Answer:
y= -7
Step-by-step explanation:
So first distribute the 8
4=8y+32-4y
now combine like terms (the -4y+8y)
4=32+4y
Subtract 32 on both sides to isolate 4y
-28=4y
now divide 4 on both sides to isolate Y
-7=y
so y= -7
What is the answer for -3p(p+2) - (2p+3) using the distribution method?
Answer: -3p^2-8p-3
Step-by-step explanation: By distributing we get, -3p^2-6p-2p-3. Then simplify accordingly.
To figure out this problem, we need to break down the steps:
-3p(p + 2) - (2p + 3)
because -3p is next to the equation in parentheses, (p + 2), you should multiply -3p into both p and 2
-3p x p = -3p² (if you multiply a variable (p) by another of the same variable with no power, it becomes squared)
-3p x 2 = -6p
so the first part of the equation went from -3p(p + 2) to -3p² -6p
and the second part of the equation has no multiplying to do
so now we add like terms!
-3p² -6p - 2p + 3
-3p² -8p + 3
order from greatest power to least power (first goes the number/variable with the highest power, then the term with a variable, and lastly the number. Right now it is currently in the correct order).
-3p² -8p + 3 is your final answer

Which of the following is the slope intercept form of the equation
3x - 8y = 16
A- y = 3/8x + 2
B- y = 3/8x - 2
C- y = -3/8x + 2
D- y = -3/8x - 2
Answer:
y = 3/8 x - 2
Step-by-step explanation:
Put 8y on the other side to get
8y + 16 = 3x
8y = 3x - 16 and thus
y = 3/8 x - 2

Find the perimeter of the figure. Round to the nearest tenth.
Answer:
perimeter = 20.9 units
Step-by-step explanation:
perimeter
perimeter = distance around two dimensional shape
= addition of all sides lengths
perimeter of the figure= AB+BC+CD+ADdistance formula:
[tex]d = \sqrt{( x_{2} - x_{1}) {}^{2} + ( y_{2} - y_{1}) {}^{2} } [/tex]
1) distance of ABA(-3,0) B(2,4)
x1 = -3 x2 = 2
y1 = 0 y2 = 4
(substitute the values into the distance formula)
[tex]ab = \sqrt{(2 - ( - 3)) {}^{2} + (4 - 0) {}^{2} } [/tex]
[tex]ab = \sqrt{5 {}^{2} + 4 {}^{2} } [/tex]
[tex]ab = \sqrt{41} [/tex]AB = 6.4 units
2) distance of BCB(2,4) C(3,1)
x1 = 2 x2 = 3
y1 = 4 y2 = 1
[tex]bc = \sqrt{(3 - 2) {}^{2} + (1 - 4) {}^{2} } [/tex]
[tex]bc = \sqrt{1 {}^{2} + ( - 3) {}^{2} } [/tex]
[tex]bc = \sqrt{10} [/tex]
BC = 3.2 units
3) distance of CDC(3,1) D(-4,-3)
x1 = 3 x2 = -4
y1 = 1 y2 = -3
[tex]cd = \sqrt{( - 4 - 3) {}^{2} + ( - 3 - 1)) {}^{2} } [/tex]
[tex]cd = \sqrt{( - 7) {}^{2} + ( - 4 ){}^{2} }[/tex]
[tex]cd = \sqrt{65} [/tex]
CD = 8.1 units
4) distance of ADA(-3,0) D(-4,-3)
x1 = -3 x2 = -4
y1 = 0 y2 = -3
[tex]ad = \sqrt{( - 4 - ( - 3)) {}^{2} + ( - 3 - 0) {}^{2} }[/tex]
[tex]ad = \sqrt{( - 1) {}^{2} + ( - 3) {}^{2} } [/tex]
[tex]ad = \sqrt{10} [/tex]
AD = 3.2 units
perimeter of figure= AB+BC+CD+AD
= 6.4 + 3.2 + 8.1 + 3.2
= 20.9 units

Answer:
12
Step-by-step explanation:
4u - 8u = -63 + 15 ( collecting like terms)
-4u = -48
u = 12
Answer:
u = 12
Step-by-step explanation:
4u - 8u - 15 = -63
Step 1: Combine 4u and -8u
-4u - 15 = -63
Step 2: Add 15 to both -15 and -63
-4u = -48
Step 3: Divide both -4u and -48 by -4
u = 12

Two parallel lines are crossed by a transversal. Vertical and parallel lines h and i are cut by transversal g. At the intersection of lines h and g, the uppercase right angle is 70 degrees and the bottom left angle is x degrees. What is the value of x?
Answer:
x = 70°
Step-by-step explanation:
There are two vertical and parallel lines h and i. Also, a transversal line g cuts across these parallel lines. The intersection of the transversal line and line h produces an upper right angle of 70° and bottom left angle of x°.
These angles x and 70 are vertically opposite angles, hence:
x = 70° (vertically opposite angles are equal to each other)
Answer:
70

Two friends are planning a vacation. They are deciding between Arizona and New York. The airfare for Arizona is $95 per person and the airfare for New York is $150 per person. The hotel in New York is $120 per night and the hotel in Arizona is $150 per night. They would share a hotel room. After how many nights would the trip's cost be equal to each other?
Answer:
7
Step-by-step explanation:
Let number of nights spent in both the locations be [tex]x[/tex]
Airfare for Arizona for 2 persons for two way journey = [tex]95\times 4=\$380[/tex]
Airfare for New York for 2 persons for two way journey = [tex]150\times 4=\$600[/tex]
Cost of night spent in Arizona = [tex]150x[/tex]
Cost of night spent in New York = [tex]120x[/tex]
Cost of going and coming back from Arizona = [tex]380+150x[/tex]
Cost of going and coming back from New York = [tex]600+120x[/tex]
Now the costs should be equal so
[tex]380+150x=600+120x\\\Rightarrow 150x-120x=600-380\\\Rightarrow x=\dfrac{220}{30}\\\Rightarrow x=7.33\ \text{nights}[/tex]
The number of nights is approximately 7 at which the cost of the trip becomes equal.

(6 - 1) + (3m)i = -12 + 27i
Answer:
We want to solve the equation:
(6 - 1) + (3m)i = -12 + 27i
Where m is a complex number.
first, we can rewrite this as:
5 + 3*m*i = -12 + 27*i
3*m*i = -12 - 5 + 27*i
3*m*i = -17 + 27*i
And we can write m as:
m = a + b*i
Replacing that in the above equation we get:
3*(a + b*i)*i = -17 + 27*i
3*a*i + 3*b*i^2 = -17 + 27*i
and we know that i^2 = -1
3*a*i - 3*b = -17 + 27*i
The real part in the left (-3*b) must be equal to the real part in the right (-17)
then:
-3*b = -17
b = -17/-3 = 17/3
And the imaginary part in the left (3*a) must be equal to the imaginary part in the right (27)
then:
3*a = 27
a = 27/3.
Then the value of m is:
m = a + b*i = (27/3) + (17/3)*i

Trying to factor by splitting the middle term
2.1 Factoring 2x2+3x+3
The first term is, 2x2 its coefficient is 2.
The middle term is, +3x its coefficient is 3.
The last term, "the constant", is +3
Step-1: Multiply the coefficient of the first term by the constant 2 • 3 = 6
Step-2: Find two factors of 6 whose sum equals the coefficient of the middle term, which is 3.
-6 + -1 = -7
-3 + -2 = -5
-2 + -3 = -5
-1 + -6 = -7
1 + 6 = 7
2 + 3 = 5
3 + 2 = 5
6 + 1 = 7
Observation: No two such factors can be found !!
Conclusion: Trinomial can not be factored
Final result :
2x^2 + 3x + 3

use the following transformations with each question:
Reflection across the x-axis
Reflection across the y-axis
Reflection across the y = x
Reflection across the y = -x
Step-by-step explanation:
Given A(1 , -3)
Reflection across the x -axis
= A'( 1 , 3)
Reflection across the y-axis
= A'( -1 , - 3)
Reflection across the y = x
= A' ( -3 , 1)
Reflection across the y = - x
=A'( 3 , - 1)

Mrs. Cherry earns an 3% commission on homes she sells. A buyer has agreed to buy a home for 94% of its original selling price. The
original selling price of the house is $275,000. How much commission will Mrs. Cherry earn on this sale ?
Answer:
a commission of $7755
Step-by-step explanation:
original price = $275,000 x 0.94 = $258,500
258500 x 0.03 = $7755
Answer:
$7,755
Step-by-step explanation:
94% of $275,000 is $258,500
3% commission off that would be $7,755

A doghouse is to be built in the shape of a right trapezoid, as shown below. What is the area of the doghouse?
A right trapezoid with top side 7 feet and height 7 feet. The bottom side is extended to the right with 3 more feet.
24.5 square feet
59.5 square feet
70 square feet
147 square feet
Answer:
70 square feet
Step-by-step explanation:
This is because the correct formula for this problem is: base x height
Using this formula, you first have to find the base of the trapezoid. Since the square's base is 7 ft, and the triangle's base is 3 ft, you add these together and get 10 ft as a base. For the height, you need the square's height which is 7 ft. Then you multiply and get 70 ft.
