Greeley [361]3 years ago

7 0

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = $\frac{1}{2}$ , thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute (- 4, - 9) into the partial equation

- 9 = - 2 + c ⇒ c = - 9 + 2 = - 7

y = $\frac{1}{2}$ x - 7 ← equation of line

Oxana [17]

Answer:

b= -48

Step-by-step explanation:

by transposing,

43=59+b/3

b/3+59=43

b/3=43-59

b/3= -16

b= -16×3

b= -48

therefore the answer is b= -48

The last term of an arithmetic sequence is 14 and the ninth term is -1. Find the first four

Olegator [25]

Answer:

Step-by-step explanation:

where n is the number of terms, a1 is the first term and an is the last term. The sum of the first n terms of an arithmetic sequence is called an arithmetic series . Example 1: Find the sum of the first 20 terms of the arithmetic series if a1=5 and a20=62 .An arithmetic sequence is a sequence where the difference between any two consecutive terms is a constant. ... As with any recursive formula, the initial term of the sequence must be given. An explicit formula for an arithmetic sequence with common difference d is given by an=a1+d(n−1) a n = a 1 + d ( n − 1 ) .

Anyone know how to do this?

Lera25 [3.4K]

Answer:

Part A) 25

Part B) 225

Step-by-step explanation:

Part A

The slope of the graph gives us the mile per gallon of the car.

Recall that the slope of the graph is rise over run.

$m = \frac{200}{8} = 25$

Therefore car gets 25 miles per gallon

Part B) Since we know the slope of the direct variation line, we substitute into y=kx to get:

$y = 25x$

To find the number of miles the car travels using 9 gallons, we substitute x=9 to get:

$y = 25 \times 9$

This gives us 225 miles
