A line l with slope −45 passes through the point (-10, 4). Is the point (-5, 8) on line l?

Anvisha [2.4K]

Answer: 8.1

Step-by-step explanation: How you convert a mixed number into a decimal is taking the whole number (not the fraction part) and putting it in front of the decimal, then you get the fraction's denominator to 10 multiply if needed, then you take the fractions top number and put it after the decimal, Now your converted!

If you need any further help or instruction let me know!

Find the points of intersection of the graphs of the equations.

AURORKA [14]

Answer:

To find the point of intersection, just solve for x and y in the equations

so since x - y = -5

x = y - 5

now that we have a value of x, we will substitute x with in in the other equation

5x + 3y = -9

5(y-5) + 3y = -9

5y - 25 + 3y = -9

8y = 16

y = 2

now use this value of y in the equation we made for x

x = y - 5

x = 2 - 5

x = -3

Hence, the point of contact is (-3 , 2)

80*t+70*t=50
t = .33 hours =20 minutes
This assumes the trains are going opposite directions (opposite tracks so I’m assuming opposite directions)

Which function below has the lowest y intercept? f(x) graph going through (0, 5) and (2, 1) g(x) Kyle started the summer having

mr Goodwill [35]

First find the slope of f(x).

m=(y2-y1)/(x2-x1)

m=(1-5)/(2-0)

m=-4/2

m=-2

y=-2x+b, using (2,1) we can solve for the y-intercept, "b"

1=-2(2)+b

1=-4+b

5=b

y=-2x+5

So f(x) has a y-intercept of 5

g(x)=6m+3

So g(x) has a y-intercept of 3

h(x)=3x+4

So h(x) has a y-intercept of 4

Then g(x) has the lowest y-intercept of just 3.

Answer:

7/22

Step-by-step explanation:

Step 1: Define/explain.

To subtract fractions with different denominators, you must first find the least common denominator (LCM).

You can do this by listing the multiples of each denominator.

Step 2: Solve.
