How do I solve this equation (5x+9) + (3x-2)

1 answer:

8 0

Okie, so you have 2 polynomials separated by a plus sign. If there were a number in front of the polynomial, you would need to factor, as well as if there was a negative sign. But there is just an addition sign so you just add as you would normally.
5x + 9 + 3x - 2 = 8x +7
I hope this helps :-)

(0,2.5)(4,2.5)...u will notice that the y's are the same.....that means this is a horizontal line and y will always be 2.5.

so u want a perpendicular line...going through (3,-1)...a perpendicular line would be a vertical line...and a vertical line is represented by x = a number...so look at ur points (3,-1)....what number is in the x spot ? It is 3.....so ur perpendicular line is : x = 3

(3,0) and (0,6)
Y= -2x + 6
0= -2x + 6
-6/-2 = 3
X= 3
(3,0)

Y = -2(0) + 6
Y=6
(0,6)

Answer:

Answer is 10/7

Step-by-step explanation:

[tex] (\frac{6}{10} )r = \frac{6}{7} \\ cancelling \: 6 \: on \: both \: sides \\ (\frac{1}{10} )r = \frac{1}{7} \\ \frac{r}{10} = \frac{1}{7} \\ r = \frac{10}{7} \: \\
