Answer:
y=-2x+2
Step-by-step explanation:
We use the formula
y=mx+b, where m is the slope, b is the y intercept, and x&y are the coordinates.
We know that one point is (-1, 4)
and the slope is -2.
We are trying to find b.
In order to do that, we plug in what we know:
so,
4=-2(-1)+b
4=2+b
4-2=b
b=2
So now we go back to the original equation and use b as our value'
y=-2x+2
Does (4, 0) make the equation y = 6x true?
Answer: No

Find the percent decrease. Round to the nearest percent.
From 85°F to 60°F
Answer:
Percent Decrease ≈ 30%
Step-by-step explanation:
Let's first find what part of 85 is 60
60/85 = 12/17
12/17 = 0.70588 ≈ 0.70 = 70%
Now, since 85 is 100%, and 60 is 70% of 85, the percent decrease is :
100% - 70% = 30%

What is the slope of a line passing through two points?The slope of a line passing through points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] is
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Given two points are [tex]A(-1, -4)[/tex] and [tex]B(2, 5)[/tex].
Therefore, the slope of a line passing through those two points is
[tex]m_{1} = \frac{5 - (-4)}{2-(-1)}[/tex]
⇒ [tex]m_{1} = \frac{9}{3}[/tex]
⇒ [tex]m_{1} = 3[/tex]
Another two points are [tex]C(3, -7)[/tex] and [tex]D(5, -1)[/tex].
[tex]m_{2} = \frac{-1 - (-7)}{5-3}[/tex]

The interest with the given principal, time period and rate of interest is $3076.
Given that, principal=$50,000, time period =6 years and rate of interest =1%.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest is
Amount =Principal(1+r/100)^t
= 50000(1+1/100)^6
= 50000(1.01)^6
= 53076
So, interest =Amount-Principal
= $3076
Therefore, the interest with the given principal, time period and rate of interest is $3076.

Thoughtfully split the expression at hand into groups, each group having two terms :

Pull out from each group separately :
Group 1: (2x - 1) • (1)

Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 1 and the Trailing Constant is -1.
The factor(s) are:
of the Leading Coefficient : 1
of the Trailing Constant : 1
Let us test ....
P Q P/Q F(P/Q) Divisor

The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

If the number was OUTSIDE the exponents it represents a movement up or down
If the number is inside the parenthesis and exponent ex: (x-1)^2 then it decides a movement on the left or right
However inside the parenthesis it is reversed, so a - is move to the right and a + is moved to the left, this making your answer (x-1)^2

Answer:
m < S = 40°
Step-by-step explanation:
According to the Triangle Exterior Angle Postulate, the measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
The exterior angle is m < R = 140°. In reference to the Triangle Exterior Angle Postulate, the sum of the measures of < T and < S must equal 140°.
Given m < T = (8x + 4)°
m < S = (3x + 4)°
We can set up the following equality statement to solve for the value of x:
m < R = m < T + m < S
140° = (8x + 4)° + (3x + 4)°
Combine like terms:
140° = 11x + 8
Subtract 8 from both sides:
140° - 8 = 11x + 8 - 8
132° = 11x
Divide both sides by 11:
132°/11 = 11x/11
12 = x
Substitute the value of x into the equality statement to verify whether it is the correct value:
140° = (8x + 4)° + (3x + 4)°
140° = [8(12) + 4]° + [3(12) + 4]°
140° = (96 + 4)° + (36 + 4)°
140° = 100° + 40°
140° = 140° (True statement. Therefore, the correct value for x = 12).
Therefore, m < S = (3x + 4)° = [3(12) + 4]° = 40°

Answer:
6[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
First, we can start by figuring out how many nails can be produced by 1 machine in 15 minutes. Since 3 machines can produce 16 [tex]\frac{1}{5}[/tex] nails per 15 minutes, we can figure this out by dividing the number of nails produced by 3.
16 [tex]\frac{1}{5}[/tex] divided by 3 equals [tex]\frac{81}{48}[/tex] which can be simplified to 1 [tex]\frac{11}{16}[/tex]. This means that in 15 minutes, one machine can produce 1 [tex]\frac{11}{16}[/tex] nails. Since 15 minutes is 1/4 of an hour, we multiply the nails and minutes by 4, and 1[tex]\frac{11}{16}[/tex] times 4 equals 6[tex]\frac{3}{4}[/tex]. Therefore, 1 machine can produce 6[tex]\frac{3}{4}[/tex] nails in one hour.
