Multiply both sides of the equation by 33.−x=−6⋅3-⁢x=-6⋅3
Multiply −6-6 by 33 to get −18-18.−x=−18-⁢x=-18
Multiply each term in −x=−18-⁢x=-18 by −1-1
x=18

2. Which equation represents y=-x2 - 10x-20 in vertex form?

Naily [24]

Answer:

$\large\boxed{y=-(x+5)^2+5}$

Step-by-step explanation:

The vertex form of a quadratic equation y = ax² + bx + c :

y = a(x - h)² + k

(h, k) - vertex

We have the equation

$y=-x^2-10x-20$

Convert to the vertex form:

$y=-x^2-2(x)(5)-20$

$y=-x^2-2(x)(5)-5^2+5^2-20$

$y=-(\underbrace{x^2+2(x)(5)+5^2}_{(*)})+25-20$ use (a + b)² = a² - 2ab + b²

$y=-(x+5)^2+5$

Daniel [21]

I think it is about rates; Ian can pay his parents back in roughly 16 months. Ken can pay his parents back in 30 months.

Ian: 1000$ / 60$m = 16.6 m

Ken: 600$ / 20$m = 30m

In a completely randomized design involving four treatments, the following information is provided. Treatment 1 Treatment 2 Trea

NeTakaya

Answer:

Option (b) 36.7

Step-by-step explanation:

Data provided in the question:

Treatment 1 Treatment 2 Treatment 3 Treatment 4

Sample Size 50 18 10 17

Sample Mean 32 36 42 48

Now,

The overall mean is calculated as

= $\frac{\sum_{i = 1}^{4} n_i X_i}{\sum_{i = 1}^{4} {n_i}}$

Here, Xi = Sample mean

n = sample sizes

Thus,

Overall mean

= [ (50 × 32) + (18 × 36) + (10 × 42) + (17 × 48) ] ÷ [ 50 + 18 + 10 + 17 ]

= [ 1600 + 648 + 420 + 816 ] ÷ 95

= 36.67 ≈ 36.7

hence,

Option (b) 36.7
