Answer:
x = 13
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex](-2)(x) + (-2)(-5)= -16[/tex] [tex]-2x + 10 =-16[/tex]Step 2: Subtract 10 from both sides.
[tex]-2x + 10 - 10 = -16 - 10[/tex] [tex]-2x = -26[/tex]Step 3: Divide both sides by -2.
[tex]\frac{-2x}{-2}=\frac{-26}{-2}[/tex] [tex]x = 13[/tex]Step 4: Check if solution is correct.
[tex]-2(13-5)=-16[/tex] [tex]-26 + 10 = -16[/tex] [tex]-16=-16[/tex]Therefore, x = 13.
Answer:
x=13
Step-by-step explanation:
-2(x -5) = -16
Divide each side by -2
-2(x -5)/-2 = -16/-2
x-5 = 8
Add 5 to each side
x-5+5 = 8+5
x=13
Find the area under the standard normal curve more than 3.2. Give your answer to 4 decimal places.

Answer:
5/14
Step-by-step explanation:
-9 is just 9 so that makes 9/14 - 2/7.
Multiply 7 by 2 and that makes 14, do the same with the numerator and that makes 4/14 and 9/14 - 4/14 = 5/14

What is the equation in slope-intercept form that has a slope of -1 and a y-intercept of 4?
pls help
Answer:
y= -1x+4
Step-by-step explanation:
y=mx+b
m=slope
b=slope intercept
x=x-intercept
Use the point and the slope to graph cach line. Write the equation of the line.
The line passes through point (-1, 4) and has slope - 2.
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
1. Lucy monitors the position of a large fish in the ocean with a measuring tool. The tool records the depth (how deep the level) of the fish. Initially, the fish swims at a depth of 14 feet below sea level. Suddenly the fish rises 8 feet.

(b) What is the position of the fish after it rises 8 feet relative to sea level? Show your work. Answer in a complete sentence.
Hint: Draw and label a picture to see and show what is happening.
Answer:
A) -14 + 8 = 6
B) The fish is at -6 feet below the sea level after it rises 8 feet because -14 (14 feet below 0) plus the 8 feet it rises is -6 feet or 6 feet below the sea level.

Answer:
3/4; 1/4, 1/4, 1/4
Step-by-step explanation:
The intent here is to let you demonstrate your understanding that multiplication by an integer is the same as repeated addition.
Your knowledge of fractions tells you ...
[tex]\dfrac{1}{4}\times3=\dfrac{3}{4}[/tex]
The factor of 3 means this is equivalent to adding 1/4 a total of 3 times:
[tex]\dfrac{1}{4}\times3=\dfrac{1}{4}+\dfrac{1}{4}+\dfrac{1}{4}[/tex]
A hamburger shop sold a combined total of 304 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold?
Answer: 76 hamburgers
Step-by-step explanation:
first we will write an equation:
x+3x=304
which simplified turns in 4x=304
x=76
now go back to our equation and solve.
3x is cheese burgers= 228 cheeseburgers
x is hamburgers =76 hamburgers
