What is the point-slope form of a line that has a slope of 3 and passes through the point (–1, 4)? y – (–1) = 5(x – 4) 4 – y1 = 3(–1 – x1) y – 3 = –1[(x – (–4)] y – 4 = 3[(x – (–1)]

y – 4 = 3[(x – (–1)]

Step-by-step explanation:

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
