y - 4 = -2 ( x - ( -11)) which would simplify to y - 4 = -2 ( x + 11) !!
Does anyone know how to do this?
Answer:
1)X+4=2x-17+10
X. =2x-7-4
11=X
DF=11+4
=15
2)FH~
11x+71=12x+32
12x-11x =71-32
X=39
FH=(11×39)+71+(12×39)+32
=1000
3)57+39+8x-12=180
8x+84-84=180-84
8x=96
X=12
4)11x+2=68
11x=66
X=6
5)114+X+37+X=139
2x+151. -151=139-151
X=-6
Answer:
1. x=11
2. x=39
3. x= 12
4. x=6
5. x=-6
Step-by-step explanation:
1. x+4= 10+2x-17
FG=GH
x+4=2x-7
11=x
2. 11x+71=12x+32
subtract from both sides
39=x
3. All angles of a triangle add to 180.
39+57+(8x-12)=180
96+(8x-12)=180
8x-12=84
8x=72
divide both sides by 8
x=9
4. Vertical angles are equal
68=11x+2
66=11x
divide
6=x
5. (114+x)+(37+x)=139
Add like terms
151+2x=139
subtract
2x=-12
x=-6

Step-by-step explanation:
Red marbles, R= 5
White, W = 9
Blue, B = 7
Total = (5 + 9 + 7) = 21
Selecting 3 marbles without replacement :
Probability that all marbles are the same
P(RRR) or P(BBB) or P(WWW)
(5/21 * 4/20 * 3/19) + (7/21 * 6/20 * 5/19) + (9/21 * 8/20 * 7/19)

Fig 1

<D and <E are base angle of isosceles triangle.
Fig 2
AB=AC=BC=8
All the side of equilateral are equal and all interior angle also equal.
Answer:
Step-by-step explanation:
a) ΔFED is isosceles triangle. EF = ED
∠F = ∠D =x {Angles opposite to equal sides are equal}
∠F + ∠E + ∠D = 180 {Angle sum property }
x +x + 30 = 180
2x + 30 = 180
2x = 180 -30
2x = 150
x = 150/2
x = 75
∠F = 75
b) All the angles are equal. So, it is an equilateral triangle. In equilateral triangle all sides are equal.
So, AB = 8

Answer:
Step One: Divide both sides by 2
Step Two: Add 3 to both sides
Step Three: Multiply both sides by 1/6
Step-by-step explanation:
For step one, we can see that half of 12 is 6, half of 6 is 3 and half of 10 is 5.
For step two, we add 3 to the left to cancel out the -3 and add 3 to the left to make 8.
By process of elimination, we can see that C matches up to step 3.

Williiam lost 25% of his marble,gave 1/6 of the remainder to his.Brother and had 120 marbles left.How many marbles did he have at first?
Answer:
Number of marbles with Williams at the starting = 192
Step-by-step explanation:
Let total number of marbles with Williams = m
He lost marbles = 25% of the total number
= [tex]\frac{25}{100}\times m[/tex]
= [tex]\frac{m}{4}[/tex]
Remaining marbles with Williams = m - [tex]\frac{m}{4}[/tex]
= [tex]\frac{3m}{4}[/tex]
He gave marbles to his brother = [tex]\frac{1}{6}[/tex]th of the remaining marbles
= [tex]\frac{1}{6}\times \frac{3m}{4}[/tex]
= [tex]\frac{m}{8}[/tex]
Remaining marbles after giving marbles to his brother = 120
Therefore, [tex]\frac{3m}{4}-\frac{m}{8}=120[/tex]
[tex]\frac{6m}{8}-\frac{m}{8}=120[/tex]
[tex]\frac{5m}{8}=120[/tex]
m = [tex]\frac{120\times 8}{5}[/tex]
m = 192
Number of marbles with Williams at the starting = 192

How do you decide where to shade an inequality whose boundary does not go through the origin?
Answer:
Step-by-step explanation:
basically, you have to look at the inequality. it is the same all around. so if the inequality has less than or equal too, or greater than or equal too, you need to have a thick solid line representing your function. if it is just less than or greater than, use a dotted line. to determine whether the shading goes above or below, you look at the in equality. greater than is above, and less than is below

Suppose that a plano cost 5,000 and loses 20% of its value oach year. table shows the value, of a piano after years.
1. 5000

write an equation that can be used to find the value of the piano, v, after t years.
Answer:
Step-by-step explanation:
90
Based on the information, the value of the piano after 16 years is $140.74.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Using this formula to find the value of the piano, v, after t years.
CP = Principal(1-rate)[tex]^t[/tex]
Where:
Principal=$5,000
Rate=20%
Number of year = 16 years
Let plug in the formula;
=5,000(1-0.20)^16
=5,000(.80)^16
=$140.737
= $140.74 (Approximately)
Hence, the value of the piano after 16 years is; $140.74.

11x - ? = 19x what is the missing number?
Answer:
8x !
Step-by-step explanation:
Answer:
8x
Step-by-step explanation:
What is the solution for the equation, 2(4x – 6) = 8x – 12
Simplifying
2(4x + -6) = 8x + -12
Reorder the terms:
2(-6 + 4x) = 8x + -12
(-6 * 2 + 4x * 2) = 8x + -12
(-12 + 8x) = 8x + -12
Reorder the terms:
-12 + 8x = -12 + 8x
Add '12' to each side of the equation.
-12 + 12 + 8x = -12 + 12 + 8x
Combine like terms: -12 + 12 = 0
0 + 8x = -12 + 12 + 8x
8x = -12 + 12 + 8x
Combine like terms: -12 + 12 = 0
8x = 0 + 8x
8x = 8x
Add '-8x' to each side of the equation.
8x + -8x = 8x + -8x
Combine like terms: 8x + -8x = 0
0 = 8x + -8x
Combine like terms: 8x + -8x = 0
0 = 0
Solving
0 = 0
Answer:
