Answer:
Option (a)
Step-by-step explanation:
The given equation is
y = 4 (2ˣ)
To find y-intercept, substitute x=0 in the equation.
y = 4 (2⁰) = 4 (1) =4
Hence y-intercept is 4.
Since y-intercept is 4, the equation should pass through the point (0,4).
The only graph passing through the point (0,4) is the graph in option (a).
Hence the answer is option (a).
Answer:
i think it is 140
Step-by-step explanation:
i think i did that question before
There are 13 diamonds, and 4*3=12 face cards, of which 3 are diamonds.
So total of "diamond or face card" is 13+12-3=22.
=>
Probability of drawing a diamond OR a face card from a full 52-card deck is
22/52=11/26.
Answer:
<h2>D. They will be negative numbers.</h2>
Step-by-step explanation:
If the inequality models scores of 20 and 30 points, then the values for variables x and y must be positive, because you can't score a negative number, you score or you don't that's it.
Therefore, the right answer is D. They will be negative numbers, because score can't be negative numbers.
The solution is: x= 7 and y = 2
Step-by-step explanation:
Given equations are:
Putting x = 3y+1 in equation 2 from equation 1
Subtracting 1 from both sides
Dividing both sides by 7
Putting y=2 in equation 1
Hence,
The solution is: x= 7 and y = 2
