$(x^2-3x)+(-2x^2+5x-3)=x^2-3x-2x^2+5x-3\\\\=(x^2-2x^2)+(-3x+5x)-3=-x^2+2x-3$

-x + 4y when x = -4/5 and y = 1/3

Usimov [2.4K]

we have the expression

$-x+4y$

Evaluate for x=-4/5 and y=1/3

substitute the values of x and y in the given expression

$\begin{gathered} -(-\frac{4}{5})+4(\frac{1}{3}) \\ \frac{4}{5}+\frac{4}{3} \\ \frac{3\cdot4+5\cdot4}{15} \\ \frac{32}{15} \end{gathered}$

the answer is 32/15

Answer:

Step-by-step explanation:

Pythagoras's theorem dictates that a squared + b squared = c squared when talking about sides on right angled triangles with a and b being flat sides and c being the hypotenuse which gives us the forumula below

3 squared + 4 squared = 25 route 25 = 5

Answer: 6

The sides are equal.

Thus

$3x-6=x+2\\2x=8\\x=4$

$JP=x+2=4+2=\boxed{6}$

Jackie follow the steps to elevate the expression 15 - (37 + 8) divide 3 37 + 8 = 45 45-15= 30 30 divided by 3 = 10 Mark looks a

Answer:

So, we conclude that Mark is right.

Step-by-step explanation:

If we have the following expression: 15 - (37 + 8) : 3.

We will first divide the value we get in parentheses and then subtract it.

Because sharing is an older mathematical operation than subtraction. Therefore, we get:

$15-(37+8):3=15-45:3=15-15=0$

So, we conclude that Mark is right.
