Answer:
16. [tex]y=7x[/tex]
17. [tex]y=0.5x[/tex]
18. [tex]y=3x[/tex]
19. [tex]y=2x[/tex]
Step-by-step explanation:
Equation is [tex]y=kx[/tex] where k is a constant of proportionality.
16.
[tex]\frac{y}{x}=\frac{10.5}{1.5}=\frac{14}{2}=\frac{24.5}{3.5}=\frac{35}{5}=7[/tex]
So, equation is [tex]y=7x[/tex]
17.
[tex]\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5[/tex]
Equation is [tex]y=0.5x[/tex]
18.
[tex]\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3[/tex]
Equation is [tex]y=3x[/tex]
19.
[tex]\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2[/tex]
Equation is [tex]y=2x[/tex]

Answer:
x = 60
Step-by-step explanation:
The two angles shown here are known as corresponding angles. This means they both equal the same amount of degrees. Knowing this, we can set up an equation:
2x + 15 = 135
2x = 120
x = 60
Therefore, x = 60
You can check your answer by substituting the answer for x:
2(60) + 15 = 135
120 + 15 = 135
135 = 135

H = -16t^2 + 84t + 100 what is maxium height
Answers
Answer:
[tex]H=210.25\ \text{units}[/tex]
Step-by-step explanation:
Given that,
[tex]H = -16t^2 + 84t + 100[/tex] ...(1)
We need to find the maximum height
For maximum height, put dH/dt = 0
[tex]\dfrac{d(-16t^2 + 84t + 100)}{dt}=0\\\\-32t+84=0\\\\t=\dfrac{84}{32}\\\\t=2.625\ s[/tex]
Put t = 2.625 in equation (1)
[tex]H = -16(2.625)^2 + 84(2.625) + 100\\\\=210.25\ \text{units}[/tex]
Hence, the maximum height [tex]=210.25\ \text{units}[/tex]
The regular octagon shown is divided into 8 congruent triangles. Each triangle has an area of 21.7 square centimeters. The
Perimeter of the octagon is 48 centimeters.
Answers
The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm.
What is a triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.
In a triangle, the sum of all three angles is 180°
Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.
Given the octagon with a perimeter of 48 cm
Let's say the length of each side is a
Perimeter = 8a
8a = 48
a = 6cm
Now,
The area of the triangle is given by
A = 1/2 × Base × Height
A = 1/2 × 6 × h
A = 3h
Now
A = 3h and the area is 21.7 cm²
So,
h = 21.7/3 = 7.23 cm
Hence "The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm".

Step-by-step explanation:
Hope this helps. Pls give brainliest.
Answer:
x = 0
y = 3.25
Step-by-step explanation:
You can do elimination. Multiply (9x + 4y = 13) by 2
4x - 8y = -26
18x + 8y = 26
22x = 0
x = 0
4(0) - 8y = -26
-8y = -26
y = 3.25
