The graph below shows how much money you have in savings each week. Use
this graph to answer questions (a – g).
a. According to the graph how much money did you start with in your savings?
b. How much money will you have after 5 weeks of saving?
Answer:
Step-by-step explanation:
a). Since starting point of the line is (0, 50),
Therefore, I started with the saving of $50.
b). Since endpoint of the segment is (5, 175),
Money with me after 5 weeks will be $175.
c). Let the equation of the line given in the graph is,
y - y' = m(x - x')
Where (x', y') is a point lying on the graph.
And 'm' is the slope of the line.
Slope of the line = [tex]\frac{175-50}{5-0}[/tex]
m = [tex]\frac{125}{5}[/tex]
m = 25
Since, the line passes through (0, 50),
y - 50 = 25(x - 0)
y = 25x + 50
y = 25x + 50
For x = 6,
y = 25×6 + 50 = 200
For x = 7,
y = 25×7 + 50 = 225
For x = 8,
y = 25×8 + 50 =250
d). For x = 10 weeks,
y = 25×10 + 50 = $300
e). For x = 15 weeks
y = 25×15 + 50 = $425
f). For x = 50 weeks,
y = 25×50 + 50 = $1300
g). Equation of the line is,
y = 25x + 50

Help someone please I need this one correct to get a good grade
1) The square root of 8 is the least, since 3^2 equals 9, and 8 is less than 9, so its the least.
2) Then the cube root of 27, because 3 cubed is equal to 27
3) Finally, pi is the largest since it equals 3.142.
Good luck with your grades.

4.) Trapezoids ABCD and EFGH are congruent. What is the length of side FG?
a. 9 m
b. 12 m
C. 15 m
Answer:
C. 15m
Step-by-step explanation:
if ABCD and EFGH are congruent that means that they are equivalent to each other. If side FG is the base of that trapizoid, and side CD is the base with the measurement of 15m, then we are left to believe that side FG is 15m

Label each of the following as true, false, or open.
a. –4(5x) = 12
b. 4 x 6 = 24
c. a + 4 = 6, when a = 2.
d. 4x = 19, when x equals 5.
Answer:
a. –4(5x) = 12; OPEN
b. 4 x 6 = 24; TRUE
c. a + 4 = 6, when a = 2; TRUE
d. 4x = 19, when x equals 5; FALSE
Step-by-step explanation:
a. –4(5x) = 12 [-20x = 12 {Divide -20 from both sides} x = -0.6 So, if x is = -0.6, then it is true, so OPEN.
b. 4 x 6 = 24 [4 x 6 = 24 so TRUE]
c. a + 4 = 6, when a = 2. (Plug 2 in for a) 2 + 4 = 6; 6 = 6; TRUE
d. 4x = 19, when x equals 5. (Plug 5 in for x) 4(5) = 19; 20 is not = 19; FALSE

An axiom is a basic assumption about a mathematical situation. There are five axioms that form the basis for Euclidean geometry. List the five axioms.
The five axioms are:
Things which are equal to the same thing are also equal to one another.
If equals be added to equals, the wholes are equal.
If equals be subtracted from equals, the remainders are equal.
Things which coincide with one another are equal to one another.
The whole is greater than the part.
Answer:
AXIOMS AND POSTULATES OF EUCLID
Step-by-step explanation:
AXIOMS
Things which are equal to the same thing are also equal to one another.
If equals be added to equals, the wholes are equal.
If equals be subtracted from equals, the remainders are equal.
Things which coincide with one another are equal to one another.
The whole is greater than the part.
POSTULATES
To draw a straight line from any point to any point.
To produce a finite straight line continuously in a straight line.
To describe a circle with any center and distance.
That all right angles are equal to one another.
That if a straight line falling on two straight lines makes the interior angles on the same side less than two right angles, the straight lines, if produced indefinitely, will meet on that side on which the angles are less that two right angles.*

Solve the inequality. | 2x + 3 | < 7
please show all the work
Answer:
[tex]-5<x<2[/tex]
Step-by-step explanation:
We have the inequality:
[tex]|2x+3|<7[/tex]
Use the definition of absolute value:
[tex](2x+3)<7\text{ or } -(2x+3)<7[/tex]
Let's evaluate each case individually.
Case 1)
We have:
[tex]2x+3<7[/tex]
Subtract 3 from both sides:
[tex]2x<4[/tex]
Divide both sides by 2:
[tex]x<2\\[/tex]
Case 2)
We have:
[tex]-(2x+3)<7[/tex]
Divide both sides by -1. Since we're dividing by a negative, flip our sign:
[tex]2x+3<-7[/tex]
Subtract 3 from both sides:
[tex]2x<-10[/tex]
Divide both sides by 2:
[tex]x<-5[/tex]
So, our solutions are, from least to greatest:
[tex]\{x|-5, 2\}[/tex]
We can see that our inequality is a greater than.
Remember, when dealing with absolute value:
When our sign is greater than (or equal to), our solution is an "or" inequality with our solutions being all values less than our lesser solution or all values greater than our greater solution.
When our sign is less than (or equal to), our solution is an "and" inequality with our solution being between our two solutions.
Since our inequality is a less than, our solution is all the values between our lesser solution and our greater solution.
Our lesser solution is -5. Our greater solution is 2.
So, the solution to the inequality is all values between -5 and 2. As a compound inequality, this is:
[tex]-5<x<2[/tex]

I will give a brilliant!
Answer:
A
Step-by-step explanation:
the absolute value of a negative number is positive because the absolute value of a number is the distance from 0 on the number line, and distance is positive. -1 is negative, and positive numbers are larger than negative numbers, so |-5/8| is automatically larger.

A square room in Denise's house measures 15 feet by 15 feet. Find the length of the diagonal of the room, rounded to the nearest tenth
The length of the diagonal of the room is approximately 21.2 feet when rounded to the nearest tenth.
Given information:
A square room in Denise's house measures 15 feet by 15 feet.
Since the room is square, the diagonal forms the hypotenuse of a right triangle whose legs are the sides of the square.
Each side of the square measures 15 feet, so we have:
d² = 15² + 15²
Simplifying:
d² = 2(15²)
d² = 2(225)
d² = 450
Taking the square root of both sides:
d ≈ 21.2

4(x + 2) − 2x = 4(x − 3) please show work
Answer:
x = 20
Step-by-step explanation:
PEMDAS
P = parenthasees
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
this is the order
so first
4x + 8 -2x = 4x - 12
No exponents
no Multiplication
No division
Addition
So for this, we have to subtract the 4x on both sides to get
x + 8 - 2x = -12
then do -8
x - 2x = -20
then
-x = -20
x = 20
