X has to be more than 9. 9+8=17, which would be a straight line.
X has to be less than 25. 17+8=25, which would be a straight line.
Answer:
9 < x < 25
Step-by-step explanation:
The length of a side of a triangle must be greater than the difference between the lengths of the other sides and less than the sum of the lengths of other sides.
x must be greater than the difference between 17 and 8.
17 - 8 = 9
x > 9
x must be less than the sum of 17 and 8.
x < 17 + 8
x < 25
When you put the two inequalities above together, you get:
9 < x < 25

Write an equation that passes through a minimum
point of (-3,-2) and a y-intercept at (0,25)
Answer: y= 9x+ 25
Step-by-step explanation:
to calculate the slope, rise/run rise is difference in y-values 25 -(-2) =27
run is difference in x-values 0-(-3) = 3 . 27/3 = 9

A grocery store sells 6 ears of corn for $3.54. Which of the fllowing shows how to find the amount of money that each ear of corn costs at the grocery store?
a
$3.54 x 6
b
6 ÷ $3.54
c
6 - $3.54
d
$3.54 ÷ 6
Answer: B: 6÷3.54
Step-by-step explanation: Since they sold 6 ears and made $3.54 total, you would have to divide 6 by $3.54 to determine the cost of each ear.

The radius of the circle shown below is 3 inches.
What is the area of this circle, in square inches?
Answer:
the area = 28.27 or you can write the answer out as 28.2744 or also 28.27433
Step-by-step explanation:
start with what we know. the formula for solving this is A=pi R squared
so, area= pi (3.1416)
then, multiply that by the radius given, which is 3.
So, 9.4248 × 3 = 28.2744 square inches
or 28.27 sq.in.

Given mn, find the value of x.
Answer:
x = 117°
Step-by-step explanation:
x and 63° are "Same Side Exterior Angles". These angles are supplementary.
Hence: x + 63 = 180
x = 180 - 63
x = 117°
Graph a line with a slope of -5 that contains the point (-3,-4)
We want to graph a line with a slope of -5 that contains the point (-3, -4), the graph can be seen at the end.
Getting the equation:
We first need to get the equation of the line that we must graph.
The general line equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
Here we know that the slope must be -5, so we have:
y = -5*x + b
And we know that it must contain the point (-3, -4), then we can replace these values for x and y in the equation and solve it for b:
-4 = -5*-3 + b
-4 = 15 + b
-4 - 15 = b
-19 = b
Then the linear equation is:
y = -5*x - 19
To graph this you just need to find two points on the line and then connect them with a line, we already know one (-3, -4). To get another we can evaluate the equation in any value of x, for example with x = 0 we get:
y = -5*0 - 19
y = -19
Then the other point is (0, -19)
With these two points you will get the graph below:

[tex]\displaystyle 5x + y = -19\:or\:y = -5x - 19[/tex]
Step-by-step explanation:
Plug the information into the Slope-Intercept Formula:
[tex]\displaystyle y = mx + b \\ \\ -4 = -5[-3] + b \hookrightarrow -4 = 15 + b; -19 = b \\ \\ y = -5x - 19[/tex]
Suppose you need to write this equation in standard form. You would follow these procedures:
y = −5x - 19
+ 5x + 5x

Henry's Jewelry Store receives a shipment of 500 jewelry pieces, but 15 pieces are damaged. At this rate, if Henry's Jewelry Store places an order for 5,500 jewelry pieces, how many should they expect to be damaged? They should expect pieces of jewelry to be damaged.
Answer:
They should expect 165 damaged pieces in 5500 jewelry pieces
Step-by-step explanation:
The first thing we need to do is to get some metrics to measure the rate at which the damaged jewelry is seen.
We can use 15 pieces of jewelry that are damaged for every 500 ordered.
Once this is done, we can then use this to estimate how many pieces of jewelry are damaged if 5,500 are ordered.
We now need to know how many sets of 500 pieces of Jewelry are in 5,500.
This is 5,500/ 500 = 11 sets
Therefore, all 11 sets will have 15 damaged pieces of jewelry each. The total number of damaged jewelry pieces will be 15 X 11 = 165 damaged pieces

Step-by-step explanation:
I have a bag containing red, green, blue, and white marbles and the ratio $\text{red}:\text{green}:\text{blue}:\text{white}$ is $2:2:5:7$. I have 304 marbles. How many blue marbles do I have?
Answer:
95
Step-by-step explanation:
Let 2x be how many red/green marbles there are,
let 5x be how many blue marbles there are, and
let 7x be how many white marbles there are.
2x + 2x + 5x + 7x = 304
16x = 304
x = 19
As 5x is defined as how many blue marbles there are, we could just plug x for 19:
5*19 = 95
I hope this helped, and if it did please consider giving me brainliest :)
Answer:
95
Step-by-step explanation:
Let r, g, b, w be the number of red, green, blue, and white marbles, respectively. Since r : g : b : w = 2 : 2 : 5 : 7, there is some value of x for which r = 2 x, g = 2x, b = 5x, and w = 7x. Then, we have
304 = r + g + b + w
= (2x) + (2x) + (5x) + (7x)
= 16x
Dividing both sides of 16x = 304 by 16 gives x=19. This gives us r = 38, g = 38, b = 95, w = 133, so I have 95 blue marbles.
