Answers For The 2 Boxes

Answers

Answer 1

Step-by-step explanation:

y = 4x + 3.

Therefore y = 7 + 3x

=> (4x + 3) = 7 + 3x

=> x = 4.

y = 4(4) + 3 = 19.

The solution pair is (4,19).

Drag a point to the numb

Answers

Step-by-step explanation:

The given inequality is :

[tex]350\ge 125+15x[/tex] ....(1)

We need to draw graph of this inequality.

Subtract 125 from both sides.

[tex]350-125\ge 125-125+15x\\\\225\ge 15x[/tex]

Dividing 15 to both sides.

[tex]\dfrac{225}{15}\ge \dfrac{15x}{15}\\\\15\ge x[/tex]

Hence, the attached figure shows the graph for this inequality.

how do you differentiate more and more than? can these terms be used in mathematics? how?​

Answers

Answer:

The terms "more" and "more than" have a clear difference, which is even more noticeable in its application in the field of mathematics.

Thus, "more" has a more general meaning, while "more than" applies specifically to comparing the values of two or more determined variables. Therefore, in the field of mathematics "more than" implies that a variable will have a higher value than another or others, while "more" simply refers to a higher value.

Mean:

Range:

Answers

Answer:

mean- 66

median- 7

mode- 8

range- 6

Step-by-step explanation:

to find the mode you line up all the numbers, add them all together and then divide that number by 2.

to find the median you line up all the numbers then one by one taking turns from left to right you cross of the numbers to find the number in the middle. (think of median as middle)

to find mode you just find the number that is used the most. (mode=most)

to find the range you find the highest number and the lowest number. and subtract the lowest from the highest to find the difference between the 2. in this case its 9-3 so the difference is 6.

Triangles triangle ABC and triangle DEF are similar. Find the angles of these triangles if Mesurements of angle A=100 degrees, and mesurments of angle B=30 degrees.

Answers

Answer:

<D = 100

<E =30

<F =50

Step-by-step explanation

Given that triangles triangle ABC and triangle DEF are similar, this means that their angles are congruent i.e

<A = <D

<B = <E

<C = <F

Given

<A = 100 then <D = 100

<B = 30°, then <E = 30°

To get <F, we will use the expression

<D+<E+<F = 180 (sum of angles in a triangle is 180°)

100+30+<F = 180

130+<F = 180

<F = 180-130

<F = 50°

Hence the measure of <F is 50°

f(1)=2

f(n+1) = f(n)+4


What is f(10)?

Answers

9514 1404 393

Answer:

  38

Step-by-step explanation:

The recursion relation describes an arithmetic sequence with a first term of 2 and a common difference of 4. The explicit formula for the n-th term of the sequence is ...

  f(n) = f(1) +d(n -1) . . . . . for first term f(1) and difference d

  f(n) = 2 +4(n -1) = 4n -2

Then the 10th term is ...

  f(10) = 4(10) -2

  f(10) = 38

determine the values of X for which g(x) is defined​

Answers

Answer: Any real number x as long as [tex]x \ne 0[/tex] and [tex]x \ne -\frac{2}{3}[/tex]

In other words, anything but 0 or -2/3 is valid.

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

Explanation:

Set the denominator equal to zero and solve for x

2(3x^2 + 2x) = 0

3x^2 + 2x = 0

x(3x + 2) = 0

x = 0 or 3x+2 = 0 .... zero product property

x = 0 or 3x = -2

x = 0 or x = -2/3

If either x = 0 or x = -2/3, then the denominator 2(3x^2 + 2x)  will be zero. But recall that we cannot have zero in the denominator. Dividing by zero is not allowed. The expression is undefined when we divide by zero.

Therefore, we must exclude x = 0 and x = -2/3 from the domain. Any other real number is valid as an x input.

i think you multiply it by 4 on both sides

Answer:

A. Right a multiple of 2 and up a multiple of 1.

B. (2, 1)

C. the same

Step-by-step explanation:

A. The original point was (2, 1), so if Larissa moves right a multiple of 2 and up a multiple of 1, she'll stay within the ratio.

B. We already know this is proportional, since it goes through the origin; the line just has to pass through the right point: (2,1)

C. The line will be proportional, so as long x is twice as much as y, Larissa will have the same shade of green paint every time.

PLSSSSSS HELP I WILL MARK BRAINLIESTAfter Democratic triumph in the state elections of 1870 and aggressive federal intervention in 1871 and 1872, the formal Klan organization began to fade away. Local Klan-like groups continued to engage in racial and political terrorism, often calling themselves minutemen or rifle clubs, but they lacked larger organizational ties or even commonality of purpose. A romanticized memory of the first KKK legitimated their activities and, combined with the growing power of a Lost Cause mythology, contributed greatly to Georgians' acceptance of vigilante violence and lynching well into the twentieth century. By the 1890s, many men proudly claimed to have ridden with the Klan and thereby saved Georgia and the South from "Negro domination." This romanticized vision of the Klan was celebrated in popular novels and laid the foundation for the more openly organized Knights of the Ku Klux Klan, the second Ku Klux Klan, founded in Atlanta in 1915.Ku Klux Klan in the Reconstruction Era,Jonathan M.
