The distance between the city and the house is 260 miles.

A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 = 15, for instance. There are different types of equations like linear, quadratic, cubic, etc.

t              d

1             195

2            130

2.5         97.5

The distance will be calculated by the equation of the line,

y = mx + c

m = ( 130 - 195 ) / ( 2 - 1 )

m = -65

y = -65x + c

195 = -65 + c

c = 260miles

Hence, the distance will be 260 miles.

9, 30, 93, 282, 849

====================================================

Explanation:

The first term is 9 because of the notation [tex]a_1 = 9[/tex]

To get the second term, we use the recursive rule given to us which is

[tex]a_n = 3a_{n-1} + 3[/tex]

I recommend using parenthesis to separate things like this

[tex]a_n = 3(a_{n-1}) + 3[/tex]

If n = 2, then,

[tex]a_n = 3(a_{n-1}) + 3\\\\a_2 = 3(a_{2-1}) + 3\\\\a_2 = 3(a_{1}) + 3\\\\a_2 = 3(9) + 3\\\\a_2 = 27 + 3\\\\a_2 = 30[/tex]

The second term is 30.

You can use the same idea as above to find the third term, or you can use this slightly different approach

[tex]\text{third term} = 3*(\text{second term}) + 3\\\\\text{third term} = 3*(30) + 3\\\\\text{third term} = 90 + 3\\\\\text{third term} = 93[/tex]

To generate any new term, we first triple the previous term and then add on 3.

Answer:

25%

Step-by-step explanation:

Let George's salary = $50,000 per year

If his salary dropped by 20%, then his salary would be 80% of his previous salary (as 100% - 20% = 80%).

Convert 80% to a decimal: 80% = 80/100 = 0.8

Therefore, 80% of 50000 = 0.8 x 50000 = $40,000

We wish to increase his salary back to the original amount of $50,000.

The difference between the two salaries is : 50000 - 40000 = 10000

Therefore, we need to calculate the percentage that $10,000 is of $40,000.

⇒ (10000 / 40000) x 100 = 25%

So George's salary needs to increase by 25% to get back to where it was before the salary drop.

The term n is the initial amount that the television is to be sold.

We are told that the television in this case is to be sold at a discount piece. The implication of this is that there is something that has to be removed from the price of the television as it is sold.

We are told that what they are to remove from the price of the television is about $75  and that when this is done, the price of the television would be about $300. Thus n is the original price of the television.

The variable n represents the initial value of the television

From the question, we have the following parameters that can be used in our computation:

Amount off = $75

New price = $300

When represented as the equation, we have

n - 75 = 300

Add 75 to both sides of the equation

So, we have the following representation

n = 375

This means that the initial price of the television is $375

Step-by-step explanation:

(-3,5) and (x,y)

Slope = (y - 5)/[x - (-3)] = (y - 5)/(x + 3)

(y - 5)/(x + 3) = -1/4

y - 5 = -1/4(x + 3)

y - 5 = (-1/4)x - 3/4

y = (-1/4)x - 3/4 + 5

y = (-1/4)x + 17/4.

Answer:

The answer should be 236g.

Step-by-step explanation:

If we take the amount of flour used for the cake as 'x,' the flour used to make the scones would be (500-x)×2/3 as 2/3 of the remaining is used for the scones.

We know that 60g more flour is used for the cake.

So,

x-60=(500-x)×2/3

Cross multiply, and brng the 3 to the other side.

3(x-60)=(500-x)2

3x-180=1000-2x

Bring the x-terms to one side and the numbers to one side.

3x+2x=1000+180

5x=1180

Divide both sides by 5 to find x(the amount of flour used to make the cake)

Therefore,

x=236g

Answer:

Yes, they are equivalent expressions, by the Associative Property

Step-by-step explanation:

Both of these expressions are equal to:

4a + 5a + 3c

(and then, 9a + 3c)

This is all adding so you can add them all up without any of the parentheses. In the question at first the parentheses are grouping together the 5a and 3c, but in the second expression they are wrapped around the 4a and 5a. But in both expressions the order of the three terms does not change. Only the grouping changes. The terms are grouped differently, but the order DOES NOT change. This is Associative property. If the order changes it is Commutative property.

Answer:

g(x) = 3^x -7

Step-by-step explanation:

In an exponential function like this, the constant at the end of the function represents the vertical shift. This means that the original function is shifted 2 units up. So, 9 units lower than +2 is -7. Thus, the new function, g(x), is g(x)=3^x - 7.
We can prove that g(x) is 9 units lower through y-intercepts. The function f(x) has a y-intercept of 3 and g(x) is -6. Since -6 is 9 lower than 3, we know that there is a 9 unit difference between the functions.

Given :-

To Do :-

Solution :-

Given equation to us is ,

→ y = 3x -1

As we know that , the slope intercept form of the line is ,

→ y = mx + c

where m is the slope and c is the y intercept .On comparing both , we have ,

So the graph will cut the y axis at (0,-1) . And will have a slope of 3 .

When y coordinate is 0 ,

So that ,

→ x - 0 / 0 -(-1) = 3

→ x/0+1 = 3

→ x/1 = 3

→ x = 3

Hence one other point is (3,0 ).

Now we may plot the graph using these two points (3,0) and (0,-1) .
