The line is given by equation y–1.5x = c. What is the value of c if the line passes through the point K (2, –3).
aleksandr82 [10.1K]

Answer:

c = -6

Step-by-step explanation:

To find the value of c to make the line pass through the point K = (2, -3), we just need to use the values of x = 2 and y = -3 in the equation, then we find the value of c.

So, we have that:

y - 1.5*x = c

(-3) - 1.5 * (2) = c

-3 - 3 = c

c = -6

So the value of c is -6

To check if the value is correct, we can use the value x = 2 and see if the value of y is -3:

y - 1.5*x = -6

y - 1.5*2 = -6

y - 3 = -6

y = -6 + 3 = -3

So it's correct.

Please answer quickly,thanks you shall be marked a branliest<br>​
Leviafan [203]

Answer:

18.0  cm to 1 decimal point.

Step-by-step explanation:

First  work out the unknown side (s) of the right triangle using the Pythagoras theorem:

s^2  = 13^2 - 5^2

       = 169 - 25 = 144

s = sqrt 144 = 12 cm.

Now consider the other triangle:

s = 12

The missing angle = 180 - 65 - 40 = 75 degrees.

By the Sine Rule:

x / sin 75 = 12 / sin40

x = 12 sin 75 / sin 40

  = 18.03

For this graph mark the statements that are true
Nitella [24]

For the graph in the figure

we know that

the function  is a quadratic equation ( vertical parabola) open up

so

The vertex is a minimum

the vertex is the point (1,0)

The domain x of the function is all real numbers-------> (-∞,∞)

The range is the interval--------> [0,∞)

f(x)\geq 0

therefore

Statements

A) The range is the set of all real numbers

Is false

B) The domain is the set of all real numbers

Is true

C) The domain is the set of all real numbers greater than or equal to zero

Is false

D) The range is the set of all real numbers greater than or equal to zero

Is true
