Complete the table of values for this absolute value function. Then use the drawing tool(s) to graph the function. F(x)-2|x+1|-1

Answer:

x = 146°

Step-by-step explanation:

(all angles in a triangle add up to 180°)

180 - 115 - 31 = 34

(supplmentary angle)

180 - 34 = 146°

Answer:

acute angle

Step-by-step explanation:

acute = angles that are less than 90⁰

The triangles which have three angles that measure less than 90° are:

acute triangle, equilateral triangle

"An acute triangle is a triangle with three acute angles that means each angle measures less than 90°."

"An equilateral triangle is a triangle where all sides and angles are equal. Each angle of an equilateral triangle measures 60°. "

"A right triangle is a triangle where one of the angle measures 90°. "

"A triangle that has two sides of equal length is called as an isosceles triangle. Also, two angles that are opposite to equal sides are always equal and measures less than 90°. "

For given question,

As one of the angle of right triangle measures 90°, it is not a required triangle.

Also, for isosceles triangle, although two equal angles measure less than 90°, the third angle can be 90°. So, an isosceles triangle is not a required triangle.

Therefore, the triangles that have three angles that measure less than 90° are:

1) acute triangle

2) equilateral triangle

Answer:

Step-by-step explanation:

2 1/2* -4 3/5=

5/2*-23/5

-23/2 or -11 1/2

Answer:

m∠X= 22°

Step-by-step explanation:

In ΔVWX:

m∠V=(7x−1) ∘

m∠W=(4x+16) ∘ ,

m∠X=(3x−17) ∘ . Find M∠X.

Step 1

We find the variable x

The sum of angles in a triangle is 180°

Hence,

ΔVWX = m∠V + m∠W +m∠X

180° = (7x - 1)° + (4x + 16)° + (3x - 17)°

180° = 7x - 1 + 4x + 16 + 3x - 17

180° = 7x + 4x + 3x - 1 + 16 - 17

180° = 14x -2

Collect like terms

180° + 2 = 14x

182° = 14x

x = 182°/14

x = 13°

Step 2

We find m∠X

m∠X = (3x−17) ∘

x = 13

m∠X = (3 × 13 − 17)°

m∠X = (39 − 17)°

m∠X = 22°

its an obtuse angle so each equation should equal 180

Hint: (9y+7) = 180 and (2y+98) = 180

Answer:

3 is a whole number but 2x is 2 multiplied by a variable

Answer:

Ranger's simplified expression was 0.1x + 18.2

The correct answer is the first option.

Step-by-step explanation:

To simplify the given expression

3(2.7x + 5) – 2(4x – 1.6)

First, we will open the brackets by distributing 3 and 2, that is

(3×2.7x) + (3×5) -(2×4x) -(2×-1.6)

Now, we will get

8.1x + 15 - 8x +3.2

Now, collect like terms,

8.1x - 8x + 15 + 3.2

Then, we will get

0.1x + 18.2.

Hence, Ranger's simplified expression was 0.1x + 18.2.

The correct answer is the first option.

Answer:

16cm

Step-by-step explanation:

Step one:

given

the scale of the map

[tex]2 cm: 8 km.[/tex]

Step two:

so if a scale of 2 cm represents 8 km.

       then let xcm be 64km

cross multiply we have

[tex]x*8= 64*2[/tex]

8x= 128

divide both sides by 8

[tex]x= 128/8\\\\x=16cm[/tex]

The map distance is 16cm

Answer:

y = 1/3 x + 2

Step-by-step explanation:

We see points (-3, 1) and (3, 3).

We also see point (0, 2), the y-intercept.

To go from (-3, 1) to (3, 3), go up 2 and right 6.

slope = m = rise/run = 2/6 = 1/3

y = mx + b

y = 1/3 x + 2

Answer: 33 groups

Step-by-step explanation:

Number of people that signed for help = 130 people

Number of people that can join a group = 4.

Number of groups that will be formed will be:

= Number of people that signed for help / Number of people that can join a group

= 130/4

= 32.5

= 33 groups

Since there'll be a remainder of 2 people, they will form a new group making 33 groups.
