Answer:
y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = S (- 9, 8) and (x₂, y₂ ) = G (- 3, 3)
m = [tex]\frac{3-8}{-3+9}[/tex] = - [tex]\frac{5}{6}[/tex] , then
y = - [tex]\frac{5}{6}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 3 ), then
3 = [tex]\frac{5}{2}[/tex] + c ⇒ c = 3 - [tex]\frac{5}{2}[/tex] = [tex]\frac{1}{2}[/tex]
y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex] ← equation of line

What is an equation of the line that passes through the points (0, -3)(0,−3) and (-5, 3)(−5,3)?
Answer:
y = 6/5 x -3
Step-by-step explanation:
Standard equation of a line is expressed as;
y = mx+b
Slope m = y2-y1/x2-x1
Given the coordinates (0, -3)and (-5, 3)
Slope m = 3-(-3)/-5-0
Slope m = 6/5
Since the line cuts the y axis at y = -3, hence b = -3
GEt the required equation;
Recall that y = mx+b
y = 6/5 x + (-3)
y = 6/5 x -3
This gives the required equation

7 video games
Step-by-step explanation:
25.50x ≤ 200
S would be the number of video games
25.50x ≤ 200 Divide both sides by 25.50 to isolate x
x ≤ 7.8...
Since he can't buy a fraction of a game, round 7.8 down to get 7 video games
If p(x) = x 3 + x 2+ root 5 x + root 5 , then find p( – 5 )
Answer:
-100-4√5
Step-by-step explanation:
Given the polynomial expression
p(x) = x³+x²+√5x + √5
p(-5) = (-5)³+(-5)² + √5(-5) + √5
p(-5) = -125 + 25 -5√5 + √5
p(-5) = -100-4√5
This gives the required answer

Is 21 3/7 a rational or an irrational number?
Answer:
Rational
Step-by-step explanation:
This number is rational because it can be expressed as a ratio between two numbers.
Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 20 10. 5
Given:
Consider the given terms of the sequence are:
20, 10, 5, ...
To find:
The type of sequence (arithmetic or geometric) and the common difference / ratio in simplest form.
Solution:
We have,
20, 10, 5, ...
Difference between consecutive terms are:
[tex]10-20=-10[/tex]
[tex]5-10=-5[/tex]
Since [tex]-10\neq -5[/tex], therefore the given sequence has no common difference, it means the given sequence is not arithmetic.
Ratio between consecutive terms are:
[tex]\dfrac{10}{20}=\dfrac{1}{2}[/tex]
[tex]\dfrac{5}{10}=\dfrac{1}{2}[/tex]
The given sequence has a common ratio [tex]\dfrac{1}{2}[/tex], it means the given sequence is a geometric sequence.
Therefore, the given sequence is a geometric sequence with common ratio [tex]\dfrac{1}{2}[/tex] it is also written as 0.5.

Can somebody help me with the geometry equation.
Answer:
[tex]m\widehat{VU}=120^{\circ}[/tex]
Step-by-step explanation:
The angle [tex]\angle TUV[/tex] forms arc [tex]\widehat{TV}[/tex]. The measure of this arc is twice the measure of angle [tex]\angle TUV[/tex], since [tex]U[/tex] is a point on the circle. Since [tex]\overline{TU}[/tex] forms an arc [tex]\widehat{TU}[/tex], we can set up the following equation:
[tex]\widehat{TV}+\widehat{VU}=\widehat{TU}[/tex].
Since arc TU represents half of a circle and there are 360 degrees in a circle, we can substitute the following values and solve for the measure of arc VU:
[tex]\\2\cdot 30^{\circ}+\widehat{VU}=180^{\circ},\\60^{\circ}+\widehat{VU}=180^{\circ},\\m\widehat{VU}=\boxed{120^{\circ}}[/tex]

x
Answer:
x = 136°
Step-by-step explanation:
We can use a theorem to help us.
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
For exterior angle x, the remote interior angles are z and <CBD.
From the theorem, we get this equation.
x = z + m<CBD
We know z = 52°.
We need to find m<CBD.
Angles CBD and y are a linear pair. They are supplementary, so the sum of their measures is 180°. We are given y = 96°.
m<CBD + y = 180°
m<CBD + 96° = 180°
m<CBD = 84°
x = z + m<CBD
x = 52° + 84°
x = 136°
Answer:
x = 136°
Step-by-step explanation:
∠ABD = y = 96°, ∠ABD + ∠DBC must be equal to 180° because they form a straight angle.
[tex]y + B = 180\\96 + B = 180\\B = 180 - 96 = 84[/tex]
∠BDC = z = 52° and ∠DBC = B = 84.
Angles ∠BDC, ∠DBC, and ∠BCD must have a sum of 180° because the sum of the interior angles in a triangle is 180°.
[tex]180=(180 - y) + 52 + C\\180=(180 - 96) + 52 + C\\180 - (52 + 84) = C\\C = 44[/tex]
The interior angle at C is 44. Line DCE forms a straight line, therefore having an angle of 180°. To find x, the sum of x and interior angle C is 180°.
[tex]180 = C + x\\180 = 44 + x\\x = 180-44\\x = 136\\[/tex]
Angle ∠BCE = x = 136.

Answer:
a) adjacent angles, complementary angles
b) vertical angles, congruent angles
c) supplementary angles, adjacent angles
d) supplementary angles, adjacent angles
Step-by-step explanation:
Adjacent angles are angles that share a common vertex, ( usually angles that are right next to each other )
Complementary angles are angles that form a 90 degree angle ( right angle )
Supplementary angles are angles that form a straight line
Vertical angles are angles that are vertically aligned with each other ( vertical angles are congruent )

Answer:
7
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
let the third side be x , then
x² + (4[tex]\sqrt{2}[/tex] )² = 9²
x² + 32 = 81 ( subtract 32 from both sides )
x² = 49 ( take the square root of both sides )
x = [tex]\sqrt{49}[/tex] = 7
Then the third side is 7
