Evaluate please<br> 2x+(−6)∙(y+1) for x=−1.5 and y=−3

Andreyy89

First, you plug your given values in. Since x is 1.5, it will be multiples by 2x to get 3.2. Since y is -3, it will be added to 1 to get -2. Finally, the two are multiplied together to get -6.4 if I am correct.

Look at the rectangle and the square

Komok [63]

Answer:

NO. Ada is not correct.

Step-by-step explanation:

Using Pythagorean Theorem, find the length of the diagonal of the rectangle and the square, respectively.

✔️Diagonal of the Rectangle:

$a^2 + b^2 = c^2$

Where,

a = 8 in.

b = 16 in.

c = hypotenuse (longest side of a right ∆)

Plug in the values into the equation

$8^2 + 16^2 = c^2$

$64 + 256 = c^2$

$320 = c^2$

Take the square root of both sides

$\sqrt{320} = \sqrt{c^2}$

$17.9 = c^2$ (nearest tenth)

Length of diagonal SQ = 17.9 in

✔️Diagonal of the Rectangle:

$a^2 + b^2 = c^2$

Where,

a = 8 in.

b = 8 in.

c = hypotenuse (longest side of a right ∆)

Plug in the values into the equation

$8^2 + 8^2 = c^2$

$64 + 64 = c^2$

$128 = c^2$

Take the square root of both sides

$\sqrt{128} = \sqrt{c^2}$

$11.3 = c^2$ (nearest tenth)

Length of diagonal OM = 11.3 in.

SQ is not two times the length of OM.

Therefore, Ada is not correct.

I need help with this question please

tatuchka [14]

Answer:

y=1/2x+4

Step-by-step explanation:

To find the formula of a line with slope intercept form, you need to know the slope of the line and the y intercept (where the line crosses the y axis, or where x is 0). The y intercept is visibly at (0,4). To find the slope of the line, you need to find how much the line "rises" in a certain amount of "run". You can see that the line moves two to the right for every one unit it moves up, meaning that it has a slope of 1/2. Plugging this into the slope intercept form, or y=mx+b, where m is the slope and b is the y intercept, you get:

y=1/2x+4

Hope this helps!
