For answer A, since the constant 5+. The line would go [ 3, 8, 13, 18, 23, 28, 33, 38, ] and so on.
Answer:
Each bouquet included 2 foil balloons and 8 latex balloons.
Step-by-step explanation:
Let f represent the number of foil balloons in each bouquet. Then 10-f is the number of latex balloons. The problem statement tells us the cost of all of the bouquets is ...
18(1.94f +0.17(10-f)) = 94.32
We can divide by 18 to get ...
1.94f +1.70 -0.17f = 5.24
1.77f = 3.54 . . . . . . . . . . . . subtract 1.70
f = 3.54/1.77 = 2 . . . . . . . . divide by the coefficient of f
The number of latex balloons is 10-2 = 8.
Each bouquet included 2 foil and 8 latex balloons.
Answer:
D
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
If m > 0 , then line slopes upwards from left to right
If m < 0 , then line slopes downwards from left to right
y = 3x - 2
has m > 0 and c = - 2 , thus line slopes upwards crossing the y- axis at - 2
y = - 2x + 3
has m < 0 and c = 3, thus line slopes downwards crossing the y- axis at 3
on the graph this is the lower blue line and the red line
the solution to the system is at the point of intersection of the 2 lines
This is at point D
The answer is 1/3 because I just took the test
Answer:
0
Step-by-step explanation:
Make and equation and solve for x.
(2x+10)^2 = 4(x-5)^2 Now the easiest thing to do is use the formula for squared binomial, (a+b)^2 = a^2 + 2ab + b^2.
4x^2 + 40x + 100 = 4(x^2 - 10x + 25)
4x^2 + 40x + 100 = 4x^2 - 40x + 100
From hear you can cancel out similar terms
40x + 100 = - 40x + 100
40x = -40x
add 40x to both sides
80x = 0
x = 0
The only solution to this is 0.
