you have $55 in your bank account each week you plan to deposit $7 from your allowance and $25 from your paycheck. the equation b = 55+(25+7)w gives me je amount b in your account after w weeks. how many weeks from now will you have $270 in your bank account?
Answer:
7 weeks
Step-by-step explanation:
Answer: The answer is 3.10
Step-by-step explanation: Fisrt of all you add 25+7 which gives you 32. Add 32 and 55, gives you 87. You need to figure out w and b is 270. So 270 divided by 87 is 3.10. So you need 3.10 weeks.
Please somebody help I have to redo 11th grade if i dont complete.. brainliest if you can help :(
Answer:
see below
Step-by-step explanation:
Assuming that
Point A is the same as point X
Point B is Point Y
Point C is Point Z
So we have
[tex]X=(1,5)\\\\Y=(2,2)\\\\Z=(6,1)[/tex]
the rule for a rotation of 180° is
For 180 degrees, the rule is (a, b) --------> (-a, -b)
so we have
[tex]X'=(-1,-5)\\\\Y'=(-2,-2)\\\\Z'=(6,1)[/tex]
the rule for reflection across the x axis
(a,b)----->(a,-b)
so we have
[tex]X''=(1,-5)\\\\Y''=(2,-2)\\\\Z''=(6,-1)[/tex]

Write an equation of the line passing through the point (5, 1) that is perpendicular to the line 5x+3y=15.
Answer:
y = [tex]\frac{3}{5}[/tex] x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
5x + 3y = 15 ( subtract 5x from both sides )
3y = - 5x + 15 ( divide all terms by 3 )
y = - [tex]\frac{5}{3}[/tex] x + 5 ← in slope- intercept form
with slope m = - [tex]\frac{5}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{5}{3} }[/tex] = [tex]\frac{3}{5}[/tex] , thus
y = [tex]\frac{3}{5}[/tex] x + c ← is the partial equation
To find c substitute (5, 1) into the partial equation
1 = 3 + c ⇒ c = 1 - 3 = - 2
y = [tex]\frac{3}{5}[/tex] x - 2 ← equation of perpendicular line
Here, we are required to Write an equation of the line passing through the point (5, 1) that is perpendicular to the line 5x+3y=15.
The equation of the line is; 3x - 5y = 10.
By comparison with the equation of a straight line: y = Mx + c
The equation 5x+3y=15 can be rewritten as ;
y = (-5/3)x + 5
Therefore, the slope of the equation is; (-5/3)
The product of the slope of two perpendicular lines is: -1.
therefore m1m2 = -1
Therefore; M2 = -1/(-5/3)
Therefore M2 = 3/5
The equation of the line passing through the point (5, 1) that has slope, M2 = 3/5 is;
3/5 = (y - 1)/(x - 5)
By Cross product;
3x - 15 = 5y -5
Therefore, the equation of the line is;
3x - 5y = 10.

What is the slope of the line through(-4,2) and (3,-3)?
Answer: [tex]-\frac{5}{7}[/tex]
Step-by-step explanation:
To find the slope of the line, you want to use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]m=\frac{-3-2}{3-(-4)} =\frac{-5}{7}[/tex]

Find the distance between each pair of points (-1,4) and (1,-1)
Answer:
d = [tex]\sqrt{29}[/tex]
Step-by-step explanation:
[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\d= \sqrt{(1-(-1))^2+(-1-4)^2} \\d= \sqrt{(2)^2+(-5)^2} \\d= \sqrt{4+25} \\d=\sqrt{29}[/tex]
The distance between each pair of points (-1,4) and (1,-1) is √29 units after using the distance formula.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is given that:
The distance between each pair of points (-1,4) and (1,-1)
Two points are (-1, 4) and (1, -1)
To find the distance between the above two points using the distance formula:
[tex]\rm d=\sqrt{(1-(-1))^2+(-1-4)^2}[/tex]
[tex]\rm d=\sqrt{(1+1)^2+(-1-4)^2}[/tex]
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division
d = √[(2)² + (-5)²]
d = √(4 + 25)
d = √29 units
Thus, the distance between each pair of points (-1,4) and (1,-1) is √29 units after using the distance formula.

Classrooms on one side of the drama building are all numbered with consecutive even integers. If the first room, the room with the smallest classroom number, on this side of the building is numbered y, write an expression in y for the sum of the
first four classroom numbers in a row. Then simplify this expression
The sum of the first four classroom numbers in a row is
Consecutive odd numbers are two apart (5, 7, 9, 11...). So given an odd integer, we can add 2 to get the next odd integer.
If the first odd integer is y, then the first 4 odd integers are
y
y+2
y+4
y+6
These add up to 4y+12
The sum of the first four classroom numbers in a row is 4y+12.
It is required to find the sum of the first four classroom numbers in a row.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
Since the smallest classroom number on the side of the building is numbered y and each consecutive even integers is separated by a difference of 2.
∴
y is the first class room.
y + 2 is the second class room.
y + 4 is the third class room.
y + 6 is the third class room.
The sum of the five consecutive class rooms are given as:
y + (y + 2) + (y+ 4) + (y + 6)
collecting alike terms we get
= y + y+ y+ y + 2 + 4 + 6
= 4y + 12
Therefore, the sum of the first four classroom numbers in a row is 4y+12.

Ryan is trying a low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels shown in the following compound inequality: 110 < 2x + 10 and 2x + 10 < 310 Solve for x in this inequality, and explain what the answer represents.
Answer:

Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.
So, Ryan's total carb intake must be between 50 and 150 carbs.
Step-by-step explanation:
So he wants to keep his consumption of carbs between the inequalities:
[tex]110<2x+10\text{ and } 2x+10<310[/tex]
So, let's solve both inequalities.
1)
[tex]110<2x+10[/tex]
Subtract 10 from both sides:
[tex]100<2x[/tex]
Divide both sides by 2:
[tex]50<x[/tex]
2)
[tex]2x+10<310[/tex]
Subtract 10 from both sides:
[tex]2x<300[/tex]
Divide both sides by 2:
[tex]x<150[/tex]
So, our inequality is now:
[tex]110<2x+10\text{ and } 2x+10<310[/tex]
Since we solved the equations:
[tex]50<x\text{ and } x<150[/tex]
Written as a compound inequality, this is:
[tex]50<x<150[/tex]
In other words, Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.
So, Ryan's total carb intake must be between 50 and 150 carbs.

Step-by-step explanation:
In order to find the value of ∠EFB here, we have to note our angle relationships.
We know that ∠CFE is already 90°. We also know that ∠CFA is 90°. Angle ∠AFB is inside ∠CFA. Since we know the measure of ∠AFB, we can find the measure of ∠BFC.
[tex]23 + x = 90\\\\x = 90-23\\\\x = 67[/tex]
Now that we know ∠CFE and ∠BFC, which together make ∠BFE, we can add these angles up.

Point B is between points A and C and points A, B, C are collinear so
AB + BC = AC
x-7 + 2x-2 = x + 13
3x - 9 = x + 13

The volume of the cell phone is 75 cubic centimeters. Write and solve an equation to find the height of the cell phone. Round your answer to the nearest tenth
Answer:
Equation: [tex]Height = \frac{75}{Area}[/tex]
Step-by-step explanation:
The question is incomplete as the dimension of the phone was not given.
However, the following explanation will guide you
Given
[tex]Volume = 75\ in^3[/tex]
Required
Determine the Height
Volume is calculated as thus;
[tex]Volume = Area * Height[/tex]
Substitute 75 for Volume
[tex]75= Area * Height[/tex]
Divide through by Area
[tex]Height = \frac{75}{Area}[/tex]
The above represent the equation to solve for Height
To solve for height, we need the dimension of the phone or the area.
Take for instance; the length and width of the phone is 5 by 5 inches;
The height would be:
[tex]Height = \frac{75}{5 * 5}[/tex]
[tex]Height = \frac{75}{25}[/tex]
[tex]Height = 3\ inches[/tex]
