If f(x)=x^2+x, find f(-3)
Answer:
f(-3) = (-3)^2 + (-3) = 9 - 3 = 6
Answer:
I believe the answer is 6
Step-by-step explanation:
1) If f(-3), x is equal to -3 ( I think )
2) f(x) = -3^2 + (-3)
3) f(x) = 9 - 3
4) f(x) = 6
The answer is f(x) = 6

Answer:
Move the decimal point in 407.26 three places to the left = 0.407283
Step-by-step explanation:
Answer:
3, left
Step-by-step explanation:
When you're dividing a number by any power of 10 that is a whole number (10, 100, 1000, etc.), you move the decimal point to the left as many times as there are zeroes in the digit.
Examples:
30.22 ÷ 100 = 0.3022
There are two zeroes in 100, so move the decimal point two spaces to the left.
568.9 ÷ 10000 = 0.05689
There are four zeroes in 10000, so move the decimal point four spaces to the left.
The given equation in the problem is 407.26 ÷ 1000, so you move the decimal point 3 spaces to the left to find the correct answer.

Answer:
51.5; the originStep-by-step explanation:
TranslationFor the translation find the distance between corresponding points of A and A'. It is 5 units.
DilationWe see the figures A' and A'' are symmetrical and the sides on the x-axis overlap. It means the center of dilation is the origin, the point (0, 0).
Find the scale factor by dividing the corresponding x- or y- coordinate of A'' to the one of A'.
Take points (-2, 0) of A' and (-3, 0) of A''.
The scale factor is:
k = -3/-2 = 1.5Solve 31-X + (2 x + 1)] = x - 1.
Answer:
x = X + 33 (I am guessing "x" and "X" are not the same. "x" is a variable and "X" is a constant.)
Step-by-step explanation:
31 - X + (2x+1) = x - 1
or, 2x+1 = x - 1 - 31 + X
or, 2x - x = -1 -31 + X -1
or, x = -2 -31 + X
or, x = X - 33

Solve for the rate (as a %). Round to the nearest tenth of a percent when necessary,
$7.30 is what percent of $58.20?
In accordance with the query, we have 12.6% of $58.20. The closest tenth of one percent.
What percentage is 20%?It really is 100 * 20 / 100 = 20percent . In this circumstance, percentages are useful. When describing a change from one % to another, we use percentage points. The difference between 10% and 12% is four percent respectively (or 20 percent).
Solve for the rate (as a %). Round to the nearest tenth of a percent when necessary, we have following :
$7.30 is what percent of $58.20.
rate = (7.30 / 58.20) * 100
rate = 0.126034483 * 100 = 12.6%
Rounding to the nearest tenth of a percent, the rate is 12.6%.
So $7.30 is 12.6% of $58.20.

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
P(A) = 0.42, P(B) = 0.5
As, events A and B are independent.
so, P(A and B)
= P (A) . P(B)
= 0.42 x 0.5
= 0.21
Hence, the value of P(A and B) = 0.21

MULTIPLE CHOICE:
Jen and David owe $21,000 in loans for their two cars. The amount of the loan for Jen's car is $2,000 less than twice the amount of the loan for David's car. How much is each car loan? (Let j represent the amount of Jen's loan and let d represent the amount of David's loan.)
A. d + j = 21,000
2d − 2,000 = j
B. j + d = 21,000
2j − 2,000 = d
C. j + d = 21,000
2j + 23,000 = d
D. j + d = 2,000
2j − 21,000 = d
E. d + j = 2,000
2d − 21,000 = j
9514 1404 393
Answer:
A. d + j = 21,000; 2d − 2,000 = j
d = $7,666.67; j = $13,333.33
Step-by-step explanation:
The relationships given in the problem statement are ...
d + j = 21,000 . . . . . the total of the two loans is $21,000
2d -2000 = j . . . . . . Jen's is $2000 less than twice David's
__
These equations can be solved by substituting for j:
d +(2d -2000) = 21000
3d = 23000 . . . . . . . . . . . add 2000, collect terms
d = 23000/3 = 7666.67 . . . divide by the coefficient of d
j = 21000 -d = 21000 -7666.67 = 13333.33
Jen's loan is $13,333.33; David's loan is $7,666.67.
A coin is tossed and a die is rolled. What is the probability of tossing heads and rolling either a 5 or 6?
Answer:
The probability of tossing heads and rolling either a 5 or 6 is possible (or unlikely). This because the probability of tossing heads is 1/2 and the probability of rolling a 5 or 6 is 1/6 so combined would be unlikely.
A figure has been dilated from center O by a scale factor of r = 3/10 scale factor would magnify the dilated figure back to the original size?
Answer: The new scale factor needs to be 10/3
Explanation:
Consider a line segment that is 10 units long. Apply the scale factor 3/10 to it, and now it's 3 units long because (3/10)*10 = 3.
To get it back to 10 units, we multiply by the scale factor 10/3 which is the reciprocal of the original scale factor. Note that (3/10)*(10/3) = 1. Those two scale factors multiply to 1 to indicate no change has been made overall.
what is the slope of (29,11) and (-3,-7)
Answer:
The slope is [tex]\frac{9}{16}[/tex]
Step-by-step explanation:
Hi there!
We are given the points (29, 11) and (-3, -7), and we want to find the slope of them.
The slope can be calculated from two points with the slope formula, which is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.
We have two points given, but let's label their values to avoid any confusion when we actually calculate:
[tex]x_1=29\\y_1=11\\x_2=-3\\y_2=-7[/tex]
Now substitute into the formula (m is the slope).
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-7-11}{-3-29}[/tex]
Subtract
m=[tex]\frac{-18}{-32}[/tex]
Reduce the fraction
m=[tex]\frac{9}{16}[/tex]
The slope is [tex]\frac{9}{16}[/tex]

Answer:
The slope is -5/3.
The y-intercept is (0,10).
Step-by-step explanation:
1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.
2. Since -5/3 is in the place of m, the slope, that makes -5/3 the slope.
3. The y-intercept of a graph is the point where the graph intersects/crosses the y-axis. The x-coordinate of a point in any y-intercept will ALWAYS be 0.
4. Since 10 is in the place of b, the y-intercept, and given the information above, the y-intercept is (0,10).

6th grade students took a survey on their favorite subject.
The ratio of students whose favorite subject was Science to
students whose favorite subject was Math was 3:5. If 238
more students picked Math as their favorite subject, how many
students picked Science as their favorite subject?
Using a system of equations, it is found that 595 students picked Science as their favorite subject.
For our system, we suppose that x is the number of students that picked science, and y is the number of students that picked math.
Ratio of science to math of 3:5, thus:
[tex]\frac{x}{y} = \frac{3}{5}[/tex]
Then
[tex]5x = 3y[/tex]
[tex]x = \frac{3y}{5}[/tex]
238 more students picked Math as their favorite subject, thus:
[tex]y = 238 + x[/tex]
[tex]y - \frac{3y}{5} = 238[/tex]
[tex]\frac{2y}{5} = 238[/tex]
[tex]y = \frac{238(5)}{2}[/tex]
[tex]y = 595[/tex]
595 students picked Science as their favorite subject.
