Answer:
[tex]x-intercept=\frac{9}{4}[/tex]
[tex]y-intercept=-18[/tex]
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:
[tex]x-intercept=(x,0)\\y-intercept=(0,y)[/tex]
The equation is written in slope-intercept form:
[tex]y=mx+b[/tex]
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:
[tex]0=8x-18[/tex]
Solve for x. Add 18 to both sides:
[tex]0+18=8x-18+18\\18=8x[/tex]
Divide both sides by 8:
[tex]\frac{18}{8}=\frac{8x}{8} \\\\\frac{18}{8} =\frac{9}{4}\\ \\x=\frac{9}{4}[/tex]
The x -intercept is [tex]\frac{9}{4}[/tex].
[tex]x-intercept=(\frac{9}{4},0)\\\\y-intercept=(0,-18)[/tex]
: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.
[tex]y = 8(0) - 18[/tex]
[tex]y = 0 - 18[/tex]
[tex]y = -18[/tex]
[tex](0, -18)[/tex] ← 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.
[tex]0 + 18 = 8x - 18 + 18[/tex]
[tex]18 / 8 = 8x / 8[/tex]
[tex]2.25 = x[/tex]
[tex](2.25, 0)[/tex] ← x-int
Let X = {1, 2, 3, 4, 5, 6, 7, 8, 9}, y = {0, 2, 5, 8, 12, 13, 17, 19}, and Z = {z|z is an even integer less than 19}. Find X ∩ Y ∩ Z.
A. {2, 4, 6, 8}
B. {all whole number < 20}

Find the value of z. Use 3.14 for pie
Answer: 6
Step-by-step explanation: You can make this question into an algebraic expression. This is basically 3.14x(z^2)x15=1696.5. If you divide 1696.5 with 15, you get 3.14x Z x Z=113.1. If you divide 113.1/3.14, you get about 36, and the square root of 36 is equal to 6.

Here is a list of numbers:
17,6,-10,-7, -12,-12, -2, 16, -14
State the median.
Put the numbers from least to greatest.
17, 6, -10, -7, -12, -12, -2, 16, -14 → -14, -12, -12, -10, -7, -2, 6, 16, 17
The median is the middle number of a data set.
-14, -12, -12, -10, -7, -2, 6, 16, 17
Therefore, the median is -7.
Best of Luck!
Find the volume of the triangular prism described below.
The base is a 45°-45°-90° triangle with a leg of 4 in. The height is 1.7 in.
A 45-45-90 triangle has two legs that are the same length. So both legs are 4 in.
Area of the triangle = 1/2 x 4x4 = 8 square in.
Volume = 8 x 1.7 = 13.6 cubic inches.

1 hundredth + 3 tenths = how many hundredths
Answer:1 hundredths
Step-by-step explanation:One-tenth equals 0.1 and one-hundredth equals 0.01, which means that hundredth equals 10 hundredths. The conversion is the same no matter which unit you are using. You might need to convert from tenths to hundredths if you have one measure in tenths and another in hundredths and want to compare the two.
From the equation above;
1 hundredth + 3 tenths = 31 hundredths
According to the question;
We are required to evaluate; 1 hundredth + 3 tenths = how many hundredths.By place value;
1 hundredth = 1 × 0.01 = 0.013 tenths = 3 × 0.1 = 0.3The addition of both yields;
0.01 + 0.3 = 0.31In essence; since 0.01 = 1 hundredth Then 0.31 = (0.31 ×1)/0.01= 31 hundredths.Read more;

[tex](2.7 * 10^{5} ) / (9 * 10^{6})[/tex]
Answer:
3 * 10 ^-2
Step-by-step explanation:
When we divide numbers in scientific notation first divide the number portion
2.7 /9 =.3
Then divide the exponents
10 ^5 / 10 ^6 = 10 ^ (5-6) = 10 ^ -1
.3 * 10 ^-1
We cannot leave the .3 since the first number has to be between 1 and less then 10
Move the decimal 1 place to the right which means subtract 1 from the exponent
3 * 10 ^-2
Answer:
0.03
Step-by-step explanation:
Hello there! Lets get started!
Now, with this problem as simple as it is, there are multiple ways we could solve it! If you have a scientific or graphing calculator, you could easily plug it in as it is! If you just have a four-function calculator, you could still solve it! Or, You could get advanced with log functions and such, but that is not needed at all for this function.
I am going to assume that you only have access to a four-function calculator, so lets begin!
First, we need to expand our numerators and denominators beyond scientific notation!
When dealing with positive scientific notation, you are moving your decimal to the right (I am not going to fully explain how to expand scientific notation, we are just going to move the decimal).
With 2.7 x [tex]10^{5}[/tex], we will move the decimal 5 places to the right!
With 9.0x [tex]10^{6}[/tex], we will move the decimal 6 places to the right!
This gives us 270000 and 9000000!
Now lets solve 270000 ÷ 9000000!
This gives us a final answer of .03!
Hope this helps! Remember, math is fun!

If 5% of an amount equals 800,000, then what is that amount? Please I confused, can someone help me!
Answer:
the amount is 16,000,000
Step-by-step explanation:
first let that amount be Y for an example. so...
[tex]\frac{5}{100}*Y=800,000[/tex]
[tex]\frac{5Y}{100}=800,000[/tex]
[tex]5Y=800,000*100[/tex]
[tex]5Y=80,000,000 (then you both divide by 5 in both sides so that Y is left alone.)[/tex]
[tex]So Y=16,000,000[/tex]
so the amount you are looking for is 16,000,000

If CB = 6, GF = 3, and CD = 4, find GH.
A) 2
B) 3
C) 8
D) 10
Answer:
a
Step-by-step explanation:
CB and GF are the same side and u can see that CB is two times larger than GF so GH is two times smaller then CD
The solution is, the value of GH = 2, option A.
What is scale factor?A scale factor is when you enlarge a shape and each side is multiplied by the same number. This number is called the scale factor. Maps use scale factors to represent the distance between two places accurately.
here, we have,
If CB = 6, GF = 3, and CD = 4,
and, we have to find GH.
from the given figures we get,
CB and GF are the same side and u can see that CB is two times larger than GF so GH is two times smaller then CD.
i.e. CB/GF = 6/3 = 2
scale factor = 2.
again, CD/GH = 2
So, GH = CD/2
=2
Hence, The solution is, the value of GH = 2.

What is the probability that a randomly-chosen student from this group did not take exactly two subjects?
Answer:
[tex]\dfrac{118}{135}[/tex]
Step-by-step explanation:
Total Number of Students =135
Number who took all three subjects=5
Number who took PE and BIO=10
Number who took PE and ENG=15
Number who took BIO and ENG=7
Therefore:
Number who took PE and BIO only=10-5=5Number who took PE and ENG only=15-5=10Number who took BIO and ENG only =7 -5=2Total Number of students who took exactly two subjects=5+10+2=17
Therefore:
Number of students who did not take exactly two subjects=135-17=118
The probability that a randomly-chosen student from this group did not take exactly two subjects
[tex]=\dfrac{\text{Number of students who did not take exactly two subjects}}{\text{Total Number of students }} \\=\dfrac{118}{135}[/tex]
