Answer:
The value is 24
Step-by-step explanation:
We want to find the value of the given expression when x = 5
Simply substitute 5 into the given expression.
Thus, we have;
4(5-2)(5-3) + 7(5-2)(5-5) - 6(5-3)(5-5)
Any part of the expression with 5-5 will be zero and will cancel out
Thus, we have
4(3)(2) = 4 * 3 * 2 = 24
The required value of equation at x = 5 is 24.
Given ;
Equation is = 4(x-2)(x-3) + 7(x-2)(x-5) - 6(x-3)
We have to calculate the value of expression when x = 5
To solve the equation substitute x = 5 in the given equation
= 4(x-2)(x-3) + 7(x-2)(x-5) - 6(x-3)(x-5)
= 4(5-2)(5-3) + 7(5-2)(5-5) - 6(5-3)(5-5)
Simplify the equation
= 4(3)(2) + 7(3)(0) - 6(2)(0)
= 4.(6) + 7(0) - 6(0)
= 24 + 0 - 0
= 24
The required value of the equation at x = 5 is 24.

1. What are the equation and slope of the line shown on the grid?
Answer:
y=2/5x-2
Step-by-step explanation:
The main equation you will need for this is y=mx+b
First, you have to find the slope. the equation for that is
-2-0 = -2 (y)
0-5= -5 (x)
A good way to remember this is rise over run or y is always over x
Slope = 2/5 (The negatives cancel out)
The great thing about this is that they have already given you your "y" intercept or "b" which is -2
A - Z = X
Solution the equation to find the required variable.
Answer:
A - Z = X
A - Z + Z = X + Z
A = X + Z

Statment: Find the measure of the angle indicated by 19x+5
Options: 130
50
80
100
Answer:
100
Step-by-step explanation:
These two angles are corresponding which means they add up to 180.
so... 19x+5+(16x)=180
If you simplify...
35x+5=180
Then solve for x...
35x=175
x=5
Then take that 5 and fill it into 19x+5...
19(5)+5
95+5=100

Find the linear equation with
Slope= 2/3
y-intercept = 1
Answer:
I believe the answer would be using the form of y= mx+b, b is y intercept and slope is m. It would end up looking like y= 2/3x+1
Step-by-step explanation:
I think this is how a linear equation looks like but I'm a little rusty. If you have notes it probably says what I already stated. Good luck! :)

Answer:
1. [tex]x[/tex] = 9
2. [tex]h[/tex] = 2
3. Infinitely Many Solutions
4. No solution
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
1.) 5(2[tex]x[/tex] + 6) = 8[tex]x[/tex] + 48
Step 1: Expand.
10[tex]x[/tex] + 30 = 8
Step 2: Subtract 30 from both sides.
10[tex]x[/tex] = 8
Step 3: Simplify 8[tex]x[/tex] + 48 − 30 to 8[tex]x[/tex] + 18.
10[tex]x[/tex] = 8
Step 4: Subtract 8[tex]x[/tex] from both sides.
10[tex]x[/tex] − 8
Step 5: Simplify 10[tex]x[/tex] − 8[tex]x[/tex] to 2[tex]x[/tex].
2[tex]x[/tex] = 18
Step 6: Simplify [tex]\frac{18}{2}[/tex] to 9.
[tex]x[/tex] = 9
2.) −3(8 + 3[tex]h[/tex]) = 5[tex]h[/tex] + 4
Step 1: Expand.
−24 − 9[tex]h[/tex] = 5
Step 2: Add 24 to both sides.
−9[tex]h[/tex] = 5
Step 3: Simplify 5[tex]h[/tex] + 4 + 24 to 5[tex]h[/tex] + 28.
−9[tex]h[/tex] = 5
Step 4: Subtract 5[tex]h[/tex] from both sides.
−9[tex]h[/tex] − 5
Step 5: Simplify −9[tex]h[/tex] − 5[tex]h[/tex] to −14[tex]h[/tex].
−14[tex]h[/tex] = 28
Step 6: Divide both sides by −14.
[tex]h[/tex] = [tex]-\frac{28}{14}[/tex]
Step 7: Simplify [tex]\frac{28}{14}[/tex] to 2.
[tex]h[/tex] = 2
3.) 2([tex]y[/tex] − 6) = 3([tex]y[/tex] − 4) − [tex]y[/tex]
Step 1: Expand.
2[tex]y[/tex] − 12 = 3
Step 2: Simplify 3[tex]y[/tex] − 12 − [tex]y[/tex] to 2[tex]y[/tex] − 12.
2[tex]y[/tex] − 12 = 2 − 12
Step 3: Since both sides equal, there are infinitely many solutions.
Infinitely Many Solutions
4.) 8[tex]x[/tex] − 4 = 2(4[tex]x[/tex] − 4)
Step 1: Expand.
8[tex]x[/tex] − 4 = 8
Step 2: Cancel 8[tex]x[/tex] on both sides.
−4 = −8
Step 3: Since −4 = −8 − 4 = −8 is false, there is no solution.
No solution

David has two jobs. He earns $8 per hour babysitting his neighbor's children and he earns $11 per hour working at the coffee shop. If David worked 15 hours at the coffee shop, write an inequality to represent the number of hours, x, babysitting that David will need to work to earn a minimum of $200. Use the inequality to find the number of full hours he must babysit to reach his goal of $200.
Answer:
The number of full hours he must babysit to reach his goal of $200 is 5 hours
Step-by-step explanation:
Let x be the no. of hours he must babysit to reach his goal of $200.
Cost for working 1 hour at coffee shop = $11
Cost for working 15 hour at coffee shop = [tex]11 \times 15=165[/tex]
Cost for working 1 hour babysitting = $8
Cost for working x hour babysitting = 8x
We are supposed to find the number of full hours he must babysit to reach his goal of $200.
165+8x=200
8x=200-165
[tex]x=\frac{200-165}{8}[/tex]
x=4.375
Hence The number of full hours he must babysit to reach his goal of $200 is 5 hours
f(x) =2x-4 and g(x) =-3x+2 find: f(g(x))
Answer:
[tex]f(g(x))=-6x[/tex]
Step-by-step explanation:
Composite Function
Given f(x) and g(x) as real functions, the composite function named [tex](f\circ g)(x)[/tex] is defined as:
[tex](f\circ g)(x)=f(g(x))[/tex]
It can simply be found by substituting g into f.
Our functions are:
[tex]f(x)=2x-4[/tex]
[tex]g(x)=-3x+2[/tex]
Substituting g into f:
[tex]f(g(x))=2(-3x+2)-4[/tex]
Operating:
[tex]f(g(x))=-6x+4-4[/tex]
Simplifying:
[tex]\boxed{f(g(x))=-6x}[/tex]

Fred and Matt are playing basketball. If x represents the points Matt ended with, and 3x represents the points Fred ended with, what does that tell you about the relationship between Matt and Fred’s points?
It tells you that Fred has three times the score more than Matt.
This is because Matt has x points, Fred tops Matt by 3x points.
