I triangle ABC is dilated by a scale factor of 3 with a center of (2.1). what is the location of A?

Answer:

D. y=4x-1

Step-by-step explanation:

y=mx+b (This is the slope intercept formula) The M(X) represents the slope and the B represents the y intercept.

y=4x-1

Answer:

d. y = 4x -1

Step-by-step explanation:

y = mx + b

  m= 4

  b= -1

y = (4)x + (-1)

y = 4x - 1

can i get brainliest please?

Answer:

See Below.

Step-by-step explanation:

We know that r and s are parallel. This means that p and q are transversals.

We also know that ∠1 and ∠4 are supplementary.

And we want to prove that p is parallel to q.

  Statements:                                 Reasons:

1) [tex]\bf{r\parallel s[/tex]                                              Given

2) [tex]\angle 1 \text{ and }\angle 4\text{ are supplementary}[/tex]     Given

3) [tex]\angle 1\text{ and } \angle 5 \text{ are supplementary}[/tex]     Consecutive (Interior) Angles Theorem

4) [tex]\bf{\angle 5\cong \angle 4}[/tex]                                      Congruent Supplements Theorem

5) [tex]p\parallel q[/tex]                                           Corresponding Angles Theorem Converse

And we are done!

Answer:

the other side has an 90° angle , it must be an acute triangle

Step-by-step explanation:

a triangle has a total angle of 180°

So if one side has an angle of 60° and the other has an angle of 30°, the other side must be the substraction of both angles to the 180° sum

180° - 60° - 30° = 90°

Answer: The longest side is twice as long as the shortest side.

Answer:

14 because there are 14 numbers in the equation :)

Answer:

x-int: (-250, 0) y-int: (100, 0)

Answer:

x = 75° and y = 105°

Step-by-step explanation:

In the given figure

∵ The angle of measure (180 - x) and the angle of measure y are

   corresponding angles

∵ Corresponding angles are equal in measures

→ Equate their measures

∴ 180 - x = y ⇒ (1)

∵ The angle of measure y and the angle of measure 75° are linear angles

∵ The sum of the measures of the linear angles is 180°

→ Add their measures and equate the sum by 180°

∴ y + 75 = 180

→ Subtract 75 from both sides to find y

∵ y + 75 - 75 = 180 - 75

∴ y = 105°

→ Substitute the value of y in (1)

∵ 180 - x = 105

→ Subtract 180 from both sides

∵ 180 - 180 - x = 105 - 180

∴ - x = - 75

∵ Divide both sides by -1 to find x

∴ x = 75°

Answer:

Idek but B and C are parallel

Step-by-step explanation:

You would multiply top and bottom by [tex]\sqrt{3}[/tex] to go from [tex]\frac{1}{\sqrt{3}}[/tex] to [tex]\frac{\sqrt{3}}{3}[/tex]

Multiplying a square root by itself is the same as squaring the value.

So, [tex]\sqrt{x}*\sqrt{x} = (\sqrt{x})^2 = x, \ \ \text{ when } x \ge 0[/tex]

Which is why we're able to get rid of the square root in the denominator. The square root and squaring operation effectively cancel each other out.

Answer:

f(2) = 7

Step-by-step explanation:

Solve for f(-2) in f(x) = 3x + 1

x = -2

Plug in -2 for x in the equation:

f(2) = 3(2) + 1

Remember to follow PEMDAS. First, solve the multiplication, then add:

3 * 2 = 6

6 + 1 = 7

f(2) = 7 is your answer.

Answer:

I know the sales tax is .16 here in Texas. I found out whenever me or my mom would go shopping. I would look at the tax at the bottom of the recipt or do the math. Find the sum of all the gorceries without tax and then subtract it by the total amount of money of the groceries with tax. Then divide that by the amount of groceries we bought.

Step-by-step explanation:

Answer:

y=-1x-6

Step-by-step explanation:

the slope is -1

use y=mx+b

Plug  the point into y=mx+b, -7=-1(1)+b

-7=-1+b

add 1 both sides the y- intercept is b=-6

Answer:

width: 7 length: 18

Step-by-step explanation:

they tell us the length is 2 times the width plus 4 more so the equation for one of the lengths is

2x + 4, where 'x' is the value of one width. but, because there are two sides for each the length and the width, the final equation will be:

2(2x + 4) + 2(x) = 50

then simplify and solve for 'x'

Answer: 340$$$

Step-by-step explanation:

Basically you divide 680 by 2 cause 2 is half which is the same as 50% so its 340
