If I am correct it will equal 23.
Explanation: x2 + 4x +2 =7, x2 +x+3 =23
Answer:
f(4) = 3
When f(x) = 4, x = -1
Step-by-step explanation:
f(4) states that x co ordinate= 4. We need to find the y -co ordinate when x =4;
From the graph, when x = 4 , f(4) = 3
When f(x) = 4 , the x - co ordinate is -1
It would be .2 not 2 because the smaller number is first
2 divided by 10 is .2
Answer:
A
Step-by-step explanation:
Given the 2 equations
2x + y = 13 → (1)
x - y = - 4 → (2)
Add the 2 equations term by term to eliminate the y- term, that is
3x = 9 ( divide both sides by 3 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
2(3) + y = 13
6 + y = 13 ( subtract 6 from both sides )
y = 7
solution is (3, 7 ) → A
The answer is 3/4.
25% of the 200 jelly beans are green, by converting 25% into a decimal and multiplying it by the total amount of jelly beans, you can find the amount of jelly beans that are green.
25% = 0.25
200 x 0.25 = 50
Therefore 50 of the jelly beans are green.
The question wants to know the probability of the jelly bean being picked is not green.
200 - 50 = 150 jelly beans not green
Finding the probability:
150/200 = 3/4
