Write an equation in slope-intercept form for a line parallel to y=4 x-5 containing (-1,5) .
The equation in slope-intercept form is y = 4x + 1
Given,
Points (x, y) = (-1, 5)
Parallel to y = 4x - 5
Now,
Recall that a parallel line to the one given has to have the same slope. The slope of the line given is "4" (the coefficient that accompanies "x").
Therefore the equation of a parallel line has to be of the form:
y = 4x - b
5 = 4(-1) - b
5 = -4 - b
b = -4 - (-5)
b = -4 + 5
b = 1
So the equation now becomes:

Write each statement in if-then form. An acute angle measures less than 90 .
If-then form of the given statement : an acute angle measures less than 90 will be : If an angle is an acute angle, then the angle measures less than 90 degrees.
We can understand this problem by using the above statement as an example like :
If an angle is an acute angle, then the angle measures less than 90 degrees. The part after if : an angle is an acute angle is called a hypotheses and the part after then : the angle measures less than 90 degrees is called a conclusion.
Hypotheses followed by a conclusion is called an If-then statement or a conditional statement.
This is noted as :
p → q
This is read - if p then q.
A conditional statement is false if hypothesis is true and the conclusion is false. The example above would be false if it said "If an angle is an acute angle, then the angle does not measure less than 90 degrees."

X=2 if and only if |x| = 2
True or false? Please answer if you're 100 percent sure.
Answer:
False
Step-by-step explanation:
Let's just analyze it.
x=2 if and only if |x|=2
That can be rewritten as:
if x = 2 then |x| = 2
AND
if |x| = 2 then x = 2
Let's solve each one separately:
we have x = 2
we can simply get |x| by removing the sign, if any. There is none, so |x| = 2.
The first part checks out.
we have |x| = 2
As with absolute values, this means that either x = 2 or x = -2
So we know from |x| that x is either 2 or -2, but the logical statement said "if |x| = 2 then x = 2", which is too specific - it forgets about -2.
The second part is false.
Overall, we now know that "X=2 if and only if |x| = 2" is false because x = -2 is a counterexample. We get: "False if and only if True" which itself is false.

in exercises 14 and 15, the value of the surface area of the cylinder is equal to the value of the cylinder. Find the surface area of the cylinder
Considering that the surface area and the volume of the cylinders are equal, the surface areas are given as follows:
14. 108π ft².
15. 250π ft².
What are the surface area and the volume of a cylinder?For a cylinder of radius r and height h, the surface area is given by:
S = 2πr(h + r).
The volume is given by:
V = πr²h.
For item 14, the parameters are given as follows:
r = 6 ft, h = x ft.
Hence we solve for x equaling the surface area and the volume as follows:
V = S
36πx = 12π(x + 6)
3x = x + 6
2x = 6.
x = 3.
Hence the surface area is:
S = 12π(3 + 6) = 108π ft².
For item 15, the parameters are given as follows:
r = 10 ft, h = x ft.
Hence we solve for x equaling the surface area and the volume as follows:
V = S
100πx = 20π(x + 10)
5x = x + 10
4x = 10.
x = 2.5.
Hence the surface area is:
S = 20π(2.5 + 10) = 250π ft².

Solve each inequality. Check your solution. 4x - 2 > 1/2
The inequality given by 4x - 2 > 1/2 has the solution x > 5/8 or (5/8 , +∞).
Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.
To solve an inequality is to find the values of x such that when we substitute that number for x we have a true statement.
Given the inequality 4x - 2 > 1/2, add 2 to both sides.
4x - 2 + 2 > 1/2 + 2
4x > 5/2
Multiply both sides by 1/4.
1/4(4x) > 1/4(5/2)
x > 5/8
To check, let x = 3/4
x = 3/4 ≥ 5/8

Uranium-238 (U-238) has a half-life of 4.5 billion years. Geologists find a rock containing a mixture of U-238 and lead, and determine that 71% of the original U-238
remains; the other 29% has decayed into lead. How old is the rock?
The rock is ___ billion years old.
(Round to three decimal places as needed.)
Answer: 2.223 billion years old
Step-by-step explanation:
since 71 percent of the rock is remaining, the half life hasn't been reached yet. Hence, we know uranium isn't 4.5 billion years old yet. However, every-time 4.5 billions years pass, the rock get smaller by 2 times(a scale factor of 1/2). Hence, you can express that in a log equation:
[tex]\log_{2}(100/(percent of rock remaining))=[/tex] Fraction of 4.5 billions years of time passed
[tex]\log_{2}(100/50)=1[/tex] ==> 100% of 4.5 billion years passed. When 50% of rock remains, 4.5 billion years have passed.
[tex]\log_{2}(100/100)[/tex] =
[tex]\log_{2}(1)=0[/tex] ==> 0% of 4.5 billion years passed. When the rock hasn't decayed at all yet, that means that it is 0 years old.
[tex]\log_{2}(100/71)=0.494[/tex] ==> 49.4 % of 4.5 billion years passed
0.494*4.5 billion =2.223 billion years passed

∠2 and ∠3 are supplementary; m∠2=149
When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of ∠3 is 31°.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
Given that ∠2 and ∠3 are supplementary angles. Therefore, the sum of the two angles will be 180°. Thus, we can write the sum of the two angles as,
∠2 + ∠3 = 180°
Also, it is mentioned in the question that the measure of ∠2 is 149°. Therefore, substitute the value of ∠2 in the above equation.
149° + ∠3 = 180°
∠3 = 180° - 149°
∠3 = 31°
Hence, the measure of ∠3 is 31°.
