Answer: (4, 5) 
Work:
Substitute the y in the second problem with y=x+1
3x-2(x+1)=5
3x-2x+1=5
x=4
Now solve for y
y=4+1
y=5

1st: You plug x+1 in for the value of y of the equation 3x-2y=5
2nd: Then you solve the equation 3x-2(x+1)=5
You will need to distribute the -2 into the x and 1 that is in the parentheses
You will then get 3x-2x-2=5
Then combine like terms which are 3x and -2x
You get x-2=5, then you will just add the 2 to both sides so then you will get x=7
3rd:Then you substitute the 7 that you just got in for the value of x for the equation y=x+1
4th:The equation would now be y=(7)+1
So then you will just add 7 and 1 together and you get y=8
*Your final answer is (7,8)*

Point S is on line segment RT given ST=3x-8, RT = 4x, and RS = 4x - 7, determine the numerical length of RT
seraphim [82]

Answer:

20

Step-by-step explanation:

Segment ST is half and RS is the other half. RT is the whole line so adding ST and RS will get you RT. 4x-7+3x-8=4x. solve for x which will get you 5. Replace the x with 5 in 4x (for segment RT) will get you an answer of 20 for the whole line.

Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which bestdescribes t
Katyanochek1 [597]
  • Discriminant Formula: b² - 4ac, with a = x^2 coefficient, b = x coefficient, and c = constant

So firstly, using our equation plug in the values into the discriminant formula and solve as such:

(-7)² - 4 × 3 × 4

49 - 48

1

So our discriminant is 1. <u>Since 1 is positive and a perfect square, this means that there are 2 real, rational solutions.</u>

Natalka [10]

Answer:

280

Step-by-step explanation:

first make a proportion. 7 over 250= x over 10,000. cross multiply to get 250x=70,000. 70,000 divided by 250 which gets you 280.
