3 Factorise 5y - 6py​

Answer:

AC = 22

Step-by-step explanation:

AB + BC = AC , substitute values

4x - 6 + 4 = 2x + 10 , that is

4x - 2 = 2x + 10 ( subtract 2x from both sides )

2x - 2 = 10 ( add 2 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Then

AC = 2x + 10 = 2(6) + 10 = 12 + 10 = 22

Answer:

w = 6.

Step-by-step explanation:

5w + 3 = 4w + 9

5w - 4w = 9 - 3

w = 6

Then, check your work!

5(6) + 3 = 4(6) + 9

30 + 3 = 24 + 9

33 = 33

So, w = 6 will be the correct answer.

Hope this helps!

Answer:

Equation: [tex]3x-5+2x=90[/tex]

Angle measures: 52 degrees and 38 degrees

Step-by-step explanation:

Hi there!

We're given that the two angles form a right angle, which means they add up to 90 degrees.

Knowing this, we can construct the following equation:

[tex]3x-5+2x=90[/tex]

Now, we must solve for x:

[tex]5x-5=90\\5x=95\\x=19[/tex]

Therefore, x=19. Plug this into the expression for each angle to find their measures:

[tex]3x-5\\= 3(19)-5\\= 57-5\\=52[/tex]

[tex]2x\\=2(19)\\=38[/tex]

Therefore, the two angles measure 52 degrees and 38 degrees.

I hope this helps!

Answer:

25.7

Step-by-step explanation:

PQ=PR-QR

PQ=38.3-12.6

PQ=25.7 cm

Answer: PQ = 25.7 cm

Concept:

Here, we need to know the idea of the segment addition postulate.

The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Solve:

Given information

PR = 38.3 cm

QR = 12.6 cm

Given expression deducted from the segment addition postulate

PQ = PR - QR

Substitute values into the expression

PQ = (38.3) - (12.6)

Simplify by subtraction

PQ = [tex]\boxed{25.7cm}[/tex]

Hope this helps!! :)

Step-by-step explanation:

first term=1

common d=4

nth term=a+(n-1)d

7881=1+(n-1)4

7881=1+4n-4

7884=4n

Starting with n = 0, the n-th term in the sequence is

so any number in the sequence must have a remainder of 1 when divided by 4.

Answer:

The correct answer to the question is:

The difference between Shelly's and Terrence's total points.

Answer:

B

Step-by-step explanation:

The answer or the only choice you could pick, is D.

But it is not correct - not really.

The question says that 90x - 20 represents Terrence's points. Only if D is correct does 20 show his tasks. The question must have 2 answers.

So which one do you pick? You should never have to deal with this kind of question. The answer I think you need to give is B, but I wouldn't bet the farm on it.

The question should say 90*x - 20 has Terrence's tasks in it. Then the answer is B.

Answer:

Option I

Step-by-step explanation:

Let

[tex]f(x)=x^2+3x-28[/tex]

We know by subsitution,

[tex]f(-9)=(-9)^2+3(-9)-28=26>0[/tex]

[tex]f(0)=0^2+3(0)-28=-28<0[/tex]

[tex]f(5)=5^2+3(5)-28=12>0[/tex]

Since a quadratic equation only have 1 turning point, we know for some values a in (-9, 5) such that f(a)<0. And the option of the range of a must lie with in (-9, 5).

Therefore, only Option I is correct.

Answer:

The LCM of 25 and 200 is 200.

Explanation:

Find the prime factorisation of 25

25 = 5 × 5

Find the prime factorisation of 200

200 = 2 × 2 × 2 × 5 × 5

Multiply each factor the greater number of times it occurs in steps 1 or 2 above to find the LCM:

LCM = 2 × 2 × 2 × 5 × 5

LCM = 200

Answer:

the HCF of 25 and 200 is 25 because it divides both of them and is maximum factor of them.

LCM of 25 and 200 is 200 because it can be divided by both 200 and 25

Answer:

f(1) = 2 f(3) = 8 f(t) = 2^t

Step-by-step explanation:

you just plug in the number in the parenthesis next to f to x in the equation 2^x

Domain: [tex](-\infty,\infty)[/tex]

Range: [tex](0,\infty)[/tex]

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

Explanation:

I'm assuming the function is [tex]f(x) = 2(3)^x[/tex] which is an exponential function.

The domain of any exponential function is the set of real numbers. In interval notation, the domain is [tex](-\infty, \infty)[/tex] which says we can pick any number between negative infinity and positive infinity: aka any number we want. There are no restrictions to worry about such as division by zero errors.

The range of this exponential function is the set of y values such that y > 0. It often helps to see the graph of what is going on (see below). Note how as x heads to the left, and gets more negative, the curve approaches the x axis. It never actually touches it however. So it will never reach y = 0 itself but instead just get very close. The inequality y > 0 translates to the interval notation [tex](0,\infty)[/tex]

----------

Summary:

Domain: [tex](-\infty,\infty)[/tex];  Range: [tex](0,\infty)[/tex]

So that's why the answer is choice A

The domain and range of the function f(x)  are  (-∞, ∞) and  (-∞, ∞) respectively.

A relation is a function if it has only One y-value for each x-value.

The function f(x) = 2(3x) can be simplified to f(x) = 6x.

The domain of a function is the set of all possible input values for x, while the range is the set of all possible output values for f(x).

Since there are no restrictions on the value of x that can be plugged into the function, the domain of f(x) is all real numbers, or (-∞, ∞).

To find the range, we can look at the behavior of the function as x varies. As x increases or decreases, the value of f(x) also increases or decreases, respectively, at a rate of 6 times the rate of change of x.

Therefore, the range of f(x) is also all real numbers, or (-∞, ∞).
