By rounding both numbers to the nearest hundred, we can estimate a sum of 400. Using the tool to model 325 + 169, we find the exact sum is: A) 400 B) 500 C) 494 D) 495

Answers

Answer 1

Answer: To estimate the sum of 325 and 169 by rounding to the nearest hundred, we round both numbers:

325 rounds to 300
169 rounds to 200

Now, let's add these rounded numbers:

300 + 200 = 500

So, the estimated sum is 500.

Now, to find the exact sum of 325 + 169:

325 + 169 = 494

So, the exact sum is 494.

The correct answer is C) 494.

Find a point-slope form for the line with slope 1/5 and passing through the point (-8, - 9).The equation of the line in point-slope form is ______?

Answers

Answer:

$y+9=(1)/(5) (x+8)$

Step-by-step explanation:

Pre-Solving

We are given that a line has a slope (m) of 1/5, and passes through the point (-8, -9).

We want to write the equation of this line in point-slope form.

Point-slope form is given as $y-y_1=m(x-x_1)$ , where m is the slope and $(x_1,y_1)$ is a point.

Pre-Solving

As we are given both the slope and the point, we can plug those values into the equation.

Starting with the slope, we can replace m with 1/5.

$y-y_1=(1)/(5) (x-x_1)$

Now, substitute -8 as $x_1$ and -9 as $y_1$ . We get:

$y--9=(1)/(5) (x--8)$

This can be simplified to:

$y+9=(1)/(5) (x+8)$

Answer:

y=1/5(x+8)-9

Step-by-step explanation:

Point Slope Formula: y=m(x-x1)+y

y=1/5(x+8)-9

Which graphs represent functions?

Answers

Answer:

A. Only graph B and D

Step-by-step explanation:

Hi, to answer this question we have to analyze the options given:

A function has only one output value (y) for each input value.(x)

In other words, If we draw a vertical line (anywhere on the graph) that intersects the graph in two points or more, then the graph does not represent a function because that x value has more than one output(y).

So, the correct option is:

A. Only graph B and D

How would i do this problem
slope= -2, y-intercept = 7

Answers

SINCE the slope is -2 it would be like this -2/1 but first plot the y-intercept onto the graph and go down 2 and over 1.

the equation of the line is
y=mx+c
y=-2x+7
