Answer: c. -3.8
Step-by-step explanation:
-9 1/5-10+2/5+2(14 1/2-70 simplifies to -46/5-10+2/5+2(29/2-7)
reduce numbers: -46/5-10+2/5+2x15/2
-46/5-10+2/5+15
-44/5+5= -19/5 = -3.8
Answer:slope=10.000/2.000=5.000
x-intercept=2/5=minus 0.40000
y-intercept=2/1=2.00000
Step-by-step explanation:
Answer:
-1 and 0
Step-by-step explanation:
X ^4+x = 0;
x*(x^3+1)=0;
x*[(x^3-x)+(x+1)]=0;
x*[x(x-1)(x+1)+(x+1)]=0;
x*(x+1)(x^2-x+1)=0;
Since x^2-x+1=0 has no intersection with the X-axis, there is no x value such that y=0
x=0 or -1
Answer:
4
Step-by-step explanation:
We have been given that it equals 19 when added to 3 and multiplied by 4 so follow these steps:
1. set the equation 4x+3=19
2. solve for x
4x+3-3=19-3
This is used to solve for x
3. 4x=16 is found
4. if 4x=16, we divide 16/4 and get 4!
That's your answer hope it helped!
Answer:
C) CA=40
Step-by-step explanation:
2y/(2y+4)=(2y+6)/4y
cross multiply
8y²=4y²+20y+24
4(2y²)=4(y²+5y+6)
divide both sides by 4
2y²=y²+5y+6
y²-5y-6=0
(y-6)(y+1)=0
So the answer must be either 6 or -1. Since it can't be a negative number, it must be 6.
CA=2(6)+4+4(6)
CA=12+4+24
CA=40
