How many solutions does this system
have?
x + 2y = 10
2x + 8y
8y = 16
A. None
B. One
C. Infinite

Answer:

-19x

Step-by-step explanation:

so you start with -8 and when you subtract 11 from -8 its the same as adding them but because your subtracting you'll decrease which make the answer -19x. (hopefully this made sense)

Answer:

308 = 18*b

Step-by-step explanation:

The area of a rectangle is given by

A =b*h

We know the area is 308 and the height is 18

308 = 18*b

Answer:

A

Step-by-step explanation:

The base is the circle.

To find the area of the circle, use pi*r^2

pi = 3.14

r = 6

Answer:

C. 414.48

Step-by-step explanation:

1/3 x 3.14 x 6² x 11 = 4.14.48

Answer:

Step-by-step explanation:

y = 6x + 2     ⇒    6x - y = -2

y = 6x - 4      ⇒    6x - y = 4

a₁ = a₂ = 6  ,  b₁ = b₂ = -1 ,  c₁ = -2 , c₂ = 4

a₁ = a₂ = 6   and  b₁ = b₂ = -1  and  c₁ ≠ c₂  ⇒  NO SOLUTIONS

Answer:

A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables. If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative.

Answer:

#7 I think is A

Step-by-step explanation:

Answer:

1) option b ---> (-3, -5)

2) option a ---> (8, 6)

3) option a ---> (5, 8)

Step-by-step explanation:

1) (3, -5) reflection over the y-axis.

According to the rule of reflection over the y-axis :-

(x, y) ---> (-x, y)

(3, -5) ---> (-3, -5)

2) (-6, 8) rotate 90⁰ clockwise.

According to the rule of rotating 90⁰ clockwise :-

(x, y) ---> (y, -x)

(-6, 8) ---> (8, 6)

*Since x was a negative it becomes positive.*

3) (7, 4) translate 2 unit left and 4 units up.

According to the rule of translation :-

(x, y) ---> (x - 2, y + 4)

(7, 4) ---> ( 7 - 2, 4 + 4)

(7, 4) ---> (5, 8)

Answer:

[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{10^{t^{2}}}{100^{t}}[/tex].

[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex].

[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex].

Step-by-step explanation:

The expression to be evaluated is [tex]100^{t^{2}-0.5\cdot t}[/tex], we find by algebraic means the equivalent expression:

Possibility 1:

[tex]100^{t^{2}-0.5\cdot t}[/tex]

[tex]\frac{100^{t^{2}}}{100^{0.5\cdot t}}[/tex]

[tex]\frac{100^{t^{2}}}{(100^{0.5})^{t}}[/tex]

[tex]\frac{100^{t^{2}}}{10^{t}}[/tex]

[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{10^{t^{2}}}{100^{t}}[/tex].

Possibility 2:

[tex]100^{t^{2}-0.5\cdot t}[/tex]

[tex]\frac{100^{t^{2}}}{100^{0.5\cdot t}}[/tex]

[tex]\frac{(50\cdot 2)^{t^{2}}}{(25\cdot 4)^{0.5\cdot t}}[/tex]

[tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex]

[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex].

Possibility 3:

[tex]100^{t^{2}-0.5\cdot t}[/tex]

[tex]\left(\frac{500}{5} \right)^{t^{2}-0.5\cdot t}[/tex]

[tex]\frac{500^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex]

[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex].

Answer:

The bear population after t years will be:

p(t) = 380,000*(1 + 0.025)^t

Step-by-step explanation:

Here the question is missing, so i will found an equation that can tell us the bear population as a function of the number of years that have passed since 2015, represented with the variable t.

The initial bear population in Canada was 380,000.

Each year the population increases by a 2.5%

Then after one year, the population is:

p(1) = 380,000 + 380,000*(2.5%/100%)

p(1) = 380,000 + 380,000*(0.025) = 380,000*(1 + 0.025)

After another year the population increases by 2.5% again, then the new population will be:

p(2) = 380,000*(1 + 0.025) +  380,000*(1 + 0.025)*(2.5%/100%)

p(2) =  380,000*(1 + 0.025) +  380,000*(1 + 0.025)*(0.025)

p(2) = 380,000*(1 + 0.025)*(1 + 0.025)

p(2) = 380,000*(1 + 0.025)^2

So we already can see the pattern here, the bear population after t years will be:

p(t) = 380,000*(1 + 0.025)^t

Step-by-step explanation:

Answer:

[tex]\boxed {\boxed {\sf B. \ \frac{8}{13} }}[/tex]

Step-by-step explanation:

Probability is found by dividing the number of favorable outcomes by the total number of outcomes.

[tex]P= \frac{favorable \ outcomes}{total \ outcomes}[/tex]

For this problem, the favorable outcome is selecting a blue or green marble. There are 8 outcomes for this because there are 6 outcomes for blue and 2 fr green.

The total outcomes are all the marbles. Each marble could be an outcome, so there are 13 outcomes (1 for each marble).

[tex]P(blue \ or \ green) = \frac{8}{13}[/tex]

This fraction cannot be reduced, so the probability of selecting a blue or green marble is 8/13.

Answer:

m<PSR = 60°

Step-by-step explanation:

Given:

m<OPQ = 50°

m<ORQ = 70°

Required:

m<PSR

Solution:

m<PQR + m<OPQ + m<ORQ = 180° (Sum of triangle)

m<PQR + 50 + 70 = 180 (Substitution)

m<PQR + 120 = 180

m<PQR = 180 - 120

m<PQR = 60°

One of the properties of a kite states that the angles where the unequal sides meets are congruent to each other. Therefore:

m<PSR = m<PQR

m<PSR = 60° (substitution)

Answer:

42°

Step-by-step explanation:

4x + 2x + 18 = 90        because they are complementary angles (add up to 90°)

reduce:

6x = 72

x = 12

one angle = 4(12) = 48°

other angle = 2(12) +18 = 42°

https://www.you.tube.com/watch?v=32gDF10ZXOA

( it might be wrong pls dont report me just let me kno y its wrong )

Answer:

8.6

Step-by-step explanation:

First of all consider the thousands in the decimal which is 2. Since 2 is not greater than 5 we have to remove the number 2 and 3 from the 8.6023.

We're left with 8.60. Now we see that there's a 0 in the hundredths so since it's not greater than 5 we remove it.

Now we're left with 8.6 which is to the nearest tenth.

Answer:

$79.670.

Step-by-step explanation:

Dado que María tiene en su libreta de ahorros un capital de $ 123.000,si deposita el día lunes la cantidad de $12.670, y el día miércoles por una urgencia, realiza un giro de $56.000, para determinar cuál es el nuevo capital que posee se debe realizar el siguiente cálculo:

123.000 + 12.670 - 56.000 = X

135.670 - 56.000 = X

79.670 = X

Así, el nuevo capital que María posee en su cuenta es de $79.670.
