Answer:

y = -x+2

Step-by-step explanation:

I chose this equation because it had a - (negative) in front of x and has the y -intercept of +2

A negative x shows that the line has a negative slope which goes downward

A y-intercept of 2 shows that the line passes the y-axis at +2 which the graph shows.

Answer:

C. y=-x+2

Step-by-step explanation:

slope intercept formula: mx+b=y

m = slope

x= value of X

y= value of Y

b= y-intercept

y-intercept: the y-coordinate of the point at which the graph crosses the y-axis.

in this case the y-intercept is 2

slope formula: slope= y2-y1/x2-x1

the two ordered pairs: (2,0), and (0,2)

substitute the variables and solve

2-0/0-2= 2/-2= -1

slope: -1

now substitute the variable for the slope intercept form

y= -1x+2 or y= -x+2

) What is the distance between this pair of points?<br> (-5, 2) and (-5, 6)
Leni [432]

Answer:

d=4

Step-by-step explanation:

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>:

d=\sqrt{(-5-(-5))^2+(6-2)^2}

d=\sqrt{(-5+5)^2+(4)^2}

d=\sqrt{(0)^2+16}

d=\sqrt{0+16}

d=\sqrt{16}

d=4

What's the answer to this question
frutty [35]

Step-by-step explanation:

there are several things to be considered to solve this.

the strategy is to caucuses the volume of the full "box", and then to deduct the 3-dimensional triangle that is "cut off" from the oil.

then we know the volume of the pool.

next step is to calculate the volume of a "box" with the same layout but is only 20 cm deep.

then we know how much volume can be pumped out in 30 minutes.

and then we divide the whole volume by that small volume to see how many 30-minues units are needed to empty the whole pool.

and then we transform the 30- minutes units into actual minutes or hours.

so, let's begin :

the whole box's volume is

2×1×1.4 = 2.8 m³

the volume of the 3-D triangle we need to subtract is the area of the triangle × width of the pool (this pool width is the height of the 3-D triangle).

2×(1.4 - 0.6) × 1 / 2 = 2×0.8 × 1 / 2 = 1.6/2 = 0.8 m³

so, the volume of the pool is

2.8 - 0.8 = 2 m³

now, how much volume can the pump eliminate in 30 minutes ?

the content of a box

1×2×0.2 = 0.4 m³

as 20 cm = 0.2 m

so, the pump pumps out 0.4 m³ in 30 minutes.

and we need to empty 2 m³.

that means we need

2 / 0.4 = 5

30-minues units = 5×30 = 150 minutes = 2.5 hours.

Colin has to wait 2.5 hours (150 minutes) to empty the complete pool.

The sum of three numbers is 100. The second number is 2 times the third. The third number is 8 less than the first. What are the
8_murik_8 [283]

Answer:

Step-by-step explanation:x+y+z=100(let x ,y,z represent the first second and third numbers respectively)

Therefore,y=2z

z=x-8

y=2x-16

substituting the values of x,y and z into the question,we have

x+(2x-16)+(x-8)=100

Simplifying,we have

4x-24=100

adding 24 to both sides of the equation,

4x=100+24

4x=124

dividing both sides of the equation by the co-efficient of x,we have

4x/4=124/4

4.31=124

therefore,x=31.
