Answer:
The system of equations has no solution.
Step-by-step explanation:
Given the system of equations
2y = 2x+7
x = y+2
solving the system of equations
[tex]\begin{bmatrix}2y=2x+7\\ x=y+2\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}2y-2x=7\\ -y+x=2\end{bmatrix}[/tex]
Multiply -y+x=2 by 2: -2y+2x=4
[tex]\begin{bmatrix}2y-2x=7\\ -2y+2x=4\end{bmatrix}[/tex]
so adding
[tex]-2y+2x=4[/tex]
[tex]+[/tex]
[tex]\underline{2y-2x=7}[/tex]
[tex]0=11[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}2y-2x=7\\ 0=11\end{bmatrix}[/tex]
0 = 11 is false, therefore the system of equations has no solution.
Thus,
No Solution!

Saffron is very expensive spice. A shop selling saffron for $ 7.35 per gram.
Write the formula for the cost (y), in dollars, of g grams of saffron.*
a) y = 7.35g
b)g=7.35 y
c) y = 7.35+g
Answer:
A
Step-by-step explanation:
B is wrong because it's saying to multiply the cost by $7.35.
C is wrong because it's telling you to add the amount of grams to $7.35.
A is the correct answer because you have to mutiply the cost by the grams which is what a number by a variable means.
Saffron is one the most expensive spices in the world. Ms. Patel pays $123.51 for 2.3 grams of saffron. What is the price per gram?

The radius of a circular field is 35m. Calculate the area path 3.5m wide running inside the field.
Answer: Twenty one meeters!!
Answer: The area of the path running around the inside edge of the field is 731.2 m²
If the path is across the middle of the field, the area of that path is about 245m²
Step-by-step explanation:
The radius of the field is 35m, subtracting 3.5 from that leaves the radius of the inside edge of the path at 31.5 m
The area of the path will be the difference between the two areas.
π × 35² = 3848.45
π × 31.5² = 3117.25
3848.45 - 3117.45 = 731.2
If the path is across the middle of the field, use the diameter, 70m, times the width of the path, 3.5m, to find the area of that path: 245m²
I hope this helps.

Work Done (J) = Force (N) x Distance (m)
Calculate the distance that an object is moved with the
following force applied and work done:
50 N and 300 J
Answer:
distance = 6.0 m
Step-by-step explanation:
1. Take note of the given.
Force = 50 N Work Done = 300 J m = ?
2. Write the formula.
J = Nm
3. Substitute.
300 J = (50N)(m)
4. Divide both sides by 50 N to isolate m.
300 J / 50 N = m
6 = m

Solve For X
(see picture below)
thank you!
Answer:
x = 6
Step-by-step explanation:
If two secants are drawn from a point outside the circle, then the product of the lengths of one secant and its external segment equals the product of the lengths of the other secant and its external segment
Let us solve the question.
∵ There is a circle in the given figure
∵ There are two secants intersected at a point outside the circle
∵ The length of one of them = 8
∵ The length of its external segment = x
∵ The length of the other secant = 4 + 8 = 12
∵ The length of its external segment = 4
→ By using the rule above
∴ 8 × x = 12 × 4
∴ 8x = 48
→ Divide both sides by 8
∴ x = 6

How do we make graph of a function?Suppose the considered function whose graph is to be made is
f(x)
The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values
f(x)
are plotted on the vertical axis.
They are together plotted on the point
(x,y) = (x, f(x))
This is why we usually write the functions as:
y = f(x)
Given;
y= - 1/4x -7
Now, the graph of the function is given in the image.

Answer:
15 seconds
Step-by-step explanation:
Put the given heights in the equation and solve for t.
h(t) = -16t² +3600
0 = -16t² +3600 . . . . h(t) = 0 at ground level
16t² = 3600 . . . . . . . add 16t²
t² = 3600/16 = (60/4)² = 15² . . . . . divide by 16
t = 15 . . . . . . . . . . . . take the square root
It will take 15 seconds for the phone to hit the ground.
