what is the formula for speed when speed isnt given
Step-by-step explanation:
what do you mean lf speed is not given what we have tofind
Answer:
v = d/t, perhaps.
Step-by-step explanation:
Velocity (speed) is defined as distance traveled divided by the time it takes to travel that distance.
This gives an average speed. For example, I'll be taking a trip tomorrow of about 150 miles. If it takes me 3 hours, my average speed is v = 150/3 = 50 miles per hour.
That does not mean my speed is constantly 50 miles per hour; I sometimes go slower than that (maybe even stopping for red lights!), and sometimes I'll be going faster than that.
A lot of school math problems assume a constant speed.
Find f(g(-4)) if f(x) =7/x+2
and g(x) = (x + 5)^2. Options: -5/2 , -7/2 , 37/4 , 7/3
Answer:
7/3
Step-by-step explanation:
f(x) =7/(x+2)
g(x) = (x + 5)^2
f(g(-4))=
First find g(-4)
g(-4) = (-4+5)^2
=(1)^2 =1
Then find f(1)
f(1)= 7/(1+2)
= 7/3

in the figure below the measure of <1=5x°, the measure of <2=y°, and the measure of <3=85°. Find the value of each variable.
(for the first one <1=5x° I found out x=17 so I just need the rest if you can)
Answer:
y=95
Step-by-step explanation:
17x5=85
180-85=95
y=95
Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles. The value of x and y is 17 and 95, respectively.
What are vertical angles?Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles.
The measure of ∠1 and ∠3 will be equal since the two angles are vertical angles. Therefore, we can write.
∠1 = ∠3
5x° = 85°
x = 85° / 5
x = 17°
Also, the sum of measures ∠1 and ∠2 will be equal to 180°, this is because the two angles form a pair of linear angles. Therefore, we can write,
∠1 + ∠2 = 180°
5x + y = 180°
Substitute the value of x,
5(17°) + y = 180°
85° + y = 180°
y = 180° - 85°
y = 95°
Hence, the value of x and y is 17 and 95, respectively.

What is the slope of the line passing through the points (2, 4) and (5, 6)?
Answer:
C. 2/3
Step-by-step explanation:
To find the slope of a line from two points, use this formula.
[tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]
The variable 'm' means slope in algebra.
y² means the second y-coordinate and y^1 means the first y-coordinate.
Based on the previous definition, it should be easy to figure out what x² and x^1 mean.
[tex](2,4),(5,6)[/tex]
[tex]m=\frac{6-4}{5-2} =\frac{2}{3}[/tex]
Therefore, the slope of the line passing through the points (2,4) and (5,6) is 2/3.

Which of the following is the graph of f(x) = |xl translated 2 units right, 2 units up, and dilated by a factor of 1/3?
Answer:
Its the C graph
Step-by-step explanation:
Help pleaseeeeeeeeeee
Answer:
3(x+5)
hope it helps you
Pls answer these questions
Step-by-step explanation:
Objective; Translating points
A translation is when we moving figures and points. We can represent a transformation algebraically and geometrically.
Algebracially:
[tex](x + h)[/tex]
where h is the amount of units we move right or left
and
[tex](y + k)[/tex]
where k is the amount of units we move up or down
For 1. We are asked to translate the figure 3 units up and 7 units to the left.
7 units to the left is the same as subtracting 7 . from x valyes. and 3 units up is is same as adding 3 units to the y values, so subtract 7 from every x coovalues. and add 3 to every y value. is
Our new coordinates
E is (-5,3) F is (-2,4) G is (-3,5) H is (-5,5).
2. 6 units right and 8 units up is basically add 6 to every x value and add 8 to every y value.
So our new coordinates is
T' (1,3)
U' (4,3)
V'(4,5)
W'(1,5)

8) v = -3
9) m = 4
Explanation:
8)
[First distribute the factored terms on the left side of the equation]
2(v + 4) + 3(4v + 5) = -19 →
2(v) + 2(4) + 3(4v) + 3(5) = -19 →
2v + 8 + 12v + 15 = -19 →
[Next, add the like terms together]
(2v + 12v) + (8 + 15) = -19 →
14v + 23 = -19 →
[Subtract 23 from both sides to isolate the constant term]
14v + 23 – 23 = -19 – 23 →
14v = -42 →
[Lastly, divide both sides by 14 in order to obtain the value of v from the coefficient of 14 in 14v]
14v / 14 = -42 / 14 →
v = -3
9)
[Start by distributing the factored term on the left side of the equation]
2(m – 1) = 10 – m →
2m – 2 = 10 – m →
[Next, add m to both sides in order to isolate the m term and remove -m from the right side of the equation]
2m – 2 + m = 10 – m + m →
3m – 2 = 10 →
[Add 2 to both sides to isolate the constant term and remove -2 on the left side of the equation]
3m – 2 + 2 = 10 + 2 →
3m = 12 →
[Finally, divide by 3 on both sides in order to reduce the coefficient of 3 in 3m to get m]
3m / 3 = 12 / 3 →
m = 4

R 3. The mean of 4 numbers is 8. Three of the numbers add up to 22. What is the last number?
let the last number be x

[tex] \boxed{mean = \frac{sum \: \: of \: \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]
So,
[tex] \hookrightarrow \: 8 = \dfrac{22 + x}{4} [/tex]
[tex] \hookrightarrow \: 8 \times 4 = 22 + x[/tex]
[tex] \hookrightarrow \: 32 = 22 + x[/tex]
[tex] \hookrightarrow \: x = 32 - 22[/tex]
[tex] \hookrightarrow \: x = 10[/tex]

which angles of the triangles measure to a 90 degree
Answer:
A right angle has a value of 90 degrees (90∘). A right triangle is a triangle in which one angle is a right angle. The relation between the sides and angles of a right triangle is the basis for trigonometry.
The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b). Side a may be identified as the side adjacent to angle B and opposed to (or opposite) angle A. Side b is the side adjacent to angle A and opposed to angle

(EASY) In a rectangle, the length is 5 metres more than the width The perimeter of the rectangle is 70 metres Calculate the measurments for the length and width
Answer:
15 m and 20 m
Step-by-step explanation:
Let the width be x
Length = x + 5
Perimeter = 2(l + b)
70 = 2(x + 5 + x)
70/2 = 2x + 5
35 = 2x + 5
35 - 5 = 2x
30 = 2x
30/2 = x
15 = x
Length = x + 5 = 20 m
Breadth = x = 15 m
PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE HELP DECIMAL WORD PROBLEM INTO EQUATION
Answer:
136 miles
Step-by-step explanation:
Write an equation to represent the cost of the rental, and then solve the equation to find the number of miles.
Let x = number of miles.
The total cost is the cost per mile plus the base fee.
1 mile costs $0.90
2 miles cost $0.90 * 2
x miles cost $0.90 * x, or simply 0.9x
The base fee is $16.95, so the total to rent for x miles is 0.9x + 16.95
The equation
c = 0.9x + 16.95
gives you the cost, c, for a rental of x miles.
We are told the total cost was $139.35. Replace c with 139.35, and solve for x, the number of miles.
139.35 = 0.9x + 16.95
Switch sides.
0.9x + 16.95 = 139.35
Subtract 16.95 from both sides.
0.9x = 122.4
Divide both sides by 0.9
x = 122.4/0.9
x = 136
Answer: 136 miles
Write the equation of a line in slope-intercept form, y = mx + b, between the following
points: (2, 5) and (-4,-4).
Answer:
[tex]y = \frac{3}{2} x + 2[/tex]
Step-by-step explanation:
In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} } [/tex]
Using the formula above,
[tex]slope = \frac{5 - ( - 4)}{2 - ( - 4)} [/tex]
[tex]m = \frac{5 + 4}{2 + 4} [/tex]
[tex]m = \frac{9}{6} [/tex]
[tex]m = \frac{3}{2} [/tex]
Substitute the value of m into the equation:
[tex]y = \frac{3}{2} x + b[/tex]
To find the value of b, substitute a pair of coordinates into the equation.
When x= 2, y= 5,
[tex]5 = \frac{3}{2} (2) + b[/tex]
5= 3 +b
b= 5 -3
b= 2
Thus, the equation of the line is [tex]y = \frac{3}{2} x + 2[/tex].
