Two cars leave San Francisco at the same time traveling in opposite directions. One travels at an
average speed of 74 mph and the other at 78 mph. In how many hours will they be 304 miles apart?
Let x = time of travel for the first car and y = time of travel for the second car.
Then the system that
models the problem is {74x + 78y=304}
Solve the system by using the method of addition.

Answer:
(c) factoring and the zero-product principle
Step-by-step explanation:
Factoring is always an efficient method of solving a quadratic, if it has nice integer factors that can be easily identified. Here, the two prime factors of 35 have a sum of 12, so the factored form is easily found to be ...
(x +5)(x +7) = 0
This basically shows you the solutions are x=-5 and x=-7 "by inspection" in one step.
By contrast, the quadratic formula has 4 multiplications, a division, a square root, and 3 additions. That's a significant amount of arithmetic to get to the answers.
Factoring is the most efficient way to solve this quadratic.
Determine the value of x.

Step-by-step explanation:
Given
Length of the hypotenuse of the right angled triangle (h) = 2.5 cm
Length of one of the side (a) = 1.5 cm
Let the length third side be 'b' cm
By Pythagoras theorem
h² = a² + b²
Adding Values on both sides
⇒ (2.5)² = (1.5)² + b²
⇒ 6.25 = 2.25 + b²
⇒ 6.25 - 2.25 = b²
⇒ 4 = b²
⇒ √4 = b
⇒ 2 = b
⇒ b = 2

Answer:
(A, B, C) = (2, 5, 2)
Step-by-step explanation:
Undo the square operation by taking the square root. Both the positive and negative square roots are solutions to the equation.
[tex]c -2 = \pm\sqrt{50}[/tex]
Add 2 to both sides of the equation:
[tex]c = 2\pm\sqrt{50}[/tex]
Simplify the square root:
[tex]c=2\pm\sqrt{25\cdot2}=2\pm\sqrt{25}\cdot\sqrt{2}\\\\\boxed{c=2\pm5\sqrt{2}}\qquad\text{A=2, B=5, C=2}[/tex]

Answer:
(x -1/4)(x -1)(x +1)
Step-by-step explanation:
Pairs of coefficients have the same ratio, so it is likely that you can factor this by grouping pairs of terms.
x³ -x -1/4x² +1/4 = (x³ -x) -(1/4x² -1/4) . . . . . . note the signs
= x(x² -1) -1/4(x² -1)
= (x -1/4)(x² -1)
The difference of squares (x² -1) is a special form that has factors (x -1)(x +1)
Your factoring is ...
(x -1/4)(x -1)(x +1)

The diameter of Jupiter is about 1.4 x 10 5 kilometers. The diameter of Mars is snout 6.8 x 10 3 kilometers. About how many times greater is Jupiter’s diameter of Mars
Answer:
Jupiter's diameter is "about" 21 times greater than Mars with an exact answer of around 20.588
Step-by-step explanation:
Jupiter = 1.4 x [tex]10^{5}[/tex] = 140,000
(1.4 "plus 5 places" is how I think of it to make it easier)
Mars = 6.8 x 10³ = 6,800
To find how many times greater Jupiter is than Mars we can divide tje diameter of Jupiter by Mars:
140,000 / 6,800 = 20.588235 etc
I am not sure how far you are rounding, but Jupiter's diameter is "about" 21 times greater than Mars

Find the value of x......
Answer:
100
Step-by-step explanation:
Since, line a is parallel to line t ( from diagram ).
x - 30 and 70 are alternate interior angles.
Reason : -
Alternate interior angles are equal when two lines are parallel and cut by a transversal line.
x - 30 = 70
x = 70 + 30
x = 100

write 49/7 as a whole number
Answer:
7
Step-by-step explanation:
the fraction 49/7 is the same as the problem 49÷7
If you do the problem, you get 7, and if you want to check you could do the inverse- 7x7=49. Since that checks out, 7 is your answer.

100 points !!!!
Answer:
D
Step-by-step explanation:
The graph G(x) is moved to the left by 1.
So it would be G(x) = (x+1)^2
The equation of the blue graph is,
⇒ g (x) = (x + 1)²
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The equation of the red graph is,
⇒ f (x) = (x)²
Since, The blue graph is shift 1 unit from red graph.
Hence, The equation of the blue graph is,
⇒ g (x) = (x + 1)²
Thus, The equation of the blue graph is,
⇒ g (x) = (x + 1)²
