Hi there!

Simplify the expression.
[tex]5(2x + 7) – 3(x + 5)[/tex]
[tex]=[/tex]
[tex]7x + 20[/tex]
❀Hope this helped you!❀
☽------------❀-------------☾
Step-by-step explanation:
let's start with 5(2x+7)
first you need to multiply 5 by 2x which = 10x
then multiple 5 by 7 which =35
That's 10x+35
The second part is -3(x+5)
-3 by x= -3x
-3 by 5= -15
So that becomes -3x-15
Put everything together and it's 10x+35-3x-15
First you do 35-15=20
Then 10x-3x=7x
the answer is 20+7x or 7x+20 (pretty sure it's kind of hard to do this typing out)

What happens to a point when it is reflected over the y-axis?
The coordinates stay the same.
The x-coordinate changes.
The y-coordinate changes.
Both coordinates change.
Answer:
the x-coordinates changes.
Step-by-step explanation:
i just done that question..
When a point is reflected over the y-axis then x-coordinate changes. so the correct option is B.
What is a reflection?A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.
When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If study it more, we will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Thus, if reflecting a point (x,y) along x axis, then its x abscissa will stay same but y ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
The correct option is B; the x-coordinate changes.

Answer:
Step-by-step explanation:
Given g(x)=5-6x, evaluate g(-5)
Answer:
35
Step-by-step explanation:
Since we want g(-5) we plug in -5 for x in the given equation.
g(x) = 5 - 6x
g(-5) = 5 - (6(-5))
g(-5) = 5 - (-30)
g(-5) = 5 + 30
g(5) = 35

In the previous scenario, 8 cookies cost 4 dollars. If the scenario was changed
So 6 cookies cost $4, would the unit rate be higher or lower? Explain.
Answer: Lower
Step-by-step explanation: It is lower because the unit rate is 8:4 and now the unit rate is 6:4
It would be higher because smaller numbers means more value per unit.
47 kg of potatoes cost $517. How many kilograms of
potatoes can you get with $154 ?
Step-by-step explanation:
47kg of potatoes is $517
That means 1kg of potatoes is 517/47 = $11.
$154 / $11 = 14.
Hence with $154, you can get 14 kilograms of potatoes.

Point M is the midpoint of AB. The coordinates of point A are (−8, 2) and the coordinates of M are (−3, 2). What are the coordinates of point B?
Answer:
B is (2, 2)

david used a scale 1 cm = 5 m to build a boat if the model is 8cm long , how long is the boat.
Answer:
40m
Step-by-step explanation:
8 times 5
The length of the boat is calculated using scale factor as 40 m.
What is Scale factor?The scale factor is a type of measurement which is used to increase or decrease the size of an object keeping its shape as the same. It can be determined by taking the ratio of the new and the original dimension of the object.
The scale factor for the given model can be calculated as,
Scale factor = Dimension of boat ÷ Dimension of model
= 5 ÷ 1
= 5
Now, the new length of the boat for 8 cm length of the model is given as,
New length = Scale factor × Length of model
= 5 × 8
= 40 m.
Hence, the length of the boat is given as 40m.

"Some men must put the wrong answer down, what makes them a good person is not whether or not their answer was right, it was that they shared the right answer to Brainly." -Me 2020
Answer:
When a line of reflection coincides with a line of symmetry, the polygon maps onto itself. The position of the line of symmetry depends on the number of sides. For regular polygons with an even number of sides, lines of symmetry are the perpendicular bisectors of the opposite sides and the angle bisectors of opposite vertices. However, the symmetry of regular polygons with an odd number of sides does not allow lines of symmetry to connect the opposite pairs of vertices, so they have symmetry only along the perpendicular bisectors.

If BD bisects
ABC, ABD = 2x + 3, and
DBC = 3x - 13, find ABD.
Answer:
35
Step-by-step explanation:
Since its an angle bisector, both angles would be equal to each other.
3x-13=2x+3
Now you need to get x alone.
Subtract 2x from each side.
x-13=3
Still need x alone so add 13 to each side (since it negative addition)
x=16
You have x, but you need ABD
Plug 16 in for x
2(16)+3
32+3
35

3.9x + 1.4 = 17 what is the steps
Answer:
[tex]x=4[/tex]
Step-by-step explanation:
[tex]3.9x + 1.4 = 17[/tex]
Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.
[tex]3.9x*10+1.4*10=17*10[/tex]
[tex]39x+14=170[/tex]
Subtract 14 from both sides:
[tex]39x+14-14=170-14[/tex]
[tex]39x=156[/tex]
Divide both sides by 39:
[tex]\frac{39x}{39}=\frac{156}{39}[/tex]
