Given:

The expression is

[tex]-9xy^2z[/tex]

To find:

The coefficient of x in the given expression.

Solution:

Coefficient of a variable is the product of a number and other variables multiplying the variable in an algebraic expression.

In the given expression the number and variables other than x are -9, y² and z.

So, coefficient of x is

[tex]-9\times y^2\times z=-9y^2z[/tex]

Therefore, the correct option is (d).

Answer:

1164

Step-by-step explanation:

Surface area is the sum of the areas for all the faces. So 20×15= 300 since there is another one like that you multiply that answer by 2. Then 16×12= 192 then repeat and multiply 192 by 2. Then 12×15= 180 and since there is only one you dont multiply it by 2. Now add (192×2) + (300×2) + 192.

384 + 600 + 192 = 1164

Answer:

12x -2 = 22

12x = 22 +2

12x = 24

x = 24/12

x= 2

therefore, the vale of x =2.

Answer: 1000(1.05)^X or C

Step-by-step explanation: F(x) = a(1+r)^X

A = Initial amount, which is 1000

r = growth rate, which is .05, and you add 1 to that

So it's 1000(1.05)^X

Answer: Its the second choice

Step-by-step explanation: square area is base x height; the base is 12 the height is 4. triangle area = (base x height)/ 2; base is 12, times 4 (height), then divide by 2

Answer:

The nth term is 3n+2.

The given sequence is in A.P.

Here,

First term,a= 5

Common difference,d= 3

Therefore the nth term = a+(n-1)d =5+(n-1)3

=5+3n-3 =3n+2.

Answer:

x = 13

Step-by-step explanation:

Right Triangles

In a right triangle, there is an internal angle of 90°. The other two must add up to 90°.

The trigonometric ratios are satisfied in a right triangle. The tangent ratio, for example, is defined as:

[tex]\displaystyle \tan 35^\circ=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

The angle of 35° is adjacent to the side of length 18 and is opposite to the side of length x, thus:

[tex]\displaystyle \tan 35^\circ=\frac{x}{18}[/tex]

Solving for x:

[tex]x=18\tan 35^\circ[/tex]

This is the equation to solve. Now substitute the tangent for its value to get

x = 13

Answer:

1. First choice

2. Image C

3. Fourth chioice

4. Third choice

5. First choice.

Step-by-step explanation:

Solve the equation.

[tex] {x}^{2} - 9 = 0[/tex]

Use the difference of two squares formula.

[tex] {x}^{2} - {y}^{2} = (x + y)(x - y)[/tex]

[tex](x + 3)(x - 3) = 0 \\ x = 3, - 3[/tex]

A linear relationship already says it all. Find the graph that is NOT a curve. The only image that is not a curve and the graph straight forwards is the Image C aka A choice.

A nonlinear function is a function that does not have a straight line graph. All linear functions are linear, except for Quadratic and up. Every polynomial function with the degree greater than one wont be a linear.

[tex]y = x + 3[/tex]

If we change the constant from 3 to 5 then we would get

[tex]y = x + 5[/tex]

The graph would shift up 2 units.

The second and third graph both are function. We can tell by doing a line test. Simply draw a vertical line first. Then we check if the line intercepts the graph more than a point or not.

If the line intercepts more than a point then it is not a function.

If the line intercepts only a point then it is a function.

Answer:

Yes it is

Step-by-step explanation:

Step-by-step explanation:

Since both lines intersect each other 3 units above the x-axis, the y-value of the point of intersection must be 3.

Looking at the options, (-3, 5), (3, -2) and (0, -3) are all invalid points.

The points that can not be the intersection points are:

(-3, 5), (3, -2), and (0, -3)

Options B, C, and D are the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

A line with a negative slope intersects a horizontal line 3 units above the x-axis.

This means,

The y-coordinate will be 3.

The y-intercept is y = 3.

The points of intersection will have the following form,

= (x, 3)

Thus,

(-3, 5), (3, -2), and (0, -3) can not be the intersection points.

Step-by-step explanation:

You should first write an equasion to represent the question.

There are 2 ways you can write this → x+2+x+2+7+7 or 2(x+2)+2(7)

Then Simplify = To check the answer plug the answer back in ->14+4+14=32

The number of 20 veggie burger, you bought.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

You buy a total of 50 turkey burgers and veggie burgers for $90.

You pay $2 per turkey burger and $1.50 per veggie burger.

Let x represents the turkey burger and y represents the veggie burger.

So, the system of equations,

x + y = 50   equation 1

2x + 1.5y = 90    equation 2

Substituting the value of x from the equation 1 to the equation 2,

100 - 2y + 1.5y = 90

y = 20

Then x = 30

Therefore, 20 veggie burgers you bought.
