Can someone help me? find the solution for this system of equation ​
puteri [66]

Answer:

(5/6, 8/5)

Step-by-step explanation:

We multiply the second equation by 2, and then add the equations together.

12x+15y=34

-12x+10y=6

------------------

25y=40

We divide by 25 on both sides, and get that y = 8/5. We substitute y into either of the equations.

-6x +5(8/5)=3

Do the multiplication.

-6x+8=3

Subtract 8 from both sides.

-6x=-5

Divide by -6 on both sides.

x=5/6.

What is the volume of the rectangle pyramid show below?
Maksim231197 [3]

Answer:

Option (3)

Step-by-step explanation:

Volume of a rectangle = \frac{1}{3}(\text{Area of the rectangular base)(\text{Height})}

Area of the rectangular base = Length × Width

                                                = 7 × 8

                                                = 56 square in.

Height of the pyramid = 9 in.

Therefore, Volume of the given pyramid = \frac{1}{3}(56)(9)

                                                                    = 168 cubic in.

Option (3) will be the correct option.

identify an equation in point-intercept form for the line parallel to y = -3x + 7 that passes through (2, -4)
Natali5045456 [20]
Let's organize.
The question says to <u>identify</u> an <u>equation in point-intercept form</u> for the <u>line</u> that's <u>parallel</u> to y = -3x + 7 that <u>passes through</u><u /> (2, -4).

If you need to find an equation in point-intercept form that passes through a point, you will substitute the coordinate in this formula:

-> y - yo = m (x - xo)

Where:

(2, -4) -> xo = 2 ; yo = -4
m = Slope

You don't have the slope, but you have the information that the line is <u>parallel</u> to <u />y = -3x + 7. Then you need to know that to a line be <u>parallel to another</u> the Slopes of each other must be equal, mr = ms.

Let's find the slope of the equation given, it is in a slope-intercept form, so:

y = mx + b

R: y = -3x + 7     // I will call this one R line, and the other S.

mr = -3

If the mr = ms, and mr = -3, then the ms = -3 too.

S: y - yo = ms (x - xo) // (2, -4) & ms = -3

-> 
y - (-4) = -3 (x - 2)
-> S: y + 4 = -3 (x - 2) -> This is the point-slope form.


-> 
y = -3x + 6 - 4
-> S: y = -3x - 2 -> This is the slope-intercept form.

I didn't understand what is the point-intercept form that the question requests, but by logic, i think that's the point-slope form.

Answer: The equation in point-intercept form is: y + 4 = -3 (x - 2).
