D. x [tex]\leq[/tex] 4

Step-by-step explanation:

1. You add 6 to each side

2. Divide each side by 5 to isolate x

Answer:

answer is A.

Step-by-step explanation:

-5x-10 <20

Group like terms

-5x < 20 + 10

-5x < 30

Divide both sides by -5

Answer:

X=1.5, but I may be incorrect, hope this helps!

Step-by-step explanation:

FACTS I KNOW:

X has to be less than 2 but greater than 1

Angle B and D are 90 degrees

The complete bottom side is equal to 10

All triangle angles add up to 180 degrees

All angles in rectangles and squares are 90 degrees

All rectangles have 2 sets of 2 of the same sides.

If you take a piece of the top right you could make a rectangle

It would take about .5 of the 2

Therefore X=1.5 approximately, but I may be wrong.

For a function, each x term must correspond to exactly one y term. We can use the vertical line test to determine whether or not that holds true for the following 6 graphs. If each x term corresponds to exactly one y term, then any vertical line that we draw on the graph should hit the graph at only one point.

1. We can't draw a vertical line that hits the graph at more than one

point so this relation must be a function.  

2. We can draw many vertical lines that will hit the graph at more than one point. Thus, we can conclude the graph shown here is not a function.

3. We can't draw a vertical line that hits the graph at more than one

point so this relation must be a function.  

4. We can't draw a vertical line that hits the graph at more than one

point so this relation must be a function.  

5. We can draw many vertical lines that will hit the graph at more than one point. Thus, we can conclude the graph shown here is not a function.

6. We can draw many vertical lines that will hit the graph at more than one point. Thus, we can conclude the graph shown here is not a function.

Answer:

  obtuse

Step-by-step explanation:

The law of cosines tells you ...

  b² = a² +c² -2ac·cos(B)

Substituting for a²+c² using the given equation, we have ...

  b² = b²·cos(B)² -2ac·cos(B)

We can subtract b² to get a quadratic in standard form for cos(B).

  b²·cos(B)² -2ac·cos(B) -b² = 0

Solving this using the quadratic formula gives ...

  [tex]\cos(B)=\dfrac{-(-2ac)\pm\sqrt{(-2ac)^2-4(b^2)(-b^2)}}{2b^2}\\\\\cos(B)=\dfrac{ac}{b^2}\pm\sqrt{\left(\dfrac{ac}{b^2}\right)^2+1}[/tex]

The fraction ac/b² is always positive, so the term on the right (the square root) is always greater than 1. The value of cos(B) cannot be greater than 1, so the only viable value for cos(B) is ...

  [tex]\cos(B)=\dfrac{ac}{b^2}-\sqrt{\left(\dfrac{ac}{b^2}\right)^2+1}[/tex]

The value of the radical is necessarily greater than ac/b², so cos(B) is necessarily negative. When cos(B) < 0, B > 90°. The triangle is obtuse.

Answer:

63 units!!

Step-by-step explanation:

36x.75= 27

Add 27 to 36 to get the large pot.

Answer:

The large pot can hold 48 units of water.

Step-by-step explanation:

small pot holds 75% water of a large pot

small pot holds 36 units

let x be quantity of water in large pot

According to the question,

75% of x = 36 units

75/100 * x= 36

75x/100= 36

75x= 36*100

75x= 3600

x= 3600/75

x= 48 units

The large pot can hold 48 units of water.

Answer:

Question 2: The first function represents the amount of money she'll have from her 450 under her bed.

s(x) = 450

The second function represents the amount of money she'll earn from babysitting per hour (x):

a(x) = 6(x - 2)

To figure the combined amount, we can add the two functions:

f(x) = s(x) + a(x)

f(x) = 450 + 6(x - 2)

From there, she can simplify the function by distributing, then combining the like terms to simplify:

f(x) = 450 + 6x - 12

f(x) = 438 + 6x

Answer:

f(x) = 438 + 6x

Question 4: His functions are;

h(x)=$350

s(x)=(1.04)^x-1

To find total amount of money in Tommy's account using the functions above, we substitute the first equation x=$350 in the second function.

the angles that correspond are both next to one side

Answer:

Angle R= Angle V (given)

Angle Q = Angle T (given)

RQ = VT (given)

Therefore ∆PQR is congruent to ∆UTV

Step-by-step explanation:

3n^2

First term => n=1 => 3(1)^2 =>3

Second term => n=2 => 3(2)^2 =>3x4=12

Third term => n=3 => 3(3)^2 =>3x9=27

Fourth term => n=4 => 3(4)^2 =>3x16=48

Tenth term => n=10 => 3(1)^2 =>3x10=300

Answer:

{3, 12, 27, 48, 300}

Step-by-step explanation:

For the first four terms, n = {1, 2, 3, 4}.  For the tenth, n = {10}.

Then, applying the formula a(n) = 3n^2 to n = {1, 2, 3, 4, 10}, we get:

{3(1)², 3(2)², 3(3)², 3(4)², 3(10)²} = {3, 12, 27, 48, 300}

Answer:

B) 28 inches.

Step-by-step explanation:

After 1/8 of a ribbon is thrown away, the remaining part is cut into two pieces whose lengths are in the ratio 4 : 5.

And we want to find the length of the shorter ribbon from the two remaining pieces.

We are given that 9 inches of the original ribbon was thrown away. Since this is 1/8 of the total length, we can write that:

[tex]\displaystyle \frac{1}{8}L=9[/tex]

Where L represents the total length of the ribbon.

Solve for the total length:

[tex]\displaystyle L=72\text{ inches}[/tex]

So, the original length of the ribbon was 72 inches.

Since we threw away 9 inches of it, we now only have 63 inches.

This is then cut into two pieces in a ratio of 4 : 5. Let x represent the constant. Thus:

[tex](4x)+(5x)=63[/tex]

Solve for x:

[tex]9x=63\Rightarrow x=7[/tex]

Hence, the two remaining ribbons measure 28 inches and 35 inches.

Therefore, our answer is B.

Answer: 17

Step-by-step explanation:

In this problem, the phrase "a number" can be interpreted as a variable.  In this case, let the variable be "x."

Thus, "twice a number" = "2x"

"and 13" = "+ 13"

"is 47" = "= 47"

Thus, the problem is simply 2x + 13 = 47.

Then, simply subtract 13 from both sides to get 2x = 34.

Then, simply divide both sides by 2 to get x = 17.

Because "the number" is "x," the number is 17.

Answer:

y = -180 + 3x

Step-by-step explanation:

Because AB = AC -> ABC is a isosceles triangle -> B = C

Because AB = BD -> ABD is an isosceles triangle -> A = D -> x = D

We have ADB + ADC = 180 -> x + ADC = 180 -> ADC = 180 - x (1)

We have x = D, and BAD + ADB + ABD = 180 -> ABD = 180 - 2x but B = C -> C = 180 - 2x (2)

With (1) and (2) We have DAC + ACD + ADC = 180

-> y + 180 -2x + 180 -x = 180

-> y + 360 - 3x = 180

-> y = -180 + 3x

Answer:

y=3x-180
