What is the equation of the line that passes through the point (-3, 2) and
has a slope of -3?
Answer:
y= -3x -7
Step-by-step explanation:
You can either use y= mx+b or y-y1=m(x-x1)
I will use y= mx+b
y=mx+b
(-3,2) = (x,y) = -3 is x and 2 is y
-3 =m= slope
y=mx+b
2=-3(-3)+b
2= -3 x-3 +b
2= 9+b
you then subtract 9 on both sides because now 9 is positive so you subtract it.
2=9+b
-9 on both sides
-7= b and the final answer is above

what is f(3) if f(x) = –4x + 1?
════════ ∘◦❁◦∘ ════════
Answer = -11════════════════════
Knownf(x) = -4x + 1
════════════════════
Questionf(3) = ..?
════════════════════
Way to do#since the x in (x) changed into (3) this means that the x change into (3)
f(3) = -4(3) + 1
f(3) = -12 + 1
f(3) = -11
════════════════════
Answer:
f(3) = 13
Step-by-step explanation:
4x3=12
f(3)=12+1
12+1=13
help me pls ❤️❤️❤️ ty to the person who decides to help ❤️
Answer:
8/5
Step-by-step explanation:
this is a slope formula which formats y=mx+b
m being the slope
and b being the y-intercept
so no need to look far, and no need to solve anything but 8/5 would be your y-intercept

Show that the statement is true. If ST has endpoints S(-6, -3) and T(0,3), then the midpoint M of ST lies
on the x-axis.
The midpoint M is
D. M lies on the (select), since the y-coordinate is....
Help asap please
Answer:
Use the midpoint formula
Step-by-step explanation:
(-6 + 0 ) ÷ 2 , (-3 + 3) ÷ 2
M = ( -3 , 0) which lies on the x axis
The midpoint M of ST lies on x axis is true
the midpoint M is (-3,0)
M lies on x axis because the y coordinate is 0
Given :
ST has endpoints S(-6, -3) and T(0,3)
Lets find out the midpoint M using midpoint formula
[tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
Here our (x1,y1) is (6,-3) and (x2,y2) is (0,3)
Now apply the midpoint formula to find out midpoint M
[tex](\frac{-6+0}{2}, \frac{-3+3}{2})\\(-3,0)[/tex]
So the midpoint M is (-3,0)
M lies on x axis because the y coordinate is 0

Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -9 -0)/(4 - 7)
= -9/-3

Find the value of x.
Answer:
x = 4
Step-by-step explanation:
ΔABC ≈ ΔDBE
set up a proportion of corresponding sides:
BD / BE = BA / BC
BA = 10 - x + x = 10
10-x / 3 = 10 / 5
cross-multiply:
5(10 - x) = 3(10)
50 - 5x = 30
-5x = -20
x = 4

O A.3
OB. -9
O c.-4
O D.-17
Answer:
B
Step-by-step explanation:
Remark
I have to represent f(x) as plus +f(x)
I like to show this situation as +f(g(x)) which I think is much clearer.
+f(x) = 5x - 4
Solution
+f(g(x)) = 5(g(x)) - 4 What has happened is that wherever you see an x on the right you put in g(x).
Now on the right, you put whatever g(x) is equal to.
+f(g(x)) = 5(x^2 - 1) - 4
Remove the brackets.
+f(g(x)) = 5x^2 - 5 - 4
And make x = 0
+f(g(0)) = 5*0 - 5 - 4
+f(g(0)) = - 9

Phil is making a number cube out of cardboard He traces one face of the number cube onto a coordinate grid The coordinates of two opposite vertices of the face are (4, 8) and (12, 16) What is the surface area, in square units, of Phil's entire number cube?
=============================================================
Explanation:
Let A = (4,8) and B = (12,16)
Form point C at the location (12,8). Note how points A and C are on the same horizontal level, or they have the same y coordinate.
The distance from A(4,8) to C(12,8) is 12-4 = 8 units. Ignore the y coordinates and subtract the x coordinates. This trick only works for horizontal line segments.
So we can see that each square face has a side length of 8 units. The area of each square face is 8^2 = 8*8 = 64 square units.
There are six of these faces, so 6*64 = 384 square units is the total surface area of the number cube.

Answer:
x=3
Step-by-step explanation:
The problem can be re-written as :
[tex] \sqrt{3^{x} } \div \sqrt{3} = 3[/tex]
This is because x to the power of 1/2 is the same as the square of x.
multiply both sides by sqrt3
[tex] \sqrt{3^{x} } = 3 \sqrt{3} [/tex]
square both sides
[tex]3 ^{x} = (3)^{2} ( \sqrt{3} )^{2} [/tex]
simplify
[tex]3 ^{x} = 9 \times 3[/tex]
3 to the power of x is equal to 27
3 cubed (to the power of 3) is 27
so x is equal to 3.
hope i helped, and good luck :)
