What is the solution to the inequality -3x - 42 > 3?
A. X > -13
B. x < -13
C. X > -15
D. X< -15
Answer:
D. x<-15
Step-by-step explanation:
-3x-42>3 Add 42 to both sides.
+42 +42
-3x>45 Divide both sides by -3.
/-3 /-3
x>-15 Each time you multiply or divide by a negative, you flip the sign.
x<-15

Your teacher is giving you a test tomorrow with 2- and 4-point questions for a total of 100 points. The number of 4 points questions is one-third the number of 2-point questions. How many 2- and 4-point questions are on the test?
Answer:
25 4-point questions and 75 2-point questions
Step-by-step explanation:
Let x = no. of 4-point questions
Then 3x = no. of 2-point questions
So, x + 3x = 100
4x = 100
x = 25 = no. of 4-point questions
and 3x = 3(25) = 75 = no. of 2-point questions
Mariah worked for 3 hours and earned a total of $28.50. Which equation can be used to find , the amount of money Mariah earns per hour?
A. r = 28.5 - 3
B. R=28.5 · 3
C. r=28.5 ÷ 3
D. r = 28.5 + 3
Answer:
C. r = 28.50 ÷ 3
Step-by-step explanation:
You have to divide to see the rate
Given:
[tex]\to \text{time}= 3 \ hours\\\\\to \text{total eran}= \$28.50 \\\\[/tex]
To find:
earn per hour=?
Solution:
[tex]\to \text{time}= 3 \ hours\\\\\to \text{total eran}= \$28.50 \\\\[/tex]
calculate earn per hour:
[tex]= \frac{\text{total earn }}{ \text{time}}\\\\= \frac{28.50}{3}\\\\= \$ 9.5\\\\[/tex]
Therefore, the answer is "$9.5".

42 = y + 15 whats y? y == __
Solution
[tex]y=27[/tex]
Step-by-step explanation:
Subtract [tex]15[/tex] from both sides of the equation:
[tex]42=y+15[/tex]
[tex]42[/tex][tex]-15=y+15[/tex][tex]-15[/tex]
Simplify:
Subtract the numbers:[tex]42-15=y+15-15[/tex]
[tex]27=y+15-15[/tex]
Subtract the numbers:[tex]27=y+15[/tex][tex]-15[/tex]
[tex]27=y[/tex]

If the measure of ZDEF is 65°, what is the measure of DE?
A. 115°
65
B. 65°
C. 130°
D. 32.5°
Answer:
I believe it is C because i heard of that one before
The measure of DE is 130 degrees if the measure of DEF is 65 in the circle option (A) is correct.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Circle is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have:
The measure of DEF = 65 degrees
C is the center.
Angle CED = 90 - 65 = 25 degrees
Angle DCE = 180 - 25 - 25
Measure of DE = 130 degrees
Thus, the measure of DE is 130 degrees if the measure of DEF is 65 option (A) is correct.

1. g(x) = f(x) - 7
how do u solve these?
Answer:
g' (×)=f
Step-by-step explanation:
g (×)=f×-7
g' (×)= d÷d× (f×-7)
d÷d×(f+g)=d÷d×(f)+d÷d=(g)
g' (×)=d÷d×(f×)-d÷d×(7)
g'(×)=f-d÷d×(7)
g'(×)=f-0
g'(×)=f

Answer:
13cm
Step-by-step explanation:
The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.
a = 12cm
b = 5cm
c = hypotenuse
[tex]12^{2} +5^{2} =c^{2}[/tex]
[tex]144+25=c^{2}[/tex]
[tex]\sqrt{169} =c[/tex]
13 = c
Answer:
13
Step-by-step explanation:
a^2+b^2=c^2
12^2+5^2=c^2
144+25=c^2
169
square root of 169=13
13=c

the width of a rectangle is half of the length of the rectangle. if the perimeter is 84 inches what is the length of the rectangle?
Answer:
The length of the rectangle is 28 inches.
Step-by-step explanation:
We have that the width (W) of a rectangle is half of the length (L) of the rectangle:
[tex] W = \frac{1}{2}L [/tex] (1)
Also, the perimeter is 84 inches:
[tex] P = 2W + 2L = 84 in [/tex] (2)
By entering equation (1) into equation (2) we have:
[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]
[tex] L = \frac{84}{3} = 28 in [/tex]
Therefore, the length of the rectangle is 28 inches.

What is the relationship between sin x and cos y?
Answer:
It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis. Notice also that the graphs are exactly the same shape but horizontally shifted /2 units. They are related by: sin (x) = cos (x - /2) and cos (x) = sin (x + /2).
