How many solutions are there to the equation below?
7(x + 2) = 7x-10
A. Infinitely many
В. 0
C. 1

Answer: y = 4x-23

Step-by-step explanation:  I'm assuming the question asks:  "A line passes through the point (4, - 7) and has a slope of 4."  I had difficulty understanding the format of the question.  Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We can start with y = 4x + b, since we are given the slope.  We can then use the given point (4,-7) to find b, since this point is on the line and thus satisfies the equation.

y = 4x + b

-7 = 4(4) + b

-7 = 16 + b

b = - 23

The equation is y = 4x-23

Answer:

b

Step-by-step explanation:

Answer:

-1

Step-by-step explanation:

Let's take two points on the line- (0,2) and (2,0).

To find the slope:

[tex]m = \frac{y_2 - y_1}{x_2-x_1}\\m = \frac{0 - 2}{2-0}\\m = \frac{-2}{2}\\m = -1[/tex]

The slope is -1.

Answer:

y = -4x - 14

Step-by-step explanation:

plug (x, y) in to the y = mx+ b formula, and plug -4 in as m

Answer:

B

Step-by-step explanation:

going down on the right

Answer:

B

Step-by-step explanation:

Aline with zero slope is a horizontal line parallel to the x- axis

A line with undefined slope is a vertical line parallel to the y- axis

A line sloping upwards from left to right has a positive slope

A line sloping downwards from left to right has a negative slope.

The line shown slopes downwards from left to right and has a negative slope

Answer:

4x + x = 145,                            x=29 (shorter piece)

5x=145

x=145/5 = 29

Step-by-step explanation:

Answer:

Descending order:

14560g

13.6kg

13.25kg

12000g

a.) [tex]\frac{18}{5}[/tex]

b.) [tex]\frac{25}{2}[/tex]

Step-by-step explanation:

To find the difference between kg or g, either divide kg by 100 to convert to g, or multiply g by 1000 to convert to kg.

If we were to put everything into g:

14560g

13600g

13250g

12000g

See how they are still in the correct order?

If we were to put everything into kg:

14.56kg

13.6kg

13.25kg

12kg

Still in descending order!

___________________

Now to find out how to put the decimals into fractions:

Multiply by 10 (since there is only 1 digit behind the decimal, for every digit behind the decimal you multiply by another factor of 10, so if you have 2.55 you multiply by 100)

Following this we get:

36

125

Now divide by the same factor (10), we can't change the value of the number, just the way they look!

[tex]\frac{36}{100}[/tex]

[tex]\frac{125}{10}[/tex]

All that's left is it reduce!

[tex]\frac{18}{5}[/tex]

[tex]\frac{25}{2}[/tex]

And as you can see, we are back to the number I had put in the solution!

Answer:

Answer:

The construct a line through P that is  perpendicular to the line.

Step-by-step explanation:

Given that,

Construct a line through P that is  perpendicular to the line.

We need to construct a perpendicular line P

Using given data

We draw an arc across the line on each side of the point P.

Now, from each arc on the line, draw another arc on the opposite side of the line from the point P.

The  point P to the point where the arcs intersect Q.

Hence, The construct a line through P that is  perpendicular to the line.

Answer: 2 2/3 gallons left

explanation:

6 1/2 = 6 3/6

6 3/6 - 3 5/6 = 2 2/3

proof: 2 2/3 + 3 5/6 = 6 3/6

Answer:

a x=-3

Step-by-step explanation:

The equation x = 3 represents a vertical line and not a mapping from values of x to values of y. For one thing, it fails the vertical line test for functions at the value x = 3.

Answer:

13.5 lb/in^2

Step-by-step explanation:

8ft = 3.6 lb

30ft= ?

8ft÷30ft = 3.75

this means 8ft goes into 30ft 3.75 times

3.6lb× 3.75=13.5lb/in^2

you times the pressure of 8ft by 3.75 to find how much pressure there is at 30ft

Answer:

y = -3x + 5

Step-by-step explanation:

y = -3x + b

-1 = -3(2) + b

-1 = -6 + b

5 = b

Answer:

x=40

y=40

Step-by-step explanation:

hlo there!

as the given is 90 ° in fig;

90+50+x= 180°( sum of angle of traingle)

x=180-140

x=40°

as there is alternate angle.

lets suppose the alternate angle of x is z

z=40°

now'

40 + 100+ y=180°( sum of angleof traingle)

y=40°

hope it helps!

Answer:

(y²)³ = y⁶

Step-by-step explanation:

The power of a power rule is generally shows expressions where a power is being raised by another power. In such expressions, the exponents are multiplied together and the base is kept the same, like:

[tex] \qquad \qquad\boxed{ \sf{ { {(x}^{m}) }^{n} = {x}^{mn} }}[/tex]

In order to write the expression (y²)³ in the form of yⁿ, you may use this rule (power of a power rule) to obtain the answer.

[tex]\qquad \quad \sf{ { {(y}^{2}) }^{3} = {y}^{2(3)} = \pmb {\red{ {y}^{6}}}}[/tex]

Answer:

the is c because the answer

The correct answer is B: {2, 6, 8}.

The set of first components (x-coordinates) in the ordered pairs is the domain of the relation: {-1, 3, 5}.

The set of second components (y-coordinates) is the range of the relation. The range of the given problem is the set of second components (on the right): {2, 6, 8}.

Therefore, the correct value is B: {2, 6, 8}.
