Answer:

I this a question of some sort?

Answer:

x=-2 solves the equation h(x)=10.

Step-by-step explanation:

Given the function

[tex]h\left(x\right)\:=\:2x^2\:-\:7x-12[/tex]

Putting [tex]h(x)=10[/tex] in the function

[tex]10=2x^2-7x-12[/tex]

switch both sides

[tex]2x^2-7x-12=10[/tex]

add 12 to both sides

[tex]2x^2-7x-12+12=10+12[/tex]

[tex]2x^2-7x=22[/tex]

Divide both sides by 2

[tex]\frac{2x^2-7x}{2}=\frac{22}{2}[/tex]

[tex]x^2-\frac{7x}{2}=11[/tex]

Rewriting in the form x²+2ax+a²

[tex]\mathrm{Add\:}\left(-\frac{7}{4}\right)^2\mathrm{\:to\:both\:sides}[/tex]

[tex]x^2-\frac{7x}{2}+\left(-\frac{7}{4}\right)^2=11+\left(-\frac{7}{4}\right)^2[/tex]

[tex]x^2-\frac{7x}{2}+\left(-\frac{7}{4}\right)^2=\frac{225}{16}[/tex]

[tex]\left(x-\frac{7}{4}\right)^2=\frac{225}{16}[/tex]

[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]

slove

[tex]x-\frac{7}{4}=\sqrt{\frac{225}{16}}[/tex]

[tex]x-\frac{7}{4}=\frac{\sqrt{225}}{\sqrt{16}}[/tex]

[tex]x-\frac{7}{4}=\frac{15}{4}[/tex]

[tex]\mathrm{Add\:}\frac{7}{4}\mathrm{\:to\:both\:sides}[/tex]

[tex]x-\frac{7}{4}+\frac{7}{4}=\frac{15}{4}+\frac{7}{4}[/tex]

[tex]x=\frac{11}{2}[/tex]

solving

[tex]x-\frac{7}{4}=-\sqrt{\frac{225}{16}}[/tex]

[tex]x-\frac{7}{4}=-\frac{15}{4}[/tex]

[tex]\mathrm{Add\:}\frac{7}{4}\mathrm{\:to\:both\:sides}[/tex]

[tex]x-\frac{7}{4}+\frac{7}{4}=-\frac{15}{4}+\frac{7}{4}[/tex]

[tex]x=-2[/tex]

The solutions to the quadratic equation are:

[tex]x=\frac{11}{2},\:x=-2[/tex]

Therefore, x=-2 solves the equation h(x)=10.

Answer:

one solution

Step-by-step explanation:

Given

9(3x - 5) = - 9(- 5x - 3) ← distribute parenthesis on both sides )

27x - 45 = 45x + 27 ( subtract 45x from both sides )

- 18x - 45 = 27 ( add 45 to both sides )

- 18x = 72 ( divide both sides by - 18 )

x = - 4

Answer:

It takes more time on moon for the rock to fall.

Step-by-step explanation:

Given that:

Time it takes for rock to fall d meters on earth = √0.45d

Time it takes for rock to fall d meters on moon = √1.11d

For a rock to fall 50 meters:

On earth :

Time = √0.45*50 = 4.7434164 seconds

On moon :

Time = √1.11*50 = 7.4498322 seconds

Time on moon > Time on earth

Hence, It takes more time on moon for the rock to fall.

Answer:

Ana runs at a speed of 7.5 miles per hour

Step-by-step explanation:

Speed

Is the rate at which the distance changes in time.

The formula to calculate the speed is:

[tex]\displaystyle v=\frac{d}{t}[/tex]

Where d is the distance traveled in time t.

We know Ana runs a distance of d=3/4 miles in 6 minutes, already converted to t=1/10 hours.

Thus, the speed is calculated as follows:

[tex]\displaystyle v=\frac{\frac{3}{4}}{\frac{1}{10}}[/tex]

Multiplying by the reciprocal of the denominator:

[tex]\displaystyle v=\frac{3}{4}\cdot \frac{10}{1}=\frac{30}{4}[/tex]

v=7.5 mile/h

Ana runs at a speed of 7.5 miles per hour

Im so sorry. Your question is very poorly formatted I do not understand what you are saying.

The GCF of 34 and 51 is 17

Answer:

x<2

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Given

56 - 10x > 20 + 8x ( add 10x to both sides )

56 > 20 + 18x ( subtract 20 from both sides )

36 > 18x ( divide both sides by 18 )

2 > x , thus

x < 2 → D

Answer:

if its 24 by 36 then its 150%. If it was 36 by 24 then it would be 66.6

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

x3(−5x+4)+5x−1=−39

−5x4+4x3+5x−1=−39

Step 1: Subtract -39 from both sides.

−5x4+4x3+5x−1−(−39)=−39−(−39)

−5x4+4x3+5x+38=0

Step 2: Factor left side of equation.

(−x+2)(5x3+6x2+12x+19)=0

Step 3: Set factors equal to 0.

−x+2=0 or 5x3+6x2+12x+19=0

x=2 or x=−1.409699

Answer:

x = 17

Step-by-step explanation:

Since it shows that the diagram is corresponding angles, we can set them equal to each other.

8x + 20 = 11x - 31

-3x = -51

x = 17 degrees

Answer:

m= -3

b= 4

Step-by-step explanation:

whatever number has x next to it is always slope, that is how you find slope in a equation. To find y-intercept (b) you can just use the other number that doesn't have x to it.

Hi, you've asked an incomplete question. Here are the remaining questions:

a) Describe what each region in the Venn diagram represents.

Region I: In drama club, not in step team.

Region II: In both clubs.

Region III: In step team not in drama.

Region IV: Not in either club.

b) How many students were in only one of the two clubs?

c) How many students were in the drama club or in the step team?

d) How many students were surveyed?

Attached is the Venn diagram depicting the regions.

Explanation:

b) By adding the number of students that like drama club and those that like step club we can derive the answer:  34 + 27 = 61.

c) By adding 34 + 27 + those that like both (14) = 75.

d) The total number of students surveyed is gotten by summing any number in attached the diagram: 34 + 27 + 14 + 13 = 88.

Answer:

to go yes back

Step-by-step explanation:

Answer:

(x/12 + 840 + x/8) = 960

576 feets

Step-by-step explanation:

Given that :

Speed to flower bed = 12 ft/s

Speed back to hive = 8 ft/s

Time spent at flower bed = 14 minutes = 14*60.= 840

Total time = 16 mins = (16 * 60) = 960

Let distance between bee hive and flower bed = x

Time taken to flower bed = x / 12

Time taken back to hive = x /8

(x/12 + 840 + x/8) = 960 - - equation

L.C.M of 12 and 8 = 24

(2x + 20160 + 3x)/ 24 = 960

(2x + 20160 + 3x) = 23040

5x = 23040 - 20160

5x = 2880

x = 2880 / 5

x = 576

Distance between flowerbed and hive = 576 feets

Answer:

No, bacause each X (first value), need to have just once Y value (second one). Here you have two values for 3 (4 and 4)

water world give lower priced offer

Step-by-step explanation:

Offer given by Aqua Plus

two-year membership for $479.76

it means,

for 24 month=$479.76
