What do the following two equations represent?
-4x - 5y = -4

4x + 5y = 4
(parallel, perpendicular, equal, or none of the above)

y = 2x + 7 in the equation 8x - 4y = -28, isolate y on one side by subtracting 8x from both sides and then dividing by -4.

Solve for y: 8x - 4y = -28

Start by isolating y on one side of the equation.

Subtract 8x from both sides to get -4y = -8x - 28.

Finally, divide by -4 to find y = 2x + 7.

Answer:

C y=1/2cos(x)-2

Final answer:

The simplest form of the expression √324 * a^2 * b^6 is 18ab^3, which corresponds to Option A.

Explanation:

First, let's simplify the expression √324 * a^2 * b^6. The square root of 324 is 18, since 18 x 18 = 324. Now, we simplify 18 * a^2 * b^6 which gives us 18ab^3 when taking the square root of each term (a squared is a times a, and the b to the power of 6 simplifies to b to the power of 3 because √(b^6) = b^3).

The expression is already in its simplest form as an integer power. Therefore, the correct answer is Option A. 18ab^3.

Answer:

x>2

Step-by-step explanation:

The solution of inequality is,

⇒ x > 2

We have to given that;

The inequality is,

⇒ 8x + 4 > 20

Now, We can solve the inequality as;

⇒ 8x + 4 > 20

⇒ 8x + 4 - 4 > 20 - 4

⇒ 8x > 16

⇒ 8x - 16 > 0

⇒ 8 (x - 2) > 0

⇒ x - 2 > 0

⇒ x > 2

Since, 8 ≠ 0

Hence, The solution of inequality is,

⇒ x > 2

Answer:

If you are looking for coordinates then its (0,5) (5,-20)

Step-by-step explanation:

Mr. Mole's burrow lies 5 meters below the ground. This is the same as saying that when Time is 0, Elevation is -5.

Therefore, the graph of the relationship should pass through the point (0,-5)

We are also given the rate of change of the relationship: 3 meters per minute. This means that when Time increases by 1, Elevation decreases by 3.

Therefore, the graph should also pass through the point                                (0+1,-5-3), which is the point (1,-8) However, this point doesn't appear on the grid! We need to find an equivalent pair of corresponding changes that would help us find a point that we can graph.

Note, for instance, that when Time increases by 5, Elevation decreases by 5x3= 15. Therefore, the graph should pass through the point

(0+5,-5-15)which is the point (5,-20)

Area of a parallelogram = base × height

Step-by-step explanation:

A parallelogram is a quadrilateral with opposite sides parallel and equal to each other. Opposite angles are equal . The picture below is a parallelogram. Notice that angle D is equals to angle B and angle A is equals to angle C.

The height is gotten by drawing a straight line from a point to form a right angle triangle.  If the height is unknown you can use Pythagoras theorem to get the height when the base of the right angle triangle and sides of the parallelogram is known.

If the base of the parallelogram is 10 . 25 cm (side AB and DC ) and the height is 4.28 cm , the

area =  base × height

area = 10.25 × 4.28 = 43.87  cm²

The value is already in it nearest hundredth.

We're going from 1u : 3m to 1u : 9m so the new images will be three times smaller in each linear dimension.  So instead of a 3x9 box we get a 1x3 box.

Answer:

about 317

Step-by-step explanation:

You can break up the pentagon into 5 isoceles triangles

with length of 20√3/3 for the legs. Using the law of Sines are formula, we can see the area of one triangle is the leg * leg * sin(joining angle) /2.

The angle measure between it is 360/5 = 72 degrees.

So we plug it in and we get 317.01 ish.

I hope that helped and i need a brainly mark please :)

The Area of Pentagon is 363.43 mm².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

We have, Apothem= 10mm

So, Perimeter of Pentagon

= 10 x 7.267

= 72.67 mm

Now, side of pentagon = 72.67/ 5= 14.534 mm

So, Area of Pentagon

= 1/4 √5(5+2√5) a²

= 1/4 √5(5+2√5) (14.534)²

= 363.43 mm²

Tomo can make 4 batches of brownies.

Step-by-step explanation:

The way I did it is I subtract and counted how many times I subtracted until I got to zero. Like so: 4/3 - 1/3 = 3/3.  3/3 - 1/3 = 2/3. 2/3 - 1/3 = 1/3. 1/3 - 1/3 = 0.

Count it, and it equals four.

Answer:

The ordered pair is (1,8)

Step-by-step explanation:

Final answer:

The corresponding ordered pair for the function value f(1) = 8 is (1, 8), with 1 being the input and 8 being the output of the function.

Explanation:

If f(1) = 8, then the corresponding ordered pair is (1, 8). In function notation, the first value in the ordered pair is the input to the function (also known as the x-value or independent variable), and the second value is the output (also known as the y-value or dependent variable). Therefore, having f(1) = 8 tells us that when the input is 1, the output is 8, forming the ordered pair (1, 8).

Answer:

The third side is 8

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse

a^2 + 15^2 = 17^2

a^2 +225 = 289

Subtract 225 from each side

a^2 +225-225=289-225

a^2 = 64

Take the square root of each side

sqrt(a^2) = sqrt(64)

a= 8
