There are 1.5 L in 1,500mL. You can covert it by moving the decimal point over three.
1) To graph y = 2x +3, give 2 different value for x & find its related y value:
for instance if x = 0 , then y = 3
if x = 1, then y = 5
Plot The coordinates of A(90,3) & B(1,5). You need just 2 point to draw a line.
2) The inverse of y=2x+3
a) Switch the x & y ===> x=2y+3
b) subtract 3 from both sides ===> x-3=2y+3-3===> x-3 = 2y
c) divide both sides by 2 ===> (x-3) / 2 =2y / 2 ==> 1/2(x-3)=y
And the inverse function of y = 2x+3 is y= 1/2(x+3)
We know 1 meter = 3.28084 feet
So 1 square meter = 3.28084 × 3.28084 square feet.
Now to convert from square feet to square meters, we need to divide by 3.28084 × 3.28084.
The area given in the news paper advertisement is 1330 square feet.
So to convert to square meters we divide by 3.28084 × 3.28084
We get
1330 square feet = 
Hence 1330 square feet of area is equal to 123.56 square meters.
Answer:
Step-by-step explanation:
Answer:
there are two complex roots
Step-by-step explanation:
Recall that for a quadratic equation
y = ax² + bx + c
the solution given by the quadratic formula is
x = ( -b ± √discriminant) / 2a
if the discriminant is negative, the radical term will become √ (negative number), which we know gives complex solutions. Hence we can eliminate real roots as possible answers.
Also notice that the "±" sign in the quadratic formula means that you will get 2 possible solutions:
x = ( -b + √discriminant) / 2a
or
x = ( -b - √discriminant) / 2a
Hence we know we will get 2 solutions.
Combining our findings, we can conclude that if the discriminant is negative, we will get 2 complex roots.
