60 divided by 3 = g - 8 divided by 2 what does g equal?

The value of x = 3 for y = 9 is a solution of the linear equation -4x = y - 21.

If an equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables.

Examples of two-variable linear equations are 10x+4y = 3 and -x+5y = 2.

Such an equation has a pair of numbers as its solution, one for x and one for y, which further equalises the two sides of the equation.

A specific point on the graph represents the solution of a linear equation in two variables, ax+by = c, where the total of these two values will equal c when the x-coordinate is multiplied by a and the y-coordinate by b.

Basically, there are infinitely many solutions to a linear equation with two variables.

The solution of the equation (x,9).

For the equation -4x = y -21

here, y = 9

-4x = 9 - 21

⇒ -4x = -12

⇒ x = 3.

The boy should throw the ball at a speed of 17.15 m/s.

Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This tendency to resist changes in a state of motion is inertia. If all the external forces cancel each other out, then there is no net force acting on the object.  If there is no net force acting on the object, then the object will maintain a constant velocity. His second law defines a force to be equal to change in momentum (mass times velocity) per change in time. Momentum is defined to be the mass m of an object times its velocity V.

From Newton's equations of motion,

v = u + at

Here, v = 0 m/s

a = g = -9.8 m/s²

t = 3.5/2 = 1.75 s

Put these values in the above equation:

u = v - at

u = 0 - (-9.8)(1.75)

∴ u = 17.15 m/s

Thus, the boy should throw the ball at a speed of 17.15 m/s.

What is inequality function?

Since an inequality is merely a particular kind of relation, we can graph it just like we would any other relation. When dealing with inequalities, the trick is to shade large portions of the graph rather than using lines to connect the dots. But you could use some cover.

The given inequality function be like

The ordered pair refer to the solution set that provided by plotting the graph of the inequality, that expressed the inequality where an equation, plotting the graph along with a solid line, and shading the sides should be above the line of the graph to show the greater than or equal to sign.

Answer:

Step-by-step explanation:

If the discriminant of a quadratic function is 64 and its vertex is in quadrant III, here are three things you can know about the function and/or its graph:

The function has two distinct real roots. The discriminant of a quadratic function is the value under the square root in the quadratic formula:

x = (-b +/- √(b^2 - 4ac)) / 2a

If the discriminant is positive, it means that there are two real roots (values of x that make the equation equal to zero). If the discriminant is negative, it means that there are no real roots (the equation has no solutions). If the discriminant is zero, it means that there is only one real root (the equation has one solution). Therefore, if the discriminant is 64, it means that the function has two distinct real roots.

The graph of the function is a parabola that opens downward. The direction in which a parabola opens (upward or downward) is determined by the coefficient of the x^2 term (a). If a is positive, the parabola opens upward. If a is negative, the parabola opens downward. In this case, the vertex of the parabola is in quadrant III.

The solution to the system of equations is x = −7 and y = −1.

To solve the given system of equations using an inverse matrix, we can represent the system in matrix form, Ax=B, then find the inverse of matrix A to solve for 'x'.

Given matrix:

[tex]\left\{\begin{array}{ccc}x-6y=-1\\-2x+9y=5\end{array}\right[/tex]

[tex]\hrulefill[/tex]

First, we rewrite the system of equations in matrix for, Ax=B:

[tex]A = \left[\begin{array}{cc}1&-6\\-2&9\\\end{array}\right], \ x = \left[\begin{array}{cc}x\\y\\\end{array}\right], \ B = \left[\begin{array}{cc}-1\\5\\\end{array}\right][/tex]

So, Ax=B can be written as:

[tex]\Longrightarrow \left[\begin{array}{cc}1&-6\\-2&9\\\end{array}\right] \left[\begin{array}{cc}x\\y\\\end{array}\right] = \left[\begin{array}{cc}-1\\5\\\end{array}\right][/tex]

[tex]\hrulefill[/tex]

[tex]\boxed{\left\begin{array}{ccc}\text{The inverse of a 2x2 matrix,} \ \left(\begin{array}{ccc}a&b\\c&d\end{array}\right), \ \text{is given by:}\\\\\\A^{-1}= \dfrac{1}{ad-bc}\left(\begin{array}{ccc}d&-b\\-c&a\end{array}\right)\end{array}\right}[/tex]

Here,

[tex]\Longrightarrow A = \left[\begin{array}{cc}1&-6\\-2&9\\\end{array}\right][/tex]

The determinant ∣A∣ is:

[tex]\Longrightarrow |A|=(1)(9)-(-6)(-2)=9-12\\\\\\\\\therefore |A|=-3[/tex]

Since the determinant is not zero, A has an inverse, which can be calculated as:

[tex]\Longrightarrow A^{-1}= \dfrac{1}{-3}\left(\begin{array}{ccc}9&6\\2&1\end{array}\right)\\\\\\\\\therefore A^{-1}=\left(\begin{array}{ccc}-3&-2\\-2/3&-1/3\end{array}\right)[/tex]

[tex]\hrulefill[/tex]

We can solve for 'x' using x=A⁻¹B:

[tex]\Longrightarrow x = \left(\begin{array}{ccc}-3&-2\\-2/3&-1/3\end{array}\right)\left(\begin{array}{cc}-1\\5\\\end{array}\right)[/tex]

Upon multiplication, we get:

[tex]\Longrightarrow x = \left(\begin{array}{cc}(-3)(-1)+(-2)(5)\\(-2/3)(-1)+(-1/3)(5)\\\end{array}\right)\\\\\\\\\Longrightarrow x = \left(\begin{array}{cc}3-10\\2/3-5/3\\\end{array}\right)\\\\\\\\\Longrightarrow x = \left(\begin{array}{cc}-7\\-3/3\\\end{array}\right)\\\\\\\\\therefore \boxed{\boxed{x=\left(\begin{array}{cc}-7\\-1\\\end{array}\right)}}[/tex]

Thus, the solution to the system of equations is x = −7 and y = −1.

If the father is 22 years older than his son, and the sum of their ages is 38 years, we can set up the following equations to represent this information:

Matthew Westhoven deposited $925 in a new regular savings account that earns 5.5% interest compounded semiannually for 1 year. 51.09 is the compound interest.

The interest you earn on interest is known as compound interest. Simple math may be used to demonstrate this: if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year. You will wind up with $110.25 at the conclusion of the second year.

Given that,

principal amount (P) = $925

number of times interest applied per time period (n) = semiannually = 6

number of time periods (t) = 1 year

Thus, formula becomes:

[tex]I = P (1 + r/n)^{nt} - P[/tex]

or, [tex]I = 925 (1 + 5.5/6*100)^{1*6} - 925[/tex]

or, [tex]I = 925 (1.009)^6 -925[/tex]

or, [tex]I = 925 *(1.055) -925[/tex]

or, [tex]I = 976.09 -925[/tex]

or, [tex]I = 51.09[/tex]

Thus, the compound interest becomes 51.09

Based on the triangle midsegment theorem, the length of CZ is calculated as: 7.2 m.

The triangle midsegment theorem states that when two sides of a triangle are joined together by a line segment at their midpoint, the line segment is called the midsegment, and it is parallel to the third side whose measure is twice its length.

This implies that, AB is a midsegment in the image shown for triangle XYZ. It is parallel to YZ.

Therefore:

AB = 1/2(the length of YZ)

Substitute the value of AB into the equation:

7.2 = 1/2(YZ)

2(7.2) = YZ

YZ = 14.4 m.

The length of CZ = 1/2(the length of YZ) [this is because YC = CZ]

Answer:

-1.5 || -0.1 || 0.8 || 1.1

Explanation:

Since it is from least to greatest, let's compare the 2 negative numbers -1.5 and -0.1.

-1.5 has a 1 in its first place while -0.1 has a 0. This means that -1.5 is smaller because the further a number is on the negative number line the smaller it is.

So, -1.5 is the smallest, then -0.1.

-1.5 || -0.1

Now we compare the 2 positive numbers 0.8 and 1.1.

0.8 has a 0 in its first place and 1.1 has a 1 in its first place. Because the numbers are positive, the number with the biggest digit in in front of the decimal is greater.

So, in this case 1.1 is greater than 0.8.

0.8 || 1.1

In order it is:

-1.5 || -0.1 || 0.8 || 1.1
