Nikolay [14]

Answer:

Solve: x < 3 Graph: *attached* Interval Notation: (-∞,3)

Step-by-step explanation:

Solve:

combine like terms

$x + 5x -6 < 12$

$6x -6 < 12$

Add 6 on either side of the inequality

$6x < 18$

Divide by 6 on either side of the inequality

$x < 3$

Graph:

Elanso [62]

Answer:

2/ 5

Step-by-step explanation:

From the venn diagram, find tbe probability ;

P(work | sport)

Recall :

P(A | B) = P(A n B) / P(B)

From the venn diagram :

P(work | sport) = P(work n sport) / P(sport)

P(work n sport ) = 4

P(sport) = 6 + 4 = 10

Therefore,

P(work | sport) = P(work n sport) / P(sport)

P(work | sport) = 4 / 10

P(work | sport) = 2/5

Write the equation of an ellipse with vertices at (7, 0) and (-7, 0) and co-vertices at (0, 1) and (0, -1).

Irina-Kira [14]

Answer:

$\frac{(x)^{2}}{49}+\frac{(y)^{2}}{1}=1$

Step-by-step explanation:

In this problem we have a horizontal ellipse, because the major axis is the x-axis

The equation of a horizontal ellipse is equal to

$\frac{(x-h)^{2}}{a^{2}}+\frac{(y-k)^{2}}{b^{2}} =1$

where

(h,k) is the center of the ellipse

a and b are the respective vertices distances from center

we have

vertices at (7, 0) and (-7, 0)

co-vertices at (0, 1) and (0, -1)

The center is the origin (0.0) (The center is the midpoint of the vertices)

a=7

b=1

substitute

$\frac{(x-0)^{2}}{7^{2}}+\frac{(y-0)^{2}}{1^{2}}=1$

$\frac{(x)^{2}}{49}+\frac{(y)^{2}}{1}=1$

What is .25 written in its simplest fraction form? A. 2/5 B. 4/1 C. 1/4 D. 100/25

Furkat [3]

0.25 = 25/100

to simplify 25/100, divide 25 from both the numerator and denominator.

25/25 = 1

100/25 = 4

1/4 is the simplest form

C. 1/4 is your answer

hope this helps
