The correct answer is D. If you look at the equation you can see that the line crosses at the points (1,5) and (-2, -4). Use this set of ordered pairs to find the slope. (-4-5)/(-2-1) = (-9/-3) = 3 The use the point-slope formula and fill in the ordered pair (1,5) with the slope. y - 5 = 3( x - 1)

Answer:

Both triangles are right triangles because the angle d is 90 degrees in both sides

3 ^ 2 - 2.25^2 = 1.98

4^2 - 1.98^2 = 3.48

x = 3.48

Answer:

There is a circle with a diameter[d] of 2.

Step-by-step explanation:

the Radius=diameter /2=2/2=1 units

now

circumference=2πr=2×π×1=6.29=6 units

area=πr²=3.14 unit²

Write the equation of the line through (-2,1) and parallel to y= -3x+1

DedPeter [7]

Use point slope equation y-y1=m(x-x1) Remember that a parallel line has the same slope.

y-1= -3(x-(-2))
y-1= -3(x+2)
y-1= -3x-6
y= -3x-5

Final answer: y=-3x-5

Determine whether the ordered pair (1, 1) is a solution of the inequality. y ≤ -3x+1

Answer: $\textsf{(1, 1) is NOT a solution of the inequality}$

-------------------------------------------------------------------------------------------------------------

Given: $y \le-3x + 1$

Find: $\textsf{Determine if (1, 1) is a solution of the inequality}$

Solution: In order to determine if (1, 1) is a solution we need to plug in 1 for the x values and 1 for the y values and see if the equation evaluated to true.

<u>Plug in the values</u>

$y \le-3x + 1$

$1 \le-3(1) + 1$

<u>Simplify</u>

$1 \le-3 + 1$

$1 \le-2$

As we can see the expression states that 1 is less than or equal to -2 which is false therefore (1, 1) is NOT a solution of the inequality.
