Answer:
y = 6x - 47
or
6x - y - 47 = 0
Step-by-step explanation:
[tex]y - y_{1} = m(x - x_{1} ) \\ \\ plug \: x_{1} = 7 \\ y_{1} = - 5 \\ m = 6 \: in \: the \: above \: equation \\ y - ( - 5) = 6(x - 7) \\ \\ y + 5 = 6x - 42 \\ \\ y = 6x - 42 - 5 \\ \\ y = 6x - 47 \\ \\ or \: 6x - y - 47 = 0[/tex]

10x+50= 5x-25 solve for X
Answer:
-15
Step-by-step explanation:
10 x -15 = -150
-150 + 50 = -100
5 x -15 = -75
-75 - 25 = -100

Step-by-step explanation:
find the Sum of two consecutive odd numbers plus eighteen is 170
Answer:
75, 77
Step-by-step explanation:
Let the first odd number = 2x -1
Let the second odd number = 2x + 1
2x - 1 + 2x + 1 + 18 = 170 Combine like terms on the left.
4x + 18 = 170 Subtract 18 from both sides.
4x = 170 - 18 Combine like terms on the right
4x = 152 Divide by 4
4x/4 = 152/4
x = 38
2 * 38 - 1 = 75
2 * 38 + 1 = 77
3.) 2x + 4 = -3x - 2; x = 1
Determine if the value of x is a solution to the equation
Answer:
x = 1 is not a solution to the equation
Step-by-step explanation:
2x + 4 = -3x - 2 x = 1
2(1) + 4 = -3(1) - 2
2 + 4 = -3 - 2

the sliding board is 15 feet long and meets the ground at a 40 degree angle. what is the height of the ladder?
Answer:
9.6 ft
Step-by-step explanation:
Sin=opposite/hypotenuse
The required height of the ladder is 9.6 feet.
Given that,
The sliding board is 15 feet long and meets the ground at a 40-degree angle.The height of the ladder is to be determined.
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
Here,
Let the height of the ladder be p
Now, applying trigonometric operations,
sin 40 = p / 15
p = 15 sin40
p = 0.64 * 15
p = 9.6
Thus, the required height of the ladder is 9.6 feet.

Write the explicit formula for the arithmetic sequence 11, 14, 17, 20, . . . What is term number 54 in this sequence?
Answer:
Answer:
15 or 16. 54 is not listed.
Step-by-step explanation:
pretend that 11 is 0. that means 54 is 43.
then you do 43 divided by 3 or 43/3
but looks like the number 43 isn't divisible. it is 14.33333 repeating decimal.
Same if you really use your time and count. So i dont know if u meant 53 it will be 53 if you meant 56 it will be 16.
Answer:
see explanation
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = a₂ - a₁ = 14 - 11 = 3, then
[tex]a_{n}[/tex] = 11 + 3(n - 1) = 11 + 3n - 3 = 3n + 8
Thus
a₅₄ = 3(54) + 8 = 162 + 8 = 170

A bank loans a customer $87,000 for a period of 15 years. The simple interest rate of the loan is 9.2%. What is the total amount that the customer will need to pay the bank over the 15 years?
Answer:
h. 207, 060
Step-by-step explanation:
Answer:
I= 120,060
Step-by-step explanation:
formula I=prt
Interest:
Principal: 87,000
rate:9.2% = 0.092
time: 15 year
I= 87,000(0.092) (15)
I= 87,000 (1.38)
I= 120,060
Sarah made a certain number of bracelets for a craft show. Maria made 7 more than Sarah. Julie made 3 times as many as Maria. Which expression represents the total number of bracelets Julie made if Sarah made s bracelets?
Answer:
Total no of bracelets = 5s+28
Step-by-step explanation:
Let Sarah made s bracelets.
Maria made 7 more than Sarah i.e. 7+s
Julie made 3 times as many as Maria i.e. 3(7+s)
Total no of bracelets made is equal to the sum of the bracelets made by Sarah, Maria and Julie.
Total = s+ 7 + s + 3(7+s)
= 2s+7+21+3s
=2s+3s+21+7
= 5s+28
So, there are (5s+28) bracelets.
What is the quotient of :

Step-by-step explanation:
Find two numbers which differ by 4 and whose products is 45
Answer:
5, 9
Step-by-step explanation:
let
x= first number
y = second number
x- y= 4( equation 1)
xy=45( equation 2)
From equation 1
x= 4+y( equation 3)
put equation 3 into equation 2
( 4+y)y=45
4y+y^2=45
( y-5)(y+9)=0
y=5,-9
Then put y=5 into equation 3
x=9
Answer:
-9 and 5
Step-by-step explanation:
Let's call the first number N1 and the second number N2.
So, let's call N1 the smaller number and N1=x
Let's call N2 the larger number and N2=x+4.
X(X+4)=45
x^2+4x=45
x^2+4x-45=0
(x+9)(x-5)=0
X=-9, X=5
solve (x^3-4x)(2x^2-3x)
Answer:
= x^2 ( 2x^3- 3x^2 - 8x + 12)
Step-by-step explanation:
(x^3-4x) (2x^2-3x)
= x^3(2x^2-3x) -4x(2x^2-3x)
= 2x^5-3x^4-8x^3+12x^2
= x^2 ( 2x^3- 3x^2 - 8x + 12)

Answer:
Width = 46 yards, Length=175 yards.
Step-by-step explanation:
Perimeter of rectangle = 2(length) +2(width)
We know that the length is 4width-9, so we can substitute that in for the length.
442= 2(4w-9)+2w, Next distribute
442=8w-18+2w, Now add like terms
442=10w-18, Move 18 to the other side
460=10w, solve for w
width= 46 yards.
Now we have 442=2(length)+2(46), subtract 92 to the left
350=2(length), divide by 2
Length= 175 yards.
Check your work with P=2(175)+w(46)
P=442 yards.
