(ASAP) I really need help on this I have a C- in Math right now and( I NEED TO GET UP MY GRADE) plsssss

Answer:

C

Step-by-step explanation:

324 = 4 [tex](3)^{2x}[/tex] ( divide both sides by 4 )

81 = [tex]3^{2x}[/tex] , that is

[tex]3^{4}[/tex] = [tex]3^{2x}[/tex]

Since bases on both sides are equal, both 3, then equate exponents

4 = 2x ( divide both sides by 2 )

2 = x → C

Step-by-step explanation:

1/5= 8-5/n-2

Answer:

1) A) 64 tickets

  B) $11

2) A) 20 rides

Step-by-step explanation:

1) a) set y to 37 because they made 37 dollars

37 = 0.50x + 5

32 = 0.50x.........subtract 5 from both sides

64 = x..................divide both sides by 0.50 to get x by itself

b) set x to 12 because x is the amount of ride tickets they bought

y = 0.50(12)+ 5

y = 6 + 5............multiply 12 by 0.50

y=11......................add

2) a) set both equations equal to each other to see when they will be equal

0.50x + 5 = 0.75x

0.50x = 0.75x - 5..........subtract 5 from both sides

0.50x - 0.75x = - 5........subtract 0.75x from both sides

-0.25x = - 5......................combine like terms

x=20...................................divide both sides by -0.25 to isolate x

Answer:

20

Step-by-step explanation

trust me

Answer:

x = 20

Step-by-step explanation:

(5x + 35) + 45 = 180

These angles are opposites to each other so you know that together they equal 180.

Start off by adding 35 and 45. This gives you...

5x + 80 = 180

Then subtract by 80 giving you...

5x = 100

Then divide by 5. This gives you...

x = 20

Answer:

2 ^ 3(x+1)

Step-by-step explanation:

Assuming  2^(4x+4) / 2 ^(x+1)

when bases are equal and exponents are in division it becomes subtraction

=> 2 ^ (4x + 4 - (x + 1) )

=> 2 ^ (4x + 4 -x - 1)

=> 2 ^ (3x + 3)

=> 2 ^ 3(x+1)

=> [tex]2^{3(x+1)}[/tex]

Answer:

30:40

Step-by-step explanation:

Item A:  item B :  total

3                 4        3+4

3                  4          7

The total is 70

70/7 = 10

Multiply each item by 10

Item A:  item B :  total

3*10           4 *10     7*10

30                 40       70

Answer:

30 and 40

Step-by-step explanation:

3 : 4  means 3 out of every 7 objects and 4 out of every 7.

[tex]\frac{3}{7} (70) = 30[/tex]

[tex]\frac{4}7} (70) = 40[/tex]

Answer:

Step-by-step explanation:

An "undefined slope" is a vertical line going through the x axis at 5.  The slope is undefined since there is no change in x for all values of y.  The means the slope, which is the change in y divided by the change in x, would be a fraction with a zero denominator.  This makes it undefined.  

One value of x, in this case x=5, will include all possible values of y.  There is no y-intercept, but the line has an x-intercept of 5.

Univariate statistical tests are most appropriate for testing hypotheses that compare the characteristics of two groups is False

Univariate statistical tests are statistical test that are used to observe a single variable. We can have one or more independent variables but we study only one dependent variable.

So, univariate statistical tests are not most appropriate for testing hypotheses that compare the characteristics of two groups.

Answer:

(-8.-9) and (14,13).

Step-by-step explanation:

y=x-1

y=117/x-5

As the 2 terms in x are both equal to y:

x-1 = 117/x-5

(x-1)(x-5) = 117

x^2 - 6x + 5 - 117 = 0

x^2 - 6x - 112 = 0

(x + 8)(x - 14) = 0

x = -8, 14.

When x = -8, y = -8-1 = -9

When x = 14, y = 14-1 = 13.

The required coordinate points are (-8.-9) and (14,13).

Given the following equations

y=x-1

y=117/x-5

Equating both function will give

x-1 = 117/x-5

(x-1)(x-5) = 117

x^2 - 6x + 5 - 117 = 0

x^2 - 6x - 112 = 0

(x + 8)(x - 14) = 0

x = -8, 14.

When x = -8, y = -8-1 = -9

When x = 14, y = 14-1 = 13.

Hence the required coordinate points are (-8.-9) and (14,13).

Step-by-step explanation:

Answer:

0.4*0.5=0.2

Step-by-step explanation:

each shaded area is 10 by something, so we can assume this model is representing decimals

the other sides are 4 and 5, and it is in 10, so it is 0.4*0.5

0.4*0.5=0.2

Answer:

36a and 2x-3.that is the answer

Answer:

Step-by-step explanation:

Slope intercept form: y = mx +b

10x - 7y = -8

      -7y = - 10x - 8

Divide the equation by (-7)

[tex]\dfrac{-7y}{-7}=\dfrac{-10x}{-7} +\dfrac{-8}{-7}\\\\\\y =\dfrac{10}{7}x+\dfrac{8}{7}[/tex]

Answer:

P = (1,4)

Step-by-step explanation:

First turn both equations to slope intercept form (y=mx+b).

5x - y = 1

Subtract 5x on both sides to get -y = -5x + 1, and since we want the y to be positive simply flip all the signs to get

y = 5x - 1.

x + 2y = 9

Subtract x on both sides to get 2y = -x + 9, then divide both sides by 2 to get

y = -1/2x + 9/2.

Now you can graph the two lines and see where they intercept each other. (I graphed them above for you⤴⤴⤴).
