(4,?) is on the line below. find the other half of the coordinate. y=2/7x+3

Savatey [412]

Since we have (4,?) we know x=4. Substitute this into the equation and solve for y.

y= 2/7*4+3

y= 2/7*4/1+3

y= 8/7+3

y= 8/7 + 3/1

y= 16/14 + 42/14

y= 58/14 or 4.14

Maths question I'm struggling with.

Alex17521 [72]

Answer:

A = 2.63

B = 2

Step-by-step explanation:

To find the population density, what we need to do simply is divide the population by the area of the UK

mathematically, that would be;

(6.41 * 10^7)/243,610 = 263.125

To the nearest whole person= 263 people/ square meter

So now we want to write 263 in standard form = 2.63 * 10^2

So this means A = 2.63 and B = 2

Is the following relation a function?<br> Yes<br> No

svetlana [45]

Answer:

Yes

Step-by-step explanation:

Because each value of x gives one and only one value of y

conversely, if each value of x gives more than one value for y, then it is not a function.

An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15. 7 inches, so the equ

brilliants [131]

The lengths that make the sense for the value of b are 0.5 inches and 2 inches.

<h2>Given </h2>

An isosceles triangle has two sides of equal length, a, and a base, b.

The perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7.

<h3>What is the triangle inequality theorem?</h3>

If two sides of a triangle are unequal, the longer side has a greater angle opposite to it.

$\rm a+a > b\\\\2a > b$

The equation of the perimeter of the triangle;

$\rm 2a+b = 15.7\\\\2a = 15.7-b\\\\a = \dfrac{15.7-b}{2}$

1. Substitute b = 0.5 in the equation;

$\rm a = \dfrac{15.7-b}{2}\\\\ a = \dfrac{15.7-0.5}{2} \\\\ a = \dfrac{15.2}{2}\\\\a = 7.6$

Then,

Verify the triangle inequality theorem;

0.5 + 7.6 > 7.6 is true

7.6 + 7.6 > 0.5 is true

2. Substitute b = 2 in the equation;

$\rm a = \dfrac{15.7-b}{2}\\\\ a = \dfrac{15.7-02}{2} \\\\ a = \dfrac{13.7}{2}\\\\a = 6.85$

Then,

Verify the triangle inequality theorem;

0.5 + 76.85 > 6.85 is true

6.85 + 6.85 > 2 is true

Hence, the lengths that make the sense for the value of b are 0.5 inches and 2 inches.

Question 1 of 10

statuscvo [17]

Answer:

slope is -1

Step-by-step explanation:

Slope of the line is changes in y over changes in x. It can also be referred as rise over run.

We can express mathematically as:

$\displaystyle{m=\dfrac{y_2-y_1}{x_2-x_1}}$

where m is slope.

Let (-2,5) be $\displaystyle{(x_2,y_2)}$ and (6,-3) be $\displaystyle{(x_1,y_1)}$ . Hence, apply the slope formula:

$\displaystyle{m=\dfrac{5-(-3)}{-2-6}}\\\\\displaystyle{m=\dfrac{5+3}{-8}}\\\\\displaystyle{m=\dfrac{8}{-8}}\\\\\displaystyle{m=-1}$

Therefore, the slope is -1
