the answer is 4

a+(-7)+3=0

a=7-3

a= 4

Answer 2

Answer:

4

Step-by-step explanation:

There are two ways of going about this problem. One could simply substitute every given answer and simplify to see if it makes a true statement. Conversely, one could solve the given equation with inverse operations. In this case, it is easier to solve with inverse operations.

Undo parenthesis,

a + (-7) + 3 = 0

a - 7 + 3 = 0

Simplify,

a - 7 + 3 = 0

a - 4 = 0

Inverse operations,

a - 4 = 0

Then it would be the other way around 19 ≥ k + 6

Wait for more responses if needed.

The given Inequality is correct when 19 ≥ k + 6.

What is inequality?

Inequality compares "two values, showing if one is less than, greater than, or simply not equal to another one".

Given k + 6 ≥ 19 if k = 11

11 + 6 ≥ 19  substitute k = 11

17 ≥ 19 here Inequality is False.

Hence, 19 ≥ k + 6.

Next time, the rabbit from the previous problem start at 10 where on the number line can he be after the same three jumps?

Previous problem : A rabbit started at point 0 and made 3 jumps: a jump of 4 units, then a jump of 2 units, and then a jump of 1 unit. We do not know the direction of either jump. What are all the possible numbers can this rabbit be now?

Answers

It should be noted that since the rabbit from the previous problem started at 10, it would be at 17 units on the number line after the same three jumps.

What is a number line?

A number line is a type of graph with a graduated straight line which comprises both positive and negative numerical values. From the previous problem, the total distance covered by the rabbit is given by:

Total distance = 4 units + 2 units + 1 unit

Total distance = 7 units.

Since the second point is at 10 units and the open circle arrow points to the right of the number line, the rabbit would cover 7 more distance from this point:

Total distance = 10 units + 7 units

Total distance = 17 units.

Answer:

#5- 7.8 hours  #6- $5.25

Step-by-step explanation

Question #5- 7.8 hours      

First we have to find the speed. If the speed was constant we should be able to divide the miles by the time to find the speed. So 239.82 divided by 4.2. This would leave us with a speed of 57.1 mph. So to finish the question, we have to take  what we know and divided it by the speed. If he drives 445.38 miles at the same speed of 57.1 mph it would take him 7.8 hours. I got this answer by dividing the miles by the speed. 445.38 divided by 57.1. Which got us our time, 7.8 hours.

Question #6- $5.25

Okay so we know that the chips cost .75 cents a bag, and he got two bags. So if we take .75 and multiply it by two we get 1.50. So the chips alone cost $1.50. We can take the price of the chips and subtract it from the total price. 22.50-1.50. 21. Now we have just the prices of the sandwiches. If we take the total price of the sandwiches and divide it by the number of sandwiches bought, we get $5.25. So each sandwich cost $5.25 each.

The factored expression is?

Answers

Answer:

3 x -3y = -9y

3 x -1 = -3

The factored expression is 3(-3y - 1)

Step-by-step explanation:

All you have to do is -9y / 3 = -3y and -3 / 3 = -1, then put those numbers in parentheses. All of that is multiplied by 3.

The reason is because if you distributed the 3 it would become:

3 * -3y + 3 * -1 = -9y - 3


Three red,ten white, five blue and two green counters are put into a bag, and one is picked at random. Calculate the probability that it is:

i) a white counter

ii) a red counter

iii) Are the outcomes equally likely?

Answers

Answer:

(i) 1/2

(ii) 3/20

Step-by-step explanation:

(i) given total number of white counters = 10

total outcomes = 20 (3+10+5+2)

so it's 10/20

by simplifying it we get 1/2

(ii) given total number of red counters = 3

Answer:

first part: A. x^2+9x=36 and C. (x+9)(x)=36

second part: Width = 3 inches, Length = 12 inches

Step-by-step explanation:

"more than" implies addition, so you know you'll have 9+x in the equation you also know that you have to have the equation =36

also note (9+x is the length)

the equation for area of a rectangle is A=LW

so lets plug in what we do know

A = L W

36=(9+x)W

For the first part of the equation you're answer will be:

(x+9)(x)=36 AND x^2+9x (the reason for the second answer i listed is because when you multiple (x+9)(x) you get x^2+9x

when you solve for x it equals 3,

so the width (x) = 3 inches

and the Length (9+3) =12 inches

Answers

Answer: C. Distribute 3/4 over (x-8)

Step-by-step explanation:

To solve any(technically most, but still...) algebraic equation you must isolate the variable.  In this case, the first step would either be to divide both sides of the equation by 3/4, or distribute 3/4 to x and -8, as you cannot modify the contents of the parenthesis without removing the 3/4.

Quadratic equation

Answers

x=-3

x=-11

because

x(x+14)=-33

so if x = -11 it will be 3*-11

and if x= -3 it will be -3*11

Answer:

x = -3, -11

Step-by-step explanation:

First, factor

Get all the terms on one side by adding 33 to both sides:

[tex]x^2 + 14x + 33 = 0[/tex]

now, you want to find two numbers that add up to 14 and multiply to 33.

those numbers would be 3 and 11.

so you can then make it:

[tex](x + 3)(x+11)=0[/tex]

you know that either x + 3 or x + 11 = 0,

so you can say:

x + 3 = 0

x = -3

ork

x + 11 = 0

x = -11

so x = -3, -11.

First, the triangle is dilated by a scale factor of 1/3 about the origin. Then the triangle is reflected over the x-axis. Finally, the triangle is translated left 3 units and up 2 units.

Answers

Answer:

[tex](\frac{1}{3}x - 3,-\frac{1}{3}y+2)[/tex]

Both triangles will be similar

Step-by-step explanation:

See comment for complete question.

Given

Let the coordinates of the triangle be T(x,y)

First transformation: Dilation by 1/3

The new points will be:

[tex]T' = \frac{1}{3}(x,y)[/tex]

[tex]T' = (\frac{1}{3}x,\frac{1}{3}y)[/tex]

Second: Reflection over the x-axis

When a point (x,y) is reflected over the x-axis, the new point is (x,-y).

So, we have:

[tex]T'' = (\frac{1}{3}x,-\frac{1}{3}y)[/tex]

Third: Translation 3 units left and 2 units up.

When a point (x,y) is translated b units left and h units up, the new point is (x - b,y+h).

In this case:

[tex]b = 3[/tex] and [tex]h = 2[/tex]

So, we have:

[tex]T''' = (\frac{1}{3}x - 3,-\frac{1}{3}y+2)[/tex]

Hence, the coordinate of the new triangle will be: [tex](\frac{1}{3}x - 3,-\frac{1}{3}y+2)[/tex]

Additionally, both triangles will be similar because all the transformation done are rigid transformations i.e. Dilation, Reflection and Translation
