Pls help i dont understand :( will give Brainliest + 25 Points
Answer:
A
Step-by-step explanation:
plug the points into the slope formula
slope = (y2 - y1)/(x2 - x1) Then you get the slope of -0.5
(5 - -1))/(-6-6)
6/-12
-0.5
Plug a point in to the equation of y = -0.5x + b
-1 = -0.5(6) +b
2 = b

7t - 4 = 10t + 14 HURRY PLEASE
Answer:
7t-4=10t+14
7t-10t=14+4
-3t=18
-3t/3=18/-3
t=-6
Answer:
Pretty sure it's t = -6
Step-by-step explanation:
7t - 4 = 10t + 14
7t -10t = 14 + 4
-3t = 18
t = -6
pls pls pls help if ur good with angles and sides
Answer:
∆PQR: Equilateral Triangle
∆PRT: Scalene Triangle
∆TQS: Isosceles Triangle
∆QNP: Right Triangle
Step-by-step explanation:
∆PQR is an Equilateral Triangle because all of its angles are equal (60°).
∆PRT is a Scalene Triangle because none of its sides are equal.
The triangle above it is equilateral, and one side length is 14, meaning all of its side lengths are 14.
This makes the top of ∆PRT 14. The hypotenuse is given and it’s 18.
The last side left is clearly shorter than both, meaning none of the sides are equal.
∆TQS is an Isosceles Triangle because 2 angles are equal.
The base angles are both 76°.
∆QNP is a Right Triangle because segment QN and PR are perpendicular, creating two 90° angles on both sides.
For number 10, I suggest using a graphing calculator or desmos to graph the points. (Or you can just add the points but I suggest graphing).
From there, you can count the length of each side.
Segment DE: 9
Segment EF: 8
Segment FD: 10
This makes ∆DEF in number 10 a Scalene Triangle because none of its sides are equal.
For number 11, I also suggest graphing the points and counting the sides.
Segment DE: 7
Segment EF: 9
Segment FD: 7
This makes ∆DEF in number 11 an Isosceles Triangle because 2 of its sides are equal.
Hope this helps! :)

Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn) have a completely filled outer electron shell and are therefore called inert gases. What do the inert gases have in common?
1.They behave similarly in chemical reactions
2.They have the same number of protons
3.They have the same number of electrons
4.They belong to the same period
Answer:
The answer would be 1.
Answer:
They behave similarly in chemical reactions
Step-by-step explanation:
Because their atomic numbers are different, the elements each have a different number of protons and electrons. They belong to the same group, not the same period.
Miguel gave 5 items to the clerk at the store. Before taxes were added the total was 36.00. If each item was priced the same, what is the cost of one of the items?
Answer:
$7.20
Step-by-step explanation:
$36.00 for 5 items.
Divide $36.00 by 5 to find the price of 1 item.
$36/5 = $7.20

pls do this i’ll give brainliest!!
Answer:
7. move to the right by 4 units and down by 5 units
8. just rotate it to the left side (180 degrees is a flat line in the opposite direction)
9. reflection is pretty easy, just pretend you are folding your paper in half. so just redraw it on the other side in the opposite direction (fold paper sideways)

y = 1/3x +b
1 = 1/3(9) +b
1 = 3 +b
subtract 3 from both sides
-2 = b
y = 1/3x - 2Can someone explain both of these ratios and answers to me?
Answer:
15 ( for Herimone) And 8 ( For Stranger Things)
Step-by-step explanation:
When Herimone uses 5 grams of Pearl Sheen she creates 30 fluid ounces of love potion. Last week she created 90 ounces which is 3 times larger than 30 ounces so you have to multiply 5 by 3 to figure out the amount of Pearl Sheen she used which is 15
For stranger things they Multiplied 3 by 2 so you have to multiply 1 by 2 to get 2. Then you have to add 6 and 2 to get 8 kids.
Hope This Helps!
When 0.3(4x – 8) – 0.5(–2.4x + 4) is simplified, what is the resulting expression?
Answer:
2.4x - 4.4
Step-by-step explanation:
0.3(4x – 8) – 0.5(–2.4x + 4)
1.2x - 2.4 + 1.2x -2
2.4x - 4.4

In the triangles shown below, AABC is similar to AXYZ. Given that ZA = 50° and
ZB = 100°, what is the measurement of ZZ? * plz help
Answer:
B. 30°
Step-by-step explanation:
Given in the question that triangle ABC and similar to triangle XYZ where ∠A = 50° ,∠B=100° then its true to say by AA { Angle-Angle} similarity ;
if ΔABC ≅ ΔXYZ then
∠A =∠X
∠B = ∠ Y
hence ; ∠C = ∠Z
Finding angle ∠C as ;
180°-{100+50}°
180°-150° = 30°
So angle ∠Z = 30°

Isoceles and Equalateral Triangles. Need help fast
Answer:
d
Step-by-step explanation:
the angle measures in all equilateral triangles are the same
so divide 180 by 3 and you get 60
Answer: 60
Step-by-step explanation: An acute triangle must have angles that added up equal 180 degrees. The angles are the same value, and 60 times the three angles gives us 180.

Step-by-step explanation:
The size of the left upper chamber of the heart is one measure of cardiovascular health. When the upper left chamber is enlarged, the risk of heart problems is increased. The paper "Left Atrial Size Increases with Body Mass Index in Children" (International Journal of Cardiology [2009]:1-7) described a study in which the left atrial size was measured for a large number of children age 5 to 15 years. Based on this data, the authors concluded that for healthy children, left atrial diameter was approximately normally distributed with a mean of 26.4 mm and a standard deviation of 4.2 mm.Approximately what proportion of healthy children has left atrial diameters less than 24 mm?Approximately what proportion of healthy children has left atrial diameters greater than 32 mm?Approximately what proportion of healthy children has left atrial diameters between 25 and 30 mm?For healthy children, what is the value for which only about 20% have a larger left atrial diameter?
Answer:
so you need the value for the 20% right ?
