Answer:
Step-by-step explanation:
So first, lets solve for the intercepts.
Let’s start by finding the x intercept.
Plug in 0 for y.
10x+9(0)=-90
10x=-90
X=-9, so your first point on your line will be (-9,0).
Now the y intercept.
Plug in 0 for x.
10(0)+9y=-90
9y=-90
Y=-10, so your second point on your line will be (0,-10).
Use those points to create your line.
Answer:
-11
Step-by-step explanation:
3x+10=2x-1
3x-2x+10=-1
x+10=-1
x=-1-10
x=-11
Answer:
120 miles
Step-by-step explanation:
Let d represent the number of miles driven on the first day. Then 1.5 times d came to 180 miles. Dividing both sides of this equation by 1.5 to isolate d, we get:
180 miles
--------------- = 120 miles
1.5
Thefamily drove 120 miles during the first day of their trip.
Answer:
i cannot help you get the answer to the question without more information but i can explain how to solve it, what your question is, is called a "permutation"
Step-by-step explanation:
To calculate permutations, use the equation nPr, where n is the total number of choices and r is the amount of items being selected. To solve this equation, use the equation nPr = n! / (n - r)! , an exclimation point means the factorial, say we need the factorial of 4, we would do this 4x3x2x1 go left to right, and it is not all at once. you multiply 4 times 3 which equals 12, then multiply 12 times 2... so on and so forth
