Answer:
3x - y + 7 = 0
Step-by-step explanation:
The given point is , ( -4 , -5) and the slope is 3. The point slope form is ,
=> y - y₁ = m( x - x₁)
=> y - (-5) = 3 { x - (-4) }
=> y +5 = 3( x + 4 )
=> y + 5 = 3x + 12
=> 3x - y + 12 - 5 = 0
=> 3x - y +7 = 0
Hence the equation of the line is 3x - y + 7 = 0 .In triangle ABC, m

Selena's dog completed an obstacle course that was 452 meters long. There were four parts to the course, all equal length. How long was each part of the course?
Answer:
113 meters long
Step-by-step explanation:
If each part is all equal in length, then each part is 1/4 the total length of the obstacle course. Therefore, each part of the course was 1/4(452)=113 meters long

Jim is twice as old as chin and four times as old as di.Their total ages altogether is equal to 84 years.Calculate jim's age
Answer:
48 years
Step-by-step explanation:
Let the ratio of their ages be
4:2:1
Sum up the numbers
4+2+1
= 7
Their total ages is 84
7/84
= 1/12
Therefore Jim age can be calculated as follows
= 12×4
= 48
Hence Jim is 48 years

Determine the solutions to each of the given quadratic equations.
(3x + 8)(3x + 8) = 0
(3x-8)(3x + 8) = 0
x(3x - 8) = 0
(3x-8)(3x - 8) = 0
= -8
Answer:
The answers to your questions are given below.
Step-by-step explanation:
1. (3x + 8)(3x + 8) = 0
3x + 8 = 0 or 3x + 8 = 0
3x = –8 or 3x = –8
x = –8/3 or –8/3
2. (3x – 8)(3x + 8) = 0
3x – 8 = 0 or 3x + 8 = 0
3x = 8 or 3x = –8
x = 8/3 or –8/3
3. x(3x – 8) = 0
x = 0 or 3x – 8 = 0
x = 0 or 3x = 8
x = 0 or 8/3
4. (3x – 8)(3x – 8) = 0
3x – 8 = 0 or 3x – 8 = 0
3x = 8 or 3x = 8
x = 8/3 or 8/3

The diameter of a dime is 17.91 millimeters, an the height is 1.35 millimeters. What is the volume of a dime? What is the volume of an oblique cylinder formed by stacking 50 dimes? Round your answers to the nearest hundredth.
Answer:
why does no one ever answer these questionsss?? it's always math to, like I'm just trying to pass my quick check, let alone the class. you know how much easier my life would be it's people just answered the questions. I'm gonna run away, to some Scottish Isle and live a quiet life, in a cozy home with the wind outside ruffling through the grass, and the tired tired sea crashing onto the shoreline. I'll only visit my family and friends once a year, but the rest of the time, I'll be there, in the quiet. eventually a young visitor will stumble through my b & b and he'll end up staying there for weeks, for reasons unknown to me. Then, we'll fall in love, to the quiet sound of the ocean outside. And it'll be just us, it'll be our place, our secret. we won't have to deal with the loud, crazy, hectic world. and it will be perfect. but for now I'm stuck trying to pass this math class.
Answer:
The volume of one dime is 340.11 mm3. The volume of 50 dimes is 17.005.32 mm3.

Answer:
a = 4
b = 2√3
Step-by-step explanation:
The side lengths of a 30°-60°-90° right triangle are in the ratio 1 : √3 : 2.
The shortest side in the given triangle is 2, so we can multiply by 2 to see the ratios are ...
2 : 2√3 : 4 = 2 : b : a
b = 2√3
a = 4

Answer:
20x² +19xy +3y²
Step-by-step explanation:
Use the distributive property.
(4x +3y)(5x +y)
= 4x(5x +y) +3y(5x +y)
= 20x² +4xy +15xy +3y²
Collect terms.
= 20x² +19xy +3y²
The slope of the line in the graph is 4. Fill in the y intercept. Choose the correct equation in the form y = mx + b The y intercept is: The equation is y =
Answer:
[tex]\rm\implies y = 4x + 3 [/tex]
Step-by-step explanation:
Given :-
The slope of the line in the graph is 4.And we need to find the equation of the line. On looking at the graph we see that , it cuts y axis at (0,3) .So the y Intercept of the equation is 3 .
Slope Intercept Form :-
[tex]\rm\implies y = mx + c[/tex]
Substituting the respective values :-
[tex]\rm\implies y = 4*x + 3 \\\\\rm\implies y = 4x + 3 [/tex]
Hence the equation of line is y = 4x + 3

Write the slope-intercept form of the equation of the line.
9514 1404 393
Answer:
y = x + 2
Step-by-step explanation:
We observe that the line crosses the y-axis at y=2, so the y-intercept is 2.
The line has a rise of 1 grid square for each run of 1 grid square to the right. The slope is the ratio of rise to run:
m = rise/run = 1/1 = 1
The slope and intercept can be put into the slope-intercept form:
y = mx + b . . . . . line with slope m and y-intercept b
y = 1x +2 . . . . . . line with slope 1 and y-intercept 2
y = x +2 . . . . . . . simplified
Two planes start from the same point and fly opposite directions. The first plane is flying 20 mph slower than the second plane in 2 h the planes are 540 mi apart. Find the rate of each plane
Answer:
This
Step-by-step explanation:
let x = rate of the slower plane (First plane!)
x+25 = rate of the faster plane (Second plane!)
The planes fly for 2 hours, where Distance = R*T
Distance between the planes = SUM of the distances.
R*T + R*T= 470 miles
2*x + 2*(x+25)=470
2x+2x + 50 = 470
4x+50=470
4x=420
x=105 mph First plane
x+25= 105+25=130 mph Second plane.
Answer:
4x+50=470
4x=420
x=105 mph First plane
x+25= 105+25=130 mph Second plane.

Answer:
The volume for a cone and pyramid are the same, V = 1/3 Bh where B is the area of the base.

To find:
The simplified form of the given expression.
Solution:
We have,
[tex]10n-\dfrac{1}{3}(9n-12)[/tex]
Using distributive property, it can be written as:
[tex]=10n-\dfrac{1}{3}(9n)-\dfrac{1}{3}(-12)[/tex]
