What is the solution of the system? Use the graph. y=x+5 y=-5x-1

olga55 [171]

Y = x + 5
y = -5x -1

so than you make y = y so x + 5 = -5x -1 result 6x = -6 so x = -6/6 so x = -1
and than you check it

y = - 1 +5 = 4
and
y = - 5 *(-1) -1 = 5 -1 = 4

so this mean that - 1 is the solution of the system sure

Evaluate (−25)(38)/(−34).

muminat

Multiply 25 and 38, the divide that by 34.
the negatives will cancel because there is 1 on the top and 1 on the bottom.
i got 27.9412

Lauren has an above-ground pool. To keep the pool's skimmer working well, the water level must be 4 inches from the top of the p

KIM [24]

Answer:

<em>1885.5 m^3 of water</em>

<em></em>

Step-by-step explanation:

I'll assume this is the complete question

<em>Lauren has an above-ground pool. To keep the pool's skimmer working well, the water level must be 4 inches from the top of the pool. When the pool is filled to this recommended level, approximately how many cubic feet of water will it contain? Use π = 3.14 </em>

<u><em>The pool forms</em></u><em> a cylinder with a radius of 12 feet and a height of 4.5 feet.</em>

<em></em>

height of pool = 4.5 ft

radius of pool $12^{2}$ = 12 ft

height of water is 4 inches below pool top

<em>12 inches make 1 ft</em>

4 inches = 4/12 ft = 0.33 ft

Therefore, height of water = 4.5 - 0.33 = 4.17 ft

<em>volume of the water in this section of the cylinder will be equal to the volume of the cylinder formed</em>

volume of cylinder formed by the water = volume of water = π $r^{2}$ h

volume = 3.14 x $12^{2}$ x 4.17 = <em>1885.5 m^3 of water</em>

In ABC, side BC is extended to point E. When connected to vertex A, segment EA is parallel to segment BD. In this construction,

Two triangles are said to be <u>congruent</u> if they have <em>similar</em> properties. Thus the required <u>options</u> to complete the <em>paragraph proof</em> are:

a. angle 1 is <u>congruent</u> to angle 2.

b. <em>alternate</em> angles are <u>congruent</u> if two parallel lines are cut by a <em>transversal</em>.

c. $\frac{AD}{CD}$ = $\frac{AB}{CB}$

The <em>similarity property</em> of two or more shapes implies that the <u>shapes</u> are congruent. Thus they have the <em>same</em> properties.

From the given <u>diagram</u> in the question, it can be deduced that

ΔABC ≅ ΔABE (<em>substitution</em> property of equality)

Given that EA is <u>parallel</u> to BD, then:

i. <2 ≅ <3 (<em>corresponding</em> angle property)

ii. <1 ≅ < 4 (<em>alternate</em> angle property)

Thus, the required options to complete the <em>paragraph proof</em> are:

Angle 1 is <em>congruent</em> to angle 2.
Alternate angles are <u>congruent</u> if two parallel lines are cut by a <em>transversal</em>.
$\frac{AD}{CD}$ = $\frac{AB}{CB}$
