Answer:
3^x + 10x+2x-4
Step-by-step explanation:
f(x) = 3^x + 10x and g(x) = 2x - 4
(f + g)(x)= 3^x + 10x+2x-4
Answer:
(f + g) x = 3 ^x + 10 x + 2 x - 4
Step-by-step explanation:
f (x) = 3^x + 10 x and g(x) = 2x - 4,
sum of f (x ) and g ( x ) =
(f + g) x = 3 ^x + 10 x + 2 x - 4
which expression is equivalent to 4(3x+2)-5x
A = 7x+2
B = 7x+8
C+12x+2
D=2x+8
Answer:
B) 7x + 8
Step-by-step explanation:
distribute 4 first to get:
12x + 8 - 5x
combine like terms to get:
7x + 8
Decide whether there is enough information to prove that △WXZ≅△YZX using the SAS Congruence Theorem.
A: yes; Because ZW≅XY, ∠W≅∠Y, and WX≅YZ, the two triangles are congruent by the SAS Congruence Theorem
B: yes; Because ZW≅XY, ∠W≅∠Y, and ZX≅XZ, the two triangles are congruent by the SAS Congruence Theorem.
C: no; There is one pair of congruent sides and one pair of congruent angles, but there is no other pair of congruent sides.
D: no; There are two pairs of congruent sides and one pair of congruent angles, but the angles are not the included angles.
Answer:
D
Step-by-step explanation:
ΔWXZ and ΔYZX
WZ ≅XY {Given}
ZX ≅ ZX {Reflexive property}
∠W ≅ ∠Y
But for SAS congruent the congruent angles should between congruent sides( WX & WZ should be congruent to ZY & XY respectively).
So it cannot be proved using SAS congruent
DOÑA JUANA TIENE CULTIVADO LO SIGUIENTE: 80 hm2 DE NARANJAS, 300 Dam2 DE MANDARINAS, 700000 dm2 DE LIMONES Y 8200000 cm2 DE TORONJAS. ¿CUANTAS HECTAREAS EN TOTAL TIENE CULTIVADAS?
Answer:
Doña Juana tiene 83,782 hectáreas cultivadas en total.
Step-by-step explanation:
Dado que Doña Juana tiene cultivadas 80 hectómetros cuadrados de naranjas, 300 decámetros cuadrados de mandarinas, 700000 decímetros cuadrados de limones y 8200000 centímetros cuadrados de toronjas, para determinar cuántas hectáreas en total tiene cultivadas se deben realizar los siguientes cálculos:
1 Hm2 = 1 hectárea x 80 = 80 hectáreas
1 Dam2 = 0.01 hectárea x 300 = 3 hectáreas
1 Dm2 = 0.000001 hectárea x 700000 = 0.7 hectáreas
1 Cm2 = 0.00000001 hectárea x 8200000 = 0.082 hectáreas
80 + 3 + 0.7 + 0.082 = X
83,782 = X
Por lo tanto, Doña Juana tiene 83,782 hectáreas cultivadas en total.

Simplify (-4a^5b) (2a^2b)
Answer:
[tex]-8a^{7b}[/tex]
Step-by-step explanation:
[tex](-4 a^{5b}) (2a^{2b}) = -(2^2 a^{5b}) (2a^{2b})\\[/tex]
[tex]= -(2 ^2 \times 2) \times a^{5b + 2b}\\\\= -(2 ^{2+1}) \times a^{7b}\\\\=-(2^{3}) \times a^{7b}\\\\= - 8 a^{7b}[/tex]
A T.V. is regularly priced at $600, but it is on sale for 20% off. What's the sale price?
Answer:
$480
Step-by-step explanation:
multiply the normal price $600 by 20 then divide it by one hundred
the discount is $120
the sales price is subracting the discount of $120 from the original price of $600 then get $480 as the sales price.
Answer:
Step-by-step explanation:
Method 1: Subtract 20% from 100%, obtaining 80%, and then multiply the regular price ($600) by the decimal equivalent 0.80. We get $480 as the sale price.
Method 2: Calculate the amount of the discount by multiplying $600 by 0.20, obtaining $120. Then subtract this discount from the regular price, $600, obtaining $480.
2w+2019 = 15w + 1838
Answer:
181/13 =w
Step-by-step explanation:
2w+2019 = 15w + 1838
Subtract 2w from each side
2w-2w+2019 = 15w-2w + 1838
2019 = 13w + 1838
Subtract 1838 from each side
2019 -1838 = 13w
181 = 13w
Divide each side by 13w
181/13 = 13w/13
181/13 =w

Jacinta received a scholarship from the american meteorological society and was able to pay 43% of one year of her college with the scholarship money the remainder 11, 033.75 for the year was posted for with a student loan what was the total cost of 4 years
Answer:
$77429.824
Step-by-step explanation:
Let the total college cost for one year = x
43% of x was paid with scholarship fee
Percentage left = 100% - 43% = 57%
57% is equivalent to 11,033.75
57/100x= 11,033.75
0.57x = 11033.75
x = 11033.75 / 0.57
x =19357.456 ; this is Jacinta's college fee for a year ;
Hence
College fee for 4 years :
19357.456 * 4 = $77429.824
11. The length of a rectangle is decreased by 25%
and the width is increased by 40%. Calculate

to. find.
area of the rectangle
given
decreased. 25•/•

solusion
Length = L
Breadth = B
Original area = L x B
New area = A = L x (1 - 25%) x B x (1 + 40%)
A = L x B x 0.75 x 1.40 = L x B x 1.05
Therefore the area of the rectangle has increased by 5%.

Given:
A figure of a rectangular prism with length l, width w and height h.
To find:
The surface area of the rectangular prism.
Solution:
The product of twice of the length l and the width w is:
[tex]2\times l\times w=2lw[/tex] ...(i)
The product of twice of the length l and the height is:
[tex]2\times l\times h=2lh[/tex] ...(ii)
The product of twice of the width w and the height h is:
[tex]2\times w\times h=2wh[/tex] ...(iii)
The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:
[tex]A=2lw+2lh+2wh[/tex]
[tex]A=2(lw+lh+wh)[/tex]
Therefore, the required expression is [tex]2(lw+lh+wh)[/tex].
Min had some cards He gave half of the cards to Bill. Bill give 1/3 of those cards to Sam. Sam gave 2 cads back to Min and Kept 6. How many cards did Min have in the end?
Answer: 26 cards
Step-by-step explanation:
Suppose there are x cards initially
Min gave half to bill i.e. 0.5x
Bill gives one-third of those cards to Sam i.e. [tex]\frac{1}{3}\times 0.5x[/tex]
Sam gave 2 cards back to min and kept 6 i.e. Sam gets 8 cards from Bill
[tex]\Rightarrow 8=\dfrac{1}{3}\times 0.5x\\\\\Rightarrow 0.5x=24\\\Rightarrow x=48[/tex]
So, min has 0.5x+2 cards i.e.
[tex]\Rightarrow 0.5\times 48+2\\\Rightarrow 26\ \text{cards}[/tex]

Step-by-step explanation:
As far as I can tell, all the correct examples are
1) Symmetrical
2) Have a line splitting them symmetrically and does not go above or below the shape (Does that make sense?)
The wrong examples don't have any of the characteristics told above. For example, the square would be wrong because it doesn't even have a line

Answer:
x = 7
Step-by-step explanation:
The sum of both angles are complementary that is;
6x + 48 = 90
6x = 90 - 48
6x = 42
x = 42/6
x = 7
Hence the value of x is 7

Solve the system of equations.
3x – 7y = 5
9y = 5x + 5
how do i solve this
Answer:
A = 61
Step-by-step explanation:
Complementary angles add to 90 degrees
A+B = 90
A +29 = 90
A = 90-29
A = 61
Answer:
∠A = 61°
Step-by-step explanation:
We know that sum of both angles of complementary angle is 90°.
∠A + ∠B = 90°
∠A + 29° = 90° ... (∠B = 29° - given )
subtract 29° from each side
∠A + 29° - 29° = 90° - 29°
∠A = 61°

Complete question is;
Craig went to an auction and bought five different items. Use the clues below to determine the price he paid for each item.
1. the chair was the most expensive item, which sold for $95.
2. The range of the prices of the five items was $75.
3. The stereo was the least expensive item.
4. Craig bought the TV for $25.
5. The video game player was $20 more than the TV.
6. The bed was $60 more than the stereo.
Answer:
Cost of chair = $95
Cost of stereo = $20
Cost of TV = $25
Cost of video game player = $45
Cost of bed = $80
Step-by-step explanation:
We are told the chair was the most expensive item which was $95.
the range of the prices of the five items was $75. This means;
Highest price - lowest price = $75
Since highest price is $95, then lowest price = 95 - 75 = $20
stereo is the least expensive item. Thus, stereo will cost $20.
TV was bought for $25
video game player was $20 more than the TV. Thus, video game player cost = 25 + 20 = $45
Bed was $60 more than stereo. Thus,
Cost of bed = $20 + $60 = $80

Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and
we can change 9⁻¹ to 9¹ by moving it to the numerator.
So we have 9¹/4¹ which simplifies to 9/4.
Four friends raised a total of $730 for a local charity. Each friend raised the same amount of money. Model the total amount that the friends raised using the least number of base-ten blocks possible.
Answer:
Each friend raised $ 182.50.
Step-by-step explanation:
Given that four friends raised a total of $ 730 for a local charity, and each friend raised the same amount of money, for model the total amount that the friends raised the following calculation must be performed:
730/4 = X
182.5 = X
Therefore, each friend raised $ 182.50.
