Answer:

x ≈ - 5.32, x ≈ 1.32

Step-by-step explanation:

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt{11}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{11}[/tex]

Thus

x = - 2 - [tex]\sqrt{11}[/tex] ≈ - 5.32 ( to 2 dec. places )

x = - 2 + [tex]\sqrt{11}[/tex] ≈ 1.32 ( to 2 dec. places )

Answer:

x = -5.32, x = 1.32

Step-by-step explanation:

Ok. So to use the Complete the Square method, you divide the middle value by 2 and then square the number you get. This will give:

[tex](x^{2} + 4x + (\frac{4}{2}) ^2) - (\frac{4}{2}) ^2 -7 = 0[/tex]

[tex](x^{2} + 4x + 4) - 4 -7 = 0[/tex]

[tex](x^{2} + 4x + 4) - 11 = 0[/tex]

[tex](x^{2} + 4x + 4) = 11[/tex]      (now factor the left side)

[tex](x + 2)(x + 2) = 11[/tex]

[tex](x + 2)^{2} = 11[/tex]       (now square root both sides)

[tex]\sqrt{(x + 2)^{2}} = \sqrt{11}[/tex]

[tex]x + 2 = \sqrt{11}[/tex]

[tex]x = - 2 +/- \sqrt{11}[/tex]         (+/- = plus or minus)

x = -5.32, x = 1.32

Answer:

Step-by-step explanation:

10). AD = BC [If ABCD is a parallelogram]

     3x + 1 = 6x - 4

     6x - 3x = 1 + 4

     3x = 5

     x = [tex]\frac{5}{3}[/tex]

11). If ABCD is a parallelogram,

     AB = CD

     5x - 8 = 2x + 7

     5x - 2x = 7 + 8

     3x = 15

     x = 5

12). If ABCD is a parallelogram,

     AB = CD

     AB║CD and BD is a transversal intersecting these parallel lines.

     ∠ABD ≅ ∠BDC [Alternate interior angles]

     4x - 1 = x + 38

     4x - x = 38 + 1

     3x = 39

     x = 13

9514 1404 393

Answer:

  10 ft

Step-by-step explanation:

The slope is rise/run. Using Gary's numbers, we have ...

  m = rise/run

  0.375 ≥ (3.75 ft)/run

  run ≥ (3.75 ft)/0.375

  run ≥ 10 ft

The shortest horizontal distance to the base of the ramp is 10 feet.

The answer to this question is 32

Explanation

16/30 cross multiplies x/60

after you get, 960=30x

then divide by 30 and then you get 32.

or you can just take 16 and multiply it by two since 60 is a multiple of 30.

Answer:

i am sorry i do not understand ill try to look harder ill keep u updated

Step-by-step explanation:

Answer: 27.7 millimeters

Step-by-step explanation:

Let the missing leg be represented by x.

We will use Pythagoras formula to solve this. The measure of the missing leg will be:

x² = 37² - 24.5²

x² = 1369 - 600.25

x² = 768.75

x = ✓768.75

x = 27.7

The missing leg is 27.7 millimeter

Answer:

22.5 miles

Step-by-step explanation:

There are 3, 20 minute increments in an hour, and 1 and a half 20 minute increments in half an hour, so, you simply add 3 + 1.5 which equals 4.5.

Then, multiply 5 (miles) by 4.5 to get 22.5 (miles).

Answer:

2p^2-p + 5/2

Step-by-step explanation:

Here, we want to use long division method

Please check attachment for the long division process

According to the long division, the answer is

2p^2-p + 5/2

To check the answer, we multiply the binomial by the result of the division

That will be;

(2p-1)(2p^2-p + 5/2)

= 4p^3-2p^2+5p-2p^2+p-5/2

= 4p^3-2p^2-2p^2+5p+p-5/2

= 4p^3-4p^2+ 6p - 5/2

we then conclude that our answer is correct

Answer:

m (slope) = 664

Step-by-step explanation:

Formula:

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

m = 16570 - 21226 / 1982 - 1986

= -4,656 / -4

= 664

Answer:

$206.25

Step-by-step explanation:

Regular price of item = R= $375

Price after 45% off = (1-0.45) x 375

                               =$ 206.25

Step-by-step explanation:

General line equation: y = mx + c

When x = 0, y = 3. => (3) = m(0) + c, c = 3.

When x = -4, y = 5. => (5) = m(-4) + c,

5 = -4m + (3), -4m = 2, m = -0.5.

Hence the answer is y = -0.5x + 3.

Answer:

y=-[tex]\frac{1}{2}[/tex]+3

Step-by-step explanation:

To write the equation of the line in slope-intercept form, first calculate the slope of the line (m)

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

=[tex]\frac{5-3}{-4-0}[/tex]

=2/-4

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

next, calculate b by substituting a point (0, 3) into the equation

y=mx+b

3=(-1/2)(0)+b

b=3

final equation of line is: y=-[tex]\frac{1}{2}[/tex]+3

Answer:

The slope of a line that is perpendicular to the x-axis ​is undefined.

Step-by-step explanation:

We know that the x-axis is a horizontal line.

Therefore, the slope of a line that is perpendicular to the x-axis ​is undefined.

For example, the slope between (1, 2) and (1, 4) is:

Using the slope formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 = [4 - 2] / [1 - 1]

                  = 2 / 0

                  = ∞
