a) The cost price of the jacket after the decreased amount is $ 35
b) The cost price of 2 jackets is $ 70
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the price of the jacket after decrease be = A
Now , the equation will be
The original price of the jacket = $ 39.50
The amount decrease in the price of the jacket = $ 4.50
So , the cost price of the jacket after the decrease in price is = original price of the jacket - amount decrease in the price of the jacket
Substituting the values in the equation , we get
The cost price of the jacket = 39.50 - 4.50
The cost price of the jacket = $ 35.00
So , the cost price of the jacket is $ 35.00
Now , the cost price of 2 jackets is = 2 x sale price of the jacket
Substituting the values in the equation , we get
The cost price of 2 jackets is = 2 x 35
The cost price of 2 jackets is = $ 70
Therefore , The cost price of 2 jackets is $ 70
Hence ,
a) The cost price of the jacket after the decreased amount is $ 35
b) The cost price of 2 jackets is $ 70

To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.
To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction x 2 minus x 1 Over y 2 minus y 1 EndFraction.
To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.
To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction x 2 minus x 1 Over y 2 minus y 1 EndFraction.
The accurate statement which explains how to determine the slope (m) and y-intercept (b) of a line on a coordinate plane that goes through two points is:
C. To determine the y-intercept, move from the origin vertically to the graphed line. To find the slope, you will use two ordered pairs on the line and substitute into the equation .
Recall:
The y-intercept is the point at which the graphed line intercepts the y-axis (vertical axis). The y-intercept is the value of y here.
Slope (m) =
You can simply find the y-intercept on a coordinate plane like the one given in the image attached below.
To do this, from the point of origin (0), you have to move towards the graphed line, that's vertically upwards, to the point where the line crosses the vertical axis.
The y-intercept in the graph shown in the image = 2.
To find the slope, use two ordered pairs on the line, i.e., (0, 2) and (1, 5). (see attached image.)
Thus:
Therefore, the accurate statement which explains how to determine the slope (m) and y-intercept (b) of a line on a coordinate plane that goes through two points is:
C. To determine the y-intercept, move from the origin vertically to the graphed line. To find the slope, you will use two ordered pairs on the line and substitute into the equation .

Answer:
6 and 2/3
Step-by-step explanation:
56 and 2/3 divided by 8 1/2
Rewrite the mixed numbers as a fractions greater than 1.
56 and 2/3 divided by 8 and 1/2 = 170/3 divided by 17/2.
Rewrite the problem as a multiplication using the reciprocal of the divisor.
170/3 divided by 17/2 = 170/3 x 2/17
= 170 x 2
3x17
cross out 170 to 10. Then cross out 17 to 1.
= 20/3, or 6 an 2/3
