Pretend the underline is a division line.

The square root symbol (√) counts for everything after it, not just b² btw.

Answer:

-6,-9,-20,-25.

Step-by-step explanation:

You need to multiply a negative to make it positive as a negative multiplied by a negative equals a positive. But anything besides -1,-2,-3,-4,-5 and all positves can be placed.

Step-by-step explanation:

Given:

The length of the rectangle = [tex]y^2+3y+7[/tex]

Width of the rectangle = [tex]y-3[/tex]

To find:

How much longer is the length?

Solution:

We need to find the difference between length and width of the rectangle.

[tex]Difference=Length-Width[/tex]

[tex]Difference=y^2+3y+7-(y-3)[/tex]

[tex]Difference=y^2+3y+7-y+3[/tex]

[tex]Difference=y^2+(3y-y)+(7+3)[/tex]

[tex]Difference=y^2+2y+10[/tex]

Therefore, the length of the rectangle is [tex]y^2+2y+10[/tex] much longer than the width.

Answer:

Step-by-step explanation:

Find the slope of each line. If the slopes are the same, the lines are parallel. Otherwise, the lines intersect.

Slope of line passing through (x₁, y₁) and (x₂, y₂) = (y₂-y₁)/(x₂-x₁)

Slope of line passing through (0, 5) and (-6, 3) = (3-5)/(-6-0) = ⅓

Slope of line passing through (-15, 0) and (-21, -2) = (-2-9)/(-21-(-2)) = 11/19

The lines intersect.

Answer: Annie needs 13 quarts of coffee

Answer:

Step-by-step explanation:

28 students all give $128

so,

[tex]\sqrt[28]{128}[/tex]= v  v=6

Each student gave 6 dollars. This is true due to the fact that

[tex]\sqrt[28]{128}[/tex]=6

28X6=128

3x+3x+x+x=400

8x=400

x=400÷8

x=50

Answer:

a) IJ is median

b) I is midpoint of HE, therefore, HI = IE

Substitute values and solve for x:

Answer:

a) IJ is median

IJ = 1/2(HG + EF)

IJ = 1/2(8 + 12) = 10 cm

b) I is midpoint of HE, therefore, HI = IE

Substitute values and solve for x:

10 = x - 4

x = 10 + 4

x = 14 cm

Answer:

1) The vertices of the hyperbola are (-8, -15), (-8, 3)

2) The foci of the hyperbola are (11, -7) or (1, -7)

Step-by-step explanation:

1) The vertices of a hyperbola given in the form [tex]\dfrac{\left (y - k\right)^2}{a^2} -\dfrac{\left (x - h\right)^2}{b^2} = 1[/tex] is (h, k ± a)

Therefore, for the given hyperbola with the following equation;

[tex]\dfrac{\left (y + 6\right)^2}{81} -\dfrac{\left (x + 8\right)^2}{49} = 1[/tex], we have;

[tex]\dfrac{\left (y + 6\right)^2}{9^2} -\dfrac{\left (x + 8\right)^2}{7^2} = 1[/tex]

Therefore the vertices are;

(-8, -6 ± 9) = (-8, -15), (-8, 3)

2) The equation of the given hyperbola is presented as follows;

[tex]\dfrac{\left (x - 6\right)^2}{16} -\dfrac{\left (y + 7\right)^2}{9} = 1[/tex]

The given hyperbola is of the form;

[tex]\dfrac{\left (x - h\right)^2}{a^2} -\dfrac{\left (y - k\right)^2}{b^2} = 1[/tex]

We get;

[tex]\dfrac{\left (x - 6\right)^2}{4^2} -\dfrac{\left (y + 7\right)^2}{3^2} = 1[/tex]

The foci is then (h ± c, k)

Therefore, by comparison, the foci of the given hyperbola is (6 ± c, -7)

Where c² = a² + b²

∴ c² = 4² + 3² = 25

c = √25 = 5

∴ The foci; (6 ± 5, -7) = (11, -7) or (1, -7).

Answer:

see explanation

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and are supplementary, sum to 180° , so

5x + x + 54 = 180 ← equation to solve to find x

6x + 54 = 180 ( subtract 54 from both sides )

6x = 126 ( divide both sides by 6 )

x = 21

Then

∠ 1 = 5x = 5 × 21 = 105°

∠ 2 = x + 54 = 21 + 54 = 75°

Answer is 15 miles

This is because:

1 inch- 5 miles

3 inches- 15 miles

3x5=15 miles
