-3a + 4 = -14
What the answer to this

Answers

Answer 1

Answer:

-6

Step-by-step explanation:

-3a + 4 = -14

-3a = -14 - 4

-3a = -18

a = -18 / 3

a = -6

Answer 2

Answer:

a = 6

Step-by-step explanation:

Step 1: Subtract 4 from both sides.

-3a + 4 - 4 = -14 - 4

+4 and -4 cancel out.

Step 2: Subtract 4 from -14 to get -18.

-3a = -18

Step 3: Divide both sides by -3.

a = -18/-3

Step 4: Divide -18 by -3 to get 6.

a = 6

Let's check our work by substituting a for 6.

-3(6) + 4 = -14

Multiply -3 by 6 to get -18.

-18 + 4 = -14

Add -18 and 4 to get -14.

-14 = -14

This is true, so a = 6.

find all the real and complex zeros of f(x)=x^3-7x^2+4x-28

Answers

Answer:

For [tex]x \in\mathbb{C}[/tex]

[tex]x = -2i[/tex]

[tex]x = 2i[/tex]

[tex]x = 7[/tex]

Step-by-step explanation:

[tex]f(x)=x^3-7x^2+4x-28[/tex]

For [tex]f(x) = 0[/tex]

[tex]x^3-7x^2+4x-28 = 0[/tex]

We can easily factor the expression [tex]x^3-7x^2+4x-28[/tex] by grouping.

[tex]x^3-7x^2+4x-28 = (x^3-7x^2)+(4x-28) = x^2(x-7)+4(x-7) = \boxed{(x^2+4)(x-7) }[/tex]

Now we have

[tex](x^2+4)(x-7) = 0[/tex]

Therefore,

[tex]x^2+4 = 0 \text{ or } x-7 = 0[/tex]

So,

[tex]x^2 = -4 \implies x = \pm\sqrt{-4}[/tex]

Once [tex]\sqrt{-1} = i[/tex]

[tex]x = \pm\sqrt{-4} = \pm\sqrt{4}\sqrt{-1} = \pm 2i[/tex]

Is a 39 Celsius body temperature higher than normal 98 Fahrenheit??

Yes or No

Answers

Answer:

Yes.

Step-by-step explanation:

According to medical science, a body temperature considered normal (that is, below fever) in degrees Fahrenheit is 98ºF, while its equivalent in degrees Celsius is 36.6ºC. Therefore, a body temperature of 39ºC is higher than 98ºF, being equivalent to 102.2ºF.

This is verified by applying the conversion formula from Celcius to Fahrenheit:

(39 x 9/5) + 32 = X

39 x 1.8 + 32 = X

70.2 + 32 = X

102.2 = X

x=25

y= 64.5

Step-by-step explanation:

When lines are parallel, 2x=2(the number)

But, 2 isn't an angle.  However, 50degrees is congruent to 2 since they are verticle angles.

2x=50

x=25

When lines are parallel, 2y+1=1(the number)

But, 1 doesn't have a verticle angle.  However, 180-50 would be equal to 1

180-50=2y+1

130=2y+1

129=2y

y= 64.5

Solve. 3k -4 > 60 – k​

Answers

Answer:

[tex]3k - 4 > 60 - k \\ = 3k + k > 60 + 4 \\ = 4k > 64 \\ = k > \frac{64}{4} \\ = k > 16[/tex]

Answer:

k  > 16

Step-by-step explanation:

Solve it like an equation solving for k

Move the -4 to the other side by adding it to both sides.

3k -4 plus 4  > 60 plus 4 - k

You get 3k > 64 - k

now move the k from the right to the left by adding both sides by k

3k plus k > 64 - k  plus k

You get 4k > 64

Now divide both sides by 4 so you get k alone on one side to solve for the inequality

4k/4 > 64/4

k  > 16
