Answer:
x = -2
Step-by-step explanation:
Step 1: Add 10 to both sides.
[tex]x - 10 + 10 = -12 + 10[/tex] [tex]x = -2[/tex]Step 2: Check if solution is correct.
[tex]-2 - 10 = -12[/tex] [tex]-12=-12[/tex]Therefore, x = -2.
The coefficient of x in the expansion of (x+3)(x - 1) is
Answer:
^2+2−3
Step-by-step explanation:
Answer: the coefficient of x in the expansion is 2
Step-by-step explanation:
(x+3)(x-1)= (x)(x) + (x)(-1) + (3)(x) + (3)(-1)
which equals x^2 -x +3x -3 which is x^2 +2x -3
the leading coefficient of x^2 1. and the coefficient of x is 2.

Can someone plsss help me with the circled question tysm if u doo :((
Answer:
4×sqrt(5) inches
Step-by-step explanation:
Pythagorean theorem states that (for right triangles) if you square each shorter side and add those together, you will get the sum of the longest side (hypotenuse) squared.
This is commonly written as:
a^2 + b^2 = c^2, where c is the hypotenuse.
((For right triangles this will always be opposite the 90° angle.))
Since you know one of the shorter sides and the hypotenuse, rewrite the equation as such:
c^2 - b^2 = a^2, where a is the unknown length
This goes to:
sqrt(c^2 - b^2) = a
sqrt((12in)^2 - (8in)^2) = a
sqrt(144sqin - 64sqin) = sqrt(80sqin) = a
This simplifies to:
sqrt(16sqin)×sqrt(5sqin) = 4in×sqrt(5sqin) = a
After swimming to a depth of 55 feet below the surface of
the water, a fish swims back up 30 feet. Use a number line
a
to help you create an equation that shows the new location
of the fish in relation to the water's surface.
-80 -70 -60 -50 -40 -30 -20 -10 0
10
Interpret the sum in the context of the problem.
A. The equation is -55 +(-30) = -85. The fish is 85 feet below
the water's surface.
O B. The equation is -55+ 30 = -25. The fish is 25 feet below the
water's surface.
C. The equation is -55+ (-30) = -25. The fish is 25 feet below
the water's surface.
D. The equation is -55+ 30 = -85. The fish is 85 feet below the
water's surface.
Answer:
Your answer to this question is B. The equation is -55 + 30 = -25. The fish is 25 feet below the water's surface.
Step-by-step explanation:
Hope this helps!

what is the y-intercept from the following?
Answer:
the y intercept is -3
Step-by-step explanation:
if you need an explanation lmk!
Answer:
y- intercept = - 3
Step-by-step explanation:
The y- intercept is where the line crosses the y- axis.
This occurs when the x- coordinate is zero
From the table
when x = 0 , then y = - 3 ← y- intercept

Toby picks a 4-digit number.
It is larger than 2999 and it is a multiple of 2.
How many different numbers could he have picked?
Let’s reduce this question into easier terminology.
The number is a multiple of 2, meaning it is an even number. It is larger than 2,999 and less than 10,000 (since it is a 4 digit number).
Thus, Toby could have picked any even number from 3000 to 9,999. So this question is asking how many even numbers (multiples of 2) are between 3000 and 9,999.
For every thousand, there are 1000/2 = 500 multiples of 2:
500 multiples between 3,000 and 3,999
500 multiples between 4,000 and 4,999
and so on until 9,999. So there are
7*500 = 3500 multiples of 2 in this range.
Toby could have picked 3500 possible numbers.
Which of the following customary units is the most appropriate unit to measure the capacity of a coffee pot?
A. gallon
B. pound
C. ounce
D. cup
Answer:
Cup
Explanation:
Gallon is too large, it'll spill over.
Pound is just... Obviously not. You use that to weight people...
And ounce is smaller than a cup but we're talking about the most appropriate unit therefore your answer is cup.

which one is the steepest
A. 1/2
B. 0
C. 3/4
D. 5
Answer:
3/4
Step-by-step explanation:
Remember: rise/run, where rise is the vertical line and run is the horizontal. To calculate for 5, the rise must be 5x the run (e.g. 25/5). 0 is a horizontal line, since it has no y-axis. Then draw all your lines on a graph. The steepest slope will be 3/4.
Explanation:
Assuming those given answer choices represent slope values, the steepest slope is the number furthest from 0 on the number line. In other words, it will have the largest absolute value.
In this case, the steepest slope is 5 since this value is furthest from 0 of the other answer choices.
