How do you classify a triangle by its sides and then by its angles ?

1 answer:

6 0

Well classifying by sides would either be equilateral, scalene or isosceles....and by angles it would be acute, right or obtuse

What is the slope of a line parallel to the line 5x + 3y = 15?

Elis [28]

The answer is B because first u subtract 3y from both sides and then subtract 15 from both and then divide both sides by -5 and u’ll have y=-5/3x+5 so -5/3 is the slope

Please help!!!! i don’t understand any of this and really need it.

astraxan [27]

Answer:

B) 3.2 mi

Step-by-step explanation:

1. The midpoints: midpoint formula = ((x₁ + x₂)/2, (y₁+ y₂)/2)

upper = ((6 + -4)/2, (8 + 0)/2) --> (1, 4)

lower = ((-8 + 2)/2, (3 + -5)/2) --> (-3, -1)

2. Distance: distance formula = √((x₁ - x₂)² + (y₁ - y₂)²)

√((1 + 3)² + (4 + 1)²) = √(16 + 25) = √41 ≈ 6.403... ≈ 6.4

3. Scale: 6.4 * 0.5 mi = 3.2 mi

Sort each equation according to whether it has one solution, infinitely many solutions, or no solution.

Sedaia [141]

Answer:

Equations with one solution: $-2(x-3) = 2x-6$

Equations with no solution:

$6(x+5) = 6x+11\\5(x-2) = 5x-7$

Equations with infinite many solutions: $-3(x-4) = -3x+12$

Step-by-step explanation:

We will solve each equation to see if it has one solution, no solution or infinite many solutions.

An equation where the value of variable can be found has one solution.

An equation with no solution has both sides different.

An equation with infinite solution will have both sides equal after solution(number)

So,

Equation 1:

5(x-2) = 5x-7

$5(x-2) = 5x-7\\5x-10 = 5x-7\\5x-5x = -7+10\\0 = 3$

As both sides are not equal, equation has no solution.

Equation 2:

$-3(x-4) = -3x+12\\-3x+12 = -3x+12\\-3x+3x = -12+12\\0=0\\$

As both sides are equal the equation has infinite many solutions.

Equation 3:

$-2(x-3) = 2x-6\\-2x+6 = 2x-6\\-2x-2x = -6-6\\-4x = -12\\\frac{-4x}{-4} = \frac{-12}{-4}\\x = 3$

As x=3, the equation has only one solution.

Equation 4:

$6(x+5) = 6x+11\\6x+30 = 6x+11\\6x-6x+30 = 11\\30 =11$

The equation has no solution.

Hence,

Equations with one solution: $-2(x-3) = 2x-6$

Equations with no solution:

$6(x+5) = 6x+11\\5(x-2) = 5x-7$

Equations with infinite many solutions: $-3(x-4) = -3x+12$

Lynn is making custom bricks. She combines 39 pounds of water and 48 pounds of brick dust in a mixing bucket. She spills 13 poun

artcher [175]

Answer:

A. 10 bricks

B. 4 pounds

Step-by-step explanation:

Water = 39 pounds

brick dust = 48 pounds

Total mixture = water + brick dust

= 39 + 48

= 87 pounds

She spills 13 pounds of the mixture while stirring

Remaining mixture = Total mixture - Spillage

= 87 pounds - 13 pounds

= 74 pounds

The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture

Number of bricks made = Remaining mixture / pounds per brick

= 74 pounds / 7 pounds

= 10 bricks remaining 4 pounds of the mixture

A. What is the greatest number of bricks Lynn can make?

10 bricks

B. How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest number of bricks?

4 pounds
