What will be the new position of the point (−8, 4) when rotated through 90° anti-
clockwise about the origin?

i. (−4, −8) ii. (−4, 8) iii. (4, 8) iv. (2, 4)

Answer:

x= -4

Step-by-step explanation:

so you add 2 to both sides because on one side it's -2, and remember you need to get x by itself, then you solve for x and get the answer which is -4, here are the steps:

x- 2 = -6

x-2+2= -6 + 2

x - 0 = -4

x = -4

Answer:

I cannot give you a full answer because it's missing crucial information- the points on the graph. However, I can give you insight!

Suppose one point is (2,3), if you want to scale it by a factor of 3, you would simply multiply both variables by 3. So the new point would be (6,9).

If you want to scale (4,7) by factor of 2, you would multiply the 4 and the 7 with 2. The new point would be (8,14).

Answer:

c)4x^2-4x+7

Step-by-step explanation:

Sumando los polinomios 4x2-10x-5 y 6x + 12, tendremos:

 4x2-10x-5

        6x + 12

4x ^ 2- 4x + 7

En esta pregunta, los términos semejantes se añaden con los términos semejantes. Cuando se suma -10x a + 6x, se obtiene -4x porque 10x tiene signo negativo y 6x tiene signo positivo. Los diferentes signos se restan y el signo del término más grande se coloca al lado del término resultante.

De manera similar, se resta 5 de 12 y obtenemos 7.

Los términos que están solos siguen siendo los mismos, sus potencias o coeficientes no cambian después de la suma o la resta.

entonces la mejor opción es la opción C

English

Adding the Polynomials 4x2-10x-5 and 6x + 12, we will have:

 4x2-10x-5

        6x+ 12    

4x^2- 4x+7    

In this  question like terms are added with the like terms. When -10x is added to +6x it gives -4x because 10x has negative sign and 6x has positive sign. Different signs are subtracted and the sign of the bigger term is placed beside the resulting term.

Similarly 5 is subtracted from 12 and we get 7.

The terms which are alone remain the same their powers or co efficients do not change after addition or subtraction.

so the best choice is option C

Answer:

3 students with red hair

12 students with brown hair

Step-by-step explanation:

1/6 times 18 = 18/6 = 3 students with red hair

4/6 times 18 = (18 times 4)/6= 12 students with brown hair

Answer:

Red=3

Brown=12

Step-by-step explanation:

So to find 1/6 of 18 you divide 18 by 6 which is 3.

red = 3

Then to find 4/6 well you've already found out 1/6 is 3 so all you need to do is times that by 4.

3x4=12

Brown = 12

Complete Question

Carmen is putting together a business plan for her sandwich restaurant, Subs Away, so she can expand to another location. She wants to include some information about recent sales but only has certain information about last month's sales. She currently offers ham, turkey and vegetarian sandwiches. She sells the ham sandwiches for $10 each and the turkey sandwiches for $11.25.

Last Month's Vegetarian Sales

Total Sandwiches Sold 75

Total Income $712.50

How much does Carmen charge for the vegetarian sandwich?

Answer:

 [tex]X=9.5[/tex]

Step-by-step explanation:

From the question we are told that:

Total Vegetarian Sandwiches Sold [tex]T_{vs}=75[/tex]

Total Vegetarian Sandwiches Income [tex]T_{vi}=$712.50[/tex]

Generally the equation for Cost of vegetarian sandwich is mathematically given by

 [tex]X=\frac{Total\ income\ from\ vegetarian\ sandwich}{No.\ of\ vegetarian\ sandwich\ sold}[/tex]

 [tex]X=\frac{T_{vi}}{T_{vs}}[/tex]

 [tex]X=\frac{712.50}{75}[/tex]

 [tex]X=\$9.5[/tex]

Answer:

w=129.8

Step-by-step explanation:

w + 125.2 = 255​

                  -125.2

w=225-125.2

w=129.8

Answer:

Hope this helps please mark me as branlist.

Step-by-step explanation:

Subtract 125.2 from both sides:

w=125.2=255

w=125.2-125.2=255-125.2

w=255-125.2

w=129.8

Answer:

y = (-1/5)x + 1

Step-by-step explanation:

The slope of this perpendicular line is the negative reciprocal of the slope of the given line y = 5x + 4:  -1/5.

Applying the slope-intercept form of the equation of a line, we get:

2 = (-1/5)(-5) + b, or:

2 = 1 + b

Therefore, b = 1 and the desired equation is:

y = (-1/5)x + 1

Answer:

20m

Step-by-step explanation:

the 4m and 2m on the right can make a rectangle for 8m, then you can make another rectangle on the left side with the remaining 4m (from the 8m side) to make 8m so now were at 16, the triangle remainse, the length is 4m and the height is 2m making 8/2 or 4

16+4 = 20m

[tex]\huge\fbox{5x+20}[/tex]

Step-by-step explanation:

Hi there!

The Distributive Property states that

[tex]\bold{a(b+c)=ab+ac}[/tex]

So, we multiplied a by everything inside the parentheses.

Now, let's use this property to solve our problem:

Answer:

$10 for child tickets and $4 for adult tickets.                                                      

Step-by-step explanation:

Let a = price of adult tickets

     c = price of child tickets

(1)    12a + 6c = 108           (2)    2a + 12c = 128    Multiply (2) by -6

      -12a - 72c = -768

              -66c = -660

                   c = $10                   2a + 12(10) = 128

                                                  2a + 120 = 128

                                                              2a = 8

                                                                a = $4

Something is wrong.  The adult tickets should be more than the child tickets.

But,  according to the info you have given, it comes out to $10 for child tickets and $4 for adult tickets.
