Answer:

( -3.5, 1.5 )

Step-by-step explanation:

You have to use slope-intercept form to solve this; y=mx+b

m= 7/2 (x,y) = (-3,3)

3 = 7/2 (-3) + b

3 = 10.5 + b

b = -7.5

y = 7/2 - 7.5

The coordinates would be ( -3.5, 1.5 )

MA_775_DIABLO [31]

<h3>Given : </h3>

Base of triangle = 8 cm
Height of triangle = 4 cm

$\\$

Area of triangle = ?

$\\$

<h3>Solution :</h3>

As, we have :

Base of triangle, b = 8 cm
Height of triangle, h = 4 cm

$\\$

So, to find area of triangle we have a formula :

$\large \underline{\boxed{\bf{Area_{(triangle)} = \dfrac{1}{2} \times b \times h}}}$

$\tt : \implies Area = \dfrac{1}{2} \times 8 \: cm \times 4 \: cm$

$\tt : \implies Area = \dfrac{1}{2} \times 32 \: cm^2$

$\tt : \implies Area = \cancel{\dfrac{32}{2}} \: cm^2$

$\tt : \implies Area = 16 \: cm^2$

$\\$

Hence, area of given triangle is 16 cm².

GET BRAINLIEST FOR THE CORRECT ANSWER AND EXPLANATION!

Tresset [83]

Interpreting the inequality, it is found that the correct option is given by F.

------------------

The first equation is of the line.
The equal sign is present in the inequality, which means that the line is not dashed, which removes option G.

In standard form, the equation of the line is:

$x + 2y = 6$

$2y = 6 - x$

$y = -0.5x + 2$

Thus it is a decreasing line, which removes options J.

We are interested in the region on the plane below the line, that is, less than the line, which removes option H.

------------------

As for the second equation, the normalized equation is:

$3x^2 + 3y^2 = 12$

$3(x^2 + y^2) = 12$

$x^2 + y^2 = 4$

Thus, a circle centered at the origin and with radius 2.
Now, we have to check if the line $x + 2y - 6 = 0$ , with coefficients $a = 1, b = 2, c = -6$ , intersects the circle, of centre $x = 0, y = 0$
First, we find the following distance:

$d = \sqrt{\frac{|ax + by + c|}{a^2 + b^2}}$

Considering the coefficients of the line and the center of the circle.

$d = \sqrt{\frac{|1(0) + 2(0) - 6|}{1^2 + 2^2}} = \sqrt{\frac{6}{5}} = 1.1$

This distance is less than the radius, thus, the line intersects the circle, which removes option K, and states that the correct option is given by F.

Given 2 events a and b, and that p(a)=0.30, p(b)=0.45, p(a u b)=0.60. find the probability p(a∩b).

pickupchik [31]

P(a U b) = p(a) + p(b) - p(a ∩ b)

<=>

p(a ∩ b) = p(a) + p(b) - p(a U b)

I let you do the maths :)

What is the solution to 0.4(12 – 3x) = 0.3(12x – 16)?

Answer:

x = 2

General Formulas and Concepts:

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

0.4(12 - 3x) = 0.3(12x - 16)

<u>Step 2: Solve for </u><em><u>x</u></em>

Distribute: 4.8 - 1.2x = 3.6x - 4.8
Add 1.2x on both sides: 4.8 = 4.8x - 4.8
Add 4.8 on both sides: 9.6 = 4.8x
Divide 4.8 on both sides: 2 = x
Rewrite: x = 2
