x^2+3x+37=-7x
I'm supposed to complete the square but my teacher did not explain it well at all. It would be really great if you showed the steps to get the answer :)

Answers

Answer 1

Answer:

x= -74 or -84

Step-by-step explanation:

x^2+3x+37=-7x

x^2+3x+7x+37=0

x^2+10x+37=0

this convert to following

[tex]( - b + - \sqrt{ {b}^{2} } - 4 \times a \times c) \div 2 \times a[/tex]

-b= -(10), a= 1, c =37

according to that

x= -74 or x= -84

Write the equation for the line with the given points (0,-3) and (2,9) in point slope form

Answers

Equation: Y = mx + b
First of all, we will solve for our M which is our slope.
M = Yb - Ya / Xb - Xa
M = 9 - (-3) / 2 - 0
M = 9 + 3 / 2 - 0
M = 12 / 2
M = 6

Now that we have our slope, we will be finding our y-intercept.
Y = mx + b
9 = (6)(2) + b
9 = 12 + b
= 9-12 = 12-12 + b (12 cancels out)
= -3 = b

So, therefore, the equation is: Y = 6x - 3

Jacy paid $15.48 to download 12 songs last month. She paid the same amount for each song and also had to spend $5.04 to enroll in the music purchasing program.

Part A
Let s represent the amount that Jacy paid for each song she downloaded.
Which equation could you use to find the value of s?
12s = 15.48
15.48 + s = 12 + 5.04
12 + s = 15.48 + 5.04
12s + 5.04 = 15.48

Answers

12s = $15.48

Hope this helps!
Have a nice day :)

The solution is, 12s + 5.04 = 15.48, is the equation which could you use to find the value of s.

What is equation?

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

given that,

Jacy paid $15.48 to download 12 songs last month.

She paid the same amount for each song and also had to spend $5.04 to enroll in the music purchasing program.

now, we have,

Let s represent the amount that Jacy paid for each song she downloaded.

so, we get,

She paid the same amount for each song and also had to spend $5.04 to enroll in the music purchasing program.

i.e. 12s + 5.04

and, Jacy paid $15.48

i.e. the equation which could you use to find the value of s is,

12s + 5.04 = 15.48

Hence, The solution is, 12s + 5.04 = 15.48, is the equation which could you use to find the value of s.

Divide £320 in the ratio 3:5

Answers

Answer:

£120 : £200

Step-by-step explanation:

sum the parts of the ratio, 3 + 5 = 8 parts

Divide the amount by 8 to find the value of one part

£320 ÷ 8 = £40 , then

3 parts = 3 × £40 = £120

5 parts = 5 × £40 = £200

Then £320 in the ratio 3 : 5 is £120 : £200

The division of  £320 in the ratio of 3: 5 is £120: £200.

What is the arithmetic operator?

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given the amount of £320

Now,

The ratio is 3: 5 so divide 320 by 3 + 5 to find the per unit ratio value.

So,

320/8 = 40

Now,

Multiply by 3 ⇒ 3 × 40 = 120

Multiply by 5 ⇒ 5 × 40 = 200

So ratio 120/200 = £120: £200.

Hence "The division of  £320 in the ratio of 3: 5 is £120: £200".

Point M is on line segment LN. Given MN = 3x, LN = 4x + 9, and
LM 2x + 7, determine the numerical length of LM.

Answers

Answer:

LM = 11 units

Step-by-step explanation:

Given M  is on LN , then

LM + MN = LN , substitute values

2x + 7 + 3x = 4x + 9

5x + 7 = 4x + 9 ( subtract 4x from both sides )

x + 7 = 9 ( subtract 7 from both sides )

x = 2

Thus

LM = 2x + 7 = 2(2) + 7 = 4 + 7 = 11

Solve the area formula for a circle, A = πr2, for r2.

Step-by-step explanation:

To solve an equation for one of its variables, do that

Separate the term of this variable on one side and the other terms on the other sidesMake the coefficient of the variable equals1 (if it is not 1)

Let us solve the question

∵ The formula of the area of the circle is A = π r²

∵ The subject is r² ⇒ The variable which we need to solve for it

→ By using the 1st step up divide both sides by π to move it from the right

   side to the left side

∵ [tex]\frac{A}{\pi }[/tex] = [tex]\frac{\pi r^{2}}{\pi }[/tex]

∴ [tex]\frac{A}{\pi }[/tex] = r²

→ Switch the two sides

r² = [tex]\frac{A}{\pi }[/tex]

The rational number lies between −67/7 and−78/8


Pls explain and pls don't write bad answer pls

Answers

9514 1404 393

Answer:

   -135/14

Step-by-step explanation:

There are an infinite number of rational numbers between any pair of numbers you name. These two number have the decimal values ...

  -67/7 = -9 4/7 = -9.571428... (repeating)

  -78/8 = -9 3/4 = -9.75

So, numbers like -9.6 = -48/5, or -9.7 = -97/10 are rational numbers that lie in the range you specified.

If you like, you can convert these numbers to ones with a common denominator (56).

 -67/7 = -536/56

 -78/8 = -546/56

These limits suggest several possible rational numbers with 56 as a denominator: -540/56 = -135/14, for example.

Write the equation of the line that passes through the point (1,4) and is parallel to y=5

Answers

Answer:

The equation of the desired line is thus y = 4

Step-by-step explanation:

A line parallel to y = 5 is a horizontal line.  The x-coordinate of every point on this line can take on any x-value; the y-coordinate is always 5.

The line that passes through the point (1, 4) has the constant y-coordinate 4, whereas x can take on any value.

The equation of the desired line is thus y = 4; this line passes through (1, 4) as required and is parallel to y = 5.

Is x=|y| with inputs x=1, x=2, and x=3 a function? Explain

Answers

Answer: This is not a function

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

Explanation:

If x = 1, then,

x = |y|

1 = |y|

|y| = 1

y = plus/minus 1

y = 1 or y = -1

The input x = 1 leads to more than one output y = 1 and y = -1 at the same time.

Similar situations occur with x = 2 and x = 3.

This means we do not have a function. A function can only be possible if each input leads to exactly one output.
