Which point is located at (-3,-2)?

Answer:

probably B.

Step-by-step explanation:

if he just halves the recipe, then it would still be 1/4 tablespoon because he is making 2 pies.

Answer:

Step-by-step explanation:

Pick the two easiest points to deal with.

(0,4)  and (2,0)

Find m

m = (y2 - y1)/(x2 - x1)

y2 = 4

y1 = 0

x2 =0

x1 = -2

m = (4 - 0)/(0 - - 2)

m = 4/2 = 2

Now use one of the points to find b

y = mx + b        Use (0,4)

4 = 2*0 + b

b = 4

The equation you want is y = 2x + 4

Answer:

? = -2

Step-by-step explanation:

a + b = -2

so, now we need to find all (a + b) combinations in the large expression.

for example, we know

a = -2 - b

or b = -2 - a

and then

-b = 2 + a

but also

3b = -6 - 3a

so that

a - b = a + 2 + a = 2a + 2

therefore

(a + b)(a - b) = a² - b² = -2(2a + 2) = -4a - 4

(-4a - 4 - 12b - 36)/(-4a - 4 - 6a - 6b) =

(-4(a + 3b) - 40)/(-4a - 4 - 6(a + b)) =

(-4(a - 6 - 3a) - 40)/(-4a - 4 - 6×-2) =

(-4(-2a - 6) - 40)/(-4a + 8) =

(8a + 24 - 40)/(-4a + 8) = (8a - 16)/(-4a + 8) =

-2×(-4a + 8)/(-4a + 8) = -2

The number of large frame bought by women are 5 and small frames are 9.

Let 'x' be the number of large frames.

Let 'y' be the number of small frames.

The concepts used is;

money + money = money  and

number of small frames + number of large frames = total number of frames.

Cost of each small frame is $7.

The cost of each large frame is $18.

Total cost is $153.

The system of equations are formed as;

$18y + $7x = $153   ........equation 1.

x + y = 14  

y = 14 - x   .....Put this in equation 1.

$18y + $7x = $153

18(14 - x) + 7x = $153

252 - 18x + 7x = 153

11x = 99

x = 9

y = 14 - 9 = 5

Thus, the number of large frame bought by women are 5 and small frames are 9.

Answer:

54

Step-by-step explanation:

System of equations:

x - y = 3

x + 2y = 21

solving using substitution:

1. isolate one of the variables in one of the equations

x - y = 3

x = 3 + y

2. substitute 3 + y into the other equation

3 + y + 2y = 21

3. simplify

3 + 3y = 21

3y = 18

y = 6

4. substitute 6 back into one of the equations and solve for x

x - 6 = 3

x = 9

Step-by-step explanation:

First, find the slope of side QR. Calculate the slope by finding the ratio of the difference between the y-coordinates and the difference between the x-coordinates of points Q and R.

The slope of side QR can be found as shown below.

Now, using the slope of side QR, draw a triangle RST similar to the right triangle PQR with S(x, 7) as one vertex.

Next, find the value of x as shown below.

Therefore, the value of x in the point (x, 7) is -3.

As per given data area of the top of the rectangular table 21 square feet ,

width [tex]3\frac{1}{2}[/tex] feet the length of the table is equal to 6 feet.

As given,

Area of the top of the rectangular table = 21square feet

Width of the table =  [tex]3\frac{1}{2}[/tex] feet

Let 'l' be the length of the rectangular table

Area = length × width

⇒ 21 =(7/2) × l

⇒l =(21 ×2)/7

⇒l=6feet

Therefore, as per given data area of the top of the rectangular table 21 square feet , width [tex]3\frac{1}{2}[/tex] feet the length of the table is equal to 6 feet.

Answer:

Option A

Step-by-step explanation:

The given piecewise function shows that there is a jump discontinuity at x=1 in the first part of the piecewise function. Hence, this means that for the first part of the piecewise function, x=1 isn't included, but in the second part of the piecewise function, it is.

We can therefore eliminate C and D.

Looking at the first part of the piecewise function, we can see as x grows smaller, y grows larger.  Therefore, A is the more preferred answer because the domain x<1 is valid.

Missing Part:

a. A red ball is drawn

b. A white ball is drawn

Answer:

a. [tex]P(Red) = 0.4375[/tex]

b. [tex]P(White) = 0.3125[/tex]

Step-by-step explanation:

Given

[tex]Red = 7[/tex]

[tex]White = 5[/tex]

[tex]Yellow = 4[/tex]

First, we need to calculate the total

[tex]Total = Red + White + Yellow[/tex]

[tex]Total = 7+5+4[/tex]

[tex]Total = 16[/tex]

Solving (a): Probability of Red.

This is calculated by dividing number of red balls by the total

So:

[tex]P(Red) = \frac{Red}{Total}[/tex]

[tex]P(Red) = \frac{7}{16}[/tex]

[tex]P(Red) = 0.4375[/tex]

Solving (a): Probability of White.

This is calculated by dividing number of white balls by the total

So:

[tex]P(White) = \frac{White}{Total}[/tex]

[tex]P(White) = \frac{5}{16}[/tex]

[tex]P(White) = 0.3125[/tex]

Answer:

Raul performed better in the biology test

Step-by-step explanation:

Given

History

[tex]Score = 80[/tex]

[tex]Mean = 70[/tex]

[tex]Standard\ Deviation = 10[/tex]

Biology

[tex]Score = 75[/tex]

[tex]Mean = 70[/tex]

[tex]Standard\ Deviation = 2.5[/tex]

Required

Where did he perform better relative to other students

To do this, we simply calculate the z score in both tests and make comparison.

z score is calculated as thus;

[tex]z = \frac{x - Mean}{SD}[/tex]

For history;

[tex]z = \frac{80 - 70}{10}[/tex]

[tex]z = \frac{10}{10}[/tex]

[tex]z = 1[/tex]

For biology;

[tex]z = \frac{75 - 70}{2.5}[/tex]

[tex]z = \frac{5}{2.5}[/tex]

[tex]z = 2[/tex]

Since the z score in the biology test is greater than that of the history test, then he performed better in the biology test
