A triangle has 180 degrees.
So, you know 63+43=106.
180-106=74
So the third angle is 74 degrees.

ipn [44]

Answer:

Linear, the linear term is -21x and the constant term is -20. Last option is the answer

Step-by-step explanation:

We are given the following function:

y = (x - 5)(5x + 4) - 5x^2

First we have to simplify y, before solving the question:

y = (x - 5)(5x + 4) - 5x

Applying the distributive property:

y = 5x^2 + 4x - 25x - 20 - 5x^2

y = 0x^2 - 21x - 20

y = -21x - 20

No quadratic term, so it is linear.

The linear term is -21x and the constant term is -20.

Lin multiplies 7/8 times a number.the product is less than 7/8 . Which could be Lin’s number ?
igor_vitrenko [27]

Answer:

Any number less than 1

Step-by-step explanation:

Let x be the number Lin multiplies by 7/8. So, we have:

(7/8)*x < 7/8

We need to find the possible values for x. Lets start by dividing both sides of our inequality by (7/8) in order to get x alone on the left side.

(7/8)*x / (7/8) < (7/8)/(7/8)

Reordering:

(7/8) / (7/8) * x < (7/8)/(7/8)

As any number divided by itself (except from 0) is equal to 1:

x < 1

So, the number that Lin multiplied by 7/8 MUST be less than 1. This is evident, as any positive number multiplied by a number less than 1 will decrease, doesn't matter if its a negative or positive number.

So, such number is less than 1. Any number less than 1 could be Lin's number.
