Write an equation of the line with a slope of 2 and y-intercept of −8.
3
Answer:
y = 2x - 8
Step-by-step explanation:
You can use the formula y = mx + b
m = slope
b = y intercept
Therefore,
y = 2x - 8
find the vertex y= 4x*2 -16x+10
Answer:
I hope it helps U
Step-by-step explanation:
As given quadratic equation is ,
y= 4x*2 -16x+10
As general quadratic equation is,
y=ax^2+bx+c , we get a=4 , b=-16 , c=10
as a=4 and +ive so the parabola is up-down facing
vertex formula is X(vertex)= -b/2a putt values in this formula we will get x -coordinate of vertex,
X(vertex)= -(-16)/2*4
X(vertex)= 2
Now to find the Y- Co-ordinate just plug in the value of X in the given equation, hence
Y(vertex)=4(2)^2-16*2+10
Y(vertex)=-6
hence the vertex of given equation is (2,-6)

Simplify the expression. a^-5 b-4/a^-13 b^8
Answer:
a^8 ÷ b^12
Step-by-step explanation:
a^-5 · b^-4 / a^-13 · b^8
when dividing exponents with the same bases, subtract the exponents
a^8 · b^-12
do not leave a negative exponent; put it into the denominator and it becomes positive
b^-12 = 1 /b^12

Step-by-step explanation:
Answer:
19.2
Step-by-step explanation:
Hi there!
First, multiply both sides by 8 to isolate a.
Now, we just multiply [tex]\frac{8}{1}[/tex] and [tex]\frac{36}{15}[/tex].
When we do this, we get 288/15, or 19.2

write an equation in a slope y-intercept form (y=mx+b) slope: -3 y-intercept: 7
Answer:
y=-3x+7
Step-by-step explanation:
Think of it like this, in y=mx+b, the m is representative for the slope and the b is representative of the y-intercept. In this case, the slope is -3, so you substitue the -3 with the m while the y-intercept is 7, so you replace the b with the 7.

Answer the Following Question with Explanation
Answer:
The answer's D.
Step-by-step explanation:
If 40 questions were put in and only 50% of them were used then only 20 questions were used. If you need 40 more questions and 80% of the qustions were used, then she wrote 50 questions.
========================================================
Explanation:
There are 60 questions total.
Amita made 40 questions, but only 50% were considered "good" to be used. So that means 0.50*40 = 20 questions were used.
This means 60-20 = 40 questions remain, and this must be the amount of "good" questions that Meena provided.
We're told that 80% of Meena's questions were considered "good". Let x be the total number of questions she provided.
80% of x = (number of "good" questions Meena offered)
0.80x = 40
x = 40/0.80
x = 50
Therefore, Meena wrote up 50 questions.
The equation x + 8 = 12 represents the number of balloons Dylan needs to decorate a place for a party. Which number line shows how many more balloons Dylan needs?
Answer:
4 balloons
Step-by-step explanation:
According to the problem, the data given are as follows,
Equation given = x + 8 = 12
Here X is showing the number of balloons which Dylan more needs to decorate.
So, by solving the equation, we get
X + 8 = 12
( by taking 8 to RHS )
X = 12 - 8
X = 4
Hence, Dylan need 4 more balloons to decorate for a party.
A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?
Answer:
523.3 cubic inches
Step-by-step explanation:
A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?
The shape of a basketball is spherical.
Hence:
The volume of a basketball = 4/3 × π × r³
From the question,
π = 3.14
r = radius = Diameter/2
r = 10 in/2 = 5 in
Hence:
The volume of the basketball
= 4/3 × 3.14 × 5³
= 1570 ÷ 3
= 523.33333333 cubic inches
Therefore, the approximate volume of the basketball = 523.3 cubic inches

What is 8= 2 + 2u because I don’t know it
Answer:
u = 3
Step-by-step explanation:
Subtract 2 on both sides.
8 - 2 = 2u
Add like terms.
6 = 2u
Divide by 2 on both sides.
u = 3

Lola's age is 14 more than 6 times Juan's age. The sum of their ages is 35. How old is each?
35 - 14 = 21
3 * 6 = 18
3.5 * 6 = 21
Thus Juan is around the age of 3.5 and Lola is 31.5 I believe
Im not quite sure however I think this is the answer, I hope it helps ^-^
