What is an angle that is complementary to _1?

Answer:

2) x = [tex]\frac{5+\sqrt{57}}{8}[/tex], [tex]\frac{5-\sqrt{57}}{8}[/tex]

First, you need to begin by rearranging the equation into standard form. This would result to [tex]-4x^{2}[/tex]+5x+2. Because the first term cannot be a negative, you need to multiply the equation by -1, in order to eliminate the negative. This would result with [tex]4x^{2}[/tex]-5x-2.

There are many different methods when factoring a quadratic equation, including X-Method, Factoring by grouping, GCF, Quadratic Formula, etc. In this case, we will utilize quadratic formula. Quadratic formula is [tex]\frac{-b±\sqrt b^{2}-4ac}{2a}[/tex]

Quadratic equations always follow this variable format: [tex]ax^{2}[/tex]+bx+c. By using this format, we can use the corresponding numbers to solve the quadratic formula. This would result with [tex]\frac{5±\sqrt{-5^{2}-4(4)(-2)}}{2(-4)}[/tex]. Simplify the equation to get [tex]\frac{5±\sqrt{57}}{8}[/tex]. (Ignore the A)

10) C

When looking at [tex]4x^{2}[/tex]-5x-2, the leading coefficient would be 4 and the constant would be -2. The middle coefficient would be -5 and the highest degree would be 2. The answer isn't A, because it's true that the degree is less than the number of terms. (There are 3 terms and the degree is 2.) It isn't B, because it's true that -2 is less than 4. It isn't D, because it's true that -2 is less than -5. The answer is C, because the a-value, 4, is not less than the b-value, -5.

Answer:

Eliminating

Step-by-step explanation:

The given equations are ,

Here I would prefer to use Elimination Method. Since there is negative y and positive y in the equations . So we can eliminate y easily and then we can find x. Also , let's solve ,

On addition :-

→ 2x = -16

→ x = -16/2

→ x = -8

Delta Math

Answer:

50 feet

Step-by-step explanation:

Set up a 3-dimensional coordinate system (see the attached image).

This setup shows an axis that runs North-South (South is negative, North is positive), an axis that runs East-West (East is positive, West is negative), and an axis that runs Up-Down (Up is positive, Down is negative).

The two points in question are then:

First person's location (12, -20, -12), and the second person's location is (-20, 10, 12).

The distance between two points  [tex]\left( x_1,\,y_1,\,z_1\right)[/tex]  and  [tex]\left( x_2,\,y_2,\,z_2\right)[/tex] is

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2[/tex]

[tex]d=\sqrt{(-20-12)^2+(10-(-20))^2+(12-(-12))^2}\\\\d=\sqrt{(-32)^2+30^2+24^2}\\\\d=\sqrt{2500}\\\\d=50[/tex]

Answer:

D. b = 3

Step-by-step explanation:

Given the following data;

Points on x-axis (x1, x2) = 10, 12

Points on y-axis (y1, y2) = 23, 27

First of all, we would determine the slope.

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

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

Substituting into the equation, we have;

[tex] Slope, m = \frac {27 - 23}{12 - 10} [/tex]

[tex] Slope, m = \frac {4}{2} [/tex]

Slope, m = 2

The equation of straight line is y = mx + b

Where;

m is the slope.

x and y are the points

b is the intercept.

To find the intercept, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - 23 = 2(x - 10)

y - 23 = 2x - 20

y = 2x - 20 + 23

y = 2x + 3 = mx + b

Therefore, intercept, b = 3

Problem 1

We all know there are 7 days in a week. How many weeks are in 259 days?

Problem 2

Everyone is given the same number of colored pencils in art class. If there are 249 colored pencils and 8 students, how many pencils does each student receive?

Problem 3

Mr. Hughes has 155 meters of volleyball netting. How many nets can he make if each court requires 9 meters of netting?

Step-by-step explanation:

Answer:

6 bags

Step-by-step explanation:

228 ounces = 18 pounds

18 pounds ÷ 3 pounds

6 bags

-------------------------------------------------------------------------------------------------------------

We all know there are 7 days in a week. How many weeks are in 259 days?

37 weeks

[tex]\frac{1}{7} :\frac{y}{259}[/tex]

y · 7 = 1 · 259

7y = 259

7y ÷ 7 = 259 ÷ 7

y = 37

Everyone is given the same number of colored pencils in art class. If there are 249 colored pencils and 8 students, how many pencils does each student receive?

31 color pencils each and 1 extra pencil

249 ÷ 8 =

31.125 colored pencils each

This rounds to 31 color pencils and 1 extra pencil.

Mr. Hughes has 155 meters of volleyball netting. How many nets can he make if each court requires 9 meters of netting?

7 courts and he will be left with 2 meters of netting

155 ÷ 9

17 and 2/9 volleyball courts

17 courts and he is left with 2 meters of netting.

Answer:

6⅓ ft²

Step-by-step explanation:

Area of the figure = area of a trapezoid

= ½(a + b)h

Where,

a = 11⅓ft = 34/3 ft

b = 34/3 + 15/2 = (68 + 45)/6 = 113/6 ft

h = 6 ft

Plug in the values

Area = ½(34/3 + 113/6)*6

= (34/3 + 113/6)*3

= (68 + 113)/3

= 181/3

= 6⅓ ft²

Answer:

Step-by-step explanation:

A P E X

Answer:

A

Step-by-step explanation:

Equation A is true for all real numbers.  It says the quantity b + 2 is equal to itself!

Equation B, solved for b, gives b = 1, so the equation is true only for b = 1.

Equation C, solved for b, gives 2 = -2, which is absolutely false, so the equation has no solutions.

Equation D, solved for b, gives b = 1, so only one solution

Answer:

V=51, U=90 W= 39

Step-by-step explanation:

V= 51 Degrees (has told in the question)

U= 90 Degrees (Its A Right Angel Triangle, And Right Angle Is Always 90 Degrees)

W= 39 Degrees (Sum Of All Sides Of A Triangle = 180 Degrees

                           51 + 90 + W = 180

                           141 + W = 180

                           W = 180 - 141

                           W = 39 )

Answer:

  9 weeks

Step-by-step explanation:

In problems of this nature, the usual assumption is that the time required is proportional to the work product and inversely proportional to the number of people doing the job. Here, there is no change in the amount of work, but the number of people is reduced by a factor of 12/18 = 2/3.

So, the amount of time required is expected to increase by a factor of 1/(2/3) = 3/2.

Answer:C I got the enge test 90% but this question was correct

Step-by-step explanation:

Answer:

Step-by-step explanation:

we have several angles that have the same vertex and so they are congruent

1) e = 35 degrees because the opp angle has this measure

2) d = 109 degrees for the reason above

3) for find f we have to notice that the sum of the three angles (if you look at the vertical line you can notice that it is a straight line, so describes two angles whose measures are 180 degrees)

f = 180 - (35 + 109)

f = 180 - 144 = 36 degrees
