The slope is 9 and the y-intercept is -2.
Answer:
The expression for the total amount of Jamal earned is $ (14 y + 55)
Step-by-step explanation:
Given as :
The bonus amount earn by Jamal = $ 55
According to question
On Thursday
∵ For 1 hour of work , Jamal earn y dollars
∴ For 9 hours of work , Jamal will earn 9 × y = 9 y dollars
On Friday
∵ For 1 hour of work , Jamal earn y dollars
∴ For 5 hours of work , Jamal will earn 5 × y = 5 y dollars
So, The total earning on both days of his work = 9 y + 5 y = 14 y dollars
Since Jamal also earn bonus of $ 55
So, Total earning of Jamal including bonus = 14 y + $ 55
Hence The expression for the total amount of Jamal earned is $ (14 y + 55) Answer
Answer:
The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
x i the height of a large block.
y is the height of a small block.
Taylor uses 4 large blocks and 2 small blocks to make a tower 63.8 inches tall.
This means that:

Simplifying by 2:

So

Natsumi uses 9 large blocks and 4 small blocks to make a tower 139.8 inches tall.
This means that:

Since 




The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

Step-by-step explanation:
Many calculators can perform polar ⇔ rectangular conversion. Attached is the result from one of them. Of course, you can also program a spreadsheet to do it. (The ATAN2( ) function is useful for finding the correct angle.)
If you want to do these calculations by hand, the conversion is ...
<r, θ> ⇒ <r·cos(θ), r·sin(θ)>
In the attached, the rectangular coordinates are shown as complex numbers. The imaginary component is the y-component of the vector.
