Answer:

2y=5+x

y=5/2+x/2

comparing with y=mx +c

where m is slope

so slope is

m =1/2

Step-by-step explanation:

Acute Angle - An angle less than 90 degrees. Right Angle - An angle that is exactly 90 degrees. Obtuse Angle - An angle more than 90 degrees and less than 180 degrees. Straight Angle - An angle that is exactly 180 degrees. Reflex Angle - An angle greater than 180 degrees and less than 360 degrees.

Answer:

An Acute angle is an angle less than 90 degrees

An obtuse angle is an angle greater than 90 degrees

A right angle is an angle that is exactly 90 degrees

A straight angle is an angle that is exactly 180 degrees

A reflex is an angle greater than 180 degrees but less than 360 degrees

Answer:

[tex]\frac{4}{9}[/tex]

Step-by-step explanation:

Step-by-step explanation:

Since y= -7x you will want to substitute the y in the other equation.

2x -(-7x) = -9

2x + 7x = -9

9x = -9

so x will be -1

y= -7(-1)

x= -1

y= 7

Answer:

x = -1 , y =7      (-1,7)

Step-by-step explanation:

[tex]y=-7x\\2x-y = -9\\[/tex]

[tex]2x+7x = -9[/tex]

[tex]2x+7x = 9x\\[/tex]

[tex]9x = -9\\[/tex]

[tex]\frac{9x}{9} =\frac{-9}{9}[/tex]

[tex]x = -1\\[/tex]

[tex]y = -7(-1)\\y = 7[/tex]

Answer:

5, -1

Step-by-step explanation:

set the given equation equal to 0.

add 9 to both sides

take the square root of both sides and remove the exponent on left side.

x-2 = +3

x-2= -3

solve for x (for each equation)

x= 5, x= -1

Answer:

1385

Step-by-step explanation:

1) the difference is d=25-8=42-25=17;

the sequence given in the condition is arithmetic one (linear relationship).

2) in order to calculate the value of the 82d term:

a(n)=a(1)+d*(n-1), where n - number of required term (it is 82), then

a(82)=8+17*(82-1)=8+1377=1385.

Answer:

Current= 13

Speed= 11

Step-by-step explanation:

Let x represent the speed of the boat

Ley y represent the rate of current

x + y= 24......equation 1

x - y= 2...........equation 2

Using elimination method

x + y= 24

+

x - y= 2

2x = 26

x = 26/2

x = 13

Sub 13 for x in equation 1

x + y= 24

13 + y = 24

y = 24-13

y = 11

Hence the current and speed of the boat when there were no current are 11 and 13 respectively

Answer:

54 republicans

50 democrats

Step-by-step explanation:

x=republicans

y=democrats

x+y=104

x=y+4

substitute for y

y+4+y=104

simplify

2y=100

y=50

x=54

Answer: 2n > -15

Step-by-step explanation:

We can use the variable n to show the unknown number.

It says that there is twice a number, meaning two of an unknown number. We can show it by using the term 2n.

It also states that 2n is greater than -15. Because of that, we can use the equation 2n > -15, to show that 2n is greater than -15.

(Quick note: The variable n just represents the unknown number, you can subsitutue any variable into its place.)

The Inequality that shows seven more than twice a number is greater than negative fifteen is; 2n > -15

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

We can consider the variable n to show the unknown number.

That says, there is twice a number, meaning two of an unknown number. We can show it by using the term "2n".

It states that seven more than twice a number is greater than negative fifteen

MEans 2n is greater than -15.

we can use the equation 2n > -15, to show that 2n is greater than -15.

Answer:

Step-by-step explanation:

To convert 10,009 to 17%, turn 17% to decimal and multiply that by 10,009 (10,009 * 0.17), which equals 1,701.53

IF you meant to convert the fraction 10,009/17% (read as "10,009 out of 17 percent, ") then simply convert 17% to a decimal (0.17) and divide 10,009 by 0.17 (10,009/0.17) which is about 58,876.47, for full decimal, use a calculator and do 10,009/0.17

The question is kind of confusing so tell me what you meant

Answer:

2/3

Step-by-step explanation:

Given :

This means that △ABC≅△ADC under the SAS congruence criterion because according to this criterion if two sides and one included angle is equal two triangles are congruent and since these two triangles fulfill these rules they are said to be congruent under the SAS congruence criterion. But they are also congruent under the ASA congruence criterion which states that if two angles and one included side is equal two triangles are congruent. Since △ABC and △ADC fulfill these rules too they can said to be congruent under the ASA congruence criterion.

Answer:

[tex]\%Tip = 13.04\%[/tex]

Step-by-step explanation:

Given

[tex]Tip= \$31.29[/tex]

[tex]Bill = \$208.60[/tex]

Required

Determine the percentage of the tip

First, we calculate the amount paid

[tex]Amount = Tip + Bill[/tex]

[tex]Amount = \$31.29 + \$208.60[/tex]

[tex]Amount = \$239.89[/tex]

The percentage of the tip is then calculated using:

[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]

[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]

[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]

[tex]\%Tip = \frac{3129}{239.89} \%[/tex]

[tex]\%Tip = 13.04\%[/tex]
