Answer:

(x-h) (y-k)

h=1

k=-5

Step-by-step explanation:

I don't really know what is the best way to answer it

Answer:

Sp = ₹250

Gain = ₹50

CP = SP - Gain

CP = ₹(250 - 50)

CP = ₹ 200

Gain = ₹50

Gain% = [tex]\frac{Gain}{CP}[/tex] × 100

= [tex]\frac{50}{200}[/tex] × 100

Gain% = 25%

Hope it will help you.

Answer:

11 pounds

Step-by-step explanation:

16 ounces equal a pound so you need to do 176 / 16 = 11

Answer:

The two triangles are congruent because the squares in the corner state it's 90 degrees, and the two tick marks show they are also congruent. \

Answer:

Yes

Step-by-step explanation:

Yes

ASA Criterion for Congruence

ASA Criterion stands for Angle-Side-Angle Criterion. Under ASA criterion, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.

Here Angle Q and Angle S are 90  

and side QR = RS

and Angle QRP = Angle SRT (Vertically opposite angles)

By that we can prove these two triangles are congruent

Answer:

i was gonna say 15 .(3x+12)=15

Answer:

D

Step-by-step explanation:

a - 3 = 7 ( add 3 to both sides )

a - 3 + 3 = 7 + 3 , that is

a = 10

Answer:

Sodas(s) + Hot Dogs (d) =117

d =2s

s+2s = 117

3s = 117

s= 117÷3

s= 39 sodas

Hot Dogs =2s = 2x39 = 78

Answer:

  -1/5

Step-by-step explanation:

Divide by the coefficient of p/q:

  -25/5 × p/q / (-25/5) = 1 / (-25/5)

  p/q = -5/25

  p/q = -1/5 . . . . in reduced form

Answer:

The tree was 33.6 meters tall.

Step-by-step explanation:

So the question is "How tall is the tree?" I take it.

tree height/shadow length = ladder height / shadow length

Notice that the heights are both in the numerator. A proportion should always do this. It should have the same units on either the two denominators or the 2 numerators.

x / 42 = 2.4 / 3                  Multiply both sides by 42

x = 42 * 2.4 / 3

x = 100.8 / 3

x = 33.6

Answer:

33.6

Step-by-step explanation:

x/42 = 2.4/3

x = 2.4/3 x 42

x = 2.4/1 x 14

x = 33.6/1

x = 33.6

Answer:

a₅₂ = - 212

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 8 and d = a₂ - a₁ = - 12 - (- 8) = - 12 + 8 = - 4 , then

a₅₂ = - 8 + (51 × - 4) = - 8 - 204 = - 212

Answer:   - 8.3c - 15

Step-by-step explanation:

(-2c + 5) + (-6.3c - 20)

-2c + 5 - 6.3c - 20

-2c - 6.3c - 20 + 5

- 8.3c - 15

Step-by-step explanation:

new salary = 50000(1+(6/100))=50000×1.06= RS53000

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 1, 4 ] , then

f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36

f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then

average rate of change = [tex]\frac{-36-(-6)}{4-(-1)}[/tex] = [tex]\frac{-36+6}{4+1}[/tex] = [tex]\frac{-30}{5}[/tex] = - 6

Answer:

It's B which would be -26

Answer:

The answer is b

Step-by-step explanation:

Answer: x = 4

Step-by-step explanation:

To solve this problem, make use of the fact that you may add anything to an equation, as long as you do it to both sides.

Simply add 4x to both sides to get:

13 = 1 + 3x

Then simply add -1 to both sides to get:

12 = 3x

Then, divide both sides by 3 to get:

4 = x

Answer:

6

Step-by-step explanation:

for 3 they need 4 cans of paint and for 2 they need 5 they add 1 too it everytime so 6

Step-by-step explanation:

False

If the positive number is greater than the negative, then it will stay positive.

say the question is 5+ -3.

The answer would be 2

Answer:

False

Step-by-step explanation:

It depends on what sign the larger number is. For example, -5+9= 4 because they are opposite signs and 9 is the larger number of the two, therefore the answer is a positive 4.

Answer:With 3.5 persons per square kilometre, Canada is one of the countries with the lowest population densities in the world. Census metropolitan areas (CMAs) with the highest population densities—Toronto (866), Montréal (854), Vancouver (735), Kitchener (546), Hamilton (505), and Victoria (475)—were located close to United States border.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Start by using the distributive property with 2(x+1) --> 2x+2

2. Your equation will be 2x + 5 = 3 + 2x + 2

3. Add the 3 and the two on the left side to be 5 + 2x

4. Your equation will be 2x + 5 = 5 + 2x

5. Now minus 2x from both sides so the 2x will cancel out

6. 5 = 5

Answer:

-2n-3

Step-by-step explanation:

-5 , -7 they go up in steps of -2

but it was -2n this would be how it would go

a) -2 -4 -6 -8

which you can see is -3 off each time

so -2n which is a)  

and then -3

= -2n-3

Triangle PQR is an isosceles triangle (b).

The sides PQ & QR are equal (8 cm each). If the opposite sides in a triangle are equal then it's an isosceles triangle.

RainbowSalt2222 ☔

Step-by-step explanation:

2(x + 10) = 3x - 30

2x + 20 = 3x - 30

2x - 3x = -30 - 20

-x = -50

x = 50°

Answer:

$3,619.09

Step-by-step explanation:

liam deposits $2400 into an account that earns 8.3% interest compounded quarterly.

Compound interest formula is

where A is the final amount

P is the initial amount deposited

r is the rate of interest

n is the compounding period

t is the time in years

P= 2400, r= 8.3%= 0.083, t=5, n=4 (quarterly)

Plug in all the values

A= 3619.09
