Solve for d.

3 + d ≤ 3 - d

Answers

Answer 1

Answer:

[tex]3 + d \leqslant 3 - d \\ d + d \leqslant 3 - 3 \\ 2d \leqslant 0 \\ d \leqslant 0 \\ thank \: you[/tex]

Answer 2

1) Cancel 3 on both sides

d≤−d

2) Subtract -d from both sides.

d+d≤0

3) Simplify  d+d  to  2d.

2d≤0

4)  Divide both sides by 2.  

d≤0

Answer:

1/3

Step-by-step explanation:

1. When we divide any x-input by the y-input, we get 3. This is the same as multiplying the x-input by 1/3 to get the y-input. Let's see if it works!

[tex]3 * \frac{1}{3} = \frac{3}{3} = 1[/tex] [tex]6 * \frac{1}{3} = \frac{6}{3} = 2[/tex] [tex]12 * \frac{1}{3}= \frac{12}{3}=4[/tex] [tex]15*\frac{1}{3}=\frac{15}{3} =5[/tex]

2. Great! All our x-inputs and y-inputs match up, meaning the constant of proportionality, k, is 1/3.

Graph the linear equation 5x-4y < 20

Answers

using a graphing calculator:

Answer: (See attached image file)

Step-by-step explanation:

Start by plotting given key features

Based on the problem, we know that the x-intercept is (0,4) We find this by plugging in 0 for y, and solving for x  (5x = 20)(x = 20/5 = 4)        (4, 0)  

We can also easily solve for the y-intercept, which is (0,-5)We find this by plugging in 0 for x, and solving for y(-4y = 20)(y = -5)      (0, -5)  

Since we know that the equation is linear, seeing as the highest exponent is 1, we know that these two points have to be connected by a single, straight line.

Finally, we shade in the side to the LEFT of the line. This is because the equation asks for LESS THAN. If however the question had been 5x-4y>20, we would shade in the region to the right.        

What type of dilation is formed when the scale factor K is greater than one

Answers

Answer:

Enlargement

Step-by-step explanation:

When k > 1, the dilation is an enlargement. When k > 0 and k < 1, the dilation is a reduction. In a dilation, the original figure and its image are similar. The ratio of the side lengths of the image to the corresponding side lengths of the original figure is the scale factor of the dilation.

1. Jose did not make an error. His estimate of $12 is correct.
2. Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
3. Jose incorrectly rounded 6.2 up to 7.
4. Jose incorrectly multiplied 2 and 7. The estimate should be $14.

Write the equation in slope intercept form. what are the slope and y-intercept? -3x - 10y = 7

Answers

Answer:

Slope: = 3/10x

y-intercept: = -7/10

Step-by-step explanation:

10y = -3x - 7

y = -3/10x - 7/10

Slope: = 3/10x

y-intercept: = -7/10

Type an equation for the
following pattern.

y=[? ]x+[ ]

Answers

y = -x + 6

To solve for the slope, choose two pairs of coordinates and substitute their values into the slope formula.

Let (x1, y1) = (1, 5)
(x2, y2) = (2, 4)

m = (y2 - y1)/(x2 - x1)

m = (4 - 5)/(2 - 1)
m = -1/1
m = - 1
Therefore, the slope, m = -1.

For the y-intercept, choose one of the given points, and use it along with the slope to solve for the y-intercept. Using point (2, 4) and the slope, m = -1, substitute their values into the slope-intercept form:

y = mx + b
4 = -1(2) + b
4 = -2 + b

Add 2 to both sides to solve for b:
4 + 2 = -2 + 2 + b
6 = b

Therefore, the linear equation is :

y = -x + 6

Find the measure of the marked angles.
The measure of the angles is
___ degrees

Answers

Answer:

43°

(4x + 19)° = (6x + 7)° [vertically opposite angles are equal]

4x+19 = 6x+7

4x + 19 -7 = 6x

4x +12 = 6x

12 = 6x - 4x

12 = 2x

2x = 12

x = 12/2

x = 6

Now replace the x with 6

(4x+19)°

= (4×6+19)°

= (24+19)°

= 43°

(6x+7)°

= (6×6+7)°

= (36+7)°

= 43°

The measure of the angles is 43 degrees
