What is the x-intercept of the line with this equation
8x-1/3y=16
Answers
9514 1404 393
Answer:
x = 2
Step-by-step explanation:
You find the x-intercept by setting y=0 and solving for x.
8x -1/3(0) = 16
8x = 16
x = 16/8 = 2
The x-intercept is 2.
_____
Additional comment
As you can see, the x-intercept is the ratio of the constant to the x-coefficient. The same is true for the y-intercept. It is 16/(-1/3) = -48.

Gabriel deposits $250 into his savings account when he first opens the account. he then deposits $40 every month after that. how much money will he have after 9 months?
Answers
Answer:
610
Step-by-step explanation:
Multiply the monthly $40 by the 9 months
(40 times 9 = 360)
Then you would need to add in the original $250 deposit money
(360 + 250 = 610)
(Pythagorean theorem) find the missing side length. Round to the nearest hundredth (show steps)
Answers
Answer:
9.09
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
When looking at the triangle we see that we have the hypotenuse and the opposite side.
a = opposite
b = adjacent
c = hypotenuse (always)
So if we plug those numbers into the equation we can get the missing side length
1) a² + b² = c²
2) 9.7² + b² = 13.3²
3) b² = 13.3² - 9.7²
4) b² = 176.89 - 94.09
5) b = [tex]\sqrt{176.89 - 94.09}[/tex]
6) b = 9.093954036
Now we round to nearest hundredth
To find the nearest hundredth we have to look at the thousandth place in the thousandth place we have 3 (9.093) that rounds down so,
b = 9.09

An item is regularly priced at $55 it is now priced at a discount of 65% of the regular price
Answers
Answer:
$19.25
Step-by-step explanation:
Multiply 55 dollars by .65 to get the amount of money that is being dropped. 65% of 55 dollars is 35.75
Now subtract the original amount (55 dollars) by 35.75 dollars to get 19.25 dollars.
An easier way to do this is just by multiplying 55 dollars by the amount or percentage that is left so you multiply 55 by .35 and you will get the same answer.

Enlarge triangle ABC by scale factor -2, centre (4,2)
Answers
Answer:
see attached
Step-by-step explanation:
The scale factor of -2 means each point on the preimage will be reflected across the center of dilation a distance twice its distance to that center.
For example, point B is 2 units right and 1 unit down from the center of dilation. Its image will be 4 units left and 2 units up from the center of dilation, so will have coordinates B'(0,4).
C is 1 unit right of B, so C' will be 2 units left of B', at C'(-2, 4).
A is 4 right and 1 up from the center, so A' will be 8 left and 2 down from the center, at A'(-4, 0).

Answer:
76 quarters, 3 dimes
Step-by-step explanation:
if the whole number is 19, you would have to figure out how many quarters would be in 19$. 76 quarters are in 19$. then you would have to figure out how many dimes are in 30 cents, there are 3 dimes in 230 cents
Answer:
66 Quarters and 28 dimes
Step-by-step explanation:
.10d + .25Q = 19.3Q
d + Q = 94
so d = 94 - Q
Substitution method:
.10(94 - Q) + .25Q = 19.30
9.4 - .10Q + .25Q = 19.30
9.4 + .15Q = 19.30
.15Q = 9.9
Q = 66 so d = 94 - 66 = 28

Joseph compared the graphs of two functions.
The first function was f(x)=−2x+6.
The second function fits the values in the table:
x 2 5 8 11
y 2 -4 -10 -16
What is the distance between the y-intercepts of the two functions? To earn full credit, show your work using a method explained in the Orientation.
Answers
Answer:
There is no separation (distance) between the first y-intercept (6) and the second (6).
Step-by-step explanation:
We'll assume that the table shows points on a straight line.
If we go from x = 2 to x = 8 (an increase of 6), the corresponding y values go from y =2 to y = -10 (a decrease of 12). Thus, the slope of the line represented by the table is
m = rise / run = -12/6, or m = -2.
We need to find the equation of the line represented by the table, so that we can know the y-intercept. Start with y = mx + b and substitute -2 for m:
y = -2x + b. We arbitrarily choose an ordered pair from the table, such as (11, -16). Here we substitute 11 for x and -16 for y:
-16 = -2(11) + b, or
-16 = -22 + b, which yields b = 6.
This is the same y-intercept as the '6' in the given f(x) = -2x + 6. So: There is no separation (distance) between the first y-intercept (6) and the second (6).

So, the slope is -3/5, and the y axis is unidentified.
A point is located at (6,-5). We will use this point.
In order to get the y-axis, we will use 5 from the slope because the denominator allows us to move left and right.
We will also use 6 from the point to give us a dot in the x-coordinate.
We will then divide 5 from the 6 to give us how much we have to go up or down
6/5
We will then use the -3 in the slope.
We will times -3 to the 6/5 in order to know how much we have go up or down.
-18/5 + 5 (from the point)((and since we are moving back, we will add a negative) (My problem))= 1 2/5 (y-intercept)
y = -3/5x + 1 2/5
The y = 13, we will plug it in the equation.
13 = -3/5x + 1 2/5 (subtract 1 2/5 on both sides)
11 3/5 = -3/5x (times 5 on both sides)
-3x = 58 (divide -3 on both sides)
x = -58/3

what is an estimate for the square root of -93

approximately 9.64Step-by-step explanation:
The square root of 93 is approximately 9.64.
Answer:
9.3 or 9.4Step-by-step explanation:
We need to estimate √93.
Use formula below:
[tex]\sqrt{x^2+y} =x +(x/2y)[/tex]or
[tex]\sqrt{x^2-y} =x -(x/2y)[/tex]In the given case the formula works as:
[tex]\sqrt{93} =\sqrt{9^2+12} =9+(9/2*12) = 9+(9/24)=9.4[/tex]or
[tex]\sqrt{93}=\sqrt{10^2-7} =10-(10/2*7)=10 - 5/7 = 9.3[/tex](x-4)^2-(x-4)(x+3)=35
Answers
Answer:
Step-by-step explanation:
(a - b)² = a² - 2ab + b²
(x -4)² - (x - 4)(x +3) = 35
x² - 8x + 16 - [ x(x +3) - 4(X +3)] = 35
x² - 8x + 16 - [x² + 3x - 4x - 12 ] = 35
x² - 8x +16 - [ x² -x - 12] = 35
x² - 8x + 16 -x² + x + 12 = 35
x² - x² - 8x + x + 16 + 12 = 35 {Combine like terms}
-7x + 28 = 35
-7x = 35 -28
-7x = 7
x = 7/-7
x = -1
