Triangle ABC has vertices located at A( 0, 2), B (2, 5), and C (−1, 7).

LuckyWell [14K]

Answer: See below

Step-by-step explanation:

Triangle ABC has vertices located at A( 0, 2), B (2, 5), and C (−1, 7)

$\begin{aligned}&A B=\sqrt{(2-0)^{2}+(5-2)^{2}}=\sqrt{13} \\&B C=\sqrt{(-1-2)^{2}+(7-5)^{2}}=\sqrt{13} \\&C A=\sqrt{(-1-0)^{2}+(7-2)^{2}}=\sqrt{26} \\&A B=\sqrt{13}, B C=A B=\sqrt{13}, C A=\sqrt{26}\end{aligned}$

B) Slope of AB line = m₁=3/2

Slope of BC line = m₂=-2/3

Slope of CA line = m₃=-5

C) $\mathrm{AB}=\mathrm{BC} \& \mathrm{AB}^{2}+\mathrm{BC}^{2}=\mathrm{CA}^{2}$

Therefore, the triangle is a isosceles right angle triangle

Francine and Cheryl received equal scores on a test made up of multiple choice questions and an essay. Francine got 34 multiple

kipiarov [429]

$34x + 14 = 30x + 22$
X is the amount the multiple choice question is worth. Both girls had the same test score so both are equal. Isolate X and that will be the value.

$34x -( 30x) + 14 = 22$
$4x = 22 - (14)$
$4x = 8$
$4x \div 4 = 8 \div 4$
x = 2

Plug 2 back in for x in the original equation to check and both girls recieved a 82%

Write the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x y = -5.

Alik [6]

Y=2x-5 because parallel means keep the slope the same and the formula is y=mx+b b is y and y is -5 so your answer is y=2x-5
