Answer 1
Answer:

Answer:

3. x = 5

4. -5 1/25

Step-by-step explanation:

-3x+5=-10

Subtract the 5 from both sides...

-3x = -15

Divide by -3

x = 5

For 4, it's just multiplying.

-2 4/5 in improper form is -14/5

1 4/5 in improper form is 9/5

-14/5 x 9/5 is -126/25

-126/25 can be -5.04 or -5 1/25.

Answer 2
Answer:

Answer:

3. a (x=5)

4. -126/25

Step-by-step explanation:

3. -3x+5=-10

-3x=-10-5

-3x=-15

x=5

4.  -(-2 4/5) x 1 4/5

(-14/5) x 9/5

= -126/25

For the function f(x) = -2(x + 3)^2 -1, identify the vertex, domain, and range. A.) The vertex is (3, -1), the domain is all real numbers, and the range is y ≥ -1. B.) The vertex is (3, -1), the domain is all real numbers, and the range is y ≤ -1. C.) The vertex is (-3, -1), the domain is all real numbers, and the range is y ≤ -1. D.) The vertex is (-3, -1), the domain is all real numbers, and the range is y ≥ -1

Answers

ok so domain is all allowed numbers look at deonomenator and don't allow any numbers that will make it zero none that means domain=all real numbers vertex in form y=a(x-h)^2+k (h,k)=vertex we have y=-2(x+3)^2-1 h=-3 k=-1 vertex=(-3,-1) range the vertex opens down so max is y=-1 y≤-1 domain is all real vertex is (-3,-1) y≤-1 C

Answer:

3 pigs

Step-by-step explanation:

First split the shape into two rectangles to find the area. On the left you can make the rectangle 10*7 and on the right subtract 7 from 16 to get 9 so the one on the right is 9*6. Find the area of both rectangles by multiplying, which will get you 70 and 54 respectively. Add these to get 124 square meters of space in the field. Now you will have to divide it by 36 to see how many pigs can fit, which results in the answer 3.4444... Round down to get 3 pigs as you can not fit another pig in the .4444... of space.

What are the approximate solutions of 2x2 − 7x = 3, rounded to the nearest hundredth?A: No real solutions
B: x ≈ −0.77 and x ≈ 7.77
C: x ≈ −0.39 and x ≈ 3.89
D: x ≈ −3.89 and x ≈ 0.39

Answers

Answer:

Option C is the correct option.

Step-by-step explanation:

The given equation is 2x² - 7x - 3 = 0

In this quadratic equation we will use quadratic formula to get the roots of x.

x=\frac{-b\pm \sqrt{b^(2)-4ac}}{2a}

By putting values of a = 2, b = -7 and c = -3 in the quadratic formula

x=\frac{7\pm \sqrt{(-7)^(2)-4* 2* (-3)}}{2* 2}

=(7\pm √(49+24))/(4)

=(7\pm √(73))/(4)

Now we get two values for x

x=(7+√(73))/(4)

=(7+8.54)/(4)=3.89

and x=(7-√(73))/(4)

=(7-8.54)/(4)

=-(1.54)/(4)=-0.39

Therefore option C. is the answer.

The approximate solutions of equation 2x² - 7x = 3 are,

C: x ≈ −0.39 and x ≈ 3.89

We have to given that,

An expression is,

⇒ 2x² - 7x = 3

Now, We can find the approximate solutions of equation as,

⇒ 2x² - 7x = 3

⇒ 2x² - 7x - 3 = 0

By using quadratic formula, we get;

⇒ x = - (- 7) ± √(- 7)² - 4×2×- 3 / (2×2)

⇒ x = (7 ± √49 + 24) / 4

⇒ x = (7 ± √73) / 4

⇒ x = (7 ± 8.5) / 4

This give two solutions,

⇒ x = (7 - 8.5) / 4

⇒ x = - 1.5 / 4

⇒ x = - 0.39

⇒ x = (7 + 8.5) / 4

⇒ x = 15.5 / 4

⇒ x = 3.89

Therefore, The approximate solutions of equation 2x² - 7x = 3 are,

C: x ≈ −0.39 and x ≈ 3.89
