The answer is 7. You can solve it by going through all the answers and testing the math. 7 x 15$ = 105 so add that to 3 x 25 = 75 and it proves it equals 180$.
Answer:
185
Step-by-step explanation:
11×35=385-200= 185
Answer:
(1)-
b1 =~3.4
bo= ~ 82.8
(2)- ý=[82.8]+[3.4] x
(3)- The change in annual sales ($1000) for every year of experience is= 3.4
(4)-r^2=~ 0.847
Estimated annual sales= $110514
Step-by-step explanation:
(1)- b1 = 3.4606
=~3.4
bo = 82.8296
= ~ 82.8
(2)-
ý=[82.8]+[3.4] x
(3)-The change in annual sales ($1000) for every year of experience is= 3.4
(4)- r^2 = 0.84776
=~ 0.847
Percentage of the variation in annual sales can be explained by the years of experience
of the salesperson 84.7%.
Estimated annual sales
= 82.8296 + 3.4606 × 8 ($ 1000).
= 110.5144 ( $1000)
= $ 110514:4
= $110514
Yes, 4(x-2) is 4 times x-2 which using the distributive property gives you 4x-8 because 4 times x is 4x and 4 times -2 is -8 so you would always get 4x-8
Answer:
y = 4x + 7
Step-by-step explanation:
the equation for a line is y = mx+b
the y intercept is (0,7)
so in the equation x= 0 and y= 7 and the slope is m, thus m= 4
7= (4)(0)+b
now solve for b
7 = 0 +b
7= b
so the equation of the line would be without the x and y points
y = 4x + 7
