[tex]−5(²+2−4)[/tex]

[tex]−5²−10+20[/tex]

Solution :—

[tex]−5²−10+20[/tex]

Answer:

Step-by-step explanation:

-5(x² + 2x - 4) = -5x² - 10x + 20

a = -4  ; b = -10  ; c = 20

D = b² - 4ac = (-10)² - 4*(-4)*20

   = 100 + 320 = 420

[tex]\sqrt{D}=\sqrt{2*2*3*5*7}=2\sqrt{105}\\\\x=\dfrac{-b+\sqrt{D}}{2a} \ ; x =\dfrac{-b-\sqrt{D}}{2a}\\\\\\x=\dfrac{10+2\sqrt{105}}{2*(-5)} \ ; \ x =\dfrac{10-2\sqrt{105}}{2*(-5)}\\\\\\x = \dfrac{2*(5+\sqrt{105})}{2*(-5)} ; \ x =\dfrac{2*(5-\sqrt{D})}{2*(-5)}\\\\\\x =\dfrac{5+\sqrt{105}}{-5} \ ; \ x=\dfrac{5-\sqrt{105}}{-5}\\\\\\x=\dfrac{-5-\sqrt{105}}{5} \ ; \ x =\dfrac{-5+\sqrt{105}}{5}[/tex]

Answer:

y = 2 when x =12

Step-by-step explanation:

y = k/x ..............as y varies inversely as x

8 = k/3

k = 8 * 3

k = 24

So,

y = k/x

y = 24/12

y = 2

Answer:

"y=32"

is the answer

Step-by-step explanation:

x=3 > y=8

x=3+3+3+3=12 then y=8+8+8+8=32

Answer:

  $95 per hour

Step-by-step explanation:

The total of charges is the sum of the cost of labor and the cost of parts. The cost of labor is the product of hours (5) and the cost per hour (x). Then the equation for total cost is ...

  total cost = parts cost + hours cost

  651 = 176 + 5x

  475 = 5x . . . . . . . subtract 176

  95 = x . . . . . . . . . divide by 5

The cost of labor per hour is $95.

The line is a vertical line, thus, the slope is not defined.

If we know that a line passes through two points (a, b) and (c, d), then the slope is given by the expression:

slope = (d - b)/(c - a)

Here we have the two points (9, 2) and (9, 27)

So the slope is:

slope = (27 -  2)/(9 - 9)

That tends to infinity, and this happens because this is a vertical line. So the slope is undefined.

Answer:

x=47

Step-by-step explanation:

all straight lines add up to 180°

we can work out x using this

we do:

180-86=94 to work out what 2x equals to

then we do

94/2=47 to find out what x equals to

x=47

Answer:

yes, because they are individual dots

Answer:

Answer:

5% of 600 is 30, then you multiply the 30 by the 4 years which gives you 120. then you add the original 600 with the 5 person from the four years which is 120 that comes to 720. so 720 is how much is in salma's account after 4 years.

Answer:

d = √149 = 12.2

Step-by-step explanation:

Distance between 2 coordinates: d = √[(x2 − x1)^2 + (y2 - y1)^2]

d = √[(0 - 7)^2 + (2 - -8)^2]

d = √[(-7)^2 + (10)^2]

d = √[49 + 100]

d = √149 = 12.2

Answer:

y=x÷20x19

Step-by-step explanation:

x÷20=5% then 5%x19=95% basically 5% off

Step-by-step explanation:

Pythagoras must be true :

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle), and it is always the longest of the 3 sides.

so, the sum of the squares of the 2 smaller numbers must be the square of the largest number.

1.3² + 2² = 1.69 + 4 = 5.69

that is NOT 3.2² = 10.24

so, this is NOT a right-angled triangle.

2.1² + 4² = 4.41 + 16 = 20.41

that is NOT 5² = 25

so, this is NOT a right-angled triangle.

5² + 12² = 25 + 144 = 169 = 13²

so, yes, this is a right-angled triangle.

Answer:

children = 177, adults =215

Step-by-step explanation:

im too lazy to write but solve this with a systeme

x(children),y(adults)

x+y=392

x=392-y

2.5y+1.25x=758.75

2.5y+1.25(392-y)=758.75

2.5y+490-1.25y=758.75

490+1.25y=758.75

1.25y=758.75-490

1.25y=268.75

y=268.75/1.25

y=215

x=392-215=177(number of kids)

Answer:

Question b

[tex]\textsf{Equation 1:} \ \dfrac12x-2y=-13[/tex]

[tex]\textsf{Equation 2:} \ x-4y=8[/tex]

Multiply Equation 2 by two:

[tex]\implies \textsf{Equation 3:} \ x+4y=-26[/tex]

Subtract Equation 2 from Equation 3:

[tex]\begin{aligned}x-4y & =8\\- \ \ \ x+4y & =-26\\\cline{1-2}-8y & =34\end{aligned}[/tex]

Solve for y:

[tex]\implies -8y=34[/tex]

[tex]\implies y = -\dfrac{17}{4}[/tex]

Substitute found value of y into Equation 2 and solve for x:

[tex]\implies x-4\left(-\dfrac{17}{4}\right)=8[/tex]

[tex]\implies x+17=8[/tex]

[tex]\implies x=-9[/tex]

Question a

[tex]\textsf{Equation 1:} \ x+y=2[/tex]

[tex]\textsf{Equation 2:} \ -3x-y=5[/tex]

Add Equation 1 and Equation 2:

[tex]\begin{aligned}x+y & = 2\\+ \ \ \ -3x-y & =5\\\cline{1-2}-2x & = 7\end{aligned}[/tex]

Solve for x:

[tex]\implies -2x=7[/tex]

[tex]\implies x = -\dfrac{7}{2}[/tex]

Substitute found value of x into Equation 1 and solve for y:

[tex]\implies \left(-\dfrac{7}{2}\right)+y=2[/tex]

[tex]\implies y=\dfrac{11}{2}[/tex]

Answer:

AAA and SSA are not real theorems

Step-by-step explanation:

Side Side Angle is not a valid theorem because the unknown side could be located in two different places which would not prove the triangles congruent.

Angle Angle Angle is also not a valid theorem because all the angles might have congruent measures but that doesn't mean the sides will have the same measures therefore AAA cannot prove triangles congruent.

The rest are valid congruence theorems.

Answer:

6 cm

Step-by-step explanation:

The area of a triangle is [tex]\frac{bh}{2} = A[/tex], where b = base, h = height, and A = area. In this case, we're given the height as 4 cm and the area as 6 cm^2.

Let's plug in these values.

Now, let's solve this algebraically.

Step 1: Multiply both sides by 2.

Step 2: Divide both sides by 4.

Step 3: Check if solution is correct.

Therefore, the base is 6 cm. (but don't put the cm in the box because it's already there)
