Which of these are the intercepts of the graph of y = 3x – 12?

2 answers:

7 0

Hello there! :) To find one intercept, you'll need to set the other one to 0. For instance: x intercept: y=0 y intercept: x=0 X Intercept: 0= 3x-12 Add 12 to both sides to isolate x. 0+12= 3x-12+12 12= 3x Divide both sides by 3. 12/3=3x/3 4= x intercept Y Intercept: You could plug in x as 0 and solve, but a quick way to find it in a slope-intercept equation is to look at the number at the end (without the x.) In this problem it would be -12. Hope this helps! :) Let me know if you need any additional helps.

Y intercept is (0,-12), the x-intercept is (4,0)

Answer: 168cm^2

Step-by-step explanation:

lets split this into two shapes:

a rectangle and a triangle

Formulas:

rect: b * h

Tri: (b*h)/2

Solve:

12 * 10 = 120

(12*8)/2 = 48

120 + 48 =

If a salesperson sells 3/4 of an acre for $80,000, what was the price per square foot rounded to two decimal spaces?

Julli [10]

Now, recalling that for 1 yard, there are 3 feet, therefore $\bf \begin{array}{ll}
yards&feet\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1yd&3ft\\
(1yd)^2&(3ft)^2\\
yd^2&3^2ft^2\\
&9ft^2
\end{array}$

and keeping in mind that, there are 4840 yd² in 1 acre, then

$\bf \cfrac{\quad \frac{3}{4}~\underline{acre}\quad }{80000~\$}\cdot \cfrac{4840~\underline{yd^2}}{\underline{acre}}\cdot \cfrac{9~ft^2}{\underline{yd^2}}\implies \cfrac{\frac{3}{4}\cdot4840\cdot 9~ft^2}{80000~\$}\implies \cfrac{\frac{130680}{4}}{80000}
\\\\\\
\cfrac{\frac{130680}{4}}{\frac{80000}{1}}\implies \cfrac{130680}{4}\cdot \cfrac{1}{80000}\implies \cfrac{3267}{8000}~\frac{ft^2}{\$}~\approx~ 0.408375 ~\frac{ft^2}{\$}$

The length of the sides DEF are 12,16,and 20. Find the perimeter of the triangle formed by connection the midpoints of the sides

Mekhanik [1.2K]

Answer:

24 units

Step-by-step explanation:

According to the midsegment theorem, the length of each side of the formed triangle is the half the parallel side of DEF.

<u>So the perimeter is:</u>

P = 1/2(12 + 16 + 20) = 24
