Find the equation if the line shown

Answers

Answer:

y=1/2x+9

Step-by-step explanation:

First find slope: (y2-y1)/(x2-x1)
Pick two points: (0,9), (1,7)
(7-9)/(1-0) = -2/1 = -2
Y = -2x + b
9 = 0 + b, b = 9
Slope intercept equation:
Y = -2x + 9

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

Step 1:  Cross-Multiply

What cross multiply basically means is that you take both sides of the equation and you multiply my the opposite sides.  So you take the top of the left fraction and multiply it by the bottom of the right fraction.  You then have an equal sign and then have the bottom of the left fraction multiplied by the top of the right fraction.

[tex]\frac{2}{7}=\frac{6x}{4x+17}[/tex]

[tex]2(4x+17)=7(6x)[/tex]

Step 2:  Distribute

[tex]2(4x+17)=7(6x)[/tex]

[tex](2*4x)+(2*17)=(7*6x)[/tex]

[tex]8x+34=42x[/tex]

Step 3:  Subtract 8x from both sides

[tex]8x + 34- 8x = 42x - 8x[/tex]

[tex]34=34x[/tex]

Step 4:  Divide both sides by 34

[tex]34/34 = 34x/34[/tex]

9. Matt bought a new crate for his dog. The old crate was 8 square feet, and the new crate was 12 square feet. What is the percent increase in the space?

Answers

Solution:

It is given that :

Area of old crate = 8 square feet

Area of the new crate = 12 square feet

Therefore difference in the area = 12 - 8

                                                     = 4 square feet

Now the percentage increase in the area of the crate is given by :

[tex]$=\frac{\text{difference in the area of crate}}{\text{original area of crate}} \times 100$[/tex]

[tex]$=\frac{4}{8} \times 100$[/tex]

= 50%

So the percentage increase in space is 50%

Suppose you are constructing a LEGO Technic Land Rover Defender with a total of 2573 pieces. You have already put together 253 pieces. Every minute you add 5 more pieces. Is the relationship linear? How do you know?

Answers

Answer: Yes it is

Step-by-step explanation:

A linear relationship simply put, is a relationship between variables that when constructed, forms a straight line. This happens when y changes at a constant rate if x changes by a constant rate as well for instance, 1.

From this question, assume x is minutes and y is the total number of pieces put together. This means that every time x (minutes) increases by 1, y increases by 5 pieces.

The formula would look like this;

y = 5x + 253

This is a formula for a straight line so indeed, this relationship is linear.

Liza’s age is two more than thrice the age of her younger sister.if her sister is 5 years old, how old is Liza?

Answers

Answer:

17 years old.

Step-by-step explanation:

sisters age:5

5×3+2=17.

Answer:

Liza is 17 years old.

Step-by-step explanation:

Ley 'x' be the age of Liza's younger sister

As Liza’s age is two more than thrice the age of her younger sister

so the equation of Liza's age will be:

Liza's age = 3x+2

As x = 5 years is Liza's younger sister age

so

Liza's age = 3(5)+2

                 = 15+2

                  = 17 years

Therefore, Liza is 17 years old.

b)

y = 1/3 ( 21 - 9x)

y = -3x + 7

y = 3x + 2.5
