x+2y=6 how do I solve this ?​

Answers

Answer 1

Answer:

The answer is 4y

Step-by-step explanation:

This is because when you have a variable and 2 numbers you work backwards to find the number of the x so you do the opposite of adding you subtract,  2 - 6 remember you are working backwards but now you have the answer 4 but there is a variable next to the two so you so you add that to the four.

Please solve this quick 8n+7=31

Answers

Hello there!

To find the value of n, work to isolate it from all other terms in the equation.

8n+7=31 - Start by subtracting 7 from both sides. 8n + 7 - 7 = 31 - 7

8n = 24 Next, divide both sides by 8 to finish isolating n. 8n÷8 = 24÷8

n = 3

This is your final answer.

I hope this was helpful and have a great rest of your day!

:)

For this case we must solve the following equation of first degree:

[tex]8n + 7 = 31[/tex]

We subtract "7" on both sides of the equation:

[tex]8n + 7-7 = 31-7\\8n = 24[/tex]

We divide between "8" on both sides of the equation:

[tex]\frac {8n} {8} = \frac {24} {8}\\n = 3[/tex]

Thus, the value of the variable n is 3.

[tex]n = 3[/tex]

If the ramp will be 3 feet above the ground and have a 4 foot Base , How long will the ramp be?

Answers

Answer:

5 feet long

Step-by-step explanation:

According to the Pythagorean Theorem, a^2 + b^2 = c^2  where "a" and "b" are the two legs of the right triangle and "c" is the hypotenuse.

We are trying to find the part that is at an angle, which is "c". So if we know "a" is "3 and "b" is 4, we can plug the values into the equation.

3^2 + 4^2 = c^2       plug in the values

9  +  16 = c^2           simply the two squared values

25 = c^2                   add the two values

5 = c                          take the square root of both sides

c = 5                          switch the values

ANSWER

[tex] \sqrt{65} [/tex]

EXPLANATION

We were given the points,

(-5,1) and (3,0).

We use the distance formula to obtain;

[tex]d = \sqrt{ {(x_2-x_1)}^{2} + {(y_2-y_1)}^{2} } [/tex]

Let [tex](x_1,y_1)=(-5,1)[/tex]

and [tex](x_2,y_2)=(3,0)[/tex]


We substitute these values to get,

[tex]d = \sqrt{ {(3 - - 5)}^{2} + {(0 - 1)}^{2} } [/tex]

identify a transformation of the function f(x) = √x by observing the equation of the function g(x) = √x-2

Answers

Answer:

[tex]f(x)=\sqrt{x}[/tex] is the Square Root Function. These are the characteristics of the graph of the square root function:

The domain of the function is the set of all non negative real numbers. The range of the function is the set of all non negative real numbers. The graph has an intercept at [tex](0,0)[/tex]. The graph is increasing on the interval [tex](0, \infty)[/tex].

Since the function [tex]g(x)=\sqrt{x}-2[/tex], then this stands for the form:

[tex]g(x)=f(x)-c[/tex]. This form tells us that the graph of f has been shifted c units downward where the value c = 2 in this problem. The graphs of both functions are shown below. The red one is [tex]f(x)[/tex] while the blue one is [tex]g(x)[/tex]

Answer:

The transfomation made is a vertical translation 2 units downwards.

Step-by-step explanation:

The parent function is

[tex]f(x)=\sqrt{x}[/tex]

Remember that a parent function is the simplest function of its type, like this case the function [tex]f(x)[/tex] is the simplest form of radical functions.

The transformed function is

[tex]g(x)=\sqrt{x}-2[/tex]

Notice that the difference between these two functions is that [tex]g(x)[/tex] has 2 units less on the vertical or dependent variable, such transformation indicates a vertical translation downwards.

Therefore, the transfomation made is a vertical translation 2 units downwards.

C) A resident in the group who supports the tax is likely to be male

Answer:

The correct choice is:

 A resident in the group who supports the tax is likely to be male.

Step-by-step explanation:

The table is given by:

                   Support              Against           Total

Female            20%                    74%              54%

Male                 80%                    27%              44%

Total                 100%                  100%             100%

Based on the table we observe that the of the people who supported the tax most of them are males.

Since the percent of males who supported tax are 80% which is more than the females who supported tax i.e. 20%.

Hence, the answer is: last option.

Which exponential function goes through the points (1, 8) and (4, 64)? f(x) = 4(2)x f(x) = 2(4)x f(x) = 4(2)−x f(x) = 2(4)−x

Answers

Answer:

y = 4(2^x)

Step-by-step explanation:

To write the exponential values, compare the y values. Notice they are multiples of 8 and they are increasing. This means the base is likely 2 or 4 since each of these numbers has the same multiples. Our options also only include base 2 and 4.

Try 4^1 = 4 and 4^4 = 256.

Try 2^1 = 2 and 2^4 = 16.

None of these give the exact values in the points. This means there is an initial value multiplied to them as well.

When x = 1 and the base is 4, the value is too small. But when x = 4, the value is too large. This cannot be reconciled.

When x = 1 and x = 4 for the base 2, both values are too small and could be multiplied by the same number to get the right values.

2*4 = 8

16*4 = 64

The initial value is 4 so the function is [tex]y = 4(2^x)[/tex]

Brooke paints the outsides of the square walls and triangular ceilings of her treehouse. What area does she paint?​

Answers

Answer:

Broke paints [tex]216\ ft^{2}[/tex]

Step-by-step explanation:

we know that

The area of the outsides of the square walls and triangular ceilings of her tree house is equal to the area of four squares and four triangles

so

[tex]A=4[(6)^{2} +\frac{1}{2}(6)(6)]\\ \\A=4[36+18]\\ \\A=216\ ft^{2}[/tex]

The surface area of the square walls and triangular ceiling she painted is 216 ft²

How to find the surface area of the painted region?

The surface area of the painted region can be found as follows:

area of the square = l²

where

l = side length

Therefore,

l = 6 ft

area of the square = 6² = 36 ft²

Area of the triangular region = 1 / 2 bh

where

b = baseh = height

Therefore,

area of the triangular region = 1 /  2 × 6 × 6 = 36 / 2  = 18 ft²

Therefore,

area of the painted region = 18(4) + 36(4) = 144 + 72 = 216 ft²

find the volume of 2 , 10 1/5 , and 4 1/4

Answers

Answer:

86.7

Step-by-step explanation:

2 x 10.2 x 4.25 = 86.7

To find the volume you need to multiply all these 3 values.

After multiplying it all that amount will be the answer.

The volume of the given dimensions is [tex]\(86.7\)[/tex] cubic units.

To find the volume, we multiply the three given dimensions together. The dimensions given are [tex]\(2\)[/tex], [tex]\(10 \frac{1}{5}\)[/tex], and [tex]\(4 \frac{1}{4}\)[/tex].

First, we need to convert the mixed numbers to improper fractions:

1. Convert [tex]\(10 \frac{1}{5}\)[/tex] to an improper fraction:

[tex]\[ 10 \frac{1}{5} = 10 + \frac{1}{5} = \frac{50}{5} + \frac{1}{5} = \frac{51}{5} \][/tex]

2. Convert [tex]\(4 \frac{1}{4}\)[/tex] to an improper fraction:

[tex]\[ 4 \frac{1}{4} = 4 + \frac{1}{4} = \frac{16}{4} + \frac{1}{4} = \frac{17}{4} \][/tex]

Next, multiply the three dimensions together.

First, convert the whole number [tex]\(2\)[/tex] to a fraction:

[tex]\[ 2 = \frac{2}{1} \][/tex]

Now, multiply the fractions:

[tex]\[ \frac{2}{1} \times \frac{51}{5} \times \frac{17}{4} \][/tex]

[tex]\[ \frac{2 \times 51}{1 \times 5} = \frac{102}{5} \][/tex]

[tex]\[ \frac{102 \times 17}{5 \times 4} = \frac{1734}{20} \][/tex]

[tex]\[ \frac{1734}{20} = 86.7 \][/tex]

Loren and Julie have different part-time jobs after school. They are both paid at a constant rate of dollars per hour. The tables bellow show Loren and Julie’s total income for work given amount of time.

How much money would Julie earn for working 16 hours?

Julie works 1/12 hours/dollars. Write one or two-sentence explanation of what this rate means use this rate to find how long it takes for Julie to earn $228

Answers

Julie would earn $12/h×16h=$192

This rate means that for each hour she works, she gets $12.

The general formula for calculating these types of problems is:

m = r × t,

where m marks the total amount of money, r marks the rate and t marks the time.

To find the time when

m = $228

r = $12/h,

t = m ÷ t = 228 ÷ 12 = 19 hours.

Julie's income for 16 hours is $192. Julie takes only 24 hours to earn $288. The rate is $12 for each hour.

What are ratio and proportion?

A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

Loren and Julie have different part-time jobs after school.

They are both paid at a constant rate of dollars per hour.

The income of Julie is $36 in 3 hours.

For 1 hour, Julie earns $12.

Thus the rate of Julie is $12 per hour.

For the 16 hours, Julie's income will be.

Julie's income for 16 hours = 12 x 16

Julie's income for 16 hours = $192

Julie's income for 16 hours is $192.

Julie takes time to earn $228 will be

[tex]\rm Time = \dfrac{288}{12}\\\\Time = 24[/tex]

Thus, Julie takes only 24 hours to earn $288.

A jewelry store is having a going-out-of-business sale. All merchandise is marked 40% off the regular price. The regular price of a watch is $59.95 what is the amount of the discount and the sale price

Answers

Answer:

$35.97

Step-by-step explanation:

the regular price is 59.95

40% discount so

let's say the price now is x and i am gonna do fractions

x/59.95 = 40%/100

100 x X = 100x  

59.95 x 40 = 2398

i divide 2398 by 100 which equal 23.98

40% is 23.98 and then i do 59.95 - 23.96 = 35.97

DONE!

The discount amount on the watch is $23.98 and the sale price after applying the 40% discount off the regular price of $59.95 is $35.97.

When a jewelry store is having a going-out-of-business sale, and all merchandise is marked 40% off the regular price, we can calculate the amount of the discount and the sale price using percentage formulas. For example, if a watch has a regular price of $59.95, we multiply this price by 40% (or 0.40) to find the discount amount.
To find the discount amount: $59.95 times 0.40 = $23.98

Next, to find the sale price, we subtract the discount amount from the regular price.
To find the sale price: $59.95 - $23.98 = $35.97

Therefore, the discount amount is $23.98, and the sale price of the watch is $35.97.
