Find the measure of angle B in triangle ABC below.Explain

Answer:

X=2 & X=6

Step-by-step explanation:

If you graph the equation (I recommend using desmos) you can see that X equals 2 & 6.

Answer:

[tex]Ratio =16 : 31[/tex]

Step-by-step explanation:

Let

x = Freddie's age and y = His mother's age

Given

2001:=  [tex]x : y = 1 : 11[/tex]

2018:= [tex]x +17: y + 17= 2 : 5[/tex]

Required

The ratio of their age in 2030

[tex]x : y = 1 : 11[/tex]

[tex]x +17: y + 17= 2 : 5[/tex]

Express as fractions

[tex]\frac{x}{y} = \frac{1}{11}[/tex] --- (1)

[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex] -- (2)

In (1), make y the subject

[tex]\frac{x}{y} = \frac{1}{11}[/tex]

[tex]y = 11x[/tex]

Substitute [tex]y = 11x[/tex] in (2)

[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex]

[tex]\frac{x+17}{11x+17} = \frac{2}{5}[/tex]

Cross Multiply

[tex]5(x +17) = 2(11x + 17)[/tex]

[tex]5x +85 = 22x + 34[/tex]

Collect like terms

[tex]22x - 5x = 85 - 34[/tex]

[tex]17x = 51[/tex]

[tex]x =3[/tex]

[tex]y = 11x[/tex]

[tex]y = 11*3[/tex]

[tex]y = 33[/tex]

This means that: In 2001, Freddie was 3 and his mother was 33

In 2030 (29 years after);

Freddie will be: 3 + 29 = 32

His mother will be: 33 + 29 = 62

So, the ratio is:

[tex]Ratio =32 : 62[/tex]

Divide by 2

[tex]Ratio =16 : 31[/tex]

Answer:

The length of AB is 18

Step-by-step explanation:

Do the pygotham theorem

24^2 + 7^2 = 625

Square root the answer

[tex]\sqrt{625}[/tex] = 25

Line BO equals 7 because CO is 7 and they are both radiuses

Subtract the answer to the length BO

25 - 7 = 18

18 is the length of AB bro

Answer:

f(-3) = -2(-3)^3 - 3

f(-3) = 54 - 3

f(-3) = 51

g(3) = -5(3) + 4

g(3) = -15+4

g(3) = -11

Hope this helps!

Answer: (x-4) is not a factor of the given polynomial.

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

Explanation:

Rule: If (x-k) is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem. We can take this in reverse to say that if p(k) = 0, then (x-k) must be a factor of p(x).

In this case, we have k = 4 and we can find that:

p(x) = 2x^4-9x^3-20x^2+147x-180

p(4) = 2(4)^4-9(4)^3-20(4)^2+147(4)-180

p(4) = 24

The result we get is not zero, so that means (x-4) is not a factor of p(x).

Answer:

126 passengers from Trinidad.

Step-by-step explanation:

Given that,

On a BWIA flight, 2/3 of the  passengers are from Trinidad.

Total passengers = 189

We need to find how many were from Trinidad. It can be calculated by finding 2/3 of 189 such that,

[tex]P=\dfrac{2}{3}\times 189\\\\=126[/tex]

Hence, there were 126 passengers from Trinidad.

Answer:

x=1

Step-by-step explanation:

remember ll means absolute value

the absolute value of x is x and the absolute value of -7 is 7

now we have x+7=8

step 1 subtract each side by 7

7-7 cancels out

8-7=1

we're left with x = 1

Let me = slope

m = (13 - 5)/(6 - 2)

m = 8/4

m = 2

The slope is 2.

Answer:

Step-by-step explanation:

n-(7+n) which is a strange problem to give you as that is equal to

n-7-n which always equals -7

And that means n can be any real number and the expression still equals -7

The algebraic expression will be -7. x is the assumed algebraic expression. The equation is solved by subtraction.

An algebraic expression is a phrase that has been combined using operations like addition.

Let n is the number and x be the solution for the given condition;

If the number is decreased by 7 then the equitation will be (n-7).

From the given condition;

[tex]\rm x=\rm n-(n-7) \\\\ x=n-n-7 \\\\ x=-7[/tex]

Hence the algebraic expression will be -7.

Answer:

P' = 1/3 P

reflection in the y-axis just changes the sign of all the x-values.

Since P" ≅ P', and P' is smaller than P, P" cannot be ≅ to P

It is, however, similar to P.
