Slope intercept form and standard form

Mathematics
1 answer:
shtirl [24]2 years ago
8 0

Answer:

<em>First Equation: </em>

Slope Intercept Form: y=-1/2x+6

Standard Form: -1/2x+6

<em>Second Equation:</em>

Slope Intercept Form: y=1x-3 OR y=x-3

Standard Form: 1x-3 OR x-3

Step-by-step explanation:

We can just solve the equation by using the inequalities method.

<em>First Equation:</em>

y - 4 = - 1/2(x - 4)

y - 4= - 1/2x + 2

y = - 1/2x + 6

<em>Second Equation: </em>

y + 7 = 1/3(3x + 12)

y + 7 = 1x + 4

y = 1x - 3

Hope this helped!

A system of equations is graphed on a coordinate plane.
zavuch27 [327]

Answer:

Option C is correct.

(1, 4)

Step-by-step explanation:

A system of equation is given :

2x + 3y =12                 .....[1]

4x + 2y =10                 .....[2]

Multiply equation [1] by 2 both sides we get;

2(2x+3y) = 2(12)

Using distributive property i,e a \cdot(b+c) = a\cdot b+ a\cdot c

4x + 6y = 24                           .....[3]

Subtract equation [2] from [3] to eliminate x we get;

4x + 6y - 4x - 2y= 24 - 10

Combine like terms;

4y = 14

Divide both sides by 4 we get;

y = 3.5

Substitute the value of y in equation [1] we have;

2x + 3(3.5) =12

2x + 10.5 = 12

or

2x = 12 -10.5

2x = 1.5

Divide both sides by 2 we get;

x = 0.75

Solution = (0.75 , 3.5)

Best estimate solution =  (1, 4)

Therefore, the best estimate solution of the given system of equation is, (1, 4)

Simplify each.Assume that none of the variables is zero.​
Zanzabum

Answer:

2. 1 / a^2

3, 1

4. - 1

Step-by-step explanation:

Formulas : -

x^y / x^z = x^( y - z )

x^-y = 1 / x^y

x^y / x^y = 1

2.

a^2 / a^4

= a^( 2 - 4 )

= a^-2

= 1 / a^2

3.

m^6 / m^6 = 1

4.

- 8^4 / 8^4

= - 1 x 8^4 / 7^4

= - 1
