Answer:

we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.

Step-by-step explanation:

Given the expression

4 < -2x + 3 < 9

SECOND STEP

subtract 3 from the right-hand side as well as on the left-hand side

4-3

SOLVING THE REMAINING COMPLETE COMPRESSION

1 < -2x < 6

Divide all parts by -2

  • Please note that multiply or divide an inequality by a negative number flips the inequality sign.

so the expression becomes

\frac{1}{-2}\:

\frac{1}{-2}\:>x\:

Hence, from the explanation, we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.

Slope : - 9/7 point : ( -7,4 )
dolphi86 [110]
To form an equation with the given information, we use the formula :

y = mx + b, m being the slope and b being the y-intercept.

Since it is given that the slope is -9/7, we substitute m with -9/7.

y = -9/7x + b

To find b, we will substitute the known coordinates into the equation :
At point (-7 , 4), x = -7, y = 4

4 = -9/7 (-7) + b
4  = 9 + b
b = 4 - 9
b = -5

Now we know that b = -5, we will substitute b = -5 into the equation that we found earlier, y = -9/7 x + b :

y = - 9/7x - 5

To make it more readable, we can multiply the equation by 7:
7y = -9x - 5
7y + 9x + 5 = 0

-----------------------------------------------------------
Answer : 7y + 9x + 5 = 0
