A bow and arrow cost £28. The bow
costs £25 more than the arrow.
Make two equations and solve them to
find the cost of a bow and arrow.
Use b for the cost of a bow and a for
the cost of an arrow.
Equation 1 total cost
Equation 2 difference
[4]
A bow costs £
An arrow costs £
[4]
Mark it
Answer:
equation 1. 28 = b + a
equation 2. 28 - 25 = 3
bow costs 25
arrow costs 3

A line passes through the points (-4,-1) and (4,3). A second line passes through the points (-2,-2) and (2,6). At what point do the two lines intersect
Answer:
(-2/3 , 2/3)
Step-by-step explanation:
Line 1: (-4,-1) (4,3)
m = (3 - -1) / (4 - -4) = 4/8 = 1/2
equation: (y-3)/(x-4) = 1/2 y-3 = 1/2 x - 2
y = 1/2 x + 1 ....(1)
Line 2: (-2,-2) (2,6)
m = (6 - -2) / (2 - -2) = 8/4 = 2
equation: (y-6)/(x-2) = 2 y-6 = 2x - 4
y = 2x + 2 ...(2)
(2)-(1): 0 = 3/2x + 1
3/2 x = -1 x = - 2/3
y = 1/2 * (-2/3) + 1 = 2/3

What are some possible reasons for DNA mutations that could occur in a person?
Answer:
Acquired or somatic mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

•V(n)=4+(0.3)^n
•V(n)=4+(1.3)^n
•V(n)=4(0.3)^n
•V(n)=4(1.3)^n
Answer:
Step-by-step explanation:
[tex]V(n)=4(1.3)^n[/tex]
Answer:
V(n)=4(1.3)^n
Step-by-step explanation:
4 is the original value
1.3x is how much the value multiplies every year
n is the amount of years
It's not the 1st or 3rd since that would be depreciating value
It's not the 2nd because that's adding a value instead of multiplying the original
Describe the graph of the equation y = 0. Is the equation a function?
vertical line; yes
horizontal line; yes
vertical line; no
horizontal line; no
Answer: B. horizontal line; yes
Use the slope-intercept form to find the slope and y-intercept.
Slope:
0
y-intercept:
(0,0)
Yes it is a function. It is a horizontal line.
Every point on this line is of the form (x,4) where x can be any number you want. The y coordinate is fixed at 4 and cannot change. Two points on this line are (0,4) and (1,4). The horizontal line goes through 4 on the vertical y axis.
Why is it a function? Because it is impossible to draw a vertical line through more than one point on the graph of y = 4. The graph passes the vertical line test. Put another way, for any x input, there is exactly one y output.
Side Note: y = 4 is the same as y = 0x+4. Note how its in the form y = mx+b
m = 0 is the slope
b = 4 is the y intercept
Step-by-step explanation: A. vertical line; yes
horizontal line; yes
Yes! Horizontal line represents a function y = f(x)
(1):Firstly, lets understand a function. For a function to be defined, we have a set of independent variables(inputs) (Domain), a set of dependent variables (outputs) (Codomain). And a relation between the variables.
(2): Each input in X must be related to exactly one output in Y. Or else it won't represent a function.. like in the following image.. y is a function of x.Because each element ofX has one& only one image in Y
C. vertical line; no

Solve: 5x=-6x+9
A: x= -9
B: x= -9/11
C: x= 9
D: x= 9/11
Answer:
x = 9/11
Step-by-step explanation:
5x = -6x + 9
Add 6x to both sides
11x = 9
Divide both sides by 11
x = 9/11
Answer:
X Equals 9/11
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable. So X will equal 9/11, which in decimal form is 0.81.

therefore
18=10+2x
solve for x
8=2x
x=4
Answer:
The value of x is 4
Step-by-step explanation:
For a given rectangle
Lenght (l) = 2y = 10
Breadth (b) = 10 + 2x = 18
Here,
2y = 10 ...(1)
10 + 2x = 18 ...(2)
Now, For x
10 + 2x = 18
2x = 18 - 10
2x = 8
x = 8/2
x = 4
Thus, The value of x is 4
