Step-by-step explanation:

3(4x + 5) = 33 \\  \\  \therefore \: 12x + 15 = 33 \\  \\ \therefore \: 12x = 33 - 15 \\  \\ \therefore \: 12x = 18 \\  \\  \therefore \:x =  \frac{18}{12}  \\  \\ \huge \red{ \boxed { \bold{ \therefore \:x = 1.5}}}

In a New York Times/CBS News Poll, respondents were asked if it should be legal or illegal to send a text message while driving.
AnnZ [28]

Answer: \dfrac2{201}

Step-by-step explanation:

Number of persons said it is legal to text while driving = 8

Number of persons said it is illegal to text while driving = 804

Total persons sampled = 804+8 = 812

Since probability =\dfrac{\text{favorable outcomes}}{\text{Total outcomes}}

The probability of randomly selecting someone who believes it should be legal to text while driving = \dfrac{8}{804}=\dfrac2{201}

Required probability = \dfrac2{201}

Write the equation of the line perpendicular to + = that passes through (−,−). Write your answer in slope-intercept form.
Ad libitum [116K]

Answer:

y = 0.25x - 5

Step-by-step explanation:

Given line is 4x + y = 3

or y = -4x + 3

Comparing this with slope-intercept form y = mx + c :

slope of this line is -4

Product of slopes of perpendicular lines = -1

⇒ slope of a line perpendicular to this is \frac{-1}{-4} = \frac{1}{4} = 0.25

This line also passes through the point (-4,-6)

The equation of a line having slope m and passing through a point (h,k) is

y - k = m(x - h)

⇒ equation of line perpendicular to given line is y - (-6) = 0.25×{x - (-4)}

⇒ y + 6 = 0.25×(x + 4)

⇒ y + 6 = 0.25x + 1

⇒ <u>y = 0.25x - 5</u>

This is in the slope-intercept form y = mx + c with slope m = 0.25 and y-intercept (0,-5)
