I dont really know what to do here, ive done a which is -2 but dont know how to do b. It is not 1/2x -1.5

Answer:

D

Step-by-step explanation:

Consecutive integers are integers with the progression n, n+1, n+2 (EXAMPLE)

Since w, x, y are consecutive integers, that means w, w+1, w+2; x = w+1, y = w+2

By referring to D,

w + x + y = w + w+1 + w+2

= 3w + 3

Hence, D is true.

Answer:

D

Step-by-step explanation:

A is wrong because if w is -1, x is 0, and y is 1, then wy is negative.

B is wrong because if w is -1, x is 0, and y is 1, then -1 + 1 = 0, which is x.

C is wrong because if w is -1, x is 0, and y is 1, then w³ + 3 = -1 + 3 = 2, which is greater than w + x + y which is 0.

D is correct because w + x + y is always equal to 3w + 3. For example, if w is 1, x is 2, and y is 3, then w + x + y = 6. 3w + 3 = 3(1) + 3 = 6.

E is wrong because if w is 1, x is 2, and y is 3, then wx is 2 and xy is 6, which means xy is greater than wx.

Answer:

#1: 4) D

#2: 1) 34.89 = 3 × C

#3: 4) 6y + 18

Step-by-step explanation:

#1

Using the distributive property:

3 × 5z = 15z

3 × -3 = -9

The correct expression is 15z - 9. Hence, D is the right option.

#2

You need to find the cost of each box.

3 × C = 34.89

34.89 ÷ 3 = 11.63

3 × 11.63 = 34.89

Hence, 1) is the right option.

#3

Using the distributive property:

6 × y = 6y

6 × 3 = 18

The expression is 6y + 18. Hence, 4) is the right option.

hope this helps!! p.s. i really need brainliest :)

Answer:

1. #4, D

2. #1, 34.89 = 3 x c

3. #4, 6y + 18

Step-by-step explanation:

1. Which pair of expression are equivalent (=)?

A.

10c + 20 = 5(5c + 4) <== distribute

10c + 20 = 25c + 20

This pair is not equivalent

B.

3(4e -  2) = 7e - 5 <== distribute

12e - 6 = 7e - 5

This pair is not equivalent

C.

4(4h + 6) = 16 + 24 <== distribute

16h + 24 = 16 + 24

This pair is not equivalent (look carefully, it's missing an h)

D.

15z - 9 = 3(5z - 3) <== distribute

15 - 9 = 15z - 3

This pair is equivalent

Therefore, the correct answer is D

2. Mr. James bought 3 boxes of pencils for $34.89. Each box of pencils costs the same. Which equaiton can be used to find the cost, c, of each box?

We know that 3 boxes of pecils cost $34.89, and c represents the cost of one box. If c represents the cost of one box and there are 3 boxes, it would be 3c or 3 x c.

Looking at the answer choices, #1 is the only option that represents that.

Therefore, the correct answer is 1) 34.89 = 3 x c

3. Aidan wrote an expression 6(y + 3). Which expression is equivalent to the one Aidan wrote?

Answer:

-x + 1

Step-by-step explanation:

f(x) = 2x + 3

g(x) = 3x + 2

we want to find (f-g)(x)

(f-g)(x) is the same as saying f(x) - g(x)

f(x) - g(x) = (2x + 3) - (3x + 2)

==> remove parenthesis and apply negative sign

f(x) - g(x) = 2x + 3 - 3x - 2

==> combine like terms

f(x) - g(x) = -x + 1

Answer:

  (a)  Shapes with perpendicular sides and shapes without perpendicular sides

Step-by-step explanation:

This appears to be a reading comprehension problem, along with a requirement that you recognize squares and rectangles have right angles and pairs of parallel equal-length sides.

__

The group descriptions are very careful to say that the members of Group B have no right angles. Members of both groups have equal-length sides and parallel lines, so those are not distinguishing criteria.

The relevant attribute for sorting appears to be right angles/no right angles.

Answer:

$724.11

Step-by-step explanation:

This requires the use of the growth formula.

Growth Formula:

[tex]y = a*(1+r)^x[/tex]

y = total/answer

a = starting value

r = rate (1.25 = 25%)

x = the amount of time (years/months)

Equation:

[tex]y = 6200 * (1+0.028)^4[/tex]

Solving:

y = $6924.11

$6924.11 - $6200 =  total interest

$724.11

[tex]~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$6200\\ r=rate\to 2.8\%\to \frac{2.8}{100}\dotfill &0.028\\ t=years\dotfill &4 \end{cases} \\\\\\ I = (6200)(0.028)(4)\implies I=694.4[/tex]

Answer:

Step-by-step explanation:

When the base of a logarithm is not specified, it is assumed that the base is 10. Therefore we have:

[tex]log_1_0(x^2-15)=log_1_0(2x)[/tex]

Intuitively you can see that if the two arguments inside of the logarithm equal each other, then both sides will be equal to each other. Therefore, you can say the following requirement:

[tex]x^2-15=2x[/tex]

Subtract 2x on both sides to get:

[tex]x^2-2x-15=0[/tex]

Use the quadratic formula to solve for 'x' to get:

[tex]x=(-b+\sqrt{b^2-4ac} )/2a[/tex]

[tex]x=(-b-\sqrt{b^2-4ac} )/2a[/tex]

Beginning with the first solution:

[tex]x=(-(-2)+\sqrt{(-2)^2-4(1)(-15)} )/2(1)[/tex]

[tex]x=2+\sqrt{4+60} )/2[/tex]

[tex]x=(2+\sqrt{64}) /2[/tex]

[tex]x=(2+8)/2[/tex]

[tex]x=5[/tex]

Second solution:

[tex]x=(-(-2)-\sqrt{(-2)^2-4(1)(-15)} )/2(1)[/tex]

[tex]x=(2-\sqrt{4+60} )/2[/tex]

[tex]x=(2-8)/2[/tex]

[tex]x=-6/2[/tex]

[tex]x=-3[/tex]

Since the 'x' value inside of the logarith is squared, the -3 is a valid solution. Ordinarily, the log function cannot take on negative values.

Answer:

more likely

Step-by-step explanation:

3/4 is 0.75 or 75%. I would describe it as likely.

3/4 is not equal to 1 or 0.5 or 0. It is also not equal to 0.25

The total number of balls in a bag will be 4 in which 3 balls are red and 1 ball is blue.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

The probability of the event is 3/4.

Let the total number of balls be 4 of two colors that are red and blue and the probability of red color be 3/4.

There will be a total of 4 balls in the bag, 3 of which will be red and 1 blue.

[tex]y = 6x - 2[/tex]

I believe this is correct

Answer:

y = 2x + 1

Step-by-step explanation:

You can see a pattern in the group of x's that the numbers go up by 1 Also in the y-set that the numbers go up by 2. So this pattern is linear, that means the "rule" you are looking for does not have exponents or square roots or any very complicated stuff. You can use a guess and check method. Say to yourself how can I get a 7 out, when I put a 3 in? "times by2 and plus 1" works.

3 times 2, and plus1

gives you 7.

Test it on the other numbers.

-1 times2, and plus1

2(-1)+1 = -1

2(0)+1 = 1

2(1)+1 = 3

2(2)+1 = 5

It works for all the numbers.

You can calculate it also, using any two pairs of (x,y) from the data set. Put y-y on top of a fraction and x-x on the bottom. You will get the slope and that is the 2 in the "rule"

(3,7) and (2,5) for example. 7-5 so put 2 on top and 3-2 so put 1 on the bottom. 2/1 is just 2. From the point (0,1) we know the y-intercept is 1. This also gives the equation y=2x+1.

If you are just starting to learn this, probably just guess and check a rule. The rule has to work for all the points.

Step-by-step explanation:

Where x = 1.01,  y = (1.01)^4 + 1 = 1.0406 + 1

= 2.0406

So the gradient between (1, 2) and (1.01, 2.0406)

Using relations in a right triangle, it is found that it's area is of 302.2 units squared.

The relations in a right triangle are given as follows:

In this problem, we have that the opposite side to the angle of 25º is of x, while the adjacent side is of 36, hence:

[tex]\tan{25^\circ} = \frac{x}{36}[/tex]

[tex]x = 36\tan{25^\circ}[/tex]

x = 16.79.

It is given by half the multiplication of it's sides, hence:

A = 0.5 x 16.79 x 36 = 302.2 units squared.
