5x-9y=-26 and -2x+3y=11 combing the equations

Answer:

70°

Step-by-step explanation:

We know that the triangle is an iscoceles based on the 2 small lines drawn horizontally on 2 sides of the triangle.

We know that the base angles in an iscoceles triangle are the same, so the angle that has not been drawn is 55°.

55° + 55° = 110°

180° - 110° = 70° (180 comes from the entire triangle adding up to 180°)

Step-by-step explanation:

0 would be your answer

first you combine like terms and get 5a+4 on each side then you have to solve the equation.

Given:

The equations are

[tex]2x+5y=0[/tex]

[tex]3x-4y=23[/tex]

To find:

The solution of given system of equations.

Solution:

We have,

[tex]2x+5y=0[/tex]        ...(i)

[tex]3x-4y=23[/tex]       ...(ii)

From (i), we get

[tex]2x=-5y[/tex]

[tex]x=-\dfrac{5y}{2}[/tex]        ...(iii)

Putting this value in (ii), we get

[tex]3(-\dfrac{5y}{2})-4y=23[/tex]

[tex]-\dfrac{15y}{2}-4y=23[/tex]

[tex]\dfrac{-15y-8y}{2}=23[/tex]

[tex]-23y=2\times 23[/tex]

[tex]y=\dfrac{46}{-23}[/tex]

[tex]y=-2[/tex]

Putting y=-2 in (iii), we get

[tex]x=-\dfrac{5(-2)}{2}[/tex]

[tex]x=-\dfrac{-10}{2}[/tex]

[tex]x=\dfrac{10}{2}[/tex]

[tex]x=5[/tex]

Therefore, the solution of given system of equation is (5,-2).

Graphs are used to show the relationship between two variables (usually x and y). The values of x when [tex]f(x) = 0[/tex] are 2 and 8

The graph of y = f(x) is given

To get the values of x when [tex]f(x) = 0[/tex], we simply consider where the line of the graph crosses the x-axis.

The graph crosses the x-axis at:

[tex]x = 2[/tex]

[tex]x = 8[/tex]

This means that the values of x when [tex]f(x) = 0[/tex] are 2 and 8

Answer: 60 feet²

Step-by-step explanation:

The width of the rectangular room is 60% of the length which is 10 feet.

The width is therefore:

= 60% * 10

= 6 feet

The area of a rectangle is calculated by the formula:

= Length * Width

Area there is:

= 10 * 6

= 60 feet²

Answer:

y=x-1

Step-by-step explanation:

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

m=(-3-6)/(-2-7)

m=-9/-9

m=1

y-y1=m(x-x1)

y-6=1(x-7)

y-6=x-7

y=x-7+6

y=x-1

Answer: $432

Step-by-step explanation: If he marks up the price by 80% then you multiply the price (240) times 0.8, which is 192. That is how much he marks it up -- $192. SO then you add how much he marks it up to the original price of $242 which is $432.

The height of the cone is 1.6 ft.

A right circular cone is one whose axis is perpendicular to the plane of the base. We can generate a right cone by revolving a right triangle about one of its legs.

Given that, a right circular cone has a volume of 15 cubic feet and a radius of 3 feet, we need to find the height of the cone,

Volume of the cone = π × radius² × height / 3

15 × 3 = 3.14 × 3² × height

Height = 45 / 3.14 × 9

Height = 1.60

Hence, the height of the cone is 1.6 ft.

Answer:

The missing value of x in this arithmetic sequence is "1"

Step-by-step explanation:

Since this is an arithmetic sequence that means that when we get from one term to the next one we always add/substract the same number each time.

In our case each time we need to find the next term we just add 6 to the current term. For example, after 13 we have 19 which is essentially 13 + 6.  

From this we know in order to get from x to 7 we added 6, now know this we can make an equation...

x + 6 = 7

And now we just solve it...

x + 6 = 7

x = 7 - 6

x = 1

Answer:

180 degrees.

Step-by-step explanation:

The measure of angle EDC is equal to the sum of the angles of EDQ and QDC.

In  this problem, angle EDQ is equal to 30 degrees, and angle QDC is equal to 150 degrees.

So, angle EDC is equal to 150 + 30, or 180 degrees.

Step-by-step explanation:

We have an expression, and are asked how many terms are in it.

When it comes to terms, these are numbers that have different in symbols, such as variables, exponents, e.t.c.

You have :

1. Constants (4 , 7)

2. Variables ( 4x , 7x)

3. Exponents (4^2 , 7^2)

So we see constants, "23 and 8."

Exponents, "6x."

Therefore, there is two terms in expressions.
