Answer: yes
Step-by-step explanation: slope is 4/3 and y intercept is 8
m= Y-20/0-9
4/3= y-20/-9
4/3 x -9 = y-20
-12 = y-20
Y=20-12
Y=8
Answer:
3.4 grams
Step-by-step explanation:
The water 20g has salt solution of 17%.
If you were to evaporate all the water.
17% × 20
0.17 × 20 = 3.4
You would get 3.4 grams of salt.
Answer:
5
Step-by-step explanation:

Answer:
C
Step-by-step explanation:
In this technique, if we have to factorise an expression like ax2+bx+c, we need to think of 2 numbers such that:
N1⋅N2=a⋅c=1⋅−12=−12
AND
N1+N2=b=−1
After trying out a few numbers we get N1=3 and N2=−4
3⋅−4=−12, and 3+(−4)=−1
x2−x−12=x2−4x+3x−12
x(x−4)+3(x−4)=0
(x+3)(x−4)=0
Now we equate the factors to zero.
x+3=0,x=−3
x−4=0,x=4
