Answer:

1/2

Step-by-step explanation:

-2y= 8-X

y= -4+X/2

y= X/2-4

recall that: y= mx+c

in the equation y= x/2+C

m=1/2

where m is your slope

Answer:

x = 18

Step-by-step explanation:

Y = 90

Z = 25
X = 3x + 11

Triangle = 180

180 = 90 + 25 + (3x + 11) --> combine 90 and 25
180 = 115 + (3x + 11) --> minus 115 both sides
65 = 3x + 11 --> minus 11 both sides

54 = 3x --> divide 3 on both sides

x = 18

VERIFY:

3(18) + 11 = 54 + 11 = 65
65 + 90 + 25 =
155 + 25 = 180

Answer:

X = 18°

Step-by-step explanation:

As we can see it a right angled triangle

so <y =90°

Now

3x + 11° + 25° + 90° = 180°{being sum of angles of triangle}

3x + 126° = 180°

3x = 54°

X = 18°

Answer:

-1875

Step-by-step explanation:

An arithmetic sequence has a common difference as a sequence. Here the common differnece is -11.

So our sequence so far looks like,

(57,46,35,24....). We know the last term of the sequence is -207 and we need to find the nth term of that series so we use arithmetic sequence

[tex]a _{1} + (n - 1)d [/tex]

where a1 is the inital value,

d is the common differnece and n is the nth term.

We need to find the nth term so

[tex]57 + (n - 1)( - 11) = - 207[/tex]

[tex](n - 1)( - 11) = - 264[/tex]

[tex]n - 1 = 24[/tex]

[tex]n = 25[/tex]

So the 25th term of a arithmetic sequence is last term, now we can use the sum of arithmetic sequence

which is

[tex] \frac{a _{1} + a _{n} }{2} n[/tex]

[tex] \frac{57 + ( - 207)}{2} (25) = [/tex]

[tex] \frac{ - 150}{2} (25)[/tex]

[tex] - 75(25) = - 1875[/tex]

Answer:

-1875

Step-by-step explanation:

57 , 46 , ......... -207

[tex]First \ term = \ a_{1} = 57\\[/tex]

common difference = d = second term - first term = 46 - 57 = -11

[tex]n^{th} \ term = -207\\\\a + (n-1)*d=t_{n}[/tex]

57 + (n-1)* (-11) = -207

57 - 11n + 11 = -207

     -11n + 68  = -207

            -11n   = -207 - 68

             -11n  = -275

                 n = -275/-11

                n = 25

[tex]S_{n}=\dfrac{n}{2}(a_{1}+l)\\\\\\S_{25}=\dfrac{25}{2}*(57 + (-207) )\\\\\\ =\dfrac{25}{2}* (-150)\\\\\\= 25 *(-75)\\\\= -1875[/tex]

Answer:

5 and -8

Step-by-step explanation:

First, list the set of pairs of numbers that multiply to give 40 (so "factors" of 40):

1  40

2  20

4  10

5  8

Now look at the pairs to see which has a difference of 3.

1 and 40 has a difference of 39

2 and 20 has a difference of 18

4 and 10 has a difference of 6

5 and 8 has a difference of 3

Now all we need to do is determine whether 5 or 8 will be negative (if they are both negative, the product will be positive, so only one needs to be negative to have a product of -40).

As we need a final result of -3,  the two numbers will be: 5 and -8 (as 5 + - 8 = -3)

Answer:

5 and -8

Step-by-step explanation:

First I listed all the factors of 40 : 1, 2, 4, 5, 8, 10, 20 and 40.

Then out of those, I just had to find a pair with a difference of 3.

Or in other words, when I subtracted one from the other I either got 3 or -3.

The only pair that worked out that way when subtracted was 5 and 8.

However, if we multiply 5 and 8 we get 40, not -40, so something was amiss. When we add them up we have to get -3, and that only worked out if it was -8 and 5, since -8 + 5 = -3.

Therefore, the two numbers are -8 and 5

Hope this helps, please mark brainliest if possible :)

The area of a shape is the amount of space occupied by the shape

The area of the triangle is 216 square centimeters

The dimension of the triangle is given as:

Base = 27 cm

Height = 16 cm

The area of the triangle is then calculated as:

Area = 0.5 * Base * Height

So, we have:

Area = 0.5 * 27 cm * 16 cm

Evaluate the product

Area = 216 square cm

Hence, the area of the triangle is 216 square centimeters

Answer:

B

Step-by-step explanation:

Since the triangle has 2 equal base angles (45 degrees) and 1 angle is 90 degrees, the triangle is an isosceles right triangle.

We let a be the length of one side of the right angle, so the length of the other side is also a. Applying the Pythagorean theorem we have a^2 + a^2 =14^2 => a=[tex]7\sqrt{2}[/tex]

We have the area of an equilateral triangle 1/2 the product of the lengths of the 2 sides of the right angle. S=1/2*[tex]7\sqrt{2} * 7\sqrt{2}[/tex]=49

Answer:

D

Step-by-step explanation:

So when making these equations, there's always going to be an initial value and then a variable

In this case, x represents the unknown cost for each class that Janele took at the rock climbing gym.  She took 6 classes, so that's represented by 6x

50 is the initial value.  The initial value is a value that is constant, or stays the same.  It doesn't change based on variables like how many classes she took.  

The total cost of everything was 92 dollars

So then ur equation would be

6x + 50 = 92

Because both the initial cost of 50 dollars and the cost of the classes equal to 92

lol Janele and the quartz gym, some of these math problems really do be interesting.  like jim and his 100 watermelons from costco

Step-by-step explanation:

Look like BC is 15 and AC is 17

The Pythagorean Theorem states that a^2 + b^2 = c^2

so AC^2 = AB^2 + BC^2

17^2 = AB^2 + 15^2

289 = AB^2 + 225

AB^2 = 64

AB = 8

Answer:
