Solve this equation for y: 7y=12x (1 point) Responses
y=12x−7
y=7/12x
y is equal to 7 over 12
x y=12x+7
y is equal to 12 x plus 7
y=12/7x
y = 7/12x
Solve this equation for y: 7y=12x (1 point) Responses y=12x−7 y is equal to 12 x minus 7 y=712x y is equal to 7 over 12 x y=12x+7 y is equal to 12 x plus 7 y=127x
The correct answer is:
y = 12x / 7
8. Change the equation from standard form to slope-intercept form by solving for y. 8x−4y=24 Determine who changed the equation correctly: Bob: Subtract 8x from both sides: −4y=−8x+24 Divide by -4 on both sides: y=2x−6 Bill: Subtract 8x from both sides: −4y=16x Divide by -4 on both sides: y=−4x Bud: Subtract 8x from both sides: −4y=−8x+24 Divide by -4 on both sides: y=2x+24 (1 point) Responses Bill Bill Bob Bob None of them are correct None of them are correct Bud
The correct answer is:
Bob: Subtract 8x from both sides: -4y = -8x + 24
Divide by -4 on both sides: y = 2x - 6
Solve 3x+2b=6c for x. Step 1: 3x+2b−2b=6c−2b subtract 2b from both sides Step 2: 3x=6c−2b combine like terms/simplify Step 3: 3x3=6c3−2b divide by 3 on both sides to get x isolated Step 4: x=2c−2b simplify/final answer Which statement is TRUE? (1 point) Responses The process has an error. The correct answer is x=2c−23b The process has an error. The correct answer is x is equal to 2 c minus 2 thirds b The process has an error. The correct answer is x=4bc3 The process has an error. The correct answer is x is equal to the fraction with numerator 4 b c and denominator 3 The process is correct. The process is correct. The process has an error. The correct answer is x=−4b−c
The correct answer is:
The process is correct. x = 2c - 2b
Suppose that the water level of a river is 45 feet after 3 days of no rain and 10 feet after 10 days of no rain. Given the two points we know: (3, 45) and (10, 10), what would the point slope equation look like?(1 point) Responses (y−45)=−5(x−3) open paren y minus 45 close paren is equal to negative 5 times open paren x minus 3 close paren (y−10)=−5(x+10) open paren y minus 10 close paren is equal to negative 5 times open paren x plus 10 close paren (y−3)=−5(x−45) open paren y minus 3 close paren is equal to negative 5 times open paren x minus 45 close paren (y+10)=−5(x−10)
The point-slope equation would look like:
(y - 45) = -5(x - 3)
13. Suppose that the water level of a river is 45 feet after 3 days of no rain and 10 feet after 10 days of no rain. The river was 60 feet before the drought began.(4 points)
