Choose the slope-intercept form of 3x + 2y = 5.

y =3/2x-5/2

y = -3/2x+5/2

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

Answers

Answer 1

Answer:

y = -3/2 x + 5/2

Step-by-step explanation:

3x + 2y = 5

2y = 5 - 3x

y = -3/2 x + 5/2

Answer 2

Answer:

y= -3/2x+5/2

Step-by-step explanation:

3x + 2y = 5

2y= 5- 3x

y= 5/2 - 3/2x

y= -3/2x+5/2

Answers

First take triangle BDH. We know B is 46 degrees and D is 33 degrees. Since the angles of a triangle equal 180 we get
180 - 46 - 33 = 101 for H.
H is supplementary to x, so their sum is also 180. This gives 180 - 101 = 79.
So x is 79 degrees.

2x^2+7x+3=0
O A. X=7
OB. X=4
OC. X=3
OD. X=-1/2
OE. X = 2
OF. X=-3

Answers

If X=7, the answer would be 150
If X=4, the answer would be 63
If X=3, the answer would be 42
If X=-1/2, the answer would be 0
If X=2, the answer would be 25
If X=-3, the answer would be 0



Therefore, OD. X=-1/2 and OF X=-3 are the answers that apply

The  solutions of the equation 2x²+7x+3=0 are x=-1/2 and x=-3.

What is quadratic equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

The given equation is 2x²+7x+3=0

Two times of x square plus seven times of x plus three equal to zero is the form of quadratic.

We can solve the quadratic equation  2x²+7x+3=0 using factoring

Let us find two numbers whose product is 2x²+7x+3=0 and

whose sum is 7.

We can see that 2x²+7x+3=0

Let us factor by grouping

2x²+6x+x+3=0

2x(x+3)+(x+3)

=(2x+1)(x+3).

x=-1/2 and x=-3

Therefore, the solutions are x=-3 and x=-1/2.

g(x) = x+9/x-9

g(x) . f(x) = x + 9/ x - 9 × (x+9)(x - 9)

What is the logarithmic function?

In mathematics, the logarithmic function is an inverse function to exponentiation. The logarithmic function is defined as

For x > 0 , a > 0, and a ≠1,

y= logₐ x if and only if x = a^y

Then the function is given by

f(x) = logₐx

Given here  log x= 3 ⇒x=10³

                                 ⇒x=1000

Hence, The value of x must be equal to 1000
