Answer:c

Step-by-step explanation:

Answer:

(3x-16)(2x+15)=0

Answer:

21.42ft

Step-by-step explanation:

a²+b²=c² where "c" is the hypotenuse of a right triangle and "a" and "b" are the two other sides

now let's plug in the values

21²+b²=30²

b²= 30² - 21²

b²= 459

b= 21.42

Answer: A

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

For one scientific notation will not work with negative exponents therefore we can eliminate answer choices A and D

Secondly scientific notation usually has a decimal

Answer choice c does not have a decimal point leaving us with answer choice B

Answer: D x > -2

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

∠Y = 55°

Step-by-step explanation:

Since triangle ABC and XYZ are congruent, that means that...

∠A = ∠X

∠B = ∠Y

∠C = ∠Z

Since ∠Y = ∠B and ∠B = 55°, that means ∠Y = 55°.

Answer:

A- the graph of f(x) is shifted 7 units down

Step-by-step explanation:

Answer:Yes, they are similar.

If two triangles are congruent then all corresponding sides as well as corresponding angles of one triangle are equal to those of other triangles. This can happen in four cases

Step-by-step explanation:

Answer:

yes the are similar

Step-by-step explanation:

they are similar since they both have a 90⁰ angles and the lines are =. but I don't know if they count the size of the triangle if yes then they are not similar since they do not have the same area

Answer:

y = 5 ; x = 4

Step-by-step explanation:

Given :

5x + 6y = 50 - - - (1)

x - 6y = -26 - - - (2)

From (2)

x = - 26 + 6y

Put - 26 + 6y for x in (1)

5(-26 + 6y) + 6y = 50

-130 + 30y + 6y = 50

-130 + 36y = 50

-130 - 50 = - 36y

-180 = - 36y

y = 180 / 36

y = 5

Put y =5 in x = - 26 + 6y

x = - 26 + 6(5)

x = - 26 + 30

x = 4

y = 5 ; x = 4

Answer:

-20x+15

Step-by-step explanation:

You use foil method so you distribute it and it becomes -5*4x amd -5*-3 so it would be -20x+15

-5 x 4x=-20x and -5x x -3 = +15

-20x+15 is the answer

Answer:

2(x+1)(3x+1)

Step-by-step explanation:

(2x+2)(3x+1)

Apply the distributive property by multiplying each term of 2x+2 by each term of 3x+1.

6x^2+2x+6x+2

Combine 2x and 6x to get 8x.

6x^2+8x+2

Answer:

6x²+8x+2

Step-by-step explanation:

multiply each ferm in the first set of parenthess by each term in the second parentheses (FOIL)

2x times 3x +2x+ 2x times 3x+2

6x+2x+2 times 3x +2

6x²+2x+6x+2

now collect like terms

6x²+8x+2

Answer:

12 cubes

Step-by-step explanation:

If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...

24 / 2 = 12 cubes

Finally, we can see that each layer within the box will contain 12 cubes

Answer:

1.25 × 10^-4

Step-by-step explanation:

Move the decimal until it's at 1.25. You had to go right 4 times so it's negative. If it were 12500 then you'd do it until it was 1.2500 which would be going left so it'd be a positive 4

Given:

The equation is

[tex]y=\log_2x[/tex]

The domain is [tex]\{\dfrac{1}2, 1, 2, 4, 8, 16\}[/tex].

To find:

The graph of six points that would satisfy the equation.

Solution:

We have,

[tex]y=\log_2x[/tex]

For [tex]x=\dfrac{1}{2}[/tex],

[tex]y=\log_2\dfrac{1}{2}[/tex]

[tex]y=\log_22^{-1}[/tex]

[tex]y=-1[/tex]                          [tex][\because \log_aa^x=x][/tex]

Similarly, at x=1,

[tex]y=\log_22^0[/tex]

[tex]y=0[/tex]

At x=2,

[tex]y=\log_22^1[/tex]

[tex]y=1[/tex]                      [tex][\because \log_aa^x=x][/tex]

At x=4,

[tex]y=\log_22^2[/tex]

[tex]y=2[/tex]                      [tex][\because \log_aa^x=x][/tex]

At x=8,

[tex]y=\log_22^3[/tex]

[tex]y=3[/tex]                      [tex][\because \log_aa^x=x][/tex]

At x=16,

[tex]y=\log_22^4[/tex]

[tex]y=4[/tex]                      [tex][\because \log_aa^x=x][/tex]

Plot the points [tex](\dfrac{1}{2},-1),(1,0),(2,1),(4,2),(8,3),(16,4)[/tex] on a coordinate plane as shown below.

Answer:

d)

Step-by-step explanation:

turn 9x + y = 8 to slope intercept form

9x + y = 8

-9x         -9x

y = -9x + 8

m = -9

y intercept = 8

Answer:

= 4374.

Step-by-step explanation:

 it is important to understand the pattern hidden in such problem.Let’s give it a try 2, 6, 18, 54 and so on.It can be written as 2, 3*2, 9*2, 27*2 and so on.

This can be further written as2 (1, 3, 9, 27, and so on) as 2 is common in every term.Now if you see the chain 1,3,9, 27 and so….you will see a pattern hidden i.e. 3=1*3 ,9=1*3*3, 27=1*3*3*3 now 27 is the 4th term consist of three 3. So 8th term would consist of seven 3. 8th would be 8th term = 1*3*3*3*3*3*3*3 = 2187 Hence the 8th term for the series 2,6,18,54 would be= 2*2187 = 4374.
