Answer:
5
Step-by-step explanation:
x=3x-10 (x is the age)
2x=10
×=5
Its Between C and A For me but I will see what I get! but maybe this would help explain!
y = 2x + 4 is the equation and they want to know what the orderd pair of the point that crosses the y axis is. We don't know what the orderd pair means.
-------------------------
The y-axis contains all the points where x=0.
-----------------------
If y = 2x+4, let x=0 so you can solve for "y":
y = 2*0+4
<span>
y = 4</span>
You gotta combine like terms which would be 9x and 12x which gives you 21x .
It would be: 11 * 90/100
= 11 * 0.90 = 9.9
So, your final answer is 9.9
Hope this helps!
D. -4/3
Let's solve your equation step-by-step.
9x2+24x+20=4
Step 1: Subtract 4 from both sides.
9x2+24x+20−4=4−4
9x2+24x+16=0
Step 2: Factor left side of equation.
(3x+4)(3x+4)=0
Step 3: Set factors equal to 0.
3x+4=0 or 3x+4=0
x=
−4
/3
