Answer:

-10, -8

Step-by-step explanation:

a + b = -18

a * b = 80

Solve:

from the first eq.

a = 18 - b

replacing this value in the secon eq.

(18-b)*b = 80

18*b + b*-b = 80

-b² + 18b = 80

-b² + 18b - 80 = 0

b = {-18±√((18)² - (4*-1*-80))] /(2*-1)

b = {-18±√(324.320)} / -2

b = {-18±√4} / -2

b = {-18±2} / -2

b₁ = {-18-2} / -2 = -20/-2 = 10

b₂ = {-18+2} / -2 = -16/-2 = 8

The two number must be negatives, so the numbers are:

-10 and -8

Check:

-10 + (-8) = -10 - 8 = -18

-10*-8 = 80

Answer:

x = 5f - a

Step-by-step explanation:

6x + a = 5(x + f)

6x + a = 5x + 5f

x = 5f - a

Based on the information given, it should be noted that the supplement will be 48°.

It should be noted that two angles are called supplementary angles when the values that are added together will be equal to 180°.

In this case, we've been informed that one of the angles is 132°. Therefore, the value of the second angle will be:

= 180° - 132°

= 48°

The second angle is 48°.

In this problem, we're trying to find the supplement of [tex]\tt{132\textdegree}[/tex].

Supplementary angles add up to [tex]\tt{180\textdegree}[/tex].

So, let's find its supplement:

[tex]\tt{\angle x+132=180}[/tex], where x is the unknown angle.

Subtract 132 from both sides of the equal sign:

[tex]\boxed{\tt{\angle x=48\textdegree}}[/tex] [tex]\longleftarrow\tt{We\:conclude\:that\:this\:is\:the\:answer.}[/tex]

Answer:

x^2 - 5x -36

Step-by-step explanation:

multiply x-9 by x to get x^2 -9x. multiply x-9 by 4 to get 4x-36. add these two together to get x^2 - 9x + 4x - 36. simplify to get x^2 - 5x -36

Answer:

The slope is undefined.

Step-by-step explanation:

You can use slope formula (y - y)/(x - x) and you will get a zero on the bottom (never allowed) OR notice that the x's are the same so sketch a graph, the line is vertical...that means that slope is undefined.

Answer:

the answer is 224, if it is asking for the amount of megabytes she bought

Step-by-step explanation:

If she adds 2 megabytes each day, and after 64 days she only has 96 megabytes then

64 times 2 = 128

128 + 96 = 224

so 224 = the amount of megabytes she bought

Answer:

20% of 25 is greater

Step-by-step explanation:

25% of 16 = 4

20% of 25 = 5

Answer:

20% of 25

Step-by-step explanation:

To find 25% of 16, we have to consider how much 25% is out of 100%

25/100 can be simplified to 1/4

So 1/4 of 16 (or 16/4) = 4

To find 20% of 25, we have to consider how much 20% is out of 100%

20/100 can be simplified to 1/5

So 1/5 of 25 (or 25/5) = 5

4 < 5

Therefore, 20% of 25 is greater than 25% of 16

Step-by-step explanation:

the translation rule (x, y ) → (2x, [tex]\frac{1}{3}[/tex] y )

means multiply the x- coordinate by 2 and multiply the y- coordinate by [tex]\frac{1}{3}[/tex] ), so

A (- 1, - 3 ) → A' (- 2, - 1 )

B (4, - 3 ) → B' (8, - 1 )

Step-by-step explanation:

Rate of change means how much does the number of snowflakes go up each time (on a different question you might find the number goes down each time)

"Initial value" means whatthe number if snowflakes at step zero. We have to work backwards to find that number. For the equation, fill in the rate in front of the x (we use m for that number) and add in the initial value (b) in the format y=mx+b . The information for the table is in the picture (the step numbers and number of snowflakes)

The value of x = -5/2

To solve this question we must understand the concept of indices.

Indices in mathematics show the power to which an expression or variable is raised.

Here, the correct format of the equation given in the question as follows:

[tex]\mathbf{2 \sqrt[3]{3x +2}} \mathbf{= \sqrt[3]{4x -9} }[/tex]

[tex]2(3x+2)^{1/3} = (4x -9)^{1/3} \\ \\ (6x + 4)^{1/3} =(4x -9)^{1/3}[/tex]

Multiply the power of both sides by 3

(6x + 4) =(4x -9)

6x - 4x = -9 + 4      

2x = -5

x = -5/2
