A line through (-4,6) with slope-3/2 and graph

Mathematics
1 answer:
marin [14]3 years ago
7 0

Answer:

y = -\frac{3}{2}x

Step-by-step explanation:

Given

Passes through: (-4,6)

Slope: -3/2

Required

The equation and graph

The equation is calculated as:

y = m(x - x_1) + y_1

Where

m = -\frac{3}{2}

(x_1,y_1) = (-4,6)

So, we have:

y = -\frac{3}{2}(x --4) + 6

y = -\frac{3}{2}(x +4) + 6

Open bracket

y = -\frac{3}{2}x -6 + 6

y = -\frac{3}{2}x

See attachment for graph

6. Find the value of x in the triangle below.
Kobotan [32]

Answer:

The value of x is 21.

Step-by-step explanation:

Since this is a right angle triangle, you can apply Pythagoras theorem, side² + side² = hypo² :

(x + 3)² + 10² = (x + 5)²

x² + 6x + 9 + 100 = x² + 10x + 25

x² + 6x + 109 - x² - 10x - 25 = 0

-4x + 84 = 0

-4x = -84

4x = 84

x = 84 ÷ 4

x = 21 units

The cost of a car rental is ​$30 per day plus 18c per mile. You are on a daily budget of ​$75. Write and solve an inequality to
Tanzania [10]

Answer:

2. 5 miles

Step-by-step explanation:

Given that:

Rental cost = $30

Cost per mile driven = 18 cent

Daily budget = $75

Greatest distance you can drive each day while staying within budget :

Rental cost + (cost per mile driven * distance) ≤ daily budget

$30 + 18d ≤ $75

18d ≤ 75 - 30

18d ≤ 45

d ≤ 45 / 18

d ≤ 2.5

Greatest distance you can drive each day while staying within budget is 2.5 miles.
