Answer:

Represent the length and width by L and W. Then L = W + 4.

Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).

Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.

The dimensions of the rectangle are 15 by 19 feet.

From the question, we have the following parameters that can be used in our computation:

The images of the scatter plots

Describing the scatterplot a

On the scatter plot, we can see that

The points appear to be on a straight line

Also, we can see that

As the x values increases the y values decreases

This represents a negative association.

Hence, the correlation is negative

Not sure

The new number has 4 zeros so the power was 4

Answer: 4

Answer:

4

Step-by-step explanation:

kaya started with 92

then multiplied it by

[tex]10 ^{x} [/tex]

[tex]92 \times {10}^{x} [/tex]

[tex]92 \times {10}^{x} = 920000[/tex]

divide both sides by the coefficient of

[tex] {10}^{x} [/tex]

[tex] {10}^{x} = \frac{920000}{92} [/tex]

[tex] {10}^{x} = 10000[/tex]

[tex] {10}^{x} = {10}^{4} [/tex]

since they both have the same numbers we can cancel the two 10

therefore:

x = 4

Answer:

a is less than or equal to 7

Step-by-step explanation:

This is the case because we can treat the less than or equal to sign as an equal sign. The only time it changes is when we divide by a negative, but we do not do that in this problem. First, you subtract 7 from both sides. That leaves us with a 4a on one side and a 28 on the other. Then, you divide both sides by four to get a is less than or equal to 7. I hope this helps!

Answer:

-8 -20 or - 8 - 20

correct me if I'm wrong

Answer: -28

Step-by-step explanation: the word "difference" in math means subtraction. so -8-20 is -28

Answer:

3/4 and 10/15 are not proportional

Step-by-step explanation:

3 is not a factor of 10 and 4 is not a factor of 15

Answer:

No

Step-by-step explanation:

3/4 is already simplified all the way, but 10/15 is not. 10/15 simplifies down to 2/3 (because 5x2=10 and 5x3=15), which is not equivalent to 3/4.

Answer:

if 1 equal to x

and 2 equal to x-4

that mean

(x)+(x-4)=180

2x-4=180

2x=184

x=92

lets start to find the angles that marked with numbers

1=92

2=88

3=88

4=92

5=92

6=88

7=88

8=92

Answer:

9x + y = 12

Step-by-step explanation:

Hi there!

We are given the equation y - 3 = -9(x-1) and we want to write it in standard form

The equation is currently in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where [tex](x_1 , y_1)[/tex] is a point and m is the slope. Standard form is ax + by = c, where a, b, and c are free integer coefficients

We can first convert the equation from point-slope form into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We can distribute 9 to every term on the right side:

y - 3 = -9x + 9

Now add 3 to both sides

y = -9x + 12

Now the equation is in slope-intercept form (y=mx+b). To make it standard form, add 9x to both sides, to make the form ax + by = c .

9x + y = 12

Hope this helps!

Step-by-step explanation:

The figure B is the scaled copy of the figure A.

The both figures are similar to each other.

The scale factor is the ratio of corresponding sides of figure B to A:

Answer:

1) x = 9

2) y = 16

3) y = -1

Step-by-step explanation:

Do PEMDAS in reverse.

For every equation, your goal is to seperate the variable (x,y, or whatever letter) by itself.

1) 2x-7 = 11

Add 7 to both sides.

2x = 18

Divide both sides by 2.

x = 9

2) [tex]\frac{3}{4}y = 12[/tex]

Divide both sides by 3/4 (which turns into multiplying by 4/3).

Left side

[tex]\frac{3}{4}x * \frac{4}{3}\\\\\frac{3}{4}x * \frac{4}{3} = \frac{3*4}{4*3}x\\1x\\x[/tex]

Right side

[tex]12*\frac{4}{3}\\\\\frac{12}{1} *\frac{4}{3}\\\\ \frac{12}{1} *\frac{4}{3} = \frac{12*4}{1*3}\\\\\frac{48}{3} \\16[/tex]

3) 9(y+3) = 18

Remember do PEMDAS in reverse.

Divide both sides by 9.

y+3 = 2

Subtract both sides by 3.

y = -1

Answer:

Well think about it, the key words there are more than and less than so if he traveled let's say from his house until the first city that's 100 miles for the first one and then they say that he traveled 10 miles less than the distance from the first city until the second city. The total distance is 280 because if you read the very last sentence it says that from the original distance from the first city is about 100 miles and then it says if the the distance from the second city to the third city was the same that means that the equation goes like this: (90*2)+100 and in order to get this correctly you must do P.E.M.D.A.S which is parenthesis, exponents, multiplying, dividing, adding and subtracting so there you go.

Step-by-step explanation:

Answer:

[tex]y = {(x + 3)}^{2} - 14[/tex]

Step-by-step explanation:

The original equation

[tex] f(x) = {x }^{2} + 6x - 5[/tex]

vertex form

[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]

solve for the x coordinate of the vertex, h

[tex]x = h = - \frac{b}{2a} = - \frac{6}{2(1)} = - \frac{6}{2} = - 3 \\ x = h = - 3[/tex]

substitute -3 back into the original equation to solve for y

[tex]y = { (- 3)}^{2} + 6( - 3) - 5 \\ y = 9 - 18 - 5 \\ y = 4 - 18 \\ y = k = - 14 [/tex]

substitute h and k values into the vertex form

a = 1 So we can omit it

[tex]y = {(x - ( - 3)}^{2} - 14 \\ y = {(x + 3)}^{2} - 14[/tex]
