PLEASE HELP i got the wrong answers does anyone know how to solve math this way?! please answer 1 and 2 with explanation, using the X method

Answer:

Todd is wrong.

Step-by-step explanation:

Basically, the ratio of boys to girls is 3:5 12: x. Let's represent the number of girls with x. If we cross multiply, 5×12÷3=20. Therefore there are 20 girls and 32 students in total.

The obtained coordinate points to plot the graph are matching with graph C. Therefore, option C is the correct answer.

Given that, a car's odometer starts at 25 miles and for every 25 miles traveled, 1 gallon of gas is used.

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

Let the number of miles traveled be y, and the gallons of gasoline used be x.

Now, the equation for the given situation is y=25x

By substituting x = 1, 2, 3, 4, 5,....we get

y = 25(1) =25

y = 25(2) =50

y = 25 (3) =75

y = 25 (4) =100

So, the coordinates to plot the graph are (1, 25), (2, 50), (3, 75) and (4, 100) and so on.

The obtained coordinate points to plot the graph are matching with graph C. Therefore, option C is the correct answer.

Answer:

The prime factorization of 54 = 2 × 3 × 3 × 3 = 2 × 3.

Step-by-step explanation:

Factor 54 into two numbers, then factor each of those factors as much as possible until you can't factor a number.

54

=  = ( 9 ) ⋅ ( 6 )  

= ( 3 ⋅ 3 ) ⋅ ( 2 ⋅ 3 )

This is the prime factorization of 54.

Answer:

Step-by-step explanation:

y = x + 3

so when x = 0 then y= 0 + 3 which means, when x = 0 then y=3

so

x    y

0    3  y=0+3

1     4   y=1+3

2    5   y=2+3

3    6    y=3+3

4    7     y=4+3

5    8    y=5+3

Answer:

See pic below.

Step-by-step explanation:

Create a table of values by letting x equal some numbers such as 0, 1, 5, 7. You can use others, too.

You started filling out the table correctly.

Find the corresponding y-coordinates and write them in the table.

Then plot each point on the graph using a dot.

Then connect the dots with a line.

Answer to -1/3x-1+x2 in standard form:

x²-1/3x-1

Step-by-step explanation:

9x - 2 = 5x + 54

9x - 5x = 54 + 2

4x = 56

x = 14

(9x - 2) + (10y + 6) = 180

(9 · 14 - 2) + 10y + 6 = 180

126 - 2 + 10y + 6 = 180

130 + 10y = 180

10y = 180 - 130

10y = 50

y = 5

Answer:

[tex]\displaystyle f(x) = \ln\left( 1 + x^2\right)[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle e^{f(x)} = 1 + x^2[/tex]

And we want to find f(x).

We can take the natural log of both sides:

[tex]\displaystyle \ln\left(e^{f(x)}\right) = \ln\left( 1 + x^2\right)[/tex]

Recall that ln(aᵇ) = bln(a). Hence:

[tex]\displaystyle f(x) \ln(e) = \ln\left ( 1 + x^2\right)[/tex]

By definition ln(e) = 1. Therefore:

[tex]\displaystyle f(x) = \ln\left( 1 + x^2\right)[/tex]

Answer:

D

Step-by-step explanation:

because the angles are across from each other, they are equivalent

you would set up the equation like this

8x - 8 = 7x + 8

then you could add 8 to each side

8x = 7x + 16

then subtract 7x from each side

x = 16

Step-by-step explanation:

dude it doesn't exist 49 is an odd number

Answer:

-8 <_ x < -3

-7 <_ y < -2

Step-by-step explanation:

closed dot means it includes that number so in this case x is least than or equal to -8 and open dot means it doesn't include that value so x is less than -3 and does NOT include -3

and for the y value it's pretty self explanatory if u just count it (i might be off by a little cuz the photo quality is kinda fuzzy but i hope u get the gist!)

y is equal to (0,-5) and there is no slope so it's a straight line.

Answer:

3/4 would be .75

Step-by-step explanation:

1/4 would be .25 because .25x4=1. Because the denominator is a 4 you are trying to find a number that when multiplied 4 times would equal 1 or 4/4.

Answer:

3/4 cannot be .34 because that is not what it is equal to when converted to hundredths.

Step-by-step explanation:

The decimal 0.34 is in the value hundredths. 3/4's value when converted to hundredths is 75/100 or 0.75. We get this by multiplying 3 and 4 by the same factor that brings 4 to 100, which is 25.

So, 4*25=100(denominator), and 3*25=75(numerator). The decimal value is 0.75. Therefore, 3/4 cannot be 0.34 because the values are not the same.
