Answer:
-1.28
Step-by-step explanation:
You would put these two equations into a graphing ccalculator:
y = -4x - 1
and
y= 5^x + 4
Wherver they intersect is your answer.
These two happen to intersect at (-1.28,4.13)
Since the equation has x-values, you would give the first number (x-coordinate) as your answer.

Mrs. Garcia's math test is worth 50 points. If you answer all questions and extra credit correctly, you can score 55 points. How do you represent this situation as a fraction, a decimal, and a percent?
Amplitude of 16 units, a period of 5 units, a vertical displacement of 3 units up and a phase shift of 2.5 units left.
The question is incomplete. The complete question is :
A sine function that has an amplitude of 16 units, a period of 5 units,a vertical displacement of 3 units up and a phase shift of 2.5 units left. Graph this function and show each step.
Solution :
The standard form of the sine function is
y = a sin (bx - c) + d
Here given :
Amplitude, a = 16
Period : [tex]$\frac{2 \pi}{|b|} = 5$[/tex]
⇒ [tex]$b = \frac{2\pi}{5}$[/tex]
Phase shift : [tex]$\frac{c}{b} = 2.5$[/tex]
[tex]$\Rightarrow \frac{c}{2 \pi/5}=\frac{5}{2}$[/tex]
∴ [tex]$c = - \pi$[/tex]
The vertical displacement : d = 3 units up
Now substituting a, b, c and d values in the standard form gives :
[tex]$y = 16 \sin \left( \frac{2 \pi}{5}x -(- \pi)\right) + 3$[/tex]
[tex]$y = 16 \sin \left( \frac{2 \pi}{5}x + \pi\right) + 3$[/tex]
The graph is attached below.
Write a linear function f with the given values.
f(x) =
Answer:
f(x) = -2x + 1
Step-by-step explanation:
What is the slope of the line that passes through the points (-4, -2)and (−4,−22)? Write your answer in simplest form.
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
From the question we have
[tex]m = \frac{ - 22 - - 2}{ - 4 - - 4} = \frac{ - 22 + 2}{ - 4 + 4} = - \frac{20}{0} \\ [/tex]
Any number divided by zero is undefined so the slope of the line is undefined.
Hope this helps you
Answer:
Undefined ([tex]\infty [/tex])Step-by-step Explanation:
We need to find the slope of the line joining the points (-4, -2) and (-4, -22).
We know that, Slope is the difference of abcsissa (x - coordinate) / difference of ordinates (y-coordinate)
[tex]m = \dfrac{y2 - y1}{x2 - x1} [/tex]
Here:
x1 = -4x2 = -4y1 = -2y2 = -22Plugging these values:
[tex]m = \dfrac{ - 22 - ( - 2)}{ - 4 - ( - 4)} [/tex]
This can be written as:
[tex]m = \dfrac{ - 22 + 2}{ - 4 + 4} [/tex]
[tex]m = \dfrac{ - 20}{0} = \infty [/tex]
Here, The slope of the line is infinite or undefined. An undefined slope (or an infinitely large slope) is the slope of a vertical line!

A bricklayer can build a wall of a certain size in 5 hours. Another bricklayer can do the same job in 4 hours. If the bricklayers work together, how long would it take to do the job?
a. 9h
b. 2(2/9)h
c. 20h
d. 4(1/2)h
Answer:
b
Step-by-step explanation:
It will take [tex]\frac{20}{9}[/tex] hours as per linear equation to complete the wall.
What is a linear equation?A linear equation is an equation where the variable of the equation has the highest power of degree one.
Given, the 1st bricklayer build a complete wall of certain size in 5 hours.
Therefore, that bricklayer build [tex]\frac{1}{5}[/tex]th of the complete wall in 1 hour.
Similarly, the 2nd bricklayer build a complete wall of certain size in 4 hours.
Therefore, that bricklayer build [tex]\frac{1}{4}[/tex]th of the complete wall in 1 hour.
If they work together, in 1 hour they build a total of ([tex]\frac{1}{5}[/tex]+[tex]\frac{1}{4}[/tex])th = [tex]\frac{9}{20}[/tex] of the complete wall.
Hence, they will complete the wall in (1÷[tex]\frac{9}{20}[/tex]) hours = [tex]\frac{20}{9}[/tex] hours.

Triangle ABC is a right triangle. The length of the legs are 3 in and 6 in, how long is the hypotenuse? (Round to the nearest tenth if necessary)
A) 3.3 in
B) 6.7 in
C) 7.9 in
D) 9.0 in
Triangle ABC is a right triangle. The length of the legs are 3 in and 6 in, how long is the hypotenuse? (Round to the nearest tenth if necessary)
When the two legs are given, the hypotenuse is found by using the Pythagorean Theorem, which states that:
[tex]\displaystyle a^{2} +b^{2} =c^{2}[/tex]
In the theorem, a and b are the two legs, and c is the hypotenuse. Since you are given the length of the two legs, substitute it into the equation.
[tex]a=3\\b=6[/tex]
[tex]3^{2} +6^{2}=c^{2}[/tex]
Now, you need to square both 3 and 6. When you square a number, you're basically multiplying the number by itself.
[tex]3^{2} =3 \times 3=9\\6^{2}=6 \times 6=36[/tex]
Substitute the numbers into the equation.
[tex]9+36=c^{2}[/tex]
Add:
[tex]45=c^{2}[/tex]
You're looking for the value of c, not c squared. To remove the square, you need to square root it.
[tex]\displaystyle \sqrt{45}=\sqrt{c^{2} }[/tex]
Using a calculator, find the square root of 45.
[tex]\displaystyle \sqrt{45}=\sqrt{c^{2} }\\c \approx 6.7[/tex]
The answer to your question is B) 6.7 inches.
Answer: A
Step-by-step explanation:
Use Pythagorean Theorem in order to solve this:
[tex]a^{2} + b^{2} = c^{2}[/tex]
(c is the hypotenuse)
So that would be:
[tex]3^{2} + 6^{2} = c^{2}[/tex]
If you solve this, you would find that:
[tex]c^{2} = 45[/tex]
[tex]c = 3\sqrt{5}[/tex]

Equivalent ratios are ratios that contain different numbers but express the same relationship between the quantities they're comparing. Ratios are equivalent if there's a positive number that can be multiplied by both quantities in one ratio to get the corresponding quantities in the second ratio. For example, imagine you're making hot sauce that calls for chile peppers and tomatoes in a ratio of 1:2. If you put in 1 chili pepper, you'll need to put in 2 tomatoes. If you put in 2 chili peppers, you'll need to put in 4 tomatoes to keep the ratio the same. You can multiply both numbers in the first ratio by 2 to get the corresponding numbers in the second ratio: 1 × 2 = 2 2 × 2 = 4 The ratios show the same relationship between chili peppers and tomatoes. Which of these ratios is equivalent to 2:3? A 2:6 B 4:6 C 3:2 D 3:4
Answer:
B 4:6

The distance on a map from Lynchburg to Houston is 5 in. The scale on the map is 1/2 in = 100 mi. What is the actual distance?
A) 100 mi
B) 10,000 mi
C) 1000 mi
Answer:
1,000 miles
Step-by-step explanation:
set up the equation as
100x = d
where x equals the number of half inches between two points on the map
and d equals the distance between those points in real life
5 inches = 10 half inches so, plugged in the equation looks like
100(10) = d
simplify it to
1000 = d
and bam, the real distance is 1,000 miles

Answer:
9/40
Step-by-step explanation:
He needs 5/8, he already has 2/5, so still needed is 5/8-2/5.
To add or subtract fractions, the denominators must be equal.
Simplest approach is to multiply them. 8 times 5 is 40, so 40 is the new denominator we need for both fractions.
So first we convert 5/8 to 25/40.
Then we convert 2/5 to 16/40.
Now we can subtract them:
25/40 - 16/40 = 9/40.
9/40 cannot be simplified so this is the final answer.
There are some basic rules you need to know to work with fractions. If above work is too fast, comment below for deeper explanation.
