{4x+2y=10
y=2x-1
What is the value of x+y
A.3.125
B.2
C.4.5
D.3.5
Answer:
D.3.5
Step-by-step explanation:
4x+2y=10(given)
2x+y=5
y=5-2x-----(1)
y=2x-1------(2)(given)
Since the left side of the equations are the the same,
5-2x=2x-1
4x=6
x=1.5
Sub x=1.5 into eq(1),
y = 5-2(1.5) = 5-3 = 2
so, x+y = 1.5+2 = 3.5
Answer:
4x+2y=10
y=2x-1
4x+2(2x-1)=10
4x+4x-2=10
8x=10+2
8x=12
8x÷8=10÷8
x=1,25
&
y=2x-1
=2(1.25)-1
=1.5
x+y=1.25+1.5
=2,75

The electricity to run a refrigerator for a week costs $6.30. How much does it cost to run the refrigerator for 365 days?
Answer: 327.60 dollars
Explanation:
There are about 52 weeks in a year (note that 365/7 = 52.14)
So that means it costs a total of 52*6.30 = 327.60 dollars to run the fridge for a full year.
Answer:
It costs $328.50 to run the refrigerator for 365 days
Step-by-step explanation:
Recall that there are seven days in a week and 52 weeks in a year
The given rate is
$6.30
-----------
7 days
To find the cost of running the refrigerator for 365 days, multiply this given rate by 365 days:
$6.30
----------- * 365 days = $328.50
7 days
It costs $328.50 to run the refrigerator for 365 days (1 year, 52 weeks).
What is the volume of the prism shown?
A) 149.9 cubic inches
B) 268.2 cubic inches
C) 173.9 cubic inches
D) 291.8 cubic inches
Answer:
145.9 cubic inches
Step-by-step explanation:
The volume of a triangular prism is:
1/2 x length x width x height
Use the formula with the given dimensions:
1/2 x 5.27 x 8.13 x 6.81 = 145.8875655

in triangle PQR, m angle R = 32, p = 21, and q = 21. what is side lenth r? explain each step
Answer:
11.577 = r
Step-by-step explanation:
Comment
When you draw a sketch of this, <R is between p and q - - both of which are lines. The Cos law is the one you use.
Equation
r^2 = p^2 + q^2 - 2pq * Cos(R)
Givens
p = 21
q = 21
R = 32
r = ?
Solution
r^2 = 21^2 + 21^1 - 2*21*21 * Cos(32) Substitute givens into the equation
r^2 = 441 +441 - 882 * 0.8480 Add the first two terms.
r^2 = 882 - 747.98 Multiply Cos(32) by 2 * 21 * 21
r^2 = 134.02 Subtract 747.98 from 882
sqrt(r^2) = sqrt(134.02) Take the square root of both sides.
r = 11.577

Use the function f(x) = 4x^2 - 7x - 15 to answer the questions.
Part a: completely factor f(x).
Part b: what are the x-intercepts of the graph of f(x)? Show your work.
Part C: describe the end behavior of the graph of f(x). Explain.
Part D: what are the steps you would use to graph f(x)? Justify that you can use the answers obtained in part B and part C to draw the graph.
9514 1404 393
Answer:
a. f(x) = (4x +5)(x -3)
b. x-intercepts: {-1.25, +3}
c. f(x) goes to +infinity as x goes to ±infinity
d. plot the x-intercepts, the vertex, and a few other points; draw a smooth curve through them
Step-by-step explanation:
a. Here, you're looking for factors of (4)(-15) = -60 that have a sum of -7. Those factors will be -12 and +5, so we can factor the function as ...
f(x) = (4x -12)(4x +5)/4
f(x) = (x -3)(4x +5)
__
b. The x-intercepts are the values of x that make the factors zero:
x -3 = 0 ⇒ x = 3 . . . . (add 3)
4x +5 = 0 ⇒ x = -5/4 . . . . (add -5, divide by 4)
__
c. As with all even-degree polynomials with positive leading coefficients, the end behavior of f(x) matches that of |x|:
as x → ∞, f(x) → ∞
as x → -∞, f(x) → ∞
__
d. The vertex of the function will be located halfway between the x-intercepts, at x = (3-5/4)/2 = (7/4)/2 = 7/8. The value of f(x) there is ...
f(7/8) = (4(7/8) +5)(7/8 -3) = -289/16 = -18.0625
Since the leading coefficient is 4, the normal x^2 function behavior is stretched vertically by a factor of 4. So, additional points would be
x = 7/8 ±1, f(x) = -18.0625 +4·1 = -14.0625
x = 7/8 ±2, f(x) = -18.0625 +4·2^2 = -2.0625
The answers of part B locate two points on the graph, and help find the vertex. The answer of part C confirms the graph as opening upward.

I find a graphing calculator to be very helpful finding the roots and making the graph.
the sum of 25 and x is 48 find x. . Solve.
Answer:
x = 23
Step-by-step explanation:
Sum of 25 and x = 48
25 + x = 48
Subtract 25 from both sides
25 - 25 cancels out
48 - 25 = 23
We would be left with x = 23
Answer:
[tex]x =23[/tex]
Step-by-step explanation:
Sum of 25 and x
[tex]25 + x[/tex]
Sum of 25 and x is 48
[tex]25 + x = 48[/tex]
Now lets simply Solve the equation
[tex]25 + x = 48 \\ x = 48 - 25 \\ x =23[/tex]
Hope this helps you.

A silo in the shape of a cylinder is partially filled with corn to feed cows. The corn fills 25% of the height of the silo. What is the approximate volume of the part of the silo that is filled with corn if the silo is 12 feet in diameter and 60 feet high?
- PLEASE HELP im in the middle of an exam
Answer:
1695.6 cubic feet
Step-by-step explanation:
Given that,
The corn fills 25% of the height of the silo.
The diameter of silo, d = 12 feet
Radius, r = 6 feet
Height, h = 60 feet
The volume of the part of the silo that is filled with corn is given by :
[tex]V=25\%\ of\ \pi r^2 h\\\\=\dfrac{25}{100}\times 3.14\times 6^2\times 60\\\\V= $$1695.6\ feet^3[/tex]
So, the required volume is equal to 1695.6 cubic feet.

A trapezoid has height 20 inches. Its bases have sum 30 inches, and one base is 6 inches longer than the other. What is the area of this trapezoid?
Answer:
300 square inches
Step-by-step explanation:
Area of a Trapezoid = 1/2 (b1 + b2 ) × h
h = height 20 inches
b1 = First base = ?
b2 = Second base = ?
From the Question
b1 + b2 = 30 Inches
Hence,
Area of the Trapezoid = 1/2 (30) × 20
= 1/2 × 30 inches × 20 inches
= 300 square inches
The Area of the Trapezoid = 300 Square inches
