Slope = four fifths ,y-intercept = -1

1 answer:

5 0

Slope-intercept form:
y=mx+b

m=slope
b=y-intercept

Data:
m=4/5
b=-1

y=mx+b
y=(4/5)x-1

Answer: the equation of the line with slope=4/5, and y-intercept=-1 would be:
y=(4/5)x-1

Which of the following represents the additive inverse of 125? A. -(-125) B. 125 C. -125 D. 1/25

Elden [556K]

Additive inverse of 125 is – 125, option C is correct.

Solution:

Given that , a number is 125

We have to find the additive inverse for the above given number from the above given set of options.

Now, we know that, sum of a number and its additive inverse equals to 0.

So, let us check option by option.

Option A:

Given number is -(-125)

-(-125) ⇒ 125 + ( - ( - 125 ) )

⇒ 125 + 125

⇒ 250 ⇒ wrong option

Option B:

Given number is 125

⇒ 125 + 125 ⇒ 250 ⇒ wrong option

Option C:

Given number is -125

125 + ( - 125 ) ⇒ 125 – 125 ⇒ 0 ⇒ correct option

Hence, additive inverse of 125 is – 125, option C is correct

use the circle graph show below to answer the question a pie chart labeled favorite sports to watch is divided into into three p

mart [117]

From the pie chart described, the percent of people that responded that football was their favorite sport to watch is 42% which represents 210 of the people surveyed.

Let the number of people surveyed be x, then

$42%\ of\ x=210 \\ \\ \Rightarrow0.42x=210 \\ \\ \Rightarrow x= \frac{210}{0.42} =500$

Therefore, the number of people surveyed is 500 people.
