Step-by-step explanation:

The y-intercept of your graph is (0, -3)

Putting 4) in standard form:

y = 6x - 3 the y-intercept is also (0, -3)

3 1/9 dived by 2 2/5

cluponka [151]

3 + 1/9 = 27/9 + 1/9 = 28/9

2 + 2/5 = 10/5 + 2/5 = 12/5

------------------------------------------

So:

[3+(1/9)]/[2+(2/5)]

=(28/9)/(12/5)

=(28/9)*(5/12)

=140/108 = 70/54 = 35/27

You are designing a large rectangular fish tank for your tropical fish. The length will be 1 yard 3 inches, the width will be 1.

aliina [53]

Answer:

A. 14040 cubic inches

B. 61 gallons

Step-by-step explanation:

The volume of a cuboid is given by the formula ...

V = LWH

One yard is 36 inches, so 1 yard 3 inches is 36 +3 = 39 inches.

One foot is 12 inches, so 1.5 ft = 1.5×12 = 18 inches.

The volume of the fish tank is ...

V = (39 in)(18 in)(20 in) = 14,040 in³

The volume is 14,040 cubic inches.

One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.

976 cups equals 61 gallons.

_____

<em>Additional comment</em>

One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.

What is the area of a triangle whose vertices are X(1, 1), Y(3, -1), and Z(4,4)?

shepuryov [24]

Answer:

Step-by-step explanation:

Note that in this diagram, point A represents point X, point B represents point Y, and point C represents point Z.

From the diagram, it appears as if $\overline{XZ} \perp \overline{XY}$ . To determine if this is the case, we can find the slopes of both segments.

$m_{\overline{XZ}}=\frac{4-1}{4-1}=1\\m_{\overline{XY}}=\frac{-1-1}{3-1}=-1$

Since these slopes are negative reciprocals, we know that they are perpendicular.

This means we can use the formula $A=\frac{1}{2}bh$ , where b is the base (XY) and h is the height (XZ).

Note these are interchangeable.

Using the distance formula,

$XY=\sqrt{(3-1)^{2}+(-1-1)^{2}}=2\sqrt{2}\\XZ=\sqrt{(4-1)^{2}+(4-1)^{2}}=3\sqrt{2}$

This means the area is $\frac{1}{2}(2\sqrt{2})(3\sqrt{2})=\boxed{6}$

Impossible question for me plz help

klio [65]

Answer:

The line x = 3 is simply a vertical line that passes through every single point where x is equal to 3.

One that is is parallel and passes through (-4, 7) will be in the same format, just with another number. The given point has an x-coordinate of -4, so the line is:

x = -4
