Answer:157/10
Step-by-step explanation:
Make 15 into an improper fraction (every number is a fraction over 1) so multiply the numerator(15) and the denominator(1) by 10 to get 150/10 then add 150/10 to 7/10 to get 157/10
Answer:
<em>Option </em><em>3</em>
Step-by-step explanation:
Rewriting input as fractions if necessary:
3/8, 3/20
For the denominators (8, 20) the least common multiple (LCM) is 40.
LCM(8, 20)
Therefore, the least common denominator (LCD) is 40.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
3/8 = 3/8 × 5/5 = 15/40
3/20 = 3/20 × 2/2 = 6/40
Solve the equation by replacing x with -7 and then -1.
Then subtract the two to find the difference and divide that by the difference between -7 and -1.
f(-7) = -7^2 + 2(-7) -8 = 49 -14 -8 = 27
f(-1) = -1^2 + 2(-1) -8 = 1 -2 - 8 = -9
Difference between 27 and -9 = -36
Difference between -1 and -7 = -6
Rate of change = -36 /-6 = 6
Answer:
∠2 = 152
Step-by-step explanation:
A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.
That means that 180-28, will give us our other angle.
