BE||CD. Find the value of x and AC.
Answer:
x = 4.8
AC = 16.8
Step-by-step explanation:
From the picture attached,
In ΔABE and ΔACD
BE║CD, and the AC and AD are the transversal lines.
∠ABE ≅ ∠ACD [Corresponding angles]
∠AEB ≅ ∠ADC [Corresponding angles]
ΔABE ~ ΔACD [By AA property of similarity of two triangles]
And by the property of similar triangles, corresponding sides of the similar triangles are always proportional.
[tex]\frac{\text{AC}}{\text{AB}}=\frac{\text{AD}}{\text{AE}}[/tex]
[tex]\frac{x+12}{12}=\frac{10+4}{10}[/tex]
[tex]\frac{x+12}{12}=\frac{14}{10}[/tex]
10(x + 12) = 12 × 14
10x + 120 = 168
10x = 168 - 120
x = 4.8
AC = x + 4.8
= 12 + 4.8
= 16.8

Write your Geometry Statement.
If PQ = 6x - 1 and PR = 15x - 29,
then QR = ?
Answer:
QR = 21x - 30
Step-by-step explanation:
Iff Q - P - R,
Then
QR = PQ + PR
QR = 6x - 1 + 15x - 29
QR = 21x - 30

Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher? Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher?
Answer:
2.125 liters of juice
Step-by-step explanation:
Total liters of juice = 9
Total liters left = 0.5
Total liters used = Total liters of juice - Total liters left
= 9 - 0.5
= 8.5
Total liters used = 8.5 liters
He pours equal amounts of the juice into 4 pitcher
Liters per pitcher = Total liters used / number of pitchers
= 8.5 / 4
= 2.125 liters
Liters per pitcher = 2.125 liters
Each pitcher has 2.125 liters of juice
Write an equation in slope-intercept form of the line with the given slope (m) and y-intercept (b). m= 1 b= -1
Answer:
y = 1x - 1 is the slope-intercept form
Answer:
y=1x-1
Step-by-step explanation:
Slope Intercept Form is y=mx+b where m is the slope, x is the number of x times, b is the y intercept, y intercept is the part of a line where the x is 0 and the y touches a y axis, vice versa for x intercept

What is the value of x?
-5x – 2 = -13
Answer:
2.20
Step-by-step explanation:
So add +2 both sides that cancels 2 and that makes it -11.00 now divide it by -5 and x is by itself
So when you divide it x=2.20
Hope that helps
Can someone please help
please help o need to know the slope!
Answer:
A
Step-by-step explanation:
100% slope is -3 because you need to move down 3 times which is -3 and move to the right once which is 1
Slope= rise/run
Slope=-3/1 which equals -3
y-intercept= 2 because you just look at the y-axis and see any points that connects to it while the x is zero

What is the solution to the following problem??
y=35x
Answer:
Infinite solutions
Answer:hope u understand it better
Step-by-step explanation: y=3
We simplify the equation to the form, which is simple to understand
y=3
We move all terms containing y to the left and all other terms to the right.
+1y=+3
We simplify left and right side of the equation.
+1y=+3
We divide both sides of the equation by 1 to get y.
y=3
on the number line below. P number what is the value of the opposite of that number.
Answer: -1 2/4 is the opposite of 1 2/4
Step-by-step explanation: On the number line the P represents 1 2/4, so the opposite of that is -1 2/4.

What is the measure of <8
Answer:
C. 39
Step-by-step explanation:
m∠3 ≅ m∠5
4x - 7 = 6x - 81
-7 = 2x - 81
74 = 2x
37 = x
m∠5 = 6(37) - 81 = 141
m∠8 = 180 - 141 = 39
Solve for r. 60 = -24 + 12r
Answer:
r = 7
Step-by-step explanation:
60 = -24 + 12r
+24 +24
84 = 12r
84 ÷ 12 = r
7 = r
Check:
60 = -24 + 12r
-24 + 12(7)
-24 + 84 = 60

15-2(7 - x) = 7
(Multi- step equations)
show steps please:)<4
Answer:
3
Step-by-step explanation:
15 - 2(7 - x) = 7
collect like terms
-2(7 - x) = 7 - 15
-2(7 - x) = -8
divide both sides by -2
7 - x = -8/-2
7 - x = 4
collect like terns
-x = 4 - 7
-x = -3
dividing both sides by -
x = 3
Answer:
Step-by-step explanation:
15-2(7-x)=7
15-14+2x=7
1+2x=7
2x=6
x=3

Answer:
a[n] = n² +2n +9
Step-by-step explanation:
First differences are ...
17-12 = 5; 24-17 = 7; 33-24 = 9 . . . . . . define d1=5
So, second differences are ...
7-5 = 2; 9-7 = 2 . . . . . . . define d2=2
The coefficient of the n² term is half the second difference (=d2/2). The 0-th term will be smaller than the first term by the difference between the first first difference and the second difference (d1-d2):
a0 = a1 -(d1 -d2) = 12 -5 +2 = 9
So, the quadratic rule will be ...
a[n] = n² +9 +kn
for some value of k.
We can find k using the first term of the sequence.
a[1] = 1² +9 +k·1 = 12
k = 12 -10 = 2
Then the rule is ...
a[n] = n² +2n +9
