Answer:

The maximum value is 14.

Step-by-step explanation:

x has to be less than or equal to -2, but x is greater than or equal to -4(This means it can be -2, -3, or -4).

y is greater than or equal to 1, but it is less than or equal to 6(so it can be from 1, 2, 3, 4, 5, or 6.)

The maximum for x is -2 and the maximum for y is 6, so...

5 times -2 equals -10.

4 times 6 is 24.

-10 + 24 = 14.

What is the length of the portion BC of the cloth?

alisha [4.7K]

Answer:

2nd option

Step-by-step explanation:

Using the sine ratio in the right triangle

sin32° = $\frac{opposite}{hypotenuse}$ = $\frac{BC}{AC }$ = $\frac{BC}{6}$ ( multiply both sides by 6 )

6sin32° = BC

Solve 4^x+2 = 12 for x using the change of base formula log base b of y equals log y over log b.

valentinak56 [21]

The value of x is 1.66

Step-by-step explanation:

Let use revise the rules of exponential and logarithmic equations

1. If y = $b^{x}$ , then $log_{b}(y)=x$

2. $log_{b}(y) = \frac{log(y)}{log(b)}$

Use the rules above to solve the problem

∵ $4^{x}+2=12$

- Subtract 2 from both sides

∴ $4^{x}=10$

change the exponential equation to logarithmic equation

∴ $log_{4}(10)=x$

∵ $log_{4}(10) = \frac{log(10)}{log(4)}$

∴ x = $\frac{log(10)}{log(4)}$

∴ x = 1.66

The value of x is 1.66

Someone help me please

Masteriza [31]

Answer:

$(5,1)$

Step-by-step explanation:

Hi there!

Midpoint = $\displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$ where the two endpoints are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in the given information:

Midpoint = (5,3), Endpoint = (5,5)

$(5,3)=\displaystyle (\frac{5+x_2}{2},\frac{5+y_2}{2} )$ where $(x_2,y_2)$ is the other endpoint

Solve for $x_2$ :

$\displaystyle \frac{5+x_2}{2} =5\\\\5+x_2 =10\\x_2 =5$

Solve for $y_2$ :

$\displaystyle\frac{5+y_2}{2}=3 \\\\{5+y_2}=6\\y_2=1$

Therefore, the other endpoint $(x_2,y_2)$ is $(5,1)$ .

I hope this helps!

Find the equation of the line, where P is a point on the graph of the line.<br><br> m=2/3 , P(3,5)

Liula [17]

Answer:

The answer is

$y = \frac{2}{3} x + 3$

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To write an equation of a line given a point and slope we have

y - y1 = m( x - x1)

where (x1 , y1 ) is the point and m is the slope

Equation of the line using point P(3 , 5) and m = 2/3 is

$y - 5 = \frac{2}{3} (x - 3)$

$y - 5 = \frac{2}{3} x - 2$

$y = \frac{2}{3} x + 5 - 2$

We have the final answer as

$y = \frac{2}{3} x + 3$

Hope this helps you
