start by plugging in the value you already have, in this case, 5 for y.
-4x-3(5)=17
-4x-15=17
-4x=32
x=-8
however, since a is a+1, a would be 7 (making x 8)
also plz tell me if i read this wrong and it’s actually 1,5 rather than a+1 and 5 cause if i did i’m so sorry lol.
Answer:
(6,0)
Step-by-step explanation:
The given system has equations:
Multiply the top equation by 2 to get:
Subtract the top equation form the bottom equation to get:
Put y=0 into
Therefore the solution is (6,0)
Answer:
x=9
Step-by-step explanation:
7x-11 = 4x-2
7x-4x=11-2
3x=9
x=9
The answer is 5. Take 10 and divide that into 2 groups equally.
Area of the rectangular mat = 12 x 4 = 48 in²
Area of the 3 circles = 3( πr²) = 3(3.14 x 2²) = 37.68 in²
P(landing in a circle) = 37.68/48 = 157/200 = 0.79 (nearest hundredth)
Answer: The probability of landing in one of the circles is 0.79.
