Solve for x. Round to the nearest tenth, if necessary. 1.8 & x

Answer:

y = 2x + 4

Step-by-step explanation:

(x₁ , y₁) --> (0 ,4)    & (x₂ , y₂) = (6 , 16)

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

          [tex]= \frac{16-4}{6-0}\\\\=\frac{12}{6}\\\\m = 2[/tex]

(x₁  , y₁) --> (0 ,4)

y - y₁ = m(x - x₁)

y - 4 = 2(x - 0)

y - 4 = 2x

   y = 2x + 4

Answer:

2/3

Step-by-step explanation:

If we know two points we can find the slope using

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

    = ( 3 -1)/(8 - 5)

    = 2/3

Dado :

Para pedidos de hasta una docena; par de pantimedias Glamour Costo S / 5

Para pedidos de más de una docena; par de pantimedias Glamour Costo S / 3

Función de costo:

Para x ≤ 12

Costo, C = 5x

Para x> 12

Costo, C = 3x

Costo de 5 pedidos:

x = 5

Costo, C = 5 (5) = S / 25

Costo de 15 pedidos:

x = 15

Costo, C = 3 (15) = S / 45

Costo de 25 pedidos:

x = 25

Costo, C = 3 (25) = S / 75

Answer:

  3) x = 55, y = 123, z = 123

  4) x = 276°

Step-by-step explanation:

Angles P and Q are alternate interior angles, so are congruent.

  P = Q

  3x -42° = 2x +13°

  x = 55° . . . . . . . . . . . add 42°-2x

Then Q = 2x +13 = 2(55°) +13° = 123°.

Angles Y, P, Q, and Z are all congruent, so all have the same measure.

  Y = Z = 123°

__

If you draw a horizontal line parallel to AB and CD through point O, then small angle POQ is divided into parts that are congruent with angles APO and CQO. That is, small angle POQ = 48° +36° = 84°.

Large angle POQ is then 360° -84° = 276°

Salary: $95000

Step-by-step explanation:

Write an equation to model the salary and its raise per year. Add the base salary to the raise per year salary times (x). Where the parameter (x) represents the number of years spent in the company.

Company (1):

75000 + 2500x

Company (2):

55000 + 5000(x)

One is asked at which year will the salaries be the same. Equate the two expressions and solve for the variable (x):

75000 + 2500x = 55000 + 5000(x)

Inverse operations:

75000 + 2500x = 55000 + 5000x

20000 + 2500x = 5000x

20000 = 2500x

8 = x

Substitute (x) into any one of the experssions and simplify to solve the epxression,

55000 + 5000(x)

x = 8

= 55000 + 5000(8)

= 55000 + 40000

= 95000

Given:

The vertex of a triangle MNP are M(-4, 6), N(2, 6), and P(-1, 1).

The rule of dilation is:

[tex](x,y)\to (1.5x,1.5y)[/tex]

The image of triangle MNP after dilation is M'N'P'.

To find:

The coordinates of the endpoints of segment M'N'.

Solution:

The end points of MN are M(-4, 6) and N(2, 6).

The rule of dilation is:

[tex](x,y)\to (1.5x,1.5y)[/tex]

Using this rule, we get

[tex]M(-4,6)\to M'(1.5(-4),1.5(6))[/tex]

[tex]M(-4,6)\to M'(-6,9)[/tex]

And,

[tex]N(2,6)\to N'(1.5(2),1.5(6))[/tex]

[tex]N(2,6)\to N'(3,9)[/tex]

The endpoints of M'N' are M'(-6, 9) and N'(3, 9).

Therefore, the correct option is B.

196596               196600                      197000                        200000

193171                 193200                       193000                       190000

The ratio 4:3 means for every 4 girls there are 3 boys.

Divide total girls by 4, multiply that by 3 to get total boys:

180/4 = 45 x 3 = 135

There are 135 boys

For total students add boys and girls:

180 + 135 = 315 total students

Step-by-step explanation:

To make 1 sundae, the total number of spoons use of sprinkles=4. Let the number of sundaes made in 32 spoonfuls of sprinkles be x. Also the number of sprinkles and the number of sundaes are directly proportional. Therefore, Hence, if 32 spoonfuls of sprinkles is used, then the ice-cream shop can make 8 sundaes.

±5√2/4

Answer:

Step-by-step explanation:

The position function for this is given as

[tex]h(t)=-16t^2+48t+2.75[/tex] where h(t) is the height of the football at any time t. If the ball is caught at 5.25 feet, that h(t) value is 5.25 since we are looking for the time the ball was in the air from its initial 2.75 feet to 5.25 feet, when it was caught.

[tex]5.25=-16t^2+48t+2.75[/tex] and set this equal to 0:

[tex]-16t^2+48t-2.5=0[/tex] and factor.

When we factor we get

t = .05 and t = 2.95 in seconds.

That first time tell us how long it takes to go from the initial height of 2.75 to a point 2.5 feet higher, 5.25. To get get back down to the 5.25 foot height on the other side of the vertex, is 2.95 seconds. So the total time the ball was in the air was 3 seconds exactly.

Answer:

Without thinking too hard, by adding the progression of number until we reach  >200 and counting what n value we have we can solve this question.

The rule of this progression is to + 4 every time.

2 + 6 + 10 + 14 + 18 + 22 + 26 + 30 + 34 + 38 + 42

This will give us 242, which is greater than 200. There are 11 numbers here, so the n value is 11.

Answer:

Hello,

Step-by-step explanation:

Using n terms, the arithmetic sequence will be:

2,6,10,14,...,?

=0*4+2,1*4+2,2*4+2,3*4+2,...,(n-1)*4+2

s=(0*4+2)+(1*4+2)+(2*4+2)+(3*4+2)+...+(n-1)*4+2 >200

(2+2+2+...+2)+4(0+1+2+...+(n-1)) > 200

2*n+4*(0+(n-1))*n/2 >200

2n+2(n²-n) > 200

2n² >200

n² > 100

n >10

the smallest value of n is 11.

11 th term is (11-1)*4+2=42

sequence={2,6,10,14,...,42} which sum is 2*11²=242

Answer:

x = 5

Step-by-step explanation:

4x + 17 = 12x - 23

23 + 17 = 12x - 4x

      40 = 8x

       8      8

       5  =  x

The value of x should be 5.

A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal).

As, to from the square using the dimension of parallelogram the value of x should be 5

as the side of square is equal.

4x + 17 = 12x - 23

23 + 17 = 12x - 4x

40 = 8x

5  =  x
