Answer 1
8x = -8
X= -1

Y=-8
Hope this help
Answer 2
8x + y = -8
 For this case what you should do is see the intersections with each of the axes and then join the ordered pairs.
 We have then:
 For the x axis: 
 y = 0
 Substituting in the equation:
 8x + (0) = - 8
 8x = -8
 x = -1
 For the y axis: 
 x = 0
 Substituting in the equation:
 8 (0) + y = -8
 0 + y = -8
 y = -8
 We graph the ordered pairs:
 (x1, y1) = (- 1, 0)
 (x2, y2) = (0, -8)

 See attached graph.

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(3, -2), B(6, -2), C(6, 5), and D(3, 5). What is the area of rectangle ABCD?

Answers

Answer:

21

Step-by-step explanation:

a = 6-3 = 3

b = 5 -(-2)= 7

Area = a*b = 3*7 = 21

The area of rectangle ABCD which is graphed in the coordinate plane with vertices A(3, -2), B(6, -2), C(6, 5), and D(3, 5) is 21 unit².

What is the area of a rectangle?

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, (a)is the length of the rectangle and (b) is the width of the rectangle.

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(3, -2), B(6, -2), C(6, 5), and D(3, 5).

The shortest distance(length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

The distance from A to B is the length of the rectangle. The distance of line segment AB is,

[tex]W= \sqrt{(3-6)^2 + (-2-(-2))^2}\\W = \sqrt{(-3)^2 + (0)^2}\\W=\sqrt{9}\\W=3\rm\; units[/tex]

The distance from B to C is the width of the rectangle. The distance of line segment BC is,

[tex]L = \sqrt{(6-6)^2 + (-2-5)^2}\\L = \sqrt{(0)^2 + (-7)^2}\\L=\sqrt{49}\\L=7\rm\; units[/tex]

Thus, the area of rectangle ABCD is,

[tex]A=7\times3\\A=21\rm\; unit^2[/tex]

Hence, the area of rectangle ABCD which is graphed in the coordinate plane with vertices A(3, -2), B(6, -2), C(6, 5), and D(3, 5) is 21 unit².

what is the answer to this question ?

Answers

If there is a really short way of doing this, I don't see it. The only way I know to do it is to find the third angle of both triangles. 

So for F the third angle for each of the pairs is
left side: 180 - (51 + 30) = 180 - 81 = 99
right side: 180 - (109 + 30) = 180 - 139 = 41
This is not the answer.

G
180 - (92 + 70) = 180 - 162 = 18
180 - (28 + 70) = 180 - 98 = 82
This is not the answer either.

H
180- (58 + 30) = 180 - (88) = 92
180 - (90  + 58) = 180 - 148 = 32
Not at all.

180 - (35 + 82) = 180 - 117 = 63
180 - (82 + 63) = 180 - 145 = 35
This pair has a third angle that is equal to the other triangle's pair. This is your answer.

Cougar Park is shaped like a parallelogram and has an area of 1/10 square mile. It’s base is 3/8 mile. What is its height?

Answers

To find the missing dimension (the height) you can use the formula A=bh and substitute and let you know. 1/10=3/8h. To find the missing factor (h) you will divide both sides by 3/8. 1/10 divided by 3/8 is the same as 1/10 x 8/3. The answer is 4/15 mile. You show this has h=4/15 mi.
4/15 Miles
The formula for the area of a parallelogram is A=b*h. We plug in the information that we know and solve for the missing height.
[tex] \frac{1}{10}= \frac{3}{8}*h [/tex]
Multiply both sides by the reciprocal of 3/8 which is 8/3 so it is canceled on the right side.
[tex]\frac{8}{3}*\frac{1}{10}= h [/tex]
multiply the factions to get 8/30. 8 and 30 have common factors of 2 and can reduce to 4/15

Solve the quadratic equation by completing the square.
x^2 - 10x + 18 = 0

Answers

Okay so basically, you subtract 18 on both sides since the 18 doesn't work, making the equation 
x² - 10x = -18
So then you add (b/2)², which is 25, to both sides, to get 
x² - 10x + 25 = 7
After this, you factor.
(x-5)(x-5) = 7
Then you simplify.
(x-5)² = 7
Then you solve for x.
√(x-5)² = √7
x-5 = (+ or -)√7

~ x= 5 (+ or -)√7 ~

F.Car A and Car B are at the same distance away from San Francisco after 4 hours.

Answers

The answers are A,D,F
Final answer:

Car A is traveling faster at the checkpoint because it must go past the speed of car B to reach the same distance.

Explanation:

Car A is traveling faster at the checkpoint because it must go past the speed of car B to reach the same distance.

To determine which car is traveling faster at the checkpoint, we need to compare their velocities. Car A has a positive, constant acceleration, which means its velocity is increasing. Car B, on the other hand, travels at a constant speed, which means its velocity remains the same.

Therefore, Car A is traveling faster at the checkpoint than Car B.

To answer this, first, you need to multiply the first bracket to the second bracket. Then, it will show like this: 4x(3x^2)-4x(2x)+4x(1)-2(3x^2)-2(-2x)-2(1)= 12x^3-8x^2+4x-6x^2+4x-2.
Then simplify them by adding or subtracting the same objects (same exponents and same variables). If they don't have the same objects, just let them be.
The final answer will be: -12x^3-14x^2+8x-2
The correct answer is 12x³-14x²+8x-2.

Explanation:
We use the distributive property:
4x*3x² - 4x*2x + 4x*1 - 2*3x² - 2*(-2x) - 2*1 = 12x² - 8x² + 4x - 6x² + 4x - 2.

Combining like terms, we have 12x³-14x²+8x-2.

In the figure, lines a, b, and c are parallel and m∠4=48° .

Drag and drop the correct angle measure for each angle.

Answers

m∠4=48° 
m<1 = m∠4=48° 
m<2 = 180 - 44 = 132
m<3 = m<2 = 132
m<5 = m∠4=48° 

The values of each angle are:

∠1 = 48

∠2 = 132

∠3 = 132

∠5 = 48

We have,

∠4 = 48

∠4 and ∠5 are corresponding angles.

so,

∠5 = 48

Now,

∠3 and ∠4 make a straight angle.

So,

∠3 + ∠4 = 180

∠3 = 180 - 48

∠3 = 132

Now,

∠2 and ∠3 are alternate angles.

So,

∠2 = ∠3 = 132

Now,

∠1 and ∠2 make a straight angle.

So,

∠1 + ∠2 = 180

∠1 = 180 - 132

∠1 = 48

Thus,

∠1 = 48

∠2 = 132

∠3 = 132

∠5 = 48

Y= -3x
Hope this help
Answer:
y = -3x - 3

Explanation:
The equation of line in slope-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept

1- getting the slope:
To get the slope, we will need two points from the curve. I will choose points (-1,0) and (-2,3)
slope = (y2-y1) / (x2-x1) = (3-0) / (-2--1) = -3
The equation now is:
y = -3x + c

2- getting the y-intercept:
The y-intercept is the value of y at x = 0. From the graph, we can directly get this value.
y-intercept = c = -3

Based on the above, the equation of the line is:
y = -3x - 3

What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 5.5? A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm. Perimeter = 50 cm, area = 155.25 cm2 Perimeter = 50 cm, area = 1,452 cm2 Perimeter = 154 cm, area = 155.25 cm2 Perimeter = 154 cm, area = 1,452 cm2

Answers

we know that
scale factor =5.5
the dimensions of the original rectangle are
length is  8 cm, and the width is  6 cm.
original perimeter=2*[8+6]-----> 28 cm
original area=8*6----> 48 cm²

perimeter of the larger rectangle=[scale factor]*original perimeter
perimeter of the larger rectangle=5.5*28-----> 154 cm

area of the larger rectangle=scale factor²*area original rectangle
area of the larger rectangle=5.5²*48-----> 1452 cm²

the answer is
perimeter=154 cm
area=1452 cm²
Answer:
perimeter is 154 cm
area is 1452 cm^2
This means that the last option is the correct one

Explanation:
1- getting the new dimensions:
We are given that the scale factor is 5.5
This means that:
new length = old length * scale factor
new width = old width * scale factor
We are given that:
scale factor = 5.5
old length = 8 cm
old width = 6 cm
Therefore:
new length = 8 * 5.5 = 44 cm
new width = 6 * 5.5 = 33 cm

2- getting the perimeter:
perimeter of the rectangle can be calculated as follows:
perimeter = 2(length + width)
We have:
length = 44 cm
width = 33 cm
This means that:
perimeter = 2(44+33)
perimeter = 2(77)
perimeter = 154 cm

3- getting the area:
area of rectangle can be calculated as follows:
area = length * width
We have:
length = 44 cm
width = 33 cm
This means that:
area = 44 * 33
area = 1452 cm^2
