Answer:

2x-9y=-51

2x-3y=-9

subtract question ii from i we get

-6y = -42

y =7

put value of y in 1

2x - 63 = -51

2x= 8

x=4

Answer:

x = 9

Step-by-step explanation:

3x = 27

3/3x = 27/3

x = 9

Answer:

x=55, and y=62.5

Step-by-step explanation:

The reason why x=55 is because x and the angle 125 degrees form a linear pair (180 degrees) Hence,

x+125=180

=> x=180-125

=> x=55

Now coming to y, As we see y and 125 do not form a linear pair, so we know that x=the top angle of the triangle in which angle y is there. And with the information we also find that the triangle in which y is present is an isosceles triangle, so the other 2 angle  than the top angle are equal, which are y and another angle which is also y as they are the same degrees. Hence, we know x=55, then,

55+2y=180(As the angles in a triangle sum up to 180 degrees)  

=> 2y=180-55

=> 2y=125

=> y=125/2

=> y=62.5

Hope my answer helps, Thank you!

easiest thing to do is combine like terms. There are 9 2's, which means 9(2) which equals 18. Now for the X's. There are 9 X's meaning (9)x which is 9x. This all makes up

18+9x

Answer:

10.77

Step-by-step explanation:

√(4-0)²+(10-0)²

√4²+10²

√16+100

√116

10.77

Answer:

11

Step-by-step explanation:

For this problem, we simply need to apply the distance formula:

distance = sqrt[ (y2 - y1)^2 + (x2 - x1) ]

distance = sqrt[ (10 - 0)^2 + (4 - 0)^2 ]

distance = sqrt[ (10)^2 + (4)^2 ]

distance = sqrt[ 100 + 16]

distance = sqrt [ 116 ]

distance ~= 10.77

The approximate distance rounded to a whole number is 11.

Cheers.

Answer:

57.76 in²

Step-by-step explanation:

Plug in 4.6 as x in the equation and solve:

m(x) = x² + 6x + 9

m(4.6) = (4.6)² + 6(4.6) + 9

m(4.6) = 57.76

So, the area of the mat is 57.76 in²

Answer:

C

Step-by-step explanation:

The correct choices would be scatter plots, line graphs, bar graphs option second, third, and fifth are correct.

Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both the co-ordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.

We have:

The chart or graph always use axes both labeled with quantitative values and show individual points of data.

Each point matches with one value on the x-axis and one value on the y-axis.

The chart or graph would be scatter plots, line graphs, bar graphs.

Thus, the correct choices would be scatter plots, line graphs, bar graphs.

Answer:

24 cm²

Step-by-step explanation:

Volume of a prism is equal to the area of the base times the height of the prism.

V = Ah

The volume is 120 cm³, and the height is 5 cm.  Therefore, the area of the base is:

120 cm³ = A (5 cm)

A = 24 cm²

xy = -2

(-3)(2/3) = -2

Answer:

p < 4

Step-by-step explanation:

We are given 0.4p + 1.7 < 3.3.

We solve it like a normal equation by isolating the variable p. Subtract 1.7 from both sides:

0.4p + 1.7 - 1.7 < 3.3 - 1.7

0.4p < 1.6

Divide both sides by 0.4:

p < 1.6/0.4

p < 4

Thus, our possible solutions are p < 4.

Answer:

[1,∞) - All real numbers greater than or equal to 1

Step-by-step explanation:

The answer is [tex]x\geq 1[/tex] or 1, ∞

Step-by-step explanation:

the absolute value is the numbers UNIT DISTANCE from the origin (0,0). since you can't have negative distance, the result is always positive. Can be solved by counting distance on a graph Not by the actual numbers on the line (-1,-2,-3, etc) but by counting the "boxes" from a point to the origin. hope this makes sense!

Answer:

the absolute value of negative number makes it a positive number

There are two conditions :

1) If data consumed is less than or equal to 2 GB.

2) if data consumed is more than 2 GB.

Change in 1st condition is constant i.e $50.

Now, charge in 2nd condition is given by :

[tex]C=15x+50[/tex]

So, money she have to pay in a month where she used ent over by x GB is :

[tex]C(x) = \$50\ , \ 0 \leq x \leq 2\\or\\C(x ) = \$\ (50+15x )\ ,\ x \geq 3[/tex]
