Find the slope of the line (-1,-4) , (-4,2)
Given that B, D and F are midpoints, find the length of segment DA.
Answer:
The length of segment DA is 15 units
Step-by-step explanation:
The segment which joining a vertex of a triangle and the midpoint of the opposite side to this vertex is called a median The point of intersection of the median of a triangle divides each median into two parts the ratio between them is 1: 2 from the base, which means the length of the median is 3 times the part from the baseLet us use this rule to solve the question
In Δ AEC
∵ D is the midpoint of EC
∴ AD is a median
∵ B is the midpoint of AC
∴ EB is a median
∵ F is the midpoint of AE
∴ CF is a median
→ The three medians intersected at a point inside the triangle,
let us called it M
∵ AD ∩ EB ∩ CF at M
∴ M is the point of intersection of the medians of Δ AEC
→ By using the rule above
∴ AD = 3 MD
∵ MD = 5
∴ AD = 3(5)
∴ AD = 15 units

jake drove 320km in the same time that jenna drove 360 km. if jenna drove on average 10km/h faster than jake, calculate her average speed. solve using a rational eqation.
Answer:
Jenna’s average speed is 90 km/h
Step-by-step explanation:
Here, we want to calculate Jenna’s average speed
Mathematically;
time = distance/speed
Let Jenna’s speed be x km/h
It means that Jake’s will be (x-10) km/h since Jenna’s speed is 10 km/h faster
Time taken for Jake is 320/(x-10)
Time taken for Jenna is 360/x
Since the time is equal;
Then;
320/(x-10) = 360/x
320(x) = 360(x-10)
320x = 360x - 3600
360x-320x = 3600
40x = 3600
x = 3600/40
x = 90 km/hour
Solve for u in terms of r, s, t, and v.
rs= –tvu
Answer:
u = -rs/tv
Step-by-step explanation:
We are given that:
rs = -tvu
Finding the value of u;
We simply divide either side by: -tv
∴ (rs) ÷ (-tv) = (-tvu) ÷ (-tv)
u = (rs) ÷ (-tv) = [tex]-\frac{rs}{tv}[/tex]

? | 1.5

0 | ?

Equation: y = ____ x + _____
Answer:
All results in the explanation
Step-by-step explanation:
To make the equation of the line, we only need two points. Select from the table the points (-1,4) and (3,9).
First, find the slope of the line:
We know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]
Substituting:
[tex]\displaystyle m=\frac{9-4}{3+1}=\frac{5}{4}[/tex]
This value is used in the slope-point form of the line:
[tex]\displaystyle y-k=\frac{5}{4}(x-h)[/tex]
Where (h,k) is a point from the table, select for example (3,9):
[tex]\displaystyle y-9=\frac{5}{4}(x-3)[/tex]
Operate:
[tex]\displaystyle y=\frac{5}{4}\cdot x-\frac{5}{4}\cdot 3+9[/tex]
[tex]\displaystyle y=\frac{5}{4}\cdot x+\frac{-15+36}{4}[/tex]
The equation of the line is:
[tex]\boxed{\displaystyle y=\frac{5}{4}\cdot x+\frac{21}{4}}[/tex]
Now complete the table.
For x=0:
[tex]\displaystyle y=\frac{5}{4}\cdot 0+\frac{21}{4}[/tex]
[tex]y=\frac{21}{4}[/tex]
For x=15
[tex]\displaystyle y=\frac{5}{4}\cdot 15+\frac{21}{4}[/tex]
[tex]\displaystyle y=\frac{75}{4}+\frac{21}{4}=\frac{96}{4}=24[/tex]
y=24
For y=1.5, find x:
[tex]\displaystyle 1.5=\frac{5}{4}\cdot x+\frac{21}{4}[/tex]
Operate:
[tex]\displaystyle 1.5-\frac{21}{4}=\frac{5}{4}\cdot x[/tex]
Multiply by 4:
[tex]\displaystyle 6-21=5 x[/tex]
Solve:
[tex]x=-15/5=-3[/tex]
x=-3
Answer:
All results in the explanation
Step-by-step explanation:
To make the equation of the line, we only need two points. Select from the table the points (-1,4) and (3,9).
First, find the slope of the line:
We know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
\begin{gathered}\displaystyle m=\frac{y_2-y_1}{x_2-x_1}\\\end{gathered}m=x2−x1y2−y1
Substituting:
\displaystyle m=\frac{9-4}{3+1}=\frac{5}{4}m=3+19−4=45
This value is used in the slope-point form of the line:
\displaystyle y-k=\frac{5}{4}(x-h)y−k=45(x−h)
Where (h,k) is a point from the table, select for example (3,9):
\displaystyle y-9=\frac{5}{4}(x-3)y−9=45(x−3)
Operate:
\displaystyle y=\frac{5}{4}\cdot x-\frac{5}{4}\cdot 3+9y=45⋅x−45⋅3+9
\displaystyle y=\frac{5}{4}\cdot x+\frac{-15+36}{4}y=45⋅x+4−15+36
The equation of the line is:
\boxed{\displaystyle y=\frac{5}{4}\cdot x+\frac{21}{4}}y=45⋅x+421
Now complete the table.
For x=0:
\displaystyle y=\frac{5}{4}\cdot 0+\frac{21}{4}y=45⋅0+421
y=\frac{21}{4}y=421
For x=15
\displaystyle y=\frac{5}{4}\cdot 15+\frac{21}{4}y=45⋅15+421
\displaystyle y=\frac{75}{4}+\frac{21}{4}=\frac{96}{4}=24y=475+421=496=24
y=24
For y=1.5, find x:
\displaystyle 1.5=\frac{5}{4}\cdot x+\frac{21}{4}1.5=45⋅x+421
Operate:
\displaystyle 1.5-\frac{21}{4}=\frac{5}{4}\cdot x1.5−421=45⋅x
Multiply by 4:
\displaystyle 6-21=5 x6−21=5x
Solve:
x=-15/5=-3x=−15/5=−3
x=-3

is -4 diapers (mark as brainliest)
Directions: Find each missing measure. please help me find T and U
Answer:
m∠U = 54°
m∠T = 72°
Step-by-step explanation:
The triangle shown is an isosceles triangle. Therefore, the 2 sides and angles that are marked must be congruent:
m∠S = m∠U
m∠S = 54°
m∠U = 54°
All angles in a triangle add up to 180°:
m∠S + m∠U + m∠T = 180°
54° + 54° + m∠T = 180°
108° + m∠T = 180°
m∠T = 72°

A taxi charges an additional fee of 1.50 plus 2.00
Answer:
3.50
Step-by-step explanation:
Assuming you wanted to add 1.50 plus 2.00
This can be done by writing down 1.50 on top of 2.00.
An easier route would be by looking at the "1" in 1.50 and the "2" in 2.00. These are the superior numbers in 1.50 and 2.00.
1+2 is obviously 3. We would add 1/2 to that because 0.50=1/2. Therefore the answer is 3.50

given M is the midpoint of RS . RM=x+3 and MS=2x-1 . x=? and RM= ?
Answers:
x = 4
RM = 7
======================================================
Explanation:
The midpoint cuts the larger segment RS in two equal halves, so RM = MS
RM = MS
x+3 = 2x-1
3+1 = 2x-x
4 = x
x = 4
RM = x+3
RM = 4+3
RM = 7
MS = 2x-1
MS = 2*4-1
MS = 7
Both RM and MS are 7 units long, which confirms our answers.
RS = RM+MS
RS = 7+7
RS = 14

5(p - 3) = 63
Who ever get this right Cash app 300 dollars to u
Answer:
p = 78/5
Step-by-step explanation:
Solve for p:
5 (p - 3) = 63
Divide both sides of 5 (p - 3) = 63 by 5:
(5 (p - 3))/5 = 63/5
5/5 = 1:
p - 3 = 63/5
Add 3 to both sides:
p + (3 - 3) = 63/5 + 3
3 - 3 = 0:
p = 63/5 + 3
Put 63/5 + 3 over the common denominator 5. 63/5 + 3 = 63/5 + (5×3)/5:
p = 63/5 + (5×3)/5
5×3 = 15:
p = 63/5 + 15/5
63/5 + 15/5 = (63 + 15)/5:
p = (63 + 15)/5
63 + 15 = 78:
Answer: p = 78/5

A parking meter at a parking garage charges $4 per hour. Every fraction of an hour is rounded up to the next hour. What is the cost for parking a car in the parking garage for 312 hours
Answer:
$1,248.00, or 1,248 dollars.
Step-by-step explanation:
First, multiply 4, which is the dollars per hour, by 2, which is 8. Then, multiply four with ten, which is 40. Next, multiply 4 with 3, which is 12, and add two zeros on the back, which is 1,200. Finally, add them all together for a total of $1,248.00, or 1,248 dollars.
