Answer:
-51 + 60
Step-by-step explanation:
When subtracting with negative numbers use the "keep, change opposite" skill. Keep your first number which in this case, is -51, then change the subtraction sign to addition and lastly change the sign of your last digit which is (-60) so opposite of that just 60.

write the equation of the line that passes through the points (-3,4) and (-4,2). Write the final answer in slope intecept form
Answer:
The equation in the slope-intercept form will be:
[tex]y=2x+10[/tex]
Step-by-step explanation:
Given the points
(-3, 4)(-4, 2)Finding the slope between two points
[tex]\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(-4,\:2\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{2-4}{-4-\left(-3\right)}[/tex]
[tex]m=2[/tex]
As the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
putting the values m=2 and the point (-3, 4)
[tex]y-4=2\left(x-\left(-3\right)\right)[/tex]
[tex]y-4=2\left(x+3\right)[/tex]
Writing the equation in slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope, and b is the y-intercept
so the equation becomes
[tex]y-4=2\left(x+3\right)[/tex]
add 4 to both sides
[tex]y-4+4=2\left(x+3\right)+4[/tex]
[tex]y=2x+10[/tex]
Therefore, the equation in the slope-intercept form will be:
[tex]y=2x+10[/tex]

A state lottery game requires that you pick 6 different numbers from 1 to 44. What is the probability of picking exactly 3 of the 6 numbers correctly?
Answer:
Step-by-step explanation:
This would be a sequence of events therefore, in order to calculate this you would simply need to multiply together the probability of each event happening seperately. The probability of getting a correct number is 1/44 while the probability of getting an incorrect number is 43/44. Therefore, since we need to find the probability of getting only 3 out of the six correct we would multiply the following.
[tex]\frac{1}{44} * \frac{1}{44} * \frac{1}{44} * \frac{43}{44} *\frac{43}{44} *\frac{43}{44} =[/tex] 0.000001095 or [tex]\frac{79,507}{7,256,313,856}[/tex]

What is the solution set for StartAbsoluteValue y minus 9 EndAbsoluteValue less-than-or-equal-to 12:A?

Negative 3 less-than-or-equal-to y less-than-or-equal-to 21
y greater-than-or-equal-to negative 3 or y less-than-or-equal-to 21
3 less-than-or-equal-to y less-than-or-equal-to 21
Using the absolute value concept, it is found that the solution is:
[tex]-3 \leq y \leq 21[/tex]Which is given by the second option.---------------------------------
The absolute value of a point, or of a function, measures it's distance to the origin.The inequality given by:
[tex]|y - 9| \leq 12[/tex]
The distance to the origin is of at most 12 between -12 and 12, thus:[tex]-12 \leq y - 9 \leq 12[/tex]
We have to solve both inequalities, and find the intersection.[tex]-12 \leq y - 9[/tex]
[tex]-y \leq 3[/tex]
[tex]y \geq -3[/tex]
[tex]y - 9 \leq 12[/tex]
[tex]y \leq 21[/tex]
The intersection is values of y between -3 and 21(and logical operator, not or), inclusive, thus: [tex]y \geq -3[/tex] and [tex]y \leq 21[/tex], that is: [tex]-3 \leq y \leq 21[/tex]A similar problem, involving absolute value, is given at https://brainly.com/question/24734454

125 is what percent of 50?
Answer:
250%
Step-by-step explanation:
For this equation we have to use the percent composition formula. It is as follows:
[tex]\frac{part}{whole} *100 = percent[/tex]
Now, we plug in the numbers given in the equation. 125 being the part and 50 being the whole.
[tex]\frac{125}{50} *100 = 250[/tex]
Therefore, 125 is 250% of 50.
Hope this helps!!

The percentage of 125 in whole quantity 50 is, 250%
What is the percentage?Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".
To find what percentage 125 is of 50, we first need to convert the ratio of 125 to 50 into a decimal and then convert the decimal into a percentage.
The ratio of 125 to 50 can be expressed as a fraction: 125/50. We can convert this fraction to a decimal by dividing the numerator by the denominator:
⇒ 125/50
⇒ 2.5
Next, we convert the decimal to a percentage by multiplying it by 100 and adding the percent symbol:
⇒ 2.5 x 100
⇒ 250%
So, 125 is 250% of 50. This means that 125 is equal to 250% of the value of 50.

Answer:
d = [tex]\pi[/tex]
e = [tex]-\sqrt{8}[/tex]
f = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
D is equal to pi because pi is 3.1415... Therefore we need a point that is a little more than -3 and that is point d.
[tex]-\sqrt{8}[/tex] is roughly equal to -2.8 because 3 * 3 = 9 so that is too much, and 2 * 2 = 4 is too little so it has to be between -2 and -3. Therefore the point is e.
For 3/2 it has to be less than 2 because 2 cannot go into 3 more than once. The point would then be point f.

A person runs 1 4/5 miles in 1/5 of an hour determine how many miles they are running per hour
Answer:
Step-by-step explanation: There are different methods to solve this, but I chose to change these into decimals- 1.8 and .20, to make it easier. Since miles per hour is speed, and speed is distance divided by time, all you have to do is fill in the blanks.
Since 1.8 / .20= 9, the answer is 9 miles per hour.
To take it a step farther, you could multiply this by any number of hours, or convert it to minutes. For example, to figure out how far they'd get in 10 minutes, I could divide the unit rate by 60, since there are 60 minutes in an hour, and get 0.15. So, in 10 minutes, they'd get 0.15 miles away.

Which equation describes this line!!
Answer:
Option A: y-9=2(x-1)
Step-by-step explanation:
Notice that the answer choices are in point-slope form which is y-y1=m(x-x1)
The slope, m, is (9-3)/(1-(-2))=6/(1+2)=6/3=2, but that's given anyway.
Option A would be right because y1=9 and x1=1 which is where the line crosses through (1,9)
B is not right because that would suggest the line crosses (2,3) as y1=3 and x1=2, but it actually crosses (-2,3) so it should've been y-3=2(x+2)
C and D are wrong because the points aren't crossed through

We can use the fact that in a triangle, the side opposite the smallest angle is the shortest side.
So we need to determine which angle is the smallest.
Now,
In ΔQRS,
m∠Q = 63º, m∠R = 70°, and m∠S= 47°
Now,
m∠S= 47° is the smallest.
So,
QR is the side opposite to m∠S.
Thus,
QR is the shortest side.
