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
When do you use a Vertex Form y=a(x – h)2 + k ? What information do you get from a Vertex Form?
Please tell me
y = a(x - h)² + k is the vertex form of an equation of a parabola with vertex (h,k)
We get the coordinates of the vertex of parabola from that form: (h, k)
We also know if the parabola goes up or down: a>0 or a<0
We can tell how many roots has the equation:
(a>0 and q>0) or (a<0 and q<0) ⇒ no roots
a≠0 and q=0 ⇒ one root: x₀=p
(a>0 and q<0) or (a<0 and q>0) ⇒ two roots
We can also determine the roots (if they exist):
a(x - h)² + k = 0
a(x - h)² = - k
(x - h)² = - k/a
x - h = √[-k/a] ∨ x - h = - √[-k/a]
x = √[-k/a] + h ∨ x = - √[-k/a] + h
Usually you use this form to find the equation of parabola when you have got given the vertex and some other point from that parabola.

Step-by-step explanation:
Answer:
[tex]\frac{2}{15}[/tex] feet
Step-by-step explanation:
Set up a proportion: [tex]\frac{2}{90} = \frac{x}{6}[/tex] Cross multiply, then divide: 2 × 6 = 12, 12 ÷ 90 = [tex]\frac{2}{15}[/tex]I hope this helps!

PLEASE HELP I really need it!!! Steve deposited 2,500$ to the bank. The account has an annual simple interest rate of 4%. After 3 years how much simple interest will Steve Earn? Please Help ASAP
Answer:
$300
Step-by-step explanation:
You want to calculate the interest on $2500 at 4% interest per year after 3 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $2500.00.
r is the interest rate, 4% per year, or in decimal form, 4/100=0.04.
t is the time involved, 3....year(s) time periods.
So, t is 3....year time periods.
To find the simple interest, we multiply 2500 × 0.04 × 3 to get that:
The interest is: $300.00
Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),
or 2500.00 + 300.00 = 2800.00

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

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.
Lines LaTeX: CEC E and LaTeX: ADA D intersect at LaTeX: BB. Lines C E and A D intersect at the point B. Angle A B C is labeled 37 degrees. Select all the true statements. Group of answer choices The measure of angle LaTeX: CBA C B A is equal to the measure of angle LaTeX: DBE D B E . The sum of the measures of angles LaTeX: CBA C B A and LaTeX: DBE D B E is 180 degrees. The measure of angle LaTeX: CBD C B D is equal to the measure of angle LaTeX: ABE A B E . The sum of the measures of angles LaTeX: CBD C B D and LaTeX: CBA C B A is 180 degrees. The sum of the measures of angles LaTeX: CBA C B A and LaTeX: DBE D B E is 90 degrees.
*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.
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.

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.
