Answer:
4th option
Step-by-step explanation:
The points R', S', T', U' are obtained by a reflection in the line y = - 3
This is a horizontal line passing through all points with a y- coordinate of - 3
RSTU and R'S'T'U' are equidistant from this line
Answer:
Part 1) The equation that can be used is 1.8x-10=-4
Part 2) The input or x-value is x=10/3
Step-by-step explanation:
we have
f(x)=1.8x-10
g(x)=-4
To find the solution of the system of equations equate f(x) and g(x)
f(x)=g(x)
substitute
1.8x-10=-4 -----> equation that can be used to find the input value at which f (x ) = g (x )
Solve for x
Adds 10 both sides
1.8x=-4+10
1.8x=6
Divide by 1.8 both sides
x=6/1.8
Remember that
1.8=18/10
substitute
x=6/(18/10)
x=60/18
Simplify
x=10/3
Answer:
where is the rest of the question
Step-by-step explanation:
Answer:
x= 5 1/3
Step-by-step explanation:
l3x-5l=11
3x-5=11
+5 +5
3x=16
/3 /3
x=5 1/3
I line that is perpendicular is a line with reversed slopes like 2/1 is perpendicular to -1/2. So find the slope by getting the y by itself and reverse it. Remember to switch the signs too! P.S. if you don't know how to get the y by itself just take and subtract 3x from -5y and -4 then divide by 5. Hope I helped!
