Answer:

slope is 0

Step-by-step explanation:

to find slope y2 - y1 / x2 - x1

(6, -2) and (12, -2)

-2 - (-2) / 12 - 6

= -2 + 2/6

= 0/6

= 0

Answer:

slope is 0

Step-by-step explanation:

Answer: Part A : slope = 20/1 -8/1  12/4 =3  Part B: The y-intercept is 5

Step-by-step explanation: I just did this with my teacher..Hope this helps! ( The numbers in bold are the answers)

The slope of the graph is 3 and the y intercept is 5.

A linear equation is in the form:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept

Let y represent the height of the tree after x years.

The line passes through the point (0, 5) and (3, 14). Hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-5=\frac{14-5}{3-0} (x-0)\\\\y=3x+5[/tex]

Therefore the slope of the graph is 3 and the y intercept is 5.

2(−x+y=−2)

1(2x−3y=4)

Becomes:

−2x+2y=−4

2x−3y=4

Add these equations to eliminate x:

−y=0

Then solve−y=0for y:

−y=0

−y/-1 = 0/-1 (Divide both sides by -1)

y=0

Step-by-step explanation:

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

−x+y=−2

Substitute 0 for y in −x+y=−2:

−x+0=−2

−x=−2(Simplify both sides of the equation)

−x/-1 = -2/-2 (Divide both sides by -1)

x=2

Answer:

x=2 and y=0

Answer: x=y+2

Step-by-step explanation:

Step 1: Add -y to both sides.

−x+y+−y=−2+−y

−x=−y−2

Step 2: Divide both sides by -1.

-x/-1 = -y - 2/-1

asnwer: x=y+2

Answer: x = 3/2y + 2

2x−3y=4

Step 1: Add 3y to both sides.

2x−3y+3y=4+3y

2x=3y+4

Step 2: Divide both sides by 2.

2x/2 = 3y + 4/2

answer: x = 3/2y + 2

Answer:

B.) is the answer bro I got the same test bro like just trust me and give me 5 start and like and give a heart

Answer:

Step-by-step explanation:

His functions are:

h(x)= $350

s(x)=(1.04))^x-1

To find total amount of money in Tommy's account using the functions above, we substitute the first function x= $350 in the second function

So, we can say that the new function represents the interest received by

Tommy with initial saving $350.

A function is a group of statements that together perform a task.

Given that Tommy got $350 as the gift which he saves.

So, the amount saved is given by the function is [tex]h(x)=350....(1)[/tex]

Also, the interest by the saving bank account is given by,

[tex]s(x)=(1.04)^{x-1}....(2)[/tex]

Comparing equations (1) and (2)  we get a new function as,

[tex]g(x)=350(1.04)^{x-1}[/tex]

The function gives the value [tex]h(x)=350[/tex] when [tex]x=0[/tex] and the amount is increasing by the interest.

Answer:

56

Step-by-step explanation:

The function can be graphed to demonstrate this further. On the graph where f(x)=0, the curve is just the x-axis, which always has the same y-value of 0.

Domaine:The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Given the function f(x)=0,

since this is a constant function (that is, for any value of x, f(x)=0, the limit of the function as x→a, where a is any real number, is equal to 0.

More specifically, as a constant function,f(x) maintains the same value for any x. f(1)=f(2)=f(π)=f(e)=f(−(1258567)/(44))=0. Further, as a constant function, f(x) is by definition continuous throughout its domain. Note, however, that if one arrives at a constant function via division or multiplication of non-constant functions (for example, (8x)/(x), there will still exist a discontinuity where the original denominator was0).

Graphing the function will further prove this point. On the graph f(x)=0, the curve is simply the x-axis, which maintains a constant y-value of 0 no matter the x-value.

kay

Step-by-step explanation:

Answer:

Step-by-step explanation:

The equation of the line in point slope form is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is a point on the line

Get the slope;

Given the points (-1,3) and (1, 7)

m = y2-y1/x2-x1

m = 7-3/1+1

m = 4/2

m = 2

Substitute the point m = 2 and the point (-1, 3) into the formula above as shown;

y - y0 = m(x-x0)

y - 3 = 2(x-(-1))

y - 3 = 2(x+1)

Hence the required equation is y - 3 = 2(x+1)

Answer:

18

Step-by-step explanation:

Answer:

A. 8 , 3(4)-4= 8

B. -2 , 5-(-3)= -2

C. -18 , 5-4+3(-5)-4 = -18

Figure ABCDE is similar to figure FGHIJ and because corresponding sides have same ratio.

Similar triangles are triangles that have the same shape, but their sizes may vary.

In figure ABCDE vertices A,B,C,D,E are given so we can find their sides by applying distance formula:

D=√((x2 - x1)² + (y2 - y1)²)

With the help of this formula we can find AB;

AB = √(-1 - (-3))² + (3 - 1)²)

AB = √((-1 + 3)² + (2)²)

AB = √((2)² + (2)²)

AB = √(4 + 4)

AB = √8

AB = (√2*2) * 2

AB = 2√2

Likewise, we can find the remaining sides as;

BC = 4, CD = √10, DE = √10 and EA = 2√2

FG = √2, GH = 2,HI = 1.58114, IJ = 1.58114 and JF = √2

When the two figures are similar then the ratios of their corresponding sides are equal.

Thus, we have that;

AB/FG = BC/GH = CD/HI = DE/IJ = EA/JF

Therefore, we conclude that figure ABCDE is similar to figure FGHIJ and because corresponding sides have same ratio.

Answer:

30

Step-by-step explanation:

If Line A is parallel to Line B, then 2x+50+5x-80 = 180. This is because 2x+50 is an alternate interior angle with the supplement of 5x-80, therefore the supplement of 5x-80 is also 2x+50. Supplementary angles add up to 180°.

2x + 50 + 5x - 80 = 180 --> Combine like terms

7x - 30 = 180 --> Add 30 to both sides

7x = 210 --> Divide both sides by 7

x = 30

We can check our answer by plugging 30 in for x back into our original equation.

2(30) + 50 + 5(30) - 80 = 180

60 + 50 + 150 - 80 = 180

110 + 150 - 80 = 180

260 - 80 = 180

180 = 180

Therefore x = 30.

Answer:

3 degrees

Step-by-step explanation:

-8, -7 -6,-5,-4,-3,-2,-1,0, 1,2 3

If you count 11 spaces to the right on a number line, starting at -8, you will land at 3 degrees.

=========================================================

Explanation:

Think of the +11 as +8+3

Draw a vertical number line. Start at -8 on that number line. Then move up 8 units to arrive at 0. Afterward move the remaining 3 units to get to 3 on the number line. We've moved up a total of 8+3 = 11 degrees.

In other words, starting at -8 and moving up 11 units will have us arrive at 3

This visually shows -8+11 = 3
