1a) x = 5, y = 2
b) x = 2, y = -1
2a) x = 2, y = 1
b) x = -0.3, y = 2.4
3 don’t know sorry
4a) x = -7, y = 3
b) x = -3.2, y = -23.8
<u>✨</u><u>Answer:</u><u>✨</u>
9 3/4 (simplest form)
<u>✨Step-by-step explanation:✨</u>
<em><u>1. Convert decimal into fraction:</u></em>
9.75 = 975/100
<u><em>2. Simplify:</em></u>
975/100 = 39/4 = 9 3/4
<em>A. Reduce fraction to lowest terms (25 is the greatest common divisor of 975 and 100. Reduce by dividing both numerator and denominator by 25):</em>
975/100 = <u>975 ÷ 25</u> = 39/4
100 ÷ 25
<em>B. Convert improper fraction to mixed number:</em>
39/4 = 9 3/4
(39 ÷ 4 = 9 remainder 3)
Answer:
y = 2x + 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = ( 0, 4) ← 2 points on the line
m = = = = 2
the line crosses the y- axis at (0, 4 ) ⇒ c = 4
y = 2x + 4 ← equation of line
Answer:
<em>D. 69 Km</em>
Step-by-step explanation:
<u>Scaling</u>
Maps usually represent real areas on the field, but since they cannot fit in pieces of paper, we use scales where sizes and distances are all proportional to the real measurements.
On the map of the question, we know 1 cm represents 30 Km. It means that we can know approximate real distances by measuring the distances on the paper or blueprints.
Two cities are 2.3 cm apart on the map, it means that they are really 2.3*30 =69 Km apart
