Answer:
60 miles in 5 minutes
Step-by-step explanation:
Given, 720 mph = 720 miles per hour
Hour = 60
Equation: 60x = 5
1. 60 divided by 5 = 12
2. Since you found the x, divide the x (12) by 720
3. 720 divided by 12 = 60
Answer: 60 miles in 5 minutes

Answer:
1. 46.125
Step-by-step explanation: Is your second one in the right format? I don't understand what it is asking. For the first one, however, you need to free the y being multiplied to 8 and so you are going to undo it by dividing 369 by 8.
Which of the following functions best describes this graph?
10
Answer:
A
Step-by-step explanation:
vertex = (-4, -4)
vertex form:
y = a(x-h)^2 + k
__________
y = (x- (-4))^2 + (-4)
y = (x+4)^2 -4
y = (x+4)(x+4) - 4
y = x^2 + 8x + 16 - 4
y = x^2 + 8x + 12
answer: A
Graph the line that passes through the points (-5, 3) and (−1,−1) and determine the equation of the line.
A line can be drawn by joining the plot of the two given points
Please find attached the graph of the line created with MS ExcelThe equation of the line is y = -x - 2Reason:
Given points on the line are (-5, 3) and (-1, -1)
From the given points, the graph of the line can be plotted with MS ExcelThe slope, m, of the line is given as follows
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, we have;
[tex]Slope, \, m =\dfrac{-1 - 3}{-1 - (-5)} = \dfrac{-4}{4} = -1[/tex]
The equation of the line in point and slope form is therefore;
y - 3 = -1·(x - (-5) = -x - 5
In slope and intercept form, we have;
y = -x - 5 + 3 = -x - 2
The equation of the line in slope and intercept form is y = -x - 2Learn more here:

Which ordered pair is a solution to the following:
Y= -2x + 5
Choose 1 answer:
A: Only (2,-9)
B: Only (-2,9)
C: both
D: neither
Answer:
Option B: Only (-2, 9)
Step-by-step explanation:
Given the linear equation, y = -2x + 5:
We'll plug in the given options to see which of the ordered pairs will satisfy the equation:
Substitute option A: (2, -9) into the equation:
y = -2x + 5
-9 = -2(2) + 5
-9 = -4 + 5
-9 = 1 (False statement). Therefore, (2, -9) is not a solution.
Substitute option B: (-2, 9) into the equation:
y = -2x + 5
9 = -2(-2) + 5
9 = 4 + 5
9 = 9 (True statement). Therefore, the ordered pair, (-2, 9) is a solution.
The other two options are irrelevant at this point since we've proven that option B is the correct answer.

Show that the two triangles ABC and DEF are congruent by the
HL theorem.
Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.
The Hypotenuse-Leg theorem states that two right triangles are congruent if and only if their hypotenuses and any of their corresponding legs are congruent. That is to say:
[tex]\overline {AC} \cong \overline {DF}[/tex], [tex]\overline{BC} \cong \overline {EF}[/tex]
[tex]AC = DF, BC = EF[/tex]
[tex]\sqrt{AB^{2}+BC^{2}} = \sqrt{DE^{2}+EF^{2}}[/tex], [tex]BC = EF[/tex]
If we know that [tex]AB = 10[/tex], [tex]BC = 4[/tex], [tex]DE = 10[/tex] and [tex]EF = 4[/tex], then we have the following outcomes:
[tex]\sqrt{10^{2}+4^{2}} = \sqrt{10^{2}+4^{2}}[/tex]
[tex]4 = 4[/tex]
Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.

3 plus four times a number.
Answer:
3 + 4x
Step-by-step explanation:
Let "a number" be x.
Therefore "four times a number" is 4 multiplied by x which is 4x.
Now add 3 for "3 plus".
3 + 4x
Answer:
Our equation would be: 3 + 4x.
Let's say x=8
That would now make our equation:
3 + 4(8) =
Step-by-step explanation:
But let's solve this equation :)
First, we would add 3+4, to get 7.
Then, we would multiply the 7 by 8.
Lastly, we know 7 x 8 = 56
So, 3+4(8)= 56
But we could also create a function statement out of this.
Our statement for this equation would be:
When x equals 8 the answer or in algebraic terms the "output" is 56.

Answer: 100 99/100
Step-by-step explanation: add the 1/2 and 1/5 together by finding a common denominator(10). 1/2 would become 5/10 and 1/5 would become 2/10. 2/10 + 5/10 =7/10. now we're left with (7/10)^2 +3/10 x 5
to do (7/10)^2 you square the top and bottom to give you 49/100.
next we'll do 3/10 x 5 which would equal 15/10. so now all we have left to do is add 49/100 and 15/10. to do this we'll find a common denominator of 100. so well multiply the top and bottom by 10 to give you 150/100.
finally, 49/100 + 150/100 = 199/100 or as a mixed number, 100 99/100
Answer:
1[tex]\frac{99}{100}[/tex]
Step-by-step explanation:
I would start by turning the parentheses fractions into one fraction.
You could do binomial multiplication and get [tex]a^{2} +2ab+b^{2}[/tex] but it might take longer.
So I would just turn them into one fraction by finding the common denominator.
The common denominator here is 10
[tex]\frac{1}{5} (\frac{2}{2} )=\frac{2}{10}[/tex]
[tex]\frac{1}{2} (\frac{5}{5} )=\frac{5}{10}[/tex]
Now add
[tex]\frac{2}{10} +\frac{5}{10} =\frac{7}{10}[/tex]
Now apply: [tex](\frac{a}{b} )^{2} =\frac{a^{2} }{b^{2} }[/tex]
[tex](\frac{7}{10} )^{2} =\frac{7^{2} }{10^{2} } =\frac{49}{100}[/tex]
Now, multiplying the other fraction we get [tex]\frac{3}{10} (5)=\frac{15}{10}[/tex]
Now turn this into a fraction with denominator 100 to add the two fractions
[tex]\frac{15}{10} (\frac{10}{10} )=\frac{150}{100}[/tex]
[tex]\frac{49}{100} +\frac{150}{100} =\frac{199}{100} =1\frac{99}{100}[/tex]
There is also another method to add or subtract fractions without multiplying to get a common denominator in case you are interested:
[tex]\frac{a}{b}[/tex]±[tex]\frac{c}{d}[/tex]=[tex]\frac{ad+bc}{bd}[/tex]

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2.4 h, and Car B traveled the distance in 4 h. Car A traveled 22 mph faster than Car B.
How fast did Car A travel?
(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)
Enter your answer in the box.
Answer:
We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
Solving for x, we obtain:
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.
Step-by-step explanation:
Answer:
Step-by-step explanation:
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
