Answer:

x = 9.7

Step-by-step explanation:

2.7x -9 = x +7.5

2.7x - x = 7.5 + 9

1.7x = 16.5

x = 16.5/1.7

x = 9.7

Answer:

x = 9.70588

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

2.7x - 9 = x + 7.5

Step 2: Solve for x

Step 3: Check

Substitute in x into the original equation to verify it's a solution.

Here we see that 17.2059 does indeed equal 17.2059.

∴ x = 9.70588 is a solution of the equation.

Answer: see explanation

Step-by-step explanation: To determine which ordered pairs satisfy the equation substitute the x coordinate of the point into the right side and if the value obtained equals the y coordinate of the point then it satisfies the equation

(- 1, - 1)

x = - 1 : y = - 4 + 3 = - 1 ⇒ (- 1, - 1) satisfies the equation

(2, 11)

x = 2 : y = 8 + 3 = 11 ⇒ (2, 11) satisfies the equation

(4, 7)

x = 4 : y = 16 + 3 = 19 ≠ 7 ⇒ (4, 7) does not satisfy the equation

(7, 1)

x = 7 : y = 28 + 3 = 31 ≠ 1 ⇒ (7, 1) does not satisfy the equation

[tex]h(x)=-1/2(x - 4)^2 + 3[/tex]

The domain is all real numbers.

The range is all real numbers [tex]\leq 3[/tex].

The domain of the function will be all real numbers and the range of the function will be (-∞, 3].

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient. Then the equation of the parabola will be given as,

y = a(x - h)² + k

The domain means all the possible values of x and the range means all the possible values of y.

The equation of the parabola is given below.

h(x) = – 1/2(x – 4)² + 3

The vertex of the parabola is at (4, 3). The parabola is a downward parabola.

The domain of the function will be all real numbers and the range of the function will be (-∞, 3].

More about the equation of the parabola link is given below.

y= mx+b

Where "y" is intercept

m= slope

b= constant= 20$ start up fee

Then writing the equation of slope for the question we have y=5x+20 which represent the slope equation.

The expression equivalent to [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex]  is  [tex]18x^{3}\sqrt{7x}[/tex].

In order to simplify an expression, multiple processes must be used to reduce it to a simpler form.

[tex]\sqrt[n]{ab} =\sqrt[n]{a} .\sqrt[n]{b}[/tex]

= [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex]

= [tex]5x\sqrt{4*7x^{5} } + 8x^{3} \sqrt{7x}[/tex]

= [tex]5x\sqrt{2^{2} *7x^{4}x } + 8x^{3} \sqrt{7x}[/tex]

Apply the simplification formula

= [tex]5x\sqrt{2^{2}} \sqrt{x^{4} } \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]

= [tex]5x*2x^{2} \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]

Further solve,

Answer:

The second statement is the contrapositive of the first.

Step-by-step explanation:

We know that x → y is a conditional statement read as 'if x then q'.

The converse EXCHANGES the hypothesis and conclusion such as:

y → x

The 'contrapositive' statement basically NEGATES the converse of the conditional such as:

¬y → ¬x

Coming back towards the question,

Given

x ⇒ y

¬y ⇒ ¬x

Therefore, the second statement is the contrapositive of the first.

Answer:

AT=6, RC=5

Step-by-step explanation:

Perpendicular bisector intersect at T that is the circumcenter.

since RT is a bisector or AC and AR=5 then RC=5

Circumcenter is equidistant from the vercices of the triangle so

AT≅BT≅CT

but CT is given to be CT=6 so AT=6

Answer:

AT=6, RC=5

Answer:

Undefined.

Step-by-step explanation:

m = y2-y1 / x2-x1

m = 3 - 2 / 1 - 1

m = 1/0, which is undefined.

You can also tell because (1,2) and (1,3) is a vertical line, which means the slope is undefined.

Answer:

36, 8.5

Step-by-step explanation:

an exponent of two means that you are multiply a number by itself

so in this case you would multiply 6 by itself: 6 x 6

this gets you 36

and 8.5 doesn't change so its just 8.5

Answer: One hosta= $8

One shrub = $10

Step-by-step explanation:

Let the cost of one hostas be h

Let th cost of one shrub be s.

The question can be rewritten into am equation as:

2h + 7s = 86 .......... equation i

8h + 4s = 104 ........ equation ii

Multiply equation i by 8

Multiply equation ii by 2

16h + 56s = 688 ...... equation iii

16h + 8s = 208 ........ equation iv

Subtract equation iv from iii

48s = 480

s = 480/48

s = 10

One shrub cost $10

Put the value of one shrub into equation ii

8h + 4s = 104

8h + 4(10) = 104

8h + 40 = 104

8h = 104 - 40

8h = 64

h = 64/8

h = $8

One hostas cost $8

Step-by-step explanation:

Hi there!

[tex]\large\boxed{\left \{ {{y=3x + 1} \atop {y = 3x - 1}} \right}[/tex]

From the graph, we can see that both lines are parallel. We can determine the slope of one line to find the slope of the other.

Use the slope formula to determine the slope of a line. In this case, I am using the blue line as a reference:

[tex]\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }[/tex]

[tex]m = \frac{ 3 - 1 } { 1 - 0 } = 3[/tex]

The slope of both lines is 3.

Let's find the equation of the blue line by finding its y-intercept to solve for the "b" value in the equation y= mx + b:

y-intercept is when x = 0, or at (0, 1). Therefore:

Blue line equation: y = 3x + 1

The red line intersects the y-axis at (0, -1), therefore:

Red line equation: y = 3x - 1

The systems of equations is:

y = 3x + 1

y = 3x - 1

Answer:

y = 2x + 1

y= 2x - 1
