Step-by-step explanation:

[tex]an = a1 + (n - 1)d[/tex]

Question 8)

2,8,14

d=a2-a1

d=8-2=6

a77= 2+ (76)*6

a77= 2+456=458

a77= 458

Question 9)

-12,-17,-22

d= -17+12= -5

a82= -12+ (81)*(-5)= -12-405= 417

a82= 417

Question 10)

9,13,17

d= 13-9= 4

a49= 9+ (48)*4= 201

a49= 201

Answer:

the first answer choice

Step-by-step explanation:

if you do 1/3 times -9 its -3

Answer:

I think that it is 0.9.

Step-by-step explanation:

-11-(-11)=0. Then 7-(-2)=9

You have to add the sides so 3cm + 9cm which gives you 12 cm therefore....

X = 12 cm :D

The line 2x +3y = 1 is tangent to 4x^2 -9y^2 = 19

:

Solve the linear equation for y

:

1) y = -2x/3 +1/3

:

substitute for y in the equation of the hyperbole

:

4x^2 -9(-2x/3 +1/3)^2 = 19

:

4x^2 -9(4x^2/9 -4x/9 +1/9) = 19

:

4x^2 -4x^2 +4x -1 = 19

:

4x -20 = 0

:

4x = 20

:

x = 5

:

use equation 1 to get the value of y

:

y = -2(5)/3 +1/3 = -3

:

******************************************************************

solution is x = 5, y = -3 which is the point (5, -3)

:

check the solution

:

hyperbole

:

4(5^2) -9(-3)^2 = 19

:

100 -81 = 19

:

19 = 19

:

Line

:

2(5) +3(-3) = 1

:

10 -9 = 1

:

1 = 1

Answer:

I know for sure, x=110 and the interior of a triangle is 180 degrees added up, so it is definately less than 180 degrees for the 2 angles added up, I am not sure what y is I haven't done geometry for almost 2 years now sorry.

Answer:

z = -32

Step-by-step explanation:

5 = z/-4 - 3

Add 3 to both sides

8 = z/-4

Multiply both sides by -4

-32 = z

Answer:

e = -5

Step-by-step explanation:

-9e - 4 > 41

     +4    +4

-9e > 45

divide by -9 on both sides

e = -5

Answer:

The answer is 3

Step-by-step explanation:

Answer:

m= 2/3

Step-by-step explanation:

up 2 right 3

y= 2/3x-2

Answer:

m=2/3

Step-by-step explanation:

when it asks for m its asking for the slope and the slope of that line is 1/3

Answers:

(2, -3) and (3, -3)

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

Work Shown:

Since f(x) = -3, we'll replace f(x) with -3 and solve for x

f(x) = x^2 - 5x + 3

-3 = x^2 - 5x + 3 .... f(x) replaced with -3

0 = x^2 - 5x + 3 + 3 ... adding 3 to both sides

0 = x^2 - 5x + 6

x^2 - 5x + 6 = 0

(x - 3)(x - 2) = 0 .... factor; you can also apply the quadratic formula

x-3=0 or x-2=0

x = 3 or x = 2

So that explains where that '2' comes from when they listed (2, ?)

-------------

To find what replaces the question mark, we will plug x = 2 into the function

f(x) = x^2 - 5x + 3

f(2) = 2^2 - 5(2) + 3

f(2) = 4 - 10 + 3

f(2) = -3

We could have skipped this portion and said that the solution is (2,-3) but plugging x = 2 into the function to get the output y = -3 helps confirm that x = 2 is one of the x solutions.

-------------

Let's do the same for x = 3

f(x) = x^2 - 5x + 3

f(3) = 3^2 - 5(3) + 3

f(3) = 9 - 15 + 3

f(3) = -3

We end up with the same output, so x = 3 is confirmed as well.

The graph below visually helps reinforce these confirmations. Each solution  is an intersection between the two curves.

Answer:

£8997

Step-by-step explanation:

Given data

Mr Jones buys a new car for £14 995

let us find the value of 40% of  £14 995

=40/100* £14 995

= 0.4* £14 995

= £5998

Hence the car will cost

=£14 995- £5998

=£8997

Answer:

5 cups of water

Step-by-step explanation:

well if we take this and turn it into a ratio, we know the base is 3hrs/2cups

so if we want to find 7.5hrs/x then we just multiply the two fractions and see what we get. so 7.5 divided by 3 is equal to 2.5

so we take the amount of water she drinks in 3hrs which is 2cups of water and we multiply that by 2.5 leaving us with Danielle drinking 5 cups of water in 7.5 hours of ballet practice.

hope this helps if it did please leave a like, rate, and give me the brainliest is possible!

have a great day!

I would assume it would be 4.5 cups

Answer:

Answer Key 7-5 Thru 7-8

Step-by-step explanation:

Answer:

Step-by-step explanation:

The missing angle and the exterior angle, a, must equal 180 so

a+8x-11=180

a=191-8x

The sum of all inner angles must equal 180 so

191-8x+2x+6+5x=180

-x+197=180

-x=-17

x=17

Answer:

Equiangular Triangle (D)

Step-by-step explanation:

The points connect to make a right angle which has all equal angles.

Answer:

it's isosceles!

Step-by-step explanation:

the points form a right triangle, which eliminates equiangular without even thinking about it since equiangular triangles must have all equal angles, which is impossible with a 90 degree angle since all angles of a triangle add up to 180. Equilateral is also eliminated because the side lengths are not equivalent. Scalene is also eliminated because the two sides adjacent to the 90 degree angle are congruent. This leaves isosceles. It is isosceles because it has two congruent side lengths and two congruent angles.

Answer:

45 • 4 = 180

Step-by-step explanation:

1 quart = 1/4 gallon.

45 • 4 = 180

Step-by-step explanation:

x=2 y=0

x= -2 y= -4

y=mx+b

b= 2

-4 = -2m +2

-2m= -6

m=3

y= 3x +2

.......

x=0 y=4

x=2 y= 2

y=mx+b

b=4

2=2m+4

2m= -2

m= -1

y = -x +4
