We can use the points (2, -2) and (4, -1) to solve.

Slope formula: y2-y1/x2-x1

= -1-2/4-(-2)

= -3/6

= -1/2

Point slope form: y - y1 = m(x - x1)

y - 2 = -1/2(x + 2)

Solve for y-intercept.

-2 = -1/2(2)  + b

-2 = -1 + b

-2 + 1 = -1 + 1 + b

-1 = b

Slope Intercept Form: y = mx + b

y = -1/2x - 1

Drag each number to show whether or not it is a solution to the inequality shown.
Pani-rosa [81]

Answer:

The numbers that work are: -15, 5, 3.5, and 4 3/4

Step-by-step explanation:

Subtract 5 from both sides of the equation. Which will give you 15≥3x. Then you divide both sides by 3 which will give you 5≥x.

20≥5+3x

<u>-5        -5</u>

15≥ 3x

<u>÷ 3      ÷ 3</u>

5 ≥ x

Write a conditional statement that correctly describes each venn diagram in the space provided?
MakcuM [25]
Remember that a conditional statement (p→q) is an if-then in which the first part, p, is the hypothesis and the second part, q, is the conclusion. 

1. Here the set m<span>∠A=40° is a subset of the set Acute Angles, so </span>m∠A=40° is the hypothesis and Acute Angles is the conclusion. 
In other words:
m∠A=40°→∠A is an Acute Angle 
if m∠A=40°, then ∠A is an Acute Angle

We can conclude that the conditional statement that describes the Venn diagram is: if m∠A=40°, then ∠A is an Acute Angle

2. Just like before, the set 2x=4 is a subset of the set x=2; therefore, 2x=4 is the hypothesis and x=2 is the conclusion.
In other words:
2x=4→x=2
if 2x=4, then x=2

We can conclude that the conditional statement that describes the Venn diagram is: if 2x=4, then x=2

8. Teo makes a necklace of x wooden beads at $0.50
VARVARA [1.3K]

Answer:

0.5x + 7.5 / (x + 6)

Step-by-step explanation:

Let x be the number of wooden beads

wooden bead = $0.50 each

glass bead = $1.25 each

since average cost of bead = (cost of wooden bead + cost of glass bead)/ total number of beads

equation is (0.5x + (6*1.25))/(x + 6)

The model equation is therefore 0.5x + 7.5 / (x + 6)
