Answer:

x < 0  , y > 0

Step-by-step explanation:

In quadrant II, the x variable is less than 0 and the y variable is greater than 0

x < 0  , y > 0

Answer:

x < 0 and y > 0

Step-by-step explanation:

Quadrant II is the upper left quadrant.

In that quadrant, all x values are negative since it's to the left of the y-axis.

In that quadrant, all y values are positive since it's above the x-axis.

Answer: x < 0 and y > 0

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:

The kinetic energy of the car is 0.466 J

Correct Answer: A. 0.466 J Explanation: If there is no friction, all of the gravitational potential energy of the car at the top of the hill will be converted to kinetic energy at the bottom of the hill. The potential energy of the car is equal to the product of its mass, height, and gravitational acceleration.0.05 kg • 0.95 m • 9.81 m/s2 = 0.466 J.

Answer:

Composite

Step-by-step explanation:

A whole number that can be divided exactly by numbers other than 1 or itself. Example: 9 can be divided exactly by 3 (as well as 1 and 9), so 9 is a composite number

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:

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.

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.

Answer: The answer is 39

Step-by-step explanation: You get this answer by following the PEMDAS stragey. You multiply 17 and 2 to get 34. Next, you add 21 adn 34 to get 55. Next, you subtract 15 from 55 to get 40. Finally,  you subtract 1 from 40 and get 39.

Answer: D

Step-by-step explanation:

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

Step-by-step explanation:

The domain is the input values

A has an input of 2

B has an input of all real values

D has an input of 1,0,2,6

C has an input of -4,-2,2,4

Answer:

  any value other than 8

Step-by-step explanation:

If c = 8, the two sides of the equation say the same thing, so any value of x will satisfy the equation.

If c ≠ 8, there are no values of x that can make the equation true, hence no solutions.

There is no solution for any value of c that is not 8.

[tex]c=-3x+8+3x\\c=8[/tex]

If c = 8 then the solution is infinite. (because the equation is true)

[tex]-3x+7=-3x+8\\-3x+7+3x-8=0\\1=0[/tex]

If c < 8 then there're no solutions. (the equation is false)

[tex]-3x+9=-3x+8\\-3x+9+3x-8=0\\1=0[/tex]

If c > 8 then there're no solutions.

easy way. also if you look at the graph. It's literally impossible to have one intercept if the coefficient of x for both have the same operators and same absolute value like -2x+c = -2x + a or -3x+2 = -3x+5, we'll never get a single intercept. If we change like -3x+c = -5x+8, we might still get one solution.

Answer:

I think C 130 probably wrong

Answer:

130 degrees

Step-by-step explanation:

Since there are vertical angles 2x and 3x-50 are the same. So you would do 2x=3x-50. The picture below shows how I got x=50. SO now you know x=50, it's important to remember that line AC equals 180 degrees. So what you nees to do is 180-50 to get what y equals. y should equal 130 degrees.

the final answer is -17

Answer:

-17

Step-by-step explanation:

23+(8-5)*4-52

1. Solve parentheses- 8-5=3 so                                        23+3*4-52

2. Then do multiplication- 3*4=12,                                    23+12-52

3. Then add or subtract but go left to right23+12=35     35-52

4. Subtract, 35-52=-17                                                       -17          

Answer:

Yes, Jean is correct

Step-by-step explanation:

Given

[tex]73 * \frac{3}{4}[/tex]

Required

Determine the value of the result

When a positive integer is multiplied by a fraction, the result is always less than the integer

Solving further

[tex]Expression = 73 * \frac{3}{4}[/tex]

[tex]Expression = \frac{73 * 3}{4}[/tex]

[tex]Expression = \frac{219}{4}[/tex]

[tex]Expression = 54.75[/tex]

The result of the expression shows that the resulting value is less than 73.

Hence, Jean is correct

Answer:

x=4  

-5y+8x=-18        

linear combination:

cancel out -5y with 5y. combine 8x and 2x

5y+2x=58        

10x. combine -18 and 58 to get 40

10x=40    

40/10=4

x=4

Answer:

[tex] \boxed{ \huge{ \bold{ \boxed{ \sf{y = 3}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 5y - 25 = - 40}[/tex]

Move 25 to right hand side and change it's sign

⇒[tex] \sf{ - 5y = - 40 + 25}[/tex]

Calculate

⇒[tex] \sf{ - 5y = - 15}[/tex]

Divide both sides of the equation by -5

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

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:

p=5, q=1

Step-by-step explanation:

5-1=4, 5^2-1^2=24

25-1=24

24=24

I just guessed and checked the solution for the answer

Answer:

p + q = 6

Step-by-step explanation:

p² - q² ← is a difference of squares and factors as

p² - q² = (p - q)(p + q) , then

p² - q² = 4(p + q) = 24 ( divide both sides by 4 )

p + q = 6

Answer:

x = (5 + √73) / 4 or (5 - √73) / 4

Step-by-step explanation:

2x² - 5x - 6 = 0

x = [5 ± √(25 - 4(2)(-6)] / 2(2)

x = [5 ± √(25 + 48)] / 4

x = [5 ± √(73)] / 4

x = (5 + √73) / 4 or (5 - √73) / 4)

Step-by-step explanation:

Answer/Step-by-step explanation:

Length of AC:

Given that AB = x + 2, and BC = 7x - 3, therefore,

[tex] (x + 2) + (7x - 3) = AC [/tex] (segment addition postulate)

Simply the expression for the length of segment AC

[tex] x + 2 + 7x - 3 = AC [/tex]

Collect like terms

[tex] x + 7x + 2 - 3 = AC [/tex]

[tex] 8x - 1 = AC [/tex]

Length of QR:

Given that PQ = 8y + 5, and PR = 13y + 25, therefore,

QR = (13y + 25) - (8y + 5) (PQ + QR = PR)

Simplify the expression to for the length of segment QR

QR = 13y + 25 - 8y - 5

Collect like terms

QR = 13y - 8y + 25 - 5

QR = 5y + 20

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.
