Answer:

x = -3, x = -2

Step-by-step explanation:

x² + 5x + 6 = 0

(x + 3)(x + 2) = 0

x + 3 = 0     x + 2 = 0

x = -3    x = -2

Answer:

x= 44

Step-by-step explanation:

Add 82+54.

Subtract 136 from 180. Giving you your answer.

Always subtract from 180 since a triangle is always 180.

Can you mark me brainliest? And 5 star?

Answer:

x= 44

Step-by-step explanation:

180 = 82 + 54 + x

180 = 136 + x

180 - 136 = 136 -136 + x

44 = x

Answer:

y= [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

change them to improper fractions

2 1/2= 5/2    1 2/3=5/3

divide y from 5/3:

[tex]\frac{5}{2} y=\frac{5}{3}[/tex]

mutiply each side by 2/5

y=10/15=2/3

here is your answer. change them to improper fractions

2 1/2= 5/2    1 2/3=5/3

divide y from 5/3:

mutiply each side by 2/5

y=10/15=2/3

Answer:

Step-by-step explanation:

step one:

let the number of Blu-rays  be b and

DVDS be d,

step two:

given that Blu-rays cost $25.99each and

DVDS cost $15.99 each,

we can model the cost of the Blu-rays and DVDS, as

100=25.99b+15.99d

hence the expression for the number of Blu-rays and DVDS, is given as

100=25.99b+15.99d

Answer:

-6/7, the first one

Answer:

[tex]\boxed {m = -\frac{6}{7}}[/tex]

Step-by-step explanation:

Use the Slope Formula to help determine the slope of the two following points:

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the two following points to the formula:

[tex](x_{1}, y_{1}) = (-3, 5)[/tex]

[tex](x_{2}, y_{2}) = (4, -1)[/tex]

[tex]m = \frac{-1 - 5}{4 + 3}[/tex]

-Solve for the slope:

[tex]m = \frac{-1 - 5}{4 + 3}[/tex]

[tex]m = \frac{-6}{7}[/tex]

[tex]\boxed {m = -\frac{6}{7}}[/tex]

Therefore, the slope is [tex]-\frac{6}{7}[/tex].

Step-by-step explanation:

Answer: D

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

d) x = 4/3

Step-by-step explanation:

Given equation,

→ -x + (3/7) = 2x - (25/7)

Now the value of x will be,

→ -x + (3/7) = 2x - (25/7)

→ -x - 2x = -(25/7) - (3/7)

→ -3x = -28/7

→ -3x = -4

→ x = -4/-3

→ [ x = 4/3 ]

Hence, the value of x is 4/3.

Answer:

The fractions are not equivalent. If you cross multiply 65 x 2 = 130 and 4 x 13 = 52. 130 > 52. Set them as a proportion. [tex]\frac{65}{4} = \frac{13}{2}[/tex]

They are not equal.

For 65/4 you cannot divide it by 2 and then get 13/2. You would get 32.5/2.

32.5/2 is not equal to 13/2

Answer:

A

Step-by-step explanation:

because if you put A into a calculator it equals 81.

hope this helps

Answer:

81 is the perfect square of the first option

Step-by-step explanation:

It is asking for the perfect square so the third option will be eliminated because that is cubed.

The fourth option will also be eliminated because it is multiplication.

The second option will be eliminated because it has addition.

81 is the perfect square of the first option

Answer:

[tex]-5*2[/tex] is larger.

Step-by-step explanation:

[tex]-5*2=-10[/tex]

[tex]-14+1=-13[/tex]

[tex]-10>-13[/tex]

-10 is greater because both numbers are negative, so -10 is the higher number.

Answer:

5 x 2 is the larger than -14 + 1.

Step-by-step explanation: -5 x 2 = -10, and -14 + 1 = -13. Plz tell me if you got it right.

answer:

72

step-by-step explanation:

your question doesn't make mathematical sense how can 12 = 6 then subract 90?

maybe you meant 12 + 6 - 90

if so

the answer is

72

(my work)

12 + 6 = 18

18 - 90 = 72

hope this helped <3

Answer:

2. z = 1 - 2·i    →    √5

3. z = 4 + 3·i   →      54

4. z = 6 - 8·i    →     10

1. z = √5 - i      →    √6

Step-by-step explanation:

1. z = √5 - i

The distance from the origin = √((√5)² +1²) = √(5 + (-1)²) = √6

Therefore, z = √5 - i → √6

2) z = 1 - 2·i

The distance from the origin = √(1² + (-2)²) = √5

Therefore, z = 1 - 2·i → √5

3) z = 4 + 3·i

The distance from the origin = √(4²+3²)) = √(16 + 9) = √25 = 5

Therefore, z = 4 + 3·i → 5

4) z = 6 - 8·i

The distance from the origin = √(6²+8²)) = √(36 + 64) = √100= 10

Therefore,  z = 6 - 8·i →  10

The square root of 20 = 4.47 so a for sure.

But the root of 20 is also -4.48 so that means that 2 and 3 are added to the list

Now what to do about - 8

(- 8)^2 = 64

The square root of 64 = +/- 8

It's kind of slippery but it depends on how you see the problem. It is a bit ambiguous.

I would eliminate - 8 but your instructor may not. Argue that it should not be included, but don't take the argument on forever. Let it go.

a for sure.

b and c I think so.

-8 is iffy.

Step-by-step explanation:

we know ,

area of circle =πr^2

hence we get from the figure that the diameter of circle is 19 cm and we can find radius

r=d/2

r=18/2=9cm

area of semicircle =πr^2/2

area of Semi circle equals to =22*(9)^2/7/2

=127.2857143

Answer:

Today: Sunday, 11 October 2020

Hour: 23.05 WIB (Indonesian)

_________________________

D = 18

r = 18 ÷ 2 = 9

area of semicircle = πr²/2

area of semicircle = 3.142 . 9²/2

area of semicircle = 3.142 . 81/2

area of semicircle = 254.502/2

area of semicircle = 127.251 cm²
