Answer:

85 degrees

Step-by-step explanation:

its really easy just make them equal to eachother and then solve

9x + 13 = 11x-3

-11x (subtract because 11x is positive)

-2x +13 = -3

-13 (subtract because 13 is positive)

-2x = -16

divide both sides by -2

x= 8

substitute 8 for the x's and you have your answer

The system of inequalities describes Tamara’s investment options are as follows:

[tex]8000\leq x[/tex]

[tex]3y\leq x[/tex]

Step-by-step explanation:

Total amount with Tamara = $30,000

Let [tex]x[/tex] be the amount invested in corporate bonds, and let [tex]y[/tex] be the amount invested in municipal bonds.

She wants to invest no less than $8,000 into corporate bonds.

So, the inequality is [tex]8000\leq x[/tex]    

Also, she wants to invest at least three times as much into corporate bonds than into municipal bonds.

[tex]3y\leq x[/tex]    

The system of inequalities describes Tamara’s investment options are as follows:

[tex]8000\leq x[/tex]

[tex]3y\leq x[/tex]

Answer: y=1/4+3

Step-by-step explanation:

1. The slope is 12

2. (6 - 2)/(12+4)= 4/16= 1/4

y - 2 = 1/4(x + 4)

y - 2 = 1/4x + 1

y = 1/4x + 3

Answer:

y= -2(x-4)

Step-by-step explanation:

I got it right on the tutorial...

Answer:

x=0.2, y=6

Step-by-step explanation:

Since y=20x+2, 5x+y=7 => 5x + (20x +2 ) = 7

                                                     25x + 2 = 7

                                                           25x = 5

                                                                x = 0.2

so y = 20x + 2 = 20* 0.2 +2 = 4 + 2 = 6

so the final solution is [tex]\left \{ {{y=6} \atop {x=0.2}} \right.[/tex]

The values of x and y for the given simultaneous equation are;

x = 0.2 and y = 6

We are given 2 simultaneous equations;

5x + y = 7   ---(eq 1)

20x + 2 = y   ----(eq 2)

Put 20x + 2 for y in eq 1;

5x + 20x + 2 = 7

25x + 2 = 7

25x = 7 - 2

25x = 5

x = 5/25

x = 0.2

Put 0.2 for x in eq 2 to get;

20(0.2) + 2 = y

4 + 2 = y

y = 6

In conclusion, the values of x and y are x = 0.2 and y = 6.

We need to use the place values to compare different numbers.

By only looking at the place value, we can see that the largest number is: 0.1

Let's see how to get the solution.

We can define place value as the place where a digit is with respect to the decimal point.

The digits that are at the far left are the larger ones, for example in:

11

The left one represents 10, while the right one represents 1:

10 + 1 = 11

The same happens when we look at the right of the decimal point, there the digits at the left will be larger than the ones at the right.

0.10 is larger than 0.01

From this, we can see that for the set:

{0.1, 0.02, 0.003, 0.0004, 0.00005}

The largest number will be the one with the leftmost first digit different than zero, which is the first one: 0.1

Given:

A rectangle has a length 5 meters more than five times the  width.

The area of the rectangle is less than 100 meters  squared.

To find:

The expression or inequality that represents all possible  widths of the rectangle.

Solution:

Let x be the width of the rectangle.

Length of the rectangle is 5 meters more than five times the  width.

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

Area of rectangle is

[tex]Area=length \times width[/tex]

[tex]Area=(5x+5) \times x[/tex]

[tex]Area=5x^2+5x[/tex]

The area of the rectangle is less than 100 meters  squared.

[tex]5x^2+5x<100[/tex]

[tex]5x^2+5x-100<0[/tex]

Divide both sides by 5.

[tex]x^2+x-20<0[/tex]

[tex]x^2+5x-4x-20<0[/tex]

[tex]x(x+5)-4(x+5)<0[/tex]

[tex](x+5)(x-4)<0[/tex]

It is true if one factor is negative and other is positive. So,

[tex]x-4<0\Rightarrow x<4[/tex]     ...(i)

[tex]x+5>0\Rightarrow x>-5[/tex]       ...(ii)

Using (i) and (ii), we get

[tex]-5<x<4[/tex]

Therefore, the required expression or inequality for possible

widths of the rectangle is [tex]-5<x<4[/tex].

Step-by-step explanation:

remember the rule for 90 degree clockwise is (-y,x) opposite y and x

the negative in there DOES NOT mean it will always be negative it means opposite but in this case yes it's negative because the opposite of positive is negative

The image of point (0,2) after a rotation of 90° counterclockwise about the origin is (-2, 0).

The given coordinate point is (0, 2).

Here are the rotation rules: 90° clockwise rotation: (x, y) becomes (y, -x) 90° counterclockwise rotation: (x, y) becomes (-y, x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y).

The rule of 90° counterclockwise rotation: (x, y) becomes (-y, x), here

(-2, 0)

Therefore, the image of point (0,2) after a rotation of 90° counterclockwise about the origin is (-2, 0).

Answer:

Step-by-step explanation:

1) Upon studying the grid, we see that A is at the intersection of the x- and y-axes, and that all of the other points are in the first quadrant. The distance between minor grid lines in either direction is taken to be 1 unit. That is, B is 1 unit right and 1 unit up from A(0, 0), so has coordinates B(1, 1).

The coordinates of C and D can be found by counting grid lines. We find them to be C(5, 1) and D(8, 7).

__

2) The line joining A and B is a line whose points have their x-coordinate equal to their y-coordinate. The coordinates of D are not equal, so will not be on that line.
