2 answers:

Alika [10]4 years ago

The answer to this question would be: B. JK and LM meet at a right angle.

The reversed T symbol in this question means "perpendicular". That means the JK and LM line have 90-degree angle difference. A straight angle is 180 degree and right angle mean 90 degrees.
A perpendicular line should be in the same plane and intersect each other.

Convert this equation to slope-intercept form:<br><br> 25x + 10y = 1,000

densk [106]

Answer:

y = -2.5x +100

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

We need to solve for y

25x+ 10y =1000

Subtract 25x from each side

25x-25x+10y = -25x +1000

10y = -25x+1000

Divide each side by 10

10y/10 = -25x/10 +1000/10

y = -2.5x +100

Write the following coordinates where they belong in the line segments below. (5 1/2, -4 1/4) _______ (3 3/4, -1 1/4)

Ket [755]

ANSWER

$(4 \frac{5}{8} , - 2\frac{3}{4} )$

EXPLANATION

The end points of the segment are:

$(5 \frac{1}{2} ,-4 \frac{1}{4} )$

and

$(3 \frac{3}{4} ,-1 \frac{1}{4} )$

The box represents the midpoint of the two points.

Using the midpoint formula;

$( \frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )$

We substitute the end points of the line segment to obtain,

$( \frac{5 \frac{1}{2} +3 \frac{3}{4} }{2} , \frac{ - 4 \frac{1}{?} + - 1 \frac{1}{4} }{2} )$

This simplifies to:

$( \frac{37}{8} , - \frac{11}{4} )$

We convert back to mixed numbers to get,

$(4 \frac{5}{8} , - 2\frac{3}{4} )$

The correct choice is B

On a map, a distance of 2 cm represents 15 km. What is the distance (in km) between two cities that are 11 cm apart on the map?

GenaCL600 [577]

Answer:

82.5 km

Step-by-step explanation:

Given:

$\frac{2cm}{15km} =\frac{11cm}{?km}$

Cross-multiply.

2x = 11(15)

Divide both sides by 2 and solve for x.

x = 82.5 km
