Answer:
y=-3x+10
Step-by-step explanation:
Slope formula y2-y1/x2-x1
7-1/1-3
simplify
6/-2
simplify
-3
now plug -3 into y=mx+b
y=-3(x)+b
choose any point and plug it into the equation, I am using (3,1)
1=-3(3)+b
simplify
1=-9+b
add 9 to both sides
b=10
plug into slope-intercept form
y=-3x+10
In how many ways can you answer a 13-question true-false test if you answer each question with either a "true" or a "false"?
Answer:
[tex]\frac{1}{1892}[/tex]
Step-by-step explanation:
There are two possibilities for each of 13 questions, true or false. As a result, you have a [tex]\frac{1}{2}[/tex] chance of choosing either of the choices. To find this, you would multiply the probability to the power of the number of cases, meaning [tex](\frac{1}{2^(13)})=\frac{1}{1892}[/tex].

Answer:
19 degrees.
Step-by-step explanation:
First solve the angles in the top triangle:
FHG = 180 - 135 = 45 (angles on a straight line = 180)
FGH = 180 - 105 = 75 (angles on a straight line = 180)
Using these we get HFG = 180 - 45 - 75 = 60 (angles in a triangle = 180)
Then because HFG is directly opposite DFC on the crossed lines, we know they are equal: DFC = 60
FDC = 180 - 119 = 61 (anges on a straight line = 180)
Now if we label ABC (the target angle) as x then we known ACB = 180 - 40 - x.
With this we know FCD = 180 - ACB = 180 - (180 - 40 - x) = 40 + x (angles on a straight line).
Finally using the FDC triangle we have 40 + x + 60 + 61 = 180 so x = 180 - 40 - 60 - 61 = 19 degrees.
Max and jane had $84 altogether. Max had $6 less than jane. Use algebra to find the amount of money jane had
Answer:
Jane has $45, and Max has $39.
Step-by-step explanation:
M + J = 84
M = J-6
( J - 6 ) + J = 84
2J - 6 = 84
2J = 90
J = $45
M= $39

Caroline uses 9.1 pints of blue paint and white paint to paint her bedroom walls. 1 4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
6.83 pints
Step-by-step explanation:
The first step is to calculate the volume of the blue paint
= 9.1 × 1/4
= 2.275
Therefore the volume of the white paint can be calculated as follows
= 9.1 - 2.275
= 6.83
Hence the volume of white paint that Caroline used to paint her bedroom walls is 6.83 pints
1. Let the side length of each small square on the grid represent 1 unit. Draw two different triangles, e. Ach with base 5 1/2 units and area 19 1/4 units2. 2. Why does each of your triangles have area 1914 units2?
Answer:
Step-by-step explanation:
Given that:
Each small square on a grid represents 1 unit
Base of triangle = 5 1/2 units = 11/2
Area of triangle = 19 1/4 unit² = 77/4
The Area, A of a triangle is obtained thus :
77/4 = 1/2 * 11/2 * h
77/4 = 11/4 * h
h = 77/4 ÷ 11/4
h = 77/4 * 4 /11
h = 7 units

pls explain
Answer:
4 dollars per pair of socks.
Step-by-step explanation:
You already determined that x and y have a proportional relationship, as y is four times the x value. Therefore, when x is 1, that means one pair of socks will be four dollars.
Another way to solve this is by forming a linear equation.
y = 4x
Any number plugged into x to represent pairs of socks will give the cost, y.
For example: y = 4(7), which simplifies to y = 28.
This means that for every one pair of socks, it costs four dollars.
Answer:
yes and $4
Step-by-step explanation:
7*4=28
11*4=44
13*4=52
15*4=60

w*w
6*w
9*w
9*6
[tex]w^2+15w+54[/tex]
Answer: w^2 + 15w + 54
Step-by-step explanation:
FOIL = first, outside, inside, last.
First —> multiply first numbers of each parentheses.
Outside —> multiple the OUTSIDE numbers in each parentheses (first number in the first parentheses, second number in the second parentheses.
Inside —> multiply the INSIDE numbers in each parentheses (the second number in the first parentheses, first number in the second parentheses).
Last —> multiply second number of each parentheses.
(W + 9)(w + 6)
F = w^2
O = 6w
I = 9w
L = 54
W^2 + 6w + 9w + 54
W^2 +15w + 54

Addison and Bert are in the same reading group at school. The book they're reading right now is 256 pages long. Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book. Bert has read 142 pages, and he plans to read 11 pages every day. How many days will it be until Addison and Bert have each read the same number of pages in total? How many pages will they each have read?
Answer: The answer in this photo thanks for a little quiz
The number of day it will be until Addison and Bert each have read the same number of pages in total is 8 days.
What is an equation?In mathematics, an equation is a statement of equality between two expressions, indicated by the equals sign (=). Solutions to equations are the values for unknowns which, when substituted into the expression, make it true.
Given that, the book they're reading right now is 256 pages long.
Let the number of days be x.
Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book.
102+16x -------(i)
Bert has read 142 pages, and he plans to read 11 pages every day.
142+11x -------(ii)
Addison and Bert have each read the same number of pages in total.
So, (i)=(ii)
102+16x=142+11x
16x-11x=142-102
5x=40
x=8
Hence, the number of day it will be until Addison and Bert each have read the same number of pages in total is 8 days.

Write a polynomial in standard form that represents the area of the shaded region.
Answer:
[tex]A=p^2-2p-3[/tex]
Step-by-step explanation:
The area for a triangle is given by:

How many multiples of 5 are there in between 100 and 300?
Answer:
39 multiplesStep-by-step explanation:
Consider AP:
105, 110, ..., 295As multiples of 5 between 100 and 300
The first term is 105, the common difference is 5, the last term is 295.
Use the nth term formula:
105 + 5(n - 1) = 2955(n - 1) = 190n - 1 = 190/5n - 1 = 38n = 39Answer:
Solution given:
first term [a]=100
last term[l]=300
common difference [d]=5
second term[b]=100+5=105
now
we have
l=a+(n-1)d
substituting value
300=100+(n-1)5
300-100=(n-1)5
200/5=n-1
40=n-1
n=40+1
there are 41 multiple in between 100 and 300/including it but no including its 41-2=39 multiple
