Answer:

Nothing is wrong with it

x= 1

Step-by-step explanation:

It has a solution; here is the solution.

(6x)(4x^7) = 24 x^ 7

x * 24x^7= 24x^7

x = 24x^7 / 24x^7

x = 1

Answer:

(6x)*(4x^7) = (6*4)*(x*x^7) = 24*x^8

(6x)*(4x^7) = 24*x^7 is wrong in calculation of x

Answer:

The transformation

$(x,y) \rightarrow (x-5,-y+1)$

maps triangle XYZ onto triangle X”Y”Z”.

Step-by-step explanation:

Let us take point Z on the XYZ triangle and see what sequence of transformations we have to apply to map it into the point Z''.

Now Z = (-2, 2) and Z'' = (-7, -1).

The x-coordinate goes from -2 ⇒ -7.

The y-coordinate goes from 2 ⇒ -1.

The x-coordinate is just shifted by -5; thus, $x \rightarrow x-5$ , and the y-coordinate first transforms as $y \rightarrow -y$ , and is then shifted by 1; thus, it transforms as $y \rightarrow -y+1$ .

So we have the full transformation

$(x,y) \rightarrow (x-5,-y+1)$

The area of a rectangle is 14 m2 , and the length of the rectangle is 3 m less than double the width. find the dimensions of the

muminat

Width =3.5, length = 4

Let's make a few equations to summarize what we know.:
a = 14
l = 2w -3
a = wl

Now let's substitute the expression for l into the expression for area and solve.
a = w(2w - 3)
a = 2w^2 - 3w
14 = 2w^2 - 3w

0 = 2w^2 - 3w - 14

which factors into
(2w - 7) (w + 2)

Solving for w
2w - 7 = 0
2w = 7
w = 3.5

w+2 = 0
w = -2

So w can be either 3.5 or -2. Since a negative width doesn't make sense, w = 3.5

Let's verify
w = 3.5
l = 2w - 3
l = 2*3.5 - 3
l = 7 - 3
l = 4
a = wl
a = 3.5 * 4
a = 14

So the width is 3.5 and the length is 4.

Ratio, Rate, and Speed

Andre45 [30]

Answer:

10:12:15

Step-by-step explanation:

a/b=5/6

b/c=4/5

thus

c/b=5/4

LCM of 4 and 6=12

5/6=10/12

5/4=15/12

b is the 12 in both

thus ratio between a:b:c is 10:12:15

i can reply in comments if more explanation is needed

What is the product of -2/7 and -3/6

Andrew [12]

Hey!

------------------------------------------------

Product means multiplication.

-2/7 * -3/6 = -6/42 = -1/7

------------------------------------------------

Hence, the answer is $\Large\boxed{\mathsf{-1/7}}$

------------------------------------------------

Hope This Helped! Good Luck!
