state whether the lines represented by the equations y=1/2x-1 and y+4=-1/2(x-2) are parallel, perpendicular, or neither.

1 answer:

7 0

Parallel because they have the same slope. Y+4= -1/2(x-2) is in point slope form, simplified to y intercept form is y=1/2-5... The slope (m) in both equations is the same, if you graphed the equations they would be parallel

Add –12 + 20, then divide the sum by –4

Illusion [34]

-12 + 20 = 8

then divide the answer by -4

8/(-4) = -2

when you divide a negative number, the answer will be the opposite sign of the numerator

-2 is your answer

hope this helps

What is the slope of the line that passes through the poiņts (-10, 4) and (-10,8)?

anygoal [31]

Answer:

Slope is undefined

Step-by-step explanation:

Slope is calculated by $\frac{y1-y2}{x1-x2}$ so now you put the points (-10,4) and (-10,8) into that.

Since both x values are the same you can tell that the line is a vertial line meaning the slope is undefined.

The lead statue of the Korean War Memorial in Washington DC casts a 43.5 inch shadow at the same time a nearby tourist casts a 3

AfilCa [17]

Answer:

The lead statue is 87 inches tall

Step-by-step explanation:

Let

x ----> the height of the lead statue

using proportion

we know that

The height of the lead statue divided by the length of his shadow must be equal to the height of the tourist divided by the length of his shadow.

$\frac{x}{43.5}=\frac{64}{32}\\\\\frac{x}{43.5}=2\\\\x=2(43.5)\\\\x=87\ in$
