Answer:

3x^2-7

-7 is the constant

3 is the coefficient

x is the variable

Step-by-step explanation:

(3x^2)+(-7)

Answer:

Reciprocal

Step-by-step explanation:

That's it right there

Let the missing number be x .

Then :-

[tex]4(11 + 7) = x + 28[/tex]

[tex]4 \times 18 = x + 28[/tex]

[tex]72 = x + 28[/tex]

[tex]x + 28 = 72[/tex]

[tex]x = 72 - 28[/tex]

[tex]x = 44[/tex]

Therefore , 4 ( 11 + 7 ) = 44 + 28 .

Answer:

yes

Step-by-step explanation:

Substitute x = - 8 and y = - 7 into the equation

If both sides are equal then (- 8, - 7) is a solution

left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14

right side = 2y = 2(- 7) = - 14

Since both sides are equal then (- 8, - 7) is a solution to the equation

[tex]A.[/tex] [tex]y = \frac{5}{2}x + 1[/tex]

Step-by-step explanation:

Because if look closely at the top arrow it lines on 5 and 2 so that would be [tex]\frac{5}{2}[/tex] and then + 1 because it is also on the 1.

What is Linear Equation in 2 variables?

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

Given data ,

g ( x ) = x² - 5 x + 8

To solve for g ( 5 a - 2 ) + 3 g ( 2 a ) , substitute for the value of x

Therefore ,

g ( 5 a - 2 ) = ( 5 a - 2 )² - 5 ( 5 a - 2 ) + 8

                  = ( 25 a² + 4 - 20 a ) - 25 a + 10 + 8

                  = 25 a² - 45 a + 22

3 g ( 2 a ) = 3 [ (2 a )² - 10 a + 8 ]

                = 3 [ 4 a² - 10 a + 8 ]

                = 12 a² - 10 a + 8

And , g ( 5 a - 2 ) + 3 g ( 2 a ) = 25 a² - 45 a + 22 + ( 12 a² - 10 a + 8 )

                                               = 37 a² - 55 a + 30

Hence , the value of the equation will be 37 a² - 55 a + 30

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Step-by-step explanation:

Given: A line is drawn between points [tex](x_2,x_1)\,,\,(y_2,y_1)[/tex]

To find: distance between the two points

Solution:

A coordinate plane is a two-dimensional plane formed by the intersection of a  y-axis and x-axis. x-axis and y-axis are perpendicular lines that intersect each other at the origin.

Let d denotes distance between the two points [tex](x_2,x_1)\,,\,(y_2,y_1)[/tex]

Use the formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The distance between the two points show on the coordinate plane is D = √[(x₂-x₁)²+(y₂-y₁)²]. Therefore, the correct answer is option C.

The given coordinate points are (x₁, y₁) and (x₂, y₂).

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula.

On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is

Distance = √[(x₂-x₁)²+(y₂-y₁)²].

Therefore, the correct answer is option C.

Answer:

Step-by-step explanation:

The LCM (lest common multiple) of 6 and 8 is  24

the multiples of 8 are 8, 16, 24, 32...

the multiples of 6 are 6, 12, 18, 24, 30...

They have 24 in common, so 24 is the answer

Answer:

B: 24

Step-by-step explanation:

the multiples of 8 are 8, 16, 24, 32...

the multiples of 6 are 6, 12, 18, 24, 30...

24 is the least common multiple that id the same with both numbers

Answer:

Equation: 25% x n = 24

n = 96

Step-by-step explanation:

Because of means to multiply 25% OF n would mean you multiply to solve for n you would do the opposite which is dividing. 25% is the same as .25 so you would do...

24 ÷ .25 = 96

So 96 = n

Answer:

35 ml of 28% acidic solution and 65ml of 45% acidic solution is to be used

Step-by-step explanation:

Let the number of ml of the 45% solution be x while that of the 28% solution be y

Mathematically;

x + y = 100 ••••••(i)

Furthermore

45% of x + 28% of y = 33.95% of 100

0.45x + 0.28y = 33.95 ••••••(ii)

From i,

x = 100-y

put this into ii

0.45(100-y) + 0.28y = 33.95

45 - 0.45y + 0.28y = 33.95

45 - 33.95 = 0.45y - 0.28y

11.05 = 0.17y

y = 11.05/0.17

y = 65

Recall

x = 100 - y

x = 100 - 65

x = 35 ml

Answer:

(x + 1 ) is a factor

Step-by-step explanation:

Given a polynomial with roots x = a, x = b , then the corresponding factors are

(x - a) and (x - b)

From the graph

The roots are x = - 1 and x = 4 , thus factors are

(x - (- 1)) and (x - 4) , that is

(x + 1) and (x - 4)

(x + 1) is the required factor

Answer:

Number of trucks (y) that can be shipped if the number of cars (x) is known[tex]=\frac{21,600-3.6x}{7.5}[/tex]

Step-by-step explanation:

A cargo ship can carry 21,600 Tons.

Let x denotes number of cars and y denotes number of trucks.

The cars weigh 3.6 tons each and the trucks weigh 7.5 tons each.

Therefore,

[tex]3.6x+7.5y=21,600[/tex]

Now write y in terms of x.

[tex]7.5y=21,600-3.6x\\y=\frac{21,600-3.6x}{7.5}[/tex]

Number of trucks (y) that can be shipped if the number of cars (x) is known[tex]=\frac{21,600-3.6x}{7.5}[/tex]
