help me please for brainlest

Answer:

my brain just died sorry

Step-by-step explanation:

Answer:

x = 6

4x2−10x=84

Step 1: Subtract 84 from both sides.

4x2−10x−84=84−84

4x2−10x−84=0

Step 2: Factor left side of equation.

2(2x+7)(x−6)=0

Step 3: Set factors equal to 0.

2x+7=0 or x−6=0

x=

−7

2

or x=6

Answer:

5 over 8

Step-by-step explanation:

convert the mixed numbers to improper fractions then divide them and simplify

equation: 7/2 ÷ 40/7 = 50/80 or simplify to 5/8

*the slash is supposed to be the line that separates the top and bottom number in the fraction*

Answer:

66

Step-by-step explanation:

Answer:

[tex]\huge\boxed{\sf 66\°}[/tex]

Step-by-step explanation:

Supplementary angles add up to 180°.

So,

The measure of the angle of supplement of 114° is:

=> 180° - 114° = 66°

[tex]\rule[225]{225}{2}[/tex]

Answer:

I= $3,000

Step-by-step explanation:

Giving the following information:

Klein opened a savings account that paid 5% simple interest with 6,000 in principal.

Number of periods= 10 years

To calculate the interest earned, we need to use the following formula:

I= P*r*t

P= principal

r= interest rate

t= time

I= 6,000*0.05*10

I= $3,000

Answer:

1/216

Step-by-step explanation:

Simplify the following:

6^(-3)

Hint: | In order to evaluate 6^3 express 6^3 as 6×6^2.

6^3 = 6×6^2:

1/(6×6^2)

Hint: | Evaluate 6^2.

6^2 = 36:

1/(6×36)

Hint: | Multiply 6 and 36 together.

6×36 = 216:

Answer:

1/1296

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

The answer is the first one. We've used that in previous questions.

B is wrong. It needs to be equal to something (180 in this case). B is also saying that the first angle is = to the sum of the other two. Not so.

C is wrong. the third angle's x term has to be plus.

D has the same problem.

Answer:

it would be right next to the other line

Answer:

Slope = -[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

To find the slope, you have to calculate the rise over run between two points.

[tex]\frac{rise}{run}[/tex] = [tex]\frac{2-(-1)}{(-4)-5}[/tex]

     = [tex]\frac{3}{-9}[/tex]

     = -[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

To find x,equate EF to BC

2y+x=14( from here,it's impossible to calculate the values yet)

Find the value of ‹ACB

180°-(99+45)=36°

Now equate ‹DFE to 36° to find y

8y-5=36

8y=36+5

8y=41

y=5.125

Plug in the value of y to find x

2y+x=14

x=14-2y

x=14-2(5.125)

x=3.75

9514 1404 393

Answer:

  x = -12

  y = 13

  FE = 14

  m∠E = 36°

  AB ≅ DF, BC ≅ FE, AC ≅ DE

  ∠D ≅ ∠A, ∠E ≅ ∠C, ∠F ≅ ∠B

Step-by-step explanation:

The expression involving y is that of an angle measure. In order to find y, we need to know the angle. So, it makes sense to start by identifying corresponding angles and their measures.

The congruence statement ΔABC ≅ ΔDFE means that ...

  ∠A ≅ ∠D . . . 45°

  ∠B ≅ ∠F . . . 99°

  ∠C ≅ ∠E . . . 180° -99° -45° = 36°

It also means ...

  AB ≅ DF . . . 10

  BC ≅ FE . . . 14

  AC ≅ DE . . . unmarked (and unknown*)

__

Using the measure of angle F we can solve for y:

  (8y -5)° = 99°

  8y = 104 . . . . . . divide by ° and add 5

  y = 13 . . . . . . . . divide by 8

Using the length of side FE, we can solve for x:

  2y +x = 14

  2·13 +x = 14 . . . . substitute for y

  x = 14 -26 . . . . . .subtract 26

  x = -12

_____

* The length of the unmarked side is unknown because its measure will depend on how you compute it. The given angles and side lengths are inconsistent, so the figure shown cannot exist. If angle measures are taken as accurate, the side measures are not, and vice versa.

Answer:

rate = 24*100/(400*2) = 3%

Step-by-step explanation:

Answer:

vertex = (- 1, 3 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = 2x² + 4x + 5 ← is in standard form

with a = 2, b = 4, then

[tex]x_{vertex}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1

Substitute x = - 1 into the equation for corresponding value of y, that is

y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3

vertex = (- 1, 3 )

Answer:

280 seats total

Step-by-step explanation:

90/100 = 252/x

To find x, cross multiply.

90x = 25,200

Divide both sides by 90 to get the variable alone.

x = 280 seats
