What is the value of x in the equation 3x – y = 18, when y = 27?
a.5
b.7
c.45
d.63

Answer:

(-3,0)

Step-by-step explanation:

So first we wanna find how for the x value is on point a to point b and how far the y value is from point a to point b. the x on point a is 9 units away from point b and y is 18 units away. Then we find out what 2/3s of 9 and 18 is which would be 6 and 12. So then we take the A coordinates (9,-6) and subtract 12 from the x value and 6 from the y value to get the new coordinates of (-3,0)

Answer:

-1 4/5, -1.7, -1 1/10, -1.

Step-by-step explanation:

We convert all of these to tenths. -1 4/5 becomes - 1 8/10. -1.7 becomes -1 7/10. -1 1/10 is already in tenths and -1 is a whole number. When putting these from least to greatest, remember that the bigger the negative, the less the number is.

Answer: -8c+24

Step-by-step explanation:

Answer:

It is simplified as x + 10.

Step-by-step explanation:

Convert the negative sign for the second parentheses equation to -6x + 2.  Your equation should now look like this 4x + 3 -6x + 2 + 3x + 5.  Combine the 3 x value terms and the 3 non-value terms together to get your simplified answer which is x + 10.

Answer:

x=8

y=4

Step-by-step explanation:

y=12-x

-2x+48=32

-2x=-16

x=8

8+y=12

y=4

Step-by-step explanation:

Answer:85

Step-by-step explanation: In this problem you are trying to find the missing angle of a line. In a line all angles have to add up to 180 so what you wanna do first is add 55 and 40 which gives you 95. Next, you wanna subtract 95 from 180 which will give you 85. Now you know the missing angle.

Answer:

Expand the polynomial using the FOIL method.

x^2−3x+2

Answer:

x^2 - 3x + 2

Step-by-step explanation:

x times x is x^2

x times - 1 is -1x

-2 times x is -2x

-2 times -1 is 2

x^2 - 3x + 2

Answer:

=4/1 or 4

Step-by-step explanation:

Remember Rise/Run

also remember this formula:

y2-y1/

x2-x1

Your coordinates are: (-2, 1) (-3, -3)

-3-1/

-3-(-2) = -4/-1  or 4

Two negatives cancel out and make it a positive.

The answer's -2 btw

Hope this was what you were asking

Given that the initial point of the vector is (1,-2) and the termination point of the vector is (0,0).

So, the tail of the vector is at point (1,-2) and the head of the vector is at (0,0). The vector, [tex]\vec{v}[/tex], has been shown in the figure.

The magnitude of the vector:

[tex]|\vec{v}|=\sqrt{(1-0)^2+(-2-0)^2}=\sqrt{1+4}=\sqrt{5}[/tex]

The direction of a vector is the angle made by a vector with the positive direction of the x-axis.

From the figure, [tex]\theta = 180 \degree\tan ^{-1} \left|\frac {0-(-2)}{0-1}\right|[/tex]

[tex]\theta = 180 ^{\circ} - \tan^{-1}(2) = 180 ^{\circ} - 63.43^{\circ}[/tex]

[tex]\theta =116.57 ^{\circ}[/tex]

Hence, the required vector having a magnitude [tex]\sqrt {5}[/tex] and direction [tex]116.57 ^{\circ}[/tex] has been shown in the figure.

Step-by-step explanation:

This is the answer upon dividing the polynomial.

Answer:

x ≈ 31.0°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tanx = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{9}{15}[/tex], then

x = [tex]tan^{-1}[/tex] ([tex]\frac{9}{15}[/tex] ) ≈ 31.0° ( to 1 dec. place )

Answer:

1135.28

Step-by-step explanation:

1102 * (1.02) = 1124.04

1124 * (1.01) = 1135.28

Answer:

1) B=-12

2) 189.69

Step-by-step explanation:

Explanation 1: To find B, we have to replace the given points in the equation, that is , x=2 and y=1

[tex]3x+By+6=0\\3.2+B.1+6=0[/tex]

Then we solve for B.

[tex]6+B+6=0\\B+12=0\\B=-12\\[/tex]

Hence , B=-12

explanation 2: you have the following equation for the number of liters 3% milk:

[tex]0.03+0.1(200)-x=0.05(200)[/tex]

Solve the previous equation for x:

[tex]0.03x+20-x=10[/tex]

[tex]0.03-x=10-20\\-0.97x=-10\\x=10.31[/tex]

Hence , there are 10.31 liters of 3% milk  

Add the numbers of liters 10% butterfat is :

[tex]200-10.31=189.69 liters[/tex]

Answer: $6,120

Step-by-step explanation:

There are 15 fruits in each basket.

The store shipped 3,825 fruits, to find the number of baskets of fruits shipped you have to divide 3,825 by 15.

3,825 ÷ 15 = 255

Each basket costs $24 so to find the cost of 255 baskets, you multiply 255 by 24.

$24 × 255 = $6,120

Leona earned $6,120 from the gift baskets sold.

Answer:

Step-by-step explanation:

We can solve this with some pretty simple substitution

First write that a=2b+8

and our reasoning for this is that we added 2b from the first equation

Then write

4(2b+8)+3b=21

After we figured out what A was in the previous part we are able to substitute that into our other equation

Then you solve for b from here

8b+32+3b=21

11b=-11

b= -1

Step-by-step explanation:

Answer:

0.625

Step-by-step explanation:

Given the points :

(0, 4) and (-8, -1)

x1 = 0 ; y1 = 4

x2 = - 8 ; y2 = - 1

Slope, m = rise / run

Rise = y2 - y1 = - 1 - 4 = - 5

Rise = x2 - x1 = - 8 - 0 = - 8

The slope, m = - 5 / - 8

Slope, m = 0.625

Answer:

9/4

Step-by-step explanation:

9 out of 4 are blue, just flip the ratio.

Answer:

4/13

Step-by-step explanation:

A ratio can be added up to find the denominator, and using that information, you can do 4+9=13. Then in order to find the blue sweets which are the 4 part, we just need to make it numerator to get 4/13.
