Answer:

[tex]y=\dfrac{10}{3}[/tex]

Step-by-step explanation:

[tex]\left(\dfrac25\right)^{-3} \cdot\left(\dfrac52\right)^{-15} =\left(\dfrac25\right)^{2+3y}[/tex]

[tex]\textsf{Using exponent rule:}\left(\dfrac{a}{b}\right)^{-c} =\left(\dfrac{b}{a}\right)^{c}[/tex]

[tex]\implies \left(\dfrac25\right)^{-3} \cdot\left(\dfrac25\right)^{15} =\left(\dfrac25\right)^{2+3y}[/tex]

[tex]\textsf{Using exponent rule: } a^b \cdot a^c=a^{b+c}[/tex]

[tex]\implies \left(\dfrac25\right)^{-3} \cdot\left(\dfrac25\right)^{15} =\left(\dfrac25}\right)^2 \cdot \left(\dfrac25\right)^{3y}[/tex]

[tex]\implies \left(\dfrac25\right)^{12} =\left(\dfrac25}\right)^2 \cdot \left(\dfrac25\right)^{3y}[/tex]

[tex]\implies \left(\dfrac25\right)^{12} \div\left(\dfrac25}\right)^2 =\left(\dfrac25\right)^{3y}[/tex]

[tex]\textsf{Using exponent rule: } \dfrac{a^b}{a^c}=a^{b-c}[/tex]

[tex]\implies \left(\dfrac25\right)^{10} =\left(\dfrac25\right)^{3y}[/tex]

[tex]\textsf{Using exponent rule: } a^b=a^c \implies b=c[/tex]

[tex]\implies 10=3y[/tex]

[tex]\implies y=\dfrac{10}{3}[/tex]

Answer:

the slope intercept form of this line is y = -4x + 9.

Step-by-step explanation:

The equation of line is given by:

y = mx + b          .....[1]

where,

m is the slope of line

b is the y-intercept.

As per the statement:

Given: The rate of change = -4

Substitute in [1] we have;

y = -4x + b

Substitute the values of  any (x, y) from the given table.

Let x = -1 and y = 13

then;

13 = -4(1-)+b

⇒13 = 4+b

Subtract 4 from both sides we have;

9 = b

or

b = 9

⇒the equation become, y = -4x+9

Therefore, the slope-intercept form of this line is,  y = -4x+9

Answer:

are you sure its b? b doesnt seem to be present in 2x-y=6

Answer:

(3,0)

Step-by-step explanation:

We know the line will Pss through

(-2,5) and (2,1) so

let find the slope

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

So the slope is -1.

We know it passes through 2,1 so use point slope to find b.

[tex]y - 1 = - 1(x - 2)[/tex]

[tex]y - 1 = - x + 2[/tex]

[tex]y = - x + 3[/tex]

Set that equal to

[tex] {x}^{2} - 2x - y = 3[/tex]

[tex] {x}^{2} - 2x - 3 = y[/tex]

[tex] {x}^{2} - 2x - 3 = - x + 3[/tex]

[tex] {x}^{2} - x - 6 = 0[/tex]

[tex](x - 3)(x + 2) = 0[/tex]

[tex]x = 3[/tex]

Point (3,0).

Answer:

2[tex]\sqrt{3}[/tex] or ~3.464

Step-by-step explanation:

We see that the triangle ABC has an angle of 90° and 45°, so 90+45 is 135, and 180-135 is 45° which is a special triangle. The hypotenuse is k[tex]\sqrt{2}[/tex] and we know that k is 6 so the other side lengths are 6 since they are just k. Now the triangle CBD hares a side so it is 6 and the angles are  60° and 90° so the last angle is 30° which is another special triangle. Since the side length is 6 and it equals  [tex]\frac{\sqrt{3} }{2}[/tex]k. We divide 6 by [tex]\frac{\sqrt{3} }{2}[/tex] and we get 4[tex]\sqrt{3}[/tex] which is the value of k or the hypotenuse. To find x, we multiply k by 1/2 or divide it by 2. Dividing 4[tex]\sqrt{3}[/tex] by 2 gives us 2[tex]\sqrt{3}[/tex] which is x. If the question wants the exact number, then it is 3.464, otherwise, just put 2[tex]\sqrt{3}[/tex]. Hope this helps! (I'm not a bot btw)

Table 2 depicts the proportional relationship between x and y as 2/5 = 4/10 = 6/15.

Therefore,

1x / y

Simplifying the equation, then we get,

1/4  =  2 /8 =  3 / 12  = 6 / 24

=  2 / 8

y l x

Put the value of x and y in above equation,

4/1  = 8 /2 = 12/3

8/2

2, x/ y

5/2 = 10 /4

= 15 /6

30 /12

5 /  2

y l x

2/5 = 4 /10 = 6 /15

Hence, Table 2 depicts the proportional relationship between x and y as 2/5 = 4/10 = 6/15.

Hello your question is incomplete below is the complete question

Raj correctly determined that ray LH is the bisector of AngleGLI. A line contains points K, L, M. 4 lines extend from point L. One line extends to point F, another to G, another to H, and another to I. Which information could he have used to determine this? AngleGLH Is-congruent-to AngleILM mAngleKLM = 5mAngleILM ,   mAngleGLI = 2mAngleGLH, mAngleGLI = mAngleGLH + mAngleHLI

answer :  mAngleGLI = 2mAngleGLH

Step-by-step explanation:

The information that could have used to determine this information is

mAngleGLI = 2mAngleGLH

from the figure,  we can see that

mAngleGLI = mangleGLH + mangleHLI  

Hence  we can conclude mangleGLH = mangleHLI

therefore the  ray LH bisects angleGLI into two equal angles GLH & HLI.

Answer: mGLI = 2mGLH

Answer:

x = 6

Step-by-step explanation:

The perimeter is the sum of the 3 sides of the triangle. Sum the 3 sides and equate to 51, that is

15 + 5x - 6 + 2x = 51

7x + 9 = 51 ( subtract 9 from both sides )

7x = 42 ( divide both sides by 7 )

x = 6

By working with the exponential function, we will see that:

We know that the population of the cell doubles every four hours, then we can write:

y = 50*(2)^x

Where x is time in lapses of 4 hours, and 50 is the initial population of the cell.

In one day, there are 6 groups of 4 hours, then after one day we have:

In two days, there are 12 groups of 4 hours, then after two days we have:

In 3 days, there are 18 groups of 4 hours, then after 3 days there are:

Answer: d: -2,2

Step-by-step explanation:

The coordinates of W' after the rotation and the translation is (-2, 2).

Option D is the correct answer.

We have,

The rule for a rotation by 270° about the origin.

(x, y) → (y, −x)

Now,

W = (-4, -3)

Applying the rule.

W = (-3, 4)

Now,

A translation of 2 units down and 1 unit to the right.​

So,

W = (-3, 4)

W = (-3 + 1, 4 - 2)

W = (-2, 2)

Thus,

The coordinates of W' after the rotation and the translation is (-2, 2).

Answer:

g=7

Step-by-step explanation:

10g–7g–3=18

subtract 7g from 10 g

3g-3=18

add 3 to both sides

3g=21

divide each side by 3

g=7

Answer:

g=7

Step-by-step explanation:

We move all terms to the left:

10g-7g-3-(18)=0

We add all the numbers together and all the variables

3g-21=0

We move all the terms containing "g" to the left and all the other terms to the right

3g=21

g=27/3
