1) true
2)false
Step-by-step explanation:
1) 5(3)+2(4) = 23
= 15+8=23
23=23
thus, (3,4) is solution for 5x + 2y = 23
2) 5(0)+2(4) =23
= 0+8 is not 23
thus, (0,4) is not solution for 5x + 2y = 23
Answer:
Step-by-step explanation:
1) if the point A has coordinates (-1;10) and the point B - (5;2), then it is possible to write common view of the required equation of the line:
2) if to substitute the coordinates of A&B into the common equation, then:
3) finally, in slope-intersection form:
3y= -4x+26; ⇔ y= -4/3 x +26/3.
P.S. the suggested way of the solution is not the only one.
Slope intercept is x=3, y=-3. Hope this helped!
Well, to add and subtract unlike fractions, you need to look at both fractions and look at their denominators. next, you need to find the LCD, or the least common denominator. for example : 1/3 + 3/5. what is the least common multiple of 3 and 5? its 15 . and after that , you multiply the top the same amount you multiplied the bottom by, example con. : 1/3 x 5/5= 5/15 and 3/5 x 3/3 = 9/15. then you add the products , 5/15 + 9/15 and you get 14/15.
