Answer:
y=3x+1
Step-by-step explanation:
First, we have to find the slope. [tex]\frac{4-(-5)}{2-(-1)}[/tex] This comes out to 9/3. This becomes 3. Now we need to find the y-intercept. Now write out how to find the answer. 4=3(2)+b. 4=3+b. Subtract 3 from both sides to get 1=b. Now write out the equation. y=3x+1
Abigail can read 180 words in one minute if she were to read 30 minutes each day how many days would it take to read 32,400 words of a book
Answer:
It would take Abigail six days to read 32,400 words of a book if she were to read 30 minutes per day.
Step-by-step explanation:
If Abigail reads 180 words per minute, and she reads 30 minutes per day, we need to multiply 180 by 30 to figure out how many words she reads per day.
180 × 30 = 5,400
Abigail reads 5,400 words per day.
Then, we divide 32,400 by 5,400 to figure out how many days it would take Abigail to read 32,400 words.
32,400 ÷ 5,400 = 6
It would take Abigail six days to read 32,400 days.

Here are the diameters of four coins: penny (1.9 cm), nickel(2.1cm), dime (1.8cm), quarter (2.4cm). A coin rolled about 33 cm in 5 rotations. Which coin is it? Use 3.14 for pi
Answer: Nickel
Step-by-step explanation:
Hi, to answer this we have to calculate the circumference of each coin:
C =π diameter.
Penny = 3.14 (1.9)= =5.96 cm
Nickel = 3.14 (2.1) =6.6 cm
Dime = 3.14 (1.8) =5.62 cm
Quarter = 3.14 (2.4) =7.53 cm
Since the coin rolled about 33cm in 5 rotations, it means that the circumference of the coin (x) multiplied by 5 is equal to the distance rolled.
5x=33
x =33/5 =6.6 cm
The coin is the nickel, because its circumference is equal to 6.6 cm.

Which expression has exactly three terms? Select all the expressions that apply.
A. 3x
B. y^3
C. xyz
D. x+y+1
E. x+y+z
F. y^3−2y^2+y−1
G. 4x^3+10x^4−7x
H. ( x+1)( y−2 )( z+5 )
The answer is expressions D, E, and G.
In algebra, a ‘term’ usually means the different parts of an expression that are separated by + and - signs.
Options A and B only have 1 term, an x or y³, so these are incorrect.
Option C has 1 term as well, ‘xyz’, because they are all multiplied together which makes it one term.
D and E both have 3 terms each, but F has 4 unique terms so this is incorrect also.
G has 3 unique terms, x³, x^4, and 7x, so this is correct.
When H is expanded, you will end up with more than 3 unique terms, so this is incorrect.
I hope this helps!
Answer:

A rectangular flower garden in Samantha’s backyard has 260 feet around its edge the with garden is 60 What is the length of the garden
Answer:
70 ft
Step-by-step explanation:
260 feet around its edge means perimeter
P = 2(l+w)
Width = 60
260 = 2( l+60)
Divide each side by 2
260/2 = 2/2(l+60)
130 = l+60
Subtract 60 from each side
130-60 = l+60-60
70 = l
The length is 70 ft

Martin deposits $700 into a savings account that gains interest at a rate of 5.5% annually. If he waits 7 years to withdraw the money, will he have earned more or less money than $275 and by how much?
｡☆✼★ ━━━━━━━━━━━━━━ ☾
Use the multiplier 1.055
final = original x multiplier^n
where 'n' is the number of years
Sub the values in
final = 700 x 1.055^7
final = 1018.27
Subtract the values:
1018.27 - 700 = 318.27
Thus, he earns more than $275

Answer:
Relative frequency is 7.41% or 0.0741
Step-by-step explanation:
Given
The Attached Table
Required
Calculate the relative frequency of the class with lower limit 27
Relative Frequency is calculated by dividing individual frequency by the total frequency
Mathematically,
[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex]
The total frequency of the given data is 6+8+4+2+5+2
[tex]Total\ Frequency = 27[/tex]
The class with lower limit 27 has a frequency of 2;
Hence;
[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex] becomes
[tex]Relative\ Frequency = \frac{2}{27}[/tex]
[tex]Relative\ Frequency = 0.07407407407[/tex]
[tex]Relative\ Frequency = 0.0741[/tex] (Approximated)
You may also leave your answer in percentage form
[tex]Relative\ Frequency = 0.0741 * 100\%[/tex]
[tex]Relative\ Frequency = 7.41 \%[/tex]
Hence, the relative frequency is 7.41% or 0.0741

what is the answer: -4 - 2
First change -4 - 2 to -4 + -2.
Now we can use our number line to
help us visualize what's going on.
Starting at 0, -4 moves us 4 units to the left along our number line.
From there, another -2 moves us 2 more units to
the left along the number line and we end up at -6.
So -4 + -2 simplifies to -6.

Answer:
a = 4.5 units
b = 7.5 units
Step-by-step explanation:
By using mean proportional theorem in the ΔACB,
ΔACB ~ ΔADC ~ ΔCDB
[tex]\frac{AD}{CD}=\frac{CD}{DB}[/tex]
[tex]\frac{8}{6}=\frac{6}{a}[/tex]
a = [tex]\frac{6\times 6}{8}[/tex]
a = 4.5
[tex]\frac{AB}{CB}=\frac{CB}{DB}[/tex]
[tex]\frac{(a+8)}{b}=\frac{b}{a}[/tex]
Since a = 4.5
[tex]\frac{4.5+8}{b}=\frac{b}{4.5}[/tex]
b² = 4.5 × 12.5
b = √56.25
b = 7.5 units
Therefore, a = 4.5 units and b = 7.5 units will be the answer.

Formula for Fahrenhelt temperature F=32+ 9/5C For C
Answer:
[tex]C=\dfrac{5}{9}(F-32)[/tex].
Step-by-step explanation:
The formula for Fahrenheit temperature is
[tex]F=32+\dfrac{9}{5}C[/tex]
We need to write this formula for C.
Subtract 32 from both sides.
[tex]F-32=\dfrac{9}{5}C[/tex]
Multiply both sides by 5.
[tex]5(F-32)=9C[/tex]
Divide both sides by 9.
[tex]\dfrac{5}{9}(F-32)=C[/tex]
Therefore, the required formula is [tex]C=\dfrac{5}{9}(F-32)[/tex].
1.) A school wants to have a metal gate placed around it. However they only want to cover three sides of the school and they only have 2000 feet of gate. What are the dimensions of the school if the area is 240,000 square feet?
2.) A backyard is in the shape of a rectangle. The distance around the yard is 280 feet and it has an area of 2,400 square feet. What are the dimensions of the yard?
Answer:
I only have an answer to number 2 but the dimensions are 20 and 120.
Step-by-step explanation:
well you can remove the zeroes and factor either the 28 or 24. (I think 24 is the best) so when you factor it you get 2 and 12 because 2 x 12 is 24 and 2 + 2 + 12 + 12 is 28. Then add the zeroes and you have your dimensions. I hope that explanation helped with number 2.

The center of your park has a pool. The pool is the shape of a rectangular prism. The volume of the pool is 189 cubic feet. If the length of the pool is 7 yards and the width is 3 yards, how deep is the pool? (Hint: 3 feet = 1 yard)
Answer:
3 yards
Step-by-step explanation:
First, let's convert yards into feet. 189 feet is 63 yards.
Volume=L•W•H L=length W=width H=height
To do this we have to divide the volume by the product of the length and width and it will calculate the height.
Solving for the width:
63÷(7•3)=3 yards <-the depth of the pool
Answer:
3 yards

y=x^{2} +2x-8 determine the axis of symmetry, the vertex point and find the roots by factoring
Answer:
x = -1 <--- axis of symmetry
(-1, -9) <-- vertex
2, -4 (or, in my old precalc class we wrote our roots as (2,0) and (-4,0)) <--- roots
Step-by-step explanation:
a) Axis of symmetry equation is defined as
[tex]-b/2a[/tex] = x (i memorized this)
Quadratic equation form:
[tex]ax^2+bx+c[/tex]
And our original equation:
[tex]x^2+2x-8[/tex]
So..
[tex]-2/2 = - 1[/tex]
So our axis of symmetry is at x = -1,
b) now vertex point can be found by plugging this value back into our original equation.
y = [tex](-1)^2+2(-1)-8[/tex]
y = 1 - 2 - 8
y = - 9
So our vertex is at (-1, -9)
c) Finally, lets factor
[tex]x^2+2x-8[/tex] = 0 (when finding the roots, set y = 0, because we are trying to find where we cross the x-axis)
[tex]x^2-2x+4x-8[/tex] = 0
[tex]x(x-2) + 4(x-2) = 0[/tex]
[tex](x-2)(x+4)=0[/tex]
x = 2; x = -4 <--- Roots
