<span>Hello : let  A(-3,7)    B(3,3)
the slope is :   (YB - YA)/(XB -XA)
(3-7)/(3+3)  = -2/3
an equation is : y=ax+b     a is a slope</span>

y = (-2/3)x +b

 

the line through point B (3,3) :  3 = (-2/3)(3)+b<span>
<span>b =5 
the equation is : y =(-2/3)x+5</span></span>

Solve for x. Round to the nearest hundredth.
Airida [17]

Answer: 32.98^{\circ}

Step-by-step explanation:

Since, By the given diagram,

In quadrilateral ABCD, all angles are right angles ⇒ DC = AB = 15 cm and CB = DA

Also, In triangle DFA,

sin 56^{\circ} = \frac{DA}{DF}

⇒ sin 56^{\circ} = \frac{DA}{16}

⇒ 16\times sin 56^{\circ}=DA

⇒ 13.2646011609\text{ cm} = DA

Now, In triangle, DEC,

tan x = \frac{EC}{DC}

⇒ tan x = \frac{EB-CB}{DC}

⇒ tan x = \frac{EB-DA}{DC}

⇒ tan x = \frac{23-13.2646011609}{15}  

⇒ tanx = \frac{9.73539883912}{15}

⇒ tanx = 0.64902658927

⇒ x = 32.9846428556^{\circ} \approx 32.98^{\circ}

Explain how you can solve 8x45 using the distributive property
Lana71 [14]

The area of the triangle is 28.7 square centimeters. What is the base length of the triangle in centimeters?
Montano1993 [528]

In order to derive the base of a triangle from its area, you need its height as well.

In fact, if we solve the area formula for the base, we have

A=\dfrac{bh}{2} \iff 2A = bh \iff b=\dfrac{2a}{h}

So, the base length would be

b=\dfrac{2\cdot 28.7}{h} = \dfrac{57.4}{h}

where h is the height relative to the base you're interested in.

bekas [8.4K]

Answer:

y=1/3 + 3

Step-by-step explanation:

y= 1/3x + b

(1) = 1/3(-6) + b

1 = -2 +b

3 = b

y=1/3 + b
