Answer:
i dont know good luck
Step-by-step explanation:
how do you know how many solutions are possible for a system of equations
Answer:
Step-by-step explanation:
If the slopes are the same but the y-intercepts are different, the system has no solution.
If the slopes are different, the system has one solution.
If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
Answer:
Step-by-step explanation:
If you mean linear systems. If lines have a different slope there will be one solution. If they have the same slope (parallel) and a different y intercept there are zero solutions. If they have same slope and y intercept than they are the same line and have an infinite number of solutions.
what is 5/6 divided by 7/10
Select all the correct answers. Exponential function f is represented by the table. x 0 1 2 3 4 f(x) -12 -4 0 2 3 Function g is represented by the equation. g(x)=-12(1/3)^x Which statements are true about the two functions? Both functions are increasing on all intervals of x. The functions have the same y-intercept. Both functions approach the same value as x approaches ∞. Both functions approach -∞ as x approaches -∞. The functions have the same x-intercept.
Answer:
Both functions are increasing on all intervals of x: True
Both functions have the same y intercept: True
Both functions approach the same value as x approaches infinity: True
Both functions approach negative infinity as x approaches negative infinity: True.
The functions have the same x intercept: False, they have no x intercept.
Step-by-step explanation:
f(x) is stated to be an exponetial function, hence
[tex]f(x)=ab^{x}[/tex]
f(0) is given as -12, so
-12=a
f(1) is given as -4, so
-4=-12b
b=1/3
This implies that
[tex]f(x)=-12(\frac{1}{3})^{x}[/tex]
g(x) is stated to be
[tex]g(x)=-12(\frac{1}{3})^{x}[/tex]
Conclusion: the functions are identical.
Answer:
so the answers are
the functions have the same y-intercept
both functions approach negative infinity as x approaches infinity
both functions are increasing on all intervals of x

What is one method to find the measure of angle B?
A. use the Pythagorean theorem to find BC, then solve the equation tan(B)=8/BC
B. because of the 30-60-90 triangle theorem, you know the measure of angle B is 60
C. solve the equation cos(B)=8/89(square rooted)
The answer is A
Answer:
A
Step-by-step explanation:
edg2021
One method to find angle B is A. use the Pythagorean theorem to find BC, then solve the equation tan(B)=8/BC.
What is Pythagoras Theorem?Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
Given is a right angled triangle ABC with the hypotenuse being AB and the legs AC is the base and BC is the height.
Given AC = 8 and AB = √89.
We need to find the measure for angle B.
Either we can find angle B using Sin B = Opposite side / hypotenuse
Sin B = 8 / √89
But this is not in the option.
So first find the length of BC using the Pythagoras Theorem.
(BC)² = (AB)² - (AC)²
= (√89)² - (8)²
= 25
BC = √25 = 5
We get the opposite side and adjacent side with respect to angle B.
Tan B = AC / BC = 8 / 5 = 1.6
B = 57.99° ≈ 58°
Hence the approximate measure of angle B is 58°.

9514 1404 393
Answer:
x = 3.6
Step-by-step explanation:
The angle bisector divides the segments proportionally. This means they satisfy ...
bottom segment / side segment = x/6 = (6-x)/4
Multiplying by 12 gives ...
2x = 3(6 -x)
2x = 18 -3x . . . . . eliminate parentheses
5x = 18 . . . . . . . . add 3x
x = 3.6 . . . . . . . . . divide by 5
_____
Alternate solution
I like to try to work these mentally. The total of side lengths is 10, so the total base length (6) is 6/10 = 0.6 times that. Then x will be 0.6 times the left side length: 0.6·6 = 3.6 = x.
Identify the correct table for the following equation: Y=3x + 7 ( look at the picture for answer choices )
Answer:
The first choice is the right answer.
Step-by-step explanation:
Y = 3x+7
First choice
y = 3(0) + 7 = 7
y = 3(1) + 7 = 10
y = 3(2) + 7 = 13
second choice
y = 3(7) + 7 = 28. output on table shows 0
third choice
y = 3(0) + 7 = 7
y = 3(1) + 7 = 10 doesn't work as y output in third choice says 8
fourth choice.
y = 3(7) + 7 = 28 output on table shows 0
