Question 2. In the given figure find the value of x in each angle of a triangle.

Very very important Plz.​

Answer:

[tex](2,1)[/tex]

Step-by-step explanation:

You can just use the formula [tex]x=-\frac{b}{2a}[/tex]:

[tex]y=ax^2+bx+c[/tex]

[tex]y=\frac{1}{2}x^2-2x+3[/tex]

[tex]x=-\frac{-2}{2(\frac{1}{2})}=\frac{2}{1}=2[/tex]

[tex]y=\frac{1}{2}(2)^2-2(2)+3=\frac{1}{2}(4)-4+3=2-4+3=-2+3=1[/tex]

Therefore, the minimum value of the equation is [tex](2,1)[/tex]

Answer:

Number 4 is -5 I believe

Step-by-step explanation:

[tex] \frac{ {a} + 4 }{ {a}^{2} + 7a + 10} \times \frac{ {a}^{2} + 6a + 5}{ {a}^{2} + 5a + 4 } \\ = \frac{ {a} + 4 }{ (a + 2)(a + 5)} \times \frac{(a + 5)(a + 1)}{(a + 4)(a + 1)} \\ = \frac{1}{a + 2}\\\\ \frac{9m-4}{8}+\frac{3m+8}{8} \\=\frac{12m+4}{8}\\=\frac{3m-1}{2}\\\\\frac{4{x}^{2}}{2x-7}-\frac{49}{2x-7}\\=\frac{4{x}^{2}-49}{2x-7}\\=\frac{(2x-7)(2x+7)}{2x-7}\\=(2x+7)[/tex]

Answer:

2(3x+7) -15

Step-by-step explanation:

Let x = unknown number

7 is added to 3 times a number

3x+7

Multiply the sum by 2

2(3x+7)

Subtract 15

2(3x+7) -15

Answer:

Let the required number be " x "

Now, 7 is added to 3 times a number : (3x + 7)

Next, the sum is multiplied by 2 : 2(3x + 7)

And then, 15 is substracted from it : 2(3x + 7) - 15

x² = 12² + 10²

x² = 144 + 100

x² = 244

x = 15,6m✔

x² = 12² + 10²

x² = (12 × 12) + (10 × 10)

x² = 144 + 100

x² = 244

x = √244

x = 15,6 m

Answer:

61

Step-by-step explanation:

(-7x)+5

Let x = -8

-7*(-8) +5

56+5

61

Answer:

61

Step-by-step explanation:

Here you are just substituting for x.

Since x = -8  we just plug that into the expression.

-7x + 5

-7(-8) + 5

56 + 5

= 61

Answer:

3 ÷ 8

Step-by-step explanation:

1. A fraction has two parts: a numerator and a denominator. The numerator is the dividend (the number that is to be divided by the divisor), and the denominator is the divisor (the number that is divided into the dividend).

2. Given the information above, we know that 3 is the numerator, and 8 is the denominator. This means 3 ÷ 8 = 3/8.

[tex]slope = y2 - y1 \div x2 - x1[/tex]

[tex]6 - 1 \div - 2 - 3[/tex]

[tex]5 \div - 5 [/tex]

[tex] - 1[/tex]

[tex]y = mx + c[/tex]

[tex]1 = - 1 \times 3 + c[/tex]

[tex]1 = - 3 + c[/tex]

[tex]1 + 3 = c[/tex]

[tex]c = 4[/tex]

[tex]y = - 1x + 4[/tex]

[tex]y = - x + 4[/tex]

Step-by-step explanation:

Answer:

mB = 113 degrees

Step-by-step explanation:

180 - 67 = 113

Answer:

mB=113

Step-by-step explanation:

mA=67

Triangles are 180 with all angles added together.

To find mB subtract mA with 180.

180 - 67 = 113

mB=113

Answer:

15.3%

Step-by-step explanation:

60x.05 = 3 boys

130x.20 = 26 girls

3+26 = 29 students

60+130 = 190 total students

(29/190)*100 = 15.3%

Answer:

Step-by-step explanation:

Use the given rule and find the coordinates as follows:

The points are plotted, see the attached.

Answer:

Before I start, wouldn't you go right three times since it's x + 3 not x - 3. Id.k maybe I'm just slow.

Anyways, take your current points which are A(-2,-4), B(0,0), and C(1,-3) and apply the new mapping rule to them. For example: (-2 + 3, -4 -5), and that will give you A' (1,-9). If you do the same to the other two, you'd have B' (3,-5) and C' (4,-8).

I graphed A, B, C, and A', B', C' above for you.⤴⤴

Hope the graph makes sense, good luck :)

Answer:

cccccccccccccccccccccccc

I think the answer is 32 maybe

The area of the shape

= (3×2)+(3×2)+(10×1)

= 6 + 6 +10

= 22

Answer:

D

Step-by-step explanation:

The x-axis is the horizontal line. Therefore D is directly on the line, making it on the x axis.

Answer:

r = 32 1/3

Step-by-step explanation:

5/(r-9) = 8/(r+5)

cross multiply:

5 x (r + 5) = 8 x ( r - 9)

5r + 25 = 8r - 72

Add 72 to both sides:

5r + 97 = 8r

Subtract 5r from both sides

97 = 3r

Divide both sides by 3

r = 32 1/3

-Chetan K

Answer:

r = 32 1/3 or 97/3

Step-by-step explanation:

Step 1: Cross-multiply.

Step 2: Subtract 8r from both sides.

Step 3: Subtract 25 from both sides.

Step 4: Divide both sides by -3.

Therefore, r = 32 1/3 or 97/3.

Answer:

36.25 units

Step-by-step explanation:

Hi there!

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where two endpoints are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points ​(19​,−8​) and ​(−14​,−23​):

[tex]d=\sqrt{(19-(-14))^2+(-8-(-23))^2}\\d=\sqrt{(19+14)^2+(-8+23)^2}\\d=\sqrt{(33)^2+(15)^2}\\d=\sqrt{1089+225}\\d=\sqrt{1314}\\d=36.25[/tex]

Therefore, the distance between the points is approximately 36.25 units.

I hope this helps!

Answer:36.25

Step-by-step explanation:distance between (x1, y1) and (x2,y2) is square root of (x2-x1)^2 + (y2-y1)^2. think of graph the distance between two points is the hypotenuse of a right angle triangle where the height is the difference of y and base is the difference of x

= square root of (19+14)^2 +(-23+8)^2= 36.25

Answer:

height = 5 m

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

V = Ah ( A is area of base and h the height )

Here V = 120 and A = 24 , then

24h = 120 ( divide both sides by 24 )

h = 5

The height of the crate is 5 m
