Answer:

6 (x)

Step-by-step explanation:

Answer:

x² + 5x + 6 = 0

Step-by-step explanation:

The zeros of quadratic function is (- 3) and (- 2)

The coordinates of vertex are (- 2.5, -0.25)  

(x + 3)(x + 2) = 0

x² + 5x + 6 = 0

Answer:

negative

Step-by-step explanation:

Positive numbers do not change the polarity of a number in multiplication, only negative numbers.

Answer:

Slope, b = 1.38 ; intercept, a = - 0.56 ;

Y = - 0.56 + 1.38x

Step-by-step explanation:

Given that :

xbar = 12

ybar = 16

r = .46

Sy = 18

Sx = 6

The equation of a line can be expressed as :

Y = a + bx

Where ;

a = intercept ; b = slope ; x = independent variable ; y = dependent variable

The slope b ; can be obtained using the relation :

b = r(Sy / Sx)

= 0.46(18/6)

= 0.46(3)

= 1.38

The intercept a, can be obtained using the relation :

Ybar - b(Xbar)

16 - 1.38(12)

16 - 16.56

a = - 0.56

Hence ;

Slope, b = 1.38 ; intercept, a = - 0.56

Th equation of the line will be :

Y = - 0.56 + 1.38x

Answer:

x = [tex]133\frac{1}{3}[/tex] of y

Step-by-step explanation:

Given:

15% of x equals 20% of y

So,

0.15x = 0.20y

so

x = 0.20 y / 0.15

x = 1.3333y

x = [tex]133\frac{1}{3}[/tex] of y

Answer:

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

So to find slope you just subtract y^1 - y^2 and divide it by x^1 - x^2

The first point is (2, 1)

The second is (0, 5)

1 is our y^1 and 5 is our y^2

1 - 5 = -4

2 is our x^1 and 0 is our x^2

2 - 0 = 2

So our slope is -4/2, reduced its -2

Answer: y=1/3x+1

Y needs to be changed in order to maintain parallelism.

Good Luck!

Answer:

The answer is y=1/3x+1

Step-by-step explanation:

y=mx+b

m=1/3

y-y=m(x-x1)

y-2=1/3(x-3)

y-2= 1/3x-1

+2 +2

y=1/3x+1

Answer:

-6 is the x-coordinate value

Step-by-step explanation:

Mathematically, slope can be calculated as;

m = (y2-y1)/(x2-x1)

For the value of the slope to be undefined, it means that we are actually dividing by zero

For us to be dividing by zero, it actually means that there is no change in the x-value

The unchanging x-value is what has caused us to have an undefined slope value

Since line k and line g are parallel, their slopes are equal and the slope of k is undefined too

So the x-coordinates of the other points that lie on the line that we used in calculating the slope is -6

Answer:

Step 3: He should have divided both sides by −7

Step-by-step explanation:

Incorrect calculation

−7x + 25 = 48

Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23

Step 3: negative seven times x over seven = twenty-three over seven

-7*x/7 = 23/7

-7x/7 = 23/7

Step 4: x = twenty-three over seven

Correct calculation

−7x + 25 = 48

Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23

Step 3: negative seven times x over seven = twenty-three over seven

-7*x/-7 = 23/-7

-7x/-7 = 23/-7

Step 4: x = twenty-three over negative seven

x = -23/7

Answer:

Number 1 is 0.3

Number 2 is is choice 2

Answer:

In standard form 0.0325 is written as 0.0325

In scientific notation it is written as:

[tex]3.25^{ - 2} [/tex]

The standard form of 0.0325 is written as

[tex] = 3.25 \times {10}^{ - 2} [/tex]

Given:

0.0325

Writing in standard form means writing in scientific notation (power of be 10)

0.0325

The decimal point will be moved 2 times before it gets between the be significant value of 3 and 2

Therefore,

0.0325

[tex] = 3.25 \times {10}^{ - 2} [/tex]

Answer:

  D. $40 with 25% discount

Step-by-step explanation:

All of the options have 8% sales tax, so that is not important to choosing the best deal.

The store with the lowest price after discount is D (local shoe store #2), as the discount brings the price down to $30 before tax.

The price at store C (local shoe store #1) will be 15% less than $38.00, so about $5.70 less. That is not as low a price as at store D.

The best buy is had at store D.

__

In the spreadsheet, we have multiplied the base price by (1+discount) then added shipping. That total is multiplied by (1+tax rate).

Answer:

There were 140 robberies in Springfield in 2012.

Step-by-step explanation:

Let's marked (named) robberies in 2012 with x, which is worth 100%

196 robberies in 2013 worth 100% + 40% = 140%

Now we will make proportion

x : 196 = 100 : 140

When we multiply external and internal members we get

140 x = 196 · 100 => 140 x = 19600 => x = 19600/140 = 140

x = 140 robberies in 2012

Answer:

242

Step-by-step explanation:

165 ÷ 15 = 110

110 × 2.2 = 242

The distance that trains travel in 2.2 hours with the same ratio or same speed will be 242 km.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

A train covers 165 km in 1.5 hours.

The ratio of distance covered to the number of hours is 165/1.5.

Let's say in 2.2-hour train travel x number of km.

The ratio of distance covered to the number of hours x/2.2

Both ratios must be the same,

x/2.2 = 165/1.5

x = 110 x 2.2 = 242 km

Hence "The distance that trains travel in 2.2 hours with the same ratio or same speed will be 242 km".

Answer:

Sorry I know the answer but it won't let me type it the right way

Step-by-step explanation:

Answer:

29

Step-by-step explanation:

(x+12) + 100 + x = 180

           2x + 112 = 180

Subtract 112 from both sides

                    2x = 58

Divide 2 from both sides

                      x = 29

Hi!

I'm assuming the question means what integers, so let's figure it out.

Starting from 12, 12 squared is 144, or the square root of 144 is 12.

13 squared is 169, or the square root of 169 is 13.

14 squared is 196, or the square root of 196 is 14.

15 squared is 225, or the square root of 225 is 15.

Based on that list of numbers, we can determine that the square root of 199 lies between the square root of 196 and the square root of 225 -- aka 14 and 15.
