Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

2x+4 = (x²)²÷2

2x + 4 = x^4/2

x^4 = 4x + 8

x^4 - 4x - 8 = 0

We can try trial an error to solve this

Looks like x = 2 fits it:

2^4 - 4(2) - 8

= 16 -8 -8 = 0

so x = 2 is one solution.

I can't find any other solution among other integers.

To find the other solutions you can draw a graph manually or by using software.

There will be either 1 or 3 more real solutions.

I used software to draw the graph and found one other solution:

x = -1.296

Hey there!

I think that some of the content in your question is missing so I will be solving for how much yards of fabric is needed in total

Since all of the fractions have common denominators, we can comfortably add them together

3/4+3/4+2/4 is 8/4

8/4 can be simplied to 2

So the total amount of yards of fabric Thom needs in total is 2 yards

Answer:

[tex]area \: of \: triangle \: = \frac{1}{2} b \times h[/tex]

The area of a triangle formula is A = 1/2 × b × h, where b is base and h is height.

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

Here,

The area of a triangle formula is 1/2× b × h, where b=base and h=height.

Example: Find the area of a triangle with base 12 units and height 3 units.

Now, area of a triangle = 1/2× 12 × 3

= 6 × 3

= 18 square units

Therefore, area of a triangle formula is A = 1/2 × b × h.

Answer:

C)  (-1, -4) and (4, 6)

Step-by-step explanation:

[tex]\textsf{Equation 1}:y=2x-2[/tex]

[tex]\textsf{Equation 2}:y=x^2-x-6[/tex]

Substitute Equation 1 into Equation 2 and solve for x:

[tex]\implies 2x-2=x^2-x-6[/tex]

[tex]\implies x^2-3x-4=0[/tex]

Find two numbers that multiply to -4 and sum to -3:  -4 and 1

Rewrite the middle term as the sum of these two numbers:

[tex]\implies x^2-4x+x-4=0[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies x(x-4)+1(x-4)=0[/tex]

Factor out the common term [tex](x-4)[/tex]:

[tex]\implies (x+1)(x-4)=0[/tex]

[tex]\implies (x+1)=0 \implies x=-1[/tex]

[tex]\implies (x-4)=0 \implies x=4[/tex]

Substitute the found values of x into Equation 1 and solve for y:

[tex]x=-1 \implies y=2(-1)-2=-4[/tex]

[tex]x=4 \implies y=2(4)-2=6[/tex]

Therefore, the solution to the system of equations is:

[tex]c-10c+3c=4c-10c=-6c[/tex]

Step-by-step explanation:

The expression which is equal to the given expression c - 10c + 3c will be -6c.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

As per the given expression,

c - 10c + 3c = c + 3c - 10c

                   = 4c - 10c

                   = -6c

Hence "The expression which is equal to the given expression c - 10c + 3c will be -6c".

The point of intersection is (3,1)

Step-by-step explanation:

Manipulate these equations to achieve the form of y = mx + c

1) y + 5 = 2x

Y = 2x - 5

2) y = 7 - 2x

Y = -2x + 7

Point of intersection is (3,1) on the graph attached

To check algebraically:

2x - 5 = -2x + 7

4x = 12

X = 3

Substitute to get y

Y = 2x - 5

Y = 2 x 3 - 5

Y = 1

Therefore (3,1)

Answer:

B. The interquartile range is 55

Step-by-step explanation:

the interquartile range is Q3 minus Q1, you would get 15 ,not 55. So B is the answer to your question

Answer:

B. The interquartile range is 55.

Step-by-step explanation:

In this problem, I refer to the right part of the box as the median of the upper half and the left part of the box as the median of the lower half.

The median of the data is going to be the middle line of the box and whisker plot. The middle line lies on 55, so the median is 55.

Choice A is true

The interquartile range is the right end of the box subtracted from the left end of the box. The right end of the box is 65. The left end of the box is 40. Subtracting the left end from the right end, we get 25.

Choice B is false

3/4 of the data will be where we see the right end of the box. The right end of the box is at 65. So, 3/4 of the data is less than 65.

Note: 1/4 of the data is less than the left side of the box at 40. 1/2 of the data is less than the median of the box which is at 55.

Choice C is true

The median of the upper half is the right end which is 65.

Note: The median of the lower half is 40.

Choice D is true

Answer:

Step-by-step explanation:

Formula

SA = 2*pi r^2 + 2*pi * r * h

Givens

pi = 3.14

r = d/2                   radius = diameter /2

r = 7/2 = 3.5

h = 10 cm

Solution

SA = 2*3.14 *3.5^2 + 2*3.14 * 3.5 * 10

SA = 76.93 + 219.8

SA = 296.73 cm^2

Answer:

57.6% have allergies

42.4% have no allergies

Step-by-step explanation:

We only need to consider the students who speak two languages according to the question.

To find the percent with allergies, divide the number of students with allergies by the total number of students (that speak two languages).

19/33 = 0.5757 = 57.6%

To find the percent without allergies, divide the number of students without allergies by the total number of students (that speak two languages).

14/33 = 0.4242 = 42.4%

Check your work by adding the percentages to make sure they equal 100%

57.6 + 42.4 = 100

Answer:

2,000 square feet

Explanation:

If the kitchen is 300 square feet, we can divide that by the percentage(15%). We get the answer 20, which will be our conversion factor!

Now, we multiply this conversion factor by all the other percentages(without decimals)

5 x 20 = 100

20 x 20 = 400

30 x 20 = 600

15 x 20 = 300

30 x 20 = 600

Now we add up all of these factors and get the answer :D

100 + 400 + 600 + 300 + 600 = 2,000 square feet

Solution:

Ria's salary before tax is £3,000 per month.

(i.e) £12 * 3,000/year =  £36,000.
