Write an equation for the line shown on the graph.
y =3/2 x - 2
y = 2/3x + 1
y = 2/3x - 2
y =3/2 x + 1
Answers
Answer: y = 2/3x +1 (the second option)
Step-by-step explanation:
Equation: y = mx + bm (slope) = 2/3 --> rise over runb (y intercept) = 1The required equation will be y = -0.5x + 27.5 which is shown on the given graph.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
According to the given graph,
We can see two points are (-3, -1) and (3, 3)
The linear equation will be: y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
Here
x₁ = -3, y₁ = -1
x₂ = 3, y₂ = 3
⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]
Substitute values in the equation, we get
⇒ y - (-1) = (3 - (-1))/(3-(-3))(x-(-3))
⇒ y + 1 = (4)/(6)(x + 3)
⇒ y + 1 = 2/3(x + 3)
⇒ y = (2/3)x + 2 + 1
⇒ y = (2/3)x + 3
⇒ 3y = 2x + 9
Thus, the required equation will be 3y = 2x + 9.

A compound is made up of various elements totaling 90 ounces. If the total amount of uranium in the compound weighs 18 ounces, what percent of the compound is made up of uranium? If necessary, round your answer to the nearest hundredth.
Answers
Answer:
20%
Step-by-step explanation:
The percent of the compound that is made of uranium is calculated as:
(Number of ounces of uranium /Number of ounces of the compound)
× 100
Total amount of uranium in the compound weighs = 18 ounces
A compound is made up of various elements totaling = 90 ounces.
Hence:
= 18/90 × 100
= 1800/90
= 20%
Therefore, the percent of the compound that is made up of uranium is 20%

Step-by-step explanation:
The product 55 x 25 equaled to 1375
What is Multiplication?Multiplication is a method of finding the product of two or more numbers
55 x 25 is equal to 1,375.
To calculate this product, we can multiply the units digit (5) of the two numbers and write it as the units digit of the result.
Then, we multiply the tens digit (5) of 55 by 25 and add any carry-over from the previous step (0) to get the tens digit of the result.

what is the slope intercept form x+y=-15
Answers
Answer:
y=-x-15
Step-by-step explanation:
used mathaway calculator!! probably would be useful if youre doing more question like shown. :) mark brainlest pls
To find the slope intercept form, you need to isolate y.
We need to get x on the other side of the equation.
You can do this by subtracting x from each side of the equation.
x+y-x = y
-15-x = -15-x
You get...
y = -15-x
Now you need to get the x before the -15.
So just switch them.
y = -x-15
And your done.

Given:
In a right angle triangle,
Perpendicular = 8 units
Base = x units
Hypotenuse = 17 units
To find:
The exact value of x.
Solution:
The given triangles is a right angle triangle. So, side lengths form a Pythagorean triplet.
[tex](Hypotenuse)^2=(Base)^2+(Perpendicular)^2[/tex]
[tex](17)^2=(x)^2+(8)^2[/tex]
[tex]289=x^2+64[/tex]
[tex]289-64=x^2[/tex]
[tex]225=x^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{225}=x[/tex]
[tex]\pm 15=x[/tex]
Side cannot be negative. So, [tex]x=15[/tex].
Therefore, the required value is [tex]x=15[/tex] and yes, the side lengths form a Pythagorean triplet, i.e., (8,15,17).

Suppose that Omar's marginal utility for cups of coffee is constant at 1.5 utils per cup no matter how many cups he drinks. On the other hand, his marginal utility per doughnut is 10 for the first doughnut he eats, 9 for the second doughnut he eats, 8 for the third he eats, and so on (that is declining 1 unit for each additional doughnut consumed). Suppose that coffee costs $1.00 per cup and doughnuts $1.00 each, and Omar has a budget that he can spend only on doughnuts and coffee. How large would his budget need to be before he would spend a dollar on coffee?
Answers
Answer:
$6.5
Step-by-step explanation:
The marginal utility per dollar of a commodity is obtained by:
Marginal utility of coffee = 5.5
Price of coffee = $1
The marginal utility of doughnut declines by 1 per additional unit of donut consumed :
10 / 1, 9 /1..... 1/1
Therefore , before a dollar can be spent on coffee, then the marginal. Utility of coffee should be greater than doughnut.
5.5 doughnuts will be purchased, at this time marginal utility of doughnut will be 5.5/1, the 6th doughnut will have a marginal utility of 5 which is less than that of coffee.
Cost of 5.5 donuts = $5.5
Cost of coffee = $1
Total = $(5.5 + 1) = $6.5

a=4 b=-14 c=10
firat find discriminant with formula:
D=b^2-4ac(-14)^2-(4×4×10)=196-160=36
now find x1 and x2 with formula:
X=(-b±√D)/2a
x1=(14+√36)/8=20/8=2.5
x2=(14-√36)/8=8/8=1
lets put values :
if we put x2 value as a base, which is 1 in given height and base, we will get 2(1)-2=0. measure of amy side can't be 0.
and if we put x2 in height, it will give us zero.
so no matter which one we put as value. we will get 0cm^2. so i think it cant be detected. im sorry if im wrong
Use the discriminant to determine the number and type of solutions for the equation 2x^2−4x+7=0
(A). The equation has 2 real solutions because the discriminant is positive.
(B). The equation has 1 real solution and 1 imaginary solution because the discriminant is negative.
(C). The equation has 2 imaginary solutions because the discriminant is negative.
(D). The equation has 1 real solution because the discriminant is 0.
