Answer:

9 hours worked after school and 4 hours worked on saturday

Step-by-step explanation:

x = amount of hours worked after school

y = amount of hours worked on saturday

x + y = 13 or x = 13 - y

and

3x + 4y = 43

plug:

3 · (13 - y) + 4y = 43

39 - 3y + 4y = 43

y = 4

plug:

x = 13 - y

x = 13 - 4 = 9

9 hours worked after school and 4 hours worked on saturday

What is the question? I am confused?

Answer:

x = 49

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{DN}{KJ}[/tex] = [tex]\frac{DG}{KM}[/tex] , substitute values

[tex]\frac{5}{35}[/tex] = [tex]\frac{8}{x+7}[/tex] ( cross- multiply )

5(x + 7) = 280 ( divide both sides by 5 )

x + 7 = 56 ( subtract 7 from both sides )

x = 49

Answer:

37.5 miles per gallon

Step-by-step explanation:

450/12 =37.5

this is around about how much it is

Answer:

37.5mi/g

Step-by-step explanation:

So if she's going 950mi total with a 12g tank, and is almost empty at 450mi, you would do 450mi / 12g which would be 37.5mi/g

Answer:

Below.

Step-by-step explanation:

–10m4n3 + 8m2n6 + 3m4n3  – 2m2n6 – 6m2n6

= 8m2n6 – 2m2n6 – 6m2n6 – 10m4n3 + 3m4n3

= 8m2n6 - 8m2n6 – 7m4n3

= –7m4n3.

It is a mononomial.

Answer:

[tex]\frac{\sqrt{70} }{5}[/tex]

Step-by-step explanation:

= f( g(2) )

= 3(2x + 1) + 1

= 6x + 3 + 1

= 6x + 4

= 6(2) + 4

= 12 + 4

= 16

f(g(2)) = 16

Step-by-step explanation:

to find the missing side length we need to use the invisible triangle that is kind of cut off in the top left corner.

it is a right-angled triangle, and the missing side is the Hypotenuse (baseline). therefore, we use Pythagoras.

now, can we get the invisible side lengths of this triangle ?

yes, because the complete figure including the invisible triangle is s perfect rectangle with 2 equal lengths and 2 equal widths.

so, the complete rectangle side on the left would also be 5. but we see only 2. so the invisible part is 5-2=3.

and the complete rectangle side in the top would also be 8. but we see only 4. so the invisible part is 8-4=4.

so, with Pythagoras,

unknown side² = 3² + 4² = 9 + 16 = 25.

unknown side = 5

and now the perimeter is

P = 2 + 8 + 5 + 4 + 5 = 24

Answer:

y-intercept = -6

Step-by-step explanation:

y-intercept is the value of "y" where a line meets the Y coordinate.

The equation of the line

The linear function given to us is a straight line of equation:

[tex]\boxed{\mathsf{3x-4y=24}}[/tex]

We have two methods to determine the y intercept of the given line

(Intercept form)

The intercept form will benefit us with not only the y-intercept but also the x-intercept.

If a line makes an x-intercept "a" and a y-intercept "b", it's equation in intercept form is given by:

[tex]\boxed{\mathsf{\frac{x}{a} +\frac{y}{b} =1}}[/tex]    . . . . . . . .. . . (¡)

Our main motive here is to get a 1 on one side and have separate denominators for x and y.

PROCESSING OUR CONVERSION:

[tex]=>\mathsf{3x-4y=24}[/tex]

taking 24 to the denominator on the LHS:

[tex]\implies\mathsf{\frac{3x}{24} -\frac{4y}{24} =1}[/tex]

reducing the fractions to their simplest form:

[tex]\implies\mathsf{\frac{x}{8} -\frac{y}{6}=1}[/tex]

getting a plus in between the two fractions and taking the leftover minus to 6 of " [tex]\frac{y}{6}[/tex]"

[tex]\implies\mathsf{\frac{x}{8} +\frac{y}{-6}=1}[/tex]

On comparing it with eqn. (¡), we get

a = 8 and b = -6

which are the x and y intercepts respectively

Since, the question's only asked for the y-intercept

ANSWER:

y-intercept = - 6

- - - - - - - - - - - - - - - - -- - - - - - - - - - - - - - - - - - - - - - - - - - -

(slope-intercept form)

The given equation is in standard form. To convert it into slope-intercept you simply have to isolate y.

CONVERSION:

[tex]\implies \mathsf{3x-4y=24}[/tex]

taking y to the RHS and getting 24 to the LHS

[NOTE: Signs change in doing so]

[tex]\implies \mathsf{3x-24=4y}[/tex]

dividing both the sides by 4

[tex]\implies \mathsf{\frac{3x}{4} -6=y}[/tex]

This is the equation in slop-intercept form!

When a line meets the Y-axis it's x coordinate becomes 0.

[Check the attachment]

Substituting x with 0

[tex]\implies \mathsf{0-6=y}[/tex]

[tex]\implies \mathsf{-6=y}[/tex]

ANSWER:

x is 0 when y is -6.

Implies that the y intercept of the line is -6

Answer:

Step-by-step explanation:

To find the y-intercept, set x=0 and evaluate the function.

  f(0) = -3/(0 -4) = 3/4

The y-intercept is (0, 3/4).

__

To find the x-intercept(s), set f(x) = 0 and solve for x.

  0 = -3/(x^2 -4)

  0 = -3 . . . . . . . . . . multiply by (x^2 -4), x ≠ ±2

There are no values of x that will make this true. There are no x-intercepts.

_____

Additional comments

In general, you find the x-intercepts of a rational function by finding the zeros of the numerator. Here, the numerator is -3, so cannot ever be zero.

I find a graphing calculator to be a useful tool for showing where to look for x-and y-intercepts. The attached graph shows y=0 (the x-axis) is a horizontal asymptote, so there are no x-intercepts.
