Answer 1

Answer:

son = 18 years old.

Step-by-step explanation:

Father to son = f/s = 7./3                Cross Multiply

3f = 7s

f + s = 60

f=60 - s

3(60-s)= 7s

180 - 3s = 7s

180 = 7s + 3s

180 = 10s

s = 180/10

s = 18

Use the graph to write a linear function that relates y to x.

Answers

Answer:

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

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (3, 4) ← 2 points on the line

m = [tex]\frac{4-1}{3+6}[/tex] = [tex]\frac{3}{9}[/tex] = [tex]\frac{1}{3}[/tex]

The line crosses the y- axis at (0, 3) ⇒ c = 3

y = [tex]\frac{1}{3}[/tex] x + 3 ← linear equation

0.5(5 – 7x) = 8 - (4.1 + 6)
what does x equal ​

Answers

x = 1.314286

~~~~~~~~~~

0.5(5-7x) = 8 - 4.1 - 6

0.5(5-7x)=3.9-6

0.5(5-7x) = -2.1

5-7x= - 2.1/0.5

5-7x=-4.2

-7x = -4.2 - 5

-7x=-4.2-5

-7x=-9.2

x= - 9.2/-7

x = 1.314286

What is the distance between the points (2, 10) and (-6, 4) on the coordinate
plane?
O A. 10 units
B. 100 units
C. 5 units
D. 50 units

Answers

C is the answer

5 units

The distance between the points (2,10) and (-6,4) on  the coordinate

plane is 10 units. The option A is correct option.

Given that the points are  (2,10) and (-6,4)  on the coordinate plane.

To find the distance between the given above points on the coordinate plane, the formula use:

[tex]D = \sqrt{((x_2 - x_1)^2 + (y_2 - y_1)^2)}[/tex]

Here, the value of  [tex]x_1=2, \ x_2=-6, \ y_1=10[/tex]  and  [tex]y_2=4[/tex].

Therefore, the distance between the given points on the coordinate plane, put the values in the above given formula to get,  

[tex]D = \sqrt{((-6 -2)^2 + (4 -10)^2)}\\D=\sqrt{(-8^2)+(-6)^2} \\D=\sqrt{64+36} \\D=\sqrt{100}\\ D=10 \ units[/tex]

Hence, The distance between the points (2,10) and (-6,4) on  the coordinate plane is 10 units. The option A is correct option and the distance is 10 units.
