Answer:
(−2, −8)
Step-by-step explanation:
Write the problem as a mathematical expression.
y = 7x + 6
4x − 3y = 16
Replace all occurrences of y in 4x − 3y = 16 with 7x + 6. 4x − 3 (7x + 6) = 16
y = 7x + 6
Simplify 4x − 3 (7x + 6).
−17x − 18 = 16
y = 7x + 6
Solve for x in the first equation.
Move all terms not containing x to the right side of the equation.
−17x = 34
y = 7x + 6
Divide each term by −17 and simplify.
x = −2
y = 7x + 6
Replace all occurrences of x with −2 in each equation.
Replace all occurrences of x in y = 7x + 6 with −2. y = 7 (−2) + 6
x = −2
Simplify 7 (−2) + 6.
y = −8
x = −2
The solution to the system is the complete set of ordered pairs that are valid solutions.
(−2, −8)
The result can be shown in multiple forms.
Point Form:
(−2, −8)
Equation Form:
x = −2, y = −8
Answer:
(b) 5.04 < 5.4
Step-by-step explanation:
The pointed end of the < symbol points to the smaller (lesser) number or expression. Here, the number 5.04 is less than 5.4, so the appropriate choice is ...
5.04 < 5.4
The ordered pair that is the solution to these equations is (-2,-1)
work:
2(-2)+5(-1)=-9
3(-2)-4(-1)=-2
Answer:
a×10⁰ where (a the number) should always be less than 10
hope it helps :)
The researchers could utilize a probability sample.
Meaning of a Probability Sample
Every member of a population must have an equal chance of being chosen for a study in order for a sample to be considered a probability sample, and the researcher must be aware of this likelihood. The most typical type of sampling used in public opinion research, election polling, and other studies whose findings will be generalized to a larger population is probability sampling in which probability samples are made use of.
Probability Sample as the Representative of Population Sample
Here, a sample that qualifies for a representative of the population the researchers are studying, must consist of members having equal chances to be chosen for the study. Thus, a probability sample is the best representative of their study population.
