Answer:

A(-4, 1)

Step-by-step explanation:

The parts being equal means ...

A - P = P - B

A = 2P - B . . . . . . . . useful to remember for P being the midpoint of AB

A = 2(-1, 4) -(2, 7) = (-2-2, 8-7)

A = (-4, 1)

What is x? and what is z? A. 84 B. 92 C. 96 D. 109

Svetradugi [14.3K]

Step-by-step explanation:

180 = 55 + 41 + y (Angles in a triangle)

y = 180-(55+41)

y = 84

y+ z = 180 (Angles on a line)

z = 180 - y

z = 180 - 84

z = 96

The lines are parallel.

The angle opposite x is 109 because the are corresponding.

x is 109 (vertically opposite angles)

For how many integers will 3x + 4 be greater than 44 and less than 100?

N76 [4]

The integer values in 3x + 4 be greater than 44 and less

than 100 is 17

<h3>Solving the inequality</h3>

Given data

3x + 4 > 44

3x + 4 < 100

solution

3x + 4 > 44

3x > 44 - 4

3x > 40

x > 13.333

for integer greater than 40 we have

x = 14, 15, 16,.....

3x + 4 < 100

3x < 100 - 4

3x < 96

x < 32 hence x is from 31 down

x = 31, 30, 29,....

so this is x takes value from 14 to 31 which is 17 values

hence the integer values in 3x + 4 be greater than 44 and less

than 100 is 17

Jason started with d dollars in his piggy bank. One week late, Jason doubled the amount in his piggy bank. Another week later, j

elena55 [62]

Given, Jason had an amount of $d in the piggy bank.

After one week, Jason doubled the amount in the piggy bank.

So, after one week the amount in the piggy bank = $ $(2)(d)$ = $(2d)

Another week later, Jason added $20 in the piggy bank.

So after another week, the total amount in the piggy bank = $ $(2d+20)$

Given, that time the piggy bank had $50 in it.

So we can write the equation as,

$2d+20 = 50$

To find the value of d, we will move 20 to the right side by subtracting it from both sides. We will get,

$2d+20-20 = 50 - 20$

$2d = 50 -20$

$2d = 30$

Now to find d, we will move 2 to the right side by dividing it to both sides. We will get,

$\frac{2d}{2}=\frac{30}{2}$

$d = 15$

We have got the required answer.

The value of d = $15.
