D 12

Answer:

y = -14

Step-by-step explanation:

6 + y = -8

Subtract 6 from both sides to get y by itself.

y = -14.

Proof:

6 + y = -8

Substitute the variable.

6 + (-14) = -8

Add the negative/Subtract.

-8 = -8.

Answer:

y=−14

Step-by-step explanation:

Let's solve your equation step-by-step.

6+y=−8

Step 1: Simplify both sides of the equation.

y+6=−8

Step 2: Subtract 6 from both sides.

y+6−6=−8−6

y=−14

Let's find the slope of the line passing through it :

[tex] \boxed{ slope = \frac{y_2-y_1}{ x_2- x_1} }[/tex]

Now, we know, equation of a line is :

[tex]\longrightarrow y = mx + b[/tex]

where,

Therefore,

[tex]\longrightarrow \: y = \dfrac{1}{5} x + b[/tex]

let's put the value of x and y from the first coordinates .

Hence, we got the equation of line as :

Answer:

DF) = 10

AB) = 5

EF) = 12.5

Step-by-step explanation:

For length AB

[tex]3^{2} +4^{2} = AB^{2}[/tex]   -> 9+16=[tex]\sqrt{25}[/tex] -> 5

For length DF

We know that AD is 2.5 times smaller than DE (7.5 / 3)

Now we can use that to determine length DF

BD = 4, DF = 4*2.5 = 10

using the Pythagorean theorem, you can find EF:

[tex]DE^{2} +DF^{2} =EF^{2}[/tex]

[tex]7.5^{2}+ 10^{2} =12.5[/tex]

Answer:

42 < x less than or equal to 57

Step-by-step explanation:

The inequality that would model the height, x, required for this amusement park ride is 57 > h > 42.

A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations

Now it is given that,

Lower limit of height must be greater than 42 inches

Upper limit  of height must be less than 57 inches

If h is the height used for model.

Thus, h < 57 inches

and, h > 42 inches

Therefore the inequality model will be,

57 > h > 42

Thus, the inequality that would model the height, x, required for this amusement park ride is 57 > h > 42.

Answer:

PART A

PART B

total cost =12.325+8.24

hope it helps

Answer:

Part A: $12.325

Part B: $20.565

Step-by-step explanation:

PART A:

To find the answer, we multiply 2.9 and 4.25 together: 2.9 * 4.25 = 12.325

The cost of 2.9 pounds of dark chocolate is $12.325

PART B:

To find the answer, we multiply 1.6 and 5.15 together: 1.6 * 5.15 = 8.24

After that, to find the cost of the dark and milk chocolate together, we add up the two answers: 12.325 + 8.24 = 20.565

The total cost of the milk and dark chocolate is $20.565

Note: You might need to round it up. In this case, Part A is $12.33 and Part B is $20.57

Answer:

x-intercept: -4

y-intercept: 24/5

Step-by-step explanation:

Firstly you have to isolate the y:

-6x + 5y = 24

5y = 6x + 24

y = (6x +24)/5

Now, just think about the graph: when the function touch the x-axis, the value of y is equal to 0, and when the function touch the y-axis, the value of x is 0, so just put they in the function:

y = (6•0 + 24)/5

y = 24/5

0 = (6x + 24)/5

5•0 = 6x +24

0 = 6x +24

-6x = 24

x = 24/-6

x = -4

Answer:

70

Step-by-step explanation:

(Not the most streamlined way but.)

Knowing that if he had 5 tests, and a mark of 85, we can determine the total average grade Bill received. 85*5=425

Then subtract the known grades

425-(90+85+100+80)=x

425-(355)=x

70=x

Bill would have scored 70 on that 5th test

Answer:

2466.67

Step-by-step explanation:

1850/.75=2466.67

The cost of selling price of the computer is, $3,237.5

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Cost of the computer = $1,850.00

Markup = 75%

Now,

The cost of selling price of the computer is,

⇒ $1,850 + 75% of $1,850

⇒ $1850 + 75 /100 × $1850

⇒ $1850 + $1387.5

⇒ $3,237.5

Answer:

1) 2 nonreal complex roots

2) 1 Real Solution

3) 16

4) Reflected, narrower by a factor of 2/5, slides right 4 units and slides up 6 (units)

Step-by-step explanation:

1) The graph does not intercept the x-axis, therefore, there are no real solutions at the point y = 0

We get;

y = a·x² + b·x + c

At y = 6, x = -2

Therefore;

6 = a·(-2)² - 2·b + c = 4·a - 2·b + c

6 = 4·a - 2·b + c...(1)

At y = 8, x = 0

8 = a·(0)² + b·0 + c

∴ c = 8...(2)

Similarly, we have;

At y = 8, x = -4

8 = a·(-4)² - 4·b + c = 16·a - 4·b + 8

16·a - 4·b = 0

∴ b = 16·a/4 = 4·a

b = 4·a...(3)

From equation (1), (2) and (3), we have;

6 = 4·a - 2·b + c

∴ 6 = b - 2·b + 8 = -b + 8

6 - 8 = -b

∴ -b = -2

b = 2

b = 4·a

∴ a = b/4 = 2/4 = 1/2

The equation is therefor;

y = (1/2)·x² + 2·x + 8

Solving we get;

x = (-2 ± √(2² - 4 × (1/2) × 8))/(2 × (1/2))

x =( -2 ± √(-12))/1 = -2 ± √(-12)

Therefore, we have;

2 nonreal complex roots

2) Give that the graph of the function touches the x-axis once, we have;

1 Real Solution

3) The given function is f(x) = 2·x² + 8·x + 6

The general form of the quadratic function is f(x) = a·x² + b·x + c

Comparing, we have;

a = 2, b = 8, c = 6

The discriminant of the function, D = b² - 4·a·c, therefore, for the function, we have;

D = 8² - 4 × 2 × 6 = 16

The discriminant of the function, D = 16

4.) The given function is g(x) = (-2/5)·(x - 4)² + 6

The parent function of a quadratic equation is y = x²

A vertical translation is given by the following equation;

y = f(x) + b

A horizontal to the right by 'a' translation is given by an equation of the form; y = f(x - a)

A vertical reflection is given by an equation of the form; y = -f(x) = -x²

A narrowing is given by an equation of the form; y = b·f(x), where b < 1

Therefore, the transformations of g(x) from the parent function are;

g(x) is a reflection of the parent function, with the graph of g(x) being narrower by 2/5 than the graph of the parent function. The graph of g(x) is shifted right by 4 units and is then slides up by 6 units.
