What is the equation of the line on the graph? Write your answer in slope-intercept form. (y = mx + b)
Don't forget to simply if you can!
Answer:
y= ⅔x -2
Step-by-step explanation:
slope-intercept form
y= mx +b, where m is the slope and b is the y-intercept.
Two given coordinates: (-3, -4) and (6, 2)
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
Slope
[tex] = \frac{2 - ( - 4)}{6 - ( - 3)} [/tex]
[tex] = \frac{2 + 4}{6 + 3} [/tex]
[tex] = \frac{6}{9} [/tex]
[tex] = \frac{2}{3} [/tex]
Substitute m= ⅔ into the equation:
y= ⅔x +b
From the graph, the y- intercept is -2 since the line cuts through the x-axis at (0, -2).
Alternatively, we can also substitute a pair of coordinates into the equation to find the value of b.
When x= 6, y= 2,
[tex]2 = \frac{2}{3} (6) + b[/tex]
2= 4 +b
b= 2 -4
b= -2
Thus the equation of the line is y= ⅔x -2.

Z is the centroid of AUVW. U X Z W Y What is UY if UZ = 8? Ο Α. 4 B. 8 O C. 6 O D. 12
Help Please!!
Answer:
D
Step-by-step explanation:
The distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint, that is
ZY = [tex]\frac{1}{2}[/tex] UZ = [tex]\frac{1}{2}[/tex] × 8 = 4
Then
UY = UZ + ZY = 8 + 4 = 12 → D

Find the values of m for which the equation
x^2 +2mx + 9 = 0 has no real roots
Answer:
Interval notation for m: (-3,3)
Inequality notation: -3<m<3
In words: Anything between -3 and 3 without including either -3 or 3.
Step-by-step explanation:
If we want no real roots then b^2-4ac must be less than 0.
a=1
b=2m
c=9
These values were found by comparing your equation to ax^2+bx+c=0.
b^2-4ac<0 is what we are trying to satisfy
(2m)^2-4(1)(9)<0
4m^2-36<0
Divide both sides by 4:
m^2-9<0
Add 9 on both sides:
m^2<9
m^2<9 when m<3 and m>-3.
Interval notation (-3,3).

Side AB of a parallelogram ABCD is produced upto point E. If m<CBE = 35°, find m<ADC.
Answer:
The measure of ∠ADC = 145°
Step-by-step explanation:
ABCD is a Parallelogram.
AB is produced to E .
∠CBE = 35°
We know that
∠ABC + <CBE = 180[tex]\degree[/tex]
Since , they are linear pair
➜ ∠ABC + 35° = 180°
➜ ∠ABC = 180°-35°
➜ ∠ABC = 145°
We know that
In a Parallelogram, Opposite angles are equal.
➜ The opposite angle of ∠ABC = ∠ADC
➜ ∠ADC = 145°
Therefore, The measure of ∠ADC = 145°

Leonardo da Vinci's portrait the Mona Lisa is
2 feet 6 inches long and 1 ft 9 inches wide.
Janelle has a refrigerator magnet of the
painting that is 3.5 cm wide. What is the
length of the magnet?
Answer:
the length of the magnet is 5cm
Step-by-step explanation:
first convert the feet into inches: 2ft 6in=30in, 1ft 9in=21in
then convert inches into centimeters (times by 2.5): 30*2.5=75cm 21*2.5=52.5
then divide 52.5 by 3.5 to get a proportion: 52.5/3.5=15
then divide 75 by 15: 75/15=5cm

triangles one and two are both isosceles meaning they each have two equal sides they each have a 30-degree angle explain why these triangles do not have to be similar to each other
Answer:
See below for answers
Step-by-step explanation:
These triangle do not have to be similar to each other because the 30° angles may not be located in the same place.
For example, place one 30° at the vertex of the triangle which is located where the two equal legs of the isosceles triangle are joined. The triangle angles measure are 30°, 75°, and 75°.
But if the 30° angle is one angle at the base of the isosceles triangle, then the angles measure are 30°, 30°, 120°.

y=-2(x+9)(x+3)
Answer:
max at (- 6, 18 )
Step-by-step explanation:
Given the equation of a parabola in intercept form
y = a(x + c)(x + d)
• If a > 0 then min vertex
• If a < 0 then max vertex
y = - 2(x + 9)(x + 3) ← is in intercept form
with a = - 2 < 0 then max vertex
y = - 2(x + 9)(x + 3) ← expand factors using FOIL
= - 2(x² + 12x + 27) ← distribute parenthesis by - 2
y = - 2x² - 24x - 54 ← in standard form
with a = - 2 and b = - 24
The x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex] = - [tex]\frac{-24}{-4}[/tex] = - 6
Substitute x = - 6 into the equation and evaluate for y
y = - 2(- 6 + 9)(- 6 + 3) = - 2(3)(- 3) = 18
vertex = (- 6, 18 ) and is a max
Determine the value of x.
Answer:
x = 16
Step-by-step explanation:

3x = 48 ( divide both sides by 3 )
x = 16

140 grams of almonds cost $3.5. Mechael needs almonds for the dish she is preparing. How much she has to pay for 500 grams of almonds cost?
Answer:
$12.5
Step-by-step explanation:
140 divided by 7 is 20, since 20 is a factor of 500, it will make it easier. Since we divided the 140 grams by 7, we also have to divide the $3.5 by 7, which will get you$0.5. 20 times 25 is 500, so you will also time the $0.5 by 25 which will get you $12.5

Answer:
x < 4
Step-by-step explanation:

x < 4
Answer:
x < 4.
Step-by-step explanation:
3x - 3 < 9
Add 3 to both sides:
3x < 9 + 3
3x < 12
Divide both sides by 3:
x < 4.
