Use slopes to determine if the lines -7x-2y=-8 and 2x+7y=-3 are perpendicular or not

Answers

Answer 1

Answer:

Since slopes of both lines are not negative reciprocals. Therefore Lines are not perpendicular to each other

Step-by-step explanation:

Slope of -7x-2y=-8 is -7/2

Slope of 2x+7y=-3 is -2/7

For perpendicular lines slopes are negative reciprocals of each other

A. y2-4x+ 2
B. yz 4x + 2
C. ys - 4x + 2
D. y = 4x+2​

Answers

Answer:

D) y = 4x + 2

Step-by-step explanation:

Explanation:-

Given ( 0, 2) ( -1 , -2 )

Given in equalities     y = 4x + 2

    put point  (0,2)  in equation y = 4x +2

                                                 2 = 4(0) +2

                                                2 = 2

Therefore satisfies the point (0,2) equation   y = 4x +2

 put point  (-1,-2)  in equation y = 4x +2

                                               -2 = 4(-1)+2

                                              -2  = -2

Therefore satisfies the point (-1,-2) equation   y = 4x +2

with a circle drawn on the map. The center of the lake is 19 miles east and 3 miles south of the town hall, and the
radius of the lake is 0.5 miles.
If the positive x-axis represents east and the positive y-axis represents north, which equation represents the lake?
O (x + 19)2 + (y - 3)2 = 0.5
O (x – 19)2 + (y + 3)2 = 0.5
O (x + 19)2 + y - 3)2 = 0.25

Answers

The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25

What is an equation?

An equation is an expression that shows the relationship between two or more variables and numbers.

The equation for a circle is given as:

(x - h)² + (y - k)² = r²

Where (h, k) is the center of the circle and r is the radius.

The center of the lake is 19 miles east and 3 miles south, i.e. (-19, -3) and the radius is 0.5 miles.

The equation of the lake is:

(x - (-19))² + (y - (-3))² = 0.5²

(x + 19)² + (y + 3)² = 0.25

The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25

Answer: D.  [tex](x-19)^2+(y+3)^2=0.25[/tex]

Step-by-step explanation:

Let's review what we know:

the lake is circularthe town hall is at the originthe center of the lake is 19 miles east of the origin and3 miles south of itthe radius of the lake is 0.5 miles

A circle can be depicted on the coordinate plane with the equation [tex](x-h)^2+(y-k)=r^2[/tex], where:

(h, k) is the center of the circleand r is the radius of the circle

19 miles east of the origin would be 19 units to the right of the origin on the coordinate plane, as east is the rightwards direction in real life. In short, h = 19.

Let's plug in that value: [tex](x-(19))^2+(y-k)^2=r^2[/tex].

So we know that the x-coordinate defining part of the equation would have to be [tex](x-19)^2[/tex].

Meanwhile, 3 miles south of the origin would be modeled as three units underneath it, because south would be considered "downwards". The y-value (k) would be negative 3.

Putting what we have so far together, the center of the circle would be (19, -3).

Therefore, the y-coordinate defining part of the equation would be [tex](y+3)^2[/tex].

Here's what the equation looks like with the work we've completed so far: [tex](x-19)^2+(y+3)^2=r^2[/tex]

Finally, let's plug in the radius value 0.5.

0.5 * 0.5 = 0.25

Ailani would use the equation [tex](x-19)^2+(y+3)^2=0.25[/tex] to model the lake in relation to the town hall. I hope that makes sense!

Solve the following equations
7(3x + 5) - x = 75

Answers

Answer:

x = 2

Step-by-step explanation:

7(3x + 5) - x = 75

1. Distributive property

multiply 7 by whatever is in the parenthesis

7*3x + 7*5 - x = 75

21x + 35 - x = 75

2. Combine like terms

21x - x = 20x

20x + 35 = 75

3. Subtract 35 on both sides

20x + 35 - 35 = 75 - 35

20x = 40

4. Divide both sides by 20 since u want to isolate the variable

20x/20 = 40/20

x = 2

And thats ur answer

Step-by-step explanation:

The height of triangle = 5 yd

We need to find area of triangle.

The formula used is: [tex]Area\: of\: triangle=\frac{1}{2}\times base \times height[/tex]

Putting values and finding area

[tex]Area\: of\: triangle=\frac{1}{2}\times base \times height\\Area\: of\: triangle=\frac{1}{2}\times 8 \times 5\\Area\: of\: triangle=4 \times 5\\Area\: of\: triangle=20\:square\:yards[/tex]
