Answer:

x=3, y= -6

Step-by-step explanation:

make 4+y= -x as equation (1) and make y=2x-10 as equation (2, then you must find a third equation either from equation (1)or (2). If you choose to find equation (3) from (2) it will be y=2x-10 , then substitute equation (3) from (1) because you can't choose (2) , then it will be 4+(2x-10)= -x

the answer will be x =2

substitute x from equation (3)

y=2x-10

y=2 (2)-10

y= -6

Answer:

x ≤ 10

Step-by-step explanation:

2x-6-5 ≤ 9

2x-11 ≤ 9

2x ≤ 20

x ≤ 10

Given:

An exponential equation passes through the points (0,4) and (2,9).

To find:

Exponential equation that passes through the given points.

Solution:

Let the required exponential function is:

[tex]y=ab^x[/tex]           ...(i)

The function passes through the points (0,4) and (2,9). It means the above equation must be true for these points.

[tex]4=ab^0[/tex]

[tex]4=a(1)[/tex]

[tex]4=a[/tex]

And,

[tex]9=ab^2[/tex]

Substituting [tex]a=4[/tex], we get

[tex]9=(4)b^2[/tex]

[tex]\dfrac{9}{4}=b^2[/tex]

[tex]\pm \sqrt{\dfrac{9}{4}}=b[/tex]

[tex]\pm \dfrac{3}{2}=b[/tex]

In an exponential function b>0. So, [tex]b=\dfrac{3}{2}[/tex].

Putting [tex]a=4,b=\dfrac{3}{2}[/tex] in (i), we get

[tex]y=4\left(\dfrac{3}{2}\right)^x[/tex]

Therefore, the required exponential function is [tex]y=4\left(\dfrac{3}{2}\right)^x[/tex].

Answer:

Lucas monthly net pay is $1758

Step-by-step explanation:

Lucas works for a salary of $2,396 per month.

His deductions include $360 of federal income tax,

$148 for Social Security,

$35 for Medicare, and

a $95 insurance premium.

Now,

2396 - 360 - 148 - 35 - 95 = 1758

Thus, Lucas monthly net pay is $1758

Answer:

23.13m^2

Step-by-step explanation:

We'll use 3.14 for pi as instructed.

We can rearrange the figure to one square and 2 full circles.

Area of the square is 3m*3m = 9m^2

Area of a single full circle is pi*1.5m*1.5m = pi*2.25m^2 = 3.14*2.25m^2 = 7.065m^2

Full area = 9m^2 + 2*7.065m^2 = 9m^2 + 14.13m^2 = 23.13m^2

Answer:

23.14

Step-by-step explanation:

Step-by-step explanation:

Answer:

Cups = 24

Plates = 48

Balloons = 12

Total = 84

Step-by-step explanation:

Serena's mom is planning her birthday party. She bought balloons, plates, and cups. Serena's mom brought twice as many plates as cups. The number of balloons Serena's mom bought was half the number of cups. If Serena's mom bought 84 items, how many of each item did she buy.

Let

c = number of cups

Serena's mom bought twice as many plates as cups.

2c = number of plates

number of balloons Serena's mom bought was half the number of cups

0.5c = the number of balloons

Total items = 84

c + 2c + 0.5c = 84

3.5c = 84

Divide both sides by 3.5

3.5c / 3.5 = 84 / 3.5

c = 24

c = number of cups = 24

2c = number of plates = 2 * 24 = 48

0.5c = the number of balloons = 0.5*24 = 12

Cups = 24

Plates = 48

Balloons = 12

Total = 84

Akiko ate per hour:-

So

20min=1/3h

Total hot dogs

Answer:

2 hot dogs

Step-by-step explanation:

Total hot dogs she ate in 10 hours,

→ 60 hot dogs

Total hot dogs she ate in 1 hour,

→ 60/10

→ 6 hot dogs

The fraction of 20 minutes in a hour,

→ 20 minutes/1 hour

→ 20/60

→ 2/6 = [ 1/3 ]

Rate of hot dogs she ate in 20 minutes,

→ 6 × 1/3

→ 6/3

→ [ 2 hot dogs ]

So, Akiko ate 2 hot dogs in 20 minutes.

Answer

A 7/10

Step-by-step explanation:

if you make it even, you double the 4/5 to make it a 8/10, if you every have a number that is like 4/6-2/18, you triple the 4 to make 12, and triple the 6 to make it 18. so you now have 12/18-2/18=10

So 8/10-1/10=7/10

Answer:

Area of the unshaded sector = 113.4 sq units

Area of the shaded sector = 200.6 sq units

Step-by-step explanation:

First let us calculate the area of the circle

Area of the circle = πr²

radius r  = 10units

Area of the circle = π(10)²

Area of the circle = π(100)

Area of the circle = 3.14(100)

Area of the circle = 314 sq. units

Area of a sector = theta/360 * πr²

Area of the unshaded sector = 130/360 * 314

Area of the unshaded sector = 13/36 * 314

Area of the unshaded sector = 113.389 sq units

Area of the unshaded sector = 113.4 sq units

Area of the shaded sector = Area of circle - Area of the unshaded sector

Area of the shaded sector = 314 - 113.89

Area of the shaded sector = 200.6sq. units

Answer:

Isosceles and Right

Step-by-step explanation:

An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.

Answer:

Isosceles and right

Step-by-step explanation:

We have a picture of triangle and are asked to name it, look at definitions below :

Isosceles - Geometrical figure with three sides and three angles

Right - Triangle where one angle is a right angle (90°)

Scalene - Triangle where all three sides have different lengths

Acute - Triangle where all three sides are less than 90°

If we look at the triangle, we can tell that it has three sides and three angles, therefore isosceles must be in one of the answer choices. Crossing out the options scalene and acute / scalene and right.

Now we have two options and we need to determine whether this triangle is an acute triangle or is a right triangle.

To figure out so we can look at the angle in the bottom left, which when measures equals to 90°. Therefore making it a right triangle and crossing out the other option.

Our answer left is Isosceles and Right.

Answer:

24/60 = 2/5

Step-by-step explanation: dont have one

Answer:

2/5, or 40%

Step-by-step explanation:

The experimental probability is not what the mathematical probability of something always is of happening, but rather the probability based on the pattern of given data in a given experiment. So rather than giving the likelihood of picking a red card on the next pick, you would instead give the "likelihood" of picking a red card based on the trend found in the given data. This would amount to 24/60 which, simplified, would be 2/5, or 40%.
