Awesome!!! so his tools and stuff cost $80 and 6.25 PER BIRD HOUSE.
To make a profit he needs to make more that 80 and 6.25+. And he'll sell the bird houses for $16.
So we'll multiply. 16x (blank)=. And make it more than 80.
Step 2.
Let's say that you've got 5 bird houses. Now you have to mutliply 6. 25 and 5 because Juan had to pay that extra 6.25 per bird house.
Hi there!
23x - 4 = -2
23x = 2
x = 2/23
Hope this helps!
Answer:
Step-by-step explanation:
O
3x² - 11x - 4 = 0
a = 3 ; b = -11 , c = -4
W
8x² + 12x = -1
8x² + 12x + 1 = 0
a = 8 ; b = 12 ; c = 1
L
x² + x = 6
x² + x - 6 = 0
a = 1 ; b= 1 ; c = -6
G
x²- 2x - 2 =0
a = 1 ; b = -2 ; c = -2
E
4x - 5 = -4x²
4x² + 4x - 5 = 0
a = 4 ; b = 4 ; c = -5
B
12x² +x -6 = 0
a = 12 ; b = 1 ; c = -6
R
2x² + 5x - 25 = 0
a = 2 ; b = 5 ; c = -25
A
6x² -5x - 4 = 0
a = 6 ; b = -5 ; c = -4

Answer:
The equation of this line is therefore y = 2x + 3.
Step-by-step explanation:
this line passes thru the points (0, 3) and (3, 9). As we move from (0, 3) to (3, 9), x increases by 3 and y increases by 6. Thus, the slope of this line is
m = rise / run = 6/3, or m = 2. Inserting the known info (m = 2, x = 0, y = 3) into y = mx + b, we get: 3 = 2(0) + b, so we see that b = 3.
The equation of this line is therefore y = 2x + 3.
