Which numbers below are solutions to the inequality 4y+3≤−7?

Answer:

q1 (1,-3)

r1 (3,3)

s1 (0,2)

t1 (-2,-1)

Step-by-step explanation:

When a shape is reflected, it must be reflected across a line

The vertices for [tex]\mathbf{rx-axis}[/tex] of qrst are:

The given parameters are:

[tex]\mathbf{q = (1,3)}[/tex]

[tex]\mathbf{r = (3,-3)}[/tex]

[tex]\mathbf{s = (0,-2)}[/tex]

[tex]\mathbf{s = (-2,1)}[/tex]

The transformation rule is given as:

[tex]\mathbf{rx-axis}[/tex]

The above rule means that the vertices are reflected over the x-axis

The rule of the transformation is:

[tex]\mathbf{(x,y) \to (x,-y)}[/tex]

So, we have:

[tex]\mathbf{q(1,3) \to q'(1,-3)}[/tex]

[tex]\mathbf{r(3,-3) \to r'(3,3)}[/tex]

[tex]\mathbf{s(0,-2) \to s'(0,2)}[/tex]

[tex]\mathbf{t(-2,1) \to t'(-2,-1)}[/tex]

Hence, the vertices for [tex]\mathbf{rx-axis}[/tex] of qrst are:

[tex]\mathbf{q'(1,-3)}[/tex]

[tex]\mathbf{ r'(3,3)}[/tex]

[tex]\mathbf{ s'(0,2)}[/tex]

[tex]\mathbf{t'(-2,-1)}[/tex]

Answer:

5 drahms.

Step-by-step explanation:

From the question given above, the following data were obtained:

120 grains = 6 scruples

6 scruples = 2 drahms

300 grains (in drahms) =..?

From the above data,

120 grains = 6 scruples

6 scruples = 2 drahms

Therefore,

120 grains = 2 drahms

Thus, we can obtain 300 grains in drahms as follow:

120 grains = 2 drahms

Therefore,

300 grains = 300 grains × 2 drahms /120 grains

300 grains = (300 × 2)/120 drahms

300 grains = 5 drahms

Therefore, 300 grains is equivalent to 5 drahms.

Answer:

The answer is c

Step-by-step explanation:

Answer:

Solve for each exponent.

3^4 is 81.

3^7 is 2187.

So the fraction is 81/2187.

Now we need to simplify it.

That's 1/27.

C is the correct answer to the problem.

Answer:

Step-by-step explanation:

[tex]a + \frac{1}{2}=4\\\\[/tex]

     [tex]a = 4 -\frac{1}{2}\\\\a =\frac{4*2}{1*2}-\frac{1}{2}\\\\a =\frac{8}{2}-\frac{1}{2}\\\\a=\frac{7}{2}[/tex]

[tex]\frac{1}{a}=\frac{1}{\frac{7}{2}}\\\\ = 1*\frac{2}{7}\\\\ = \frac{2}{7}[/tex]

[tex]a^{3}+\frac{1}{a^{3}}=(\frac{7}{2})^{3}+(\frac{2}{7})^{3}[/tex]

Step-by-step explanation:

let the number be x

=7+x

=3(7+x)

=3(7+x)-2

13=3(7+x)-2

solving for  x we have

13=21+3x-2

21+3x-2-13=0

collect like terms we have

21-2-13+3x=0

6+3x=0

6=-3x

x=6/-3

Answer:

She can serve up to 22 people

Step-by-step explanation:

Given that the total amount of soup that Joy makes in liters is 6.5L

also that the portions are in ml

280ml to liters we have 280/1000= 0.28L

our aim is to know weather 6.5L divided by 0.28L  can be up to 22

let us try it out

6.5/0.28= 23.214

we have 23.

Therefore the 6.5L can serve up to 22 portions of  280ml in 6.5 L of soup

A small bottle costs $14.

To solve the problem, the equation would be this:

Let s represent a small bottle. Since one large bottle is $4 more than a small one, you would write out (4+s). Then, multiply it by 8 to find one side of the equation, and get 8(4+s). To write out the right side of the equation, you would write out 12s to represent 12 small bottles, and subtract 24 from that to represent that 8 large bottles is $24 less than 12 small ones.

Then, proceed to solve the equation to get the answer of s=14. Because a small bottle is $14, you can check your work by substituting the 14 in replace of s. :

Answer:

The answer is 5³.

Step-by-step explanation:

You have to apply Indices Law :

[tex] {a}^{m} \times {a}^{n} ⇒ {a}^{m + n} [/tex]

[tex] {a}^{m} \div {a}^{n}⇒ {a}^{m - n} [/tex]

[tex] { ({a}^{m} )}^{n} = {a}^{mn} [/tex]

So for this question :

[tex]( {( {5}^{2}) }^{3} \times {5}^{4} ) \div {5}^{7} [/tex]

[tex] = ( {5}^{6} \times {5}^{4} ) \div {5}^{7} [/tex]

[tex] = {5}^{10} \div {5}^{7} [/tex]

[tex] = {5}^{3} [/tex]

Answer:

(w + 3) [7w²  - 3]

Step-by-step explanation:

Given expression:

    7w²(w + 3) - 3(w + 3);

 Now rewriting the equation by factoring out (w+ 3);

 Solution:

   7w²(w + 3) - 3(w + 3);

   = (w + 3) [7w²  - 3]

The solution is (w + 3) [7w²  - 3]

Totals to 100.53cm^2

C = pi X 8 = 25.133

Area = 25.133 X 15 = 376.995cm^2

100.53+376.995= 477.525cm^2.

Answer:

Step-by-step explanation:

P(y) = y³ + 2y² + 2y + 1  

P(-1) = (-1)³ + 2*(-1)² + 2*(-1) + 1

      = -1 + 2 - 2 + 1

      = 0

As, P(-1) = 0, (y + 1) is a factor.

  Use synthetic division or remainder theorem.

-1        1          2           2           1

           0        -1            -1         -1        

           1          1            1            0

quotient = y² + y + 1

y³ + 2y² + 2y + 1  = ( y + 1) (y² + y + 1)

Answer:

250 berries

Step-by-step explanation:

Berries : Oranges = 10 : 1

Let the number of berries = x

10 : 1 = x : 25

Product of means = 1*x = x

Product of extremes = 10 * 25 = 250

Product of means =  product of extremes

          x = 250
