What is 65% of 20?
ye
Answer:
13
Step-by-step explanation:
x/20 = 65%/100
20 x 65 = 1300
1300 divided by 100 = 13
Answer:13
First you have to turn the percent into a decimal, and then multiply it by the original number.

Answer:
Dark blue on the left.
Step-by-step explanation:
The simplest way is to plug in the values. However, you can immediately get rid of yellow and red because the y intercept is -2.
We have two equations left so the best is plug in the points (0,-2).
For the first equation, 4x^2-2, plug in x which is 0.
4(0)^2-2. Simplify to get 0-2. y=-2.
Dark blue is the answer.

Answer:
a = 8, b = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given the exponential function
f(x) = a[tex]b^{x}[/tex]
To find a and b use the given coordinate points on the graph
Using (0, 8 ), then
8 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then
a = 8
f(x) = 8[tex]b^{x}[/tex]
Using (2, 18 ) , then
18 = 8b² ( divide both sides by 8 )
[tex]\frac{18}{8}[/tex] = b² , that is
b² = [tex]\frac{9}{4}[/tex] ( take the square root of both sides )
b = [tex]\sqrt{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex]
Thus
f(x) = 8[tex](\frac{3}{2}) ^{x}[/tex]
5x+20=55 what does x equal?
Answer:
5x+20=55
5x=55-20
x=30/5=7
Answer:
x = 7
Step-by-step explanation:
5x + 20 = 55
- 20 - 20
5x (÷5) = 35 (÷5)
x = 7
What equation is being graphed?
A. y+5= -3/2(x-4)
B. y-5= -2/3(x+4)
C. y-5= -3/2(x+4)
D. y-4= -3/2(x+5)
Answer:
D. y-4= -3/2(x+5)
Step-by-step explanation:
Firstly, taking two valid ordered pairs from the graph:
(-2,4) and (2,-2)
Using Delta y over Delta x, we are able to obtain m as -3/2
Next,
The following is the point-slope formula:
y-y₁=m(x-x₁)
Based on the graph, (4,-5) can be spotted as a definite ordered pair
Therefore, y-4= -3/2(x+5) fits the graph best and has the appropriate m value.

the sum of the measures of two exterior angles of a triangle is 272. what is the measure of the third exterior angles
Answer.
Step-by-step explanation:
Given = sum of two exterior angle of a triangle is 272 .
rule of triangle is that each and every angle which are outside a triangle is 360.
so, 272 + x = 360
x = 360 - 272
x = 88
this is RAY MAK who knows him
A triangle is dilated with a center of dilation at the origin. Point P is on the figure and P' is the corresponding point on the image of the dilation. Point P is at (-2, 3) and P' is at (-8, 12). Which rule best represents the dilation? *
Answer:
(x, y) → (4x, 4y)Step-by-step explanation:
Dilation is applied by the rule:
(x, y) → (kx, ky), where k is the scale factorWe have
(x, y) = (-2, 3) and (kx, ky) = (-8, 12)Substitute and solve for k
-8 = -2k and 12 = 3k ⇒ k = 4So the rule is
(x, y) → (4x, 4y)Please help this is dew in 20 minutes

system of equations
Answer:1:(2,7)
2:i or (1,-3)
3:is c or (-15,-25)
Step-by-step explanation:like if this helped mark me brainlest please
Answer:
(2,7)
(1,-3)
(-15,-25)
Step-by-step explanation:
Because both equations are equal to the same thing (y) we can just set them equal to each other and solve for x
4x-1=2x+3
solve for x
4x=2x+4
2x=4
x=2
We know that x=2 and can plug this value in for x into any of the beginning equations
4(2)-1=y
7=y
The answer is (2,7)
2.) We can do the exact same process as question one
x-4= -3x
-4= -4x
x=1
plug this x value in into any of the starting equations
1-4=y
-3=y
The answer is (1,-3)
3.) Same deal as the other two
x-10=2x+5
-x=15
x= -15
Plug this value in for x into any beginning equation
2(-15)+5
-30+5
y= -25
(-15,-25)
