Answer:

y=1.7x-1.2

Step-by-step explanation:

-10x-17y=14

Subtract 10x to both sides

-17y=-10x+14

Divide by -17 on both sides

y=1.7x-1.2

Answer:

4.93

Step-by-step explanation:

Given 3 numbers a, b and c, the formula for calculating their geometric mean is expressed as:

GM = ∛a*b*c

Given the numbers 4, 5 and 6

geometric mean = ∛4 * 5 * 6

geometric mean = ∛20*6

geometric mean = ∛120

geometric mean = 4.93

Hence the geometric mean is 4.93

Answer:

f(x)= 3x^2+5x

Step-by-step explanation:

f(x)= x(x+1)(x-4)(x+8)

f(x) = x^2 + x + x^2 - 4x + x^2 + 8x

f(x) 3x^2 + 5x

Answer: -2

Step-by-step explanation:

2(h -3.5) = -11 Distributive property

2h - 7 = -11. Add 7 to both sides

2h = -4. Divide both sides by 2

h = -2

Answer: The answer is -2 :)

Step-by-step explanation: 2(h -3.5) = -11  distributive propert

2h-7=-11 Add  -7 to both side

     +7  =+7

2h=-4 Divide 2 to both side

2  =  2

h=-2

Answer:

1 = 7x=42 (divide both sides by 7)

7x/7 =42/7

x=6

2.=9y=81 (divide both sides by 9)

9y/9y= 81/9

y=9

3.= –40=8a (divide both sides by 8)

–40/8= 8a/8

a=5

4.=y divided 11=12

y=11 multiplied by 12

y= 132

5.= –15y=135( divide both sides by –15)

–15y/–15=135/–15

y= –9

6.= 17p=51(divide both sides by 17)

17p/17=51/17

p=3

7.= –65= –13w (divide both sides by 13)

–65/–13=–13w/–13

w=5

8.=y/–2=4

(cross multiply)

y/–2=4/1

4 multiplied by –2= –8

therefore:y= –8

Answer:

a) 7x=42

Step-by-step explanation

use the co-efficient of the unknown to divide both sides

7x=42

7x/7=42/7

x=6

9y=81

9y/9=81/9

y=9

-40=8a

is the same thing as

-8a=40

-8a/-8=40/-8

a=-5

y+11=12

y=12-11

y=1

-15y=135

-15y/-15=135/-15

y=9

17p=51

17p/17=51/17

p=3

-65=-13w

13w=65

13w/13=65/13

w=5

y/-2= 4

cross multiply y=-8

Step-by-step explanation:

Answer:

Step-by-step explanation:

Multiply through the 3 of the first bracket to get 3m +12. Then multiply out the second bracket by -2 to get -8m -2.

Write it out in a line: 3m + 12 - 8m -2

Simplify: -5m +10

Divide by -5 again to simplify further: m - 2

Answer:

=7m+30

Step-by-step explanation:

Distribute:

=(3)(m)+(3)(2)+(4)(6)+(4)(m)

=3m+6+24+4m

Combine Like Terms:

=3m+6+24+4m

=(3m+4m)+(6+24)

=7m+30

Answer:

x ≥ -64

Step-by-step explanation:

"3/4ths of a number is greater than or equal to -48"

3/4 of a number ≥ -48

Let's say the number is x.

(3/4)x ≥ -48

Multiply both sides by 4.

3x ≥ -192

Divide both sides by 3.

x ≥ -64

Answer:

she needs to buy 4 boxes since she can't buy a part of a box. assuming total boxes means completely filled boxes, then she fills 3

Step-by-step explanation:

Answer:

1/33

Step-by-step explanation:

I'm assuming the 3 in 2x3 is an exponent (so hopefully that's what it is...)

When you plug in x and y, the denominator is

2(2)^3 + 3.4(5)

2x2^3= 2^4 which is 16 and 3.4x5= 17

16+17=33

Answer:

-3,-1,0,5,7

Step-by-step explanation:

Answer:

-3,-1,0,5,7

Step-by-step explanation:

Answer:

-1 ≤ x

Step-by-step explanation:

You just need to divide -3 on both sides.

-1 ≤ x

Note that since you are dividing by a negative number, the sign flips.

-1 ≤ x

Step-by-step explanation:

First start with the equation:

3 ≥ -3x

divide by -3 to get x positive and singular:

-1 ≥ x

and since we divided by a negative we need to flip the sign:

-1 ≤ x  would be your answer

Answer:

The value of I for d = 10 will be 1.2 watts/m^3

Step-by-step explanation:

Let I be the intensity of sound and d be the distance

According to given statement, "The intensity of the sound, I watts/m², received from a loudspeaker is  inversely proportional to the square of the distance, d meters, from the  loudspeaker. "

[tex]I \propto \frac{1}{d^2}[/tex]

Removing the proportionality symbol

[tex]I = \frac{k}{d^2}[/tex]

Putting d = 2 and I = 30

[tex]30 = \frac{k}{(2)^2}\\30 = \frac{k}{4}\\k = 30*4\\k = 120[/tex]

Putting the value of k in the equation

[tex]I = \frac{120}{d^2}[/tex]

Putting d = 10

[tex]I = \frac{120}{(10)^2}\\I = \frac{120}{100}\\I = 1.2[/tex]

Hence,

The value of I for d = 10 will be 1.2 watts/m^3

Answer:

[tex]y=-314x-1261[/tex]

Step-by-step explanation:

When we are writing an equation we have to put it in slope-intercept-form [tex]y=mx+b[/tex]. We already know the slope it's -314, we replace m with the slope. Now we have to find b which is the y-intercept. So what we have to do is plug in the ordered pair into the equation. -4 for x and -5 for y.

[tex]y=mx+b\\-5=-314(-4)+b[/tex]

Now we solve

[tex]-5=-314(-4)+b\\-5= 1256+b\\b=-1261[/tex]

So now that we know everything we need we plug in and....

[tex]y=mx+b\\y=-314x-1261[/tex]

we've got our equation!

Answer:

The line slants upward, so the slope is positive.
