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.
Answer:
Option (3)
Step-by-step explanation:
Volume of a rectangle = 
Area of the rectangular base = Length × Width
= 7 × 8
= 56 square in.
Height of the pyramid = 9 in.
Therefore, Volume of the given pyramid = 
= 168 cubic in.
Option (3) will be the correct option.
It'd be 54. Its flipping the numbers, adding two, flipping again, repeat.
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).
