Answer:
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u>
- The slope of the line in the graph is 4.
And we need to find the equation of the line. On looking at the graph we see that , it cuts y axis at (0,3) .So the y Intercept of the equation is 3 .
<u>Slope</u><u> Intercept</u><u> Form</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Substituting</u><u> the</u><u> respective</u><u> values</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence</u><u> the</u><u> </u><u>equation</u><u> of</u><u> </u><u>line </u><u>is </u><u>y </u><u>=</u><u> </u><u>4</u><u>x</u><u> </u><u>+</u><u> </u><u>3 </u>
Answer with Step-by-step explanation:
f(1) = 160 and f(n + 1) = –2f(n)
⇒ f(2)= -2×f(1)
= -2×160
= -320
⇒ f(3)= -2×f(2)
= -2×(-320)
= 640
⇒ f(4)= -2×f(3)
= -2×640
= -1280
Hence, Value of f(4) is:
- 1280
Answer:
-.8
Step-by-step explanation:
divide both sides by 2.8
3d-2=-4.4
add two to both sides
3d=-2.4
divide both sides by 3
d=-.8
Answer:
7
Step-by-step explanation:
x + 3 : x + 8 : : 2 : 3
(x + 3) \times 3 = (x + 8) \times 2 \\ 3x + 9 = 2x + 16 \\ 3x - 2x = 16 - 9 \\ x = 7 \\ x + 3 = 7 + 3 = 10 \\ x + 8 = 7 + 8 = 15 \\
10 : 15
2 : 3
