5/7

Answer:

B

Step-by-step explanation:

B because the graph doesn't show a liner line

but im not really sure nout it tho

Answer:

slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Answer:

Take the coordinates of each vertex (corner point) and subtract 2 from the x-coordinate; leave the y-coordinate alone.

Step-by-step explanation:

Example: If one vertex is the point (5, 3), then it moves left 2 units to (3, 3).

If a vertex is at (-3, 1), then it moves 2 units left to (-5, 1).

Answer:

37) ±√29 - 4

Completing the square utilizes this formula [tex](\frac{b}{2})^{2}[/tex]. We know that b=8, 8 can be plugged into this formula to get [tex](\frac{8}{2})^2[/tex]. Simplify to get 16. Now, we can add this into the equation to get [tex]k^{2}+8k+13=26[/tex]. Subtract 26 to both sides, so the equation can equal to 0. [tex]k^{2} +8k-13=0[/tex] would be the resulting equation. Now, let's use quadratic formula to find the solution. The quadratic formula is (-b+-√b^2-4ac) / 2a. Plug in all of our values to get (-8+-√8^2-4(1)(-13)/2(1). Simplify the equation to get ±√29 - 4.

38) ±√21 - 2

Let's use the same formula. b=4, so [tex](\frac{4}{2} )^2[/tex]. Simplify to get 4. Add that into the equation to get [tex]x^{2}+4x-5=12[/tex]. Subtract 8 on both sides, so the equation can equal to 0. [tex]x^{2}+4x-17=0[/tex] would be the result. Use the quadratic formula again to find the solution. Plug in all of the values to get ±√21 - 2

Answer:

17(x-2)

Step-by-step explanation:

Given the expression

17x - 34

We are to factorize it

Get their factors

17x = 17 * x

34 = 17 * 2

Since 17 is common to both factors, hence 17 is the GCF

17x - 34 = 17(x - 2)

Hence the equivalent expression is 17(x-2)

Answer:

No

Step-by-step explanation:

Answer:

1) Use translation to coincide the center of a circle with the center of the other circle.

2) We construct the respective loci for the circles.

3) Compare each loci by direct inspection ([tex]f(x,y)[/tex] must be the same and radii must be different but constant) to conclude the similarity of the two circles.

Step-by-step explanation:

Geometrically speaking, a circle is formed after knowing its center and radius.

1) Use translation to coincide the center of a circle with the center of the other circle. In this case, we translate the center ([tex]C_{A} (x,y) = (6,7)[/tex]) of the circle A to the location of the center of the circle B ([tex]C_{B}(x,y) = (2,4)[/tex]):

[tex]C_{A'} (x,y) = (6,7) + [(2,4) - (6,7)][/tex]

[tex]C_{A'} (x,y) = (2,4)[/tex]

2) We construct the respective loci for the circles.

By Analytical Geometric, a circle is represented by the following locus:

[tex](x-h)^{2}+(y-k)^{2} = r^{2}[/tex]

Where:

[tex]x, y[/tex] - Coordinates of a point of the circunference.

[tex]h, k[/tex] - Coordinates of the center of the circle.

[tex]r[/tex] - Radius of the circle.

3) Compare each loci by direct inspection ([tex]f(x,y)[/tex] must be the same and radii must be different but constant) to conclude the similarity of the two circles.

Then, the circles A' and B are represented by the following loci:

Circle A'

[tex](x-2)^{2} + (y-4)^{2} = 16[/tex]

Circle B

[tex](x-2)^{2} + (y-4)^{2} = 256[/tex]

Since both the [tex]f(x,y)[/tex] component of each circle is the same and radii are different but constant, then we conclude that circle A is similar to circle B.

Answer:

72 is equal to 2 yards.

Explanation:

There are 36 inches in one yard.

(another way to look at this is there are 3 feet in one yard, each feet is 12 inches. So, 12 multiplied by 3 is equal to 36 inches, or one yard)

Then, since in this question we are finding out in relation to 2 yards, add 36 inches + 36 inches, and that is equal to 72 inches.

72 and 72 are equal :)

Answer:

4

Step-by-step explanation:

-18, -15, -10, -5, 4, 5, 5, 11, 14

There are 9 terms. So the one in the middle is the median.

-18, -15, -10, -5, 4, 5, 5, 11, 14

 1      2    3   4   5  6  7  8  9

So 4 is the median.

Answer:

F(x) represents the zeros of the given quadratic function. i.e. the linear factors represents zero when we resolve the expression

Step-by-step explanation:

Describing the relationship between the zeros of the quadratic function and the linear factors of the expression using an example as shown below

lets describe this using the example below :

quadratic expression  : F(x) = ax^2 + bx + c

let the linear factors of  F( x ) = 0

F(x) represents the zeros of the given quadratic function above i.e. the linear factors represents zero when we resolve the expression

Answer:

152

Step-by-step explanation:

this is because there is 360 degrees in a circle and if you subtract 98 and 110 from 360 you get 152.

Answer

the diameter is 44

Step-by-step explanation:

the radius is just half of the diameter so to get the diameter from the radius just multiply it by two.

Answer:

7.1

Step-by-step explanation:

Once again we can use trig ratios to solve for ST

First we must recall the trig function

Sin = Opposite over Hypotenuse

Cos = Adjacent over Hypotenuse

Tan = Opposite over Adjacent

We are given the measure of an angle and the length of the hypotenuse

Of the given angle we need to find the adjacent side length

When working with the hypotenuse and adjacent we use trig function cosine

That being said we want to create an equation ( remember cos = adjacent over hypotenuse ) ( let ST = x)

[tex]cos(42)=\frac{x}{9.5}[/tex]

now we solve for x

Step 1 multiply each side by 9.5

[tex]cos(42)*9.5=9.5cos(42)=7.059875842\\\frac{x}{9.5} *9.5=x[/tex]

we're left with x = 7.059875842

Finally we round to the nearest tenth and get that the answer is 7.1

Answer:

x=9

Answer:

D. (-5, -4)

Step-by-step explanation:

When making a rotation 90° clockwise, the coordinates will swap places. However, the x value will be the opposite and the y value will stay the same.

90° clockwise rule:

(x, y) ---> (y, -x)

(4, -5) ---> (-5, -4)

Answer:

r = 4units

Step-by-step explanation:

The standard foem of equation of a line is expressed as;

(x-a)² + (y-b)² = r²

r is the radius

Compare with the given equation (x - 2)^2 + (y + 1)^2 = 16

r² = 16

r = √16

r = 4

Hence the radius of the circle is 4

Answer:

4th

Step-by-step explanation:

string length is 0.5m and the wavelengths are 0.25meters. This tells us there are two complete waves in the guitar string. This gives us a total of four antinodes; thus we are in the fourth harmonic.

Answer:

5x

Step-by-step explanation:

If the blank were to be occupied with 5x there would be no solutions

Observe...

5x - 8 = 5x + 2

* subtract 5x from each side *

5x - 5x cancels out

5x - 5x cancels out

we're left with -8 = 2

which is not true

Hence if the blank = 5x the equation will have no solution

Answer:

7 pizzas

Step-by-step explanation:

18 people × 3 slices each = 54 slices

54 ÷ 8 = 6.75

7 pizzas

Answer:

They should order 7 pizzas.

Step-by-step explanation:

18 people x 3 slices per person = 54 slices you will need for everyone

54 slices divided by 8 = 6.75 pizzas.

Round 6.75 to 7 pizzas.

They should order 7 pizzas because you cannot ask the pizza place for 6.75 pizzas.
