HELP PLEASE
20. What is vertex of the function f(x) = 2x2 – 12x + 10 ?
A. (-2, -8)
B. (3, 18)
C. (3, -8)
D. (2, 10)

Answer:

12.5

Step-by-step explanation:

We can use ratios to solve

4        4+6

---- = ----------

5         AC

4        10

---- = ----------

5         AC

Using cross products

4 * AC = 5*10

4AC = 50

Divide by 4

AC = 50/4

AC =12.5

Answer:

your answer is D. 24 cubic cm

Step-by-step explanation:

your welcome good day :)

Given:

Consider the expression is:

[tex]13-\dfrac{x}{5}+6.2y+20.5x-\dfrac{3}{8}y[/tex]

To find:

The like terms that can be combined in this expression.

Solution:

Two terms are called like terms, if they have same variables of same degree.

We have,

[tex]13-\dfrac{x}{5}+6.2y+20.5x-\dfrac{3}{8}y[/tex]

In the given expression, the pairs of likes terms are:

Pair 1: [tex]-\dfrac{x}{5}[/tex] and [tex]20.5x[/tex]

Pair 2: [tex]6.2y[/tex] and [tex]-\dfrac{3}{8}y[/tex]

It means [tex]-\dfrac{x}{5}[/tex] can be combined with [tex]20.5x[/tex] and  [tex]6.2y[/tex] can be combined with [tex]-\dfrac{3}{8}y[/tex].

Therefore, the correct option is C.

Answer:

1.5

Step-by-step explanation:

Applying,

Z = (x-μ)/σ................. Equation 1

Where Z = Z score for a height of 67 inches, x = height, μ = mean of the height, σ = standard deviation of the height.

From the question,

Given: x = 67 inches, μ = 64 inches, σ = 2 inches.

Substitute these values into equation 1

Z = (67-64)/2

Z = 3/2

Z = 1.5

Answer:

first option

Answer:

  1.2 t/m³

Step-by-step explanation:

1 tonne is 1 Mg = 10⁶ g

1 m³ is (100 cm)³ = 10⁶ cm³

The conversion is ...

  (1.2 g/cm³) · (1 t)/(10⁶ g) · (10⁶ cm³)/(1 m³)

  = 1.2(10⁶)/(10⁶) t/m³

  = 1.2 t/m³

__

For this conversion, the numerical value does not change. Megagrams per cubic meter is the same ratio as grams per cubic centimeter.

Answer:

k = 28

Step-by-step explanation:

[tex]t = 6n - 1 \\ 167 = 6k - 1 \\ 6k = 168 \\ k = 28[/tex]

Answer:

(0.88, 0,65)

Step-by-step explanation:

what do we have to do ? I assume we need to find the crossing point between the 2 lines.

when looking at the graphic, we can already rule out the first, third and fourth option.

none of the coordinates of that point is larger than 1 in any direction or smaller than 0.5.

so, just by looking at things I immediately "bet" on answer option 2 (0.88, 0.65).

but let's check.

y = -2x/5 + 1

y = 3x - 2

for the crossing point both functions must produce the same functional value.

=>

-2x/5 + 1 = 3x - 2

-2x/5 + 5/5 = 15x/5 - 10/5

-2x + 5 = 15x - 10

15 = 17x

x = 15/17 = 0.88...

y = 3×0.88... -2 = 0.65...

hurray, our original observation and "suspicion" is confirmed.

--273

Step-by-step explanation:

100th term is equal a1 + 99d so

100th term = 222 + (-5×99) = -273

Answer:

x = 55 degree

Step-by-step explanation:

let the another angle be y

y+108=125 (sum of two interior opposite angle is equal to the exterioe angle formed)

y=125-108

y=17

y+x+108=180 degree (sum of interior angle of a triangle)

17 + x + 108 =180

x + 125 =180

x = 180-125

x=55

Answer:

[tex]x = \frac{7}{4} [/tex]

Step-by-step explanation:

[tex]−8(4x−10)=24[/tex]

[tex] \frac{ - 8(4x - 10)}{ - 8} = \frac{24}{ - 8} [/tex]

[tex]4x - 10 = \frac{24}{ - 8} [/tex]

[tex]4x−10=−3[/tex]

[tex]4x=−3+10[/tex]

[tex]4x=7[/tex]

[tex]x = \frac{7}{4} [/tex]

Answer:

[tex]x= \frac{7}{4} [/tex]

Step-by-step explanation:

Let's solve:

[tex]−8(4x−10)=24[/tex]

Step 1: Simplify both sides of the equation.

[tex]−8(4x−10)=24 \\ (−8)(4x)+(−8)(−10)=24(Distribute) \\−32x+80=24[/tex]

Step 2: Subtract 80 from both sides.

[tex]−32x+80−80=24−80 \\ −32x=−56[/tex]

Step 3: Divide both sides by -32.

[tex] \frac{ - 32x}{ - 32} = \frac{ - 56}{ - 32}

\\

x= \frac{7}{4} [/tex]

Answer:

x - 6

Step-by-step explanation:

I am unfamiliar with such algebra tiles, but logically that set of tiles tells me :

1 x, -1, -1, -1, -1, -1, -1

so,

1×x + 6×(-1) = x - 6
