Answer:

yes

Step-by-step explanation:

Try it and see:

2(-1) +5(-3) = -2-15 = -17 . . . . . works in the first equation

-4(-1) +3(-3) = 4 -9 = -5 . . . . . . works in the second equation

Yes, the ordered pair (-1, -3) satisfies the equations.

Or, you can check the solution using a graphing calculator.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

Given

The function f(x) is $(x+3)^2 - 10$ .

The axis of symmetry of f(x) is left side by 3 units.

The axis of symmetry of g(x) is 5 units to the right of f(x).

Then the axis of symmetry of g(x) is 2 units right side from the origin.

Then the g(x) will be

$\rm g(x) = (x - 2)^2 + k$

Thus, the correct option is A.

Answer:

No mode

Median: 12

Step-by-step explanation:

there is no mode because there is no 2 or more numbers that are the same

the median is 12 because if you put the number in order: 5,8,9,12,18,22,25 then the middle number is 12

Three times a larger number is 30 more than 5 times a smaller number. The sum of the larger number and 5 times the smaller numbe

snow_tiger [21]

3y = 5x+30 , y+5x = 50

using elimination method ...

3y-5x=30
+ y+5x=50
——————
4y = 80
y= 20

so using one of the original equations..

20 + 5x = 50
5x = 30
x =6

x = 6
y = 20
