A. slope is rise/run. can count up 3 right 2. slope = 3/2
also by slope formula m = (y - y1)/(x - x1)

B. y-intercept is the y coordinate where the line crosses the y-axis.
See that it is at y = -4 on the graph?
To use the slope.. go backwards from the closest point (4,2) down 2 left 3 gets you to the next point (2,-1) then go down 2 left 3 again to get to y-intercept (0, -4)

C. y = (3/2)x - 4

How you get it is by putting in the values into the standard equation for a line; y = mx + b
m is slope and b is y-intercept.

angle 3 and angle 4 form a linear pair. the measure of angle 3 is four more than three times the measure of angle 4. find the me
lisabon 2012 [21]
Since angles 3 and 4 form a linear pair, the sum of the measures of their angles must add up to 180. 

We can define angle 3 as x, and angle 4 as (180-x). 

x = 3 ( 180 - x ) + 4.

Solving for x, we get x=138. This is angle 3. Angle 4 is 180-138, so angle 4 is 42.

6) BRAINLIEST & 10 + POINTS!
MA_775_DIABLO [31]

Answer:

the height of the building is approximately 134 yards

Step-by-step explanation:

Recall that i order to use the arc-length formula:

arc\,\,length=R\,\theta

we know the radius R, but the angle \theta must be given in radians. Then we convert 4.5^o to radians, and then use 1700 yards as the radius in the formula.

4.5^o*\frac{\pi}{180} =0.07854

Therefore, the arc length formula would render:

arc\,\,length=R\,\theta\\arc\,\,length=1700\,(0.07854)=133.518\, yards

which rounded to the nearest yard becomes: 134 yards

solve the given matrix equation for X. Simplify your answers as much as possible. (In the words of Albert Einstein, "Everything
vova2212 [387]

a.

XA^{-1}=A^3

(XA^{-1})A=A^3A

X(A^{-1}A)=A^4

X=A^4

b.

AXB=(BA)^2

A^{-1}(AXB)B^{-1}=A^{-1}(BA)^2B^{-1}

(A^{-1}A)X(BB^{-1})=A^{-1}(BA)^2B^{-1}

X=A^{-1}(BA)^2B^{-1}

c.

(A^{-1}X)^{-1}=(AB^{-1})^{-1}(AB^2)

X^{-1}A=(BA^{-1})(AB^2)

X^{-1}A=B(A^{-1}A)B^2

X^{-1}A=B^3

(XX^{-1})A=XB^3

XB^3=A

X(B^3(B^3)^{-1})=A(B^3)^{-1}

X=A(B^3)^{-1}

d. Not totally sure what the equation is supposed to be, but I guess it's

ABXA^{-1}B^{-1}=A

ABX(BA)^{-1}=A

((AB)^{-1}(AB))X((BA)^{-1}(BA))=(AB)^{-1}A(BA)

X=(AB)^{-1}A(BA)

X=(B^{-1}A^{-1})A(BA)

X=B^{-1}(A^{-1}A)(BA)

X=(B^{-1}B)A

X=A

What is the solution to this equation?
tensa zangetsu [6.8K]

Answer:

Think

Step-by-step explanation:

4x - 6 + 2x = 18

You are solving for x so obviously you have to have your x variable on one side of the equal sign by itself.

So how do you do that? Combine the same calues together and seperate the rest

4x + 2x = 6x

6x = 18 + 6

6x = 24

x = 3

Practice practice practice. Simple stuff. You got this!
