A line with a slope of 5 passes through the point (1,8). What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
y = x +
X
Answer:
Step-by-step explanation:
In point-slope form, our equation would be y - 9 = 2(x - 1). Expanding, we get y - 9 = 2x - 2. Solving for y, we obtain the form of the equation as shown in the problem: y = 2x + 7.
So, the numbers that would go in the blanks would be 2 and 7, respectively.

Answer:
n = −0.7, so the second one is the answer
Step-by-step explanation:
−2n + 1.8 = 3.2
Step 1: Subtract 1.8 from both sides.
−2n + 1.8 − 1.8 = 3.2 − 1.8
−2n = 1.4
Step 2: Divide both sides by -2.
-2/-2 = 1.4/-2
n = −0.7

Is x=4 a solution to the equation 9x = 32 + x?
Answer:
yes
Step-by-step explanation:
because 9*4=36 and well it's 36=32*? so 36-32 is 4
So well the solution is x=4
Answer:
Yes, it is.
Explanation:
For x = 4 to be a solution of the given eqⁿ, it must satisfy it. That is,
9x = 32 + x => 8x - 32 = 0
=> f(x) = 8x - 32
At x = 4,
f(4) = 8(4) - 32 = 32 - 32 = 0
Since, f(4) = 0, thus, x = 4 is a solution to the given eqⁿ.

Answer:
89.1
Step-by-step explanation:
14/43 = 29/x, 14x = 1247, x = 89.1
Answer:
NK≈89.1
Step-by-step explanation:
We know the smaller figure to the bigger figure is 14:43 because of side GH and KL.
So, to find NK, we write:
29:NK=14:43
Then, we make it into a fraction,
29/NK=14/43
And now cross multiply
29·43=14×NK
1247=14NK
NK≈89.1

Keanu bought a new laptop computer and paid a
discount price that was 20% less than the $1,000 list
price. He also paid tax on the laptop equal to 6% of the
discount price. What is the total amount Keanu paid
for the laptop computer?
Answer:
$848
20% of 1000 = 200
1000 - 200 = 800
6% of 800 = 48
800 + 48 = 848

The range of f(x) = |x| is y > 0.
If a < 0 for g(x) = a|x|, what is the range of the function of g?
A. Y < a
B. Y < 0
C. Y > 0
Step-by-step explanation:
first of all I have to say the range should be " y >= 0" and not just "y > 0", because x can be 0, and then y is 0 too.
but under the the same assumption of the definition above, the correct answer is B, y < 0.
because a×|x| means we multiply a negative value with a positive value. and that result is always a negative value.
so, it cannot be C.
and it cannot be A, because
if |x| < 1 (e.g. 0.5), then a×|x| > a, as e.g. -1 > -2
Find the zeros of the function f(x)=x^2-2x-2.f(x)=x2−2x−2. Round values to the nearest hundredth (if necessary).
By definition, the zeros of the quadratic function f(x) = x² - 2x - 2 are 2.732 and -0.732.
Zeros of a functionThe points where a polynomial function crosses the axis of the independent term (x) represent the so-called zeros of the function.
That is, the zeros represent the roots of the polynomial equation that is obtained by making f(x)=0.
In summary, the roots or zeros of the quadratic function are those values of x for which the expression is equal to 0. Graphically, the roots correspond to the abscissa of the points where the parabola intersects the x-axis.
In a quadratic function that has the form:
f(x)= ax² + bx + c
the zeros or roots are calculated by:
[tex]x1,x2=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]
This caseThe quadratic function is f(x) = x² - 2x - 2
Being:
a= 1b= -2c= -2the zeros or roots are calculated as:
[tex]x1=\frac{-(-2)+\sqrt{(-2)^{2} -4x1x(-2)} }{2x1}[/tex]
[tex]x1=\frac{2+\sqrt{4 +8} }{2}[/tex]
[tex]x1=\frac{2+\sqrt{12} }{2}[/tex]
[tex]x1=\frac{2+3.464}{2}[/tex]
[tex]x1=\frac{5.464}{2}[/tex]
x1= 2.732
and
[tex]x2=\frac{-(-2)-\sqrt{(-2)^{2} -4x1x(-2)} }{2x1}[/tex]
[tex]x2=\frac{2-\sqrt{4 +8} }{2}[/tex]
[tex]x2=\frac{2-\sqrt{12} }{2}[/tex]
[tex]x2=\frac{2-3.464 }{2}[/tex]
[tex]x2=\frac{-1.462 }{2}[/tex]
x2= -0.732
Finally, the zeros of the quadratic function f(x) = x² - 2x - 2 are 2.732 and -0.732.

What is the vertex form of function?The vertex of a parabola is the point at which the parabola passes through its axis of symmetry.
The standard equation which represents the vertex form of the function is;
[tex]\rm f(x) =(x-h)^2+k^2[/tex]
Where h and k are vertexes of the given parabola.
The function is in vertex form;
[tex]\rm f(x)= 7 x^2 + 42 x\\\\ f(x) = 7 ( x^2+ 6 x ) \\\\ f(x)= 7 ( ( x^2+ 6 x + 9 ) - 9 ) \\\\ f(x)= 7 ( x + 3 )^2 - 63[/tex]
Hence, the vertex form of the function f(x) is [tex]\rm f(x)= 7 ( x + 3 )^2 - 63[/tex].

At a carnival, Jack and his brother collected 53 pieces of candy all together. Each of them
ate 5 pieces of candy that evening. The next day, Jack had 19 pieces left. How many pieces
did Jack's brother have left?
The number of candies Jack's brother has left if Jack and his brother collected 53 pieces of candy altogether. Each of them ate 5 pieces of candy that evening. The next day, Jack had 19 pieces left is 24.
What is subtraction?The process of finding the difference by subtracting a matrix, vector, or another variable from another in accordance with preset principles.
Given:
The total no of candies = 53,
The no of candy eaten = 5 pieces each,
The no of candies Jack had = 19,
Now, The no of candies Jack's brother have left = The total no of candies - The no of candy eaten + The no of candies Jack had
Substitute the values,
The no of candies Jack's brother have left = 53 - 5 × 2 + 19 = 24,
Therefore, the number of candies Jack's brother has left if Jack and his brother collected 53 pieces of candy altogether. Each of them ate 5 pieces of candy that evening. The next day, Jack had 19 pieces left is 24.
