En un examen con 20 preguntas, la respuesta correcta cuenta cuatro puntos, la respuesta incorrecta -3 y en blanco -1 entonces contesto a 10 preguntas bien, en tres mal y el resto las dejo en blanco, ¿que puntuación obtendría obtendrían el examen?

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
