Answer:
3
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (2, - 4) , thus
y = a(x - 2)² - 4
To find a substitute (3, - 1 ) into the equation
- 1 = a(3 - 2)² - 4 ( add 4 to both sides )
3 = a
Thus
y = 3(x - 2)2 - 4 ← equation in vertex form
= 3(x² - 4x + 4) + 4
= 3x² - 12x + 12 + 4
= 3x² - 12x + 16 ← equation in standard form
with coefficient of x² term = 3
Answer:
9(8+y)
Step-by-step explanation:
simple addition, plz answer my question posted on my profile under "questions asked" and click my recent one. it would mean a lot.... thanks!!
First, let's find out how much the 6 boxes weigh. If one box of clay weighs 17.4 ounces, then how much does 6 boxes weigh? Well, let's multiply.
17.4 × 6 = 104.4
Next, let's find out how much clay each student get. Since there are 18 students and only 6 boxes, let's find this out by dividing the ounces.
104.4 ÷ 18 = 5.8
So, each student gets 5.8 ounces of clay. I hope this helps!
Answer:
87.0
Step-by-step explanation:
17.4
17x5=85
.4x5=2.0
85+2.0=87.0
The roots are 1, 1 again, and -5
