Explain why the intercepts, on their own, cannot be used to graph the relation 5x+9y= 0.
goldfiish [28.3K]
5x + 9y = 0

to find the x int, sub in 0 for y and solve for x
5x + 9(0) = 0
5x = 0
x = 0

to find the y int, sub in 0 for x and solve for y
5(0) + 9y = 0
9y = 0
y = 0

the reason u cannot use just the intercepts is because the line goes through the origin (0,0)....The intercepts coincide giving u only 1 point...and that is not enough to graph a line

The proof ABC ≅ DCB that is shown.
Schach [20]

The <em><u>correct answer</u></em> is:

AAS

Explanation:

AAS stands for "angle-angle-side."  This states that if two angles and a non-included side of one triangle are congruent to the corresponding two angles and non-included side of another triangle, then the triangles are congruent.

In these triangles, we have ∠CAB ≅ ∠CDB given to us to begin with.  Throughout the proof, we find that ∠ABC ≅ ∠DCB.  We also have that CB is congruent to itself.  This is two angles and a side not included, so this is AAS.

20 how much metal is needed to smelt a cubical metal box with outer side 12 inches long if the thickness of its walls should be
guajiro [1.7K]
The volume of the metal box if the box was completely solid (V1), is:
 
 V1=(12 inches)³
 V1=1728 inches³
 
 As there are 3 inches of metal on both sides, the widht if the metal box was not completely solid, is:
 
 W=12 inches-(3 inchesx2)
 W=6 inches
 
 Then, the volumen of the no solid metal box is:
 
 V2=(6 inches)³
 V2= 216 inches³
 
 Therefore, the volume of metal needed to smelt the cubical metal box, is:
 
 V3=V1-V2
 V3=1728 inches³-216 inches³
 V3=1512 inches³

A line passes through the point (10,9) and has a slope of 3/2. Write an equation in slope intercept form for this line
Andre45 [30]

Answer:

The equation of line passing through (10,9) and having slope 3/2 is: y = \frac{3}{2}x-6

Step-by-step explanation:

The slope intercept form of a line is given by:

y=mx+b

We are given

Slope = m = 3/2

Point = (10,9)

Putting the value of the slope in the equation we get

y = \frac{3}{2}x+b

b is the y-intercept. To find the y-intercept we have to put the point through which the line passes in the equation.

Putting (10,9) in the equation

9 = \frac{3}{2}(10) +b\\9 = 15+b\\b = 9-15\\b = -6

Putting b=-6 in the equation

y = \frac{3}{2}x-6

Hence,

The equation of line passing through (10,9) and having slope 3/2 is: y = \frac{3}{2}x-6
