Answer:

y = -2x + 4

Step-by-step explanation:

Looking at the graph, we can find the y-intercept by seeing where 0 meets with the y axis. That means our y-intercept is 4. To find the slope we can pick two coordinates from the graph and use the slope formula. Rise/Run

Let's pick the coordinates: (1,2) and (2,0).

Plug it in:

0 - 2 / 2 - 1 = m

0 -2 / 2 - 1 = -2/1

-2/1 = -2

m = -2

Find the explicit formula for a 1 =-4,a n =a n-1 +9,n>=2
Mrrafil [7]

Given:

a_1=-4 and a_n=a_{n-1}+9 where n\geq 2.

To find:

The explicit formula for the given recursive formula.

Solution:

We know that recursive formula of an AP is:

a_n=a_{n-1}+d

Where, d is the common difference.

We have,

a_n=a_{n-1}+9

Here, d=9.

The first term of the AP is a_1=-4.

The explicit formula for an AP is:

a_n=a_1+(n-1)d

Substituting a_1=-4 and d=9, we get

a_n=-4+(n-1)9

a_n=-4+9n-9

a_n=-13+9n

Therefore, the required explicit formula for the given sequence is a_n=-13+9n.

Marcus is 5 19/24 feet tall. Ben is 5 9/16 feet tall. Which of the two boys is taller?
Ksju [112]

well, Marcus and Ben are both 5 feet tall and a little bit more, Marcus is 19/24 more and Ben is 9/16 more, so the 5's in the fraction are the same, so which one is larger, 19/24 or 9/16?

we can simply put both fractions with the same denominator, by <u>multiplying one by the other's denominator</u>, so let's proceed,

\bf \stackrel{\textit{\large Marcus is taller}}{5~feet + \left( \cfrac{19}{24}\cdot \cfrac{16}{16}\implies \boxed{\cfrac{304}{384}} \right)}\qquad \qquad \qquad \stackrel{\textit{\large Ben}}{5~feet + \left( \cfrac{9}{16}\cdot \cfrac{24}{24}\implies \boxed{\cfrac{216}{384}} \right)}

Simplify 6(x + 2) + 7.
Elina [12.6K]

Answer:

6x+19

Step-by-step explanation:

First thing first, we need to multiply the 6 into the equation. We do this by multiplying the x and 2 by 6.

6(x+2)+7

Multiply

6x+12+7

Now we need to combine like terms by adding the 12 and 7

6x+19

There it is simplified.
