Answer:
slope is -2/1
Step-by-step explanation:
when you find slope of a line, its rise over run
so when ever the line hits a point, it goes 2 down and 1 right (if you explain this simply)
Answer:
m= -2
Step-by-step explanation:
The two points are 0,2 and 1,0 and the equation used between them spits out -2

Here’s an algebra problem given 20 points and brainliest if correct
Answer:
12/7
Step-by-step explanation:
Hello,
C is the point (0,0)
D is the point (7,12)
So
[tex]\text{slope} =\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{12-0}{7-0}=\dfrac{12}{7}[/tex]
thanks
Answer:
12/7 possibly.
Step-by-step explanation:
Point C is (0,0) and point D is (7,12). Using the formula given, You should have something that looks like this:
[tex]\frac{(12-0)}{(7-0)}[/tex]
Then you solve:
[tex]\frac{12}{7}[/tex]
That would be your answer I believe.
I hope it helps.

Two angles form a linear pair. The measure of one angle is 1/3 of the other angle. Find the measure if each angle
Answer:
The measure of the angles is 45° and 135°
Step-by-step explanation:
When two lines intersect, a linear pair of angles is formed. Two angles are said to be linear if they are adjacent, so a linear pair of angles must add up to 180 degrees.
Let's call x and y the two required angles. Knowing they form a linear pair:
x+y=180
We also know one angle is 1/3 of the other angle, thus:
x=y/3
Or, equivalently:
3x=y
Substituting y into the first equation:
x+3x=180
Simplifying:
4x=180
Solving:
x=180/4=45
The other angle is:
y=3x=3\cdot 45=135
Thus the measure of the angles is 45° and 135°
Chad and his two friends are picking blueberries at a local farm. Chad picked 2 pounds of blueberries, and one of his friends picked 1 pounds. If they ended up with a total of 5 pounds, how many pounds did Chad's other friend pick? Express your answer as a mixed number.
Answer:
Chad's other friend pick 2 pounds of blue berries.
Step-by-step explanation:
Chad picked 2 pounds of blue berries.
One of his friends picked 1 pound of blue berries.
Totally there is 5 pounds.
So, other friend picked blue berries = 5-2-1 =2 pounds
We get answer as whole number. So no need to write it in mixed form.

*see attachment below for the figure referred to
Answer:
*The measure of angle <CBA is equal to the measure of angle <DBE.
*The measure of angle CBD is equal to the measure of angle ABE.
*The sum of the measures of angles CBD and CBA is 180 degrees.
Step-by-step explanation:
Since lines CE and AD bisects at D, they form two pairs of vertical angles that are congruent to each other. The vertical angle pairs formed are:
<CBD and <ABE;
<CBA and <DBE
Thus:
m<CBD = m<ABE;
m<CBA = <DBE = 37°
Also, m<CBA + m<CBD = 180° (supplementary linear pair)
m<ABE + m<DBE = 180° (supplementary linear pair)
Therefore, the following statements are TRUE:
*The measure of angle <CBA is equal to the measure of angle <DBE.
*The measure of angle CBD is equal to the measure of angle ABE.
*The sum of the measures of angles CBD and CBA is 180 degrees.

Solve for x2:
y2 − y1 = m(x2 − x1)
this is literal equations btw
Answer:
x2 = y2/m - y1/m + x1
Step-by-step explanation:
Expand
y2 - y1 = mx2 - mx1
Rearrange
y2 - y1 + mx1 = mx2
Divide both sides by m to make x2 on its own
y2/m - y1/m + x1 (m's cancel out) = x2
Hence:
x2 = y2/m - y1/m + x1
Answer:
x2 = x1 + (y2 - y1)/mStep-by-step explanation:
Given equation
y2 − y1 = m(x2 − x1)Solving for x2
y2 − y1 = m(x2 − x1) ⇒ divide both sides by m(y2 - y1)/m = x2 - x1 ⇒ add x1 to both sidesx2 = x1 + (y2 - y1)/mor
x2 = x1 + y2/m - y1/mMddffffvcfffff ggbtevtrvyrvyr eg rh rhbrybryvr th tu rybry th th ht

a cookie recipe uses 5/6 cups of sugar lindsey is making 1 1/2 times what the recipe calls for how much sugar is she using
Answer:
1 1/4 cups of sugar
Step-by-step explanation:
5/6 x 1 1/2 = 1 1/4
Answer:
5/4 cup of sugar.
Step-by-step explanation:
The recipe calls for 5/6 of a cup of sugar, so if you're making 1.5 times what the recipe calls for, you multiply 5/6 by 3/2 (or 1.5 if you prefer decimals) which would give you 15/12. Then simplify down to get 5/4 (or 1.25) cups of sugar.
Note: 5/4 also equals 1 1/4, they are both correct, it just depends on which way you choose to write it, or how your teacher wants you to write it.

Answer:
f(3) = -9
Step-by-step explanation:
Given that,
→ f(x) = -7x + 12
Then the value of f(3) will be,
→ f(3) = -7(3) + 12
→ f(3) = -21 + 12
→ [ f(3) = -9 ]
Hence, the value is -9.

i did the edge test, i got it right. trust me, i dont lie. :) have a nice day<3
proof:
Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing, what would the inequality be?
The inequality is 0.75x greater than or equal to y
Step-by-step explanation:
Given : Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing.
To find : Which inequality represents this situation?
Solution : He plays trumpet for a minimum of 45 minutes
If x is the number of days that Lionel practices then he practices for at least
hours
y is the total number of hours he spends practicing
So, the inequality form is:
i.e, 0.75x is greater than y.
