Answer:

is it -180?

I don't remember most of this stuff!

sorry if its wrong

Step-by-step explanation:

Answer:

y = 2016 - 112x

Step-by-step explanation:

because he is paying 112 dollars each month for 18 months

y= 2016 -112x

for instance, he paid it for 6 months we would say

y = 2016 - 112(6)

y = 2016 - 672

y = 1334

so, y = 2016 - 112x

Answer:

780 ≥ 58.53x + 566.83

Step-by-step explanation:

He has $780 that he can spend, so the total must be less than or equal to 780.

Let x = number of biking outfits.

Costs:

Bicycle: $490.50

Reflectors: 4 × $14.98 = $59.92

Gloves $16.44

Outfits: $58.53x (The cost of x outfits is 58.53x)

The total he spends is:

490.5 + 59.92 + 16.44 + 58.53x =

= 58.53x + 566.86

This total has to be less than or equal to $780.

58.53x + 566.86 ≤ 780

This can be written as

780 ≥ 58.53x + 566.83

Answer:

From the Soldier's point of view, the American Civil War was not a continuous battle. Instead, it was long monotonous marches and long residency in camps punctuated by the terror and chaos of combat. When winter set in and the campaigning season came to a close, most Soldiers counted on a long, cold stay in a winter camp. The four log cabins at the center of the Army Heritage Trail represent the types of buildings which Soldiers in both the Union and the Confederate Armies spent the long dreary months of winter. The cabins are modeled after images from the USAHEC collection, including the Army of the Potomac's winter camp at Brandy Station and the Confederate camp at Centerville

Answer:

Option 2 [tex]x[/tex] = 15, [tex]y[/tex] = 3

Step-by-step explanation:

Vertical angles are equivalent. Thus [tex]4x+10y[/tex] = 90. To solve for [tex]x[/tex], we set [tex]6x[/tex] = 90, since adjacent angles equal 180. This gives us 15 as x. Plugging 15 into the first equation we get that y is equal to 3.

The amount of you swam is +15 feet and your friend swam is -6 feet.

Given that you move forward 15 feet and your friend is not a strong swimmer, so he moves back 6 feet.

The arithmetic operators means performing an addition, subtraction, multiplication, division, exponentiation, and modulus operations.

It is given that you move the forward that means you move in positive direction.

So, you move forward means you move +15 feet.

It is also given that your friend is not a strong swimmer, so he moves back that means he move in negative direction.

So, your friend moves backward means he move -6 feet.

Hence, you move forward 15 feet is +15 feet and your friend is not a strong swimmer, so he moves back 6 feet is -6 feet.

The correct option is (C) The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).

Given that the following table represents  the linear function f(x), and the equation represents the linear function g(x) :

x                   0                     2                          4

f(x)                1                      9                         17

and g(x) = 3x + 1 .........(1)

We have to compare the y-intercepts and slopes of the linear functions f(x) and g(x) and choose the answer that best describes them.

From the graph, we note that (0, 1), (2, 9) and (4, 17) are three points on the line graph of function f(x).

We know that, the slope of any line having two points (a, b) and (c, d) on it is given by

m = d-b/c-a

So, the slope of the line of f(x) is

m = 9-1/2-0

m = 8/2

⇒ m = 4

Since the line of f(x) passes through the point (0, 1), so its equation will be

f(x) -1 = m(x-0)

⇒ f(x) -1 = 4(x-0)

⇒ f(x) -1 = 4x

⇒ f(x) = 4x+1 ........... (2)

The slope-intercept form of the equation of a line is y = mx + c, where m is the slope and c is the y-intercept of the line.

Comparing equation (2) and (1) with the slope-intercept form, we get

slope of f(x) = 4  and  y-intercept of f(x) = 1 and

slope of g(x) = 3  and  y-intercept of g(x) = 1.

Thus, the slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).

Option (C) is CORRECT.

4 cups of pasta are used per cup of sauce.

Given,

Greta uses 3 cups of pasta for every 3/4 cup of sauce.

We need to find how much pasta she uses per cup of sauce.

Example:

12 apples = 2 basket ____(1)

For 5 baskets:

We need to make 2 baskets = 5 baskets.

We can divide by 2 and multiply 5 on both sides on (1).

5/2 x 12 apples = 5/2 x 2 baskets

30 apples = 5 baskets.

We have,

3 cups of pasta = 3/4 cup of sauce

We need to make 3/4 cup of sauce as 1 cup of sauce.

Multiply 4/3 on both sides.

4/3 x 3 cups of pasta = 4/3 x 3/4 cup of sauce

4 cups of pasta = 1 cup of sauce

Thus 4 cups of pasta are used per cup of sauce.

The sum of an infinite geometric series is twice its first term then the common ratio(r) be 1/2.

An infinite geometric series is the outcome of an unlimited geometric sequence. This series wouldn't have a finish. It is possible to calculate the sum of all finite geometric series. The terms in the sequence will grow steadily larger, but adding the larger numbers together will not provide a solution if the common ratio of an infinite geometric series is greater than one.

Given: S = 2a₁

a₁ be the first term

r be the common ratio

Let the equation be S = a₁/1-r

2a₁ = a₁/1-r

substitute the values in the above equation, we get

2 = 1/1-r

2 - 2r = 1

2r = 1

Answer: x = -10

Step-by-step explanation:

Answer:

(- 10, 10 )

Step-by-step explanation:

6x + 5y = - 10 ( subtract 6x from both sides )

5y = - 10 - 6x → (1)

3x + 5y = 20 → (2)

substitute 5y = - 10 - 6x into (2)

3x - 10 - 6x = 20

- 3x - 10 = 20 ( add 10 to both sides )

- 3x = 30 ( divide both sides by - 3 )

x = - 10

substitute x = - 10 into (2) and solve for y

3(- 10) + 5y = 20

- 30 + 5y = 20 ( add 30 to both sides )

5y = 50 ( divide both sides by 5 )

y = 10

solution is (- 10, 10 )

In geometry line segment is a part of a line that is bounded by two end points, and contains every point on the that is between end points.

Given, coordinates of M(-3,-2)

and coordinates of P(9,13)

so we have,

x₁ = -3

y₁ = -2

x₂ = 9

y₂ = 13

Also we know that MN is 1/3 of MP

⇒ MN/MP = 1/3 = mn

here, m= 1 and n=3

Let the coordinates of N be (x,y)

Therefore,

(x,y)  = (nx₁+mx₂)/(m+n) , (ny₁+my₂)/m+n

⇒ (x,y) = (3(-3)+1(9)/1+3) , (3(-2)+1(13)/1+3)

⇒ (x,y) = (-9+9/4) , (-6+13/4)

⇒ (x,y) = (0,7/4)
