Find p(4) and p(-2) for each function.
p(x) = x² – 3x + 8
Answer:
p(x)=x2 - 3x + 8
p(4) =(4)2 - 3(4) + 8
= 16 - 12 + 8
= 4+8
= 12
p(-2)= (-2)2 - 3(-2) + 8
= 4+6+8

BC = 12 and AB = 11. Find AC.
Answer:
AC = 23
Step-by-step explanation:
Assuming A, B, and C are on a line with B in the middle...
We know that AB + BC = AC. Travelling from A to C is the same as travelling from A to B, then B to C, as B is on the way between A and C.
Knowing this, we can set up this equation and add the 2 numbers we know:
AC = AB + BC
AC = 11 + 12
AC = 23
suppose Q is the midpoint of PR. use the information to find the missing value. PQ equals 3x + 14 and QR equals 7X - 10; find X.
Answer:
x=6
Step-by-step explanation:
A midpoint is the middle point of a line segment, therefore it is equal distances from both ends of the segment.
This means that PQ and QR have the same length. So all we have to do is set each value equal to each other, and then solve for X.
[tex]3x+14=7x-10\\3x+24=7x\\24-4x\\x=6[/tex]
Answer:
x=-0.4
Step-by-step explanation:
ok you have to visualize this line
P Q R
O---------------------O-----------------------O
3x+14 7x-10
so to make the equation of PR you would add PQ and QR together.
3x+14+7x-10
add your like terms
10x+4
solve for x
10x+4=0
subtract 4 from each side
10x=-4
divide both sides by 10
x=-2/5 fraction
x=-0.4 decimal
What is the rate of change for the points (0,3) and (2,7)
Answer:
2
Step-by-step explanation:
The rate of change in function f(x) from x = a to x = b is (f(b) - f(a))/(b - a).
rate of change = (7 - 3)/(2 - 0) = 4/2 = 2
Answer:
rate of change = 2 unit rise per 1 unit run
Step-by-step explanation:
The rate of change of two points on a graph is represented by the slope of a line connecting the two points.
here we are given the coordinates of the two points, hence we can simply apply the slope formula for a line given two points (see attached)
for points (0,3) and (2,7)
x₁ = 0, y₁ = 3, x₂ = 2, y₂ = 7
substituting these into the formula
rate of change
= slope, m
= (y₂-y₁) / (x₂-x₁)
= (7 - 3) / (2 - 0)
= 4 / 2
= 2
I know it’s a lot but I need help didn’t get the material because I’m doing online classes and my WiFi is trash
Answer: not sure if that is a b but i beleive it is so
bh+hr=25
move all terms to the left side and set equal to 0. then set each factor equal to zero.
h= [tex]\frac{25}{b+r}[/tex]
isolate the variable by dividing each side by factors that dont
contain the variable.
r=[tex]\frac{25}{h}-b[/tex]
x=[tex]\frac{r-h}{y}[/tex]
isolate the variable by dividing each side by factors that dont
contain the variable.
h=-xy+r
solve for r by simplifieng both sides of the equation, then isolating the variable.
r=xy+h
Answer:
1A. h = 25/(b + r)
1B. r = 25/h - b
2A. h = r - xy
2B. r = xy + h
Step-by-step explanation:
1. bh + hr = 25
A. h(b + r) = 25
h = 25/(b + r)
B. h(b + r) = 25
b + r = 25/h
r = 25/h - b
2. x = (r - h)/y
A. xy = r - h
h + xy = r
h = r - xy
B. xy = r - h
r = xy + h

-6 + -4 + 3 = ? Adding integers
Step-by-step explanation:
Hey there!
Here,
[tex] = - 6 + ( - 4) + 3 [/tex]
While working with them remember some rules;
(-) + (-) = sign (-) but add them.(+) + (+) = sign (+) and add.(+) - (+) = subtract but keep sign of greator number. (-) -(-) = subtract and keep the sign of greator number.Likewise in your question,
[tex] = - 6 - 4 + 3[/tex]
[tex] = - 10 + 3[/tex]
[tex] = - 7[/tex]
Hope it helps...

The second: f(-5) = 2Step-by-step explanation:
x = -5
-5 < -4 and if x<-4 then f(x) = - 2x - 8
so:
f(-5) = - 2(-5) - 8 = 10 - 8 = 2

Step-by-step explanation:
-a² + 4ab - b²
Substitute the variables with the numbers given.
-2² + 4(2×-6) - -6²
-2² + 4(-12) - -6²
-4 + 4(-12) - 36
-4 + -48 - 36
-52 - 36 =

G(x)=\sqrt{x+3}g(x)= x+3 g, left parenthesis, x, right parenthesis, equals, square root of, x, plus, 3, end square root What is the domain of g?G?
Answer:
The domain of g(x) is -3 to infinity
Step-by-step explanation:
Given
[tex]g(x) = \sqrt{x + 3}[/tex]
Required
Determine the domain of g(x)
We start by expressing the content of the square root in the following form:
[tex]x + 3 \geq 0[/tex]
Subtract 3 from both sides
[tex]x + 3 -3 \geq 0 - 3[/tex]
[tex]x \geq 0 - 3[/tex]
[tex]x \geq - 3[/tex]
This can be expressed using interval notation as follows:
[tex]\{x: -3, infiniti\}[/tex]
Hence, the domain of g(x) is -3 to infinity

All real values of x such that x ≥ −3

-Is ZFDE a possible name for the figure below? Explain.
E
D
F
It’s number 14
Answer: Yes [tex]\angle FDE[/tex] is one possible angle name
Another name is [tex]\angle EDF[/tex]
When it comes to naming an angle this way, all we need to worry about is the vertex point. This is where the angle hinges (think of a door or a pair of scissors). In this case, the hinge or vertex point is at point D. The vertex is always the middle letter of any three-letter sequence. The order of the other two points does not matter.
This is why saying "angle FDE" is the same as "angle EDF".

How do I solve this ?
Answer:
Step-by-step explanation:
I'm just going to go out on a limb here and assume that those are a set of poorly made parenthesis. This, then, would be your equation:
[tex]x+\frac{x}{7}+\frac{1}{11}(x+\frac{x}{7})=60[/tex]
The first thing to do is distribute through the parenthesis to get:
[tex]x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60[/tex]
Next is to get rid of the denominators by multiplying by the LCM of 77:
[tex]77(x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60)[/tex] which gives you:
77x + 11x + 7x + x = 4620 and
96x = 4620 so
[tex]x=\frac{385}{8}[/tex]
Simplify the expression -(2m+3)+5m

[tex]=-2m-3+5m[/tex]
Combine like terms:
[tex]=3m-3[/tex]

Answer:
x = 35°, Angle 1 = 145°, Angle 2 = 35°
Step-by-step explanation:
In a trapezoid, the angles on the same leg are supplementary, meaning they add up to 180°. That means Angle 2 plus Angle 1 equals 180°. Therefore:
[tex](4x+5)+x=180^{\circ}\\5x+5=180^{\circ}\\5x=175^{\circ}\\x=35^{\circ}[/tex]
Therefore, x = 35°, Angle 2 = 35°, and Angle 1 =
[tex]4x-5^{\circ}\\4(35^{\circ})+5^{\circ}\\140^{\circ}+5^{\circ}=145^{\circ}[/tex]
To ensure our answers make sense, we verify they equal 180°:
[tex]145^{\circ}+35^{\circ}=180^{\circ}[/tex]
