Answer:

X= [tex]\frac{1}{5\\}[/tex] y+ 1[tex]\frac{-1}{5}[/tex]

Step-by-step explanation:

y=5x+1

Step 1: Flip the equation.

5x + 1

Step 2: Add -1 to both sides.

5x + 1 + −1 = y+ −1

Step 3:

Divide both sides by 5.

[tex]\frac{5x}{5\\}[/tex]= [tex]\frac{y-1}{5}[/tex]

Answer:

  about 254.40

Step-by-step explanation:

Put the value where x is and do the arithmetic. (Any scientific or graphing calculator can do this for you.)

  f(6) = 325(0.96^6) ≈ 254.40

the answer is Y/g

y=fgx

y/g=fx,which mines f(x)=y/g

Answer:

(2)  x =  a + (bc - bd)^2.

Step-by-step explanation:

√(x - a)/ b  + d = c

√(x - a)/ b  = c - d

√(x - a)   = bc - bd

Squaring both sides:

x - a =  (bc - bd)^2

x =  a + (bc - bd)^2

_____________

Answer:

The numbers are 20 and 45

Step-by-step explanation:

Let the two numbers be a and b

The ratio of the two is 4:9

That means;

a/b = 4/9

9a = 4b •••••(i)

secondly;

Subtracting 5 from each gives a ratio of 3:8

(a-5)/(b-5) = 3/8

8(a-5) = 3(b-5)

8a - 40 = 3b - 15

3b - 15 + 40 = 8a

3b + 25 = 8a

a = (3b + 25)/8 •••(ii)

Insert this into 1

9(3b + 25)/8 = 4b

27b + 225 = 32b

32b - 27b = 225

5b = 225

b = 225/5

b = 45

From i;

9a = 4b

9a = 4 * 45

a = 4 * 45/9

a = 20

X+x+(x+10)=180

3x+10=180

3x=180-170

x=56.666666degrees.

Case 2

x+(x+10)+(x+10)=180

3x+20=180

3x=160

X=53.333333

When two angles of an isosceles triangle are given in the form of x, then the value of a single angle can have two possible outcomes those are:

Given,

Two angles: X and [tex]\rm{X}+10[/tex]

As we know in an Isosceles triangle, the sum of all the angles is equal to[tex]180^\circ[/tex] and any of the two angles can be equal.

There can be two possible outcomes:

Case 1. When the two equal angles are X

[tex]\begin{aligned}\text{X}+\text{X}+(\text{X+10})&=180\\3\text{X}+10&=180\\3\text{X}&=180-10\\\text{X}&=\dfrac{170}{3}\\\text{X}&=56.66^\circ\end{aligned}[/tex]

Case 2: When the two equal angles are [tex]\rm{X}+10[/tex]

[tex]\begin{aligned}\text{X}+(\text{X}+10)+(\text{X}+10)&=180\\3\text{X}+20&=180\\3\text{X}&=180-20\\\text{X}&=\dfrac{160}{3}\\\text{X}&=53.33^\circ\end{aligned}[/tex]

Therefore, the two possible values of X can be [tex]56.66^\circ[/tex] and [tex]53.33^\circ[/tex]

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The rate of change of the proportion y = 9x is 9.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

y = 4x  +2 is an equation.

x + 2x + 3 = 4 is an equation.

We have,

y = 9x

The rate of change of this equation can be calculated by finding its differentiation.

Now,

y = 9x

Differentiating with respect to x we get,

dy/dx = 9dx/dx

dy/dx = 9

Thus,

The rate of change of the proportion y = 9x is 9.
