Step-by-step explanation:
A rectangle has a length of y^2+3y+7 and a width of y-3. How much longer is the length?
Given:
The length of the rectangle = [tex]y^2+3y+7[/tex]
Width of the rectangle = [tex]y-3[/tex]
To find:
How much longer is the length?
Solution:
We need to find the difference between length and width of the rectangle.
[tex]Difference=Length-Width[/tex]
[tex]Difference=y^2+3y+7-(y-3)[/tex]
[tex]Difference=y^2+3y+7-y+3[/tex]
[tex]Difference=y^2+(3y-y)+(7+3)[/tex]
[tex]Difference=y^2+2y+10[/tex]
Therefore, the length of the rectangle is [tex]y^2+2y+10[/tex] much longer than the width.

Answer:
a) IJ is median
IJ = 1/2(HG + EF)IJ = 1/2(8 + 12) = 10 cmb) I is midpoint of HE, therefore, HI = IE
Substitute values and solve for x:
10 = x - 4x = 10 + 4x = 14 cmAnswer:
a) IJ is median
IJ = 1/2(HG + EF)
IJ = 1/2(8 + 12) = 10 cm
b) I is midpoint of HE, therefore, HI = IE
Substitute values and solve for x:
10 = x - 4
x = 10 + 4
x = 14 cm
Step-by-step explanation:
find the measure of each interior angle of a regular polygon with the following number of sides 10
Answer:
a regular polygon has all angles measure sum up to 360 degrees so each interior angle = sum of alll angles/no.of sides so it is 360/10= 36 degrees hope its clear now

list some values that would make this inequality -2x>10
Answer:
-6,-9,-20,-25.
Step-by-step explanation:
You need to multiply a negative to make it positive as a negative multiplied by a negative equals a positive. But anything besides -1,-2,-3,-4,-5 and all positves can be placed.
help please in this question?
Answer:
see explanation
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles and are supplementary, sum to 180° , so
5x + x + 54 = 180 ← equation to solve to find x
6x + 54 = 180 ( subtract 54 from both sides )
6x = 126 ( divide both sides by 6 )
x = 21
Then
∠ 1 = 5x = 5 × 21 = 105°
∠ 2 = x + 54 = 21 + 54 = 75°
Would you use the median or mean to describe the center of each data set? Explain your reasoning. Heights of 50 basketball players
Answer:
Median is used to describe the center of the data of heights of 50 basketball players.
Step-by-step explanation:
The median divides the data into two equal parts.
It can be used to describe the center of the data.
The mean gives the average where most data lies.
The advantages of median are
1)it is located even when the values are not capable of quantitative measurements.
2) It is not affected by extreme values > It can be computed even when a frequency distribution involves open end classes like those of income and prices.
3) In a highly skewed distribution median is appropriate average to use.
The disadvantages of the mean are
1) it is greatly affected by extreme values.
2) It sometimes gives fallacious conclusions.
3) In a highly skewed distribution mean is not an appropriate average to use.
4) It cannot be computed even when a frequency distribution involves open end classes like those of income and prices.
The length of a rectangular swimming pool is exactly three times as long as its width. If the pool has a perimeter of 400m find the width of the pool.
Answer:
50m
Step-by-step explanation:
let the width be x
length=3x
3x+3x+x+x=400
8x=400
x=400÷8
x=50
Write an equation of a line in slope-intercept form that has a slope of -5 and passes through the point (-3, -4).
Answer:
y = -5x - 19
Step-by-step explanation:
y = -5x + b
-4 = -5(-3) + b
-4 = 15 + b
-19 = b
Mr. Smith's class has 28 students. They all put in an equal amount of money to get Mr. Smith an end of year gift. If they collected $168 altogether, how much money did each student give. For each question, define a variable (Let statement), write and solve an equation
Answer:
Step-by-step explanation:
28 students all give $128
so,
[tex]\sqrt[28]{128}[/tex]= v v=6
Each student gave 6 dollars. This is true due to the fact that
[tex]\sqrt[28]{128}[/tex]=6
28X6=128
Jared made a scale drawing of his classroom for his tech project. He used a scale of 1 cm = 3.5 ft. If the length of his classroom on the drawing measured 30 cm, What is the actual length of his classroom?
Answer: 105ft
Step-by-step explanation: If 1cm is 3.5ft then you should multiply 3.5ft by 30 cm to get 105ft.

1). What are the vertices of the hyperbola whose equation is:
( y + 6 ) ² ( x + 8 ) ²
_____ - _____
81 49
2). What are the foci of the hyperbola whose equation is:
( x - 6 ) ² ( y + 7 ) ²
_____ - _____
16 9
Answer:
1) The vertices of the hyperbola are (-8, -15), (-8, 3)
2) The foci of the hyperbola are (11, -7) or (1, -7)
Step-by-step explanation:
1) The vertices of a hyperbola given in the form [tex]\dfrac{\left (y - k\right)^2}{a^2} -\dfrac{\left (x - h\right)^2}{b^2} = 1[/tex] is (h, k ± a)
Therefore, for the given hyperbola with the following equation;
[tex]\dfrac{\left (y + 6\right)^2}{81} -\dfrac{\left (x + 8\right)^2}{49} = 1[/tex], we have;
[tex]\dfrac{\left (y + 6\right)^2}{9^2} -\dfrac{\left (x + 8\right)^2}{7^2} = 1[/tex]
Therefore the vertices are;
(-8, -6 ± 9) = (-8, -15), (-8, 3)
2) The equation of the given hyperbola is presented as follows;
[tex]\dfrac{\left (x - 6\right)^2}{16} -\dfrac{\left (y + 7\right)^2}{9} = 1[/tex]
The given hyperbola is of the form;
[tex]\dfrac{\left (x - h\right)^2}{a^2} -\dfrac{\left (y - k\right)^2}{b^2} = 1[/tex]
We get;
[tex]\dfrac{\left (x - 6\right)^2}{4^2} -\dfrac{\left (y + 7\right)^2}{3^2} = 1[/tex]
The foci is then (h ± c, k)
Therefore, by comparison, the foci of the given hyperbola is (6 ± c, -7)
Where c² = a² + b²
∴ c² = 4² + 3² = 25
c = √25 = 5
∴ The foci; (6 ± 5, -7) = (11, -7) or (1, -7).

A line passes through the points (0.5) and (-6,3). A second line passes through
(-15, 0) and (-21, -2).
A) Do the lines intersect? Show work to prove it! Grcle YES or
NO
Answer:
Step-by-step explanation:
Find the slope of each line. If the slopes are the same, the lines are parallel. Otherwise, the lines intersect.
Slope of line passing through (x₁, y₁) and (x₂, y₂) = (y₂-y₁)/(x₂-x₁)
Slope of line passing through (0, 5) and (-6, 3) = (3-5)/(-6-0) = ⅓
Slope of line passing through (-15, 0) and (-21, -2) = (-2-9)/(-21-(-2)) = 11/19
The lines intersect.
