Answer:

[tex]x=\dfrac{1}{5}, \quad y=6[/tex]

Step-by-step explanation:

Given equations:

[tex]\begin{cases}y=10x+4\\2y+5x=13\end{cases}[/tex]

To solve the given equations by substitution, substitute the first equation into the second equation and solve for x:

[tex]\begin{aligned}\textsf{Equation 2}: \quad 2y+5x&=13\\\\y=10x+4 \implies 2(10x+4)+5x&=13\\20x+8+5x&=13\\25x+8&=13\\25x+8-8&=13-8\\25x&=5\\\dfrac{25x}{25}&=\dfrac{5}{25}\\x&=\dfrac{1}{5}\end{aligned}[/tex]

Substitute the found value of x into the first equation and solve for y:

[tex]\begin{aligned}\textsf{Equation 1}: \quad y &=10x+4\\\\x=\dfrac{1}{5} \implies y&=10\left(\dfrac{1}{5}\right)+4\\y&=\dfrac{10}{5}+4\\y&=2+4\\y&=6\end{aligned}[/tex]

Therefore, the solution to the equations is:

[tex]x=\dfrac{1}{5}, \quad y=6[/tex]

raina runs 6 miles in 55 minutes

so it speed is 6/55 miles per minute

that means in one minute he runs 6/55 miles

so in 44 minutes

in 44 minutes he will run 24/5 miles or 4.8 miles

FOR THE FURST QUESTION.

[tex] {27}^{ \frac{1}{2} } \\ = (3^{3} )^{ \frac{1}{2} } \\ = {3}^{3 \times \frac{1}{2} } \\ = 3^{ \frac{3}{2} } [/tex]

FOR THE SECOND QUESTION

[tex] \sqrt{2} \\ = ( \sqrt[3]{8} )^{ \frac{1}{2} } \\ = ( {8}^{ \frac{1}{3} } )^{ \frac{1}{2} } \\ = 8^{ \frac{1}{3} \times \frac{1}{2} } ) \\ = 8^{ \frac{1}{6} } [/tex]

FOR THE THIRD ONE

[tex] \frac{ \sqrt{2} }{16} \\ = \frac{ \sqrt{2} }{16} \\ = \frac{ {2}^{ \frac{1}{2} } }{ {2}^{4} } \\ = 2^{ \frac{1}{2} - 4 } \\ = 2^{ - \frac{7}{2} } [/tex]

For the given values of x and y, the value of y/x (that represents the slope of the equation) = 3/1, 3/1, 3

A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

The ratio of the increase in elevation between two points to the run in elevation between those same two points is referred to as the slope.

Given are the values of the x and y

y/x represents the slope of the equation,

for x = -1 and y = -3,

y/x = 3/1

for x = 1 and y = 3

y/x = 3/1

for x = 2 and y = 6

y/x = 6/2 = 3

The length of the tape is 3 and it is divided into equal parts or groups. The length of each group is 1/4. This means that the number of groups in 3(the tape) would be

3÷1/4

We can hold 3 and flip the fraction, 1/4. If we flip 1/4, it becomes 4/1 and the division sign becomes multiplication. The expression would be

3 x 4/1 = 12

The correct option is A

Given the following question:

The family spends 90 dollars at a grocery store each week

The family spends 40 dollars each time they go out to eat.

Part one:

If the family goes out to eat four times they would have spent 250 dollars.

Part two:

The final point on the graph is (6, 330)

Which means if the family goes out six times, the budget is 330 dollars.

So, your answer is 6.

The graph is shifted right to 3 units, then the graph has a horizontal stretch by a factor of 2 and the graph is shifted up 4 units.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The function is:

f(x) = x²

First transformation:

x → (x- 3)

The graph is shifted right to 3 units.

F(x) = (x- 3)²

Second transformation:

F(x) → 2F(x)

The graph has a horizontal stretch by a factor of 2.

h(x) = 2(x- 3)²

Third transformation:

h(x) → h(x) + 4

The graph is shifted up 4 units.

g(x) = 2(x- 3)² + 4

Thus, the graph is shifted right to 3 units, then the graph has a horizontal stretch by a factor of 2 and the graph is shifted up 4 units.

A rational number is a number that can be expressed as a ratio of two integers. Integers can be positive or negative. Rational numbers are simply fractions. For example;

-5/2, -1/5, 3/1, 4/5 etc are all rational numbers because we can write them as a ratio of two integers.

Since some of this fractions can lead to both negativa and positive integers, hence rational number is a positive or negative whole number including 0.

Hence all the options are correct since rational numbers are are also repeating decimals

By using the secant line formula, the average rate of change of function f(x) on the interval [3, 11] is equal to 4.

In accordance with the statement, we must determine the average rate of change for a given closed interval of the function f(x). Graphically speaking, the average rate of change for this interval is represented by the slope of the secant line passing through the two limits of the interval [a, b], which is found by secant line formula:

m = [f(b) - f(a)] / (b - a)

If we know that a = 3, f(a) = 19, b = 11 and f(b) = 51, then the average rate of change is:

m = (51 - 19) / (11 - 3)

m = 32 / 8

m = 4

Benji's total score is -2.

If two numbers are negative, their sum will also be negative. When two negative numbers are added together, their value is further diminished, hence the sum of the two negative numbers is always negative.

Given:

Benji has four -0.5 cards.

According to the question, we have to determine his total score which will be equal to adding scores on all four cards.

As we are adding negative scores, upon adding them place a negative sign in front of the sum.

The total score of Benji = (-0.5) + (-0.5) + (-0.5) + (-0.5)

                                        = -2

Therefore, his total score is -2.

The time that the tank began leaking water is 12:40am

The time the tank will be empty is  11 : 23 pm.

The function that would determine the amount of water in the tank is a linear function. A linear function is a function that has a single power that is raised to the power of one. When drawn on a graph, a linear function is a straight line.

The first step is to determine the rate of leakage of the tank.

Rate = (water in the tank at 11am - water in the tank at 8:30am) / change in time

(137 - 115) / (11 - 8:30)

22 / 2:30

22 ÷ 2 1/2 hours = 8.8 gallons per hour

Linear function would have this form:

Water in the tank = water in the tank when full - (rate of leakage x number of hours)

137 = 200 - (8.8xh)

137 = 200 - 8.8h

200 - 137 = 8.8h

63 = 8.8h

h = 63 / 8.8

h = 7.16 hours = 7 4/15 hours

8 -  7 4/15 hours = 12 10/15 hours = 12.40am

When the tank is empty:

0 = 200 - 8.8h

200 - 0 = 8.8h

200 / 8.8 = 22.72 = 22 hours 43 minutes

22 hours 43 minutes + 12 : 40M = 11 : 23 pm
