g(-1)=3×(-1)²-2×(-1)-5 g(-1)=3×1+2-5 g(-1)=3+2-5 g(-1)=5-5 g(-1)=0 ......
The value of g(x) = 3x² - 2x - 5, at x = -1 is g(-1) and it is equal to zero.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function g(x) = 3x² - 2x - 5.
Now, The value of g(-1) is the same as x = - 1 in g(x).
Therefore, g(-1) = 3(-1)² - 2(-1) - 5.
g(-1) = 3 + 2 - 5.
g(-1) = 0.

An artist sells his drawings for $75 each, and his paintings for $400 each, He
hopes to make at least $2000 monthly. If he sells three paintings in one
month, how many drawings does he need to sell to reach $2000?
- He must sell at least 10 drawings to reach $2000.
-He must sell at least 10.7 drawings to reach $2000.
-He must sell at least 11 drawings to reach $2000.
-He must sell 4,000,000 drawings to reach $2000.
Answer: He must sell at least 11 drawings to reach $2000.
Step-by-step explanation:
The artist sold 3 paintings in one month, the paintings is $400 each so if we were to do 400*3 it would give us 1,200.
Now if we do 11*75 (Each DRAWING costs $75) it would be $825.
$825+1,200= 2,025 will be the closest to 2,000

Answer:
y = 4x + 2
Step-by-step explanation:
This is the formula: [tex]y - y_{1} = m(x - x_{1})[/tex]
y - 2 = 4(x - 0) (distribute the 4)
y - 2 = 4x (add 2 on both sides)

Farmer Jonson is putting together vegetable baskets. He has 270 carrots and 180 beets. What is the largest number of baskets he can put together so that he can have the same number of carrots in each basket and the same number of beets in each basket?
Answer:
90 Baskets is the answer tell me if it was right
Answer:
90 basketsStep-by-step explanation:
To get the answer to this problem you have to find the GCF of 270 and 180
270= 2 x 3 x 3 x 3 x 5
180= 2 x 3 x 3 x 5
So, the GCF equals to 2 x 3 x 3 x 5
2 x 3 x 3 x 5= 90
find equation of straight line which
divides the line joining the points P(-1, -4) and Q (7, 1) in the ratio of 3:2 and perpendicular to it.
Answer:
The required equation is: [tex]y = -\frac{8}{5}x+\frac{127}{25}[/tex]
Step-by-step explanation:
The slope-intercept form of a line is given by:
[tex]y = mx+b[/tex]
For writing equation of a line, slope and a point is needed from which the line passes.
In order to find the slope of line perpendicular to PQ, we have to find slope of PQ first.
Slope is denoted by m and given by the formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Given points are:
P(-1, -4) and Q (7, 1)
Putting the values
[tex]m = \frac{1-(-4)}{7-(-1)}\\m = \frac{1+4}{7+1} = \frac{5}{8}[/tex]
The product of slope of two pependicular lines is -1
Let m1 be the slope of line perpendicular to PQ
[tex]m.m_1 = -1\\\frac{5}{8}.m_1 = -1\\m_1 = \frac{8}{5} * -1\\m_1 = -\frac{8}{5}[/tex]
Now for the point, we have to find the point that divides PQ in ratio 3:2
The formula is:
[tex](x,y) = (\frac{nx_1+mx_2}{m+n} , \frac{ny_1+my_2}{m+n})\\[/tex]
Here
m = 3
n= 2
Putting the values
[tex](x,y) = (\frac{(2)(-1)+(3)(7)}{3+2} , \frac{(2)(-4)+(3)(1)}{3+2})\\= (\frac{-2+21}{5} , \frac{-8+3}{5})\\=(\frac{19}{5} , \frac{-5}{5})\\=(\frac{19}{5} , -1)[/tex]
So we have to write equation of a line with slope -8/5 and passing through point (19/5, -1)
Putting the values in slope-intercept form
[tex]y = -\frac{8}{5}x +b[/tex]
Putting the point in the equation
[tex]-1 = -\frac{8}{5} (\frac{19}{5}) + b\\-1 = -\frac{152}{25} + b\\b = -1+\frac{152}{25}\\b = \frac{-25+152}{25}\\b = \frac{127}{25}[/tex]
Putting the value of b
[tex]y = -\frac{8}{5}x+\frac{127}{25}[/tex]
Hence,
The required equation is: [tex]y = -\frac{8}{5}x+\frac{127}{25}[/tex]

Answer: x ≠ 5; x≠ 0

Reject x = 5.
Answer is x = 1.
Choose all of the equations that have the solution x = - 1/4
x + 1 / 2 = - 1 / 4
x - 1 / 2 = - 3 / 4
x - 1 / 2 = 1 / 4
1 / 2 + x = 1 / 4
x - 1 / 4= - 1 / 2
Answer:
x - 1 / 2 = 1 / 4
x - 1 / 2 = - 3 / 4
Step-by-step explanation:
Answer:
x - 1 / 2 = 1 / 4
x - 1 / 2 = - 3 / 4
the roof of the school has a rise of 3.6 meters and a run of 12 meters. what is the slope/pitch of the roof?
Answer:
The slope will be:
slope = 0.3
Step-by-step explanation:
As we know that the slope of a certain line is basically the measure of its steepness.
Mathematically, the slope can be calculated as 'rise over run'.
In other words, the 'rise' is 'change in y', and 'run' is 'change in x'.
Given
The roof of the school has a rise = 3.6 meters = rise = change in y
The roof of the school has a run = 12 meters = run = change in x
So the slope will be:
slope = rise ÷ run
= 3.6 ÷ 12
= 0.3 ∵( 3.6 ÷ 12 = 0.3)
Therefore, the slope will be:
slope = 0.3
On a coordinate plane, solid circles appear at the following points: (negative 4, 2), (negative 2, 2), (negative 1, 4), (1, 1), (1, 3), (2, negative 3).
Which ordered pair could be removed from the graph to create a set of ordered pairs that represents a function?
A.(–4, 2)
B.(–1, 4)
C.(1, 3)
D.(2, –3)
The correct option is option C i.e., (1,3).
It is given that a circle has the points (4, 2), (-2, 2), (-1, 4), (1, 1), (1, 3), (2, -3).
We have to check which ordered pair from given options is correct.
What do you mean by domain and ranges of a function ?
The domain is set of all values for which the function is defined and the range of the function is set of all values that function takes.
As per the question ;
A circle has the points ;
(4, 2), (-2, 2), (-1, 4), (1, 1), (1, 3), (2, -3).
We know that ;
A function is just like a machine that gives an output for a given unique input. The input given to the function is called the domain whereas the output of a function is called its range.
Also ;
The domain is the independent variable and is represented by the 'x' coordinate and range depends on the values of the domain and is represented by the 'y' coordinate.
Now ; check for relation.
Here ; the ordered pairs (1, 1) and (1, 3) have the same input. So if we remove either of them , it will make the relation as a function.
So;
The correct option is C.
Thus , the correct option is option C i.e., (1,3).
