Answer:
25
Step-by-step explanation:
z+3z+25=125
4z=100
z=25
Answer: 25
Step-by-step explanation:
Combine like terms
z + 3z + 25 = 125
4z + 25 = 125
Subtract 25 on both sides
4z = 100
z = 25

What is the equation of the line that passes through the points ( − 6 , − 1 ) and (0, 2)?
Answer:
y=1/2x+2
Step-by-step explanation:
so slope = 2-(-1)/0-(-6)
=3/6=1/2
y=mx+b
plugging in the second group of cordinates.
2=1/2(0)+b
b=2
y=1/2x+2
Answer:
y=0.5x+2
Step-by-step explanation:
y=mx+c
change in y over change in x
2+1/0+6 = 0.5
m=0.5
2=0.5×0+c
2=c

Step-by-step explanation:
If triangle ABC is similar to triangle EHG, find the measure of angle EHG.
First we need to find all the interior angles. So we know that the inside of a triangle (all the angles added up) equals 180. So we need to equal all the inside angles to 180.
2x + x + 60 = 180
Now lets start to solve. First let's subtract the 60 from both sides.
2x + x = 120
Now we need to add the x's together.
3x = 120
Now we must divide the 120 by 3 to get x by itself.
x = 40
Now just replace the x with 40 to find each of the sides. I'm guessing the triangles are reflecting each other so <EHG would be equal to 80.
ALSO to check if 40 would be correct, add all the angles together in the same triangle and they SHOULD add up to be 180! Which they do!
Step-by-step explanation:
Firstly let's calculate the unknown angles in triangle ABC
2x + x + 60° = 180° { being sum of angles of triangle }
3x = 180° - 60°
3x = 120°
x = 120° / 3
x = 40°
2x = 2 * 40° = 80°
Now since it is said that triangle ABC and triangle EHG are similar so
< EHG = < ABC = 2x = 80°
Hope it will help :)

So sorry I replied so late but I'll leave the answer here just in case.
Answer:
7. Domain: [0,30] Range: [0,7]
8. f(20) = 4.67 or 4 2/3; After 20 seconds, the squirrel is 4.67 meters away from the camera.
9. x = 1.25 and x = 21.43; The quirrel is 4 meters away from the camera at 1.25 seconds and 21.43 seconds.
10. At 2.5 and 19.29 seconds
11. 10 seconds
12. The squirrel went to the back of the camera, away from its line of view.
Step-by-step explanation:
7. The line is between 0 and 30 on the x-axis and is between 0 and 7 on the y-axis.
8. The slope of the third part of the line is not a whole number, so you need to calculate it. The rise is -7 meters and run is 15 seconds, so the slope is -7/15. Plugin -7/15 into the slope-intercept form (y = mx+b) and the equation is f(x) = -7/15 x+14. Plugin x=20 into the equation:
f(20) = -7/15(20)+14
f(20) = -9.33+14
f(20) = 4.67
9. The first slope of the graph will also need to be calculated. Rise is 7-3 (4) and the run is 5. Slope = rise/run = 4/5 = 0.8. Plugin the slope into y = mx+b with the y-intercept, and the equation is f(x) = 0.8x+3. Replace f(x) with 4 and solve the equation.
4 = 0.8x+3
1 = 0.8x
x = 1.25
There is another x value that matches with f(x) = 4 in the third part of the graph, so we'll use the slope-intercept form for the previous question for this one.
4 = -7/15 x+14
-10 = -7/15 x
x = 21.43
10. The squirel is 5 meters away from the camera twice, so we'll be using the same equations for the previous question.
5 = 0.8x+3
2 = 0.8x
x = 2.5
5 = -7/15 x+14
-9 = -7/15 x
x = 19.29
11. The squirrel is 7 meters away between 5 and 15 seconds. 15-5 = 10.
12. The squirrel most likely went somehwere where the camera can't see it, and it's probably the back of it.
What's the difference between 4 3/4 and 3 1/2
Answer:
The diffrence is that 4 3/4 is greater then 3 1/2 because if you take 4 by itself by 3 then 4 will 4 because the whole number is greater so their for the intier answer will be greater. 3 1/2 is less then 4 3/4 because the whole number is lower so their for the answer is less.

HELP PLEASE. The areas of the squares adjacent to two sides of a right angle are shown above. what is the area of the Square adjacent to the third side of the triangle?
Answer:
6.5units
Step-by-step explanation:
Find the length side of the smaller square
The area of the square is equal to
A = a^2
so
a^2 = 13
a = √13 units
step 2
Find the length side of the larger square
The area of the square is equal to
A = b^2
so
b^2 = 29.25
b = √29.25 units
step 3
Find the value of x
Applying the Pythagoras Theorem
x^2 = a^2 + b^2
x^2 = 13 + 29.25
x^2 = 42.25 units
x = √42.25
x = 6.5 units
The area of the square adjacent to the third side of the triangle is 85 square units.
Pythagoras theorem:Important information:
The area of Red square is 35 square unitsThe area of Green square is 50 square units.According to the Pythagoras theorem:
[tex]a^2=b^2+c^2[/tex]
Where, a is hypotenuse and b, c are two legs of a right-angle triangle.
Area of a square is the square of side length. So, [tex]b^2=35[/tex] and [tex]c^2=50[/tex]. Now,
[tex]a^2=35+50[/tex]
[tex]a^2=85[/tex]
Therefore, the area of the square adjacent to the third side of the triangle is 85 square units.
