The y - intercept of the line is -21 .
Slope - inercept form of equation of line :
y = m x + c
where m is the slope and c is the y - intercept of the line .
Writing equation in slope - intercept form :
( - 5 - 3 ) / ( - 4 + 6 ) = ( y - 3 ) /( x + 6 )
( -8 ) / ( 2 ) = ( y - 3 ) /( x + 6 )
- 4 ( x + 6 ) = y - 3
- 4 x - 24 = y - 3
y = - 4 x - 21
Hence , the y - intercept of the line is -21 .

Answer:
98.3 seconds
Step-by-step explanation:
If you use stoichometry you can convert your units
9.83 seconds
over 100 meters a kilometer is 1000 meters so
9.83/100 *10 because what you do to denominator needs to happen to numerator
98.3 seconds
over 1 kilometer
it take the sprinter 98.3 seconds to run a kilometer and one way to check is well a kilo is a longer distance so logically the time it takes them has to be higher cause they cannot run a kilo faster than they run 1/10 of it
14.04 US dollars or 14 4/10
Answer:
Part A:
(2x+7)(5x+9)
=(2x+7)(5x+9)
=(2x)(5x)+(2x)(9)+(7)(5x)+(7)(9)
=10x2+18x+35x+63
=10x2+53x+63
A)
The formula for determining the area of a rectangle is given as
Area = length × width
Given that the length and width are (2x + 6) units and (5x + 3) units, the expression for the area is
(2x + 6)(5x + 3) = 10x² + 6x + 30x + 18
Area = 10x² + 36x + 18
B)
The degree is 2 because the highest power of the terms is 2. It is classified as a trinomial because it has 3 terms.
C) it is closed under multiplication. the exponents in the polynomials are whole numbers(2 and 1). The whole numbers are closed under addition, which means that the new exponents formed are also whole numbers. The exponents were whole numbers before multiplication and doesn't change after multiplication.
