FIRST PERSON TO ANSWER GET BRAINLYEST Madie drove 200 miles at a speed of 50 miles per hour. Which equation will help you find the number of hours she was driving?
StartFraction 50 miles Over 1 hour EndFraction = StartFraction 200 miles Over question mark hours EndFraction
StartFraction 50 miles Over 1 hour EndFraction = StartFraction question mark hours Over 200 miles EndFraction
StartFraction 200 miles Over 1 hour EndFraction = StartFraction 50 miles Over question mark hours EndFraction
StartFraction 200 miles Over 1 hour EndFraction = StartFraction question mark hours Over 50 miles EndFraction
Answer:
200/50=h
h=number of hours
Step-by-step explanation:
Maddie drove 200 miles at a speed of 50 miles per hour.
As we know
speed = miles/hours
and to calculate we use the formula
Hour = miles/speed
So the equation that helps to find the number of hours she was driving =
h = 200/50
Equation will be h = 200/50
Answer: StartFraction 50 miles Over 1 hour EndFraction = StartFraction 200 miles Over question mark hours EndFraction
Step-by-step explanation:
For constant speed, miles and hours are proportional. One possible equation is ...
_____
I personally like to put the unknown in the numerator, so the equation can be solved in one step. The equation above requires two steps: one to cross-multiply, and one to divide by 50.
I might write the equation as ...
(? hours)/(200 mi) = (1 hour)/(50 mi) . . . . multiply by 200 mi to solve
Another way to write the equation is matching the ratios of times to corresponding miles:
(? hours)/(1 hour) = (200 mi)/(50 mi)
This only requires simplification to solve it: ? = 4.
So it would be A.

1) y = 6
2) x = 3
3) y = - 2/3
4) x = - 6
Step-by-step explanation:So all we have to do is substitute the known 'variable' and solve for the unknown variable.
1) 2(-3) + 3y = 12
3y = 12 + 6
y = 6
2) 4y = (1/3)x - 5
4(-1) = (1/3)x - 5
(1/3)x = 5 - 4
x = 3
3) (x/3) - 2 = y
(4/3) - (6/3) = y
y = (-2/3)
4) 2(x+1) = 5y
2(x+1) = 5(-2)
2x + 2 = - 10
2x = -12
x = -6

An absolute value function can be written as a piecewise function always, sometimes, or never? Your answer should demonstrate an understanding of both types of functions. Explain your answer using complete sentences.
Hello,
Let us choose an element x of the Real Numbers. So x can either be positive or negative. So we have two case to study :
Case 1 : x is positive.
If x is positive, that is, x = 0, 1, 2, 3, ....
then the absolute value gives us the same number : |0| = 0
|1| = 1
|2|= 2
etc.
so the absolute value of x positive equals x : |x| = x
Case 2 : x is negative.
If x is negative, that is, x = - 1, - 2, -3, .....
then the absolue value gives us the opposite value : |-1| = - (-1) = 1
|-2| = -(-2) = 2
|-3| = -(-3) = 3
(Remember the product of two negative sign is a positive signe : -1 * -1 = +1)
And so we can join both cases as a piecewise function, writing :
|x| = [tex]\left \{ {{x=x if x\geq 0 } \atop {x= - x if x<0 }} \right.[/tex]
so x = x if x ≥ 0 and x = - x if x < 0
Finally the answer is : it depend on the function itself. If the function takes both positive and negative value, then the absolute value of the function will be written as a piecewise function. If the function takes only positive or negative value, then it won't be written as a piecewise function.
Triangle ABC is congruent to triangle DEF. Angle B is a right angle, and m∠C = 42°. What is m∠D?
Answer:
Step-by-step explanation: Triangle ABC is congruent to triangle DEF. Angle B is a right angle, and m∠C = 57°. What is m∠D? can someone help plsss
If Triangle ABC is congruent to triangle DEF then measure of angle D is 48 degrees.
Given, Triangle ABC is congruent to triangle DEF.
Angle sum property of triangle: Sum of all the interior angles of the triangle is 180 degrees.
Congruent triangles: When two triangles are congruent they are similar in shape and coincide when superimposed.
Now in triangle ABC,
∠B = 90°
∠C = 42°
Apply angle sum property,
∠A + ∠B + ∠C = 180 degrees
∠A + 90° + 42° = 180°
∠A = 48°
When Triangle ABC is congruent to triangle DEF,
∠A = ∠D
∠B = ∠E
∠C = ∠F
Thus measure of angle D is equal to measure of angle A.
∴∠A = ∠D = 48°

Answer:
y = -2x
Step-by-step explanation:
When it is x is -5, y is double of x multiplied into -1.
Hence, it is y = -2x
We can take a couple examples,
i) When x = -5,
y = -2(-5)
= 10
ii) When x = -10,
y = -2(-10)
= 20

Answer:
2a+2b+4
Step-by-step explanation:
(2a+2b+4)+(3a+8)+(5a+b)=10a+3b+12
Answer:
The perimeter of the triangle is [tex]10a + 3b + 12[/tex], while the two sides is [tex]3a + 8[/tex] and [tex]5a + b[/tex]. To find the missing side, subtract the two known sides from the known perimeter.
[tex](10a + 3b + 12) - (3a + 8) - (5a+b) = 2a+2b+4[/tex]
If we simplify this expression by taking out a factor of [tex]2[/tex], the final answer is: [tex]2a + 2b + 4 = 2(a + b + 2)[/tex].

In Exercises 13-20, find the value of x so that the function has the
given value.
13. f(x) = 6x; f(x) = -24
14. g(x) = -10x; g(x) = 15
15. f(x) = 3x – 5; f(x) = 4
16. h(x) = 14 – 8x; h(x) = -2
Step-by-step explanation:
13. f(x) = 6x; f(x) = -24
6x = -24
x = -4
14. g(x) = -10x; g(x) = 15
-10x = 15
x = -1.5
15. f(x) = 3x – 5; f(x) = 4
3x-5 =4
3x =9
x = 3
16. h(x) = 14 – 8x; h(x) = -2
14-8x=-2
-8x = -16
x = 2
determine whether each equation defines y as a function of x.
2x + y2 = 6
Answer:
NOT a function
Step-by-step explanation:
y^2 (not y2) is "the square of y"
The given 2x + y^2 = 6 can be solved for y as follows:
Subtracting 2x from both sides, we get y^2 = 6 - 2x, whose y-values are y = ±√(6 - 2x). Because there are two y-values associated with each x value, this is NOT a function. In a function there is only one y value for each x value.

6
Step-by-step explanation:
After divide, the solution of the expression is,
⇒ 54 ÷ 9 = 6
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The expression is,
⇒ 54 ÷ 9
Now, We can divide as;

yes, most of the students are minors. 52% percent at least are under 18 years. 52% is more than half, so that would make it so most are minors.

How do I find y?
Answer:
y = 0
Step-by-step explanation:
Parallel lines have equal slopes
Calculate the slopes of both lines and equate them
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 3 ) and (x₂, y₂ ) = (3, y )
m = [tex]\frac{y-(-3)}{3-1}[/tex] = [tex]\frac{y+3}{2}[/tex]
Repeat with (x₁, y₁ ) = (5, - 6 ) and (x₂, y₂ ) = (9, y )
m = [tex]\frac{y-(-6)}{9-5}[/tex] = [tex]\frac{y+6}{4}[/tex]
Equating the 2 expressions
[tex]\frac{y+3}{2}[/tex] = [tex]\frac{y+6}{4}[/tex] ( cross- multiply )
4(y + 3) = 2(y + 6) ← distribute parenthesis on both sides
4y + 12 = 2y + 12 ( subtract 2y from both sides )
2y + 12 = 12 ( subtract 12 from both sides )
2y = 0 , then
y = 0
