What is the slope of the graph of the line y=2x-3
Answer:
3/2 ??
Step-by-step explanation:
Hello there!
This equation is written in slope-intercept form (y=mx+b) which means it's easy to identify the slope.
In slope-intercept form, m is the slope.
Therefore, the slope of this line is 2.
Hope it helps.

Which graph represents the solution say to the system of equations
Answer:
Step-by-step explanation:
System of equations has been given as,
y = [tex]-\frac{1}{2}x+3[/tex] -------(1)
and y = [tex]\frac{1}{2}x-1[/tex] -------(2)
Slope-intercept form of the equation of a line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
By comparing this equation with the given lines,
y-intercepts of the given equations are 3 and -1
For solution of the systems,
[tex]-\frac{1}{2}x+3=\frac{1}{2}x-1[/tex]
[tex]\frac{1}{2}x+\frac{1}{2}x=3+1[/tex]
x = 4
From equation (2),
y = [tex]\frac{1}{2}(4)-1[/tex]
y = 1
Point of intersection of these lines is (4, 1).
Therefore, 4th graph (Extreme last from the left) will be the answer.

Which of the following polygons has five lines of symmetry?
O A. Equilateral triangle
OB. Regular heptagon
O C. Regular pentagon
O D. Square
Answer:
pentagon have 5 sides, 5 symmetry lines.
So your answer is Option C.
The polygon with five lines of symmetry is a regular pentagon.
Option B is the correct answer.
What are regular polygons?A regular polygon is a closed shape that has straight sides of equal length and interior angles of equal measure.
This means that all of the sides and angles of a regular polygon are congruent (i.e., have the same size).
We have,
A regular pentagon is a five-sided polygon where all sides and angles are equal. It has five lines of symmetry, which means it can be divided into five congruent parts through lines that reflect the polygon onto itself.
To see why a regular pentagon has five lines of symmetry, consider drawing lines from each vertex to the center of the pentagon.
These lines divide the pentagon into five isosceles triangles, each with two equal sides and two equal angles.
Each of these triangles has a line of symmetry that passes through its vertex opposite to the equal sides, and through the midpoint of the base.
Thus,
The regular pentagon has five lines of symmetry.

Ashton has an offer to buy an item with a sticker price of $4900 by paying
$140 a month for 48 months. Which of these groups of values plugged into
the TVM Solver of a graphing calculator will give him the correct answer for
the interest rate being offered?
A. N=4; 1% = ; PV=-4900; PMT=0; FV=140; P/Y=1; C/Y=12; PMT:END
B. N=4; 1% = ; PV=-4900; PMT=0; FV=6720; P/Y=1; C/Y=12; PMT:END
O C. N=4; 1% = ; PV=0; PMT=-4900; FV=6720; P/Y=1; C/Y=12; PMT:END
O D. N=4; 1% = ; PV=0; PMT=-4900; FV=140; P/Y=1; C/Y=12; PMT:END
We can plug them into the TVM Solver as follows:
N=4; 1% = ; PV=0; PMT=-4900; FV=6720; P/Y=1; C/Y=12; PMT:END
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To use the TVM (Time Value of Money) Solver of a graphing calculator to find the interest rate being offered, we need to input the correct values in the calculator.
PV = -$4900 (negative because it represents a payment)
PMT = $140
N = 48
FV = $0 (because we are assuming Ashton will pay off the item in full)
Using these values, we can plug them into the TVM Solver as follows:
N = 48; I/Y = 1%; PV = -$4900; PMT = $140; FV = $0; P/Y = 1; C/Y = 12; PMT: END
Thus,
We can solve for I/Y, which gives us an interest rate of approximately 13.41%.

Answer: 132
Step-by-step explanation:
Area of rectangle = length x width
(10 x 14. Add on the length of the triangle base)
Area of triangle = 1/2 base x height
(1/2*4 x 2. Notice the missing lengths on either side of 6 would be 2. 2 is also the height of the triangle)
In the figure, you have a rectangle with two equal triangles cut out at the bottom.
Find the area of the rectangle and subtract the area of the two triangles.
Area of rectangle 10x14= 140
Area of one triangle (1/2)4 x 2 = 4
Area of rectangle - two times area of triangle
140 - 2(4) =
140 -8 = 132
