Drag and drop numbers into the equation to complete the equation of the line in slope-intercept form.
lara31 [8.8K]

Answer:

y = 4x - 15

Step-by-step explanation:

Find slope (m) using of the line that passes through (7, 13) and (4, 1).

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 13}{4 - 7} = \frac{-12}{-3} = 4

Find y-intercept (b) by substituting x = 4, y = 1, and m = 4 in y = mx + b.

Thus:

1 = (4)(4) + b

1 = 16 + b

Subtract 16 from each side

-15 = b

b = -15

substitute m = 4, and b = -15 in y = mx + b, to get the equation.

The equation of the line would be:

✅ y = 4x + (-15)

y = 4x - 15

|13x-4|+12 &lt; 56<br> Anybody know this cuz I do
Ronch [10]

Answer:

\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)

Step-by-step explanation:

<u>Inequalities with Absolute Value</u>

We must recall the following rule:

\text{If  }|M|0

Then:

-N

We have the following inequality:

|13x-4|+12 < 56

Subtracting 12:

|13x-4|< 56-12

|13x-4|< 44

Applying the rule:

-44

Adding 4:

-44+4

Operating:

-40

Dividing by 13:

\displaystyle -\frac{40}{13}

The solution expressed in interval form is:

\boxed{\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)}

How many square feet of outdoor carpet will we need for this hole​
tester [92]

Answer:

42 ft²

Step-by-step explanation:

First of all, who makes a hole in this shape?

Anyways,

You're going to want to split the figure into multiple different shapes. We already have a triangle, so I would split the remaining shape into a rectangle and trapezoid.

We can find the area of the triangle easily with the equation 1/2(bh)

So

1/2(2 · 3)

1/2(6)

3

So the triangle is 3 ft²

Now we can find the area of the rectangle.

The measurements will be 3 and 7. It's just base x height so it'll be 21 ft²

Finally the trapezoid.

Base 1: 6

Base 2: 3

Height: 4            (11-7)

Formula: 1/2h (b1 + b2)

1/2 · 4 (6+3)

2(9)

18 ft²

Now just add them together:

3+21+18=42

Hence, your answer is 42 ft²
