By the Addition Principle of Equality, I would add 3.4 to both sides of the equation to get rid of the constant term -3.4 on the right-hand side.

12.7 + 3.4 = j - 3.4 + 3.4
16.1 = j

So, j is equal to 16.1.

12.7 = j - 3.4

We're simply just trying to get j by itself.

So, add 3.4 to both sides.

12.7 + 3.4 = j

Simplify.

16.1 = j

So, j = 15.1

~Hope I helped!~

What is the answer for m^2-5m-14=0?

tensa zangetsu [6.8K]

Answer: m = 7 or -2

Step-by-step explanation:

Quadratic Formula! $\frac{{-b (+/-)\sqrt{(b^{2}-4ac }}}{2a}$

Polynomial Form: $ax^{2} +bx+c$

So in this example a: 1 b: -5 c: -14

You get: $\frac{{-(-5) (+/-)\sqrt{((-5)^{2}-4(1)(-14) }}}{2(1)}$

m = 7 or -2

Check by plugging a value back in for m

$(7)^{2} -5(7)-14=0?\\(-2)^{2} -5(-2)-14=0?\\$

True for both.

39. State the equation for the line described below.

devlian [24]

Answer:

Step-by-step explanation:

39). y = $-\frac{7}{8}$ x + 3

40). m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

y - $y_{1}$ = m( x - $x_{1}$ )

(- 7, 5)

( - 12, 4)

m = ( 4 - 5 ) / ( - 12 + 7) = 1/5

y - 5 = (1/5)(x + 7) ⇒ y = $\frac{1}{5}$ x + 6.4
