. Next, multiply 
by 
to create a fraction with a common denominator in order to subtract from 
. The problem will now look like 
.
Then, simplify the terms in the problem by first multiplying and , which will look like 
. The next step is to combine the numerators over the common denominator, which will look like 
.
Next, simplify the numerator, and to simplify the numerator start by factoring 3 out of 
, which will look like 
. Then, subtract 14 from -7, which will look like . The final answer will be .
The slope-intercept form is y = 2x-3.
<u>Step-by-step explanation</u>:
Given,
- The equation of the line is y=2x+7.
- The general equation of the line is in the form y= mx+c.
- where 'm' represents the slope of the line.
<u>Comparing the given equation with general equation, it can be determined that</u> :
m = 2 and c = 7 (y-intercept).
The given line passes through the point (3,3) which is equal to (x1,y1)
Therefore, x1=3 and y1=3.
Substitute m=2 and the values of (x1,y1) in the slope-intercept form,
The slope-intercept form is (y-y1) = m (x-x1)
(y-3) = 2(x-3)
y = 2x-6+3
y = 2x-3
Answer:20 In
Step-by-step explanation:
Diameter=40 In
radius=diameter ➗ 2
radius=40 ➗ 2
radius=20 In
Answer:
18 and 72
Step-by-step explanation:
the smaller part can be assigned as x while the larger will be 4x. Both numbers need to add up to 90, giving the equation: 4x+x = 90
Solve:
4x+x = 90
5x = 90
x = 18
4x = 72
