All lines parallel to y=2x-3 will have the same slope as y=2x-3. So how do you find the slope of y=2x-3? Very simple! When written in slope-intercept form you simply look at the coefficient of the ‘x’ term. In this instance the coefficient is 2. Therefore any equation that has a slope of 2 will be parallel to y=2x-3. In general we can say that the family of equations parallel to y=2x-3 is y=2x+b where b is the y-intercept.
Fill in the table using this function rule. y=6x + 5
Answer:
11, 17, 29, 65
Step-by-step explanation:
Rrplace x with values on the x colon
Answer:
Column 1 (When x = 1): y = 11
Colum 2(When x = 2): y = 17
Column 3(When x = 4): y = 29
Colum 4(When x= 10): y = 65
Step-by-step explanation:
When x = 1; y = 6(1) + 5
=> y = 6 + 5
=> y = 11
When x = 2; y = 6(2) + 5
=> y = 12 + 5
=> y = 17
When x = 4; y = 6(4) + 5
=> y = 24 + 5
=> y = 29
When x = 10; y = 6(10) + 5
=> y = 60 + 5
=> y = 65

Write an exponential function in the form y=ab^x that goes through points (0,12) and (3,6144)
Given:
An exponential function goes through points (0,12) and (3,6144).
To find:
The exponential function.
Solution:
The general exponential function is:
[tex]y=ab^x[/tex] ...(i)
The function goes through point (0,12). Substituting [tex]x=0,y=12[/tex], we get
[tex]12=ab^0[/tex]
[tex]12=a[/tex]
The function goes through point (3,6144). Substituting [tex]a=12, x=3,y=6144[/tex] in the general exponential function, we get
[tex]6144=12b^3[/tex]
[tex]\dfrac{6144}{12}=b^3[/tex]
[tex]512=b^3[/tex]
[tex]512^{\frac{1}{3}}=b[/tex]
[tex]8=b[/tex]
Putting [tex]a=12,b=8[/tex] in (i), we get
[tex]y=12(8)^x[/tex]
Therefore, the required exponential function is [tex]y=12(8)^x[/tex].

Angles equation for geometry.
Answer:
40 degrees
Step-by-step explanation:
Since we have the diameter included in the triangle, the angle at B is 90
This is because angle at center is two times the angle at the circumference
Since we have the diameter, the angle at the center will be 180 degrees so the angle A at the circumference will be 90 degrees
Now, let us use the measure of the arc given
The angle at C is half of 100 which makes it 50
This is according to an angle arc relationship
Lastly, the sum of angles in a triangle is 180 degrees
We already have two angles and we need the last
so we have to add what we have already and subtract from 180 to get the angle we are looking for
So we have the angle as 180-(90 + 50) = 180 -140 = 40

There are 8 blue marbles, 3 red marbles, and 4 yellow marbles in a bag. What is the probability of selecting a purple marble on the first draw?
Answer:
0
Step-by-step explanation:
there is only blue marbles, yellow marbles, and red marbles. there are no purple marbles so you’d be unable to pull out a purple one no matter how many times you tried. so the probability would be 0
What is the focus of the parabola?
y =1/4x^2 -x-1
Enter your answer in the boxes.
Answer:(-y/(1/2)) -x/(1/2)=1
Step-by-step explanation:
The coordinates of the focus of the parabola are (2, -1.9375)
How to determine the focus?The equation of the parabola is given as:
[tex]y = \frac 14x^2 - x - 1[/tex]
Express as a vertex form
[tex]y = \frac 14(x - 2)^2 - 2[/tex]
The focus of a quadratic function of the form [tex]y = a(x - h)^2 + k[/tex] is
Focus = (h, k + 1/4 a)
By comparing [tex]y = a(x - h)^2 + k[/tex] and [tex]y = \frac 14(x - 2)^2 - 2[/tex], we have:
a = 1/4
h = 2
k = -2
So, we have:
Focus = (2, -2 + 1/4 * 1/4)
Evaluate
Focus = (2, -1.9375)
Hence, the coordinates of the focus of the parabola are (2, -1.9375)

im not sure brainliest please ok
Answer:
The answer is C at 8.1.
Step-by-step explanation:
To find [tex]\sqrt{66}[/tex], start by finding the two consecutive perfect squares that 66 lies between them. The two perfect squares are 64 ([tex]8^{2}[/tex]) and 81 ([tex]9^{2}[/tex]). So, the whole number part of the square root of 66 will be 8.
Now, for the decimal part, use the following formula:
(Given number - Smaller perfect square) / (Greater perfect square - Smaller perfect square)
Then, put in the known information, which will look like:
(66 - 64)/(81 - 64) = 2/17 = 0.117
Finally, [tex]\sqrt{66}[/tex] is 8.117, so the answer is C at 8.1.

A jar contains 2 orange, 4 green, 2 white and 2 black balls. What is the probability of drawing an orange ball without putting it back, then drawing a black ball? (write your answer as a simplified fraction)
Answer:
2/45
Step-by-step explanation:
We are told that:
A jar contains 2 orange, 4 green, 2 white and 2 black balls.
The total number of balls in the jar is calculated as:
2 orange balls + 4 green balls + 2 white balls + 2 black balls = 10 balls
The probability of drawing an orange ball = P(Orange) = 2/10
The probability of drawing a black ball = P(Black) = 2/10
Therefore, the probability of drawing an orange ball without putting it back, then drawing a black ball is calculated as:
2/10 × 2/9 = 4/90
= 2/45

Find the coordinates of the minimum point of the function- f(x) = x^2 + 4x - 5.
Solution-
We need to express x^2 + 4 - 5 in the form (x+h)^2 + k.
Let x^2 - 4x = (x - 2)^2 - 4 (Where did the -4 come from?)
x^2 + 4x - 5 = [ (x - 2)^2 - 4] - 5
= (x - 2)^2 - 9
All I wanna know is where the -4 came from. what rule must be applied.
Answer:
Step-by-step explanation:
Using brackets will really help.
y = (x^2 + 4x + ... ) - 5 You are trying to complete the square. The square in this case is a trinomial that is squared.
To do that, you take 1/2 the linear term (4x)/2, drop the x (4/2), and square the result (4/2)^2. The number is 2^2 which is 4.
So far what you have is
y = (x^2 + 4x + 4) - 5
Now you just can't add 4 without adjusting it somehow. If you do, the whole question will change it's value. Because you added 4 inside the brackets, you must subtract 4 outside the brackets.
What that means is 4 inside - 4 outside. So it looks like this
y = (x^2 + 4x + 4) - 5 - 4
Now you continue on
y = (x + 2)^2 - 9 The 4 combines with the 5 to make nine.

An explicit formula to represent the geometric sequence with a first term of 10 and a common ratio of 3.
Answer:
an = 10(3^n-1)
Step-by-step explanation:
The explicit formula of a geometric sequence is written as:
an = ar^n - 1
Where
an = nth term
a = First term
r = common ratio
n = number of terms
Hence, an explicit formula to represent the geometric sequence with a first term of 10 and a common ratio of 3 is written as:
an = 10 × 3^n-1
an = 10(3^n-1)

A spherical boulder is 12 ft in diameter and weighs almost 8 tons. Find the volume. Use 3.14 for pi.
Answer:
904.32 ft^3
Step-by-step explanation:
Volume of a sphere = 4/3 x pi x r^3
r = 12/2 = 6
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
4/3 x 3.14 x 6^3 = 904.32 ft^3
Help please?!?!??!?!!!?!?!?!?!?!?!?!!?!?!?
Answer:
16.7%
Step-by-step explanation:
Probability is defined by the formula: the number of desirable outcomes over the total outcomes. The total number of outcomes is the sum of all shoes that he could possibly pick:
5 + 7 + 1 + 4 + 6 + 8 + 2 + 3 = 36
And the desirable outcomes are those where he picks brown boots, which is 6 outcomes.
Using the formula for probability, we get the expression: 6/36 to represent the probability. It simplifies to 1/6 which is about 16.7%
