<h3>Answer: C) 4/7</h3>

Explanation:

The given equation is in the form y = mx+b with slope m = -7/4

Take the negative reciprocal of this to get 4/7. We simply flip the fraction and the sign (from negative to positive).

Note that multiplying any original slope with its perpendicular counterpart, will always get you -1

(-7/4)*(4/7) = -1

This applies to lines that are not vertical and not horizontal.

Answer:

Step-by-step explanation:

The slope of the given line is -7/4

Let the slope we want be m :

Then m * -7/4 = -1 ( as the slopes of perpendicular lines have a product of -1)

m = -1 / -7/4

= 1 * 4/7

= 4/7.

Since Angles B and C are equal, the sides AB and AC must also be equal, so you can set the equations equal to each other and solve for x. Then to find the length of BC, x can be plugged into the equation for that side length.

4x+4=6x-14
Add fourteen to each side to get x alone on the right side
4x+4+14=6x-14+14
4x+18=6x
Subtract 4x from each side to get all of the x's on one side of the equation
4x+18-4x=6x-4x
18=2x
Divide each side by two to find the value of one x
18/2=2x/2
9=x
Now that you know x equals 9, plug that into the equation for side length BC:
2x+7
2(9)+7
Multiply 2 by 9 to get rid of the parentheses
18+7
Add to simplify
25

The side of the triangle, BC, equals 25

Show me step by step multiplication on how to answer : 1 2/5 x 1/4

Phantasy [73]

Answer:

Step-by-step explanation:

What i would do is turn the first one into an improper fraction

7/5 x 1/4

it's easier to multiply this way

see if you can simplify any of the terms first

7 1

5 4

none of the numbers can be broken down further so we just multiply straight across

7 x 1 is 7

5 times 4 is 20

so the answer would be 7/20
