Answer:820
Step-by-step explanation:
Since he got $500 the first week multiply 80x4 which is 320+500 is 820$
We can use the points (-10,0) and (-13,3) to solve.
Slope formula: y2-y1/x2-x1
= 3-0/-13-(-10)
= 3/-3
= -1 (Answer)
Hope This Helped! Good Luck!
Not always it depends on what kind of problem you get. Sometimes you have get a problem that does not have multiplication so then you'd start with division instead.. Get what I'm saying lol? Maybe that helps.
The measure of EF from the given diagram is 6 units
<h3>Secant secant theorem</h3>
The theorem states that if two secants are drawn from an external point to a circle, then the product of the measures of one secant's external parts is the same as the product of the other external part.
Mathematically according to the given figure;
4(4+2x) = 5(5+x)
Expand
16 + 8x = 25 + 5x
Collect the like terms
8x - 5x = 25 - 16
3x = 9
Divide both sides by 3
3x/3=. 9/3
x = 3
Find EF
EF = 2x
EF = 2(3) = 6
Hence the measure of EF from the given diagram is 6 units
