find the slope of the line 3x - 8y = -20

Answers

Answer 1

[tex]\huge\boxed{\frac{3}{8}}[/tex]

To get the slope of a line from its standard form ([tex]Ax+By=C[/tex]), we can use [tex]m=-\frac{A}{B}[/tex].

[tex]\begin{aligned}m&=-\frac{A}{B}\\&=-\frac{3}{-8}&&\smash{\Big|}&&\text{Substitute in the known values.}\\&=\boxed{\frac{3}{8}}&&\smash{\Big|}&&\text{The negatives cancel out.}\end{aligned}[/tex]

Alternatively, we could have changed the equation to slope-intercept form and found the slope from there.

A distrubutor wants to make 1,000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is 20% raisins. How many pounds of each should he use?

Answers

Answer:

He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins

Step-by-step explanation:

System of Equations

Let's call

x = pounds of trail mix 5% raisins

y = pounds of trail mix 20% raisins

The distributor wants to make 1,000 pounds of trail mix, thus:

x + y = 1,000     [1]

The mix must be 8% raisings as a combination of x and y, thus:

5x + 20y = 8*1,000 = 8,000

Dividing by 5:

x + 4y = 1,600     [2]

Subtracting [2] and [1]:

4y - y = 1,600 - 1,000

Operating:

3y = 600

y = 200

From [1]

x = 1,000 - y = 1,000 - 200

x = 800

He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins

Answer:

5% raisin mix: 800 lbs

20% raisin mix: 200 lbs

Step-by-step explanation:

Let number of 5% be x; and number of 20% be a.

x + y = 1000

5% · x + 20% · y = 8% of 1000 pounds

0.05x + 0.2y = 80

x = 1000 - y

0.05(1000 - y) + 0.2y = 80

50 - 0.05y + 0.2y = 80

0.15y = 30

y = 200

x = 1000 - y

x = 1000 - 200

x = 800

Nikki just graduated from high school and would like to buy a car. If she received $3000 in graduation gifts from family friends. She will put this money into a 18 month certificate of deposit until she finds the car of her dreams. The CD earned 10% annually and simple interest. How much will she put towards the down payment and 18 months 1.5 years?

Answers

Answer:

$3450

Step-by-step explanation:

Here, P = $3000, N = 1.5 years, R = 10%

[tex]SI = \frac{PNR}{100} \\ \\ SI = \frac{3000 \times 1.5 \times 10}{100} \\ \\ SI = 450 \\ \\ [/tex]

Amount of down payment

= $3000 + $450

= $3450

what two numbers multiply to -36 and add up to 5

Answers

Answer:

9 and -4

Step-by-step explanation:

Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.

First, test if they multiply to -36:

9(-4)

= -36

Then, check if they add up to 5:

9 + (-4)

= 5

So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5

For 5)
The angles inside a triangle adds up to 180 degrees.
A triangle that has an angle at 90 degrees is a right triangle
A triangle that has an angle greater than 90 degrees is an obtuse triangle
A triangle that has 3 different angles is an scalene triangle.
a) subtract 25 and 65 from 180 is 90- this is a right triangle
b) notice an angle 109 is greater than 90, this is an obtuse triangle
c) subtract 58 and 32 from 180 is 90- this is a right triangle
d) subtract 61 and 63 from 180 is 56, all angles are different - this is a scalene triangle

Answers

Answer and Step-by-step explanation:

Given that if a polygon is a square, then a polygon is a quadrilateral, we find the converse, inverse and contrapositive of this implicational statement. The hypothesis is the causative statement and the conclusion is the resultant effect

The converse of this statement is the reverse of its statements hence:

If a polygon is a quadrilateral then a polygon is a square

The inverse of this statement is the negation of the statements hence :

If a polygon is not a square then a polygon is not a quadrilateral

The contrapositive of the statement is the interchange of the hypothesis and conclusion of the inverse statement hence:

If a polygon is not a quadrilateral then a polygon is not a square

SLOPE HELP

hey, this just help if you're confused about slopes because I've seen a few questions about them I'll clear up a few things!
slope formula is y2-y1/x2-x1
memorize that and you'll be able to find your slope!
if you're given 2 points please label them (3,4) (0,6) labeling is this >>> (x1 3, y1, 4)
(x2 0, y2 6)
this makes it so it's organized and you know what you're subtracting
trust me I'll try to do it in my head and calculate it with a calculator then forget what points I used so WRITE IT DOWN! lol
if you hear parallel it's the same slope!
if you hear perpendicular it's the negative reciprocal example: 3/4x the perpendicular slope would be -4/3x
if you have a point and a slope and a line plugin the point to your line! let's say this one is parallel so the same slope
(3,4) y=3/4x + 2
4=3/4(3)+b
and solve for b!
anyways hopes this helps-
