Which values of x satisfy the inequality 0.5x - 0.75 _> 3.25?
a x_>5
b x_<5
c ×_<8
d ×_>8
0.5x - 0.75 _> 3.25
Add 0.75 to both sides:
0.5x _> 4
Divide both sides by 0.5:
x _> 4/0.5
x_> 8
The answer is d.
If f(x)=2x(With an exponent of 2) -3, find f(-2)
[tex]f\left(x\right)=2x^2-3f ( x ) = 2 x 2 − 3 find f\left(-2\right)f ( − 2 ).[/tex]
Answer:
5
Step-by-step explanation:
Put -2 where x is and do the arithmetic.
f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
f(-2) = 5
Answer:
f(-2) = 5
Step-by-step explanation:
We just need to substitute x with -2 and simplify.
f(x) = 2x² - 3
f(-2) = 2(-2)² - 3
f(-2) = 2(4) - 3
f(-2) = 8 - 3
f(-2) = 5

You live 6 miles from school. if you start walking from school at 3:00, and your best friend starts skateboarding from school towards youe home at the same time, what time will you meet and how far from your home? your speed is 3.5 miles/hour, and your friends speed is 6 miles/hour
Answer: 2 hrs 40 min
Step-by-step explanation: Ok I might be wrong so try to do other people's answers instead of mine.
So your friend is going 6 miles per hour, so he/she will be there in an hour
But you are going 3.5 miles an hour.
So what I did was divide 3.5 by 5 and 60 by 5 and found out that you are going 0.5 miles every 20 min. Then I added up the distance and time and got 6 miles every 2 hrs and 40 min
REMINDER: I might be wrong because I haven't done this question before, but tell me if I'm right or not! :D

Answer: 123
Step-by-step explanation:
60+63=123
180-123=57
180-57=123
Answer:
123°
Step-by-step explanation:
Subtract the measures of the given interior angles from 180 to find the measure of the missing interior angle
180 - 60 - 63 = 57°
Subtract 57 from 180 to find the measure of the external angle/angle 1.
180 - 57 = 123°

For each menu item at a fast food restaurant, the fat content (in grams) and the
number of calories were recorded. A scatterplot of these data is given:
Sparta
The restaurant decides to add six new high-calorie, low-fat pasta dishes to its menu.
What is a plausible value for the new correlation coefficient describing the
relationship between fat and calories?
Oa) 0.7
Ob) 10.7
C) 0.2
d) 0.2
Answer:
The answer is "Option a".
Step-by-step explanation:
please find the attached file.
In the given question, the positive correlation shows the scatterplot and, by adding six now higher calories, low-fat pasta, is the positive value for the new correlation of the coefficient will be decreasing.
In this question, the points are more close to the line and increasing from left to right, which can be mostly like, that's why the choice "a" is correct.

Problem 1
Answer: Choice B) angle1 = 26, angle2 = 64----------
Explanation:
Complementary angles add to 90
(angle1)+(angle2) = 90
(5x+6)+(68-x) = 90
4x+74 = 90
4x = 90-74
4x = 16
x = 16/4
x = 4
So,
angle1 = 5x+6 = 5(4)+6 = 26
angle2 = 68-x = 68-4 = 64
Note how
angle1+angle2 = 26+64 = 90

==========================================
Problem 2
Answer: Choice D) BC, AC, AB----------
Explanation:
The shortest side of a triangle is always opposite the smallest angle.
The longest side of a triangle is always opposite the largest angle.
Based on those two facts, we can say the shortest side is BC (since angle A = 53 is the smallest angle) and the longest side is AB (since angle C = 70 is the largest)
The order from smallest to largest is
BC, AC, AB
==========================================
Problem 3
Answer: Choice D) B < C < A----------
Explanation:
Use the reverse of the idea from problem 2. We know that AC is the smallest side which must mean that angle B is the smallest angle. Since BC is the largest side, angle A must be the largest angle.
The order of the angles is B < C < A
==========================================
Problem 4
Answer: Choice A) angle 5 = 50, angle 8 = 130----------
Explanation:
The same side exterior angles must be supplementary to have parallel lines.
==========================================
Problem 5
Answer: Choice A) angle G is the smallest----------
Explanation:
Use the same idea as problem 2. The smallest angle is opposite the smallest side. The smallest side is 48, so angle G being opposite of that side, is the smallest angle.
Angle O would be the largest as it is opposite the largest side DG = 70

How many quarts, rounded to the nearest tenth, are in 50 liters?
Answer: 52.9 quarts
Step-by-step explanation:
From the question, we are informed to calculate the number of quarts that are in 50 liters.
1 liter = 1.057 liquid quarts
50 liters will now be:
= 50 × 1.057
= 52.85
= 52.9 quarts
There are 52.8 quarts rounded to the nearest tenth
In order to get the number of quarts in 50 litres, we will use the following conversion:
1 litres = 1.05669 quartz
For 50 litres;
50 litres = x
Divide both expressions
[tex]\frac{1}{50} = \frac{1.05669}{x} \\Cross \ multiply\\x = 50 \times 1.05669\\x = 52.8345[/tex]
This shows that there are 52.8 quarts rounded to the nearest tenth
