Answer:

The bottom graph

Step-by-step explanation:

The reason for this is, it is the only graph with the slope of 1/3

You figure this out by starting from the origin and counting up until the next place where the line connects with two lines of the grid, then you count across to that cross point

It's known as counting the rise over run

I hope I explained that well, it was pretty bad but I hope this helped

Answer: 6 2/25

Step-by-step explanation:

8/100 + 6

6= 6/1

6/1 + 8/100= 6 6/25 = 6.08

Answer:

6.08

Step-by-step explanation:

1. 1 hundredth is equal to 0.01 because it's 1 unit of out 100.

2. 1 whole is equal to 1 because it's just one, whole unit.

3. Given this information, 8 hundredths would be 0.08 and 6 wholes would be 6.

4. Now, to find the sum, just add these two numbers together:

Therefore, the answer is 6.08.

Answer:

you subtracted 2y from both sides to each side getting 2y = 10x +8

Step-by-step explanation

Step-by-step explanation:

10x was added to both sides which resulted in

2y = 10x + 8

now divide both sides by 2

y = 5x + 4

The slope is 5 and the y intercept is (0,4)

Answer:

y = 122

Step-by-step explanation:

let us start by adding some angles ourselves.

we are going to add angles at the right side of 150 and at the left of y

we can call the angle beside 151 x and the angle beside y A

first of all, let us find the value of x

now, angles 151 and x add up to 180 because angles on a straight line add up to 180 and the two angle are on a straight line of their own

which means;

151 + x = 180

when we collect like terms,

x = 180 - 151

x = 29

therefore, our x = 29

next, we find A

now, angles 29 ( our x ), 93 and our A all add up to 180 because the sum of angles in a triangle is 180 and our angles are in a triangle ( at least an upside down one with lines shooting out from every end )

that is;

29 + 93 + A = 180

collect like terms

A = 180 - 29 - 93

A = 180 - 122

A = 58

so, now that we have our angle A, the next thing to do is the same thing we did to get angle x,

we can see that A and y are both on a straight line of their own which means that they both add up to 180 degrees

that is;

A + y = 180

and we know that A = 58

so;

58 + y = 180

we collect like terms to have

y = 180 - 58

y = 122

therefore, y = 122

if you might have noticed, y is the same as x and 93

and that is correct because according to a rule in math, the value of an exterior angle of a triangle is equal to the sum of its opposite interior angles of the triangle. this can be explained using our question above

Answer:

9 nickels dude its soo easy.

Step-by-step explanation:

Answer:

9 nickles

Step-by-step explanation:

3 dimes is 30 cents

42 pennies is 42 cents

9 nickles is 45 cents

it's the fourth option

what you need to do is convert them all to a decimal and compare them to see which one applies :)

decimal form:

3.14, 2.70, 2.28

The expression [tex]2.4 \times 7[/tex] can be estimated by [tex]2 \times 7[/tex], so the answer would be roughly 14 here. I'm not sure where you got that '1' from.

Directly below that problem, we have the expression [tex]63.2 \times 0.78[/tex] which can be estimated by computing [tex]63 \times 1[/tex] which simplifies to 63. The '1' is from rounding to the nearest whole number.

Other than that, everything else looks correct on your worksheet.

Answer:

[tex]\displaystyle k = 20[/tex]

Step-by-step explanation:

We are given the function:

[tex]\displaystyle f(x) = 3x^3 - 2x + k[/tex]

Where (x + 2) is a factor of f. And we want to determine the vale of k.

Recall that from the Factor Theorem, if (x - a) is a factor of a polynomial P(x), then P(a) must equal 0.

We can rewrite our factor as (x - (-2)). Hence, a = -2. Our polynomial is f. Since (x + 2) is a factor, then from the Factor Theorem, f(-2) must be 0.

Using this information, we can now determine k:

[tex]\displaystyle\begin{aligned} f(x) & = 3x^3 -2x + k \\ \\ f(-2) = 0 & = 3(-2)^3 -2(-2) + k \\ \\ 0 & = (-24) + (4) + k \\ \\ k & = 20 \end{aligned}[/tex]

In conclusion, the value of k is 20.

Angle bisector theorem

Similarity theorem

As per the given condition m ∠LOM = m ∠JKI, m ∠MON = m ∠IKH it is proved that m ∠LON = m ∠HKJ as they are congruent angles.

"Congruent angles is defined as the angles with equal measure."

According to the question,

In the given figure of the angles,

m ∠LOM = m ∠JKI  (given congruent angles)                     _____(1)

m ∠MON = m ∠IKH  (given congruent angles)                  _______(2)

Add both the side angle  m ∠MON in (1) we get ,

m ∠LOM + m ∠MON = m ∠JKI + m ∠MON

Replace angle  m ∠MON = m ∠IKH from (2)  on right hand side we get,

m ∠LOM + m ∠MON = m ∠JKI + m ∠IKH      ____(3)

m ∠LOM + m ∠MON = m ∠LON  ( M is the interior point of ∠LON)    ___(4)

m ∠JKI + m ∠IKH = m ∠HKJ  ( I is the interior point of ∠HKJ)            ___(5)

Form (3) , (4) and (5) we get,

m ∠LON = m ∠HKJ  (Congruent angles)

Hence, form the given condition it is proved that m ∠LON = m ∠HKJ , are congruent angles.

Answer:

we have, 1953125=5⁹, so it cannot be a perfect square. If the last digit of a given number is 5, then the last three digits must be perfect squares, 025 or 225 or 625. Otherwise, that number cannot be a perfect square. And as 125 is not a perfect square, so no number ending with 125 can be a perfect square

Answer: The vector relies on how the objects of where the magnitude and directions should lay on.

Step-by-step explanation:

So, I’ll help you with these 4 problems. So, for the vector 2/4, it would 2 units up and 4 units to the right. The second would be 5 units down and 6 units to the right. The third one would be 3 units up and 1 unit to the left. The last one would be 10 units downs and 12 units to the left. A simplified way of thinking of this is to just look at the signs of the number and see where the vector’s magnitude and directions would go in that point of view when you visual the graph or count it in your head.
