What are the intercepts of y=8x-18
Answers
Answer:
\(x-intercept=\frac{9}{4}\)
\(y-intercept=-18\)
Step-by-step explanation:
The y-intercept is where x is equal to 0, and the x-intercept is where y is equal to 0, so:
\(x-intercept=(x,0)\\y-intercept=(0,y)\)
The equation is written in slope-intercept form:
\(y=mx+b\)
m is the slope and b is the y-intercept, so the y-intercept is -18.
Now set the value of y to 0 to find the intercept of x:
\(0=8x-18\)
Solve for x. Add 18 to both sides:
\(0+18=8x-18+18\\18=8x\)
Divide both sides by 8:
\(\frac{18}{8}=\frac{8x}{8} \\\\\frac{18}{8} =\frac{9}{4}\\ \\x=\frac{9}{4}\)
The x -intercept is \(\frac{9}{4}\).
\(x-intercept=(\frac{9}{4},0)\\\\y-intercept=(0,-18)\)
:Done
Step-by-step explanation:
Step 1: Find the y-intercept
To find the y-intercept, you need to set the x-value to 0 and solve for y.
\(y = 8(0) - 18\)
\(y = 0 - 18\)
\(y = -18\)
\((0, -18)\) ← y-int
Step 2: Find the x-intercept
To find the x-intercept, you need to set the y-value to 0 and solve for x.
\(0 + 18 = 8x - 18 + 18\)
\(18 / 8 = 8x / 8\)
\(2.25 = x\)
\((2.25, 0)\) ← x-int

Let's just go through it.
No parallel sides A B C (if you believe the diagram) D F
Not regular (and no parallel sides) (if you believe the diagram) B C D F
No Lines of symmetry (that means that if you put a mirror on a line of symmetry) what you see as an image will be the same as what there is in front of the mirror. C D F
Has a reflex angle. (Just to remind you, it is an angle greater that 180 but less than 360
That lets out everybody but D.
Answer: D
Step-by-step explanation:
1. C and G have one set of parallel sides, and E, H, and I have two sets of parallel sides so they can be ruled out.
2. Regular shapes have sides that are all the same length and angles that all measure the same. A can be ruled out in addition to I which was already ruled out.
3. B can be ruled out now.
4. The only one with a reflex angle (greater than 180 degrees) is D.

Step-by-step explanation:
Hi there!
The perimeter of a figure is the distance around it. To find P, add all the edge measurements:
P = 10+3+33+15+33+3
P = 13+48+36
P = 61+36
P = 97
Therefore, the perimeter of the figure is 97 cm.

What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, John’s age is 12 more than 2 times Sam’s age. The sum of their ages is 65.
Let, The age of Sam be 'x'.
Therefore, 2x + 12 + x = 65.
3x = 53.
x = 17.66.
So, Sam is 17.66 years old and john is (65 - 17.66) = 47.34 years old.

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

Step-by-step explanation:We know that a median is a central tendency of a data and it best represents the given data set.
From the given information we see that the data is skewed to the right since most of the data points takes the higher value and the data is not symmetric as it is skewed.

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.
