Answer:
Q = 3.2
Step-by-step explanation:
So basically you would first re-order the equation. 6.4 + Q = 9.6
Then after that you will move all the terms containing Q to the left and the rest of them on the right. After that you will -6.4 to both sides of the equation. Which will look like this.
6.4 + (-6.4) + Q = 9.6 + (-6.4)
Then you will combine the like terms.
6.4 + (-6.4) = 0.0
0.0 + Q = 9.6 + (-6.4)
<u>Q = 3.2</u>
Answer:
y = - 5x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 5x + y = 4 into this form by subtracting 5x from both sides
y = - 5x + 4 ← in slope intercept form
with slope m = - 5
Parallel lines have equal slopes, thus
y = - 5x + c ← is the partial equation
To find c substitute (- 1, 4 ) into the partial equation
4 = 5 + c ⇒ c = 4 - 5 = - 1
y = - 5x - 1 ← equation of line
