Write the equation 2x-3y=6in slope -intercept form​
Tcecarenko [31]

Answer:

y = 2/3 x -2

Step-by-step explanation:

Slope intercept form is y = mx+b where m is the slope and b is the y intercept

We need to solve for y

2x-3y = 6

Subtract 2x from each side

2x-2x-3y=-2x+6

-3y = -2x+6

Divide  by -3

-3y/-3 = -2/-3x+6 /-3

y = 2/3 x -2

The slope is 2/3 and the y intercept is -2

Study the solutions of three equations on the right. Then complete the statements below.
Hoochie [10]

Answer:

Part 1) There are two real solutions

Part 2) There is one real solution

Part 3) There are no real solutions

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

If the radicand is positive

(b^{2}-4ac) >0  ------> There are two real solutions

If the radicand is zero

(b^{2}-4ac) =0  ------> There is one real solution

If the radicand is negative

(b^{2}-4ac)  ------> There are no real solutions

therefore

Part 1) The radicand is positive

so

There are two real solutions

Part 2) The radicand is equal to zero

so

There is one real solution

Part 3) The radicand is negative

so

There are no real solutions

Point b lies on the segment ac . Find the length of the segment ac, if ab=7.8 cm, bc=25mm. How many different solutions can this
ladessa [460]

The length of the segment ac is 10.3 cm

<h3>How to determine the length ac?</h3>

The segments are given s:

ab = 7.8cm

bc = 25mm

Point b is located between points a and c.

So, we have:

ac = ab + bc

Substitute known values

ac = 7.8cm + 25mm

Express mm a  cm

ac = 7.8cm + 2.5cm

Evaluate the sum

ac = 10.3 cm

If the point b lies on segment ac, then there can be only one solution

Help the question is on the image.​
Phantasy [73]

Answer:

\boxed {tan\theta = \frac{2}{3}}

Step-by-step explanation:

<u>Let's derive a formula</u> :

⇒ Area (triangle) × 3 = Area (square)

⇒ 1/2(bh) × 3 = a²

∴ But a = h (shown in diagram)

⇒ 3/2(bh) = h²

⇒ <u>h = 3b/2</u>

<u>Now, taking tan θ</u> :

⇒ tan θ = b/h

⇒ tan θ = b/(3b/2)

⇒ tan θ = 2b/3b

⇒ tan θ = 2/3
