You and a friend go to Tacos Galore for lunch. You order three soft tacos and five burritos and your total bill is $17.75. Your friend orders four soft tacos and two burritos and paid $12.00.
Answer:
Step-by-step explanation:
let tacos be x and burritos be y
so, your 1st eqn. is 3x + 5y = 17.75
2nd eqn. is 4x+ 2y = 12
Solving the 2 eqns: Multiply eqn 1 with 2 and eqn 2 with 5
So: 6x+10y=35.5
-20x-10y=-60
=-14x=-24.5
x=24.5/14 = 1.75
Substituting the value of x in eqn 1 : (3*1.75)+5y=17.75
y = 2.5
evaluate function expression 5xf(1) + 5xg(9)
Answer:
5x(f+9g)
Step-by-step explanation:
5xf(1)+5xg(9)
Factor out 5.
5(xf+9xg)
Consider xf+9xg. Factor out x.
x(f+9g)
Rewrite the complete factored expression.
5x(f+9g)

Evaluate the expression x3 + y2 for x =2 and y= -3
Answer:
Assuming that its x^3 + y^2, the answer would be 17.
Step-by-step explanation:
Replace x or y with its number.
(2)^3 + (-3)^2
8 + 9

Answer:
(0,-9), x = 0, (-3,0), (3,0), domain, -9
Step-by-step explanation:
Complete the square and you can read everything off the equation,
y = x^2 - 9
= (x - 0)^2 - 9
Vertex : (0,-9)
Axis of symmetry: x = 0
x-intercepts: x^2 = 9 -> x = ±3
Left x-intercept: (-3,0)
right x-intercept: (3,0)
Since the function is well-defined for any x-values,
we can say that its domain is the set of all real numbers.
Since the minimum point of the graph is (0,-9),
The range will be greater than or equal to -9.

the reason physical state affect the rate of a chemical rection
Answer:
Usually reactions speed up with increasing temperature. Physical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate. The presence (and concentration/physical form) of a catalyst (or inhibitor).

The cube root of a number is 2. Write an equation, using x, that represents this situation.
Answer:
x - 8 = 0
Step-by-step explanation:
Since, the cube root of a number is 2.
Let the number be x.
Therefore,
[tex] \sqrt[3]{x} = 2 \\ cubing \: both \: sides \\ {( \sqrt[3]{x})}^{3} = {(2)}^{3} \\ x = 8 \\ x - 8 = 0[/tex]

A right cone has a slant height of 6 and a radius of 4. What is its surface
area?
A. 40 units^2
B. 56 units^2
C. 24 units^2
D. 16 units^2
The surface area of the cone is 16π square units.
What is the surface area of the cone?The surface area of the cone is given by;
⇒ Area = πrl + πr²
Here, We have;
A right cone has a slant height of 6 and a radius of 2.
Substitute all the values in the formula
⇒ Area = πrl + πr²
⇒ Area = π x 2 x 6 + π x 2²
⇒ Area = 16π
Hence, The surface area of the cone is 16π square units.

Answer:
64 degrees
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relations between triangle sides and trig functions. Here, the marked sides are opposite and adjacent to the marked angle, so the relevant relation is ...
Tan = Opposite/Adjacent
tan(θ) = 29/14
To find the angle measure, we use the inverse function. It may be called tan⁻¹ on your calculator. It also goes by the name "arctangent." The term "arctan" can be thought of, or even pronounced as, "the angle whose tangent is ...".
θ = arctan(29/14) = 64.23°
The measure of angle θ is about 64°.
_____
Additional comment
The default units for angle measure are radians in most spreadsheets and on-line calculators. You need to make sure your hand-held calculator mode is set to give angles in the units you want. Here, we've given the angle in degrees, which is usually what is expected in problems like this.

6x + 9 <7x
Answer:
x > 9
Step-by-step explanation:
6x + 9 < 7x .
-6x -6x <---- Subtract 6x from both sides.
9 < x <----- 7x - 6x = 1x (which can also be written as just x)
Therefore the answer is x > 9.
