can the following side lengths form a triangle?

Answers

Answer:

  no

Step-by-step explanation:

The triangle inequality requires the sum of the shorter two sides exceed the length of the longest one. Here, we have ...

  10 +12 = 22 . . . . does not exceed 22

The lengths will not form a triangle.

_____

Additional comment

Some authors write the triangle inequality as ...

  a +b ≥ c

If this is the one your curriculum author uses, then these side lengths will form a triangle.

Use the Binomial Theorem to expand the binomial
(d + 5b)3

Answers

Answer:

[tex]\displaystyle{(d+5b)^3 = d^3 + 15bd^2 + 75b^2d + 125b^3}[/tex]

Step-by-step explanation:

The Binomial Theorem states that:

[tex]\displaystyle{(x+y)^n = \binom{n}{0}x^ny^0 + \binom{n}{1}x^{n-1}y^1+\binom{n}{2}x^{n-2}y^2 + \dots + \binom{n}{n}x^{n-n}y^n}[/tex]

Note that:

[tex]\displaystyle{_n C _r = \binom{n}{r} = \dfrac{_n P _r}{r!} = \dfrac{n!}{(n-r)!r!}}[/tex]

Therefore, first, we will write the expansion:

[tex]\displaystyle{(d+5b)^3 = \binom{3}{0}d^3(5b)^0 + \binom{3}{1}d^2(5b)^1+\binom{3}{2}d^1(5b)^2 + \binom{3}{3}d^0(5b)^3}[/tex]

Evaluate each terms:

[tex]\displaystyle{(d+5b)^3=\dfrac{3!}{3!0!}d^3 + \dfrac{3!}{2!1!}d^25b+\dfrac{3!}{1!2!}25b^2d + \dfrac{3!}{0!3!}125b^3}\\\\\displaystyle{(d+5b)^3 = d^3 + 15bd^2 + 75b^2d + 125b^3}[/tex]

Henceforth, [tex]\displaystyle{(d+5b)^3 = d^3 + 15bd^2 + 75b^2d + 125b^3}[/tex] is the expansion.

Answer:

     y = 2

Step-by-step explanation: Given in the question,

a co-ordinate = (-2,2)

x = -2

y = 2

Equation of the straight line

y = mx + c

here m = gradient of the line  

c = y - intercept

we know that gradient of the horizontal line = 0

plug value in the equation above

y = (0)x + 2

y = 2

Look at the graph shown:

A coordinate plane is shown. A line passes through the y-axis at -1 and through the point 1 comma 2.
Which equation best represents the line? (4 points)

y = 1 over 3.x − 1
y = 3x − 1
y = 3x + 1

Answers

Answer:

y = 3x - 1

Explanation:

1)

passes y-axis means x will be 0,

when x = 0,

y = 3x − 1

y = 3(0)-1

y = -1 ................so matches with option 1.

2)

Here given in second option passes through ( 1 , 2 )

if x = 1

y = 3x − 1

y = 3(1) − 1

y = 2 ..........................so matches with option 2.

Therefore equation: y = 3x - 1 represents the current following.

Answer:

y = 3x - 1

Step-by-step explanation:

y=s when x=3, find when x=12

Answers

Answer:

y = s * 4

Step-by-step explanation:

You multiplied 4 to 3 to obtain 12:

x = 3 ; x = 3 * 4 ; x = 12

Therefore, if you multiply 4 to x, you must do the same to the other:

y = s

y = s * 4 is your answer.

This graph represents a linear function.

Which equation is represented by this graph?

Answers

Answer:

Answer is A

Step-by-step explanation:

» Consider two points plotted on the line;

(3, 0) and (0, -2)

» General equation of a line has an expression in format of;

[tex]{ \rm{y = mx + c}}[/tex]

m is the slopec is the y-intercept

» Finding the slope [m] :

[tex]{ \rm{slope = \frac{y_{2} - y _{1}}{x _{2} - x _{1} } }} \\ [/tex]

• But remember from the points or coordinates we fetched out of the graph;

[tex] { \tt{y_{2} = - 2}} \: \mid \: { \tt{y_{1} = 0}} \\ { \tt{x_{2} =0 }} \: \mid \: { \tt{x_{1} = 3}}[/tex]

Therefore, lets feed in the formular:

[tex]{ \tt{m = \frac{ {}^{ - } 2 - 0}{0 - 3} = \frac{ - 2}{ - 3} }} \\ \\ { \boxed{ \tt{m = \frac{2}{3} }}}[/tex]

» Finding y-intercept [c] :

REMEMBER: y = mx + c

• Consider point (0, -2)

[tex]{ \tt{y = mx + c}} \\ { \tt{ - 2 = ( \frac{2}{3} \times 0) + c}} \\ \\ { \boxed{ \tt{ \: c = - 2 \: }}}[/tex]

» Arrange the equation:

Equation is y = x - 2

The equation of the linear function in the given graph, in slope-intercept form, is: A. y = 2/3x - 2

What is the Equation of a Linear Function?

The equation of a linear function can be defined by the equation, in slope-intercept form, as y = mx = b.

slope = my-intercept = b

Slope (m) = rise/run = 2 units/3 units = 2/3

Y-intercept (b) = -2

Substitute b = -2 and m = 2/3 into y = mx + b.

y = 2/3x + (-2)

y = 2/3x - 2 (Option A)

Subtract 3x—y—z from the sum of 3x—y + z and 2x–y —z. what is the the

coefficient of x in the result?
with step pls​

Answers

Answer:

the coefficient of x is 2

Step-by-step explanation:

(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)

Apply the distributive law:  - (a - b)  = -a + b

Therefore, - (3x - y - z) = -3x + y + z

So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z

Collect like terms:                                 = 3x + 2x - 3x - y - y + y + z - z + z

Combine like terms:                              = 2x - y + z

Therefore, the coefficient of x is 2

Therefore, the coefficient of x is 2

Solution :-

As we know that ,

→ (-) × (-) = (+)

→ (-) × (+) = (-)

→ (+) × (-) = (-)

→ (+) × (+) = (+)

On using these open the brackets ,

→ -1/3 - 1( -4 + 1/6 )

→ -1/3 - 1(-4) + -1(+1/6)

→ -1/3 (-)(-)(1* 4) (+)(-) (1*1/6)

On using now above stated rules ,

→ -1/3 +4 -1/6

Somewhat rearrange ,

→ 4 -1/3 -1/6

Take (-) as common,

→ 4 - (1/3 +1/6)

Hence Option (d) & (f) are correct .

Answers

Answer:

Step-by-step explanation:

Given:

1cm = 85 km (on the map)

so map is

14 x 14 long or 85 x 85

Part A:

since the map is 14cm long, and the river is also 14 cm long, and each centimeter is equal to 85km, that means, =

14 x 85 = 1190km

so the river is 1190km long

Part B:

we can use just convert 765 into map cm to get answer,

sooo

765/85 = 9cm
