Find the solution of this system of equations x-8y=21 and 3x--8y=15

devlian [24]

If you would like to find the solution of the system of equations, you can do this using the following steps:

x - 8y = 21 /*(-3)
3x - 8y = 15
______________
-3x + 24y = -63
3x - 8y = 15
______________
-3x + 24y + 3x - 8y = -63 + 15
16y = -48 /16
y = -48/16
y = -3

x - 8y = 21
x = 21 + 8y
x = 21 + 8 * (-3)
x = 21 - 24
x = -3

(x, y) = (-3, -3)

The correct result would be (-3, -3).

If f(x)= mx+ c , f (1)=5 and f(-2)=-1

taurus [48]

Answer:

$y = 2x + 3$

Step-by-step explanation:

We can find the slope.

$\frac{ 5 + 1}{1 + 2 } = 2$

so m is 2

$y = 2x + c$

Plug one the equations in to find c.

$- 1 = 2( - 2) + c$

$- 1 = - 4 + c$

$3 = c$

so the equation is

$y = 2x + 3$

Please help asap!!!! 53 points!

AfilCa [17]

The easiest way is to graph it based upon the slope (m) and y-intercept (b), in the standard slope-intercept form: y = m (x) + b.
The line above intercepts the y-axis at y = -2, which is b. The slope (m) = rise/run = (y2-y1)/(x2-x1 ); so for the point (-4, 2) to (-6, 4) is:
(4-2)/(-6--4) = 2/(-6+4) = 2/-2 = -1.
So one form of the equation would be:
y = -1x - 2
Now the other form of an equation is point-slope: y-k = m (x-h), where the point is at (h, k)
and if we pick -5 for x (bc 5 it listed in 3 of the answers), the y at x=-5 looks like around +3
so we get: y-k = -1 (x--5)...
y-3 = -(x+5)... therefore D) is the correct answer:

Answer:

Area of rectangle = 40 square units

Step-by-step explanation:

Points to remember

Distance formula

Length of a line segment with end points (x₁, y₁) and (x₂, y₂) is given by,

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Area of rectangle = Length * Breadth

To find the length and breadth

Here a rectangle with vertices at (7, 3), (12, 3), (12, 11), and (7, 11)

Length1 = √[(x₂ - x₁)² + (y₂ - y₁)²]

√[(12 - 7)² + (3 - 3)²] = √5² = 5

Length2 = √[(x₂ - x₁)² + (y₂ - y₁)²]

√[(12 - 12)² + (11 - 3)²] = √8² = 8 units

Therefore Length of rectangle = 8 and

Breadth of rectangle = 5 units

To find the area of rectangle

Area = Length * Breadth

= 8 * 5 = 40 square units
