Answer:
425 min$80Step-by-step explanation:
The equation to reflect the monthly plans:
Plan A f(x) = 0.16x + 12Plan B g(x) = 0.12x + 29We need to find the value of x when f(x) = g(x):
0.16x + 12 = 0.12x + 290.16x - 0.12x = 29 - 120.04x = 17x = 17/0.04x = 425 minutesThe cost is:
$0.16*425 + $12 = $80If we put on equations
y=0.16x+12y=0.12x+29Amount of calling is x and cost is y
solve
0.16x+12=0.12x+290.04x=17x=17/0.04x=425minCost
0.12(425)+29=$80What is an equation of the line that passses through the points (-8,-6) and (3,-6)
Answer:
y = -6
Step-by-step explanation:
Notice the y coordinate of both points is -6
Therefor the line is horizontal
y = -6
Step-by-step explanation:
[tex]gradient = \frac{( - 6 - ( - 6))}{(3 - ( - 8))} \\ = \frac{0}{11} \\ = 0 \\ from \: \: y = mx + c \\ at \: (3, \: - 6) \\ - 6 = (0 \times 3) + c \\ c = - 6 \\ y = mx + c \\ y = - 6[/tex]

solve this parallelogram angle
Answer:
103
Step-by-step explanation:
angles formed on the same line of a parallelogram are supplementary angles
( the angle with the measure of 77 degrees and the angle labeled "x" are formed on the same line which means they are supplementary )
supplementary angles add up to equal 180
hence, 77 + x = 180
180 - 77 = 103
Hence, x = 103
Answer:
103°
Step-by-step explanation:
Hint :sum of angles of quadrilateral = 180°Simplify:77° + x° = 180°
x° = 180° - 77°
x° = 103

in circle k secant pec intersects chord bkd at f if ae is congruent to ab the measure of arc ed is 32 and arc bc: arc cd is 2:1 then find the measure of angle p
Answer:
60°
Step-by-step explanation:
Diameter of circle = BD ; Hence, BD = 180°
Arc BC : CD = 2 : 1
BD = BC + CD = 180
BC = 2/3 * 180 = 120°
CD = 1/3 * 180 = 60°
Since ED = 32°
BE = 180 - 32 = 148°
BA = AE
BE = BA + AE
BA = AE = 148° / 2 = 74°
Arc ABC = BA + BC
Arc ABC = 74° + 120 = 194°
P = (Arc ABC - AE) / 2
P =(194 - 74) / 2
P = 120 / 2
P = 60°
Inscribed angles math lib
Need help with 5, 6, 7, 8 thank you !!!
Answer:
5. B) x = 7
6. D) 35°
7. C) 67°
8. A) 142°
Step-by-step explanation:
5. Inscribed angle of a semicircle is equal to 90°. Therefore,
16x - 22 = 90
Solve for x
16x - 22 + 22 = 90 + 22
16x = 112
16x/16 = 112/16
x = 7
6. Recall: inscribed angle = ½(intercepted arc)
3x - 1 = ½(8x - 26)
2(3x - 1) = 8x - 26
6x - 2 = 8x - 26
Collect like terms
6x - 8x = 2 - 26
-2x = -24
-2x/-2 = -24/-2
x = 12
m<LMN = 3x - 1
Plug in the value of x
m<LMN = 3(12) - 1 = 36 - 1
m<LMN = 35°
7. Recall: inscribed angle = ½(intercepted arc)
Therefore,
4x + 28 = ½(11x - 1)
2(4x + 28) = 11x - 1
8x + 56 = 11x - 1
Collect like terms
8x - 11x = -56 - 1
-3x = -57
-3x/-3 = -57/-3
x = 19
Arc BC = 360° - (Arc AC + Arc AB) (Full circle)
Substitute
Arc BC = 360 - (11x - 1 + 85)
Plug in the value of x
Arc BC = 360 - (11*19 - 1 + 85)
Arc BC = 360 - (209 - 1 + 85)
Arc BC = 360 - 293
Arc BC = 67°
8. Inscribed angles intercepted by the same arc are equal. Therefore,
8x - 41 = 5x + 1
Collect like terms
8x - 5x = 41 + 1
3x = 42
3x/3 = 42/3
x = 14
5x + 1 = ½(arc PS) => inscribed angle = ½ of intercepted arc
2(5x + 1) = arc PS
Plug in the value of x
2(5*14 + 1) = arc PS
2(70 + 1) = arc PS
2(71) = Arc PS
Arc PS = 142°
(x + 3) - [(x+ 2)(x2 - 1)]

For what intervals of x is f(x) increasing
Answer:
The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.
