Answer:

Option A: y-9=2(x-1)

Step-by-step explanation:

Notice that the answer choices are in point-slope form which is y-y1=m(x-x1)

The slope, m, is (9-3)/(1-(-2))=6/(1+2)=6/3=2, but that's given anyway.

Option A would be right because y1=9 and x1=1 which is where the line crosses through (1,9)

B is not right because that would suggest the line crosses (2,3) as y1=3 and x1=2, but it actually crosses (-2,3) so it should've been y-3=2(x+2)

C and D are wrong because the points aren't crossed through

Answer:

The equation in the slope-intercept form will be:

[tex]y=2x+10[/tex]

Step-by-step explanation:

Given the points

Finding the slope between two points

[tex]\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(-4,\:2\right)[/tex]

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{2-4}{-4-\left(-3\right)}[/tex]

[tex]m=2[/tex]

As the point-slope form  of the line equation is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

putting the values m=2 and the point (-3, 4)

[tex]y-4=2\left(x-\left(-3\right)\right)[/tex]

[tex]y-4=2\left(x+3\right)[/tex]

Writing the equation in slope-intercept form

[tex]y=mx+b[/tex]

where m is the slope, and b is the y-intercept

so the equation becomes

[tex]y-4=2\left(x+3\right)[/tex]

add 4 to both sides

[tex]y-4+4=2\left(x+3\right)+4[/tex]

[tex]y=2x+10[/tex]

Therefore, the equation in the slope-intercept form will be:

[tex]y=2x+10[/tex]

Answer:

250%

Step-by-step explanation:

For this equation we have to use the percent composition formula. It is as follows:

[tex]\frac{part}{whole} *100 = percent[/tex]

Now, we plug in the numbers given in the equation. 125 being the part and 50 being the whole.

[tex]\frac{125}{50} *100 = 250[/tex]

Therefore, 125 is 250% of 50.

Hope this helps!!

The percentage of 125 in whole quantity 50 is, 250%

Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".

To find what percentage 125 is of 50, we first need to convert the ratio of 125 to 50 into a decimal and then convert the decimal into a percentage.

The ratio of 125 to 50 can be expressed as a fraction: 125/50. We can convert this fraction to a decimal by dividing the numerator by the denominator:

⇒ 125/50

⇒ 2.5

Next, we convert the decimal to a percentage by multiplying it by 100 and adding the percent symbol:

⇒ 2.5 x 100

⇒ 250%

So, 125 is 250% of 50. This means that 125 is equal to 250% of the value of 50.

Answer:

2. m<6 = ⅛m<4 ------- Given

3. m<6 + m<4 = 180 ------- Supplementary Angles

5. m<6 = 20; m<4 = 160 ----- Algebra

Step-by-step explanation:

Required

Fill in the gaps

1. a || b ------ Given

From the question, we understand that m<6 is ⅛ of m<4. This answers (2) as follows:

2. m<6 = ⅛m<4 ------- Given

From the attached figure, m<6 and m<4 are supplementary angles and they add up to 180. So:

3. m<6 + m<4 = 180 ------- Supplementary Angles

In (2): m<6 = ⅛m<4

Multiply both sides by 8

8 * m<6 = 8 * ⅛m<4

8m<6 = m<4

So, substitute 8m<6 for m<4 in (3). This gives (4)

4. m<6 + 8<m6 = 180 ---- Substitution

Solve (4) algebraically,

9m<6 = 180

Multiply both sides by ⅑

⅑ * 9m<6 = ⅑ * 180

m<6 = 20

Recall that m<4 = 8m<6

So:

m<4 = 8 * 20

m<4 = 160

Hence, (5) is

5. m<6 = 20; m<4 = 160 ----- Algebra

Answer:

Step-by-step explanation: There are different methods to solve this, but I chose to change these into decimals- 1.8 and .20, to make it easier. Since miles per hour is speed, and speed is distance divided by time, all you have to do is fill in the blanks.

Since 1.8 / .20= 9, the answer is 9 miles per hour.

To take it a step farther, you could multiply this by any number of hours, or convert it to minutes. For example, to figure out how far they'd get in 10 minutes, I could divide the unit rate by 60, since there are 60 minutes in an hour, and get 0.15. So, in 10 minutes, they'd get 0.15 miles away.
