Step-by-step explanation:

Given the 2 equations

x = 2.4545... → (1)

100x = 245.4545... → (2)

Subtract (1) from (2) eliminating the repeating decimal

99x = 243 ( divide both sides by 99 )

x = [tex]\frac{243}{99}[/tex]

Answer:

Dilations create similar figures because multiplying by the scale factor creates proportional sides while leaving the angle measure and the shape the same.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Perpendicular lines have the exact opposite slope of the other equation.

So the slope will be x or 1x. Plug in

-8 = 1(4) + b (b represents y-intercept) like y=mx+b

-8 = 4 + b (subtract 4 on both sides)

-12 = b

The equation is y = x - 12

C

solve

y + 8 = x - 4 (subtract 8 on both sides)

y = x - 12

Answer:

x = - 2, x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

2x² + x - 6 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 6 = - 12 and sum = + 1

The factors are + 4 and - 3

Use these factors to split the x- term

2x² + 4x - 3x - 6 = 0 ( factor the firs/second and third/fourth terms )

2x(x + 2) - 3(x + 2) = 0 ← factor out (x + 2) from each term

(x + 2)(2x - 3) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Answer:

The image of the point (1, -2) under a dilation of 3 is (3, -6).

Step-by-step explanation:

Correct statement is:

What are the coordinates of the image of the point (1, -2) under a dilation of 3 with the origin.

From Linear Algebra we get that dilation of a point with respect to another point is represented by:

[tex]\vec P' = \vec R + r\cdot (\vec P-\vec R)[/tex] (Eq. 1)

Where:

[tex]\vec R[/tex] - Reference point with respect to origin, dimensionless.

[tex]\vec P[/tex] - Original point with respect to origin, dimensionless.

[tex]r[/tex] - Dilation factor, dimensionless.

If we know that [tex]\vec R = (0,0)[/tex], [tex]\vec P = (1, -2)[/tex] and [tex]r = 3[/tex], then the coordinates of the image of the original point is:

[tex]\vec P' = (0,0) +3\cdot [(1,-2)-(0,0)][/tex]

[tex]\vec P' = (0,0) + 3\cdot (1,-2)[/tex]

[tex]\vec P' = (3,-6)[/tex]

The image of the point (1, -2) under a dilation of 3 is (3, -6).

Step-by-step explanation:

Answer:

The value of the gift card = v = $40

The visit to the skate cost = $8

The number of visits = n

∴ n = the value of the gift card over the cost of one visit to the skate

∴ n = v/8 = 40/8 = 5

Step-by-step explanation:

The general function for relating the value of the gift card, v, in terms if the number of visits, n. ⇒⇒⇒   v = 8n

Answer:

y+1= 1/4(x-4)

Answer:

Step-by-step explanation:

The perimeter is the sum of the measures of the 3 sides.

Sum the sides and equate to 75, that is

2x - 9 + 3x + 4 + 2x + 3 = 75, that is

7x - 2 = 75 ( add 2 to both sides )

7x = 77 ( divide both sides by 7 )

x = 11

Thus

AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m

BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m

AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m

Answer:

x=11

Side lengths:

AB=13

AC=25

BC=37

Step-by-step explanation:

We can create an equation based off of the given information. Then, we simplify the equation to solve.

[tex](2x+3)+(3x+4)+(2x-9)=75\\(2x+3x)+(3+4)+(2x-9)=75\\(5x+7)+(2x-9)=75\\(5x+2x)+(7-9)=75\\7x-2=75\\7x=77\\x=11[/tex]

Then, we insert 11 for x, and evaluate the expressions for the side lengths.

[tex]AB=2x-9=2*11-9=22-9=13[/tex]

[tex]AC=2x+3=2*11+3=22+3=25[/tex]

[tex]BC=3x+4=3*11+4=33+4=37[/tex]

Finally, we check.

13+25+37 is 75, so this should be correct.

Answer:

$7.5 = 3 pounds

Step-by-step explanation:

1. If $5 is equal to 2 pounds of cherries, you want to find what 1 pound of cherries cost. You should divided 5 by 2 and 2 by 2 to find what 1 pound of cherries cot.

2. That means that 1 pound of cherries cost $2.5.

3. Now we want to find how much money 3 pounds cost, so you should multiply the 2.5 and the 1 by 3.

4. Now that gets you to $7.5 for 3 pounds of cherries.s

Answer:

Converse: if 5=x then x+2=7

Inverse: if x+2 doesnt = 7 then x isnt 5

Contrapositive: if x doesnt equal five then x plus two doesnt equal seven

Step-by-step explanation:

We just did this last week :)

Answer:

z = 40° (V. O. A)

Now find x

40 + 25 + x = 180(A. S. P)

65 + x = 180

x = 180 - 65

x = 115°

Now find y

x = y (V. O. A)

Y = 115°

So angles are

X = 115°

Y = 115°

Z = 40°

Hope this helps, have a great day, have a wonderful weekend and stay safe!

Answer:

The primes up to 50 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47. The sequence of gaps—the differences between each prime and the next—is 1, 2, 2, 4, 2, 4, 2, 4, 6, 2, 6, 4, 2 and 4. The number 1 appears only once because all primes except for 2 are odd. The rest of the gaps are even numbers.

The conjecture which could be inferred from the sequence is that it is a list of prime numbers.

From the sequence given : 2, 3, 5, 7, 11, 13

All values in the sequence are prime numbers.

Prime numbers are numbers which have only two divisors which are 1 and the number itself.

Divisors of :

2 = 1 and 2

3 = 1 and 3

5 = 1 and 5

7 = 1 and 7

11 = 1 and 11

13 = 1 and 13

Hence, the conjecture which could be inferred from the sequence is that, the numbers are prime numbers.

Answer:

a) 30feet

b) 9.12feet

Step-by-step explanation:

a) Given the path of the ball is modeled by the equation y=-0.02(x-18)²+12​, where;

x is the​ ball's horizontal distance in feet from​ Amaya's position

y is the distance in feet from the ground to the ball.

The ball will be at the maximum height when dy/dx = 0

Differentiate the function:

dy/dx = 2(-0.02)(x-18)^(2-1)+0

dy/dx = -0.04(x-18)

Equate the resulting expression to zero and find x as shown;

-0.04(x-18) = 0

Open the parentheses

-0.04x+0.04(18) = 0

-0.04x+0.72 =0

-0.04x = -0.72

x = -0.72/-0.04

x = 18ft

Hence the ball is 18ft away from Amaya when it is at its maximum height

b) To get the balls height y when x = 30, we will substitute x = 30 into the equation given and calculate the value of y as shown:

y=-0.02(x-18)²+12

y = -0.02(30-18)²+12

y= -0.02(12)²+12

y = -0.02(144)+12

y = -2.88+12

y = 9.12 feet

Hence the Ball's height is 9.12feet when it crosses the net at x = 30.
