Answer: y = -1

Step-by-step explanation:

Assuming "distance from the origin is one unit" means distance on the x axis, a vertical straight line having an x-intercept of -1 would satisfy thede requirements. y = -1 isn't much of an equation, but it goes through (-1,2) and is 1 unit (-1) from the origin.

Answer:

y = -1/2x + 3/2

Step-by-step explanation:

(2-0)/(-1-0) = -1/2

2 = -1/2(-1) + b

2 = 1/2 + b

b = 3/2

1 3/4 − 4/5 = 35 twentieths − what fraction???<br><br>Plss help will give brainliest :)

7nadin3 [17]

let's firstly convert the mixed fractions to improper fractions and then to do away with the denominators, let's multiply both sides by the LCD of all denominators.

$\stackrel{mixed}{1\frac{3}{4}}\implies \cfrac{1\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{7}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{7}{4}-\cfrac{4}{5}=\cfrac{35}{20}-\boxed{?}\implies \stackrel{\textit{multipling both sides by }\stackrel{LCD}{20}}{20\left( \cfrac{7}{4}-\cfrac{4}{5} \right)=20\left( \cfrac{35}{20}-\boxed{?} \right)} \\\\\\ 35-16=35-20\boxed{?}\implies 19=35-20\boxed{?}\implies -16=-20\boxed{?} \\\\\\ \cfrac{-16}{-20}=\boxed{?}\implies \cfrac{4}{5}=\boxed{?}$

If Mike does his mathematics homework today, the probability that he will do it tomorrow is 0.8. The probability that he will do

harina [27]

Answer:

d. 14:11

Step-by-step explanation:

There is a 7 in 10 chance that Mike does his homework today and a 8 in 10 chance he will do it tomorrow, the probability that he will do it both today and tomorrow is:

$P = \frac{7}{10}* \frac{8}{10}\\P=\frac{56}{100}=0.56$
