The value of the function for x = -1 is 19.
Given is a function f(x) = 3x² + 16 we need to find f(-1),
To find f(-1), we substitute -1 into the function f(x) and evaluate the expression.
Let's do that:
f(x) = 3x² + 16
Substituting x = -1:
f(-1) = 3(-1)² + 16
Simplifying:
f(-1) = 3(1) + 16
f(-1) = 3 + 16
f(-1) = 19
Therefore, f(-1) is equal to 19.

Write the slope-intercept form of the equation of each line
Work out the size of angle x
Answer:
Let's name the angle right close to 51 as c.
c = 180°-51° since angles on a straight line is equal to 180°.
so c= 129°
so x = 129° since it corresponds to c
Answer:
Step-by-step explanation:
Notice that the line that the variable x is on is equal to 180 degrees. Because the angle that it is next to is equal to 51 degrees, you subtract 180 from 51:
180-51=129
The final answer to this problem is 129 degrees.

Which statement correctly explains whether or not the values in the table represent a function of x
Answer:
Step-by-step explanation:
A relation is said to be a function when each input value (x-value) show a distinct output value (y-value).
From the table attached,
For input value x = 0, there are multiple values of output values (y = -2, -1, 0, 1, -2).
Therefore, data given in the table doesn't represent a function.

The graph is a straight line graph. A straight line graph is used to represent a linear equation. A linear equation is represented by the equation: y = mx + c, where y is the dependent variable, x is the independent variable, m is the slope (rate of change) and c is the intercept.
A line passing through the point [tex](x_1,y_1)\ and\ (x_2,y_2)\[/tex] can be represented by the equation:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
Let y represent the distance in miles and x represent the time in hours. From the graph, the line pass through (0.5, 100) and (3.5, 700). Hence using:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-100=\frac{700-100}{3.5-0.5} (x-0.5)\\\\y-100=200(x-0.5)\\\\y-100=200x-100\\\\y=200x-100+100\\\\y=200x\\\\To\ travel\ 480 \ miles,we\ substitute\ y=480\ and\ find\ x\\\\480=200x\\\\x=480/200\\\\x=2.4\ hours[/tex]

y=f(1/3x) & find new coordinates
Answer:
A(-3,0)
B(6,1)
C(15,0)
Step-by-step explanation:
To find the three new coordinates A,B,C we have to find out the equation of the original curve y=f(x) which is shown in the figure. We find that equation by using the turning point (2,1) which is point B and take any other point either A or C which intercept's the x-axis, i took C. We put both these points into the completing square formula of the curve.
[tex]y=a(x-h)^2+k[/tex]
where (h,k) are the turning points (2,1) respectively and C (5,0) corresponds to (x,y)
so the equations becomes
[tex]0=a(5-2)^2+1\\0=a(3)^2+1\\0=9a+1\\-1=9a\\a=\frac{-1}{9}[/tex]
So our equation y=f(x) becomes
[tex]y=-\frac{(x-2)^2}{9}+1[/tex]
now for
[tex]y=f(\frac{x}{3} )[/tex]
we replace the x in the original equation above with x/3 which changes the equation to
[tex]f(\frac{x}{3} )=-\frac{(\frac{x}{3}-2)^2}{9} +1[/tex]
and now we sketch the curve we have our hints for the new points A,B,C our hint is that the original points A and C are the x-intercepts so the new A and C lets name them A' and C' must be the x-intercepts as well and B is the turning point of y=f(x) so the new point B' must be the turning point of y=f(x/3)
so we simply sketch the curve y=f(x/3) use an online graph plotter if you know how to sketch it to save time or if you don't know you can ask me and i'll teach you cause learning to sketch isn't in the question so furthermore we sketch the curve i attached the figure in an image you check it out and the new points as well.

How many solutions exist for the given equation?
3x + 13 = 3(x + 6) + 1
zero
one
two
infinitely many
Answer:
Zero Solutions
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x+13=3(x+6)+1
3x+13=(3)(x)+(3)(6)+1(Distribute)
3x+13=3x+18+1
3x+13=(3x)+(18+1)(Combine Like Terms)
3x+13=3x+19
3x+13=3x+19
Step 2: Subtract 3x from both sides.
3x+13−3x=3x+19−3x
13=19
Step 3: Subtract 13 from both sides.
13−13=19−13

If f(x) = 8x + 1 and the graph of g is the graph f translated 2 units to right, which equation represents g?
A. g(x) = (6x + 1) + 2
B. g(x) = (6x + 1) - 2
C. g(x) = 8(x + 2) + 1
D. g(x) = 8(x - 2) + 1
Can someone please help?
The equation of the graph after 2 units of the right translation will be g(x) = 8(x - 2) + 1. The correct option is d.
What is a function?The expression that established the relationship between the dependent variable and independent variable is referred to as a function. In the function as the value of the independent variable varies the value of the dependent variable also varies.
Given function f(x) = 8x + 1 is translated by 2 units to the right on the graph.
The function will be changed as below,
f(x) = 8x + 1
After translation, the value of x will become x - 2.
f(x) = 8(x-2) + 1
Therefore, the equation of the graph after 2 units of the right translation will be g(x) = 8(x - 2) + 1. The correct option is d.

the original numbers are 5,890,000 and 0.0000521 you have to place the decimal point so that there is only one number between 1 and 9 before the decimal so for the first equation that would end up being 5.89, and to get there you have to move the decimal point 6 places to the right, so the exponent on the 10 would be 6, and the second equation would be 5.21 and for this one you have to move the decimal point 5 units to the left so it would end up being -5/.
