Answer:

x = 19

Step-by-step explanation:

(5x + 2)° + 83° = 180°

✍️Reason: both are linear pair angles. Linear pair angles are supplementary.

Solve for x

5x + 2 + 83 = 180

5x + 85 = 180

Subtract 85 from both sides

5x = 180 - 85

5x = 95

Divide both sides by 5

x = 95/5

x = 19

Step-by-step explanation:

Answer: y = -1*x^2 - 4

Step-by-step explanation:

A generic quadratic equation is written as:

y = a*x^2 + b*x + c

we need to find the values of a, b, and c

We have the table:

x     y = f(x)

-4     -20

-3       -13

-2        -8

-1         -5

0         -4

1          -5

In the table we can see two things:

y(0) = a*0^2 + b*0 + c = c = -4

Then we know that:

y(x) = a*x^2 + b*x - 4

Now we only need to find a and b.

We also can see that we have symmetry around the point x = 0, this means that x = 0 is the vertex of the quadratic equation, and for a general case the vertex is at:

x = -b/2a

and this is equal to zero:

-b/2a = 0

then we must have b = 0.

So for now, the equation is:

y = a*x^2 -4

Now we can just replace the values of any of the points to find the value of a, for example we can use the point (1, -5)

this means that:

y = -5 = a*1^2 - 4

    -5 = a - 4

    -5 + 4 = a

        -1 = a

Then the quadratic equation is:

y = -1*x^2 - 4

Answer:

Hai is incorrect, there is no solution to this equation.

Step-by-step explanation:

1.) Expand.

3x-4=2x+6+x3x−4=2x+6+x

2.) Simplify  2x+6+x2x+6+x  to  3x+63x+6.

3x-4=3x+63x−4=3x+6

3.) Cancel 3x3x on both sides.

-4=6−4=6

4.) Since -4=6−4=6 is false, there is no solution.

Therefore, this equation has no solution

Answer:

[tex]\approx \frac{11}{40}[/tex]

Step-by-step explanation:

Juice squeezed from first orange = [tex]\frac{4}{17}[/tex] = 0.235

Juice squeezed from second orange = [tex]\frac{3}{10}[/tex] = 0.3

Juice squeezed from third orange = [tex]\frac{9}{20}[/tex] = 0.45

Juice squeezed from fourth orange = [tex]\frac{3}{11}[/tex] = 0.27

Juice squeezed from fifth orange = [tex]\frac{7}{15}[/tex] = 0.47

Total juice squeezed from all the five oranges = 0.235 + 0.3 + 0.45 + 0.27 + 0.47 = 1.725

Total juice to be squeezed = 2 cups

More juice required = 2 - 1.725 = 0.275 [tex]\approx \frac{11}{40}[/tex]

Therefore, to make it 2 cups of orange juice for the family, about [tex]\approx \frac{11}{40}[/tex] cups of more juice is required.

C) [tex]x+y=20[/tex], [tex]3x+2y = 50[/tex]

D) [tex]x=10, y=10[/tex]

E) Yes, the result satisfies the equations.

Step-by-step explanation:

Let number of kilos of mango bought = [tex]x[/tex]

Let number of kilos of atis bought = [tex]y[/tex]

Total number of kilos bought = 20

A) [tex]x+y=20[/tex]

Cost of mango per kg = 60

Cost of mango for [tex]x[/tex] kg = [tex]60x[/tex]

Cost of atis per kg = 40

Cost of mango for [tex]y[/tex] kg = [tex]40y[/tex]

Total cost is: Cost of mango + Cost of atis = 1000

B) Cost function is:

[tex]60x+40y=1000\\\Rightarrow 3x+2y = 50 ...... (2)[/tex]

C) System of equations are:

[tex]x+y=20[/tex] ...... (1)

[tex]3x+2y = 50[/tex]...... (2)

D) Using elimination method:

Multiplying equation (1) with 2 and subtracting from (2):

[tex]x = 10[/tex]

By equation (1):

[tex]\Rightarrow y =10[/tex]

E) Putting both the values in LHS of equation (1):

10+10  = 20 = RHS

Putting both the values in LHS of equation (2):

[tex]3\times 10 +2\times 10[/tex] = 50 = RHS

Yes, the result satisfies the equations.

Answer:

29.7

Step-by-step explanation:

y = 2.7x + 2.7

y = 2.7(1) + 2.7 = 5.4

y = 2.7(2) + 2.7 = 5.4 + 2.7 = 8.1

y = 2.7(3) + 2.7 = 8.1 + 2.7 = 10.8

y = 2.7(4) + 2.7 = 10.8 + 2.7 = 13.5

y = 2.7(10) + 2.7 = 27 + 2.7 = 29.7

Answer:

trumpeter swans = t = 41

sand-hill cranes = s = 26

chickadees = c = 164

dusky grouses = d = 82

Step-by-step explanation:

Total birds = 313

Let

trumpeter swans = t

sand-hill cranes = s

chickadees = c

dusky grouses = d

t = 15 + s

c = 2d

d = 2t

t + s + c + d = 313

(15+s) + s + 2d + d = 313

15 + s + s + 2(2t) + 2t = 313

15 + 2s + 4t + 2(15+s) = 313

15 + 2s + 4(15 + s) + 30 + 2s = 313

15 + 2s + 60 + 4s + 30 + 2s = 313

105 + 8s = 313

8s = 313 - 105

8s = 208

s = 208 / 8

= 26

s = 26

t = 15 + s

= 15 + 26

= 41

d = 2t

d = 2(41)

= 82

c = 2d

c = 2(82)

= 164

trumpeter swans = t = 41

sand-hill cranes = s = 26

chickadees = c = 164

dusky grouses = d = 82

Answer:

[tex]Feeds = 11.76kg[/tex]

Step-by-step explanation:

Given

[tex]Field\ A= 56\%[/tex]

[tex]Field\ B= The\ rest[/tex]

[tex]Bag = 21kg\ feed[/tex]

Required

Determine how much goats in field A, get.

To do this, we simply multiply the percentage feed received by goats in field A by the actual bags of feeds

i.e.

[tex]Feeds = 56\% * 21kg[/tex]

Convert percentage to decimal

[tex]Feeds = 0.56 * 21kg[/tex]

[tex]Feeds = 11.76kg[/tex]

Hence, goats in field A get 11.76kg of feeds

The answer is -3

i just took the quiz and got it right

The rate of change for the given data is -3. Therefore, option A is the correct answer.

The coordinates from the given data are (-1, 5) and (2, -4).

The rate of change, or the slope, is calculated as Δy/Δx , or (y2−y1)/(x2−x1). The slope-intercept equation of a line is y=mx+b , where m is the slope and b is the initial value.

Here, (x1, y1)=(-1, 5) and (x2, y2)=(2,-4)

Rate of change = (-4-5)/(2+1)

= -9/3

= -3

The rate of change for the given data is -3. Therefore, option A is the correct answer.

Answer:

5 Laps

Step-by-step explanation:

The question says that she runs the same distance everyday. This shows us that...

2 laps on a running trail and 6 more miles = 4 laps on a running trail and 2 more miles

We can turn laps into the variable L and miles into the variable M to create an equation

2 L + 6 M = 4 L + 2 M

We can start by subtracting 2 M from both sides to get:

2 L + 4 M = 4 L

Now, we can subtract 2 L from both sides

4 M = 2 L

This tells us that 2 laps are 4 miles which means that 1 lap is 2 miles.

Now, we can break down either side of the equation. Let's break down

2 L + 6 M

First, we can turn the miles into laps. We know that 2 miles is one lap so we can divide 6 by 2. Our Equation:

2 L + 3 L

Now, we can simplify this :

5 L

Now we know that she ran 5 laps on saturday.

math

Answer:

Step-by-step explanation:

The number of years between 1996 to 2002 will be:

= 2002 - 1996

= 6 years

The relationship relating the value of the card y in dollars and the number of years x the player has been in retirement can be expressed as an equation in the form of:

y = 5.71 + 1.98x

where x = 6 years

y = 5.71 + 1.98(6)

y = 5.71 + 11.88

y = $17.59

The value of the card in 2002 ​is $17.59.

The relationship between x and y isn't proportional in this case.

Answer:

C. -3

Step-by-step explanation:

You can do this using two different methods.

First, slope is written rise over run, or y over x. We can find two points and count how much we need to rise and run. The graph already includes the points (2,-3) and (-1, 6), which we will use. If you carefully look at the graph, you can see that if you start from the point (2,-3), you can rise 9 and run -3 to get to the point (-1, 6), which brings me to the next step. As I stated in the beginning, slope is written rise over run. Therefore, the slope is 9/-3, which simplifies to -3, answer choice C.

Another way you can do this is subtracting the y's and subtracting the x's in the same order. The y's go over the x's, and is basically written as a fraction. For this method, we still need two points. We will use the same points as above and listed on the graph, points (2,-3) and (-1, 6). The y's are -3 and 6, and the x's are 2 and -1. Now, subtract.

-3-6  =-9=-3

2-(-1)= 3

As you can tell, both methods of solving for slope worked, and the answer is choice C.

I hope this helps you!! Have a great day ^^
