What is the slope of a line of best fit if its equation is y = −2x + 3?

−2
Negative 1 over 2
1 over 3
3

Answer:

102º

Step-by-step explanation:

So you know that ABC is an Isosceles triangle as AB=AC therefore, angle ABC is equal to angle ACB.

You also know that even though it doesn't look like it, ABP is an equilateral triangle as AB, AP and BP are equal so all those angles must equal 60º.

So:

ABC = 60 - 21 = 39º

and since ABC= ACB

ACB also equals 39º.

Because angles in a triangle add to 180º, BAC is consequently:

180- (39+39) = 180 - 78 = 102º

BAC = 102º

Answer:

-7x - 14

Step-by-step explanation:

By simplifying the expression:

-3(2x+5) - (x - 1)

-6x-15 -x + 1

-7x - 14

Answer:

-7x - 14

Step-by-step explanation:

You can use the distributive property to find an equivalent expression.

Distribute -3 to 2x + 5.

(-3 × 2x) + (-3 × 5) = -6x + (-15) = -6x - 15

Distribute -1 to x - 1. (It is -1 because there is always a 1 in front of things like x = 1x and (x + 1) = 1(x + 1). 1 times anything equals the number it is multiplied by. There is a - sign in front of the parenthesis, which makes the invisible 1 a -1.)

(-1 × x) + (-1 × -1) = -x + 1

You can simplify the expression.

(-6x - 15) + (-x + 1) = -7x - 15 + 1 = -7x - 14

Answer:

10

Step-by-step explanation:

The current probability of picking a red ball is [tex]\frac{x}{15}[/tex]. When 5 more balls are added, the probability is 3/4. We can write a ratio for this problem:

[tex]\frac{x+5}{15+5} = \frac{3}{4}[/tex]

When using cross multiplication to solve this, you get 3 * 20 = 4(x+5).

60 = 4x + 20

40 = 4x

x = 10 red balls

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

1. Subtract the 4x on both sides = -14 = -2x

2. Divide -2 on both sides to get -14/-2 = x

3. -14/-2 = 7 so 7 = x

Answer:

They both are a 90 degree angle.

For the parallelogram KLMN, opposite angles K and M are equal.

Parallelogram are type of quadrilateral in two dimensional geometry which has four sides, four vertices and four angles where opposite sides are equal. They also have the two pairs of sides parallel to each other. These sides are opposite sides.

The sum of the adjacent angles of the parallelogram is equal to 180 degrees and the sum of all angles is equal to 360 degrees. Also the opposite angles are equal.

Given that KLMN is a parallelogram.

Here K and M are opposite vertices and also L and N are opposite vertices.

In a parallelogram, we know that measure of opposite angles will be equal. So here, measure of angles K and M are equal.

Therefore, since angles K and M are opposite angles of the parallelogram, they are equal.

Answer:

4). 3

5). 600

Step-by-step explanation:

formula of finding intrest earned is (p×r×t)/100

by putting this formulae____

( HERE p means principal , r means rate , t means time )

(p×r×t) /100= interest

(480×r×5) / 100=100.80

(336×r) / 100 = 100.80

336×r= 100.80×100

r= (100.80×100)/336

r=3

5). (p×r×t)/100=interest

(p×4×5) /100 = 120.00

p×4×5 = 120.00×100

p= 12000 / 4×5

P=12000/20

P=600

Answer:

The black line has the greater slope.

Step-by-step explanation:

One way to think about which line has the greater slope is to imagine (or draw) a car on top of each line driving from left to right. If the car is driving up a steeper hill then the slope is greater.

To show your work though, starting at the y-intercept on the black line, find another point that you can see well on the line such as (3, 4). To get from the y-intercept to (3,4) go up 2 and right 3 so the slope is 2/3.

For the blue line, find a point that is easy to see such as (2, 3). To get from the y-intercept to (2, 3) go up 1 and right 2 so the slope is 1/2.

(Remember slope is y/x or rise/run)

Since 2/3 is bigger than 1/2, the slope of the black line is greater.

Answer:

4 baskets

Step-by-step explanation:

Since 170 divided by 46 equals 3 with a remainder of 32, you use the remainder,32, and change it to one more basket so 3+1=4 so Kira needs 4 baskets.

Answer:

Kira will require exactly four baskets.

Step-by-step explanation:

The given information we know is..

- Kira is responsible for transporting 170 apples from a farm to the market.

- Each basket has a capacity of 46 apples.

We must divide 170 apples by 46 apples in order to solve this problem.

170/46 ( When I use the / symbol, it indicates to divide.)

170/46 = 3.69565217391

We'll have to round it up because we can't actually accept 3.69 bags. So the answer is 4 baskets.

Kira will need approximately 4 baskets.

Hope this helps! :D

Answer:

22x - 14

Step-by-step explanation:

pretty sure its like this..

3(4x-3)+5(2x-1)

= 3×4x + 3×(-3) + 5×2x + 5×(-1)

= 12x + (-9) + 10x + (-5)

and according to the rules of multiplying negative by positive...

= 12x - 9 + 10x - 5

combine like terms using the symbols on its left

= 12x + 10x - 9 - 5

= 22x - 14

Answer:

Alright so the question states that "She can only spend $3."

A sticker costs $0.35

A eraser is $0.99

A pencil costs $0.59

What you are trying to find is Can Linda buy 3 stickers and 2 erasers.

So add the total value of stickers prices. You need to know what's the cost of 3 stickers and 2 erasers

0.35+0.35+0.35= 1.05+0.99+0.99 = 3.03 So she can't. Now can she buy 1 sticker, 1 eraser, and 1 pencil. So is it enough to get 1 of each item?

0.35+0.99+0.59=1.93 Yeah you can.

But is it enough for her to get 3 stickers, 2 erasers and a pencil?

We already know the cost for 3 stickers and 2 erasers is $3.03. All you need to do is add $0.59 to find the total cost. The total cost of 3 stickers and 2 erasers and a pencil is $3.62. So the answer is No, because the total will be $3.62 and her budget is $3 so she will need extra $0.62 to cover the full cost.
