Answer:
1
Step-by-step explanation:
First, we can find the equation of the parabola. The standard form of a parabola is ax^2 + bx + c,
where c is the y-intercept. The y-intercept on the graph is -5, and every option starts with x^2, so the equation must be x^2 - 5. This rules out options 3 and 4.
Next, we can find the equation of the line. The options are all given in slope-intercept form: y = mx + b, where b is the y-intercept. The y-intercept on the graph is 1, and option 1 has 1 in the place of b. Therefore, option 1 is the answer.
Answer: false
Step-by-step explanation: Compare -5 and -32. They do not equal each other.
First you need to find a common denominator. 11/15 = 22/30
3/10= 9/30
9/30+22/30= 1 1/30
Hope this helps!
18 and 3/7
Because i can write by phone. So just write 18 in the left side of 3/7
A. 7 hours ago the temperature was 7 * 1,5 = 10,5 degrees more, so if now it's 0, then it was 10,5 degrees 7 hours ago.
b. in six hours it will be 6 * 1,5 = 9 degrees less, so if it's 0 now, then it will be -9 degrees in 6 hours.
c. the temperature was reading 6 degrees 4 hours ago because:
x * 1.5 = 6 / ÷1.5 (both sides)
x = 4
d. -8 is expected to be in 5 hours and 15 minutes because:
x * 1.5 = 8 / ÷1.5 (both sides)
x = 5 1/3
