Answer:
-1
Step-by-step explanation:
F(x - 1) = 2x + 3.
Rewrite the right side (2x + 3)
F(x - 1) = 2[ x ] + 3
F(x - 1) = 2[ x - 1 + 1 ] + 3 = 2 [ (x - 1) + 1 ] + 3
= 2 (x - 1) + 2 + 3
= 2(x - 1) + 5
replace "x - 1" with "-3" :
F(-3) = 2(-3) + 5 = -1
A builder of tract homes reduced the price of a model by 15%. If the new price is $255,000, what was it's original price? How much can be saved by purchasing the model?
Answer:
Original=$300000
Saved=$45000
Step-by-step explanation:
100%/15%=85%
85%=255000
1%=255000÷85=3000
100%=3000x100=300000
300000-255000=45000

Given: ΔABC, CM⊥AB, BC = 5, AB = 7, CA = 4√2
Find: CM
Step-by-step explanation:
first finding the area of the triangle by Heron's formula.
s=(a+b+c)/2, a=BC=5 unit, b=AC= 4√2unit, c=AB=7unit.
s=(5+4√2+7)/2 = (12+4√2)/2 =2( 6+2√2 )/2 = 6+2√2 unit .
Now, the Heron's formula : √s(s-a)(s-b)(s-c)
> √ (6+2√2)[(6+2√2)-5][(6+2√2)-4√2][(6+2√2)-7]
we have use √2's value ; 1.414 to simplify.
please simplify it with the help of calculator or doin it in a copy, because it is very difficult to share the full calculation. AFTER CALCULATION,
> √196.0000 > 14(units)².
Now, we know that the area of triangle is 14(units)². and another formula of finding the area of triangle is ½(base)(height). let the height be h.
Area = ½(base)(height)
=>14= ½(7)h. (after cross multiplication)
=>(14×2)/7=h. (after cancellation)
=>2×2=h.
=> 4units = h.
Therefore, CM that is the height is 4units.
I have every time written units because the unit is not given or you have not posted if given in the question you will write that unit only like cm or m anything like that.
For the function, find the point(s) on the graph at which the tangent line has slope 2.
y=-0.025x^2 +4x
If y = -0.025x^2 + 4x, then
y' = -0.05x + 4
Set y' = 2:
2 = -0.05x + 4
-2 = -0.05x
40 = x
Go back to y to find the point:
y = -0.025(40)^2 + 4(40) = 120
So the point (40, 120) on y = -0.025x^2 + 4x will have tangent line with a slope of 2.

Write an English phrase as an algebraic expression for the sum of 14 and a number, divided by 5.
Answer:
X/5 = 14
Step-by-step explanation:
We know that the sum will be what the answer of the algebraic equation. We know that the unknown number will be divided by 5. We should mark the unknown number with a variable. I personally used X. So we should write X divided by 5 equals 14.

Step-by-step explanation:
-1/2 (7z + 4) + 1/5 (5z - 16)
-1/10 × (5(7z + 4) - 2 (5z - 16))
-1/10 × (35z + 20 - 10z + 32)

Determine the point and slope from the equation: y - 4 = -5(x + 2) *
a) point: (2, -4) slope: -5
b) point: (4, -2) slope: -5
c) point: (-2, 4) slope: -5
d) point: (-4, 2) slope: -5
c) point: (-2, 4) slope: -5
Answer:
c) point: (-2, 4) slope: -5
Step-by-step explanation:
1. The point-slope form of a linear equation is written as: [tex]y-y_1=m(x-x_1)[/tex], where [tex]y_1=[/tex] y-coordinate of point one, m = slope, and [tex]x_1=[/tex] x-coordinate of point one.
2. The x-coordinate should be -2, and the y-coordinate should 4. That makes the point (-2,4). M, the slope, is -5.

In 13 liters of 18% salty solution we add 402g of salt. What is the concentration of the new mixture?
9514 1404 393
Answer:
21.1%
Step-by-step explanation:
Adding 402 g of salt to a solution whose volume is 130 × 100 mL will increase the concentration by (402/130)%, or about 3.09%.
When the concentration of 18% has 3.09% added to it, the concentration of the new mixture is about 21.1%.
_____
Additional comment
We understand the units of concentration used here to be (1 g)/(100 mL) = 1%. These units are often used for a solution with a dissolved solid.

Which of the following tables could represent a linear function? For each that could be linear, find a linear equation models the data.

Answer:
y -6 = (-25/2)xy -13 = 5(x -2)y +4 = 10(x -2)not a linear relationStep-by-step explanation:
The function will be linear if the differences in y-values are proportional to the differences in x-values. The constant of that proportionality is the slope of the line. A linear equation can be written using the point-slope form:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
__
Table 1
x-differences: 2-0 = 2, 4-2 = 2, 6-4 = 2
y-differences: -19-6 = -25, -44-(-19) = -25, -69-(-44) = -25
m = -25/2; (h, k) = (0, 6)
linear relation: y -6 = (-25/2)x
__
Table 2
x-differences: 2, 4, 2
y-differences: 10, 20, 10
m = 10/2 = 20/4 = 10/2 = 5; (h, k) = (2, 13)
linear relation: y -13 = 5(x -2)
__
Table 3
x-differences: 2, 2, 2
y-differences: 20, 20, 20
m = 20/2 = 10; (h, k) = (2, -4)
