Here is a linear equation: y = 1/4x +5/4
Are (1, 1.5) and (12, 4) solutions to the equation?
Yes or No?
PLEASE NEED HELP
Answers
Step-by-step explanation:
(1,1.5) is the solution but (12,4) is not the solution of given equation.
1.5=1/4×1+5/4(which is true)
4=1/4×12+5/4(which is false)
The point )1,1.5) is satisfying the equation y=(1/4)x + (5/4) and the point (12,4) is not satisfying.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Given points are (1, 1.5) and (12, 4). To check whether the points are the solution of the equation or not substitute the coordinates in the equation and check if LHS is equal to RHS then it is a solution otherwise not.
Check the point (1,1.5),
y=(1/4)x + (5/4)
4y = x + 5
(1.5)4 = 1 + 5
6 = 6
Check the point (12k,4),
y=(1/4)x + (5/4)
4y = x + 5
(4 x 4 ) = 12 + 5
16 ≠ 17
Therefore, the point )1,1.5) is satisfying the equation y=(1/4)x + (5/4) and the point (12,4) is not satisfying.

Using their equation and the fact that the ball will fall 3 ft before reaching the ground:
3 = 16 t^2 + 50 t + 3 represents the given situation
16 t^2 + 50 t = t (16 t + 50) = 0
16 t + 50 = 0

Pqr=qps work out the value of qps
Answers
Answer:
89°
Step-by-step explanation:
Total inner degree of PQRS = (4-2)*180° = 360°
PST is a straight line : 180°
angle PSR = 180-128
=52°
angle RQP + angle QPS = 360 - 52 - 130 = 178°
Angle PQR = Angle QPS
Angle QPS = 178/2 = 89°

The value of the base length x of the right angle triangle to the nearest tenth is 18.4.
What is the value of x?From the diagram;
Angle θ = 49°Hypotenuse = 28Base length x = ?We use trigonometric ratio since its right angle triangle.
Cos = Adjacent / Hypotenuse
Cosθ = Base length / Hypotenuse
Cos( 49° ) = x / 28
x = Cos( 49° ) × 28
x = 0.656059 × 28
x = 18.4
Therefore, the value of the base length x of the right angle triangle to the nearest tenth is 18.4.

Tell me what this answer is plz I need a good grade if u can help thx
Answers
Answer:
46 degrees
Step-by-step explanation:
You should know that measures QRS, which form a horizontal line, measures up to 180 degrees. (Just like a right angle adds to 90 degrees). So, TRS is 42 degrees and URT is 92 degrees, that would make QRU measure 46 degrees because 180 - 92 - 42 = 46 degrees.
Hope that helps you!! Please give me brainliest!! ;)
Answer:
42°
Step-by-step explanation:
A horizontal, or flat line is 180°. This means the total measures of ∠TRS, ∠URT, and ∠QRU, are 180°. We can subtract the given measures from 180 to find the measure of ∠QRU.
∠TRS = 42°
∠URT = 92°
Subtract 42 and 92 from 180.
180 - 42 - 92 = 46
∠QRU = 42°
m∠QRU in circle R is 42°.

Help please. It’s geometry and it asks to find the shaded region.
Answers
Answer: (a)
Step-by-step explanation:
Given
The diameter of the inner circle is [tex]d=14\ m[/tex]
thickness of the strip is [tex]t=2\ m[/tex]
So, the radius of inner circle is [tex]r=7\ m[/tex]
Radius of the outer circle [tex]R=7+2=9\ m[/tex]
Area of the shaded region is the difference of the area of outer circle and inner circle.
[tex]\Rightarrow \pi R^2-\pi r^2\\\Rightarrow \pi (9^2-7^2)\\\Rightarrow 3.142\times 32\\\Rightarrow 100.5\ m^2[/tex]
