(-2,4) (8,10) slope intercept form

Mathematics
1 answer:
kherson [118]3 years ago
3 0

Answer:

Step-by-step explanation:

1) Use the given coordinate points to find the slope

m=\frac{10-4}{8-(-2)}  m=\frac{3}{5}

2) plug the slope into slope-intercept form

y=\frac{3}{5}x+b

3) choose one point to use to plug into the equation to solve for b

4=\frac{3}{5}(-2)+b

4) solve for b.

b=\frac{26}{3}

5) substitute the value for b into equation from step 2

y=\frac{3}{5}x+\frac{26}{3}

which of the following would be a line of reflection that would map ABCD onto itself? A(-3,0) B(-3,2) C(-1,2) D(-1,0)
Aleksandr-060686 [28]

The line of reflection that would map ABCD onto itself is the line y = x + 3

<h3>What is a transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>translation, rotation, reflection and dilation.</em>

Dilation is the increase or decrease in the size of a figure.

The equation of the line passing through A(-3, 0) and C(-1, 2) is:

y-0 = [(2-0)/(-1-(-3))](x - (-3)]

y = x + 3

The line of reflection that would map ABCD onto itself is the line passing through AC which is y = x + 3

zodwa needs R450550.00 to buy a house, the bank approved her loan for the full amount at an interest rate of 25% per year, compo
adell [148]

Answer:

I'll setup the problem and leave the computation to you

Step-by-step explanation:

The equation to calculate fixed payments

P =  \frac{r(PV)}{1- {(1 + r)}^{ - n} }

P= payments

r = interest rate for the period (which is a quarter )

PV = present value (or the amount borrowed)

n = number of periods

r = .25/4 (4 months = quarter of a year)

n = 4*10

PV = R450550.00

A statistics teacher started class one day by drawing the names of 10 students out of a hat and asked them to do as many pushups
HACTEHA [7]

Answer:  b. 8.56 to 21.44

Step-by-step explanation:

Let  \mu be the  mean number of pushups that can be done.

As per given , we have

Sample size : n= 10

Degree of freedom = n-1=9

Sample mean : \overline{x}=15

Sample standard deviation : s=9

Significance level : α=1-0.95=0.05

From t- distribution table ,

Critical two -tailed t-value for α=0.05 and df = 9 is

t_{\alpha/2, 9}=t_{0.025,9}=2.2622

Confidence interval for \mu is given by :-

\overline{x}\pm t*\dfrac{s}{\sqrt{n}}

=15\pm (2.2622)\dfrac{9}{\sqrt{10}}\\\\\approx 15\pm 6.44=(15-6.44,\ 15+6.44)\\\\=(8.56,\ 21.44)

Hence, the  95% confidence interval for the true mean number of pushups that can be done is 8.56 to 21.44.

The strip below is divided into 10 equal parts. Fill in the missing fractions and percentages.Note that your fractions don't nee
boyakko [2]

Answer:

1. First box, the missing fraction = 1/10

2. For the 2nd box

a. The missing fraction = 3/10

b. Percentage = 30%

3. For 7/10

Percentage = 70%

Step-by-step explanation:

From the question given above, the following data were obtained:

The strip is divided into 10 equal parts.

1. For the first box:

The missing fraction = 1/10

2. For the 2nd box

a. The missing fraction = 3/10

b. Percentage = 3/10 × 100 = 30%

3. For 7/10

Percentage = 7/10 × 100 = 70%
