Answer:
5x - 2y = -10 (B.) This should be right so if its not let me know I am stumped on what else it would be
Step-by-step explanation:
Parallelism: Same slope but different y-intercept
1 - Get into slope formula
5x - 2y = 7
<u>- 5x -5x </u>
-2y = -5x + 7
-2y/-2 = -5x/-2 +7/-2
y = (5/2)x - 7/2
2 - Plug x and y from (0, 5) into y = mx + b however note the - 7/2 is extranneous and wont be used for b
y = (5/2)x + b
5 = (5/2)0 + b
5 = 0 + b
5 = b
Therefore
y = 5/2x + 5 is your slope formula.
Now to get x to the other side.
3 - Get it back to standard form.
y = 5/2x + 5
- 5/2x -5/2x
- 5/2x + y = 5
(Multiply 2 into everything to get rid of the fraction)
-5x + 2y = 10
Answer:
I cant lie I don't know this answer
Answer:
x=5,y=3
Step-by-step explanation:
the first step is to decide whether you want to substitute y and find x, or substitute x and find y.
(it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).
for example, let's substitute y into the first equation:
x=17-4*(x-2)
so now,we will organize the equation:
x+4x=17+8
5x=25/(÷5)
x=5
now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:
y=5-2
y=3
Answer:
the first plant would be 2x + 19 more than the second plant
Step-by-step explanation:
The computation is shown below:
Given that
There production levels are
9x + 14 and 7x - 5
Now
= 9x + 14 - (7x - 5)
= 9x + 14 - 7x + 5
= 2x + 19
Hence, the first plant would be 2x + 19 more than the second plant
Let makoha contribute x then njao contributes x * 3/2 = 1.5x
and odhiambo contributes 1.5x * 2.5 = 3.75 x
so we have the equation x + 1.5x + 3.75x = 120000
6.25x = 120000
x = sh 19,200 which is the amount for makhoa
Answer : amount contributed by odhiambo = 19,200 * 3.75 = sh 72,000
