The y intercept of the graph 0.25x+0.05y=1.00

makvit [3.9K]

Hello!!

Well, the y-intercept is found when x = 0, so plug in x = 0:

0.25(0) + 0.05y = 1
0.05y = 1
y = 20

Therefore, the y-intercept of 0.25 + 0.05y = 1.00 is 20.

Hope this helps!! Let me know if you have ANY questions.

Fill in the blanks to make an arithmetic sequence

Arlecino [84]

-----------------------------------------
General Equation:
-----------------------------------------
$T_n = a_1 + d(n - 1)$

-----------------------------------------
Find d :
-----------------------------------------
$a_1 = 11, T_7 = 79,$
$T_7 = 11 + d(7 - 1)$
$-79 = 11 + 6d$
$6d = -79 - 11$
$6d = -90$
$d = -15$

-----------------------------------------
Find general equation :
-----------------------------------------
$T_n = 11 + (-15)(n - 1)$
$T_n = 11 -15n + 15$
$T_n = 26 -15n$

-----------------------------------------
Find the sequence :
-----------------------------------------
$T_1 = 26 - 15(1) = 11$
$T_2 = 26 - 15(2) = -4$
$T_3 = 26 - 15(3) = -19$
$T_4 = 26 - 15(4) = -34$
$T_5 = 26 - 15(5) = -49$
$T_6 = 26 - 15(6) = -64$
$T_7 = 26 - 15(7) = -79$

---------------------------------------------------------
Answer: 11, -4, -19, -34, -49, -64, -79
---------------------------------------------------------

Simplify 3a + 2b - 8a + b

Harlamova29_29 [7]

To simplify 3a + 2b - 8a + b, we need to combine like terms. Like terms are terms that share common variables. In this expression, the two variables are terms with a and terms with b. The terms that have a are 3a and -8a. The terms that have b are 2b and b. Now we can separate them and simplify.

(3a - 8a) + (2b + b)

-5a + 3b
