Answer:

y > -3x + 6

Step-by-step explanation:

The y intercept is the first thing we look at and its super easy. so its 6

now we have to find the slope.

well since 2 is x and 6 is y its 6/2 well simplify this its 3. but now its going downwards like so in the graph it is -3. it would be 3 if it wasn't a decline. so since the shading is above the line it is this symbol >

if you have any questions feel free to ask in the comments.

Solve the equation.<br><br> 42x – 5 = 64

aliina [53]

Answer:

23/14

Step-by-step explanation:

42x - 5 = 64

Add 5 to both sides in order to isolate 42x

42x = 64 + 5

42x = 69

Divide 42 from both sides in order to isolate x

x = 69/42

The answer gives an uneven decimal so it'd be best to leave it as a simplified fraction. The simplified fraction is 23/14.

What is the value of x ? 6.75 + 3/8x = 13 1/4

Bad White [126]

Let's solve your equation step-by-step.

6.75+38x=1314

Step 1: Simplify both sides of the equation.

38x+6.75=534

Step 2: Subtract 6.75 from both sides.

38x+6.75−6.75=534−6.75

38x=132

Step 3: Multiply both sides by 8/3.

(83)*(38x)=(83)*(132)

x=523

Answer:

x=1713

باستعمال log4 2=0.5 فإن قيمة log4 32 هي

11Alexandr11 [23.1K]

Answer:

$\mathbf{\log_432}=2.5$

Step-by-step explanation:

$\log_42=0.5$

حن بحاجة إلى إيجاد $\log_432$

دع $\log_432=x$

$\log_42\times 2\times 2\times 2\times 2=x$

$\Rightarrow x=\log_42^5$

$\Rightarrow x=5\log_42$ $[\because \log_ab^x=x\log_ab]$

$\Rightarrow x=5\times0.5$

$\Rightarrow x=2.5$

$\mathbf{\therefore\log_432=2.5}$

Which is a solution to 2x + 1 = 21?

Bezzdna [24]

Answer:

x = 10 is your answer

- Explain -

Step 1: subtract 1 from both sides (subtraction of equality)

which will give us:

2x = 21 - 1

which equals to

2x = 20

Step 2: Divide both sides by 2

which is

2x/2 = 20/2

2/2 = 1 and 20/2 = 10

Therefore the answer is x = 10
