Line A has an equation of y=-2/5x + 3. What is the slope of a line perpendicular

Mathematics
1 answer:
Nat2105 [25]3 years ago
5 0

Answer:

\frac{5}{2}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - \frac{2}{5} x + 3 ← is in slope- intercept form

with slope m = - \frac{2}{5}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{2}{5} } = \frac{5}{2}

Hey there!

2ab + 2 / 2ab - 2

= 2(1)(3) + 2 / 2(1)(3) - 2

= 2(3) + 2 / 2(3) - 2

= 6 + 2 / 6 - 2

= 8 / 4

= 2


Therefore, your answer should be: 2


Good luck on your assignment & enjoy your day!

What is the factored form of the quadratic equation y=x2+4x-12? <br><br> PLEASE HELP ME!!!
snow_tiger [21]

Answer:

(x + 6)(x - 2)

Step-by-step explanation:

The given quadratic equation is $ y = x^2 + 4x - 12 $.

A quadratic equation can be factored in the form $ (x - a) (x - b) $ where $ -a $ and $ -b $ will form the roots of the equation

Here the roots are $ - 6 $ and $ 2 $.

The factored form would simply be: $ (x + 6) (x - 2) = 0 $.

Thus the answer.

The length between the bases on a Major League Baseball diamond is 90 feet. Allyson wants to make a scale drawing of a baseball
Vinil7 [7]

Answer:

\text{The scale is }\frac{1}{432}

Step-by-step explanation:

Length between the bases on a major league diamond = 90 feet

1 feet = 12 inches

90 feet = 90 × 12

             = 1080 inches

Length between the bases on a major league baseball diamond on scale drawing = 2.5 inches

\text{Scale factor = }\frac{\text{Actual length}}{\text{Scale length}}\\\\\text{Scale factor = }\frac{1080}{2.5}=432

\text{Hence, the scale is }\frac{1}{432}
