Answers

Answer 1

Answer:

7, 4, 1, and -2.

Step-by-step explanation:

Our recursive rule is:

[tex]f(1)=7\!, f(n)=f(n-1)-3[/tex]

Where n is the nth term.

So, our first term will be f(1). As defined, this is 7.

Our second term will be f(2). We will use the recursive formula. Substituting 2 for n yields:

[tex]f(2)=f(2-1)-3[/tex]

Subtract:

[tex]f(2)=f(1)-3[/tex]

We know that f(1) is 7. Substitute:

[tex]f(2)=7-3=4[/tex]

Hence, the second term is 4.

We will do the same thing for the third term. Substitute 3 for n:

[tex]f(3)=f(3-1)-3[/tex]

Subtracting yields:

[tex]f(3)=f(2)-3[/tex]

We know that f(2) is 4. So:

[tex]f(3)=4-3=1[/tex]

Hence, the third term is 1.

Finally, we will do the same thing. Substitute 4 for n to find the fourth term:

[tex]\begin{aligned} f(4)&=f(4-1)-3 \\ f(4)&=f(3)-3 \\ f(4)&=1-3 \\ f(4)&=-2\end{aligned}[/tex]

Hence, the fourth term is -2.

Therefore, our first four terms are 7, 4, 1, and -2.

Answer:

3. y = 4

4. y = 40

Step-by-step explanation:

3. To find y, input the value of 2 for x in the equation y = 3x - 2.

y = 3(2) - 2

y = 6 - 2

y = 4

y is 4 when x is 2.

4. To find the answer we first have to make an equation in y=mx + b form, where b is the y-intercept and m is the slope. We know that the y-intercept is -5 because the table tells us that when x is zero, y is -5. So, we can use the y-intercept and a point In this example I will use point (6, 13)) to find the slope:

Input the values you know into the equation:

13 = 6m - 5

Add 5 to both sides to isolate the 6m:

18 = 6m

Divide both sides by 6 to isolate the m:

3 = m

Our slope is 3. Now that we know the slope and y-intercept, we can make our equation:

y = 3x - 5

We can use this equation to find y when x is 15:

Input 15 in place of x:

y = 3(15) - 5

Solve:

y = 45 -5

y = 40

When x is 15, y is 40.

Hope this helps :)

What is the y-intercept of the line that passes through the points (2, -1) and
(-3, 9)?

Answers

Answer:

the y intercept is (0, 3)

Step-by-step explanation:

y = mx + c

where m is the slope and c is the y-intercept

[tex]m = \frac{y_2 - y_1}{x_2 - x_1 }[/tex]

[tex]m = \frac{9 - -1}{-3 - 2 }[/tex]

[tex]m = \frac{10}{-5}[/tex]

[tex]m = -2[/tex]

hence, y = -2x + c

input a pair of values, in this case i will use (2, -1)

-1 = -2(2) + c

-1 = -4 + c

-1 + 4 = c

3 = c

What is a function?

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

here, we have,

The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.

It is a straight line because the degree of the variable or its maximum power is one.

Put x = 0

y = 10 + 0 = 10, therefore one point (0,10)

Put y = 0

0 = 10 +x

Another point since x = -10. (-10,0)

As shown in the graph below, a straight line should be drawn through both locations.

Any point on the line that does not satisfy the equation is a nonexistent point.

Hence the function  y=10+×. is plotted below.

Answers

X= 25 because you set both equations equal to each other so 6x - 2 = 4x + 48 then to find the measure of the angle you plug in the value of X. So angle A = 6(25) -2 = 148

Answer:

x = 25 ; m∠A = 148°

Step-by-step explanation:

∠A ≅ ∠B (alternate exterior angles)

(6x - 2)° = (4x + 48)°

2x = 50

x = 25

m∠A = 6(25) - 2 = 148°

Answer:In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount be A = 10 kg

Now , the percentage decrease in value = 10 %

So , the equation will be

The amount after decrease =
Total amount - ( percentage decrease in value x total amount )

And , the equation is

The amount after decrease = 10 - ( 10/100 ) x 10

                                              = 10 - 0.1 x 10

                                              = 10 - 1

The amount after decrease = 9 kg

Therefore , the value is 9 kg after decrease in 10 %

Hence , The value after the decrease in 10% is 9 kg

to find a discount you would multiply 50(0.20) whatever amount you get you would subtract that from 50

this is the same as 50(0.80)

The triangles are not similar because the sides are not proportional.

What are Similar Triangles?

Similar triangles are those triangles which has the same shape but different size.

The length of sides and angles are proportional in similar triangles.

So we know that length of sides are proportional.

If we find the ratio of corresponding sides of the two triangles, then they must be equal to a common value.

We have only the length of two sides of each triangle.

If those sides are proportional, we must have an angle of each triangle to be equal.

Here, the angles formed by the intersecting lines are vertical angles and are thus equal.

Let's look if the sides are proportional.

20 / 36 = 5/9

24 / 42 = 4/7

Sides are not proportional.

We are planning a reception for our daughter. The hall that we are renting charges a $90 cleanup fee. In addition to the cleanup fee, they charge $29 per guest for food and drinks.
If we have $3,100.00 available, what is the maximum number of guest we can invite without going over our budget?

Answers

Answer:

The equation is y = 29x + 90. So, if you plug in 3,100.00 for y.

3,100.00 = 29x + 90

3,100.00 - 90 = 29x

3,010.00 = 29x

3,010.00/29 = 29x/29

Laura's ingredient was used the least. More of Paige's ingredient was used than Jacob's. Who brought the ginger?

5/8 of pumpkin was left so 3/8 was used.

Corey's was used the most, 3/4 is the largest used, so Corey had the cinnamon.

Laura's was used least, 3/8 is the smallest amount so Laura had the pumpkin.

2/3 is more then 1/2, so there was more ginger used than nutmeg.

More of Paige's was used, so Paige had the ginger.
