Answer:
∠B = 52°.
Step-by-step explanation:
Given: m∠A=(8x-4)° and m∠B=(7x+3)°. ∠A and ∠B are vertical angles.
Since ∠A and ∠B are vertical angles. So, there measure are equal.
[tex]m\angle A=m\angle B[/tex]
[tex](8x-4)^{\circ}=(7x+3)^{\circ}[/tex]
[tex]8x-4=7x+3[/tex]
[tex]8x-7x=4+3[/tex]
[tex]x=7[/tex]
Now,
[tex]m\angle B=(7(7)+3)^{\circ}[/tex]
[tex]m\angle B=(49+3)^{\circ}[/tex]
[tex]m\angle B=52^{\circ}[/tex]
Therefore, the measure of ∠B is 52°.
f(x) = -x + 4 and g(x) = 6x + 3, find (f(x) - g(x))
A. -5x-1
B. 5x +1
C. -7x +1
Answer:
C
Step-by-step explanation:
f(x) - g(x)
= - x + 4 - (6x + 3)
= - x + 4 - 6x - 3 ← collect like terms
= - 7x + 1 → C

Given: -7(x+2)+4x=6(2x-4); Prove x=2/3
Answer:
see below
Step-by-step explanation:
-7(x+2)+4x=6(2x-4)
Distribute
-7x -14 +4x = 12x -24
Combine like terms
-3x-14 = 12x-24
Add 3x to each side
-3x-14+3x = 12x-24+3x
-14 = 15x-24
Add 24 to each side
-14+24 = 15x -24+24
10 = 15x
Divide each side by 15

Answer:
So the value of s = 7 cm
Step-by-step explanation:
We know that, Area of a triangle = 1/2 * b * h
So, base = 24 cm
height = s
Area = 1/2 * b * h
=>84 = 1/2 * 24 * h
=>84 = 12 * h
=>84 / 12 = h
=> 7 = h (in cm)

[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
You can combine the two red shaded areas to get a larger portion with an angle of 120°.
The total degrees in a circle is 360° and since [tex]\frac{120}{360} =\frac{1}{3}[/tex],
The area of the combined red shaded area is [tex]\frac{1}{3}[/tex] of the entire area of the circle.
Thus, the probability of choosing the red shaded area is [tex]\frac{1}{3}[/tex]

Which of the Following is the solution to 4|x+3| greater than equal to 8? Options are as followed: A.x less then equal to -5 or x greater than equal to -1 B. x greater than equal to -1 C.x less then equal to -5 and x greater than equal to -1 D. x greater then equal to -5 and x greater then equal to -1
Answer:
A
Step-by-step explanation:
4|x+3| >= 8
Divide both sides by 4
4|x+3| / 4 >= 8/4
|x+3| >= 2
Rewritten as
-2 >= x + 3 >= 2
Subtract 3 from all sides
-2 - 3 >= x + 3 - 3 >= 2 - 3
-5 >= x >= -1
Or
-1 <= x <= -5
x less then equal to -5 or x greater than equal to -1

Answer:
different variables represent unknown numbers.
Step-by-step explanation:
For example the equation 5x = 15
X is a variable that represents an unknown number. To get the unknown number in the example you need to divide 15 by 5 and 5 by 5 to get X alone and then X will equal 3.

what is 149,597,870 in scientific notation
Answer:
1.4959787 × 10^8
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10^b.
Follow the steps below to see how 149,597,870 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 149,597,870
New Number: 1.49597870
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 4 9 5 9 7 8 7 0
Decimal Count: 1 2 3 4 5 6 7 8
There are 8 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10^b
a = 1.4959787 (Please notice any zeroes on the end have been removed)
b = 8
Now the whole thing:
1.4959787 x 10^8
Step 4
Check your work:
10^8 = 100,000,000 x 1.4959787 = 149,597,870

PLSSS HELP!! For the given ordered pairs, write a function rule relating x and y. (1,4), (2,9), (3,16), (4,25)

Step-by-step explanation:
we have the following
[tex]x=1;y=4\\\\x=2;y=9\\\\x=3;y=16\\\\x=4;y=25[/tex]
the values of y are squares so we can write
[tex]x=1;y=2^{2} \\\\x=2;y=3^2\\\\x=3;y=4^2\\\\x=4;y=5^2[/tex]
