Answer:

345

Step-by-step explanation:

7-\left(-19\right)-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187

7+19-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187

26-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187

8+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187

8-19+187-\left(-19\right)-18+\left(-19\right)+187

-11+187-\left(-19\right)-18+\left(-19\right)+187

176-\left(-19\right)-18+\left(-19\right)+187

195-18+\left(-19\right)+187

177+\left(-19\right)+187

177-19+187

158+187

The vertex of the graph of y = -4(x + 3)2 + 2 is <br><br> (____,____)
Mars2501 [29]

Answer: The vertex is (-3, 2)

The equation y = -4(x + 3)^2 + 2 can be written as y = -4(x - (-3))^2 + 2

I rewrote x+3 as x - (-3)

Compare y = -4(x - (-3))^2 + 2 with the general template y = a(x-h)^2 + k

Note how

a = -4

h = -3

k = 2

So the vertex is (h,k) = (-3, 2)

Determine the type of boundary line and shading for the graph of the inequality 3x + y greater than or equal to 10.
horrorfan [7]

Answer: second option

Step-by-step explanation:

The equation of the line in slope-intercept form is:

y=mx+b

Where m is the slope and b is the y-intercept.

Rewrite the expression as:

3x+y=10

Solve for "y":

y=-3x+10

You can identify that:

m=-3\\b=10

Therefore, the line intersects the y-axis at the point (0,10)

For the graphs of inequalities with \geq\ and\ \leq the line must be solid.

The inequality given is 3x+y\geq 10 and it can be written as y\geq -3x+10

Then, the shaded region must be above the solid line. Therefore  it does not include the origin (Observe the graph attached).

Strangely, she lifted us up like a feather on a breeze.
son4ous [18]
The answer is C

This is because “like a” is a simile and “feather on a breeze” is personification

Hope this helped!

loris [4]
<span>Brian and shadow to Z point math hypotenuse of a right triangle . Tree and shadow to the right-angled triangle hypotenuse well . Shadow length depends on the angle of incidence of solar prmieni . The angle of Padania , in both cases the same joke . So tangents hypotenuse same joke .

tg = a/b
Brian
a/b = 6ft/4ft = 1,5

A tree
a/b = a/20ft

a/20ff = 3/2    </span><span>We multiply the cross

2a = 60ft
a = 30tf

Answer : </span>The tree is 30 feet
