Answer:
-9
Step-by-step explanation:
Slope is the same so y=-2x+b
Plug in x and y
-3=-2(-3)+b
-3=6+b
b=-9
(Y-intercept is -9)
Answer:area of big square is 9x6 = 54 sq ft. Area of smaller square is 6x4 = 24 square feet. So if you throw a dart, you have a 24/54 or 4/9 chance of hitting the shaded spot.
Step-by-step explanation:
So for this trinomial, I will be factoring by grouping. Firstly, what two terms have a product of 16x^2 and a sum of 10x? That would be 8x and 2x. Replace 10x with 2x + 8x:
Next, factor x^2 + 2x and 8x + 16 separately. Make sure that they have the same quantity inside the parentheses: 
<u>Now you can rewrite this as 
, which is your final answer.</u>
Answer:
6 gallons
Step-by-step explanation:
You can find this using the ration method.
If, 8 gallons : 192 miles
x gallons : 144 miles
We must find the value of x, which is the number of gallons used to travel 144 miles.
Cross multiply the ratios.
192 x = 8 × 144
192 x = 1152
x = 1152 ÷ 192
x = 6
∴ It takes 6 gallons to travel 144 miles.
