Answer:
15in
Step-by-step explanation:
Convert the 15 ft to inches (180) and then set up the proportion.\frac{1}{12} = \frac{x}{180}121=180x . Cross multiply to get that 12x = 180 and x = 15 inches.
Answer:
Opt B. y=5-3x
Step-by-step explanation:
We need to write the given equation in slope-intercept form, so we can obtain the slope and the 'y' axis intercept point.
To do this, we need to isolate 'y' variable with a possitive sign, hence we perform the following operation:
Subtraction of -5 in both sides of equality sign.
-y=3x-5
Lets multiply by -1 the equation from above:
y= 5-3x.
From the above we can find the slope, is the coefficient of x. in this case -3
And the y-intercept point is 5.

2.5x3x(1/2)= 3.75
7.2x(1/2)=3.75
3.5=3.5
Answer:
B. -7
Step-by-step explanation:
Formula to find slope is (y2-y1) / (x2-x1)
Here we have 4 points to choose from, but we only need 2. I will use the first 2 points.
The y2 is 7, the y1 is 14, the x2 is 3, the x1 is 2.
Substitute these numbers into the formula.
(7-14) / (3-2)
^ This is basically -7/1, or -7.
Answer:
No, he is not correct.
Step-by-step explanation:
0.23 × 2.07 = 0.4761
Multiply 0.23 and 2.07 to get 0.4761.
0.4761=0.04761
Compare 0.4761 and 0.04761.
False
