Can Anyone Help Me Please Thank You

Answers

Answer 1

Answer:

The first option

Step-by-step explanation:

Because when you multiply the first equation by 2, it sets the -x to -2x which helps cancel the variable out allowing you to easily solve the system of equations.

Answer 2
The answer is the first option because when you multiply the first equation by 2, you can cancel the x’s because when -2+2 is added it equals 0

If the line containing the points (-2,10) and (7, 4) is dilated by a factor of 2, what is the
slope of the image?
ASAPPP NUMBER 2

Answers

Answer: Slope = -2/3

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

Explanation:

Let's compute the slope of the line through the two original points

m = (y2-y1)/(x2-x1)

m = (4-10)/(7-(-2))

m = (4-10)/(7+2)

m = -6/9

m = (-2*3)/(3*3)

m = -2/3

The slope is -2/3

-------------

Now apply the scale factor.

We'll multiply each coordinate of each point by 2

(-2,10) becomes (-4,20) after multiplying each coordinate by 2

(7,4) becomes (14,8) after multiplying each coordinate by 2

Let's find the slope of the line through (-4,20) and (14,8)

m = (y2-y1)/(x2-x1)

m = (8-20)/(14-(-4))

m = (8-20)/(14+4)

m = -12/18

m = (-2*6)/(3*6)

m = -2/3

We get the same slope. This isn't a coincidence. Dilating a set of points will preserve the slope of the line through those points.

If A and B are the two original points, and A' and B' are the dilated counterparts, then the slope of line AB is the same as the slope of line A'B'.

The scale factor doesn't affect the answer.

How to construct the inscribed circle of a triangle?

Inscribed circle of a triangle is the largest circle, contained in the triangle.

Steps to construct the inscribed circle of a triangle-

Step 1-Bisect one of the angle of the triangle.

Step 2-Now bisect the another angle of the triangle.

Step 3-The crossing point of both the angle bisects is the in center of the triangle and center of the required circle.

Step 4- Draw a perpendicular from this center to one of the side of the triangle.

Step 5-Now draw a circle using the compass with the in center as a center of the and radius equal to the perpendicular from the in center to one of the side.  

Thus to construct the inscribed circle of a triangle the in-center is required. the option 3 is the correct option.

Answer:

[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex]

Step-by-step explanation:

We know that [tex]x[/tex] and [tex]y[/tex] are directly proportional. Therefore, using the given information, we can set up the following proportion:

[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]

Solving for [tex]y[/tex], we get:

[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]

[tex]12*y=6.5*4[/tex] (Cross-Products Property)

[tex]12y=26[/tex] (Simplify)

[tex]\frac{12y}{12} =\frac{26}{12}[/tex] (Divide both sides of the equation by [tex]12[/tex] to get rid of [tex]y[/tex]'s coefficient)

[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex] (Simplify)

Answer:

c) 126 inches of the answer

Answer:

C. 126 inches²

Step-by-step explanation:

To find the area of a trapezoid multiply the sum of the two bases (12 + 16) and the height divide by 2 (9 / 2) by each other

(12 + 16)9/2

Add 12 and 16 to get 28.

28(9/2)

Multiply 28 by 9 to get 252.

252/2

Divide 252 by 2 to get 126.

The area of the trapezoid is 126 inches².

Can anyone solve this for me?

Answers

Answer:

4x + 3 = 11

4x = 11 - 3

4x = 8

x = 8 ÷ 4

x = 2

3x - 5 = 7

3x = 7 + 5

3x = 12

x = 12 ÷ 3

x = 4

8x - 5 = -37

8x = -37 + 5

8x = -32

x = -32 ÷ 8

x = -4

7(x - 3) = 21

7x - 21 = 21

7x = 21 + 21

7x = 42

x = 42 ÷ 7

x = 6

They subtracted 5 on both sides of the equation. They were suppose to add 5 on both sides of the equation for it to cancel out each other. If you need any further explanation, please ask me :)

Correct version:

5y + (-5) = 10

       +5     +5    add 5 to both sides, 5's will cancel out on left side.

___________

5y     15

__ = __        divide 5 on both sides, 5's will cancel out on left side.

5      5

y = 3, final answer

Answer:

its the first part the (-5) -5  is supposed to be (-5) +5

Step-by-step explanation:

so the equation is 5y=15

then you divide 5y/5 is y so then you 15/5 is 3

so the answer is y=3
