Hayleigh took a long multiple-choice, end-of-year math test. The ratio of the number of problems Hayleigh got incorrect to the number of problems she got correct is 2:9. If Hayleigh missed 8 questions, how many did she get correct?

Final Answer:

8/49!

Step-by-step explanation:

4/7 ÷ 7/2

4/7 ÷ 2/7

4/7 × 2/7 = 8/49

Answer:

B. (x,y) --> (4x - 10, 4y - 8)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, dilation and rotation.

If a point X(x, y) is translated a units right and b units up, the new location is (x + a, y + b) also If a point X(x, y) is translated a units left and b units down, the new location is (x - a, y - b)

If a point X(x, y) is dilated by the factor k the new location is X'(kx, ky).

Triangle ABC has vertices at A(10,5), B(10,15), and C(5,5), If it is dilated by a factor of 4, the new location is A*(40, 20), B*(40, 60) and C*(20, 20). If then a translation of 10 units left and 8 units down, the new points are A'(30, 12), B'(30, 52), C'(10, 12).

This is a transformation of (x,y) --> (4x - 10, 4y - 8)

Answer:

let the $12 dish be x and the other y

x + y = 12 <--- 1

12x + 10.50y= 138 <--- 2

multiply equation 1 by 12

so now we have

12x + 12y = 144

12x + 10.50y = 138

now subtract each one and that cancels out x

1.5y = 6

y = 4

now subsitute that into any equation

x + 4 = 12

x = 12 - 4

x = 8

Answer:

80 kilometers

Answer:

p = 78/5

Step-by-step explanation:

Solve for p:

5 (p - 3) = 63

Divide both sides of 5 (p - 3) = 63 by 5:

(5 (p - 3))/5 = 63/5

5/5 = 1:

p - 3 = 63/5

Add 3 to both sides:

p + (3 - 3) = 63/5 + 3

3 - 3 = 0:

p = 63/5 + 3

Put 63/5 + 3 over the common denominator 5. 63/5 + 3 = 63/5 + (5×3)/5:

p = 63/5 + (5×3)/5

5×3 = 15:

p = 63/5 + 15/5

63/5 + 15/5 = (63 + 15)/5:

p = (63 + 15)/5

63 + 15 = 78:

Answer: p = 78/5

Answer:

x=7

Step-by-step explanation:

2x+7=21

Minus 7

2x=14

Divide 2

x=7

Answer:

2x = 54

Step-by-step explanation:

The given information;

x = 3^3

solve

x = 27

(beacuse 3^3 = 3 * 3 * 3 = 27

find 2x:

2x = 2 * x

x= 27

2 * 27 = 54

2x = 54

Step-by-step explanation:

I plugged all of these into a graph and the used the graph trace feature (after setting the step to 1) and traced all of the graphs to find if they hit the point (8,2). B-d do so we can eliminate a and then you can either graph the line y=-2x+4 or just go with b because they have the same slope (-2x). Hope that helps!

Step-by-step explanation:

Answer:

a + b = 5 ...........1

6a + 4b = 24.50 ......... 2

Step-by-step explanation:

Let a be the amount of pounds of apricot bought

Let b be the amount of pounds of banana bought

If he buys a total pounds of 5 pounds then;

a + b = 5 ...........1

Also if a pound's of apricots for $6 per pound, total amount of aprciots bought will be $6a

Also if b pound's of banana is for $4 per pound, total amount of banana bought will be $4b

If he spends a total of $24.50 on both banana and apricots, then:

6a + 4b = 24.50 ......... 2

The system of equations that represents the constraints in the situation is:

a + b = 5 ...........1

6a + 4b = 24.50 ......... 2

Answers:

x = 4

RM = 7

======================================================

Explanation:

The midpoint cuts the larger segment RS in two equal halves, so RM = MS

RM = MS

x+3 = 2x-1

3+1 = 2x-x

4 = x

x = 4

RM = x+3

RM = 4+3

RM = 7

MS = 2x-1

MS = 2*4-1

MS = 7

Both RM and MS are 7 units long, which confirms our answers.

RS = RM+MS

RS = 7+7

RS = 14

Answer:

S(p(x)) = 140,000(0.9732)^x

Step-by-step explanation:

Given the population functions:

ENVIRONMENTALIST: decline by 3.5% annually

p(x) = 140,000(0.965)^x

CONSERVATIONISTS: Increase by 0.85% annually ;

S(p) = p(1.0085)^x

Formulate S(p(x)) rounded to the nearest ten thousand

p(x) = 140,000(0.965)^x

S(p) = p(1.0085)^x

S(p(x)) = p(1.0085)^x

Where p(x) = 140,000(0.965)^x

S(p(x)) = 140,000(0.965)^x(1.0085)^x

S(p(x)) = 140,000(0.9732025)^x

S(p(x)) = 140,000(0.9732)^x

Answer:

Step-by-step explanation:

Edge

Answer:

-4 Degrees Fahrenheit

Step-by-step explanation:

Given

[tex]Initial\ Temperature = 8[/tex] ---- at 10am

[tex]Difference = -3[/tex]

Required

Determine the final temperature at 2pm

First, we need to determine the hour from 10am to 2pm (Both inclusive)

[tex]Interval = 2pm - 10am + 1hr[/tex]

[tex]Interval = 4hr + 1hr[/tex]

[tex]Interval = 5hr[/tex]

To solve further, we make use of the following Arithmetic Progression formula:

[tex]T_n = a + (n - 1)d[/tex]

Where

[tex]a = 8[/tex] --- Initial

[tex]d = -3[/tex] --- difference

[tex]n = 5[/tex] -- 5th term

[tex]T_n[/tex] --- Final temperature at 2pm

So: we have:

[tex]T_n = 8 + (5 - 1) * -3[/tex]

[tex]T_n = 8 + (4) * -3[/tex]

[tex]T_n = 8 + 4 * -3[/tex]

[tex]T_n = 8 -12[/tex]

[tex]T_n = -4[/tex]

Hence:

The temperature is -4 Degrees Fahrenheit

Answer:  i have a answer but it is not up there srry

Step-by-step explanation:  

Answer:

Step-by-step explanation:

Given the equation 250 + 200h = 300 + 180h, we are to find the amount of credit hours will a student have to take for the two tuition costs to be equal, to do that we need to make h the subject of the formula:

250 + 200h = 300 + 180h

collect like terms

200h - 180h = 300-250

20h = 50

2h = 5

Divide both sides by 2:

2h/2 = 5/2

h = 5/2

h = 2.5hr

Hence the student will take 2.5hr.

Answer:

h = 2.5 credit hours

Answer:

All results in the explanation

Step-by-step explanation:

To make the equation of the line, we only need two points. Select from the table the points (-1,4) and (3,9).

First, find the slope of the line:

We know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]

Substituting:

[tex]\displaystyle m=\frac{9-4}{3+1}=\frac{5}{4}[/tex]

This value is used in the slope-point form of the line:

[tex]\displaystyle y-k=\frac{5}{4}(x-h)[/tex]

Where (h,k) is a point from the table, select for example (3,9):

[tex]\displaystyle y-9=\frac{5}{4}(x-3)[/tex]

Operate:

[tex]\displaystyle y=\frac{5}{4}\cdot x-\frac{5}{4}\cdot 3+9[/tex]

[tex]\displaystyle y=\frac{5}{4}\cdot x+\frac{-15+36}{4}[/tex]

The equation of the line is:

[tex]\boxed{\displaystyle y=\frac{5}{4}\cdot x+\frac{21}{4}}[/tex]

Now complete the table.

For x=0:

[tex]\displaystyle y=\frac{5}{4}\cdot 0+\frac{21}{4}[/tex]

[tex]y=\frac{21}{4}[/tex]

For x=15

[tex]\displaystyle y=\frac{5}{4}\cdot 15+\frac{21}{4}[/tex]

[tex]\displaystyle y=\frac{75}{4}+\frac{21}{4}=\frac{96}{4}=24[/tex]

y=24

For y=1.5, find x:

[tex]\displaystyle 1.5=\frac{5}{4}\cdot x+\frac{21}{4}[/tex]

Operate:

[tex]\displaystyle 1.5-\frac{21}{4}=\frac{5}{4}\cdot x[/tex]

Multiply by 4:

[tex]\displaystyle 6-21=5 x[/tex]

Solve:

[tex]x=-15/5=-3[/tex]

x=-3

Answer:

All results in the explanation

Step-by-step explanation:

To make the equation of the line, we only need two points. Select from the table the points (-1,4) and (3,9).

First, find the slope of the line:

We know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

\begin{gathered}\displaystyle m=\frac{y_2-y_1}{x_2-x_1}\\\end{gathered}m=x2−x1y2−y1

Substituting:

\displaystyle m=\frac{9-4}{3+1}=\frac{5}{4}m=3+19−4=45

This value is used in the slope-point form of the line:

\displaystyle y-k=\frac{5}{4}(x-h)y−k=45(x−h)

Where (h,k) is a point from the table, select for example (3,9):

\displaystyle y-9=\frac{5}{4}(x-3)y−9=45(x−3)

Operate:

\displaystyle y=\frac{5}{4}\cdot x-\frac{5}{4}\cdot 3+9y=45⋅x−45⋅3+9

\displaystyle y=\frac{5}{4}\cdot x+\frac{-15+36}{4}y=45⋅x+4−15+36

The equation of the line is:

\boxed{\displaystyle y=\frac{5}{4}\cdot x+\frac{21}{4}}y=45⋅x+421

Now complete the table.

For x=0:

\displaystyle y=\frac{5}{4}\cdot 0+\frac{21}{4}y=45⋅0+421

y=\frac{21}{4}y=421

For x=15

\displaystyle y=\frac{5}{4}\cdot 15+\frac{21}{4}y=45⋅15+421

\displaystyle y=\frac{75}{4}+\frac{21}{4}=\frac{96}{4}=24y=475+421=496=24

y=24

For y=1.5, find x:

\displaystyle 1.5=\frac{5}{4}\cdot x+\frac{21}{4}1.5=45⋅x+421

Operate:

\displaystyle 1.5-\frac{21}{4}=\frac{5}{4}\cdot x1.5−421=45⋅x

Multiply by 4:

\displaystyle 6-21=5 x6−21=5x

Solve:

x=-15/5=-3x=−15/5=−3
