Can someone help me with this??
Answer:
Step-by-step explanation:
Let the number of weeks = x
4*2.54 + 4x = growth for A
10*2.54 + 1*x= growth for B
So they will be the same when the 2 left sides are equated.
10.16 + 4x = 25.5 + x Subtract 10.16 from both sides
4x =25.5-10.16 + x Combine
4x = 15.34 + x Subtract x from both sides.
4x-x = 15.34
3x = 15.34 Divide by 3
x = 15.34/3
x = 5.11
So the answer is just a little over 5 weeks.

A line passes through the point (-6,4) and has a slope of 3/2. Write an equation in point slope form for this line.
Answer:
y-4=3/2(x+4)
Step-by-step explanation:
If you plug the numbers into the equation (y-y1=m(x-x1)), you get y-4=3/2(x+4).
Answer: y=3/2x+13
Step-by-step explanation: y-4=3/2(x-(-6))
y-4=3/2x+9
y=3/2x+13

The sum of the cube of a number and two times the number
Answer:
x^3+x×2
I got this : ) I hope it helped
The expression x³ + 2x represents the sum of the cube of a number and two times the number "x."
"the sum of the cube of a number and two times the number."
Let "x" represent the unknown number.
Express the given in algebra form as x³ + 2x.
To calculate the value of this expression for a specific value of "x," substitute the value of "x" into the expression.
Cube the number by raising it to the power of 3 (x³).
Multiply the number by 2 (2x).
Add the results
expression x³ + 2x represents the sum.

I have to do step by step why the answer of (5x - 1) (5x - 1) is 25x^2 - 10x + 1.
How do i do it?
(5x - 1) (5x - 1)
Ans: 25x^2 - 10x + 1
Answer:
Step-by-step explanation:
(5x - 1) (5x - 1)
= [tex](5x - 1)^{2}[/tex]
Using laws of exponents,
[tex](a - b)^{2} = a^{2} - 2ab + b^{2}[/tex]
here, a = 5x, b = 1
so it becomes,
[tex]5x^{2}[/tex] - 2 × 5x × 1 + [tex]1^{2}[/tex]
[tex]25x^{2}[/tex] - 10x + 1

The measure of an angle is 35.4°. What is the measure of its supplementary angle?
Answer:
144.6°
Step-by-step explanation:
180-35.4
144.6°
Answer:
144.6
Step-by-step explanation:
Supplementary angles add to 180
Let x be the unknown angle
x + 35.4 = 180
Subtract 35.4 from each side
x = 180-35.4
x =144.6
simplify 1/2 +1/4 - 1/6
Answer:
look for the LCM of all the denominators, devide the denominators by the LCM and add the numerators( don't forget the signs ), then add and subtract your answers ( by this time the LCM becomes the denominator and the answer from th subtraction and addition of the numerators becomes the present numerator ), then reduce to lowest term the answer gotten

If Isaac uses a coupon entitling him to a 25% discount off the purchase price before tax, how much will his bill be? Assume that a 7% sales tax is applied to the discounted price. Using words, explain how you found the discounted price.
Answer:
hope it helps...
Step-by-step explanation:
25/100 x 79
= 19.75
= 79 - 19.75
= $59.25 (before tax)
7/100 x 59.25
= 414.75/100
= 4.15
= 59.25 + 4.15
= $63.4 (after adding tax)
First we have to take out the percentage of discount and minus it from the total cost . To find the discounted price with tax, we have to take out the percentage of the tax from the discounted amount and add it to the discounted amount to get the total cost.

Which of the following statement is true?
3 / 12 is the same as 3 ÷ 12
3/12 is the same as 12 ÷ 3
3 ÷ 12 is the same as 12/3
12/3 is the same as 3/12
Answer:
3/12 is the same as 3 divided by 12
Suppose b is an integer. If b mod 12 = 5, what is 8b mod 12? In other words, if division of b by 12 gives a remainder of 5, what is the remainder when 8b is divided by 12
Answer:
8 b mod 12 is equal to 4.
Step-by-step explanation:
Use Dividend = Divisor × Quotient + Remainder
As b mod 12 = 5 (that is division of b by 12 gives a remainder of 5)
[tex]b=12k+5[/tex]
Here, k is any integer.
Multiply both sides of [tex]b=12k+5[/tex] by 8
[tex]8b=8(12k+5)\\8b=8(12k)+40[/tex]
write 40 in terms of 12
[tex]40=36+4=12(3)+4[/tex]
[tex]8b=8(12k)+12(3)+4\\8b=12(8k+3)+4[/tex]
Therefore,
8 b mod 12 is equal to 4.

use matrices to determine the coordinates of the vertices of the translated figure. Triangle DEF with vertex matrix [7 -9 -1 -7 -3 -7] translated 1 unites left and 4 units down.
Answer:
(6, -11), (-10, -7) and (-2, -11)
Step-by-step explanation:
Coordinates of a triangle are represented in the form of a matrix as,
[tex]\begin{bmatrix}x_1 & x_2 & x_3\\ y_1 & y_2 & y_3\end{bmatrix}[/tex]
If the given triangle is shifted by 1 unit left and 4 units down,
Translation of vertices in the matrix form will be,
[tex]\begin{bmatrix}x_1 & x_2 & x_3\\ y_1 & y_2 & y_3\end{bmatrix}+\begin{bmatrix}-1 & -1 & -1\\ -4 & -4 & -4\end{bmatrix}[/tex]
For a triangle having vertices (7, -7), (-9, -3) and (-1, -7) when shifted 1 units left and 4 units down will be,
[tex]\begin{bmatrix}7 & -9 & -1\\ -7 & -3 & -7\end{bmatrix}+\begin{bmatrix}-1 & -1 & -1\\ -4 & -4 & -4\end{bmatrix}[/tex]
= [tex]\begin{bmatrix}7-1 & -9-1 & -1-1\\ -7-4 & -3-4 & -7-4\end{bmatrix}[/tex]
= [tex]\begin{bmatrix}6 & -10 & -2\\ -11 & -7 & -11\end{bmatrix}[/tex]
Coordinates of the triangle after the translation will be,
(6, -11), (-10, -7) and (-2, -11)

What is the greatest number of rìght angles that a triangle can contain?
Answer:
1
Step-by-step explanation:
If there are 2 or more right angles in a triangle, it is impossible to connect without a fourth side, making it a square. There can only be 1 right angle in a triangle
Answer:
There can Only be 1 Right angle in a Triangle!
Step-by-step explanation:
Triangles have 180 degrees in total, If You had Two Right Angles, Then it would equal 180, since there is three angles,three sides and etc on a triangle that won't work. In a Triangle you could have 1 right angle and Two 45 degree angles to get your total of 180 degrees and a complete Triangle!!
