Can I get some help with this is the Last question

We are given:                                                                                                        

AB = 7x + 10

BD = 9x - 2

∠DBC = 9y - 9

∠ABC = 90°

AB = BD

Solving for x:                                                                                                          

We are given that AB = BD

7x + 10 = 9x - 2               [since AB = 7x+10 and BD = 9x-2]

10 = 2x - 2                       [subtracting 7x from both sides]

2x = 12                            [adding 2 on both sides]

x = 6                               [dividing both sides by 2]

Hence, x = 6

Solving for y:_______________________________________________  

We know that AD is a straight line,

So, ∠ABC and ∠DBC must form a linear pair

∠ABC + ∠DBC = 180°

90 + 9y-9 = 180

9y - 9 = 90             [subtracting 90 from both sides]

9y = 99                  [adding 9 on both sides]

y = 11                      [dividing both sides by 9]

Hence, y = 11

Step-by-step explanation:

Answer: The first one

Step-by-step explanation:

3a + 11 > 5

Subtract 11 from both sides:-

3a > 5 - 11

3a > -6

a > -2

Answer:

It would be the first one

Step-by-step explanation:

problem---> 3a + 11 > 5

FIND a

1. Subtract 11 from both sides:-

which would look like this "3a > 5 - 11"

=3a > -6

a > -2

ANSWER; C.

Answer:

7x < 60

Step-by-step explanation:

Answer:

y=5x = 1/5 is bottom middle

y= -1/5x + 5 is top middle

y= -5x - 1/5 bottom left

y= 1/5x - 5 top left

Step-by-step explanation:

29 cookies

Carla has X cookies

Andrew has 8+ 2X cookies

x + 8 + 2x = 29

3x = 29-8

3x= 21

x = 7 / Carla has 7 cookies

8+ 2x = 8+2•7= 8+14=22 / Andrew has 22 cookies

Five Degree

End Behavior

When x approaches negative infinity, f(x) approaches the negative infinity as well.

When x approaches positive infinity, f(x) approaches positive infinity.

Step-by-step explanation:

[tex]y = 4 {x}^{3} + 3 {x}^{5} - {x}^{2} - 2[/tex]

A five-degree polynomial function. Rearrange the terms.

[tex]y = 3 {x}^{5} + 4 {x}^{3} - {x}^{2} - 2[/tex]

Because it is an odd-degree function, the graph increases from negative infinity and ends by increasing at positive infinity.

When x approaches negative infinity, f(x) approaches the negative infinity as well.

When x approaches positive infinity, f(x) approaches positive infinity.

Answer:

One solution

Step-by-step explanation:

maybe

Answer:

There is only one solution to the equation.

x = 0

Step-by-step explanation:

Let rewrite the following equation so that x will be separated from the other numbers. So we do the following......

[tex]\frac{x+4}{4} = \frac{x +3}{3}[/tex]

[tex]12(\frac{x+4}{4}) = 12(\frac{x +3}{3})[/tex]

[tex]3(x +4) = 4(x+3)[/tex]

[tex]3x +12 = 4x +12[/tex]

[tex]12 = 4x - 3x +12[/tex]

[tex]0 = x[/tex]

Answer: The first option and the third option

Step-by-step explanation: You are not supposed to find something equivalent to the fraction, you have to divide the fraction.

13824 ÷ 8 = 1728

Then it is when you try to find a number equivalent to 1728. 12 to the power of 3 equals 1728

12×12=144

144×12=1728

12 to the power of 3 is equivalent to 1728

These are wrong: 2 to the power of three is unequivalent and so is 12 to the power of 6 and 6 to the power of 3

2 to the power of 6 is 64

2×2=4

4×2=8

8×2=16

16×2=32

32×2=64

3 to the power of 3 is 27

3×3=9

9×3=27

64 times 27 equals 1728 so it's equivalent and that means that our answers are A, the 1st option , and C, the 3rd option

The equivalent expression will be;

⇒ 12³

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 6³ × 2⁶ / 2³

Now,

Since, The expression is,

⇒ 6³ × 2⁶ / 2³

Solve as;

⇒ 6³ × 2⁶ × 2⁻³

⇒ 6³ × 2⁶⁻³

⇒ 6³ × 2³

⇒ (6 × 2)³

⇒ 12³

Thus, We get;

⇒ 6³ × 2⁶ / 2³ = 12³

Answer:

8f - 8d + 2e

Step-by-step explanation:

8f-12d+4d+2e = 8f - 8d + 2e

Answer:

−8d+8f+5.436564

Step-by-step explanation:

Let's simplify step-by-step.

4(2f−3d)+2(2d+2.718282)

Distribute:

=(4)(2f)+(4)(−3d)+(2)(2d)+(2)(2.718282)

=8f+−12d+4d+5.436564

Combine Like Terms:

=8f+−12d+4d+5.436564

=(−12d+4d)+(8f)+(5.436564)

=−8d+8f+5.436564

Answer:

=−8d+8f+5.436564

Step-by-step explanation:

We can use standard form to make it simpler to deal with.

0.45=45×10^-2

0.3=3×10^-1

Now 45÷3=15

10^-2÷10^-1=10^-1

So the answer is 15×10^-1 OR 1.5

Answer:

n=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6(2n+5)=66

(6)(2n)+(6)(5)=66(Distribute)

12n+30=66

Step 2: Subtract 30 from both sides.

12n+30−30=66−30

12n=36

Step 3: Divide both sides by 12.

12n/12    = 36/12

n=3

Answer:

n = 3

Step-by-step explanation:

Distribute 6 into 2n+5, which is 12n +30

Subtract 30 from 66, which is 36

Divide 36 by 12

You're left with n = 3

Or in numbers:

6(2n+5)=66

12n+30=66

12n=36

n=3

Answer:

11.76 ft or 12 ft

Step-by-step explanation:

tan 30= x/12            tan 22=  x/12

x= 6.92                    x= 4.84

6.92+4.84=11.76ft

11.76 rounded to the nearest foot= 12ft

Answer:

Sale price of the watch = $60

Step-by-step explanation:

Given that:

Cost of the watch at Macy's = $150

Discount on watch = 60%

Amount of discount = 60% of cost

Amount of discount = [tex]\frac{60}{100}*150[/tex]

Amount of discount = 0.60*150 = $90

Price after discount = 150-90

Price after discount  = $60

Hence,

Sale price of the watch = $60

Answer:

2.33

Step-by-step explanation:

Answer:

Answer:6:45

Step-by-step explanation:

Answer:

x = 30

Step-by-step explanation:

a ratio is just a fraction

9:45 = 9/45

6:x = 6/x

now you have 9/45 = 6/x

cross multiply:

9 * x = 45 * 6

9x = 270

divide both sides by 9

9x/9 = 270/9

x = 30
