Answer:
d = 6
Step-by-step explanation:
Since the line is horizontal then the distance from B to C is the distance between the x- coordinates.
d = | - 3 - 3 | = | - 6 | = | 6 | = 6
Answer:
option C
Step-by-step explanation:
[tex]distance, d = \sqrt{(x_B- x_C)^2 + (y_B - y_C)^2}[/tex]
[tex]=\sqrt{(-3 -3)^2 + (6 - 6)^2 }\\\\=\sqrt{(-6)^2 + 0 }\\\\=\sqrt{36}\\\\= 6[/tex]

If -10x – 9y = -7 is a true equation, what would be the value of
-30x – 27y?
Answer:
-30x-27y = -21
Step-by-step explanation:
We know that;
-30x-27y = 3(-10x-9y)
Recall, -10x-9y = -7
Thus; -30x-27y = 3(-7) = -21
A triangle has side lengths of (5.5x + 6.2y) cm, (4.3x + 8.3z) cm, and (1.6z - 5.1y) cm. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
9.8x+1.1y+9.9z
Step-by-step explanation:
Hi there!
Perimeter = Sum of all sides
[tex]P=(5.5x + 6.2y)+(4.3x + 8.3z)+(1.6z - 5.1y)[/tex]
Open up the parentheses
[tex]P=5.5x+6.2y+4.3x+8.3z+1.6z-5.1y[/tex]
Combine like terms
[tex]P=5.5x+4.3x+6.2y-5.1y+8.3z+1.6z\\P=9.8x+1.1y+9.9z[/tex]
Therefore, the expression 9.8x+1.1y+9.9z (cm) best represents the perimeter of the triangle.

Find the interior angle sum for each polygon. Round your answer to the nearest tenth if needed
(#4 and #3 are solve for x)
Answer:
1) 720
2) 540
3) x = -1
4) x = 10
Step-by-step explanation:
The formula for finding the sum of interior angles in a polygon is the following,
[tex]S=180(n-2)[/tex]
Where (S) represents the sum of interior angles, and (n) represents the number of sides.
1)
The given polygon is a hexagon, meaning it has (6) sides. Substitute the number of sides into the formula and solve for the sum of interior angles.
[tex]S=180(n-2)[/tex]
[tex]S=180(6-2)\\\\S=180(4)\\\\S = 720[/tex]
2)
This polygon is a pentagon, meaning it has (5) sides. Substitute the number of sides into the formula and solve for the sum of interior angles.
[tex]S=180(n-2)[/tex]
[tex]S=180(5-2)\\\\S=180(3)\\\\S=540[/tex]
3)
The sum of interior angles in a triangle is (180) degrees. One can see that one of the measures of an angle is (90) degrees (indicated by the box around the angle). One can form an equation by adding up the expressions for the angle measures and setting it equal to (180) degrees.
(55) + (x + 36) + (90) = 180
Simplify,
181 + x = 180
Inverse operations,
181 + x = 180
x = -1
4)
The remote angles theorem states that when one extends one of the sides of a triangle, the angle formed between the side and the extension is equal to the sum of the two non-adjacent interior angles in the triangle. Based on this theorem, one can form an equation and solve for the unknown.
<F + <G = <FEZ
Substitute,
(4x) + (-5 + 7x) = 105
Simplify,
4x - 5 + 7x = 105
11x - 5 = 105
Inverse operations,
11x - 5 = 105
11x = 110
x = 10

The Chang family is on their way home from a cross-country road trip. During the trip, the function D(t)=3260−55t can be used to model their distance, in miles, from home after t hours of driving. find D(12) and interpret the meaning in the context of the problem.
Answer:
D(12) = 2,600 miles
It means a distance of 2,600 miles is already traveled from home after 12 hours
Step-by-step explanation:
To find D(12); all we have to do is to substitute the value of 12 for D
We have this as;
D(12) = 3260-55(12)
D(12) = 2,600
In the context of this problem, what this mean is that the distance away from home is 2,600 miles after traveling 12 hours

The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions shown below represent the sale price, in dollars,of the item.Expression A: Expression B: Expression C: Expression D: Expression E: Which two expressions each represent the sale price of the item?AExpression A and Expression EBExpression B and Expression CCExpression B and Expression DDExpression C and Expression D
Answer:
Expression B: 0.8p
Expression D: p - 0.2p
Step-by-step explanation:
The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions shown below represent the sale price, in dollars, of the item.
Expression A: 0.2p
Expression B: 0.8p
Expression C:1 - 0.2p
Expression D: p - 0.2p
Expression E: p - 0.8p
Which two expressions each represent the sale price of the item?
Regular price of the item = $p
Sale price = 20% off regular price
Sale price = $p - 20% of p
= p - 20/100 * p
= p - 0.2 * p
= p - 0.2p
= p(1 - 0.2)
= p(0.8)
= 0.8p
The sale price is represented by the following expressions
Expression B: 0.8p
Expression D: p - 0.2p

Answer:
Step-by-step explanation:
sams house=6 miles east and 9 mies south
let the distance towards east be a and distance towards south be b
so we have to find straight line distance from sams house to amys house .let it be c(or hypotenuse)
according to the pythagors theorem
a^2 + b^2 =c^2
6^2 + 9^2 =c^2
36 + 91 =c^2
117 =c^2
[tex]\sqrt{117[/tex] =c
10.8=c
the two coordinate points are
(4,12)=(x1 , y1)
(6,2)=(x2 , y2)
distance formula = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
=[tex]\sqrt{(6-4)^2 + (2-12)^2}[/tex]
=[tex]\sqrt{2^2 + (-10)^2}[/tex]
=[tex]\sqrt{4 + 100}[/tex]
=[tex]\sqrt{104}[/tex]
=2[tex]\sqrt{26}[/tex]
=10.1 units
fairy travels=10.1 * 2
=20.2 miles
three sides are 17,8,15
according to the pythagoras theorem
to be right angles triangle square of hypotenuse(longest side) must equal to the sum of square of two other smaller sides
so here 17 is longest and 8 and 15 are two other smaller sides of a triangle
17^2=8^2 + 15^2
289=64 + 225
289=289
since both sides are equal it can be concluded that they form a right angled triangle.

Step-by-step explanation:
Step 1: Set Up System of Equations
[tex]a + b = 13[/tex]
[tex]ab = 40[/tex]
Solve for a in the first equation
[tex]a = 13 - b[/tex]
Subsitur that in for the 2nd equation

Think of a number that adds to 13 and multiply to 40.
Th
[tex]b = 5[/tex]
[tex]b = 8[/tex]
So the answer is 5 and 8. Remember factos are interchangeable so a and b can be either 8 or 5.

Step 1: Simplify both sides of the equation.
[tex]5(z+1)=3(z+2)+11 \\ (5)(z)+(5)(1)=(3)(z)+(3)(2)+11(Distribute) \\
5z+5=3z+6+11 \\
5z+5=(3z)+(6+11)(Combine Like Terms) \\
5z+5=3z+17 \\
5z+5=3z+17[/tex]
Step 2: Subtract 3z from both sides.
[tex]5z+5−3z=3z+17−3z \\ 2z+5=17[/tex]
Step 3: Subtract 5 from both sides.
[tex]2z+5−5=17−5 \\ 2z=12[/tex]
Step 4: Divide both sides by 2.
[tex] \frac{2z}{2} = \frac{12}{2} \\ z = 6[/tex]

I've been learning this but I don't remember how to find x?
Answer:56 degrees
Step-by-step explanation: Using Base Angles Theorem, we can conclude that angle x is 180-62*2, which is 180-124, which is 56 degrees.
Answer:
the answer is x = 56 degrees
and your not finding the side lengths
Step-by-step explanation:
there is 2 62 degrees,
meaning the TOP RIGHT ANGLE OF THE TRIANGLE IS 62 DEGREES if you can't find it in my answer and X IS EQUAL TO THE ANGLE OF 56 DEGREES if you can't read that either
so x = 56
Use a graph to tell whether the ordered pairs represent a linear function, an exponential
function, or a quadratic function.
(-2, 2), (-1, 5), (0, 3), (1, 1) (2, 3)
Answer: exponential function
Step-by-step explanation:
Graph it.
You will see that the ordered pairs make the shape of a sideways "S."
Linear functions are straight lines and quadratic functions are "U" or upside-down "U" shaped curves. Exponential functions can have multiple curves like including a sideways "S" shape, so it is exponential.
