Answer:
4x + 5y = - 23
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 )
rearrange 4y - 5x = 20 into this form
add 5x to both sides
4y = 5x + 20 ( divide all terms by 4 )
y = 
x + 5 ← in slope-intercept form
with slope m =
given a line with slope m then the slope of a line perpendicular to it is
= - 
, hence
= - 1 / = - 
y = - x + c ← is the partial equation
to find c substitute (- 2, - 3) into the partial equation
- 3 = 
+ c ⇒ c = - 
y = - x - ← in slope-intercept form
multiply all terms by 5
5y = - 4x - 23 ( add 4x to both sides )
4x + 5y = - 23 ← in standard form
Answer:
$42
Step-by-step explanation:
40% of $63 is $25.2
$63 - $25.2 = $37.8
How much your paying without tax 37.8
7% of $63 is $4.41.
$37.8 + $4.41 = $42.21
Rounded 42.21 = 42
Im not 100% sure about the rounding but I hope this helps!
The scale factor is About 1.077. It is important to know how to Find scale factor to understand how much smaller is the object from the other, it helps in Construction and architecture mainly but it helps with other things too.
Answer:
5 - q
Step-by-step explanation:
the term minus indicates a sign of subtraction, which looks like this
-
Therefore, the expression is 5 - q
There are 16 ounces in 1 pound, so to solve this, you would need to multiply the number 16 by 2.
16 * 2 = 32
Check work:
32 ÷ 2 = 16
<u>Your answer is 32, there are 32 ounces in 2 pounds.</u>
I hope this helps! :)
