Answer:
Part A
it supposed to be x⩾-1/3 since you divided by negative
Step-by-step explanation:
Part A
4-6x⩾-15x+1
step 1: add -6x to both sides
4-6x+6x⩾-15x+6x+1
=4⩾-9x+1
step 2: subtract 1 from both sides
4-1⩾-9x+1-1
3⩾-9x
step 3: do reflexive property and divide
3⩾-9x
= <u>-9x⩽3</u>
-9
x⩽-1/3
and since you divided by negative, the sign must change. so it'll be x⩾-1/3
The answer is B. <span>{(1, 2), (2,4), (−1, 2), (0,3)} because it's the only answer where the variables for x aren't repeated. For example, x is 3 twice in A, x is 5 twice in C, and x is -4 twice in D. Please mark me Brainliest! :)</span>
One solution x = 1, y = 4
SInce there are six teams and each pair of shoes for each individual player is $630, set up this equation:
630 (total thus far) = 6x (six times the cost of last year)
630/6 = x
This means that last year's cost was $105.
If function f(x) = 3x² + 5 then the value of f(x + 3) - [f(x) + 3] is 18x + 24.
Given the function f(x) = 3x² + 5.
We have to find the value of f(x + 3) - [f(x) + 3]
First we have to find the value of f(x + 3) - [f(x) + 3]
f(x + 3) = 3 (x + 3) ² + 5f(x + 3)
= 3(x ² + 6x + 9) + 5f(x + 3)
= 3x ² + 18x + 27 + 5f(x + 3)
= 3x ² + 18x + 32
Now substitute these values and find the value of f(x + 3) - [f(x) + 3].
f(x + 3) - [f(x) + 3] = (3x² + 18x + 32) - [3x ^ 2 + 5 + 3]
=3x ² + 18x + 32 - 3x ² - 8
=18x + 24
