If x = 4, y =

Answer:

D) y=-1/2x+4

Step-by-step explanation:

D) y=-1/2x+4

In order to be parallel, it has to have the same slope (-1/2).  Also, if you plug in (-2,5) for x and y, it does pass through those coordinates.

Answer: Option A.

Step-by-step explanation:

The first step is to place the point of the compass in the vertex of the angle and draw an arc that connects both rays.

Then you put the compass in the points where the arc intersected the rays and draw two new arcs (with the radius of the compass constant)

The point where the two new arcs intersect will be the interior point.

Then the first step is: place the compass in the vertex of the angle.

The vertex is the common point to the two rays, in this case, we can see that the vertex is the point A.

Then you should place the compass in the point A, the correct option is option A.

Answer:

81, 243, 729, 2187, 6561

Step-by-step explanation:

Note that the

third term 9 = 3²

fourth term 27 = 3³

Thus to obtain a particular term in the sequence we require the exponent to be one less than the terms position n in the sequence, that is

[tex]a_{n}[/tex] = [tex]3^{n-1}[/tex] , thus

first term 1 → [tex]3^{1-1}[/tex] = [tex]3^{0}[/tex] = 1

The next 5 terms in the sequence are

[tex]a_{5}[/tex] = [tex]3^{5-1}[/tex] = [tex]3^{4}[/tex] = 81

[tex]a_{6}[/tex] = [tex]3^{6-1}[/tex] = [tex]3^{5}[/tex] = 243

[tex]a_{7}[/tex] = [tex]3^{7-1}[/tex] = [tex]3^{6}[/tex] = 729

[tex]a_{8}[/tex] = [tex]3^{8-1}[/tex] = [tex]3^{7}[/tex] = 2187

[tex]a_{9}[/tex] = [tex]3^{9-1}[/tex] = [tex]3^{8}[/tex] = 6561

Answer:

1: Angles in a triangle add up to 180°. The square represents a right angle (90°)

[tex]x=180-90-60=30[/tex]

2:

[tex]y=180-100-45=35[/tex]

3:

Angles on a straight line add up to 180°.

[tex]x=180-70=110[/tex]

4:

[tex]y=180-120=60[/tex]

The product 3/2 x 3/4 is greater than 3/8.

The correct answer is option (C) 3/2 x 3/4

"It is a number which is expressed as the ratio of two integers, where the denominator should not be equal to zero."

For given example,

We have been given a rational number 3/4 and the product of four rational numbers.

We need to find which product is greater than 3/4

3/4 = 0.75

Consider,

a) 1/2 x 3/4 = 3/8

⇒ 3/8 = 0.375

⇒ 0.375 < 0.75

b) 5/6 x 3/4 = 15/24

⇒ 15/24 = 0.625

⇒ 0.635 < 0.75

c) 3/2 x 3/4 = 9/8

⇒ 9/8 = 1.125

⇒ 1.125 > 0.75

⇒ (3/2 x 3/4 ) > 3/4

d) 2/5 x 3/4 = 3/10

⇒ 3/10 = 0.3

⇒ 0.3 < 0.75

Therefore, the product 3/2 x 3/4 is greater than 3/8.

The correct answer is option (C).

Answer:

$15

Step-by-step explanation:

1 chocolate cake and 6 egg tart costs $18.60.

1 chocolate cake and 24 egg tarts cost $29.40.

Find the difference in egg tarts first.

Difference in egg tarts = 24 - 6 = 18

Then, the difference in cost.

$29.40 - $18.60 = $10.80

Find the cost of 1 egg tart.

18 egg tarts = $10.80

18 egg tarts = $10.80

1 egg tart = $10.80 ÷ 18 = $0.60

To find the cost of a chocolate cake, you minus the cost of 6 tarts from $18.60.

6 egg tarts = $0.60 × 6 = $3.60

6 egg tarts = $0.60 × 6 = $3.601 chocolate cake = $18.60 - $3.60 = $15

Answer:

400 ounces

Step-by-step explanation:

x pound(s) = (16*x) ounces

25 pounds=(16*25) ounces

25 pounds= 400 ounces

400 ounces of quarters were stolen.

Given,

The robber stole only 25 pounds of quarters out of the coin machine. Quarters are weighed in ounces.

If there are 16 ounces in 1 pound.

We need to find out how many ounces of quarters were stolen.

16 ounces = 1 pound

Find how many pounds of quarters were stolen.

= 25 pounds of quarters.

Convert 25 pounds of quarters into ounces of quarters.

1 pound = 16 ounces

Multiplying 25 on both sides.

25 x 1 pound = 25 x 16 ounces.

25 pounds = 400 ounces.

This means 25 pounds of quarters is 400 ounces of quarters.

Thus 400 ounces of quarters were stolen.

Answer:

12x^2-5x-2

Step-by-step explanation:

Answer:

x = -3

Step-by-step explanation:

Step 1: Write out equation

6 - 4x = 6x - 8x + 12

Step 2: Combine like terms (x)

6 - 4x = -2x + 12

Step 3: Add 4x on both sides

6 = 2x + 12

Step 4: Subtract 12 on both sides

-6 = 2x

Step 5: Divide both sides by 2

-3 = x

Step 6: Rewrite

x = -3

Answer:

The answer is x= -3

Step-by-step explanation:

6 - 4x = 6x - 8x + 12

First, add like terms. (6x-8x)

6-4x=-2x+12

Then "add" 4x to both sides.

6=2x+12

Then subtract 12 from both sides.

-6=2x

The final step is to divide. Divide 2 from both.

Your answer is x= -3

If we have the graph of either a function or its derivative, we can find an approximate graph for the other function. This is because when a function is increasing, the derivative is positive, and when the function is decreasing, the derivative is negative.

Answer:

-17

Step-by-step explanation:

f(t)=-2t^2+ 1

f(-3)=-2*-3^2+1

f(-3)=-2*9+1

f(-3)=-18+1

f(-3)=-17

The value of the function f(t)=-2t²+ 1 for f(-3) will be - 17.We can find the value of f(-3) by putting -3 at the place of t

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range. In mathematics, functions serve as the fundamental building blocks for developing technology.

It is given that the function is,

f(t)=-2t²+ 1

We have to find the value of the function as t=-3.

We can find the value of f(-3) by putting -3 at the place of t and applying the arithmetic operation as,

f(t)=-2t²+ 1

f(-3)=-2(-3)²+1

f(-3)=-2(9)+1

f(-3)=-18+1

f(-3)= -17

Thus, the value of the function f(t)=-2t^2+ 1 for f(-3) will be -17. We can find the value of f(-3) by putting -3 in the place of t.

Answer:

-11+x is the variable form of the sum of -11 and a number

Answer:

2.50$

Step-by-step explanation:

you would divide 35 and 14

35/14=2.5

2.5=$2.50

Complementary angles are two angles that add up to 90 degrees

So, 2x + 3x = 90 we have to solve for x

5x = 90

Divide each side by 5

x = 18

Plug 18 into x for 3x and 2x

3x = 3(18) = 54

2x= 2(18) = 36

Answer:

Infinite Solutions

Step-by-step explanation:

To solve for this problem, we want to isolate x on one side of the equation.

Apply the distributive property on the right side:

[tex]3x - x - 5 = 2x+4 -9[/tex]

Combine like terms:

[tex]2x - 5 = 2x - 5[/tex]

Woah, we have the exact same thing on both sides of the equation. This means that we have infinite solutions, aka any value of x will satisfy this equation.

Test it out! Any value of x, whether its 1, 5, or 10000 will satisfy the equation.

So this has infinite solutions.
