Answer:

x = -9

y = 8

Step-by-step explanation:

(using substitution)

4x-y = -44

4x + 44 = y

substitute (4x+44) as y in the other equation

2x + 3(4x+44) = 6

2x+12x+132 = 6

14x = -126

x = -9

then plug -9 as x into one of the equations to find y

4(-9) - y = -44

-36-y=-44

-y=-8

y=8

then check the answer by plugging in the values of x and y (-9 and 8) for x and y in one of the equations

4(-9) - (8) = -44

you get: -44 = -44, which is true, so the x and y values are correct

Answer:

x=−9 and y=8

Step-by-step explanation:

Let's solve your system by elimination.

2x+3y=6;4x−y=−44

Multiply the first equation by -2,and multiply the second equation by 1.

−2(2x+3y=6)

1(4x−y=−44)

Becomes:

−4x−6y=−12

4x−y=−44

Add these equations to eliminate x:

−7y=−56

Then solve−7y=−56for y:

−7y=−56

-7y/-7 = = -56/-7

(Divide both sides by -7)

y=8

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

2x+3y=6

Substitute8 for y in 2x+3y=6:

2x+(3)(8)=6

2x+24=6(Simplify both sides of the equation)

2x+24+−24=6+−24(Add -24 to both sides)

2x=−18

2x/2 = -18/2 (Divide both sides by 2)

x=−9

<u>Answer:</u>

x=−9 and y=8

Find the ratio AP/PB for 100 points ASAP
shtirl [24]

Answer:

\frac{1}{2}

Step-by-step explanation:

To find the ratio of AP/PB, find the distance between A and P, then P and B.

Distance between A(-5, 6) and P(1, 4):

AP = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let,

A(-5, 6) = (x_1, y_1)

P(1, 4) = (x_2, y_2)

AP = \sqrt{(1 -(-5))^2 + (4 - 6)^2}

AP = \sqrt{(6)^2 + (-2)^2}

AP = \sqrt{36 + 4} = \sqrt{40}

Distance between P(-1, 2) and B(1, -2):

PB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let,

P(1, 4) = (x_1, y_1)

B(13, 0) = (x_2, y_2)

PB = \sqrt{(13 - 1)^2 + (0 - 4)^2}

PB = \sqrt{(12)^2 + (-4)^2}

PB = \sqrt{144 + 16} = \sqrt{160}

\frac{AP}{PB} = \frac{\sqrt{40}}{\sqrt{160}}

= \frac{\sqrt{40}}{2\sqrt{40}}

= \frac{1}{2}

Factor completely<br> 9-6a-24a^2
Natasha_Volkova [10]
-24a²- 6a +9 = - 3(8a² +6a - 9)

8a² +6a - 9 =0

x=(-b +/-√(b² - 4ac))/2a
x = (-6 +/-√(36+4*8*9)  /(2*8) = (-6 +/-√(324)  /16 =  (-6 +/-18)/16
x1 =  (-6 +18)/16 = 0.75
x2 =  (-6 -18)/16 = - 1.5

-24a²- 6a +9 = - 3(8a² +6a - 9) = -3(a - 0.75)(a + 1.5)

Answer:

A

Step-by-step explanation: im not extremely sure about this one though but the x coordinate is nine away from every coordinate of defc and the way it goes left means that the x is negative, the y coordinates of defc prime is positive because it moves up from defc. hope this helps
