I need to find the equation of the graphed line. ​

Answer:

Step-by-step explanation:

13d + 8 = -1

subtract 8 from both sides

13d = -9

d = -9/13

either keep it in fraction form or if you divide it out it is -0.6923

Answer:

the answer is c the one above d

Step-by-step explanation:

Answer:

The correct answer is C.

Step-by-step explanation:

Giving the following information:

Loan A: 9.265% nominal rate, compounded weekly

Loan B: 9.442% nominal rate, compounded monthly

Loan C: 9.719% nominal rate, compounded quarterly

To calculate the effective annual rate, we need to use the following formula:

Effective annual rate= [(1+i)^n] - 1

Loan A:

i= 0.09265/52= 0.001782

Effective annual rate= [(1.001782^52) - 1]

Effective annual rate= 0.097 = 9.7%

Loan B:

i= 0.09442/12= 0.007868

Effective annual rate= [(1.007868^12) - 1]

Effective annual rate= 0.0986 = 9.86%

Loan C:

i= 0.09719/4= 0.02439

Effective annual rate= [(1.02439^4) - 1]

Effective annual rate= 10.11%

Answer:

c

Answer:

77.6

Step-by-step explanation:

Given the data:

Weighting :

First exam = 20% ; second exam = 30% ; third exam = 50%

Scores :

First exam = 67 ; second exam = 84 ; third exam = 78

Weighted Average :

Σ(Weight * Score)

Σ[(0.2 * 67) + (0.3 * 84) + (0.5 * 78)]

13.4 + 25.2 + 39

= 77.6

Based on the weights assigned to these grades, Emily's weighted average in the class would be 77.6 marks.

= ∑ (Percentage of grade x Score in exam)

Solving gives:

= (20% x 67) + ( 30 % x 84) + (50% x 78)

= 13.4 + 25.2 + 39

= 77.6

Emily's weighted average is 77.6 marks.

Answer:

x=9

Step-by-step explanation:

So first subtract 8 on both Sides

3x+8-8=35-8

3x=27

Now divide 3 on both sides to isolate the variable x

x=9

So x=9

Answer:

so to do this you need to subtract 8 from 35 to get 27 now do 27 divide by 3 to get 9

3x+8=35

3x=35 - 8 = 27

3x = 27

3x divided by 27 = 9

Answer:

4.5m

Step-by-step explanation:

The set up is a right angles triangle

Height of the shed = opposite side = 6cm

Distance of the ladder from the shed = adjacent = 4.5m

Lenght of the ladder = Hypotenuse = x

Using pythegoras theorem to find the length of the ladder

hyp² = opp²+adj²

hyp² = 0.06² + 4.5²

hyp²= 0.0036+20.25

hyp² = 20.2536

hyp = √20.2536

hyp = 4.50m

Hence the length of the ladder is 4.5m

Step-by-step explanation:

If two equations have the same slopes and the same y-intercepts they are equivalent to each other

Here's why:

The formula for a linear equation is y= mx +b

b= y- intercept

m= slope

m and b are only variable that have to be replaced by a number for the equation to be complete

Therefore, when m and b (or the slope and the y-intercept)  of both equations are the same, the two equations are the same

The answer would be allrealnumbers, not nosolutions

Answer:

Positive

Step-by-step explanation:

There are a couple ways we can go about this.

First, we can see that as x increases, so does y, so that means its positive

For perspective, if x is the amount of time and y is the number of sales, we can see that the sales are going up and not going down or staying at the same place

If you wanna check your work on that, you can plot two points and find the slope using y1-y1/x1-x2 and the slope will be positive.

We can also use the process of elimination, we know it can't be zero because it's not a straight, horizontal line and we know its not undefined because it isn't a straight vertical line, so it's between negative and positive, and since the line is going up, that means that it's positive.

Answer:

Slope of XZ = -5/9

Slope of YZ  = 2/7

Slope of XY  = -7/2

Step-by-step explanation:

Slope is expressed as;

m = y2-y1/x2-x1

For XZ

X(−5, 5), and Z(4, 0)

Slope of XZ = 0-5/4-(-5)

Slope of XZ = -5/4+5

Slope of XZ = -5/9

For YZ

Y(−3, −2), and Z(4, 0).

Slope of YZ = 0-(-2)/4-(-3)

Slope of YZ = 2/4+3

Slope of YZ  = 2/7

For XY

X(−5, 5), Y(−3, −2)

Slope of XY = -2-5/-3-(-5)

Slope of XY = -7/-3+5

Slope of XY = -7/2

For two lines to be perpendicular, the product of their slope must be -1

Taking the product of XY and YZ

mXY * mYZ = -7/2 * 2/7

mXY * mYZ  = -1

since the product of mXY and mYZ is -1. this shows that line XY is perpendicular to YZ and showing that the triangle XYZ is right triangle

Answer:

Slope = -⁵/2

y-intercept = 6

Step-by-step explanation:

The equation, [tex] y = -\frac{5}{2}x + 6 [/tex], is given in the slope-intercept form, y = mx + b

Where:

m = slope

b = y-intercept

Therefore:

Slope of the equation = -⁵/2

y-intercept if the equation = 6

Answer: 41.4

Step-by-step explanation:

1243/30=41.4

$97 = (Original Price) - (35% of Original Price)

$97 = (Original Price) - (0.35 of Original Price)

$97 = (1 - 0.35) of (Original Price)

$97 = (0.65) of (Original Price)

$97 = 0.65 · (Original Price)

Divide each side by 0.65 .

$97/0.65 = Original Price

$149.23 = Original Price

Answer:

Balin could bench press 256 pounds.

Step-by-step explanation:

Jasper was able to bench press 224 pounds, which is 7/8 of x, which is the weight that Balin was able to bench press. So, mathematically:

[tex]\frac{7}{8}x = 224[/tex]

[tex]7x = 224*8[/tex]

[tex]x = \frac{224*8}{7} = 256[/tex]

Balin could bench press 256 pounds.
