Answer:

y=7 and x=-8

Step-by-step explanation:

Isolate x in the first equation:

10x=-17-9y

x=(-17-9y)/10

Substitute into the second equation:

7*((-17-9y)/`10)+10y=14

-119/10+37y/10=14

-119+37y=140

37y=259

y=7

Putting this into the first equation, we get that x=-8

Answer:

#7 can be simplified to -10 √15x -40 √5

#8 = -20 √6x +30x√2

#9 = 10x√6+3 √15xx

#10 = -20√6a -15 √2

Answer:

In technical terms, the slope of the line is the change in y over the change in x. But I just like to think of it as rise overrun. To find the slope of the line, pick two points on the line. Let's say we've looked at our graph, and have picked the points (3, 2) and (5, 6).

Step-by-step explanation:

Asymptote is the x axis for both functions. the y intercept is translated up to 125

A relation is a function if it has only One y-value for each x-value.

The asymptote and intercept of the given function compare to the asymptote and intercept of the function f(x) = 5ˣ

To find x- or y-intercepts, set the other variable equal to zero and solve in turn.

To find y-intercept: set x = 0 and solve for y. The point will be (0, y). To find x-intercept: set y = 0 and solve for x. The point will be (x, 0).

The asymptote is the x axis for both functions. the y intercept is translated up to 125.

Hence, asymptote is the x axis for both functions. the y intercept is translated up to 125.

Answer: x is less than or equal to 29.40

The minimum quantity of paperbacks you must purchase to receive a discount is represented by an inequality where x is less than or equal to 29.40.

A connection that compares two numbers or other mathematical expressions inequitably is known as an inequality in mathematics. On the number line, size comparisons between two numbers are typically conducted.

A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics.

Mathematicians utilize the greater than symbol, less than symbol , less than symbol, and not equal to symbol as the five inequality symbols.

Take from each side the same quantity. To both sides, add the same positive number. Add the identical positive value to both sides. Then, multiply both sides by the same negative number while flipping the sign.

Step-by-step explanation:

Answer:

first option

Step-by-step explanation:

Using the rule of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] then

[tex]5^4)^{3}[/tex] = [tex]5^{4(3)}[/tex] = [tex]5^{12}[/tex]

Answer:

The height of the light pole to the nearest foot is approximately 50 feet

Step-by-step explanation:

The parameters given in the question are;

The length of the cable = 63 feet

The angle of elevation of the cable to the top of the light pole = 52°

With the assumption that the light pole is perpendicular to the ground, the figure formed by the light pole, the distance of the of the cable from the base of the light pole and the length of the cable form a right triangle

The question can be answered by using trigonometric relations for the sine of the given angle as follows;

[tex]sin ( \theta) = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

The opposite leg length of the formed right triangle = The height of the light pole

The hypotenuse length = The length of the cable = 63 feet

The angle, θ = The angle of elevation = 52°

Plugging in the values, gives;

[tex]sin (52 ^ {\circ}) = \dfrac{The \ height \ of \ the \ light \ pole }{63 \ feet}[/tex]

∴ The height of the light pole = 63 feet × sin(52°) ≈ 49.645 feet

The height of the light pole to the nearest foot ≈ 50 feet.

Answer:

25[tex]\pi[/tex]

Step-by-step explanation:

Use the area formula, A = [tex]\pi[/tex]r²

Plug in 10 as the radius:

A = [tex]\pi[/tex](10²)

A = 100[tex]\pi[/tex]

Since it is a 1/4 circle, divide this by 4:

100[tex]\pi[/tex]/4

= 25[tex]\pi[/tex]

So, the area is 25[tex]\pi[/tex] or approximately 78.54

Answer:

12.96c

Step-by-step explanation:

Given the total cost of an item  written as c+0.08c. To get the total cost of an item that sells for 12, we will write;

1 item = c+0.08c

1 item = 1.08c

For 12items;

12 = x

Divide both expressions

1/12 = 1.08c/x

1 * x = 12 * 1.08c

x= 12.96c

Hence the total cost of 212 items is 12.96c

Answer:

y = 7, x ≈ 9.9

Step-by-step explanation:

The remaining angle has to also be 45° which tells us we're working with an isosceles right triangle, or that y also has to be 7 (the same length).

Use the Pythagorean theorem for x.

a^2 + b^2 = x^2

7^2 + 7^2 = x^2

49 + 49 = x^2

x^2 = 98

x ≈ 9.9

Answer:

the second one.... ( 8,9 )

Step-by-step explanation:

the zero-product system is rlly easy to use....

it basically means to take each term and equal it to zero....

so for your equation it is....

( x - 9 ) ( x - 8 ) = 0

so you would write it as....

( x - 9 ) = 0

and

( x - 8 ) = 0

and then you solve them like this...

( x - 9 ) = 0

add 9 to both sides to get the variable by itself...

x= 9

( x - 8 ) = 0

add 8 to both sides to get the variable by itself....

x = 8

Given:

CDEF is a rhombus.

To find:

The value of x.

Solution:

We know that the diagonals of a rhombus are angle bisectors because they bisect each vertex angle.

[tex]5x+1=8x-20[/tex]

[tex]5x-8x=-1-20[/tex]

[tex]-3x=-21[/tex]

Divide both sides by -3.

[tex]x=\dfrac{-21}{-3}[/tex]

[tex]x=7[/tex]

Therefore, the value of x is 7.
