Answer:
On a coordinate plane, a line has a negative slope
Step-by-step explanation:
If a graph only shows one line, there is an infinite amount of solutions. We need two separate line equations to cross at a point in order to find the solution to the system. However, if a graph shows two parallel lines that never cross, there are no solutions to that systems of equations.
Answer:
The correct answer is the last graph (C).

Which expression is equivalent to 2^5(4×+9)
Answer:
128x + 288
Step-by-step explanation:
Given the expression 2^5(4×+9)
on factoring
2^5(4×+9) = 2^5(4x) + 2^5(9)
2^5(4×+9) = 32(4x) + 32(9)
2^5(4×+9) = 128x + 288
Hence the expression is also equivalent to 128x + 288

Please help ;-;..................................
Answer:
12.9 - 22.7b
Step-by-step explanation
Given the expression 4.3(3-5b) = 1.2b
Open the bracket
4.3(3-5b) = 1.2b
4.3(3)-(4.3)(5b) = 1.2b
12.9 - 21.5b = 1.2b
12.9 - 21.5b - 1.2b
12.9 - (21.5+1.2)b
12.9 - 22.7b
Hence the required expression is 12.9 - 22.7b
The average temperature of the week is 80 degrees. The first 3 days have an average of 78 and the average of the last 3 days is 82 degrees, what was the temperature of the middle day?
Answer:
80
Step-by-step explanation:Solution:
step 1 Address the formula, input parameters & values.
Input parameters & values:
The given numbers are 78 & 80
step 2 Find the sum of the given two numbers.
sum = 78 + 80 = 158
step 3 Divide the sum by 2 to get the average.
average = 158/2
= 79
Thus, 79 is an average of positive integers 78 and 80.
GETS BRAINLIEST AND 30 POINTS ! Describe the dilation of a line segment by a scale factor of 1/2 centered at the origin
Answer:
Following are the solution to this question:
Step-by-step explanation:
A transform is a dilation that has changed the size and shape of such a geometric form.
Segment of let line is:
[tex]\to x_i=x_n+t(x_{n+1} -x_n)\\\\\to y_i=y_n+t(y_{n+1} -y_n)[/tex]
[tex]scale \ factor = \frac{1}{2}[/tex]
The dialling is based on its origin and also the line section, in order to provide new coordinates [tex](\frac{x_n}{2}, \frac{y_n}{2}) , (\frac{x_{n+1}}{2}, \frac{y_{n+1}}{2})[/tex] So, the line segment is unchanged, and also has shorter.

Answer:
Blank 1: 28
Blank 2: 42
Blank 3: 22
Answer: It will take 7 sessions.
Step-by-step explanation:
We already know the 3 blanks from the equation 28x = 42 + 22x
Now to find the answer.
28x = 42 + 22x
Subtract 22x from both sides. This cancels the +22x.
28x - 22x = 42
Subtract 22x from 28x to get 6x
6x = 42
Divide both sides by 6. This undoes the multiplication by 6.
x = 42/6
Divide 42 by 6 to get 7.
x = 7
It will take 7 sessions for the costs to match.

I need to know then measurement of c
Answer:
[tex] \huge{ \boxed{ \bold{ \sf{ \pink{80°}}}}} [/tex]
Step-by-step explanation:
✰ [tex] \underline{ \sf{First, \: Let's \: learn \: about \: internal \: angles \: of \: a \: triangle}}[/tex]
The angles which are formed inside by the joining of arms of a triangle is called interior angles of a triangle. According to the figure provided , In ∆ ABC , ∠ABC , ∠ ACB , ∠ BAC are interior angles because they lie inside the ∆ ABC and sum of such interior angles is always 180°.
❀ [tex] \sf{Now, \: Let's \: solve} : [/tex]
☄ [tex] \underline{ \underline{ \sf{Provided : }}}[/tex]
∠B = 3x°∠ C = 4x°∠ A = 2x°☄ [tex] \underline{ \sf{To \: Find :}}[/tex]
Measure of C✏ [tex] \text{Set \: up \: an \: equation \: and \: solve \: for \: x.}[/tex]
[tex] \text{{∠a \: + \: ∠ \: b \: + \: ∠ \: c \: = \: 180 \degree}}[/tex]
→ [tex] \sf{2x + 3x + 4x = 180 \degree}[/tex]
→ [tex] \sf{9x = 180 \degree}[/tex]
→ [tex] \sf{ \frac{9x}{9} = \frac{180 \degree }{9} }[/tex]
→ [tex] \sf{x = 20 \degree}[/tex]
The value of x is 20°. As we are asked to find the measure of ∠C , substituting the value of x in 4x :
[tex] \text{∠c = 4x}[/tex]
→ [tex] \sf{∠ \: c \: = 4 \times 20 \degree}[/tex]
→ [tex] \boxed{ \bold{ \pink{ \sf{∠c \: = 80 \degree}}}}[/tex]
Hence , The measure of ∠ C is 80 °

What is the area of the base?
Answer:
40
Step-by-step explanation:
work out the median 8, 6, 4, 5, 9,8
Answer:
7
Step-by-step explanation:
the median is the middle and if you order them
4,5,6,8,8,9 then you remove one from each side until you have 6,8 so you go in-between the two (seven)
Answer:
7
Step-by-step explanation:
You need to arrange the numbers in an increasing order:
4 5 6 8 8 9
then you need to count how many values we have in the specific set:
6 total values
now we need to find the middle of our set
4 5 6 II 8 8 9
and then we divide the two numbers next to the middle part (6;8) and divide them by 2
(6+8):2=7

A hot air ballon went from an elevation of 6,669 feet to an elevation of 3,402 in 54 minutes. What was its rate of descent?
Answer:
elevation refers to the height of the balloon. Descent refers to moving down, and rate of descent refers to how quickly the balloon moved down.
In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.
That means that the balloon traveled downward 62.5 feet every minute. That's a fast moving balloon!
