Step-by-step explanation:

1^3 is 1

Answer:

The mistake is in part 2.

Step-by-step explanation:

2(1)^3 is 2(1) because 1*1*1 still =1. She was multiplying 1 by 3.

I tried but soory I can't understand

Answer:

D-60°

Step-by-step explanation:

K,L,M is collinear and JM=JL

M can only be extend to the left of K, otherwise it will overlap with L

JM = JL     ΔJML is isosceles triangle    ∠JML ≅ ∠JLM

∠JLM = 90 - ∠KJL = 90 - 30 = 60

∠JML = 60°

Step-by-step explanation:

The given inequality is :

[tex]-27\ge \dfrac{1}{2}(6x-12)[/tex]

Solving RHS of the inequality:

[tex]-27\ge \dfrac{1}{2}\times 2(3x-6)\\\\-27\ge (3x-6)[/tex]

Adding 6 both sides of the inequality

[tex]-27+6\ge (3x-6)+6\\\\-21\ge 3x\\\\x\le -7[/tex]

The attached figure shows the graph for the given inequality.

Step-by-step explanation:

10% more = 110% of the number.

110% of the number = 132

100% of the number = 132 * (10/11) = 120.

The number is 120.

Answer:

479.33

Step-by-step explanation:

10/30 is the same as 1/3 or 33.34%.

Multiply the fraction to the original price then subtract.

719 * 1/3 = 239.67

719 - 239.67 = 479.33

Best of Luck!

Answer:

There is no point where x = 3.5

Step-by-step explanation:

Given the inequality

5x – 3 > 14.5

We are to find the range of all values of x

Add 3 to both sides of the equation;

5x - 3 + 3 > 14.5+ 3

5x > 17.5

x > 17.5/5

x > 3.5

Also for the inequality;

[tex]\frac{2x+5}{3} <4\\[/tex]

Cross multiply;

[tex]2x+5 < 3(4)\\2x + 5 < 12\\[/tex]

Subtract from both sides;

[tex]2x + 5-5 < 12-5\\2x < 7\\x<7/2\\x<3.5[/tex]

The solution to both inequalities are x > 3.5 and x < 3.5. Since there is no point where x = 3.5, hence the solution will have solution on all real numbers except at x = 3.5

Answer:

When solving the first inequality, you get x > 3.5. When solving the second inequality, you get x < 3.5. The solution of an "or” compound in equality is everything in both solution sets, so the solution set is all of the numbers less than 3.5 and greater than 3.5. Since neither of the inequalities includes 3.5, the compound inequality has a solution of all real numbers except 3.5.

Given:

[tex]h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}[/tex]

To find:

The recursive formula.

Solution:

We have,

[tex]h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}[/tex]

It is in the form of explicate formula of a GP, .i.e., [tex]a_n=ar^{n-1}[/tex].

Here, [tex]a=-91[/tex] and [tex]r=-\dfrac{1}{7}[/tex].

The recursive formula of a GP is

[tex]a_n=a_{n-1}\times r[/tex]

Using this the recursive formula for given problem is

[tex]h(n)=h(n-1)\times (-\dfrac{1}{7})[/tex]

Therefore, the required recursive formula is [tex]h(n)=h(n-1)\times (-\dfrac{1}{7})[/tex].

Answer:

A)The function is negative when x is less than 0

Step-by-step explanation:

Answer:

p = 1 ; q = 10,000

Step-by-step explanation:

Number of distinct colored balls = 10

Number of balls picked with replacement = 4

Probability = (number of required outcome / number of total possible outcomes)

Distinct picks :

P(1st) = 1 /10

P(2nd) = 1/10

P(3rd) = 1/10

P(4th) = 1/10

Expected Numbe of distinct color:

P(1st) * P(2nd) * P(3rd) * P(4th)

1/10 * 1/10 * 1/10 * 1/10

= 1/10000

p/q = 1/ 10000

p = 1 ; q = 10,000

Answer:

mid point of AB (0.5 , 0)

Step-by-step explanation:

2x + 5y = 1      2x = 1 - 5y

y = 2xy+ 5 = (1 - 5y)*y + 5 = y - 5y² + 5

y-y = y - 5y² + 5 - y = - 5y² + 5

0 = - 5y² + 5

5y² = 5

y² = 1

y = 1 or y = -1

if y = 1       x = 1/2 (1 - 5) = -2   .... point A (-2 , 1)

if y = -1      x = 1/2 (1 + 5) = 3   ..... point B (3 , -1)

mid point of AB (x' , y') :  x' = 1/2 (x₁ + x₂) = 1/2 (-2 + 3) = 1/2

                                        y' =  1/2 (y₁ + y₂) = 1/2 (-1 + 1) = 0    

Answer:

The inverse of f is

[tex]g(x) = 2x[/tex]

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=\frac{1}{2}x[/tex]

A function g is the inverse of function f if for y = f(x), x = g(y)

[tex]y=\frac{1}{2}x[/tex]

Replace x with y

[tex]x=\frac{1}{2}y[/tex]

Solve for y

[tex]y = 2x[/tex]

Therefore, the inverse of f is

[tex]g(x) = 2x[/tex]

Answer:

Step-by-step explanation:

Let the area of the two triangles be expressed as;

f(x)= 4x^2+6x

g(x)=3x^2-x

Taking the difference

h(x) = f(x) - g(x)

h(x) = 4x ^2+6x - 3x^2-x

Collect like terms'

h(x) = 4x ^2 - 3x^2+6x-x

h(x) = x ^2 + 5x

Hence the difference is  x^2 + 5x

Note that the functions were assumed. The same methos can be applied to any other given functions.

Answer:

B: h(x) = 4x2 – 4x + 11
