Venita is factoring the expression 32 a b minus 8 b. She determines the GCF and writes the factored expression as 8 b (4 a minus 0). Which best describes Venita’s error?

2x + y = -4

slope = -2

perpendicular slope = 1/2

new equation = x - 2y = x

(1) (2)= 2

(-2) (-8)=16

2+16 =18

new equation = x - 2y = 18

Answer:

Step-by-step explanation:

If AB and DE are equidistant from the center, that means that they are the same length. We set the equations equal to one another and solve for x:

3x - 7 = 5(x - 5) and

3x - 7 = 5x - 25 and

18 = 2x so

x = 9. Now we sub that into the expression for AB (or DE since they're the same length):

3(9) - 7 = 20

Both AB and DE measure 20 units.

Answer:

8.94 m

Step-by-step explanation:

Use the Pythagorean Theorum - [tex]a^2 + b^2 = c^2[/tex]. Use leg 1 as a, leg 2 as b, and the third side as c.

We know leg 1 is 4, and that leg 2 is twice as long as leg 1...

[tex](4)^2 + (4*2)^2 = c^2[/tex]

Now, we use the Order of Operations to find [tex]c^2[/tex]...

[tex]4^2+8^2=c^2\\16+64=c^2\\80=c^2[/tex]

Now, we find the square root of [tex]c^2[/tex] to find c...

[tex]\sqrt{80} =8.94[/tex]

So, the length of the third side is 8.94 m.

Since the line divided the top angle into two equal pieces we call this an angle bisector.

Answer:

y = [tex]\sqrt{16}[/tex] x

that is equal to  y = 4x

[tex]\sqrt{16}[/tex] = 4

when graphing (x,y) the x is the horizontal value of the point (east west)

and the y in the vertical (north south) ....

if you have y = x it would be a 45 degree line that goes from the lower left to the upper right....

if you compare the red line  the point  1,1  (y=x) versus 1,4 (y=4x) in the blue line you will see that it is "stretched" upward

Answer:

Take the gross amount of any sum (items you sell or buy) – that is, the total including any VAT – and divide it by 117.5, if the VAT rate is 17.5 per cent. (If the rate is different, add 100 to the VAT percentage rate and divide by that number.)

Answer:

divide by 117.5 if the rate different, add 100 to the percentage and divide by the number therefore multiply by 100 to get the total

Step-by-step explanation:

2. The distance from one base of the prism to the other base of the prism, d = 10 mm

The thickness of each triangle to be used to fill the prism, t = 0.5 mm

The number of triangles needed, n, is therefore;

[tex]n = \dfrac{d}{t}[/tex]

Where;

d represents the distance between the bases of the prism, t, represents the thickness of each triangle, and n represents the number of triangles it would take to fill up the prism

Therefore;

[tex]n = \dfrac{10 \, mm}{0.5 \, mm} = 20[/tex]

The number of triangles it would take to fill up the prism, n = 20

Answer: u = [tex]\frac{7}{8}[/tex] or 0.875

Step-by-step explanation:

Let us convert this statement to a question

[tex]4^{2}[/tex]-8u-9 = 0

16-8u-9 = 0

-8u = 0+9-16

-8u = -7

u = -7 ÷ -8

u = [tex]\frac{7}{8}[/tex] or 0.875

Answer:

Step-by-step explanation:

The rabbit will jump on the train after the train moves 0.4km

The given parameters are:

[tex]d = 100m[/tex] -- distance between the puppy and the train

[tex]s_1 = 8km/hr[/tex] -- the speed of the train

[tex]s_2 = 10km/hr[/tex] --- the puppy's speed

Required

The distance where the puppy catch up with the train

First, we calculate the relative speed (rs) of the puppy to the train

[tex]rs =s_2 - s_1[/tex]

[tex]rs =10km/hr - 8km/hr[/tex]

[tex]rs =2km/hr[/tex]

Calculate the time to catch up with the train using:

[tex]Time = \frac{Distance}{Speed}[/tex]

[tex]t = \frac{100m}{2km/hr}[/tex]

Convert km to m

[tex]t = \frac{100m}{2*1000m/hr}[/tex]

[tex]t = \frac{100m}{2000m/hr}[/tex]

[tex]t = 0.05hr[/tex]

Calculate the distance to catch up with the train using:

[tex]Distance = Speed * Time[/tex]

[tex]d= s_2* t[/tex] --- speed of the train multiplied by the time

So, we have:

[tex]d = 8km/hr * 0.05hr[/tex]

[tex]d = 8km * 0.05[/tex]

[tex]d = 0.4km[/tex]

Answer:

Ishaan is currently 15 years old.

Step-by-step explanation:

Let B represent Ben's current age and I represent Ishann's current age.

Ben is four times as old as Ishaan. In other words:

[tex]B=4I[/tex]

Six years ago, Ben was six times as old as Ishaan. In other words:

[tex]B-6=6(I-6)[/tex]

Solve for I. Substitute:

[tex](4I)-6=6(I-6)[/tex]

Distribute:

[tex]4I-6=6I-36[/tex]

Subtract 4I from both sides and add 36 to both sides:

[tex]2I=30[/tex]

And divide both sides by two. Hence:

[tex]I=15[/tex]

Ishaan is currently 15 years old.

Answer:

Age of Ishaan = 15 years

Step-by-step explanation:

Let Ishaan's age = x years

Age of Ben = 4 * x = 4x years

6Years ago:

Age of Ishaan = x - 6

Age of Ben = 4x - 6

6 years ago, Ben was 6 times as old as Ishaan

So, Age of Ben = 6 * Ishaan's age

     4x - 6 = 6 *(x-6)

4x - 6 = 6x - 36

Add 36 to both sides

4x - 6 + 36  = 6x  

4x + 30 = 6x

Subtract '4x' from both sides

30 = 6x - 4x  

30 = 2x

2x = 30

Divide both by 2 sides

x = 30/2

x = 15

Answer:

f(x) = 1/2x + 6

Step-by-step explanation:

So before we even look at the first given formula, let's use the second formula: f(x) = -5.

Plug this formula into the x:

0 <= -5 <= 7

Is this true? Is -5 greater than or equal to 0 and less than or equal to 7?

No, this is false.

So the formula, f(x) = -5, is not the graph of f.

That only leaves one possible option!

Answer: £21007.22

Step-by-step explanation:

First, find the interest amount using the formula SI = (P × R × T) / 100.

SI = (P × R × T) / 100 = (18790 × 5.9 × 2)/100 = 221722/100 = £2217.22

The total amount = principle amount + interest amount

= £18790 + £2217.22 = £21007.22
