Select the correct answer. The temperature in Bloomington on Sunday was 32.6°C. On Monday, the temperature changed by -8.25°C. What was the temperature on Monday?

Answer:

Step-by-step explanation:

set it up like this

19x + 11 = 11x + 4

then self like algebra

19x + 11 -4 = 11x + 4 - 4

19x + 7 = 11x

19x -11x + 7= 11x -11x

8x ÷ 8 + 7 ÷ 8

x = 0.875

plug it into

19x + 11

19 × 0.875 + 11 = 27.625

so 27.625  should be your answer

The graph of the equation is the set of all points that are solutions to the equation.

The point (1, 1) is on the graph of the equation.

The point (0, −3) is on the graph of the equation.

Step-by-step explanation:

The statements that are true about the linear equation are:

The graph of a linear equation is a line. The line is made up of all points that satisfy the equation. To find the points that satisfy the equation, we can substitute different values for x and solve for y.

If we substitute x=1, we get y=4(1)−3=1. So, the point (1, 1) is on the graph of the equation.

If we substitute x=0, we get y=4(0)−3=−3. So, the point (0, −3) is also on the graph of the equation.

The graph of the equation is a line that passes through the points (1, 1) and (0, −3).

-9 x -3

Step-by-step explanation:

-7 x -2 will give +14.

-9 x -3 will give +27

+27 is greater than +14.

Two negative numbers multiplied will give a positive answer. (Always)

Multiplying two negative numbers gives a positive product. Therefore, both (-9)*(-3) and (-7)*(-2) result in positive numbers. However, (-9)*(-3) equals to 27, which is greater than (-7)*(-2) equals to 14.

In Mathematics, when you multiply two negative numbers together, the product is a positive number. This is because the rules of sign in multiplication state that a negative times negative equals to a positive. Therefore, both (-9)*(-3) and (-7)*(-2) will result in positive numbers. (-9)*(-3) equals 27, while (-7)*(-2) equals 14. So, the product of (-9)*(-3), which is 27, is greater than the product of (-7)*(-2), which is 14.

To determine which table allows more square arrangements, we find the square root of the total number of items on each table. As the square root of 180 (number of cookies) is larger than the square root of 150 (number of cupcakes), the table with the cookies allows more square arrangements.

To determine which table allows more square arrangements, we need to find the square root of the total number of mini cupcakes and mini cookies on each table. This is because a square arrangement means that the number of items along the length and the width are the same, which is the definition of a square root.

For the cupcakes, the square root of 150 is approximately 12.25, which means you can't form a perfect square arrangement as you can't have a fraction of a cupcake. So, you can arrange 12 cupcakes in a row and a column to form a nearly square array with 144 cupcakes, and there would be 6 cupcakes left over.

For the cookies, the square root of 180 is approximately 13.42. So, you can arrange 13 cookies in a row and a column to form a nearly square array with 169 cookies, and there would be 11 cookies left over.

Therefore, the table with cookies allows more square arrangements than the one with cupcakes.

Answer:

[tex]x \sqrt{1-9x^2} -3x \sqrt{1-x^2}[/tex]

Step-by-step explanation:

Since we have to analyze the cosine of an addition of angles, let's recall that cos of an addition is:

[tex]cos (\alpha +\beta ) = cos(\alpha ) cos(\beta) - sin(\alpha) sin(\beta)[/tex]

Let's also use those Greek letters [tex]\alpha[/tex] and [tex]\alpha[/tex] to represent the inverse functions we are dealing with:

[tex]\alpha =arcsin(3x)[/tex] and therefore, [tex]sin(\alpha ) = 3x[/tex]

[tex]\beta =arccos(x)[/tex] and therefore [tex]cos(\beta ) = x[/tex]

Now use these identities to re-write the equation for the cos of an addition given above:

[tex]cos (\alpha +\beta ) = cos(\alpha ) cos(\beta) - sin(\alpha) sin(\beta)\\cos (\alpha +\beta ) = cos(\alpha ) x - 3x sin(\beta )[/tex]

Now recall that the sine of an angle can be written in terms of the cos of the same angle via the Pythagorean identity: [tex]sin(\beta ) = \sqrt{1-cos^2(\beta) }[/tex]

In our case, and with our particular values, this gives:

[tex]sin(\beta ) = \sqrt{1-cos^2(\beta)} = \sqrt{1-x^2}[/tex]

Similarly we can write the cos of an angle in terms of the sine of the same angle:

[tex]cos(\alpha ) = \sqrt{1-sin^2(\alpha) }[/tex]

In ours case, using our values, this gives:

[tex]cos(\alpha ) = \sqrt{1-sin^2(\alpha) }= \sqrt{1-(3x)^2}= \sqrt{1-9x^2}[/tex]

So replacing these in the cos of an addition of angles formula, we obtain that the given expression equals:

[tex]x \sqrt{1-9x^2} -3x \sqrt{1-x^2}[/tex]

We can simplify the expression cos(arcsin(3x) + arccos(x)) in terms of x without trigonometric functions by using sin(arccos(x)) = sqrt(1 - x^2). The simplified expression is sqrt(1 - (3x)^2) * x - 3x * sqrt(1 - x^2).

To simplify the expression cos(arcsin(3x) + arccos(x)) in terms of x without trigonometric functions, we can use the fact that sin(arccos(x)) = sqrt(1 - x^2). Let's start by finding sin(arccos(x)).

arccos(x) gives us an angle whose cosine is x. We can then take the sine of this angle to get sin(arccos(x)). We know that sin^2(arccos(x)) + cos^2(arccos(x)) = 1, so sin(arccos(x)) = sqrt(1 - x^2).

Now, let's substitute the values in the original expression:

cos(arcsin(3x) + arccos(x)) = cos(arcsin(3x)) * cos(arccos(x)) - sin(arcsin(3x)) * sin(arccos(x))

Substituting the values, we have: cos(arcsin(3x)) * cos(arccos(x)) - sin(arcsin(3x)) * sin(arccos(x)) = sqrt(1 - (3x)^2) * x - 3x * sqrt(1 - x^2)

This is the simplified expression of cos(arcsin(3x) + arccos(x)) in terms of x without trigonometric functions.

Answer:

a grapefruit would cost $0.06  and an orange would cost $0.05

Step-by-step explanation:

The price of an orange is 0.5 dollars and price of a grape is 0.6 dollars.

A linear equation has highest degree of a and contains two variables generally in x and y.

According to the given question you bought eight oranges and one grapefruit for a total of 4.60.

Let oranges be denoted by O and grapefruit be denoted by G.

∴ 8O + 1G = 4.60...(i)

Later that day, you bought six oranges and three grapefruits for a total of 4.80.

∴ 6O + 3G = 4.80...(ii)

Now multiplying (i) by 3 and subtracting it from (ii) to cancel out one variable and get the value of the other.

We get O = 0.5 dollars and G = 0.6 dollars.
