Answer:

The answer is that x = 6 and y = -6

Step-by-step explanation:

In order to find these values, we can use elimination. To do so, we multiply the first equation by 2 and then add the equations together.

4x + 8y = -24

-4x - 2y = -12

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

6y = -36

y = -6

Now that we have this value, we can plug the value into one of the originals and find x.

2x + 4y = -12

2x + 4(-6) = -12

2x - 24 = -12

2x = 12

x = 6

Evaluate b²c¹ for b=8 c=-4

AVprozaik [17]

Answer:

The answer is -256.

Step-by-step explanation:

You have to substitute the value of b and c into the expression :

${b}^{2} {c}^{1}$

Let b = 8,

Let c = -4,

${8}^{2} \times { - 4}^{1}$

$= 64 \times - 4$

$= - 256$

formula is y2-y1 / x2-x1

-1.5 - (-3) / 0 - (-6)

-1.5 - (-3) = 1.5

0 - (-6) = 6

1.5 / 6 = 0.25

Determine a scalar c so that the angle between a = i + cj and b = i + j is 45°.

Marina CMI [18]

Answer:

c=0

Step-by-step explanation:

ATQ a.b=|a||b|sin(45)

1+c=sqrt(1+c^2)*sqrt(2)*1/sqrt(2)

1+c=sqrt(1+c^2)

(1+c)^2=(1+c^2)

2c=0, c=0
