Put ur first point at -7... Then rise 1 run 1 and keep going.

hope it helps comment if you have any questions and have an amazing day

The graph of y = x -7 is given below.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Given:

The linear equation,

y = x -7.

Comparing with the slope-intercept form:

y = mx + b, where m is the slope and b is the y-intercept.

m = 1 and b = -7.

That means, when we draw the graph, we can rise 1 unit and run 1 unit.

Substitute the assumed value of x to get the value of y.

Put x = 0, we get,

y = -7.

And put x = 7, then y = 0

That means, (7,0) and (-7, 0) are the intercepting coordinates.

And the graph is given in the attached image.

Therefore, graph of y = x -7 is given.

Solving the modular arithmetic will result to

The term modular arithmetic is the arithmetic that works with whole numbers in a such that, following division by a modulus, all numbers are replaced by their remainders.

Solving the modular arithmetic: 2 + n = 0 (mod 6)

2 + n = 0 (mod 6)

n = -2

Solving the modular arithmetic: 2 + (3 + n) = 1 (mod 6):

2 + (3 + n) = 1 (mod 6)

5 + n = 1 (mod 6)

n = 1 - 5

n = -4

When subtracting a negative it becomes a positive

Answer:

$1,349.8

Step-by-step explanation:

Using the formula given:

A=Pe^rt, where

A= ending amount

P= beginning amount

e= Euler’s number that is approximately 2.718

r= rate: 3%=0.03

t= time: 10 years

A= $1,000*(e^0.03*10)

A= $1,000*(e^0.3)

A= $1,349.8

According to this, the answer is that the balance after 10 years is $1,349.8.

Answer:

b ≈ 29.7 units

Step-by-step explanation:

Because we don't know whether this is a right triangle, but have an angle sandwiched between two sides, we can use the law of cosines to find b.

The law of cosines is given by the following formula:

(1.) a^2 = b^2 + c^2 - 2bc * cos(A)

(2.) b^2 = a^2 + c^2 -2ac * cos(B)

(3.) c^2 = a^2 + b^2 - 2ab * cos(C)

Because angle B is sandwiched between a and c, we can use formula 2 by plugging in 45 for a, 23 for c, and 36 for B.

Step 1: Plug everything in and simplify:

b^2 = a^2 + c^2 -2ac * cos(B)

b^2 = 45^2 + 23^2 - 2(45)(23) * cos(36)

b^2 = 2025 + 529 - 2070 * cos(36)

b^2 = 2554 - 2070 * cos(36)

b^2 = 879.3348216

Step 2:  Take the square root of both sides to find b and then round to the nearest tenth:

√b^2 = ± √879.3348216

b = 29.65358025

b = 29.7

Although taking the square root of number gives you a positive and negative number since squaring both a positive and negative number give you a positive answer (e.g., 2 * 2 = 4 and -2 * -2 = 4), we can only use the positive answer since you can't have a negative measure.  Thus, b is approximately 29.7 units.

The integral is ∫ x sec x tan x dx. We can solve it using integration by parts xln|sec(x) + tan(x)| - x + C

We have u = x, dv = sec(x)tan(x)dx, du = dx, and v = ln|sec(x) + tan(x)|.

The integral is then

Integrating the second part we get:

xln|sec(x) + tan(x)| - x + C

The integral is ∫ x sec x tan x dx. We can solve it using integration by parts. We let u = x and dv = sec(x)tan(x)dx. Then, du = dx and v = ln|sec(x) + tan(x)|. So, the integral becomes xln|sec(x) + tan(x)| - ∫ ln|sec(x) + tan(x)| dx. We can integrate the second part to get xln|sec(x) + tan(x)| - x + C.

Step-by-step explanation:

The y-intercept of Function A is 1 unit greater than the y-intercept of Function B. Then the correct option is C.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Some values of linear functions A and B are shown in the table and graph.

Function A

0       1

1      1.25

2       1.5

3      1.75

4        2

The function A is passing through (0, 1), then the equation of the line will be

1 = 0m + c

c = 1

Then the equation of the function A will be y = mx + 1.

From, the graph, it is clear that the y-intercept of Function A is 1 unit greater than the y-intercept of Function B.

Then the correct option is C.

There are 56 possible ways to make a selection of coins so that the value is at least 25 cents.

The total number of possible ways to make a selection of coins so that the value is at least 25 cents is calculated using the formula:

# of ways = (n+r-1Cr-1)

Where n is the number of coin denominations available and r is the number of coins needed to make the selection.

In this case, n = 5 (1 cent, 5 cents, 10 cents, 25 cents, 50 cents) and r = 4. Therefore, the number of ways to make a selection of coins so that the value is at least 25 cents is calculated as:

of ways = (5+4-1C4-1)

of ways = (8C3)

of ways = 56
