Solve for x. The polygons in each pair are similar.
Nonamiya [84]
If each is similar, then 6 times (5) = 30
                     therefore 8 times (5) = 6X - 8
                                       40 = 6X - 8
add 8 to both sides        48 = 6X
divide by 6                      8 = X

SSSSS [86.1K]

Answer:

The y-intercept is (0,-2)

Step-by-step explanation:

we know that

The <u><em>x-intercept</em></u> is the value of x when the value of y is equal to zero

The <u><em>y-intercept</em></u> is the value of y when the value of x is equal to zero

In this problem we have that

The graph crosses the x axis at negative 10 and crosses the y axis at negative 2.

therefore

The x-intercept is the point (-10,0) and the y-intercept is the point (0,-2)

Write a recursive formula for the sequence<br> 1/4,1/2,3/4
Serjik [45]

Answer:

a_n = a_ {n - 1} +  \frac{1}{2} , \: a_1 =  \frac{1}{4}

Step-by-step explanation:

The given sequence is:

\frac{1}{4}, \frac{1}{2}, \frac{3}{4}

The first term of this sequence is

a_1 =  \frac{1}{4}

There is a common difference of d=½

The recursive formula is:

a_n = a_ {n - 1} + d

We substitute the common difference to get:

a_n = a_ {n - 1} +  \frac{1}{2}

$10 per guest for food and $5 per guest for drink.
