PLEASE HELP What is the slope of the line y=−4y

Answer:

x=(5/2,-3)

Step-by-step explanation:

2x²+x=15

2x²+x-15=0

(2x-5)(x+3)=0

x=(5/2,-3)

Answer:

Step-by-step explanation:

AB + BC = AC

9x + 7  - 3x + 20 = 39    { combine like terms}

9x  -3x + 7 + 20 = 39

            6x + 27 = 39 {Subtract 27 from both sides}

                     6x = 39- 27

                      6x = 12   {divide both sides by 6}

                    6x/6 = 12/6

x = 2

Since you can earn 28 dollars by washing 7 cars, and you want to find the amount money you can make by washing 6 cars.

[tex]\frac{28}{7} = \frac{x}{6}[/tex]

First, you should find the amount of money you can make by washing 1 car (unit rate).

[tex]\frac{28}{7} = \frac{x}{1}[/tex]

To get from 7 to 1, you have to divide 7 by 7; 7 ÷ 7 = 1.

Do the same thing to the numerator; 28 ÷ 7 = 4.

Now you know how much you make by washing 1 car, you need to find how much you make by washing 6 cars.

[tex]\frac{4}{1} = \frac{x}{6}[/tex]

To get from 1 to 6, you multiply by 6. 1 times 6 equals 6.

Now do the same thing to the numerator; 4 × 6 = 24.

You can earn 24 dollars by washing 6 cars.

Answer:

C = 75 + 25m

Step-by-step explanation:

The one time fee is 75 and membership dues are 25 per month.

This corresponds to C = 75 + 25m because the one time fee is 75 and each month you pay 25.

Answer and explanation:

We know that this is in slope-intercept form. ( y = mx + b )

1/2 would be the slope (you would use this to graph the next point)

-4 would by your y-intercept (where the line crosses the x-axis)

With this information you could graph any point using the slope given, starting at -4 (x-axis) going down or up.

Divide each side by (4c+5)

x = 1/ ( 4c+5)

Answer:

26

Step-by-step explanation:

here,

the lower angle when sumed,

it is like: 154+a=180 (let angle be a) being supplementary angle sum is 180

so value of a becomes 26

then,

the above angle x is corresponding to angle a (a=x)

So value x is 26

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{13 \: \: units \: }}}}}[/tex]

Step-by-step explanation:

Perpendicular ( p ) = 5

Base ( b ) = 12

Hypotenuse ( h ) = ?

Finding the length of missing side

Using Pythagoras theorem

[tex] \boxed{ \sf{ {h}^{2} = { p}^{2} + {b}^{2} }}[/tex]

plug the values

⇒[tex] \sf{ {h}^{2} = {5}^{2} + {12}^{2} }[/tex]

Evaluate the power

⇒[tex] \sf{ {h}^{2} = 25 + 144}[/tex]

Add the numbers : 25 and 144

⇒[tex] \sf{ {h}^{2} = 169}[/tex]

Squaring on both sides

⇒[tex] \sf{ \sqrt{ {h}^{2} } = \sqrt{169}} [/tex]

Calculate

⇒[tex] \sf{ {h} = 13 \: units}[/tex]

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S.

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15.

Answer/Step-by-step explanation:

The following inequalities can be translated and matched as follows:

1. A number is larger than 5:

Let that number be x. Numbers that are larger than 5 are 6, 7, 8 and so on. Therefore, the number that is larger is greater than 5. This can be represented in the symbolic form as:

x > 5

2. A number is below 5:

Numbers that are below 5 are 4, 3, 2 and so on. Therefore, we can say the number, x, is less than 5. This can be written in symbolic form as:

x < 5

3. A number is not less than 5:

A number that is not less than 5 could equal 5 or any other number that is larger than 5. Therefore, we can say the number, x, equals 5 or greater than 5. This can be written as:

x ≥ 5

4. A number is at most 5:

At most 5, means the number, x, is either 5 or less than 5. This can be written as:

x ≤ 5

Answer:

The manager's prediction is false

Step-by-step explanation:

Given

Jacob: 2000x + 4000

Carlos: 3500x - 40000

Required

Determine if both expression will be the same if x = 35

To do this;

Equate both expressions and then solve for x

i.e.

[tex]2000x + 4000 = 3500x - 40000[/tex]

Collect Like Terms

[tex]2000x - 3500x = -4000 - 40000[/tex]

[tex]-1500x = -44000[/tex]

Divide both sides by -1500

[tex]\frac{-1500x}{-1500} = \frac{-44000}{-1500}[/tex]

[tex]x = \frac{-44000}{-1500}[/tex]

[tex]x - 29.3[/tex]

Hence, the manager's prediction is not true because [tex]x \neq 35[/tex]

Answer:

Linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.

Step-by-step explanation:

If we have two linear functions f(x) and g(x) which are intersecting at a point (a,b), then equating both functions we get a linear equation as

[tex]f(x)=g(x)=y[/tex]

On solving this linear equation we get the x-coordinate of the point of intersection, i.e., x=a.

After that, we need to substitute x=a in either f(x) or g(x) to get the y-coordinate of the point of intersection.

Therefore, the linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.

Answer: dark blue

8 for a cd and start with $15

Step-by-step explanation: Here, notice that the value that we

don't know is how many CDs are purchased.

Since CD's cost $8, we multiply 8 by our variable, which is x.

So we have 8 times x or 8x.

In addition, since there is a one time fee

of $15 to begin, we add 15 to 8x.

So we have 8x + 15.

Answer:

215 sections of 27 meters of rope will be created and 9 meters will be left as waste

Step-by-step explanation:

A rope that is 5814 meters long needs to be cut into 27 sections

The number of 27 meter sections of rope that can be created can be calculated by dividing 5814 by 27

= 5814/27

= 215 remainder 9

Hence 215 sections of rope will be created and 9 meters of rope will be left as waste

Answer:

Step-by-step explanation:

Given the inequality  |q+8|≥2, we are to solve for q. Note that the function inside modulus sign will return both negative and positive value.

For the positive function:

q+8≥2

Subtract 8 from both sides of the inequality.

q+8-8≥2-8

q ≥ -6

For the negative function;

-(q+8)≥2

open the parenthesis

-q-8≥2

add 8 to both sides

-q-8+8≥2+8

-q≥10

Multiply both sides by -1. Note that multiplying both sides of an inequality changes the direction of the inequality sign.

q≤-10

Combining both results i.e q ≥ -6 and q≤-10

q ≥ -6 can also be written as -6≤q

Combining -6≤q with q≤-10, this will give -6≤q≤-10.

Hence the result of the inequality function given is  -6≤q≤-10.

Answer:

D

Step-by-step explanation:

A polynomial in standard form has the terms in ascending order.

In other words, the term with the largest degree is on the left, followed by the term with the second largest degree, etc.

The largest term in this polynomial is 2x³. Thus, we need to start with that.

The only choice that starts with 2x³ is choice D.

Thus, choice D is in standard form.

And examining choice D, we see that it is in ascending order all the way through.

you need to find like denominators

[tex]\frac{9}{12} -\frac{8}{12 }[/tex]

Now subtract

[tex]\frac{1}{12}[/tex]

Answer:

No

Step-by-step explanation:

So lets do the first expression first

2(3x-6)

6x-6

So the first one is 6x-6

Now the second expression

2(3x)x-6

As you can see here, there's an extra x in this problem compared to the last problem, but lets still work it out

6x*x-6

So they are different.

If the extra x wasn't there then it would've worked.
