Heather has divided $5600 between two investments, one paying 9% the other paying 5%. If the return investment is $396, how much does she have in each investment?
Answer:
x = 2700 y=2900
Step-by-step explanation:
x+y = 5600
5/100 x + 9/100 y = 396
x+y=5600
5x+9y=39600
5x+5y = 28000
5x+9y=39600
-4y = -11600
y= 2900
x = 5600-2900 = 2700
a = 5bc

A student wants to arrange four points to form a rectangle on a grid. She has already placed points at Syntax error. Where should she place the last point? PLEASE HURRRY
Question:
A student wants to arrange four points to form a rectangle on a grid. She has already placed points at (-4. 4). (-4, 8). and (4, 8). Where should she place the last point?
Answer:
[tex]D = (4,4)[/tex]
Step-by-step explanation:
Let the rectangle be ABCD
[tex]A = (-4,4)[/tex]
[tex]B= (-4,8)[/tex]
[tex]C = (4,8)[/tex]
Required
Determine the location of the last point
A rectangle has the following coordinates
[tex]A = (x_1,y_1)[/tex]
[tex]B = (x_1,y_2)[/tex]
[tex]C = (x_2,y_2)[/tex]
[tex]D = (x_2,y_1)[/tex]
From the given coordinates:
[tex]x_1 = -4[/tex] --- see x coordinates of A and B
[tex]x_2 = 4[/tex] --- see x coordinates of C
[tex]y_1 =4[/tex] --- see y coordinates of C
[tex]y_2 =8[/tex] --- see y coordinates of B and C
So:
[tex]D = (x_2,y_1)[/tex]
[tex]x_2 = 4[/tex]
[tex]y_1 =4[/tex]
The coordinates of the last point (D) is:
[tex]D = (4,4)[/tex]

Sekhar gives a quarter of his sweets to Renu and then gives 5 sweets to Raji. He has
7 sweets left. How many did he have to start with?
Answer:
16 sweets
Step-by-step explanation:
Number of sweet that Sekhar had = x
Sweets given to Renu = (1/4) of x = [tex]\frac{1}{4}x[/tex]
Sweets given to Raji = 5
Remaining sweets = 7
[tex]x = \frac{1}{4}x +5 + 7\\\\x -\frac{1}{4}x = 12\\\\\frac{4*x}{1*4}x-\frac{1}{4}x = 12\\\\\frac{4x}{4}-\frac{1}{4}x= 12\\\\\frac{3x}{4}=12\\\\x = 12*\frac{4}{3}\\\\x=4*4\\\\x=16[/tex]

What is the y-intercept of function g if g(x) = 2f(x) + 1 ?
A. (0,2)
B. (0,-1)
C. (0,3)
D. (0,1)
By evaluating the function in x = 0, we will see that the y-intercept is (0, 3), so the correct option is C.
How to find the y-intercept of a function?
The y-intercept of a function g(x) is given by evaluating the function in x = 0.
So the y-intercept of g(x) is:
y = g(0).
In this case, we have:
g(x) = 2f(x) + 1
The y-intercept will be:
g(0) = 2*f(0) + 1
By looking at the graph, we can see that f(0) = 1, replacing that above we get:
g(0) = 2*1 + 1 = 3
Then the y-intercept is the point (0, 3), meaning that the correct option is C.

What is the slope of the line?
What is the y-intercept?
Write the equation of the line
Answer:
slope is 2
y-intercept is 3
equation y=2x+3
Step-by-step explanation:
Answer:
slope=4/2 or 2
y-intercept=3
equation=y=2x+3
the slope would be 4/2 because if you do the triangle method you see that the vertical distance of y is 4 and the horizontal distance of x is 2 so that gives you 4/2 the y intercept is where the line starts at 0 which you can see is 3. if the equation is y=mx+b you plug in the slope which is 4/2 or 2 and plug in the y-intercept which is 3 which gives you y=2x+3

Find the value of the expression below for x=3
x^2+5
Answer: 14
Step-by-step explanation: 3 to the second is 3 twice EX. 3x3=9, 9+5=14
Answer: x= −5 /2 + 1 /2 √37 or x= −5 /2 + −1 /2 √37
Step-by-step explanation:
Step 1: Subtract 3 from both sides.
x2+5x−3=3−3
x2+5x−3=0
For this equation: a=1, b=5, c=-3
1x2+5x+−3=0
Step 2: Use quadratic formula with a=1, b=5, c=-3.
x= −b±√b2−4ac /2a
x=
−(5)±√(5)2−4(1)(−3) /2(1)
x= −5±√37 /2
x= −5 /2 + 1 /2 √37 or x= −5 /2 + −1 /2 √37

Find the missing side
Answer:
20
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2, where a and b are the sides and c is the hypotenuse
15^2 + b^2 = 25^2
225 + b^2 = 625
b^2 = 625 -225
b^2 =400
Take the square root of each side
sqrt(b^2) = sqrt(400)
b = 20

Answer:
The equations that are true are
B
C
E
Step-by-step explanation:
A) States that 0 + 451 = 0, but that is not true because...
0 + 451 = 451
B) States that 130 + 210 = 210 + 130, and that is true because...
130 + 210 = 210 + 130
340 = 340
C) States that (127 + 80) + 250 = 127 + (80 + 250), and it is true because...
(127 + 80) + 250 = 127 + (80 + 250)
127 + 80 + 250 = 127 + 80 + 250
457 = 457
D) States that (123 + 57) + 180 = 153 + (87 + 180), but that is not true because...
(123 + 57) + 180 = 153 + (87 + 180)
123 + 57 + 180 = 153 + 87 + 180
360 = 420 (but this does not make sence)
E) States that 497 + 0 = 497, and it is true because...
497 + 0 = 497
497 = 497
Answer:
E is true, B is true, C is true,
Which expression fits this description? • The expression is the quotient of two quantities. • The numerator of the expression is the product of 5 and the sum of x and y. • The denominator is the product of negative 8 and x.
Answer:
[tex]\frac{5(x+y)}{-8x}[/tex]
Step-by-step explanation:
It is a fraction that usually has a numerator and denominator
the numerator is the number on top while the denominator is the number below
[tex]\frac{a}{b}[/tex]
In the above fraction, a is the numerator while b is the denominator
Numerator =5 × ( x + y)
Denominator = -8x ( negative means there is a negative sign before 8)
( product means multiplication)
[tex]\frac{5(x+y)}{-8x}[/tex]
