Answer:

Explanation at the bottom

Step-by-step explanation:

To find the slope with the 2 points use this ---> [tex]\frac{y2 - y1}{x2 - x1}[/tex] Ex: Points (9, 3) (6, 12) --> write it this way [tex]\frac{12 - 3}{6 - 9}[/tex] = [tex]\frac{9}{-3}[/tex] = -3 so -3 would be the slope of that line.

Then to find the y- intercept use the slope and the numbers from one of the points like this ---->   y = mx + b we are looking for b.  

(plugging in the first point)  (using the point (9,3))

3 = -3(9) + b

3 = -27 + b (add 27 on both sides)

30 = b (that's your y- intercept)

(Full equation is)  

y = -3x + 30

Step-by-step explanation:

Distribute

3x-x+4=18

Combine like terms

2x+4=18

Subtract 4 on both sides

2x=14

Divide 2 on both sides

X=7

Answer:

x = 7

Step-by-step explanation:

3x - (x - 4) = 18 =

3x - x + 4 = 18 =

2x + 4 = 18 =

2x + 4 - 4 = 18 - 4

2x = 14

Answer:y=4x^2+5x+1

Step-by-step explanation:

Just did the quiz on big ideas math

The equation of the parabola which passes through the points  (-2, 7) , (1, 10) , and (2, 27) is  y = (25/6)x² -(17/6)b + (1/3)c.

A plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line.

We know equation of a parabola is y = ax² + bx + c.

Given are three points  (-2, 7) , (1, 10) , and (2, 27).

If these points lie on the parabola it must verify that [tex]y_o = ax^2_o + bx_o + c.[/tex]

Therefore,

7 = a(-2)² + b(-2) + c = 0

7 = 4a - 2b + c ...(i)

10 = a(1)² + b(1) + c = 0

10 = a + b + c ...(ii)

27 = a(2)² + b(2) + c

27 = 4a + 2b + c...(iii)

Now adding eqn(i) and eqn(ii) we get 8a + 2c = 34...(iv)

Now multiplying eq(ii) by 2 and adding it to eq(i) we get 6a + 3c = 27...(v).

Now multiplying eqn(iv) by 3 and (v) by 2 and subtracting them we get a = 25/6.

Putting the value of an in eqn(iv) we get c = 1/3.

Similarly substituting the value of a and c in eqn(ii) we get b = -17/6.

∴ The equation of the parabola is y = (25/6)x² -(17/6)b + (1/3)c.

Answer:

See below

Step-by-step explanation:

Given triangle JKL

a) Perpendicular segments are

b) Equal angles are

Answer:

60 problems correct so b is correct

Answer:

The answer is that angle T is 41 degrees.

Step-by-step explanation:

Line USP is a 180 angle. Knowing this, you can subtract 104 from 180.

You get 76. Then, you add 76 to 63.

The sum is 139. Then, to find the answer, you subtract 139 from 180. You know to use 180 because EVERY TRIANGLE'S ANGLES always add up to 180.

180 minus 139 is 41. This is your answer: Angle T is 41 degrees in measure.

Answer:

Option (3)

Step-by-step explanation:

To solve this question we will use the formula,

Distance (d) between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between Mathtown (-2, 5) to Geometryville (3, -1)

[tex]d_1=\sqrt{(3+2)^2+(-1-5)^2}[/tex]

    [tex]=\sqrt{25+36}[/tex]

    [tex]=\sqrt{61}[/tex]

    [tex]=7.81[/tex]

Distance between Geometryville (3, -1) and Algebra Springs (-6, -5)

[tex]d_2=\sqrt{(3+6)^2+(-1+5)^2}[/tex]

    [tex]=\sqrt{81+16}[/tex]

    [tex]=\sqrt{97}[/tex]

    [tex]=9.85[/tex]

Distance between Algebra Springs (-6, -5) and Mathtown (-2, 5)

[tex]d_3=\sqrt{(6-2)^2+(5+5)^2}[/tex]

    [tex]=\sqrt{16+100}[/tex]

    [tex]=\sqrt{116}[/tex]

    [tex]=10.77[/tex]

Now total distance traveled by Kim = [tex]d_1+d_2+d_3[/tex]

                                                           = 7.81 + 9.85 + 10.77

                                                           = 28.43

Therefore, Option (3) will be the answer.

Answer:

[tex]\boxed {m = -6}[/tex]

Step-by-step explanation:

Use the Slope Formula to help you determine the slope of the following two points:

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

(Where [tex](x_{1}, y_{1})[/tex] is the first point and [tex](x_{2}, y_{2})[/tex] is the second point)

-Apply both points onto that formula:

[tex](x_{1}, y_{1}) = (1, 1)[/tex]

[tex](x_{2}, y_{2}) = (0, 7)[/tex]

[tex]m = \frac{7 - 1}{0 - 1}[/tex]

-Solve:

[tex]m = \frac{7 - 1}{0 - 1}[/tex]

[tex]m = \frac{6}{-1}[/tex]

[tex]\boxed {m = -6}[/tex]

Answer:

6 candy boxes

Step-by-step explanation:

Since they both bought their own popcorn that means they both spent $8 on popcorn making that a total of $16. Therefore we now only need to find one variable which is the number of candy boxes that they bought in order to reach the $25 total that they spent. This variable can be represented as x in the following algebraic equation.

(2*8) + 1.50x = 25

16 + 1.50x = 25 ... subtract 16 from both sides

1.50x = 9 ... divide both sides by 1.50

x = 6

Finally, we can see that Billy and Tommy bought a total of 6 candy boxes.

Answer:

             The smaller number:  a = 10

             The larger number is 32

Step-by-step explanation:

a - the smaller number

2a - twice the smaller number

2a+12   - twelve more than the twice smaller number (the larger number)

a + 2a+12  - the sum of the numbers

a + 2a+12 = 42

     -12              -12

          3a  =  30

The solution to the inequality 5.6 + 2.2x > 65.6 - 1.8x is x > 15.

Given the inequality in the question:

5.6 + 2.2x > 65.6 - 1.8x

To solve the inequality 5.6 + 2.2x > 65.6 - 1.8, first, collect and combine the like terms on both sides of the inequality:

5.6 + 2.2x > 65.6 - 1.8x

Add 1.8x to both sides:

5.6 + 2.2x + 1.8x > 65.6 - 1.8x + 1.8x

5.6 + 2.2x + 1.8x > 65.6

5.6 + 4x > 65.6

Subtract 5.6 from both sides of the inequality:

5.6 - 5.6 + 4x > 65.6 - 5.6

4x > 60

Divide both sides by 4 to isolate the variable x:

x > 60/4

x > 15

Therefore, x is greater than 15.

Answer:

Step-by-step explanation:

Guessing!!! hope it's correct,

Because

Percent Decrease = Percentage Decrease=Starting Value−Final Value|Starting Value|×100

If Haley got a 93% on her first math test and an 86% on her second test. Her percent decrease from Test 1 to Test 2 to the nearest tenth will be 7.5%

Using this formula

Percentage Decrease=Starting percentage−Final percentage÷ Starting percentage×100

Where:

Starting percentage=93%

Final percentage=86%

Let plug in the formula

Percentage Decrease=93%-86%÷93%×100

Percentage Decrease=7%÷86%×100

Percentage Decrease=7.5%
