Ao desenhar um triangulo, Heitor aproveitou um dos cantos da folha de seu caderno retangular, que formara um dos vértices do triangulo. Para finalizar o desenho, o maior ângulo inteiro que ele pode usar, medindo com um transferidor, e A 1. B 60. C 89. D 90

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

a.for lorena 14 hours makes $126   for 16 hours she makes 144

for julie 6 hours makes $72 for 21 hours its $252

b. julie makes more money than lorena julie makes $12 an hour and lorena makes $9  

.

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5
