Solve the system of equation Y=4x-11 Y=x+13 X= Y =

Phoenix [80]

Answer:

(8,21)

Step-by-step explanation:

Since both equations equal y, set both equaitions equal to each other

and solve for x

4x-11=x+13 , subtract x from both sides

3x-11=13, add eleven to both sides

3x=24, divide both sides by 3 to get x alone

x=8

Substitute x=8 into either equation to solve for y

y=4(8)-11

y=32-11

y=21

A number cube with faces labeled 1 to 8 is rolled once. The number rolled will be recorded as the outcome. Consider the followin

andrew11 [14]

Answer to A:

50%

Explanation for A:

We're looking for how many numbers are odd, so theres 1, 3, 5 ,7, four numbers.

We have a total of 8 numbers.

$\frac{4}{8} = 0.5$

To make any number a percent we move the point over to the right by two, which makes our final answer 50%

Answer to B:

37.5%

Explanation for B:

If the number is less than four, that means we need to find if it will roll the first three numbers. We, once again, have eight total possibilities

$\frac{3}{8} = 0.375$

0.375 can be turned into our final answer, 37.5%

Write the standard form of the equation of the circle below.

sergeinik [125]

Answer:

$x^2+(y+1)^2=2$

Step-by-step explanation:

We use the formula for a circle with center at (0, -1), that goes through the (x, y) point (-1, -2):

$(x-0)^2 + (y-(-1))^2 = R^2\\Using \,\,\,point\,\,\,(-1, -2)\\(-1-0)^2+ (-2+1)^2 = 1 + 1 = 2 = R^2$

Therefore, the equation of this circle can be written as:

$x^2+(y+1)^2=2$
