Please helppppppppppppppppp
Answer:
Step-by-step explanation:
1)
a/c =b/d where a=27 c=30 b=x d=18
27/30 = x/18
27*18/30=x
16.2 = x
2)
a/c =b/d where a=2x-5 c=x+11 b=16 d=14
2x-5 / x + 11 = 16 / 14
14(2x-5) = 16(x+11)
28x - 70 = 16x + 176
12x = 246
x = 20.5
3)
6+15 / 7+x = 7 /6
6(6+15) = 7(7+x)
6*21 = 49 +7x
126 = 49 +7x
77 = 7x
11 = x
4)
3*[(x-6)+3]=[tex]6^{2}[/tex]
3(x-3) = 36
3x-9 = 36
3x = 45
x = 15

Which piecewise function is shown on the graph?
Answer:
Option A
Step-by-step explanation:
Just substitute each value of x in the graph to find the correct function.
When be graph the functions given, we find that option A is correct.
What is meant by to graph a function?To graph a function, you have to select x-values and plug them into the equation. Once you plug those values into the equation, you will get a y-value. Your x-values and your y-values make up your coordinates for a single point. Keep plugging in x-values to get coordinates to plot more points on the graph, and then you will see your graphed function once the dots are connected.
Using the graph,
For x < = -2, y = 5.
For -2 < x < 1, the function is a polynomial.
We have two options, either [tex]y = x^{2} -5\ or\ y = x^{2} +5[/tex]
The polynomial must have the point (0,-5) on it.
For [tex]y = x^{2} -5[/tex] , when x = 0, y = -5.
Hence, it is the correct option.
For x >= 1,
Using graph, we see that when y = 0, x lies between 3 and 4.
For equation, [tex]y = 2^{(x-2)} - 2\\[/tex], when y = 0, x = 3, so it is not correct.
For equation, [tex]y = 2^{(x-2)} - 3\\[/tex], when y = 0, x = 3.584, hence it is correct.

Plz help! Sam had an appointment 90 miles away from home at 2pm. He drove there at 60 mph, and was 15 minutes late. What time did Sam start driving at?
Example: 1:50
Answer:
12:45 pm
Step-by-step explanation:
First we find out the amount of time it takes to drive 90 miles at 60 mph.
speed = distance/time
time * speed = distance
time = distance/speed
time = 90 miles / 60 mph
time = 1.5 hour = 90 minutes
It takes 1.5 hour, or 90 minutes, to drive 90 miles at a speed of 60 mph.
To get there at 2:00 pm, he should have left at 12:30 pm.
He got there 15 minutes late, so he must have left 15 minutes late.
He left at 12:45 pm.

What is the difference between greatest common divisor and greatest common denominator ?
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators
Look at the inequality.
3y > 27
Which set of values for y will make this inequality true?
A. 4,5,8
B. 5, 7,9
C9, 12, 14
D. 11, 13, 22
Answer:
D) 11,13,22
Step-by-step explanation:
If 3y>27, then y>9. Therefore, D is the correct answer (C is not correct BTW because 9 isn't included in the inequality).
Does the following equation, y= -x2 -10x +1 have a maximum or
minimum. Explain
Answer:
Step-by-step explanation:
Your y= -x2 -10x +1 should be written as y = -x^2 -10x +1. This is a quadratic function. Because the coefficient (-1) of the x^2 term is negative, we know immediately that the graph (a parabola) opens down, and thus has a maximum.
Which equation represents the graph ?
Answer:
The equation of the line is;
y + 4 = 3(x + 4)
Step-by-step explanation:
The general equation of a line is;
y = mx + b
where m is the slope and b is the y-intercept
To get the equation, let us look at the given intercepts
We have the intercepts at the point (0,5) and (-2,-1)
We have the slope of the line as follows;
m = (y2-y1)/(x2-x1) = (-1-5)/(-2-0) = -6/-2 = 3
So we have the equation as;
y = 3x + b
recall, we have the y-intercept as 5
so the complete equation is;
y = 3x + 5
Now, we can rewrite this as;
y+ 4 = 3(x + 3)

2. Find 2 solutions to -X > 10
The two solutions of the inequality -X > 10 are -15 and -11
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
To solve the inequality -X > 10, we need to isolate the variable X on one side of the inequality.
We can start by multiplying both sides of the inequality by -1 to get:
X < -10
This means that any value of X that is less than -10 will satisfy the inequality.
Therefore, two possible solutions to the inequality are:
X = -15 (since -15 is less than -10, the inequality -X > 10 is true)
X = -11 (since -11 is also less than -10, the inequality -X > 10 is true)
Note that there are infinitely many possible solutions to the inequality, since any value of X that is less than -10 will work.
Hence, the two solutions of the inequality -X > 10 are -15 and -11

Which fractions are equivalent to -15/4? Select all that apply. A: -15/4 B:-15/-4 C:15/-4 D:15/4 E:- 4/15 F:4/-15
Answer:
-15/4
C:15/-4
Step-by-step explanation:
a negative number divided by another negative number gives a positive number : -15 / - 4 = +3.75
-15/4 and 15/-4 = -3.75
15/4 = 3.75 (two positive numbers divided with each other yields a positive number)
-4/15 and 4 / -15 = 0.27

Find the area of the shape
Answer:
54 unit^2.
Step-by-step explanation:
The area = the sum of the 2 triangles.
Area of a triangle = 1/2 * base * height.
So here:
A = 1/2 * 4 * 12 + 1/2 * 5 * 12
= 24 + 30
= 54
Answer:
ABCD = 54 u²Explanation:
the area of the polygon = the area of the triangle ADC + the area of the triangle ABC
the area of a triangle = (height × base)/2
A ADC = (DE×AC)/2
A ADC = (4×12)/2
A ADC = 48/2
A ADC = 24 u²
A ABC = (BF×AC)/2
A ABC = (5×12)/2
A ABC = 60/2
A ABC = 30 u²
ABCD = A ADC + A ABC
ABCD = 24 + 30
ABCD = 54 u²
