Answer:
y + 6 = (-8/5)(x - 1) in point-slope form
Step-by-step explanation:
Moving from the 1st point to the first, we see that x (the 'run') increases by 5 from -4 to 1, and y (the 'rise') decreases by 8. Thus, the slope of the line through these two points is m = rise / run = -8/5
Now we have two points on the line, plus the slope. Let's write out the point-slope formula for the equation of a straight line:
y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.
Here, using the point (1, -6), we obtain:
y + 6 = (-8/5)(x - 1) in point-slope form

a number times 12 is 72. which equation fits this statement?
Answer:
12x = 17
Step-by-step explanation:
So, this is a standard variable equation, so a number (I did x because I'm basic) times, multiplied by, whatever 12 = 72
So a number times 12 is 72 = 12x = 17
Now, if you wanted to actually solve this equation, you just have to do inverse operations:
17 ÷ 12 = 1.4167 (rounded)
So x = 1.4167
hope this helps:)

Which one is the correct one
Step-by-step explanation:
Sum of opposite angles are supplementary,
x + 60 + 3x = 180
4x + 60 = 180
4x = 180 - 60
4x = 120
x = 120 / 4
x = 30
In the diagram, the measure of angle 8 is 124º, and the measure of angle 2 is 84°
Answer:
whats the question?
Step-by-step explanation:
Answer:
Angle 7 = 56 °
Step-by-step explanation:
Angles 8 and 7 = 180 degrees
To get the degree of angle 7 subtract 124 from 180
180 - 124 = 56 degrees
Angle 7 = 56 degrees

Express as a trinomial.
(3x+8)(x + 6)
Answer:
multiply 3x by x then multiply 8 by 6 and get 48. since 8 and 6 are products of 48 they give a sum of 14 therefore your trinomial is
3x²+14x+48

The area of the triangle on a coordinate plane is 3 square units option (B) 3 square units is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have a triangle on a coordinate plane shown in the picture.
Triangle ABC has vertices A, B, and C at (0, 0), (3, 4), and (3, 2).
As we know, the area of the triangle is given by:
Area = (1/2)heightxbase length
Or
Area = (1/2)ADxBC
Area = (1/2)3x2
Area = (6/2)
Area = 3 square units
Thus, the area of the triangle on a coordinate plane is 3 square units option (B) 3 square units is correct.

prove that underroot 3-underroot 5 is irrational.
Please quickly I need this answer
Answer:
See Explanation
Step-by-step explanation:
Let us assume that [tex] \sqrt 3 - \sqrt 5[/tex] is a rational number.
So, it can be expressed in the form of [tex] \frac{p}{q} [/tex] where p and q are integers.
[tex]\therefore \sqrt 3 - \sqrt 5=\frac{p}{q}[/tex]
[tex]\therefore \sqrt 3 =\frac{p}{q}+ \sqrt 5[/tex]
[tex]\therefore \sqrt 3 =\frac{p+q\sqrt 5}{q}[/tex]
Squaring both sides:
[tex] (\sqrt 3) ^2 =\bigg(\frac{p+q\sqrt 5}{q}\bigg ) ^2 [/tex]
[tex]\therefore 3 =\frac{p^2 +5q^2 +2\sqrt 5 pq}{q^2 } [/tex]
[tex]\therefore 3q^2 ={p^2 +5q^2 +2\sqrt 5 pq}[/tex]
[tex]\therefore 0 = p^2 +5q^2 -3q^2 +2\sqrt 5 pq [/tex]
[tex]\therefore - 2\sqrt 5 pq=p^2 +2q^2 [/tex]
[tex]\therefore \sqrt 5 = \bigg (\frac{p^2 +2q^2}{-2pq} \bigg) [/tex]
[tex]\therefore \sqrt 5 = - \bigg(\frac{p^2 +2q^2}{2pq} \bigg) [/tex]
Since, p and q are integers so [tex] - \bigg(\frac{p^2 +2q^2}{2pq} \bigg) [/tex] is rational.
[tex]\therefore \sqrt 5 [/tex] is also rational.
But it contradicts the fact that [tex]\sqrt 5 [/tex] is irrational.
Hence, our assumption that [tex] \sqrt 3 - \sqrt 5[/tex] is rational is wrong.
[tex] \therefore \sqrt 3 - \sqrt 5[/tex] is irrational.

A circle is centered on point B. Points A, C and D lie on its circumference.
If ZABC measures 40°, what does ZADC measure?
Given:
A circle is centered on point B.
Points A, C and D lie on its circumference.
If [tex]m\angle ABC[/tex] measures 40°.
To find:
The [tex]m\angle ADC[/tex].
Solution:
Central angle theorem: According to this theorem, the central angle is equal to the twice of inscribed angle on the same intercepted arc.
In the given figure [tex]\angle ABC[/tex] is the central angle and [tex]m\angle ADC[/tex] is the inscribed angle on the same arc AC.
Using central angle theorem, we get
[tex]m\angle ABC=2m\angle ADC[/tex]
[tex]40^\circ=2m\angle ADC[/tex]
[tex]\dfrac{40^\circ}{2}=m\angle ADC[/tex]
[tex]20^\circ=m\angle ADC[/tex]
Therefore, the measure of angle ADC is 20°.
please help I have no clue how to do this
Step-by-step explanation:
It's a question of trigonometry.
You need to remember that tangent (tan) stands for Perpendicular / Base.
So, tan P = QR / PR
By Pythagoras Theorem,
34² = 30² + x²
x² = 34² - 30²
x² = 1156 - 900
x² = 256
x = 16
Now, placing the values,
tan P = 30 / 16
tan P = 1.875

Answer:
x=14
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
2(x - 9) = 10
2x - 18 = 10
add 18 o each side of the equation:
2x = 28
divide both sides by 2:
x = 14
