morpeh [17]

Answer: (1,4)

Step-by-step explanation:

Given

Equation of line is 2y-3x=5

(-1,1) is the solution of the equation

Take x=1 and substitute it in the above equation

\Rightarrow 2y-3(1)=5\\\Rightarrow 2y=5+3\\\Rightarrow y=4

So, another pair of the solution is (1,4)

two angles are supplementary one angle measures 75% more than twice the measure of the other what are the measurement of the two
valkas [14]
Let's call the angles x and y. We know that supplementary angles must add to 180 degrees, so x+y=180.

Furthermore, we know that x is 75% more than 2y. We can write "75% more than" numerically as 1.75, so x = 1.75(2y).

We can simplify the second equation by multiplying 1.75 and 2 together to get x = 3.5y.

Now we can solve the system of equations by substitution by plugging 3.5y in for x in x+y=180.

(3.5y) + y = 180

Combine like terms.

4.5y = 180

Divide by 4.5

y = 40

Plug y = 40 in and solve for x.

x + 40 = 180

x = 140

The answer is 40 and 140. Hope this helps :)

Answer:

Congruent and isometries.

Step-by-step explanation:

Congruent meaning the shape is still the same size and shape

(which is true because translations and rotations don't change size or shape)

And isometries because it is one way of mapping points to  a different location.
