If f(x)=3x-4 and g(x)=x2 find the value of f(3)-g(2).
Is this relation a function?Explain
Answer:
Yes it's a function
Step-by-step explanation:
Its a function because the rule of a function is the values of one variable quantity to the variables of another quantity. And that is what the picture shows
The ratio of boys to girls in a camp is 6 to 8. How many girls are there in the camp if there are 96 boys in the camp?
Answer:
128 girls
Step-by-step explanation:
The ratio of boys to girls is 6 to 8. We need to find how many girls there are if there are 96 boys in the camp. One way to solve this is by using cross multiplication:
[tex]\frac{6}{8}[/tex] = [tex]\frac{96}{x}[/tex]
multiply the 6 by the x: 6x
multiply 8 by 96: 768
6x = 768
divide both sides of the equation by 6 to isolate the x:
6x/6 = 768/6
x = 128
When there are 96 boys in camp, there will be 128 girls.
Answer:
6/8=96/x

Answer:
[tex]x = 71[/tex]
Step-by-step explanation:
The first step to do is make a single triangle from the problem. That triangle can be BDH. We do still need the line BE, although that can wait.
Now find the last angle of the triangle. The sum of angles of a triangle always equal 180, so we can easuly find the missing angle.
[tex]180 - 40 - 31 = 109[/tex]
So the missing angle is 109°. Now we can find the value of x.
We can use that angle because it sits right next to x on the same line. A line is 180° at any node as long as the line continues straight, so we simply subtract the angle we just found to find x.
[tex]180 - 109 = 71[/tex]
Now we know x is 71

1: x
x = 15
1 ounce of Instant coffee equals 15 cups
25-15 = 10
10 is 2/3 of 15 so
1 = 15
+.66 = 10
1.66 = 25

measure angle 1 is corresponding to measure angle 5
measure angle 5= measure angle 1= 71*
measure angle 5 + measure angle 8 = 180*
71*+ measure angle 8=180*
measure angle 8=109
Answer:
[tex]m\angle5 = 71\degree^{\circ}[/tex],
[tex]m\angle8=109^{\circ}[/tex]
Step-by-step explanation:
Given that [tex]a[/tex] and [tex]b[/tex] are parallel and [tex]m\angle1=71^{\circ}[/tex]:
[tex]m\angle5 = 71^{\circ}[/tex] (Corresponding angles are equal when [tex]a\parallel b[/tex] )
[tex]m\angle8+m\angle5=180^{\circ}[/tex] (The two angles make up the angle of a straight line: [tex]180^{\circ}[/tex]
[tex]m\angle8 + 71^{\circ} = 180^{\circ}[/tex]
[tex]m\angle8 = 109^{\circ}[/tex]
[tex]\therefore m\angle5=71^{\circ};m\angle8=109^{\circ}[/tex]

[tex]x^2-4x=0[/tex]
Please show all work. Thanks!!!
Answer:
x=0 or x=4
Step-by-step explanation:
Lets Solve!
First we need to factor the left side of the equation. Both terms include x.
[tex]x^2-4x =0[/tex]
[tex]x(x-4) =0[/tex]
If we multiplied x by (x-4) we would be back at [tex]x^2-4x =0[/tex].
Set factors equal to 0.
x=0 or x−4=0
x=0 or x=4
Woohoo! Brainliest Appretiated! Hope I helped!
Answer:
[tex]x=0,4[/tex]
Step-by-step explanation:
Factor out the common terms from x²-4x. You can factor out x:
[tex]x(x-4)=0[/tex]
Multiplication can be seen as (_)(_). Rewrite:
[tex](x)(x-4)=0[/tex]
Set both equal to 0:
[tex]x=0\\\\x-4=0[/tex]
Simplify the second equation:
[tex]x-4=0\\\\x-4+4=0+4\\\\x=4[/tex]
So, x=0 or x=4
