Cramer's rule is one of the useful methods used for solving a system of equations. In this method, the values of the variables in the system are to be calculated using the determinants of matrices. Thus, Cramer's rule is also known as the determinant method.

Given that: John buys 7 apples and 4 pears for $7.25 and at the same prices, Hayley buys 5 apples and 9 pears for $10.40

We will use this given information to form equations in matrices form. Let a and p represent the prices of one apple and one pear respectively.

The equation is:

7a + 4p = 7.25

5a + 9p = 10.40

The matrix formed is:

[tex]C=\left[\begin {array}{ccc}7&4\\5&9\end{array}\right][/tex] ,   [tex]b=\left[\begin {array}{ccc}7.25\\10.40\end{array}\right][/tex]

Find the determinants,

D =  (7 x 9) - (5 x 4) = 43

Da =  (7.25 x 9) - (10.40 x 4) = 23.65

Dp =  (7 x 10.40) - (5 x 7.25) = 36.55

a = Da/D = 23.65/43 = 0.55

p = Dp/D = 36.55/43 = 0.85

Since p = 0.85. Therefore, the price of one pear is $0.85

The equation of the linear function is y=8x+(-8).

What do you mean by equation?

A mathematical statement with two expressions that have the same value and the sign "equal to" between them is called an equation. Take the example of 3x + 5 = 15. Equations can be of several sorts, including linear, quadratic, cubic, and others.

According to data in the given question,

We have points (0,-8) and (1,0), thus

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\=\frac{(0-(-8))}{1-0} \\=8[/tex]

Then

y=8x+b

Points (0,-8) means that when x=0, y=-8 and we use this to find b,

y=8x+b

-8=8(0)+b

-8=0+b

b=-8

So, y=8x+(-8)

Therefore, the equation of the linear function is y=8x+(-8).

-6t -54  is the expression equivalent to-6(t+9)

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we substitute the same value(s) for the variable(s)

Given: -6(t+9)

First, clear the parenthesis by using -6 to multiply t and 9:

-6(t+9) = (-6 x t) + (-6 x 9)

          = -6t + (-54)

          = -6t -54

Therefore, the -6t -54 is equivalent to -6(t+9)

Step-by-step explanation:

Step-by-step explanation:

4x² + 12x + 8 = 0

this has the same solutions as

x² + 3x + 2 = 0

as we simply divided everything by 4. 0/4 = 0.

the general solution to such a quadratic equation

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case that is

x = (-3 ± sqrt(3² - 4×1×2))/(2×1) =

= (-3 ± sqrt(9 - 8))/2 = (-3 ± sqrt(1))/2

x1 = (-3 + 1)/2 = -2/2 = -1

x2 = (-3 - 1)/2 = -4/2 = -2

so, the 2 solutions are

x = -1

or

x = -2

The probability of picking a shirt that is red or striped is 2/3.

Given, that a drawer of shirts contains 3 solid red, 2 striped red, 4 solid blue, and 3 striped green.

We have to find the probability of picking a shirt that is red or striped,

P(R ∪ S) = P(R) + P(S) - P(R∩S)

where, R be the event that the shirt is red.

and S be the even that the shirt is striped.

P(R) = 5/12 (as, there are 5 red shirts)

P(S) = 5/12 (as, there are 5 striped shirts)

P(R∩S) = 2/12 (as, there are 5 striped red shirts)

P(R ∪ S) = 5/12 + 5/12 - 2/12

P(R ∪ S) = 8/12

P(R ∪ S) = 2/3

The interval where the product will be at least break even equals to 18 units.

In accounting, the break-even point refers to the production level at which total revenues equal total expenses.

Given data

Cost is given as C = 45x + 450

Revenue is given as: R = 70x

In this case, the point of breakeven will be:

Cost = Revenue

45x + 450 = 70x

We will collect like terms:

70x - 45x = 450

25x = 450

We will divide both side by 25:

25x/25 = 450/25

Answer:

10th term

Step-by-step explanation:

given [tex]T_{n}[/tex] = 5n + 2 and [tex]T_{n}[/tex] = 52 , then equate right sides and solve for n

5n + 2 = 52 ( subtract 2 from both sides )

5n = 50 ( divide both sides by 5 )

n = 10

that is the 10th term has a value of 52

The constant of variation is 1.75 for every unit increase in x (weight), and the cost(y) value increases by $ 1.75.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The difference between two consecutive entries is constant, as we can see = 1.75

⇒ 7 - 5.25 = 1.75

⇒ 8.75-7 = 1.75

⇒ Slope(m) = 1.75

The slope represents the variable's rate of change.

y - 3 = m(x - 5.25)

y - 5.25 = 1.75(x-3)

y = 1.76x

Thus, the constant of variation is 1.75

This indicates that for every unit increase in x (weight), the cost(y) value increases by $ 1.75.

Measure of largest. smallest and middle angle of a triangle under given conditions is 145°, 15° and 20° respectively.

What is angle sum property of a triangle?

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

According to the given question:

Let the measure of middle angle = x

The measure of the smallest angle is three-quarters the measure of the middle angle.

∴ Smallest angle = (3/4)x

The measure of the largest angle in a triangle is 110° larger than the sum of the measures of the other two angles.

∴ Largest angle = 110° + x + (3/4)x

Now, by Angle sum property of a triangle

x + (3/4)x + 110° + x + (3/4)x = 180°

On solving for the value of x we get

2x + (3/2)x = 70°

7x = 140°

x = 20°

Therefore,

measure of middle angle x = 20°

measure of smallest angle (3/4)x = 15°

measure of the largest angle 110° + x + (3/4)x = 145°

Answer:

Step-by-step explanation:

4(7y + x) = 4             Distribute the 4 to 7y and x

28y + 4x = 4            Subtract the 4x on both sides

28y = 4 - 4x            To get 'y' by itself divide 28 on both sides

y = 4/28 - 4x/28      You can simplify the 4/28 since 4 goes into 28 7 times

y = 1/7 - x/7

the equation for meters is usually as you see in the picture but for this exercise it got rounded from -4.9 to -5, which is fine.

let's notice that "t"  has two values, however the seconds cannot be a negative value, so we dismiss that one.

The ball will strike the ground 4 seconds after it is thrown When an object is thrown upward, its height , in meters, is given by the quadratic equation S = -5t² + vt + h

To find the time at which the ball will hit the ground, we need to determine when the height (S) of the ball becomes zero. At that moment, the ball will be at ground level.

The height (S) of the ball is given by the quadratic equation:

S = -5t² + vt + h

where:

S = height of the ball in meters

t = time of flight in seconds

v = initial velocity in meters/second (upward velocity, so it's positive)

h = height above level ground from which the object is thrown

Given that the initial velocity (v) is 16 meters/second, and the height above the ground (h) is 16 meters, we can substitute these values into the equation:

S = -5t² + 16t + 16

Now, to find the time (t) at which the ball hits the ground, we need to solve for t when S = 0:

0 = -5t² + 16t + 16

This is a quadratic equation in standard form (ax² + bx + c = 0), and we can solve it by factoring or using the quadratic formula. In this case, let's use the quadratic formula:

The quadratic formula is given by:

t = (-b ± √(b² - 4ac)) / 2a

In our case, a = -5, b = 16, and c = 16. Plugging these values into the quadratic formula:

t = (-(16) ± √(16² - 4*(-5)16)) / 2(-5)

t = (-16 ± √(256 + 320)) / -10

t = (-16 ± √576) / -10

Now, find the two possible solutions for t:

t₁ = (-16 + √576) / -10

t₁ = (-16 + 24) / -10

t₁ = 8 / -10

t₁ = -0.8 seconds

t₂ = (-16 - √576) / -10

t₂ = (-16 - 24) / -10

t₂ = -40 / -10

t₂ = 4 seconds

We have two solutions for t: t = -0.8 seconds and t = 4 seconds. However, we can disregard the negative value for time, as time cannot be negative in this context.

So, the ball will strike the ground 4 seconds after it is thrown.

A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway. In addition, the halfway is reached if a line is drawn to divide the line that connects these two places. When we know the coordinates of two points, we can apply the midpoint formula to get the midpoint between them.
