Answer:
4 miles per hour
Step-by-step explanation:
We can divide 45 minutes by 3 to get 15 minutes:
So that is 1 mile in 15 mins
Then we multiply both sides by 4 to get 60 mins:
4 miles in 60 mins
So his rate was 4 miles per hour
(6g) and (-h) are the 2 terms in the expression
Step-by-step explanation:
The line
Is in point Slope form. This means the Slope and the y intercept are visible in the equation 9f the form
Where m is the Slope of the line and b is the y coordinate of the y intercept.
To determine the y intercept, assume x = 0, then - 3x = 0, so y = 3 and x = 0 (0,3}
From that point you can find the next point by choosing a value for x in the given equation to find a corresponding y.
Substitute 1 for x and get 0 for y, (1,0)
Substitue 2 for x and get - 3 for y, (2,-3)
To answer the questions use the supplied coordinates in the original equation.
#1. (-1,6)
This is a true statement, so the line does pass through this point.
#2 (12,-33)
Again, the statement is true, so the line passes through the point.
#3 (2,9)
This is a false {untrue} statement, so the point does not sit on the line.
Answer:
B
Step-by-step explanation:
9 more means the number of cars but with 9 added on to it ( hope that makes sense). It would be A if it was 9 TIMES the amount of cars in a parking lot. Look carefully at the words they use.
Answer:
<em>Step 1: Distribute 1.2 to 6.3 and –7x </em>
<em>Step 2: Combine 3.5 and 7.56</em>
<em>Step 3: Subtract 11.06 from both sides</em>
Step-by-step explanation:
Given the expression 3.5 + 1.2(6.3 – 7x) = 9.38, we are to write the possible steps involved in solving the equation
3.5 + 1.2(6.3 – 7x)
Step 1: Distribute 1.2 to 6.3 and –7x
3.5 + 1.2(6.3 – 7x) = 9.38
3.5 + 1.2(6.3) + 1.2(-7x) = 9.38
3.5 + 7.56 - 8.4x = 9.38
Step 2: Combine 3.5 and 7.56
11.06 - 8.4x = 9.38
Step 3: Subtract 11.06 from both sides
11.06 - 8.4x - 11.06 = 9.38 - 11.06
-8.4x = -1.68
Step 3=4: Divide both sides by -8.4
-8.4x/-8.4 = -1.68/-8.4
x = 0.2
<em>Hence the three steps are </em>
<em>Step 1: Distribute 1.2 to 6.3 and –7x </em>
<em>Step 2: Combine 3.5 and 7.56</em>
<em>Step 3: Subtract 11.06 from both sides</em>
