]]
than:
L[ K[ f(x) ]]
An example of this can be a reflection across the y-axis and a horizontal translation, that composition is non-commutative.
Now, let's go to our case.
A glide reflection is commutative, so we can perform the transformations in any order, then the statement is:
" a glide reflection IS commutative. Therefore, the line reflection and translation can be done in any order."
