PLEASE HELP QUICKLY!!
Answer:
79
Step-by-step explanation:
Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.
what is x + y = -9 in y=mx+b form
Answer: Talk the Talk. Once a linear equation is solved for y, it is in slope-intercept form, y = mx + b. The coefficient of the x term, m, is the slope of the line and the number (or constant), b, is the y-intercept.

4x + 5y = 22
7x - 3y = -32
Answer:
x = -2
y = 6
Step-by-step explanation:
i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out
12x + 15y = 66
+ 35x - 15y = -160
47x = -94
x = -94/47
x = -2
substitute -2 for 'x' to solve for 'y':
4(-2) + 5y = 22
-8 + 5y = 22
5y = 30
y = 6

Pupil who scored 60 in her maths test was absent for English predict what her English mark could have been
Answer:
There is 30% probability for the students who score 60 marks in math.
Step-by-step explanation:
The probability of the students who score 60 marks in math is 30%. There is 70% chance that a student will score less than 60 marks in math. The students who score 60 plus in math will score lesser in English.

what is the distance between (-1, 2) and (5, -2)on a graph put into a decimal form.
Given:
The two points are (-1,2) and (5,-2).
To find:
The distance between the given points.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, the distance between the given points is
[tex]d=\sqrt{(5-(-1))^2+(-2-2)^2}[/tex]
[tex]d=\sqrt{(5+1)^2+(-4)^2}[/tex]
[tex]d=\sqrt{(6)^2+16}[/tex]
[tex]d=\sqrt{36+16}[/tex]
On further simplification, we get
[tex]d=\sqrt{52}[/tex]
[tex]d=7.2111[/tex]
[tex]d\approx 7.21[/tex]
Therefore, the the distance between the given points is about 7.21 units.
x + 3 1/2 = 10 What is the value of x?
Answer:
X = 6 1/2
Step-by-step explanation:
X is equal to 6 1/2 because, if you subtract 3 1/2 from 10 you will be left with 6 1/2.

Answer:
13 x 9 x 5
Step-by-step explanation:
because there is 13 steps in one flight and there fore we need to multiply 13 x 9
then we have to multiply the product by 5 because it is asked how many steps does she climb in five days
if [tex]\sqrt{ 7-y[/tex] = 6 , then y = ?
Answer:
- 29
Step-by-step explanation:
[tex]6^{2}[/tex] = 36

then:
[tex]7 - y = 36[/tex]
[tex]y = -29[/tex]
Nathan is saving up to buy a new phone. He already has $90 and can save an additional $10 per week using money from his after school job. How much total money would Nathan have after 4 weeks of saving? Also, write an expression that represents the amount of money Nathan would have saved in w weeks.
Answer:
$130
Step-by-step explanation:
If Nathan already has $90 then you would add the amount of money collected after the 4 weeks. In each week he makes $10.
The equation would be $90+($10x4)= $X

Step-by-step explanation:
The next four terms should be 16, 32, 64, 128 squares. This is similar to linear functions because, linear functions have a slope that never changes and as you can see here question on E the numbers are doubling and doing it consistently like a linear function
someone pls help:>>
Explanation:
Imagine that you cross out the top-most square for each step of each diagram. The squares not crossed out have the following counts: 1, 4, 9
This is the sequence of perfect squares. So the rule will have us take the number n, and square it to get n^2. Then we add on the squares we crossed out earlier. This explains the "plus 1" at the end to get the answer of n^2+1

A medical equipment industry manufactures X-ray machines. The unit cost C (the cost in dollars to make each X-ray machine) depends on the number of machines made. If x machines are made, then the unit cost is given by the function C(x) = 0.1x2 - 16x +8097. What is the minimum unit cost? Do not round your answer.
Answer:
why cant i round, for example, .9
What is the slope between (2,1); (5,9)
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Answer:
[tex]\frac{8}{3}[/tex]
Step-by-step explanation:
(2, 1)
(5, 9)
Find the slope
____________
When finding slope, we always have to follow the formula :
[tex]\frac{y^2-y^1}{x^2-x^1}[/tex]
The y in the fraction are the second number within the coordinate points, while the exponents are the second number from the second point and the first number from the first point. The same goes for x. Therefore substitute x and y with their corresponding values :
[tex]\frac{9-1}{5-2}[/tex]
[tex]\frac{8}{3}[/tex]

If △ABC∼△LMN and △LMN∼△XYZ, is △ABC∼△XYZ? Use the AA similarity criterion to support your answer.
Answer:
yes because transitive property
Step-by-step explanation:
if abc~lmn, then the angles a and b are similar to angles l and m. and if lmn~xyz then angles l and m are similar to angles x and y. therefore, using transitive property, angles a and b would be similar to angles x and y. so using AA similarity, the two triangles would be similar
