slope intercept: y=5x-7

Step-by-step explanation:

first you need slope: y2-y1/x2-x1

-12-3/-1-2=

-15/-3=

5

then plug into this formula: y-y1=m(x-x1)

y-3=5(x-2)

y-3=5x-10

y=5x-7

Answer:

5 packages

Step-by-step explanation:

One package of blackberries cost $3

Let x represent the number of packages that will cost $15

1 = $3

x= $15

3x= 15

Divide both sides by the coefficient of x which is 3

3x= 15/3

x= 5

Hence 5 packages of blackberries will cost $15

Answer:

(5, 0) is the x intercept.

Step-by-step explanation:

Given equation of the line is 2x - 5y = 10

For y-intercept of the line we find the value of y by substituting x = 0 in the given equation.

Similarly, for x-intercept we will substitute the value y = 0 and find the value of x.

2x - 5(0) = 10

2x = 10

x = 5

Therefore, y-intercept of the given line is (5, 0).

Answer:

3 teaspoon

Step-by-step explanation:

If for every 3/4 cup of flour we will need 1/8 teaspoon of salt, then:

1/8 teaspoon = 3/4 cup of flour

To get the amount of teaspoon needed for 18cups we will say:

x teaspoon = 18 cups

Solving both equalities for x:

1/8 teaspoon = 3/4 cup of flour

x teaspoon = 18 cups

Cross multiply

3/4 * x = 18 * 1/8

3x/4 = 18/8

cross multiply again

3x*8 = 4*18

24x = 72

x = 72/24

x = 3

Hence Fran needs 3 teaspoon of salt fir 18cups of flour

Answer:B

Step-by-step explanation:

The coordinates of the image of the rotation of the point Q is:

Q' = (4, 2)

We can see that the original coordinates of point Q are (-4, 0).

If we apply a rotation of 180° about the point (0, 0), it is equivalent to a reflection around the y-axis.

It only changes the sign of the x-component.

Then the image of the rotation is:

Q' = (4, 0)

Answer:

$8,500 in CDs; $11,500 in bonds

Step-by-step explanation:

Let c = amount invested in CDs.

Let b = amount invested in bonds.

"A total of $20,000 is to be invested, some in bonds and some in certificates of deposit (CDs)."

From the total investment, we get this equation.

c + b = 20000

"If the amount invested in bonds is to exceed that in CDs by $3000"

From the details of the amounts, we get this equation.

b = c + 3000

We have a system of equations in two unknowns.

c + b = 20000  Eq. 1

b = c + 3000  Eq. 2

Since Eq. 2 is already solved for b, we will use the substitution method to solve the system of equations.

Substitute b in Eq. 1 with c + 3000.

c + c + 3000 = 20000

2c + 3000 = 20000

2c = 17000

c = 8500

Now substitute c = 8500 in Eq. 2 and solve for b.

b = c + 3000

b = 8500 + 3000

b = 11500

  The null hypothesis is  [tex]H_o : p = 0.67[/tex]

   The alternative hypothesis is  [tex]H_a : p \ne 0.67[/tex]

b

 The sample proportion is [tex]\^ p = 0.65[/tex]

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  546  

      The number of people that use a laptop overnight is  [tex]k = 355[/tex]

    The population proportion is  [tex]p = \frac{2}{3} = 0.67[/tex]

   Generally

  The null hypothesis is  [tex]H_o : p = 0.67[/tex]

   The alternative hypothesis is  [tex]H_a : p \ne 0.67[/tex]

Gnerally the sample proportion is mathematically represented as

        [tex]\^ p = \frac{ k}{n}[/tex]

=>     [tex]\^ p = \frac{ 355}{546}[/tex]

=>     [tex]\^ p = 0.65[/tex]

Answer:

There are two possible locations. E could be located in either -8 or 2.

Step-by-step explanation:

The number line is a one-dimensional graphing model for real numbers, in which each element is represented by points. Under this system, there are two directions:

[tex]-x[/tex] - Left semiaxis that corresponds to negative real numbers.

[tex]+x[/tex] - Right semiaxis that corresponds to positive real numbers.

Both semiaxis are divided by origin, which represents the real number zero.

Let E and F points on the number. If we know that [tex]F = -3[/tex] and [tex]EF = 5[/tex], there are two choices for the location of E. That is:

[tex]E_{1} = F+EF[/tex]

[tex]E_{1} = -3+5[/tex]

[tex]E_{1} = 2[/tex]

[tex]E_{2} = F-EF[/tex]

[tex]E_{2} = -3 -5[/tex]

[tex]E_{2} = -8[/tex]

There are two possible locations. E could be located in either -8 or 2.

Answer:

Range = 13

Mean = 8.3

Variance = 17.61

Step-by-step explanation:

Given the population dataset :

2, 9, 15, 4, 12, 9, 13, 6, 3, 10

1.) Range : (maximum - minimum)

Maximum = 15 ; minimum = 2

Range = (15 - 2) = 13

2.) population mean (μ) :

μ = ΣX / n

n = sample size

μ = (2 + 9 + 15 + 4 + 12 + 9 + 13 + 6 + 3 + 10) / 10

μ = 83 / 10

μ = 8.3

3.) Population variance (s²)

Σ(x - μ)² / n

=[(2 - 8.3)^2 + (9 - 8.3)^2 + (15 - 8.3)^2 + (4 - 8.3)^2 + (12 - 8.3)^2 + (9 - 8.3)^2 + (13 - 8.3)^2 + (6 - 8.3)^2 + (3 - 8.3)^2 + (10 - 8.3)^2] / 10

s² = 176.1 / 10

s² = 17.61

Answer:

Ok so the area of the frame is 18*12 = 216cm^2

Let’s suppose the width of the frame is x

The total area (painting and frame) is (2x+18)(2x+12) and this is equal to 432

4x^2 + 60x + 216 = 432

4x^2 + 60x - 216 = 0

x^2 + 15x - 54 = 0

(x+18)(x-3) = 0

Therefore x = {-18,3}

Since width of the frame has to be positive, the width has to be 3cm Step-
