Answer:

x = y - 2 / 2

Step-by-step explanation:

y = 2x + 2

2x + 2 = y

2x = y - 2

x = y - 2 / 2

Answer:

y/2 - 1 = x

Step-by-step explanation:

1. Subtract 2 from both sides. The equation will be y - 2 = 2x.

2. Divide both sides by 2. The equation will be (y - 2) / 2 = x.

3. Simplify the equation to y/2 - 1 = x.

Which inequality is graphed on the number line? please Hurry!!!
user100 [1]

Answer:

Option C

Step-by-step explanation:

From the number line given in the picture,

Blue arrow has the starting point at a = 6 (Dark point) and moving towards negative side of the number line.

Therefore, number line represents a ≤ 6

3a ≤ 3(6)

3a ≤ 18

3a - 11 ≤ 18 - 11

3a - 11 ≤ 7

Therefore, Option C is the correct option.

If p, q are zeroes of polynomial f(x) =2x^2-7x+3,find the value of p^2+q^2​
Elza [17]

Answer:

p^2 + q^2 = 22/9.

Step-by-step explanation:

For a quadratic function ax^2 + bx + c if the zeroes are A and B then

A + B = -b/a and AB =  c/a.

2x^2 - 7x + 3

Now p and q are the zeroes of the above function so

p + q =  7/3 and pq = 3/2.

Now p^2 + q^2 = (p + q)^2 - 2pq

= (7/3)^2 - 2* 3/2

=  49/9 - 3

= 49/4 -  27/9

= 22/9.

Given that a 90% confidence interval for the mean height of all adult males in Idaho measured in inches was [62.532, 76.478]. Wh
NNADVOKAT [17]

Answer:

The point estimate used to estimate the mean height of all adult males in Idaho is 69.505 inches.

Step-by-step explanation:

Each confidence interval has two bounds, the lower bound and the upper bound. The points estimate used to estimate the mean is the halfway point between those two bounds, that is, the sum of those two bounds divided by two.

In this problem, we have that:

Lower bound: 62.532

Upper bound: 76.478

Point estimate: (62.532 + 76.478)/2 = 69.505

The point estimate used to estimate the mean height of all adult males in Idaho is 69.505 inches.
