Answer:
what graph
Step-by-step explanation:
If f(1) = 9 and f(n) = 4f(n − 1) then find the value of f(4).
Answer:
576
Step-by-step explanation:
f(2) = 4f(1) = 4*9 = 36
f(3) = 4f(2) = 4 * 36 = 144
f(3) = 4f(3) = 4 * 144 = 576

A jacket is reduced by 12% to £66 in a sale.
Find the original price.
Answer:
£75
Step-by-step explanation:
100-12=88
88÷88=1%
66÷88=0.75
1%=0.75
times by 100
100%=£75
In the figure below, find the exact value of z.
9514 1404 393
Answer:
z = 9/2
Step-by-step explanation:
The triangles in the figure are all similar, so the side lengths are proportional.
long side/hypotenuse = z/6 = 6/8
z = 36/8 = 9/2 . . . . multiply by 6

-7m²-10m+17
common factor
Answer:
Greatest common factor of 17
So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!
Step-by-step explanation:
Add and subtract the second term to the expression and factor by grouping.
- (m - 1 )( 7m + 17 )
if you could anwser the second question that would be great caus e i only get to do this proble once :) no explanation needed
Angle 1 and 2 are equal because of correspondence angle
so , (78-2x) = (89-3x)
x = 89 - 78
x = 11
hence angle 1 = ( 78 - 2*11) = 56
and angle 2 = ( 89-3*11) = 56
So, both of angle is 56

I have to turn it in by tonight
Answer: (x,y) -> (x,-y)
Step-by-step explanation:
If you take any point, for example (-1,1) from the blue shape, you have to multiply the y value by -1 to get to (-1,-1) for the red shape. You can test it out with any point on the two figures.
Also, by looking at it, you can see that it is a reflection over the x axis and a reflection over the x axis always just multiplies the y value by -1.
Explain how to solve the equation 21 = m +14. What is the value of m?

AB=
BC =
AC=
PQ=
QR=
PR=
Answer:
AB = 51
BC = 50
AC = 42
PQ = 42
QR = 42
PR = 59
Step-by-step explanation:
Perimeter of ∆ ABC = Perimeter of ∆ PQR
3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3
9x + 17 = 10x + 3
17 - 3 = 10x - 9x
14 = x
.: x = 14
AB = 3x +9 = 3×14+9 = 42+9 = 51
BC = 3x +8 = 3×14+8 = 42+8 = 50
AC = 3x = 3×14 = 42
PQ = 3x = 3×14 = 42
QR = 3x = 3×14 = 42
PR = 4x +3 = 4×14+3 = 56+3 = 59

Solve the system of linear equations.
Answer:
x=1 and y= 5[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
To solve this, lets take the first equation and find the x value.
Because it is ordered in standard form, we need to convert to slope-intercept form, and isolate the y.
5x+4y=16
-5x -5x
4y=-5x+16
÷4 ÷4 ÷4
y=[tex]\frac{-5}{4}[/tex]+4
or
y=-1[tex]\frac{1}{4}[/tex]+4
or
y= 5[tex]\frac{1}{4}[/tex]
Now that we have the y value, we can use this to find the x value by inserting it into either equation, since they both have y values in them. Going with the first one again, lets try it:
5x+4([tex]\frac{-5}{4}[/tex]+4)=16
5x-5+16=16
5x+11=16
-11 -11
5x=5
÷5 ÷5
x=1 and y= 5[tex]\frac{1}{4}[/tex]

The area of a rectangular poster board can be represented by the expression
64x²y. If the width is 16xy, which expression represents the length of the poster
board?
A = length * width
Answer:
Step-by-step explanation:
A = length * width
Length = A ÷ width
[tex]= \frac{64x^{2}y}{16xy}\\\\= 4*x^{2-1}*y^{1-1}\\\\= 4x^{1}*y^{0}\\\\= 4x*1\\=4x[/tex]

7. What is the slope of the line that passes through the points (14, -18) and (5, -12)?
Answer:
slope =[tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope, or [tex]m[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:
[tex]m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}[/tex]
Thus, the slope is [tex]-\frac{2}{3}[/tex].
