Mathematics

Answer:

m=2

Step-by-step explanation:

When you put a number into the inverse of a function (f^-1) you get the original number back.

Ex: f^-1(11) = (11-3)/2 = 4

f(4) = 2×4+3 = 11

So, f(-5)=-2

So, when x is -5,

f(x) = -2

f(x)=m(-5)+8

-2=m(-5) + 8

m=2

Can someone please help me with this
natta225 [31]

Answer:

(a)\ (1,5)

Step-by-step explanation:

Given

(x + 9)^2 + (y - 4)^2 = 101

Required

Which of the points does it pass through

To do this, we simply substitute the values of x and y in the above equation.

So, we have:

(a)\ (1,5)

(x + 9)^2 + (y - 4)^2 = 101

(1 + 9)^2 + (5 - 4)^2 = 101

Solve each bracket

10^2 + 1^2 = 101

100 + 1 = 101

101 = 101

The above equation is true,

<em>Hence, it passed through </em>(1,5)

<em>We do not need to check for others</em>

Not a test just that. ? Is throwing me off after 25x what does that mean genuinely confused
Andrej [43]

Answer:

For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is not necessary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x - 1).

Step-by-step explanation:

h=16t^2+126t

Let t=4

h = 16 (4)^2 +126(4)

h = 16*16 +126(4)
