Use the expression -3/7+10
Aleks [24]

Answer:

a. Jake told the negative value of the expression which cannot be equivalent to the original expression.

b. 10 - $ \frac{\textbf{3}}{\textbf{7}} $ g

Step-by-step explanation:

a. The given expression is: $ \frac{-3}{7}g + 10 $

Multiplying through out by -, we get:

$ - 10 + \frac{3}{7}g $ which was the expression given by Jake. Since, it is the negative of the original one, they cannot be equivalent.

b. $ -\frac{3}{7}g + 10 = 10 - \frac{3}{7}g $

$ = \frac{70 - 3g}{7} $

Hence, the answer.

Write the equation of the line that is parallel to y=1/4x+5 and passes through (2,-9)
Tamiku [17]

Answer:

The answer is

<h2>y =  \frac{1}{4} x -  \frac{19}{2}</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

From the question the original line is

y=1/4x+5

Comparing with the general equation above

Slope = 1/4

Since the lines are parallel their slope are also the same

Slope of parallel line = 1/4

So the equation of the line using point

(2,-9) and slope 1/4 is

<h3>y + 9  =  \frac{1}{4} (x - 2) \\ y + 9 =  \frac{1}{4} x -  \frac{1}{2}  \\ y =  \frac{1}{4} x -  \frac{1}{2}  - 9</h3>

We have the final answer as

<h3>y =  \frac{1}{4} x -  \frac{19}{2}</h3>

Hope this helps you

Solve each of the following literal equations for c: (c/b) - x = 2d and ac + bd = x
maks197457 [2]
(c/b) - x = 2d
(c/b) = 2d + x
c = b(2d + x)
c = 2db + bx

ac + bd = x
ac = x - bd
c = (x - bd) / a OR c = (x/a) - (bd/a)
