A triangle is graphed in the coordinate plane. The vertices of the triangle have coordinates (–3, 1), (1, 1), and (1, –2). What

vladimir2022 [97]

Answer:

The perimeter of the triangle is $12\ units$

Step-by-step explanation:

Let

$A(-3,1),B(1,1),C(1,-2)$

we know that

The perimeter of triangle is equal to

$P=AB+BC+AC$

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

step 1

Find the distance AB

$A(-3,1),B(1,1)$

substitute in the formula

$AB=\sqrt{(1-1)^{2}+(1+3)^{2}}$

$AB=\sqrt{(0)^{2}+(4)^{2}}$

$AB=4\ units$

step 2

Find the distance BC

$B(1,1),C(1,-2)$

substitute in the formula

$BC=\sqrt{(-2-1)^{2}+(1-1)^{2}}$

$BC=\sqrt{(-3)^{2}+(0)^{2}}$

$BC=3\ units$

step 3

Find the distance AC

$A(-3,1),C(1,-2)$

substitute in the formula

$AC=\sqrt{(-2-1)^{2}+(1+3)^{2}}$

$AC=\sqrt{(-3)^{2}+(4)^{2}}$

$AC=5\ units$

step 4

Find the perimeter

$P=AB+BC+AC$

substitute the values

$P=4+3+5=12\ units$

Solve for x y=×/c+b

Alex17521 [72]

$\text{Hello there!}\\\\\text{Solve for x:}\\\\y=\frac{x}{c}+b\\\\\text{Multiply both sides by c to cancel the c out of the denominator}\\\\yc=x+bc\\\\\text{Subtract both sides by bc}\\\\yc-b=x\\\\\boxed{\text{Answer: yc - bc = x}}$

Express as a sum:<br> a-5<br> m-n<br><br> Express as a difference:<br> 7+3<br> a+5<br> a+b

NeTakaya

Answer:

Step-by-step explanation:

a-5 = -5+a

m-n = m + (-n)

7+3 = 7 - ( -3)

a+5 = a - (- 5)

a+b = a - (-b)
