5 (x + 5) <85
For this case, the first thing we will do is clear the expression step by step.
Step 1:
Pass the five to divide:
5 (x + 5) <85
(x + 5) <85/5
(x + 5) <17
Step 2:
Pass the 5 inside the parenthesis to subtract:
(x + 5) <17
x <17-5
x <12
The answer is:
x <12
equivalently:
x: (-inf, 12)
Answer:
x <12
x: (-inf, 12)

Can someone help me with this?

Anna35 [415]

Answer:

Let 'a' be the first term, 'r' be the common ratio and 'n' be the number of terms

Series = 2+6+18.......= 2+2•3¹+ 2•3².......= 728

Now,

$Sum = \frac{a( {r}^{n} - 1) }{(r - 1)} \\$

So,

$\frac{a( {r}^{n} - 1)}{(r - 1)} = 728 \\ \frac{2( {3}^{n} - 1) }{(3 - 1)} = 728 \\ \frac{2( {3}^{n} - 1) }{2} = 728 \\ {3}^{n} - 1 = 728 \\ {3}^{n}=728+1\\ {3}^{n} = 729 \\ {3}^{n} = {3}^{6} \\ \boxed{ n = 6}$

Therefore, number of terms is 6

6 is the right answer.

Explain your answer so I can understand

Dmitrij [34]

If all the sides equal(1.2mi and he’s riding on all sides) then he would have to ride his path 6.25 times because 30 divided by 4.8 is 6.25 if he’s only riding on one side then he would ride his path 25 times because 30 divided by 1.2 is 25

Identify the vertex and the y-intercept of the graph of the function.

skad [1K]

Answer:

Step-by-step explanation:

vertex-form equation for a vertical parabola with vertex (h,k):

y = a(x-h)² + k

y = -1.5(x+2)²

vertex (-2,0)

y-intercept = -1.5(0+2)² = -6
