Jade and Ali set the alarms on their phones to sound at 7.15 am.
Kitty [74]

Answer:

9:15 am

Step-by-step explanation:

Alarms sound at 7:15 am

Alarm frequencies are 40 min and 60 min

Since 40= 20*2 and 60= 20*3, the overlapping frequency is:

  • 20*2*3= 120 min = 2 hours

So next time both alarms sound at 7:15 am + 2 hours = 9:15 am

20 POINTS!! What would be the first step to solve this equation?
Anettt [7]

Answer:

C. Add 13 to both sides of the equation.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Add 13 to both sides of the equation:

m - 13 = 24

m - 13 (+13) = 24 (+13)

m = 24 + 13

m = 37

HELP HELP
Liono4ka [1.6K]

Answer:

Equation of the parabola: y = 3 - 7x^2

Step-by-step explanation:

The equation of the parabola with vertex (h,k) is y = a(x - h)^2 + k

Thus, the equation of this parabola is  y = ax^2+3

To find a, use the fact that the parabola passes through the point (1,−4):

-4 = a(1)^2 +3

Solving this equation, we get that a = −7.

Thus, the equation of the parabola is y = 3 − 7x^2.

Can someone help with this math question please
kherson [118]
Regarding question number 47, which is what I can read well ...
 Equation 4 (3x-2) ² = 36 It can be solved in the following way:
 -Apply distributive property
 4 (9x ²-12x +4) = 36
 -We order the terms and equalize to zero
 36x² -48x +16 -36 = 0
 36 x ² -48x -20 = 0
 The roots of this equation are
 (-48 +  √(48 ²-4 ×36 × -20)) / 2 ×36
 and
 (-48 -  √(48 ²-4 × 36 ×-20)) / 2 ×36
 Finally the solution is:
 option C
 x = -1 / 3
 x = 5/3
