(1,0)→(-1,0)
angela bought a pair of shoes at 12% off and receive an additional membership discount of 70 pesos if the pair of shoes cost her 1866 pesos what was the original price of the shoes
Answer:
The original price of the shoes was of 2200 pesos
Step-by-step explanation:
She bought the shoes for 1866 pesos.
She receibed a discount of 70 pesos, so the cost, with the discount, is 1866 + 70 = 1936 pesos.
The pair was bought at 12% off, that is, 1936 pesos is 100 - 12 = 88% of the original price. Then
[tex]0.88x = 1936[/tex]
[tex]x = \frac{1936}{0.88}[/tex]
[tex]x = 2200[/tex]
The original price of the shoes was of 2200 pesos
Which expression is equal to c2−4c+412c3+30c2÷c2−46c4+15c3?
Answer
A: c (c-2)/ 2 (c +2)
Step-by-step explanation:
Which is equal to c^2-4c+4/ 12c^3+ 30c^2 divided by c^2-4/ 6c^4 +15c^3?
A: c (c-2)/ 2 (c +2)
B: 2 (c-2)/ c(c+2)
C: 2 (c+2)/ c(c-2)
D: c(c+2)/ 2(c-2)
[c^2 - 4c + 4] / [12×(c^3) + 30×(c^2)] ÷ [c^2 - 4] / [6×(c^4) +15×(c^3)]
Expand the expression
= [c^2 - 2×2×c + 2^2] / [6×(c^2)×(2c + 5)] ÷ [c^2 - 2^2] / [3×(c^3)×(2c +5)]
Factorize the expression
= [(c-2)^2] / [6×(c^2)×(2c + 5)] ÷ [(c-2)(c+2)] / [3×(c^3)×(2c +5)]
Multiply by interchanging the numerator and denominator of the divisor
= [(c-2)^2] / [6×(c^2)(2c + 5)] × [3(c^3)(2c +5)] / [(c-2)(c+2)]
= [(c-2)×3(c^3)] / [6×(c^2)×(c+2)]
= [c×(c-2)] / [2×(c+2)]
= c(c - 2) / 2(c + 2)
[c^2 - 4c + 4] / [12×(c^3) + 30×(c^2)] ÷ [c^2 - 4] / [6×(c^4) +15×(c^3)] = c(c - 2) / 2(c + 2)
Answer:
A: [tex]\frac{c(c-2)}{2(c+2)}[/tex]
Step-by-step explanation:
[tex]\frac{c^{2} -4c+4}{12c^{3} + 30c^{2}}[/tex] ÷ [tex]\frac{c^{2} -4}{6c^{4} + 15c^{3}}[/tex]
expand.
= [c^2 - 2×2×c + 2^2] / [6×(c^2)×(2c + 5)] ÷ [c^2 - 2^2] / [3×(c^3)×(2c +5)]
factorize.
= [(c-2)^2] / [6×(c^2)×(2c + 5)] ÷ [(c-2)(c+2)] / [3×(c^3)×(2c +5)]
multiply by the reciprocal.
= [(c-2)^2] / [6×(c^2)(2c + 5)] × [3(c^3)(2c +5)] / [(c-2)(c+2)]
= [(c-2)×3(c^3)] / [6×(c^2)×(c+2)]
= [c×(c-2)] / [2×(c+2)]
= A: [tex]\frac{c(c-2)}{2(c+2)}[/tex]

How much is 10% of 10 liters of milk
Answer:
1 liters
Step-by-step explanation:
A linear function is expressed by a graph of a line that
crosses both axes at the origin. An equation is written in
siope-intercept form to express the same function as
shown in the graph From just this information what
statements can be made?
Choose the true statements
The slope of the equation must be positive.
The y-intercept of the equation is zero.
It is possible that the ine on the graph is horizontal
The slope of the equation must be negative
Answer:
The y-intercept of the equation is zero. It is possible that the line on the graph is horizontal.
Step-by-step explanation:
Answer:
The y-intercept of the equation is zero.
It is possible that the ine on the graph is horizontal
Step-by-step explanation:
The only thing we know for sure is that the function goes through the point (0,0). The line y = 0 passes through (0,0), so it is possible that the line on the graph is horizontal. Since x = 0 where y = 0, the y-intercept is also 0. However, we have no way of knowing for sure what the slope of the equation is.

27.) Find the sum of the length of line segments EF and CD
Answer:
5√10
Step-by-step explanation:
The distance between two points A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2[/tex]) on the coordinate plane is given by:
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2 }[/tex]
From the image attached the coordinates of the points are E(-1, -1), F(8, -4), C(-7, -4) and D(-1, 2).
Hence the lengths of the line segment EF and CD are:
[tex]|EF|=\sqrt{(8-(-1))^2+(-4-(-1))^2} =\sqrt{90}=3\sqrt{10} \\\\CD=\sqrt{(-1-(-7))^2+(-2-(-4))^2}=\sqrt{40} =2\sqrt{10} \\\\Therefore:\\\\|EF|+|CD|=3\sqrt{10} +2\sqrt{10} =5\sqrt{10}[/tex]

A ruler cost x pence a pen costs 10 pence more than the ruler write an expression in terms of x for the cost of the pen
Answer:
(A ruler) = X (a pen) = Y
y = x+10
Step-by-step explanation:
Answer:
A ruler cost x pence.
Let the cost of the ruler be x pencePen costs 10 pence more than the ruler
Therefore, the pen cost (x+10) pence(x+10) is the right answer.If k is a constant, what is the value of k such that the polynomial 2ky^-kx-8 is divisible by (x-2)
Answer:we have that
k² x³-6kx+9
we know that
The Remainder Theorem says: If the polynomial f(x) is divisible by a bynomial (x-a) then the number "a" is a root of the polynomial f(x)
so
x=1 is a root of the polynomial
therefore
for x=1
k² x³-6kx+9=0--------> k² (1)³-6k(1)+9=0-----> k²-6k+9=0
using a graph tool------> to resolve the second order equation
the solution is
k=3
k=3
k²-6k+9=0---------> (k-3)²=0
the answer is
k=3
Answer:
Ok so if I did this right the answer will be 2ky^kx-8 / x -2

What is the slope of the line?
-3, 3
-4, -1
9514 1404 393
Answer:
4
Step-by-step explanation:
Assuming the given numbers are supposed to be (x, y) ordered pairs, the slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (-1 -3)/(-4 -(-3)) = -4/-1 = 4
The slope of the line through the points (-3, 3) and (-4, -1) is 4.
What are the mean,median,mode and range of 59,63,63,72,72,72,72,72,76,81,83,84,84,93.
Answer:
mean 74.714285714286
median 72
mode 72
range 34
Step-by-step explanation:
Answer:
Mean: 74.71
Median: 72
Mode: 72
Range: 34
Step-by-step explanation:
First, let's define what each of these terms mean:
Mean: the average of the data
Median: the number in the middle after being put in ascending order
Mode: the number listed the most
Range: the highest number minus the smallest number
To find the mean, just add up all the numbers and divide by how many there are. First, add up all the numbers in the set. This should give you 1,046. Next, divide by how many terms there are. Since there are 14 terms in this set, we'll be dividing 1,046 by 14. This will give us a mean of 74.71 or 75 if you're rounding up.
To find the median, you'll first need to put the terms in ascending order, meaning from lowest to highest. Luckily, the set is already in ascending order, so that step is not necessary here. Next, you're going to find the number in the middle of the set. However, since there are an even number of terms, we have two numbers in the middle: 72 and 72. To find the median with two numbers in the middle, just add both terms up and divide by 2. However, since both terms are 72, this step is also not necessary. Our median is simply 72.
To find the mode, you're just looking for the number that appears the most. In this case, it would be 72 since it appears more than any other number in the set (5 times.)
Last, to find the range, just subtract the lowest number from the highest number in the set. With the highest number being 93 and the lowest being 59, just do 93 - 59 for a range of 34. Please let me know if you have any further questions!
The difference of two complementary angles is 20. Find the measure of each angle
Answer:
35° , 55°
Step-by-step explanation:
Let one angle be x.
It's complementary angle is = (90 - x)°
According to the question ,
[tex]x - (90 - x) = 20[/tex]
[tex]=> x - 90 + x = 20[/tex]
[tex]=> 2x = 90 - 20 = 70[/tex]
[tex]=> x = \frac{70}{2} = 35[/tex]
