Answer:

Clare didn't change the inequality symbol in the last step to >

Step-by-step explanation:

Given inequality is:

[tex]-4x+3<23[/tex]

Clare's error was in the last step where she multiplied the inequality by -4 to remove the minus sign with x. When an in equality is multiplied/Divided by a negative number then the sign of inequality is reversed. < is changed to > and > is changed to less than.

The answer must have been x > -5

The correct way to solve is:

[tex]-4x+3 <23\\-4x<20\\x>-5[/tex]

Hence,

Clare didn't change the inequality symbol in the last step to >

Answer:

-$13.5

Step-by-step explanation:

Let x be a random variable of a count of player gain.

- We are told that if the die shows 3, the player wins $45.

- there is a charge of $9 to play the game

If he wins, he gains; 45 - 9 = $36

If he looses, he has a net gain which is a loss = -$9

Thus, the x-values are; (36, -9)

Probability of getting a 3 which is a win is P(X) = 1/6 since there are 6 numbers on the dice and probability of getting any other number is P(X) = 5/6

Thus;

E(X) = Σ(x•P(X)) = (1/6)(36) + (5/6)(-9)

E(X) = (1/6)(36 - (5 × 9))

E(X) = (1/6)(36 - 45)

E(X) = -9/6 = -3/2

E(X) = -3/2

This represents -3/2 of $9 = -(3/2) × 9 = - 27/2 = -$13.5

Step-by-step explanation:

Answer:

A: 35

Step-by-step explanation:

DG is the combined segments DO and OG. In other words:

[tex]DG=DO+OG[/tex]

We know that DG is 60. DO is (4x-3) and OG is (2x+21). So, substitute:

[tex]60=(4x-3)+(2x+21)[/tex]

Solve for x. Combine like terms:

[tex]60=6x+18[/tex]

Subtract 18 from both sides:

[tex]42=6x[/tex]

Divide both sides by 6. Hence, the value of x is:

[tex]x=7[/tex]

GO is defined as (2x+21).

So, to find GO, we can now substitute 7 for x and evaluate. Therefore:

[tex]GO=2(7)+21=14+21=35[/tex]

Hence, our answer is A.

Answer:

The answer is

[tex] \huge y - 7 = 2(x - 8)[/tex]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

From the question we have the final answer as

[tex]y - 7 = 6(x - 8)[/tex]

Hope this helps you

Answer:

23

Step-by-step explanation:

First, we can rearrange the equation to make it look simpler.

2+y+11 ---->

y+2+11

Then, we can combine like terms, thus

y+13

Then, we can plug in 10 for y

(10)+13

Combine like terms again, and the answer is:

23

Answer:

Step-by-step explanation:

I'm not entirely sure what the question is, but I suspect the answer is not prime.

9x^2 - 4

factors into two factors  (3x + 2)(3x - 2)

Suppose x = 11 which is prime.

9*121 - 4

1085 which ends in a 5 so the expression is not prime.

In fact, the two factors are 3*11 + 2 = 35  and 3*11 - 2 = 31

31*35 = 1085

9514 1404 393

Answer:

  F.  (3x +2)(3x -2)

Step-by-step explanation:

The given expression is the difference of two squares, so can be factored accordingly.

  9x^2 -4 = (3x)^2 -2^2 = (3x +2)(3x -2) . . . . . matches F

Answer:

Step-by-step explanation:

Let us represent

The number of Box seats = x

The number of grandstand seats = y

The number of bleacher seats cost = z

A minor league baseball park has 6800 seats.

Hence,

x + y + z = 6800

Box seats cost $19, grandstand seats cost $9, and bleacher seats cost $4. When all seats are sold, the revenue is $61200.

Hence:

$19 × x + $9 × y + $4 × z = $61200

19x + 9y + 4 z = 61200

If the number of bleacher seats is 2 times the number of box seats

z = 2x

Hence we substitute

x + y + z = 6800

x + y + 2x = 6800

3x + y = 6800.... Equation 3

y = 6800 - 3x

For Equation 2, substituting 2x for z

19x + 9y + 4z = 61200

19x + 9y + 4(2x) = 61200

19x + 9y + 8x = 61200

27x + 9y = 61200...... Equation 4

Combining Equation 3 and 4

3x + y = 6800.... Equation 3

27x + 9y = 61200...... Equation 4

Note that:

y = 6800 - 3x

We substitute the above in Equation 4

27x + 9(6800 - 3x) = 61200

27x + 61200 - 27x = 61200

Box seats:_______ Grandstand seats:_______ Bleacher seats:______

Answer:

The answer would be x=4.  

Step-by-step explanation: Step 1: Simplify both sides of the equation.

2x+3(5x−7)=47

2x+(3)(5x)+(3)(−7)=47(Distribute)

2x+15x+−21=47

(2x+15x)+(−21)=47(Combine Like Terms)

17x+−21=47

17x−21=47

Step 2: Add 21 to both sides.

17x−21+21=47+21

17x=68

Step 3: Divide both sides by 17.

17x/17=68

17x=68

x=4

Answer:

129 [tex](1.3526)^{t}[/tex]

Step-by-step explanation:

Assuming N = [tex]ab^t[/tex]

t = number of years after 2011

N = number of wolves

When  t = 0 , N = 129

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

a = 129

N = 129[tex]b^{t}[/tex]

When t = 2 , N = 236

therefore 236 = 129 [tex]b^{2}[/tex]

[tex]b^{2}[/tex]  = [tex]\frac{236}{129}[/tex]

therefore; b = 1.3526

Answer expressed in the form of a(b)^t.

129 [tex](1.3526)^{t}[/tex]

Answer:

89

Step-by-step explanation:

We know that all the inside angles of a triangle summed up is 180 so we just do 68 + 23 which is 91 now we use 180 and subtract 91 from it, 180-91 which equals 89

Step-by-step explanation:

3x + 6 = 36 - 3x

6x = 30

x = 5

Answer:

Step-by-step explanation:

Hi there.

1a.  m C= 44 degrees

46+90= 136    180-136=44

1b.  m P= 60 degrees

10+110=120  180-120=60

For future reference, you can solve these with some simple addition. The sum of the angles in any triangle is 180, so add your two given pieces together and subtract it from that to get your missing measure.

2a. Lines a and b have a positive slope. You can tell because they are tilted to the right.

2b. Line d has a negative slope. It's tilted to the left.

(Line c's slope is neither positive or negative because it is zero)

3. x= 65

(I'm not so sure about this one, but I think the angle opposite 25 is also 25, and because of parallel rules the angle above 70 is 110. That means the angle above 110, inside the triangle, is 90. So, we have 90 and 25 and that means 65 is our remaining measure. I really hope this is correct. If you have some sort of notes sheet on the rules of parallel lines and their angle measures, that might be helpful)

Answer:

she charges 20 dollars per photo

for every photo it goes up by 20. you could say that the slope is 20 also.

Answer:

She charges 20 dollars per photo

Step-by-step explanation:

Pick any price on the y axis and divide by the corresponding x-value. For example, the line has a point at (60,3) so we can divide 60 by 3 to give us 20. 20 is therefore the slope of the line.

Answer:

 [tex]y= -\frac{1}{3}x -6[/tex]

Step-by-step explanation:

Using the slope formula, you can form this equation! The slope of any equation would replace the m, and the y intercept would replace b!

I added in the slope formula at the bottom, just in case, so you'll see what I mean!

I hope this helps, and I explained enough! Have a great day c:

In the interval 0 ≤ x ≤ 4 the height of the ball increase and then decrease option (A) is correct.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

It is given that:

The ball was thrown up into the air and allowed to bounce until it came to a halt.

As we know,

The parabola can be defined as the graph of a quadratic function that has something bowl-shaped.

(x - h)² = 4a(y - k)

(h, k) is the vertex of the :

a = √[(c-h)² + (d-k²]

(c, d) is the focus of the parabola:

Thus, in the interval 0 ≤ x ≤ 4 the height of the ball increase and then decrease option (A) is correct.

Answer:

7

Step-by-step explanation:

3×7+1=22

2×7+8=22

Answer:

2

Step-by-step explanation:

In function notation, f(x) equals the y value and the x equals the x value. So this question is asking you to find the value of y when x=-2. To do this find -2 on the graph and find the point with the same x value, then find what value of y it is on. In this case, f(-2)=2.
