Which is the slope of the line that passes through the points (−3,1) and (4,−2)?


CLEAR CHECK

slope =−3

slope =−37

slope =12

slope =−73

Answers

Answer:

The slope of the line is [tex]-\frac{3}{7}[/tex] ⇒ B

Step-by-step explanation:

Let us revise the rule of the slope

The rule of the slope of the line is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

(x1, y1) and (x2, y2) are two points lie on the line

∵ The line passes through the point (-3, 1) and point (4, -2)

→ That means one of them is (x1, y1) and the other is (x2, y2)

x1 = -3 and y1 = 1

x2 = 4 and y2 = -2

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{-2-1}{4--3}[/tex] = [tex]\frac{-3}{4+3}[/tex]

m = [tex]-\frac{3}{7}[/tex]

The slope of the line is [tex]-\frac{3}{7}[/tex]

What is the slope of a line parallel to the line whose equation is 3x – 3y = -45.
Fully reduce your answer,

Answers

Answer:

One

Step-by-step explanation:

A parallel line has the same slope of the original graph. Because of this, all we need to do is put the equation you gave into slop-intercept form, or:

y = mx + b

Don't forget that m is the slope, and b is the y-intercept!

3x - 3y = 45

-3y = -3x + 45

y = x + 15

Compare this to the equation of the slope-intercept form and look for m:

y = mx + b

There's nothing in front of the variable! No worries, that's the same thing as saying 1x.

But mathematicians are a little lazy (lol) and they don't want to mistake the number 1 for the lowercase letter L or a capital i. Because of that, they made 1x equal x.

Long story short, the slope for the equation (3x – 3y = -45) is one. And because parallel lines have the same slope as their original counterparts, the slope is one as well!

I recommend trying a few other problems like these. You'll end up using them a lot in the future!

Good luck and keep studying!

Your have money in your wallet, but you don't know the exact amount. When a friend asks you, you say that you have 50 dollars give or take 15. Use an absolute value equation to find least and biggest amount of money in your pocket?​

Answers

Answer:

boom bam

Step-by-step explanation:

x - 50 = 15

x - 50 + 50 = 15 + 50

x = 65

Equation #2

x - 50 = -15

x - 50 + 50 = -15 + 50

x = 35

The least amount is 35 dollars and the biggest amount is 65 dollars.

Answer: $45

EXPLANATION:If you have 50 dollars, to find the least amount SUBTRACT the $15 not add.

50 - 15 = $45.

Answer: Carlos rode further than on Saturday by  107/56 miles.

Step-by-step explanation: We are given Carlos biked on Saturday = 139/8 miles.

He biked on Sunday = 135/7 miles.

Let us find which fraction is greater by finding common denominator.

LCM of 7 and 8 is 56.

Therefore, Common denominator of 139/8 and 135/7 is 56.

Converting each fraction as denominator 56.

139×7/8×7 = 973/56

135×8/7×8 =  1080/56.

We can see that 1080/56 is greater than 973/56.

On subtracting 973/56 from 1080/56, we get

1080/56 - 973/56 = 107/56

2) A hike starts at an elevation of 13 4/5 feet below sea level and ends at an elevation that is 1,542 feet higher. How high is the hiker, in feet, above sea level at the end of the hike?

a) 1,528

b) 1,528 1/5

c) 1,555

d) 1,555 4/5

Answer: B 1,528 1/5

You and a friend are knitting a scarf that will be 72 inches long. Your friend knits the first 24 inches and then gives you the scarf to finish. You expect to knit at a rate of 8 inches per day.

Answers

The total length is 72 inches, and our friend has already done 24 inches. Therefore we will take off 24 from 72, which gives us 48.

At a rate of 8 inches per day, we can work out how long it will take us by doing 48 divide 8, which is 6.

Therefore it would take you 6 days to finish the scarf.

Brandon is hiking a trail that leads to the top of a canyon. The trail is 4.2 miles long, and Brandon plans to stop for Lunch after he completes 1.6 miles. What expression represents the remaining distance Brandon needs to hike?

Answers

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that the trail that Brandon is hiking is 4.2 miles long, and Brandon plans to stop for Lunch after he completes 1.6 miles.

The expression represents the remaining distance Brandon needs to hike will be gotten by subtracting 1.6 miles from 4.2 miles. This will be:

= 4.2 - 1.6

= 2.6 miles

Jennifer says the quadrilaterals below must be congruent because their angles are congruent. Is she correct?

Answers

I've attached the complete question withe the 2 quadrilaterals.

Answer:

Jennifer is not correct because equal angles alone is not a proof of congruency.

Step-by-step explanation:

Now, in test for congruence, we use any of the following criteria;

SSS: Side - Side - Side

SAS: Side - Angle - Side

ASA: Angle - Side - Angle

AAS: Angle - Angle - Side

RHS: Right angle - Hypotenuse - Side

The assumption in the question is that all the angles are equal to determine that the quadrilaterals are congruent.

However, we don't use AAA(Angle - Angle - Angle theorem) as a congruence proof because it's very possible to have all the internal angles equal and yet all the corresponding sides don't have the same length.

Thus, Jeniffer is not correct.

If triangle ABC is reflected over the x-axis, triangle A'B'C' will be created.

A while back, either James borrowed $12 from his friend Rita or she borrowed $12 from him, but he can’t quite remember which. Either way, he is planning to pay her back or ask that she pay him back this afternoon. If he has $42.80 in his wallet, which equation represents the amount of money he may have after he sees Rita?

|x – 42.80| = 12
|x + 42.80| = 12
|x – 12| = 42.80
|x + 12| = 42.80

Answers

Answer:

|x – 42.80| = 12

Step-by-step explanation:

x – 42.80 = -12

x=30.8

x – 42.80 = 12

x=54.8

|x - 42.80| = 12  equation represents the amount of money James may have after he sees Rita

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The equation that represents the amount of money James may have after he sees Rita is |x - 42.80| = 12.

This equation reflects the fact that James either borrowed $12 from Rita

so he would subtract $12 from his current amount, or Rita borrowed $12 from him, so he would add $12 to his current amount.

Therefore, the  |x - 42.80| = 12  equation represents the amount of money James may have after he sees Rita
