Answer:
2x + 5y = 6
Step-by-step explanation:
The equation of a line parallel to 2x + 5y = 30 has exactly the same form as does 2x + 5y = 30, but the constant is different. Starting with 2x + 5y = 30, replace the constant (30) with C, x with 3 and y with 0:
2(3) + 0 = C, so C = 6
Then the desired equation is 2x + 5y = 6

For the triangle it is given that AE2 + EB2 = 9 and BE2 + EC2 = 16
Find AC =
Answer:
Step-by-step explanation:Given : right triangle ABC , AE^2 + EB^2 =9 and BE^2 + EC^2 = 16
To find : AC
Solution:
BE ⊥ AC
∠AEB = 90°
=> ΔAEB is right angled
=> AB² = AE² + EB²
=> AB² = 9
∠BEC = 90°
=> ΔBEC is right angled
=> BC² = BE² + EC²
=> BC² = 16
∠ABC = 90°
=> AC² = AB² + BC²
=> AC² = 9 + 16
=> AC² = 25
=> AC = 5
AC = 5
The length of AC is 5 units.
What is a Triangle?Any three-sided polygon having three edges and three vertices is referred to as a triangle in geometry. The most important attribute of a triangle is that its internal angles sum to 180 degrees. The triangle's angle sum attribute is what is known as.
As per the given data:
We are given the diagram of ΔABC which is right-angled.
BE is perpendicular to AC.
AE² + EB² = 9 ...(i)
BE² + EC² = 16 ..(ii)
By using the Pythagoras theorem in ΔABE:
AE² + EB² = AB²
From comparing with eq (i)
AB² = 9
AB = √9 = 3 units
By using the Pythagoras theorem in ΔCBE:
BE² + EC² = BC²
From comparing with eq (ii)
BC² = 16
BC = √16 = 4 units
By using the Pythagoras theorem in ΔABC:
AB² + BC² = AC²
AC² = 3² + 4²
AC² = 9 + 16 = 25
AC = 5 units.
The length of AC is 5 units.
Hence, The length of AC is 5 units.

Since the triangle is a special 30°-60°-90° triangle, the hypotenuse is twice the size of the shortest leg. The long leg is [tex]\sqrt{3}[/tex] of the short leg.
Find the value of x.
Answer: x = 20
Step-by-step explanation:
The angle is 90 degrees so we can make an equation
with it.
3x + 10 + x = 90
Combine like terms
4x + 10 = 90
subtract 10 from both sides to cancel it out
4x = 80
Now divide by 4 to leave x by itself
x = 20
Now you can check if it's correct by plugging in x to the equation given
3(20) + 10
60 + 10
70
20 + 70 = 90 degrees
Answer:
D: 20 degrees
Step-by-step explanation:
First, we add 3x+10 and x together because they are within a right angle, which is 90 degrees. This gives the equation 4x+10=90. We solve from here.
We subtract 10 from both sides to isolate the x-variable. 90 minus 10 equals 80. This gives us the equation 4x=80. To further isolate the x-variable, we divide both sides by 4. 80 divided by 4 equals 20.
This leaves us with x=20.

What is an equation of the line that passes through the points (-6, -2) and
(6,8)?
Answer:
y=5/6x+b
Step-by-step explanation:
use formula (y2-y1)/(x2-x1) to look for the slope:
(8-(-2))/(6-(-6))
=10/12
=5/6 (simplified)
then, use the formula y=mx+b to get the equation by substituting m and x, y to either (-6, -2) or (6, 8):
8=5/6(6)+b
8=5+b
3=b (subtract 5 on both sides)
equation:
y=5/6x+3

How many 3-inch thick bags of mulch should Noemi buy to cover 100 square feet at a depth of 4 inches? The length is 3.2ft and the width is 2.5ft.
Answer:
Approximately 17 bags.
Step-by-step explanation:
The length of the bag of mulch = 3.2 ft
The width of the bag of mulch = 2.5 ft
The thickness of the bag of mulch = 3 inch = 0.25 ft
Volume of a bag of mulch = length x width x thickness
= 3.2 x 2.5 x 0.25
= 2 cubic feet
So that, the volume of a bag of mulch is 2 cubic feet.
The area to be covered = 100 square feet
The depth of the area = 4 inches = [tex]\frac{1}{3}[/tex] feet
volume of the portion to be covered = area x depth
= 100 x [tex]\frac{1}{3}[/tex]
= 33 [tex]\frac{1}{3}[/tex] cubic feet
The volume of the portion to be covered is 33 [tex]\frac{1}{3}[/tex] cubic feet.
The number of bags of mulch needed = [tex]\frac{33\frac{1}{3} }{2}[/tex]
= 16[tex]\frac{2}{3}[/tex]
= 16.6667
The number of bags of mulch needed is 17.

Write 34% as a fraction or mixed number in simplest form.
The simplest form is
Basic
Answer:
17/50.
Step-by-step explanation:
In order to write 34% as a fraction or mixed number in simplest form, the following calculation has to be done:
34% = 0.34 = 34/100
34/100 = 17/50
Thus, given that 17 is a prime number that cannot be divided by other number than 1 or 17, the simplest form to write 34% as a fraction is 17/50.

1. There are 34 rose bushes currently in the park. Park workers will plant
more rose bushes today.
When the workers are finished there will be 70
rose bushes in the park. How many rose bushes did the workers plant
today?
34 + 70 = x; x = 104
34 - x = 70 ; x = 36
34 + x = 70; x = 36
70 - 34 = x; x= 36
Answer:
34 + x = 70 ; 36
Step-by-step explanation:
Given that:
Current amount = 34
Final amount = 70
Number of roses planted by the workers today ;
Current amount + number planted today = final amount
Let number planted today = x
34 + x = 70
x = 70 - 34
x = 36

Standard form: a(X-h)²+k = ( -2/3X² -16/3X -32/3) +32/3 -17/3 = -2/3(X +4)² +5
y = -2/3*X^2-16/3*X-17/3
X = -4 ±√( 15/2) = -6.7386, or -1.2614
Axis of symmetry: X= -4; Vertex (maximum)=(h,k)=( -4, 5); y-intercept is (0,-5.66666666667)
two real roots: X=-1.2613872124776866 and -6.738612787477313
Answer:
b) y = -2/3(x + 4)² + 5c) y = 1/2(x + 8)² - 5d) y = 3/8(x + 7)² - 2Step-by-step explanation:
Vertex form is:
y = a(x - h)² + kVertex of the function is point (h, k)
b) Congruent to y = 2/3x² and opens down means:
a = -2/3Maximum value at (-4, 5) means:
h = -4, k = 5The function is:
y = -2/3(x + 4)² + 5c) Congruent to y = 1/2x² and has minimum value y = -5 at x = -8:
a = 1/2, h = -8, k = -5The function is:
y = 1/2(x + 8)² - 5d) Vertex (-7, -2) and passes through the point (-3, 4)
y = a(x + 7)² - 2Substitute coordinates and find a:
4 = a(-3 + 7)² -26 = 16aa = 3/8The function is:
y = 3/8(x + 7)² - 2
