The three side lengths of four triangles are given. Which triangle is a right triangle? Triangle 1: 13. 6,7 O Triangle 2: 7, 8, 13 O Triangle 3: 10, 11, 12 O Triangle 4: 10.9,8​

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

if x decreases by 4 then y increases by 10

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
