Answer:

4/3

Step-by-step explanation:

Answer: 1. 3/8-1/4=1/8

2. 3/8+1/4=5/8

3. x=5/8

Step-by-step explanation: 1. you have to subtract 3/8 by 1/4 because you have to use the largest number to subtract for the smallest number so 3/8-1/4=1/8

2. Add by adding 3/8 by 1/4 because you have to find the value of x so 3/8+1/4=5/8

3. look at number 2. and the answer is x= 5/8

Answer:

Step-by-step explanation:

Answer:

Horizontal Asymptote → y = 17

Step-by-step explanation:

Given function is f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]

Here, the parent function is g(x) = [tex]\frac{2}{5}(16)^x[/tex]

Parent function has a horizontal asymptote as y = 0

If the function g(x) is shifted 13 units left and 17 units up, new function will be f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]

When the parent function is shifted 17 units up, horizontal asymptote shifts 17 units upwards.

Therefore, horizontal asymptote of the image function becomes y = 17.

Answer:

All terms of the equation were divided by 4.

Step-by-step explanation:

When we are given a equation, it is possible to multiply or divided all of the terms of the equation by a factor.

In this question:

We are given:

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

And end up with:

[tex]\frac{x}{4} + 1 = -3[/tex]

Which means that all terms of the equation were divided by 4.

Answer:

14cm

Step-by-step explanation:

Volume of the pyramid = Base area × height/3

V = BH/3

Base area = 14×width

Height= 9cm

Volume = 168cm³

Substitute into the formula

168 = 4w×9/3

36w = 168×3

36w = 504

w = 14cm

Hence the width of the pyramid is 14cm

7.8^5

Step-by-step explanation:

Answer: 457.3

Step-by-step explanation:

[tex]V=\frac{lwh}{3}[/tex]

[tex]V=\frac{14*14*7}{3}[/tex]= 457.3

Answer:

V= 1568 in^3

Step-by-step explanation:

B = 14^2 = 196

896 = 14^2 + 2(14) (l)

896 = 196 + 28 (l)

700 = 281 l

25 = l

7^2 + b^2 = 25^2

49 = 625

24

1/3 (196)(24) = 1568

Answer:

the area is 32

Step-by-step explanation: 2 x 2 x 2 x 2 x 2= 32

Answer:

-390 is your answer

Answer:

Step-by-step explanation:

PEDMAS - Parenthesis , Exponents ,  Division, Multiplication , Addition and subtraction.

(-9 - 6 *5) *10 = (-9 - 30) *10

                     = -39 *10

                     = -390

Answer:x=-7

Step-by-step explanation:

Answer:

In this problem you have to get rid of the 13 so you take the opposite of the number which is -13 and subtract it by 13 and when you do this you have to do the same thing on the other side so you would do 48-13 and that would give you get 35 so -5x=35. This is not the same because on B it says positive 5x, and on A it is negative 5x.

Answer:

x - 80

Step-by-step explanation:

"80 less than x"

__________________

We have the expression 80 less than x. X has no artifical value therefore we do nothing with it. Based off of the wording of the sentence, it says that the total of this unknown number is 80 less than x. Meaning the 80 has been subtracted by x to get this unknown number. Therefore,

x - 80

Answer:

1/9

Step-by-step explanation:

(1/3)/3 = 1/9

Answer: The number is =5

Step-by-step explanation:

21  +                  3X                              =         ("Difference means subtract.)                           2X

Twenty-one more than three times a number is equal to the difference between 46 and twice the number

Then write the proper equation:     21+3x= 46-2x.

Next get rid of the smaller "x" so 3x+2x=46-25

solve X

5x=25

x=5

Answer:

x= -6

y= -5

Step-by-step explanation:

(x,y) = (-6, -5)

Answer:

(-6,-5)

x=-6

y=-5

Step-by-step explanation:

9x-7y=-19

5x-3y=-15

When solving with elimination, you multiply both equations by a number to get two terms to cancel each other out.

We can try to get the y's to cancel out. The LCD of 7 and 3 is 21, so we multiply one equation by 3 and another by -7 (to get one -21y and one 21y)

{9x-7y=-19}*3=

27x-21y=-57

{5x-3y=-15}*(-7)=

-35x+21y=105

Now, we combine the two equations.

27x-21y=-57

-35x+21y=105

-8x=48

Now, solve for x.

-8x=48

x=-6

Now we can plug x into one of the original equations to get y.

I will use 9x-7y=-19.

9(-6)-7y=-19

-54-7y=-19

Add 54 to both sides.

-7y=35

y=-5

We can put these values into an ordered pair: (-6,-5).
