Answer: He's wrong. The solution is x=2

Step-by-step explanation:

4x-4=12-4x

8x-4=12

8x=16

x=2

Blake's assumption is wrong. x = 2 is the solution.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

We have an algebraic equation,

4(x − 1) = 12-4x.

Simplifying,

4x - 4 = 12 - 4x

8x = 16

x = 2

Therefore, x = 2 is the solution.

Answer:

11.7

Step-by-step explanation:

Step 1: Our output value 39.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 39 = 100%.

Step 4: Similarly, x = 30%.

Step 5: This results in a pair of simple equations:

39 = 100%(1)

x = 30%(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

39/x = 100%/30%

Step 7: Again, the reciprocal of both sides gives

x/39 = 30/100

------> x = 11.7

Therefore, 30% of 39 is 11.7

Answer:

N = 17.1°

P = 72.9°

168.96 = NQ

Step-by-step explanation:

13.6 ^2 = 4^2 + NQ

184.96 - 16 = NQ

168.96 = NQ

------------------------

N = 17.1°

P = 72.9°

Answer:

(a) [tex]x=-2,3[/tex] (b) [tex]x=\frac{3}{4} ,-\frac{11}{4}[/tex]

Step-by-step explanation:

[tex]y=x^2-x-6\\y=2x^2+x-6[/tex]

For the first equation, this can easily be factored

[tex]y=(x+2)(x-3)[/tex]

Now, set each of their factors equal to zero and solve

[tex]x+2=0\\x=-2\\\\x-3=0\\x=3[/tex]

Therefore, for a, the roots of [tex]y=x^2-x-6[/tex] are [tex]x=-2, 3[/tex]

For the second equation, it is able to be factored, however, its normally easier to use the quadratic equation to solve polynomials with an a term greater than 1

[tex]y=2x^2+x-6[/tex]

[tex]x_{1} =-b+\frac{\sqrt{b^2-4ac} }{2a}=-1+\frac{\sqrt{1-4(2)(-6)} }{4}=-1+\frac{\sqrt{1-(-48)} }{4}=-1+\frac{\sqrt{49} }{4} =-1+\frac{7}{4}=\frac{3}{4}[/tex]

[tex]x_{2}=-b-\frac{\sqrt{b^2-4ac}}{2a}=-1-\frac{\sqrt{1-4(2)(-6)} }{4} =-1-\frac{\sqrt{1-(-48)} }{4}=-1-\frac{\sqrt{49} }{4}=-1-\frac{7}{4} =-\frac{11}{4}[/tex]

Step-by-step explanation:

i just searched it up

1). 2/3 ÷ 3/6

=> 2/3 ÷ 3/6

=> 2/3 × 6/3

=> 2/1 × 2/3

=> 4/3

2). 1/5 + 3/4

=> 1/5 + 3/4

=> 1 × 4/5 × 4 + 3 × 5/4 × 5

=> 4/20 + 15/20

=> 4 + 15/20

=> 19/20

3). 15/3 × 21/5

=> 15/3 × 21/5

=> 15 × 21/3 × 5

=> 315/15

=> 21 × 15/1 × 15

Answer:

85°

Step-by-step explanation:

The sum of all angles in a triangle is 180°

180 = y + 37 + 58

y = 180 - 37 - 58

y = 85

Answer:

85 degrees

Step-by-step explanation:

y+95 degrees=180 degrees

y=85 degrees

Answer:

x=−2 or x=4

Step-by-step explanation:

Step 1: Subtract x+2 from both sides.

x2−x−6−(x+2)=x+2−(x+2)

x2−2x−8=0

Step 2: Factor left side of equation.

(x+2)(x−4)=0

Step 3: Set factors equal to 0.

x+2=0 or x−4=0

x=−2 or x=4

20% off means it is selling for 80% of the original price (109% - 20 % = 80%)

Sale price = 6600 x 0.80 = 5,280

Now add the tax:

5280 x 1.05 = 5544

Answer:

  not generally

Step-by-step explanation:

The basic log function has a vertical asymptote where its argument is zero. It has a positive slope for all positive arguments. It tends to infinity as the argument tends to infinity. There is no horizontal asymptote.

__

A log function can be made part of a larger expression in a way that would give the expression a horizontal asymptote. For example, the function ...

  f(x) = 1/log(x)

has a horizontal asymptote at f(x) = 0. (This asymptote is approached very slowly.)
