Step-by-step explanation:
a car travels along the highway to yuma at steady speed. when it begins, it is 400 miles from yuma. After 7 hours, it is 59 miles from yuma. which function describes the cars distance from yuma?
Answers
The car's position can be described with the linear function below:
y = (-48.7 mi/h)*x + 400 mi
Which function describes the car's distance from Yuma?
We know that the car is initially at a distance of 400 miles from Yuma. We also know that the car moves at a constant rate (steady speed) then its position will be described by a linear equation:
y = a*x + b
Where y is the distance, a is the slope and b is the y-intercept.
Knowing the initial distance, we can write:
y = a*x + 400mi
And we know that after 7 hours, the car is at 59 mi, then we can write:
59 mi = a*7h + 400mi
59mi - 400mi = a*7h
-341 mi = a*7h
-341mi/7h = a
-48.7mi/h = a
Then the equation that describes the distance from Yuma is:
y = (-48.7 mi/h)*x + 400 mi

Answer:
-30
Step-by-step explanation:
7x-4=-28-6=-34+4=-30
Pls mark as brainliest!!!!!
Answer:
The answer for this is -30.
Step-by-step explanation:
Basically, you start out with solving the equation from left to right (as always). First, you multiply 7* -4, and you get -28. Then you have -28 - |-6| + |4|. Now, |-6| is equal to 6, since it's the absolute value of -6. |4| is equal to 4 for the same reason as well. That leaves you with -28 - 6 + 4. Now you just solve left to right. -28 - 6 is -34, so then you have -34 + 4, which is equal to -30.

Rectangles P, Q, R, and S are scaled copies of one another. For each pair, decide if the scale factor from one to the other is greater than 1, equal to 1, or less than 1. Four rectangles, labeled P, Q, R and S. Each rectangle is a scaled copy of one another. Ranked in order from least to greatest, the area of the rectangles are as follows: the area of P is equal to S, which are less than the area of Q, which is less than the area of R. From P to Q from P to R from Q to S from Q to R from S to P from R to P from P to S
Answers
I attached a diagram that will aid the understanding of the question.
Firstly, I would love to review what a scale factor is before going into the question.
If you have two shapes that are similar, that is they have corresponding angles, then the scale factor of one to the other is simply the ratio of any two corresponding lengths in the two similar geometric figures.
Looking at these figures in the question, we see that R is an enlargement of the other rectangles while Q is an enlargement of P and S. With this information we can answer the questions:
1. From P to Q, the scale factor greater than one because Q is bigger than P.
2. From P to R, the scale factor is greater than one for the same reason.
3. From Q to S, the scale factor is less than one because S is smaller than Q.
4. From Q to R, the scale factor is greater than one because R is bigger than Q.
5. From S to P, the scale factor is equal to one because they are equal.
6. From R to P, the scale factor is less than one because p is smaller than R.
7. From P to S, the scale factor is equal to one because they are equal.

Which of the following is equivalent to -(7/4) ?
A. 7/-4
B. -7/-4
C. 4/-7
D. 7/4
Answers
Answer:
A
Step-by-step explanation:
-(7/4) equals -7/4 or negative seven forths. Its doesn't matter where the negative sign is as long there's only 1 of them and that its still 7/4.
So through process of elimination, we take out B because theres 2 negative, which make a positive, our answer is negative
C is wrong because its 4/7, not 7/4
D is wrong because it's positive, leaving us with A

An ostrich is being chased by a cheetah,
The ostrich is running at 44 feet per
second and the cheetah at 110 feet per
second. If the two started at the same
place and the ostrich got a 60-second
head start, how many seconds will it be
before the cheetah catches it?
Answers
Answer:
40 seconds
Step-by-step explanation:
(ostrich speed * seconds) + head start = (cheetah speed * seconds)
44x + (44 * 60) = 110x
44x + 2640 = 110x
2640 = 66x
x = 40
No. of seconds before cheetah catches ostrich = 40 seconds
What is speed?Speed tells us how slow or fast an object moves. It describes the distance travelled divided by the time taken to cover the distance.
Speed is directly Proportional to Distance and Inversely proportional to Time.
Speed = Distance/Time
Given,
Speed of ostrich = 44 feet per second
Speed of cheetah = 110 feet per second
Starting point is same
Ostrich got 60 second head start
Distance travelled by ostrich in 60 second = 44 × 60 = 2640 feet
let S be the number of seconds that it will take the cheetah to catch the ostrich
Distance covered by cheetah = 110S
Distance that the ostrich will cover before being caught is 2640 + 44S
According to the question
110S = 2640 + 44S
110S - 44S =2650
66S = 2640
S = 2640/66
S = 40 seconds.
Hence, It will be 40 seconds before cheetah catches the ostrich.

Solve for x.
-18x + 21 > -15 OR 20x – 13 >27
Answers
Answer:
C
Step-by-step explanation:
-18x + 21 > -15 /// x = 2
20x – 13 >27 /// x = 2
The solution of inequality -18x + 21 > -15 OR 20x – 13 > 27 is x ∈ (- ∞, ∞), so option E is correct.
What is inequality?An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.
Given:
-18x + 21 > -15 or 20x – 13 >27
Solve the first inequality as shown below,
-18x + 21 > -15
-18x + 21 - 21 > -15 - 21 (Subtract 21 from both sides)
-18x > -36
-18x / -18 > -36 / -18 (Divide by -18 into both sides, the inequality sign changes as the value will become positive)
x < 2
Similarly, solve the second inequality,
20x – 13 > 27
20x > 40
x > 2
Thus, the solution will be x < 2 ∪ x > 2 or x ∈ (- ∞, ∞)
