Answer:

x = 11

Step-by-step explanation:

x + 9 = 20 (Subtract 9 from both sides)

x = 20 -9

x = 11

Verify:

11 + 9 = 20 (Correct)

Answer:

Let's represent the unknown number with the variable, x.

The word "difference" indicates subtraction and "times" indicates multiplication.

The "difference of 8 and six times a number" would be represented as:  8 - 6x

NOTE: The order of the terms is important (8- 6x is not the same as 6x - 8).

This expression 8 - 6x must be at least 68 to meet the requirement of being at least a "minimum".

The final inequality will be:   8 - 6x  ≥ 68

Step-by-step explanation:

hope this helps   :)

Answer:

5

Step-by-step explanation:

you need to find a pattern to write an equation first and the constant term ( aka as y-intercept , where the graph touches the y-axis) is the initial value

we se that each y= x+5 ( 7=2+5, 9=4+5, ...) so the initial value was 5

if x wold be 1 then y is 5

Answer:

[tex]-3\frac{1}{2}<-3\frac{1}{3}[/tex]

Step-by-step explanation:

-3.5 means -(3 + [tex]\frac{1}{2}[/tex])

In other words, -3.5 = [tex]-3\frac{1}{2}[/tex]

When we draw two numbers [tex]-3\frac{1}{3}[/tex] and [tex]-3\frac{1}{2}[/tex] on a number line, [tex]-3\frac{1}{2}[/tex] comes first from left to right.

We know that all the numbers on a number line from left to right are in increasing order.

Therefore, [tex]-3\frac{1}{2}[/tex] is smaller than [tex]-3\frac{1}{3}[/tex].

[tex]-3\frac{1}{2}<-3\frac{1}{3}[/tex]

Lauren is not correct.

Options :

y – 8 = –0.15(x – 10)

y + 8 = –0.15(x – 10)

y – 8 = –0.2(x + 10)

y + 8 = –0.2(x – 10)

Answer:

y – 8 = –0.2(x + 10)

Step-by-step explanation:

(-10, 8)

General equation in point - slope form:

y - y1 = m(x - x1)

m = slope

Given the points : ( - 10, 8)

x1= - 10 ; y1 = 8

y - y1 = m(x - x1)

Substitute the values of x and y into the equation :

y - 8 = m(x - - 10)

y - 8 = m(x + 10)

The best option which fits is :

y – 8 = –0.2(x + 10)

Answer:

3 down, 4 up

Step-by-step explanation:

-3 is the X line, which starts on 0, if you subtract 3, or add -3, you would have to go down, 3 down. 4 is on the Y line, so you add, go left to add on the Y line, 4 up.

Always start with you X coordinate. Here is a tip to help you (X, Y)

Answer:

x= 1/2

Step-by-step explanation:

Let's solve your equation step-by-step.

−2x+3−5x−4=−3x−8+10x

Step 1: Simplify both sides of the equation.

−2x+3−5x−4=−3x−8+10x

−2x+3+−5x+−4=−3x+−8+10x

(−2x+−5x)+(3+−4)=(−3x+10x)+(−8)(Combine Like Terms)

−7x+−1=7x+−8

−7x−1=7x−8

Step 2: Subtract 7x from both sides.

−7x−1−7x=7x−8−7x

−14x−1=−8

Step 3: Add 1 to both sides.

−14x−1+1=−8+1

−14x=−7

Step 4: Divide both sides by -14.

Answer:

6√2

Step-by-step explanation:

from the graph the coordinates of the points are (2, 5) and (- 4, -1)

the distance is d= √(x2-x1)²+(y2-y1)² = √(-4-2)²+(-1-5)²=√72 = √2*2*2*3*3= 6√2

Answer:

1/6 ; 2/6 ; 2/6

Step-by-step explanation:

To split 5/6 into. 3 different fractions with the same denominator and different numerator values;

The integer value of the numerator 5 can be divided into 3 different whole Number values ;

It could be :

5 = 3 + 1 + 1

5 = 2 + 2 + 1

Hence, we could have ;

3/6 +. 1/6 + 1/6

Or

2/6 + 2/6 + 1/3

Step-by-step explanation:

1. Factor out common terms in the first two terms, then in the last two terms.

[tex]2x + 3 + 2x + 3 + 2x + 3 + 2x + 3[/tex]

2. Collect like terms.

[tex](2x + 2x + 2x + 2x)(3 + 3 + 3 + 3 )[/tex]

3. Simplify.

[tex]8x + 12[/tex]

4. Factor out the common term.

[tex]4(2x + 3[/tex]

Therefor, the answer is 4(2x + 3)

Answer:

In the triangle below the red side is a leg and should be labeled a . The pink side is a leg and should be labeled b. and the light blue side is the hypotenuse and should be labeled c.

In right triangles the angles are labeled with upper case letters and the sides are labeled with lower case letters.

Answer:

Slope intercept form: y = 4/5x - 2

Step-by-step explanation:

(subtract 4x from both sides) -5y = -4x + 10

(divide everything by -5) y = 4/5x - 2

To graph, place a point at (0,-2), and then travel up 4 and over right 5 (or down 4 and to the left 5) to place the next point, then draw a line through the points

Answer:

18+2x

Step-by-step explanation:

Let the number be x.

Translate: 2x + 18 = x - 4.

Subtract x from each side:  x + 18 = -4.

Subtract 18: x = -22.

Check:  2(-22) + 18 = -44 + 18 = -26;  -22 - 4 = -26.

8 increased by twice a number​  = 18+2x

A linear equation has one or two variables.
