What is the equation of the following line? (7,2) (0,0)

butalik [34]

Answer:

Step-by-step explanation:

(7,2) , (0,0)

slope = (y2 - y1) / (x2 - x1) = (0 - 2) / (0 - 7) = -2/-7 = 2/7

y = mx + b

slope(m) = 2/7

(0,0)...x = 0 and y = 0

now sub

0 = 2/7(0) + b

0 = b

ur equation is : y = 2/7x + 0.....same as y = 2/7x <====

Simplify (4x − 6) + (5x + 1). 9x + 5 9x − 5 x − 5 −x − 5

Bad White [126]

Answer:

$9x-5$

Step-by-step explanation:

$(4x - 6) + (5x + 1)$

To simplify the given expression, we need to remove the parenthesis

$4x - 6+ 5x + 1$

To simplify it we combine like terms

the terms that has same variables are like terms

$4x+5x= 9x$

$-6+1= -5$

The given expression becomes

$9x-5$

Please answer correctly

Sonbull [250]

Answer:

The answer is 6 and -6

Step-by-step explanation:

The given equation is
$x^2 - kx + 9 = 0 ... (1)$

where a = 1. b = -k, c = a

since the equation (1) has equal roots

$\Rightarrow b^2 - 4ac = 0 \newline\\\Rightarrow (-k)^2 - 4(1)(9) = 0\\ \newline\\\Rightarrow (k)^2 - 36 = 0 \newline\\\Rightarrow k^2 = 36 \newline\\\Rightarrow k = \pm 6$

Hence volume of k = 6, -6

the point (3, 0) lies on a circle with the center at the origin. What is the area of the circle to the nearest hundredth?

natima [27]

Area of a circle is π·r²
The center of the circle is at the origin (0,0) and there is a point at (3,0)
This means that the radius (r) of the circle is 3.
Therefore the area of the circle is 9π or 28.27
