Answer:
What they mean is if you substitute the value given for x into the equation given, is the math statement true.
Step-by-step explanation:
1) Is x = -3 a solution to 6x + 4 = -12?
6(-3) + 4 = -18 + 4 = - 14, so no, for number 1, x = -3 is not a solution to 6x + 4 = -12
Make sense?
LMK if you need me to run the rest of them with you.
Answer:
y-intercept: (0,-4)
x-intercept: (-16,0)
Step-by-step explanation:
To solve for X, Substitute 0 for Y and continue.
To solve for Y, Substitute 0 for X and continue.
Answer:
20x^2+23x+6
Step-by-step explanation:
(4x+3)(5x+2)
(4x)(5x)+2(4x)+(5x)3+3(2)
20x^2+8x+15x+6
20x^2+23x+6
Hope that helps :)
Answer:
1/45 ≈ 0.022
Step-by-step explanation:
There are originally 10 juice boxes in the cooler, 2 of which are grape.
The probability that the first juice box is grape is 2/10.
The probability that the second juice box is grape is 1/9.
The probability of both is (2/10) (1/9) = 1/45 ≈ 0.022.
Answer:
Step-by-step explanation:
Given the equation y = 2,5x
y is the height of the water
x is the time.
To get the range of values of the height at t = 60s, we will substitute x = 60 into the function
y = 2.5(60)
y = 150 in
Hence the range of the situation is [0, 150].
The domain will be all positive integers i.e xEZ
