Answer:

15.

Step-by-step explanation:

5 * - 5 + 40 = 15

Answer:

15

Step-by-step explanation:

f(x) = 5x + 40

Let x = -5

f(-5) = 5(-5) + 40

Multiply

      = -25+40

Add

    = 15

Answer:

Answer: it’s A..

Step-by-step explanation:

No, because it fails the vertical line test.

Given:

y varies directly with x,

It is given that y = 7 when x = -9.

To find:

The value of y when x = 27 for the direct variation.

Solution:

It is given that y varies directly with x, so

[tex]y\propto x[/tex]

[tex]y=kx[/tex]             ...(i)

Where, k is the constant of proportionality.

It is given that y = 7 when x = -9. Putting these values in (i), we get

[tex]7=k(-9)[/tex]

[tex]-\dfrac{7}{9}=k[/tex]

Putting [tex]k=-\dfrac{7}{9}[/tex] in (i), we get

[tex]y=-\dfrac{7}{9}x[/tex]

Putting [tex]x=27[/tex],  we get

[tex]y=-\dfrac{7}{9}(27)[/tex]

[tex]y=-21[/tex]

Therefore, the required value is [tex]y=-21[/tex].

Answer:

  (-2, 5, 7)

Step-by-step explanation:

The problem statement lets us write three equations for the three numbers x, y, and z.

  x + y + z = 10

  -x + 2y = 12

  x - y + 2z = 7

__

Adding the second equation to each of the other two gives ...

  3y +z = 22

  y +2z = 19

Subtracting the second of these from double the first gives ...

  2(3y +z) -(y +2z) = 2(22) -(17)

  6y +2z -y -2z = 44 -19

  5y = 25

  y = 5

  z = 22 -3(5) = 7 . . . . . . from 3y+z=22

  x = 10 -5 -7 = -2 . . . . . .from x+y+z=10

The numbers are (x, y, z) = (-2, 5, 7).

Answer:

The radius of the cylinder is 2.52 cm.

Step-by-step explanation:

The formula for the volume of a cylinder of radius r and height h is

V = πr²h.  We can solve this for r² by dividing both sides of the equation by πh:

r² = V / (πh)

Then the desired radius is found by taking the square root of this.

r = √{V / [πh]}

                  200 cm^2

Here, r² = ------------------- = 6.37 cm^2

                   3.14(10 cm)

and so r = √6.37 cm^2 = 2.52 cm

The radius of the cylinder is 2.52 cm.

Answer:

radius = 2.52 cm

Step-by-step explanation:

[tex]Volume = \pi r^2 h\\\\200 = \pi r^2 \times 10\\\\\frac{200}{10 \times \pi} = r^2 \\\\6.332 = r^2 \\\\\sqrt{6.332} = r \\\\r = 2.52 \ cm[/tex]

Answer:

6.3

Step-by-step explanation:

[tex]6^{2} + 2^{2} = x^{2}[/tex]

40 = [tex]x^{2}[/tex]

[tex]\sqrt{40} = \sqrt{x^{2} }[/tex]

x = 6.3

Answer:

6.3

Step-by-step explanation:

Pythagoras' Theorem (or Pythagorean Theorem) states a²+b²=c², where c is the hypotenuse.

We can use this equation and swap a and b for 6 and 2. This gives 6²+2²=c², which can be expanded to 36+4=c², and further c²=40.

To work out c, we need to square root both sides, leaving c=6.3245553203367586639977870888654, which rounded to 1 decimal place (nearest tenth) is 6.3.

Answer:

g(x) = 0.5x²

Step-by-step explanation:

Since the graph of g(x) still passes through the origin and is u shaped, it is also a quadratic graph but with a different coefficient of x².

Let g(x) = ax²

When x=2, g(x) = 1

Hence, 2a = 1

a = 0.5

Therefore, g(x) = 0.5x²

Answer:

Step-by-step explanation:

Here's my work.

Chang only wanted to spend $44, and the boat costs $8/hr. So, the variable would only be 8t, and you would put 44 on the other side.

Then, you'd put -4 on the side with 8t, because you can take off $4.

So, the setup would be;

44 = 8t - 4.

Answer:

The answer should be A.

Step-by-step explanation:

Given:

The equation is:

[tex]efg-h=i[/tex]

To find:

The value of f.

Solution:

We have,

[tex]efg-h=i[/tex]

We need to isolate f to find the value of f.

Adding h on both sides, we get

[tex]efg-h+h=i+h[/tex]

[tex]efg=i+h[/tex]

Dividing both sides by [tex]eg[/tex], we get

[tex]\dfrac{efg}{eg}=\dfrac{i+h}{eg}[/tex]

[tex]f=\dfrac{i+h}{eg}[/tex]

Therefore, the value of f is [tex]f=\dfrac{i+h}{eg}[/tex].

3) -4 (y - 6)

-4y + 24

4) -5 (2x + 3)

-10x - 15

Answer:

h = -4

Step-by-step explanation:

3(h+6) = 2(-5-2h) Solve for h.

Apply distributive property first on both sides.

3(h+6) = 2(-5-2h)

3h+18 = -10-4h

Next, put the terms with h on one side and the numbers on the other.

3h+18 = -10-4h

7h = -28

Divide both sides by 7 and you have your answer.

7h = -28

h=-4

Answer:

-4

Step-by-step explanation:

First, expand the brackets by multiplying the left bracket all by 3 and the right all by 2. This gives 3h+18=-10-4h.

You want h all on one side, so add 4h to both sides, leaving 7h+18=-10.

Subtract 18 on both sides to leave only h and the coefficient on the left. This gives 7h=-28.

Dividing both sides by 7 isolates the x and gives h=-4.

The mistake is that it is 1/16 not 16. The person probably did the reciprocal or incorrectly used the fraction

Answer:

The exponent for the answer should be -2. Therefore, the answer will be 4⁻² or 1/16.

Step-by-step explanation:

When dividing fractions, you subtract the exponents as long as they have the same base.

Since the exponents both have the base of 4, subtract 9 - 11.

9 - 11 = -2

The exponent would be -2 and the answer would be 4⁻².

When an exponent is negative, you take the inverse of the base raised to the positive exponent.

Since 4² = 16 or 16/1, 4⁻² would be 1/16.

The answer would be 4⁻² or 1/16.

Hope that helps.

Answer:

x = (k-14)/5

Step-by-step explanation:

5x + 14 = k

Subtract 14 from each side

5x + 14-14 = k-14

5x = k-14

Divide by 5

5x/5 = (k-14)/5

x = (k-14)/5

Answer:

k - 14/5

Step-by-step explanation:

5x + 14 = k

On subtracting 14 on both sides,

5x = k - 14

On dividing by 5 on both sides,

x = k - 14/5

Therefore, the value of x = k-14/5
