Answer:
y = 2x + 3
Step-by-step explanation:
Given:
(2, 7) and (0, 3)
Find the slope between the two points:
(x1, y1) = (0, 3)
(x2, y2) = (2, 7)
(y2 - y1)/(x2 - x1)
(7 - 3)/(2 - 0)
4/2 = 2
m = 2
y = mx + a
y = 2x + a
Use one of the two points to find a (I will use point (2, 7):
7 = 2(2) + a
7 = 4 + a
a = 3
Slope-intercept Form: y = 2x + 3
Point-slope Form: y - 3 = 2x
Point-slope Form: y - 7 = 2(x - 2)
General equation: 2x - y + 3 = 0
200+70+6+1/10+3/100 i think thats the answer
Answer:
8. A
First step is to distribute - to 6x and 3. Next u want to combine like terms. So 2x^2-6x^2 = -4x^2. Next 4x - 6x = -2x. Again 9 + 3 = 12. Combine and u get -4x ^2 - 2x +12
9. C
First you add 4x to both sides. Then you subtract 55 leaving -45 greater than or equal to 9x. Then you divide by nine and you get -5 is greater than or equal to x
10. B
First you distribute 5 so 15 -3x < -2x +6. Next add 2 to both sides. Then subtract 15 leaving -3x < -9. Least divide by -3 and you get x > 3(the sign was swapped bc dividing by a negative number means it has to)
11. B
For this you could just distribute the equations and we on that 7•4=28. And 7•5=35. I'm this case both of the numbers have to be negative so 7 has to be negative as well
12. C
Distribute -2/3 and you get 9q^2-2q+14/3+5q^2
Then combine like terms and 9q^2+5q^2=14q^2. Order them and ur answer is 14q^2-2q+14/3
The answer is x = 10/3. You just have to add 21 to both sides of this equation then simplify. Hope this helped!
