#5 please help me solve this

x intercept = -7/2

y intercept = 21/5

Step-by-step explanation:

-6x +5y = 21

To find the x intercept, set y=0 and solve for x

-6x +5(0) =21

-6x =21

Divide each side by -6

-6x/-6 = 21/-6

x = -21/6 = -7/2

To find the y intercept, set x=0 and solve for y

-6(0) +5y = 21

5y =21

Divide each side by 5

5y/5 =21/5

y = 21/5

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
