3x-(2x-1)=7x-(3*5x)+(-x+24)

Paraphin [41]

Answer:

$\boxed{\boxed{\sf x=\frac{23}{10}}\: \sf or \:\boxed{x=2.3}}$

_________________

$\boxed{\sf Step\: By\:Step:- }$

$\sf 3x-\left(2x-1\right)=7x-\left(3\times \:5x\right)+\left(-x+24\right)$

<u>Remove the parentheses:</u>

$\to\sf 3x-\left(2x-1\right)=7x-3\times \:5x-x+24$

<u>Combine like terms:</u>

$\sf ^*7x-x=6x$

$\to\sf 3x-\left(2x-1\right)=6x-3\times \:5x+24$

<u>Multiply 3 and 5x = 15x:-</u>

$\to\sf 3x-\left(2x-1\right)=6x-15x+24$

<u>Combine like terms:</u>

$\sf ^*6x-15x=-9x$

$\to\sf 3x-\left(2x-1\right)=-9x+24$

<u>Expand: 3x-(2x-1)= x+1</u>

$\to\sf x+1=-9x+24$

<u>Subtract 1 from both sides:</u>

$\to\sf x+1-1=-9x+24-1$

$\to\sf x=-9x+23$

<u>Add 9x to both sides:</u>

$\to\sf x+9x=-9x+23+9x$

$\to\sf 10x=23$

<u>Divide both sides by 10:</u>

$\to\sf \cfrac{10x}{10}=\cfrac{23}{10}$

$\to\sf x=\cfrac{23}{10}$

X1 + x2 / 2 , y1 + y2 / 2

8 + x2 /2 = 6

So x is 4

9 + y2 /2 = 6

So y is 3.

Answer is B ( 4, 3)

Please Mark Brainliest if it helped

how long is |MN| when you measure it and do you know anything about the length of |NO| and |OP|?

assuming |MN|= 7.7 ; |NO|= 4.7 ; |MO|= 5.5:

o²= m²+n²

= 4.7²+5.5²

=52.34

o=V52.34

≈7.23

In which direction does the graph of the function shown below open?

sp2606 [1]

Answer:

D. Up

Step-by-step explanation:

When a parabola has the form $y=ax^2+bx+c$ , It is vertical (opens up or down).

Because the variable "x" is squared.

If "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.

In this case you have the quadratic function:

$f(x) = 2x^2+5x-4$

Which can be rewritten as:

$y = 2x^2+5x-4$

Therefore, it is vertical, because it has the form: $y=ax^2+bx+c$

You can observe that the value of "a" is:

$a=2$

Then, since "a" is positive, the parabola opens up.
