A recipe asks that the following three ingredients be mixed together as follows: add 1
2
of
a cup of flour for every 1
2
of a teaspoon of baking
soda, and every 1
4
of a teaspoon of salt.
Which of the following rates are unit rates
equivalent to the ratios shown above? Select two
that apply

Which rational number could be graphed between -4 and -5

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
