sub x = 3
f(3) = 3( 3 ) + 2
=9 + 2
=11
Answer:
f(3) = 11
Step-by-step explanation:
To evaluate f(3) substitute x = 3 into f(x) , that is
f(3) = 3(3) + 2 = 9 + 2 = 11

Shanice spent half of her weekly allowance on cloths. To earn more money her parents let her clean the gutters for $7. What is her weekly allowance if she ended with $14?
Answer:
$14
Step-by-step explanation:
After Shanice spent half of her allowance and earned $7, she is left with $14.
This means the remaining of her weekly allowance is $7, This can be derived by subtracting $7 from 15 - $14 - $7 = $7
This means that it is $7 that remains after spending half of her weekly allowance
her weekly allowance = $7 x 2 = $14

Based on the figure, select all true equations.
A. cos (42) = b/c
B. cos (48) = b/c
C. sin (42) = b/c
D. sin (48) = b/c
E. tan (42) = b/a
F. tan 48 = a/b
Answer:
f I think
Step-by-step explanation:
A/B has 48 C would be 90 but I doesn't have that
The true equations are given below and this can be determined by using the sum of interior angle properties and the trigonometric functions.
Given :
A triangle ABC is given. Angle A = 48 degrees.The following steps can be used in order to determine the true equations:
Step 1 - First, determine the measure of angle B by using the sum of interior angle property.
[tex]\rm \angle A + \angle B + \angle C = 180^\circ[/tex]
48 + 90 + [tex]\rm \angle B[/tex] = 180
[tex]\rm \angle B[/tex] = 42 degrees
Step 2 - Now, the trigonometric functions can be used in order to determine the true equations.
Step 3 - The expression of the sine function is given below:
[tex]\rm sin42 = \dfrac{b}{c}[/tex]
Step 4 - The expression of the cosine function is given below:
[tex]\rm cos48 = \dfrac{b}{c}[/tex]
Step 5 - The expression of the tangent function is given below:
[tex]\rm tan42 = \dfrac{b}{a}[/tex]
[tex]\rm tan48 = \dfrac{a}{b}[/tex]
Therefore, the true equations are given by options B), C), E), and F).

11. If g(x) = 3x² + 8 were shifted 5 units to
the right and 2 units down, what would
be the new equation, h(x)?
| h(x) =
Answer:
h(x) = 3(x - 5)^2 + 6.
Step-by-step explanation:
g(x) = 3x^2 + 8
Shifting 5 units to the right gives:
3(x - 5)^2 + 8
Now 2 units down :
3(x - 5)^2 + 8 - 2
= 3(x - 5)^2 + 6.

I need help finding the rate of change can someone help me
Answer:
rate of change is 4.
Step-by-step explanation:
rate of change is the slope, so, pick any two relations given to us in the table.
(-3, -14) and (-1, -6).
slope = y2 - y1/ x2 - x1
slope = -6 - (-14)/-1-(-3)
slope = 8/2 = 4.
the rate of change is 4.

The length of a triangle is eight more than twice its width. The perimeter is 88 feet. Find the dimensions of the rectangle.
Answer:
Length = 32 feet
Width = 12 feet
Step-by-step explanation:
From the question;
Width = w
Length = 2w + 8
But the perimeter of a rectangle = 2(l + b)
perimeter = 88 feet
88 = 2(2w + 8 + w)
88 = 2(3w + 8)
88 = 6w + 16
88 - 16 = 6w
72 = 6w
w = 72/6
w = 12 feet
Hence;
Length = 2(12) + 8 = 32 feet
Dimensions of the rectangle is;
Length = 32 feet
Width = 12 feet

Find the length of side x in the simplest radical form with a rational denominator.
find the side length
Answer:
area of square=side²
36/49yd²=side²
(36/49yd²)²=side
6/7 yd=side
Answer:
s = [tex]\frac{6}{7}[/tex] yd
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the length of side )
Given A = [tex]\frac{36}{49}[/tex] , then
s² = [tex]\frac{36}{49}[/tex] ( take the square root of both sides )
s = [tex]\sqrt{\frac{36}{49} }[/tex] = [tex]\frac{\sqrt{36} }{\sqrt{49} }[/tex] = [tex]\frac{6}{7}[/tex]

Answer:
b
Step-by-step explanation:
b is the only right answer since 4/2 is just equal to 2
1.5 rounded is 2 since its anything above .4
6/2 would equal 3 which is way over
2/4 isnt even a whole

WILL GIVE BRAINLIEST!!!!!!! find the value of x. find the value of y.
Answer: x=20 y=20√2
Since this is a 45-90-45 right triangle, so sides are going to be the same. To solve for y, you have to use Pythagorean theorem. (a^2+b^2=c^2) So put in the a and b values, in this case, it's 20 and 20. (20^2+20^2=c^2) Then you can solve the exponents, (400+400=c^2) add them up (800=c^2), then square root everything which gives you y=20√2 or 28.28(rounded)
