Answer: A triangle can either be... an

Acute-angled triangle.

Obtuse-angled triangle.

Right-angled triangle.

Step-by-step explanation: Here is an image of each type of triangle based on its angles.

Answer:

Perpendicular

Step-by-step explanation:

2x-10y=14

-2x        -2x

-10y=14-2x

/-10      /-10

y=14+1/5

in order for them to be perpendicular the slope has to be the complete opposite to be more exact the number has to be flipped and so does the sign and since -5 was flipped to +1/5 it shows that they would be perpendicular

( sorry if this doesn't make sense, its hard to explain it virtually.)

Answer: [tex]\frac{3}{10}[/tex]

Step-by-step explanation:

Given

Sean paints [tex]\frac{8}{15}[/tex] of a fence in 1 hour

Sean paints [tex]\frac{3}{10}[/tex] part less in the second hour

So, fraction he paints in the second hour = [tex]\frac{8}{15}-\frac{3}{10}=\frac{16-9}{30}=\frac{7}{30}[/tex]

Paint in 2 hours = [tex]\frac{8}{15}+\frac{7}{30}=\frac{16-7}{30}=\frac{9}{30}[/tex]

                          =[tex]\frac{3}{10}[/tex]

No, he did not finish his job

Step-by-step explanation:

Answer:

Cost of Wedding cakes = x = $150

Cost of Birthday cakes = y = $40

Step-by-step explanation:

Let us represent:

Cost of Wedding cakes = x

Cost of Birthday cakes = y

Crazy cakes makes wedding cakes and birthday cakes. One week they made 2 wedding cakes and 5 birthday cakes and made $500.

2x + 5y = 500..... Equation 1

The next week they made 1 wedding cake and 7 birthday cakes but only made $430.

x + 7y = 430..... Equation 2

x = 430 - 7y

We substitute 430 - 7y for x in Equation 1

2x + 5y = 500..... Equation 1

2(430 - 7y ) + 5y = 500

860 - 14y + 5y = 500

860 - 500 = 14y - 5y

360 = 9y

y = 360/9

y = $40

Solving for x

x = 430 - 7y

x = 430 - 7(40)

x = 430 - 280

x = $150

Therefore:

Cost of Wedding cakes = x = $150

Cost of Birthday cakes = y = $40

Answer:

10

Step-by-step explanation:

Answer:

1/10 of the number is 10.

Step-by-step explanation:

We know that 40 is 2/5 of this unknown number, so 4/5 would be 80. Then, to fill up the other 1/5, we must split 40 into half.

1/2 of the number 40 is equal to the number 20.

80 + 20 = 100, so 5/5 would be equal to 100.

Now, we have to find one tenth of the number 100.

1/10 of the number 100 is the number 10. (1/10 of 100 = 10)

The answer to the question is 10.

7.25h + 9(20) = 288.75

Multiply 9 by 20:

7.25h + 180 = 288.75

Subtract 180 from both sides:

7.25h = 108.75

Divide both sides by 7.25

h = 108.75 / 7.25

h = 15

He spent 15 hours delivering pizzas.

Answer:

12

Step-by-step explanation:

9x20=180 288.75-180=108.75 108.75÷9=12.0833333333

Answer:

24.187

Step-by-step explanation:

Answer:

No Solution.

Step-by-step explanation:

For starters, here are our two equations:

[tex](x^2-x-6)>0[/tex]

[tex]10-2x<5[/tex]

The first option is to solve for x in our second equation. First, we add 2x to both sides to get [tex]10<5+2x[/tex]. Then, we subtract 5 from both sides to get [tex]2x<5[/tex]. Finally, we divide both sides by 2 to get [tex]x<2.5[/tex]. We can plug in 2.5 into our second equation to test if it works. If it does not work, then anything less than 2.5 won't work, and the solution would be impossible.

Now we can plug in our values into our first equation. We now have the equation [tex]2.5^2-2.5-6>0[/tex]. We can simplify to get [tex]-2.25>0[/tex]. This test failed, so there are no solutions. A solution would be impossible.

Answer:

(0, 3) and (-3, 0) are just two out of an infinite number of other points

Step-by-step explanation:

I found these 2 points by plugging in 0 for x and y would equal 3

Then I plugged in 0 for y and x would equal -3

Answer:

2

Step-by-step explanation:

Ok, so they gave you these two points, since I can't actually graph it, then we can just make a table...

x      y

4     6

6     10

From 6 to 10, you add 4 (this is for the y section)

From 4 to 6 you add 2 (this is for the x section)

Now you need to divide the y by the x....

y/x = 4/2 = 2

And 2 will be the answer for your slope, given these 2 points.

Hope this helped!

Answer:

Step-by-step explanation:

Use Pythagorean theorem.

Hypotenuse² = base² + altitude²

5)  x²  = 12² + 6²

         = 144 + 36

  x²  = 180

x = √180

x = 13.42 ft

6) 25² = x² + 19²

625 = x² + 361

625 - 361 = x²

x² = 264

x = √264

x = 16.25 m

7)  x² = 7² + 576

        = 49 + 576

        = 625

x = √625

x = 25 in

8)  2.5² = 2²+ x²

6.25 = 4 + x²

6.25 - 4 = x²

x² = 2.25

x = √2.25

x = 1.5 yd

Answer:

Step-by-step explanation:

Answer:

-9/3 or -3

Step-by-step explanation:

[tex]Slope= \frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]

Lets start with the y's, substitute:

-6-3=-9

Then the x's, substitute:

5-2=3

Substitute back into the fraction:

-9/3 or

-3

Answer:

m = -3

Step-by-step explanation:

y2-y1

--------

x2-x1

-6-3/5-2

-9/3

-3

Therefore, your answer for slope would be m = -3

Answer:

y = -8/5x + 23/5

Step-by-step explanation:

Complete question

Write the equation of the line, in slope-intercept form, that has a slope of -8/5and contains the point (6, –5)

The equation of a line in pint slope form is expressed as;

y - y0 = m(x-x0)

Given

m = -8/5

(x0, y0) = (6, -5)

Substitute into the formula

y - (-5) = -8/5(x-6)

y+5 = -8/5(x-6)

Multiply through by 5

5(y+5) = -8(x-6)

5y + 25 = -8x + 48

5y = -8x +48 - 25

5y = -8x + 23

y = -8/5x + 23/5

Hence the equation in slope intercept form is y = -8/5x + 23/5

Answer:

The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value "5" is the Y Coordinate. Also called "Ordinate"

Step-by-step explanation:

Answer:

In math a letter is always a variable. If you are solving an equation and the letter y is there you have to solve for y. So in math y stands for a variable.

Answer:

F(x)=2/3x-8

Step-by-step explanation:

To find the answer to this problem, you can tell first that the entire rhombus is 360 degrees. And PLA is the same as ANP so ANP is 122 degrees.

360 - 122 + 122 = 116

116 divided by 2 = 58

measure LPN is 58 degrees

and half of 58 is 29

so measure LPA is 29 degrees
