Answer:
[tex]\rm x=7[/tex]
Step-by-step explanation:
Given equation:
[tex]\rm 5x-2+x=9+3x+10[/tex]
Collect like terms:
[tex]\implies \rm 5x+x-2=3x+10+9[/tex]
Combine like terms:
[tex]\implies \rm 6x-2=3x+19[/tex]
Add 2 to both sides:
[tex]\rm \implies 6x-2+2=3x+19+2[/tex]
[tex]\rm \implies 6x=3x+21[/tex]
Subtract 3x from both sides:
[tex]\rm \implies 6x-3x=3x+21-3x[/tex]
[tex]\implies \rm 3x=21[/tex]
Divide both sides by 3:
[tex]\implies \rm 3x \div 3=21 \div 3[/tex]
[tex]\implies \rm x=7[/tex]

Which is the equation of the line that passes through the point (2, -2) and has a slope of 3? A. y = 3x - 2 B. y = 3x - 8 C. y = 2x + 3 D. y = - 2x + 2
Answers
Answer:
y = m x + b standard equation for straight line
-2 = 3 *2 + b to satisfy above equation
b = -8
therefore
y = 3 x - 8
if x = 2 then y = -2
I purchased a piece of meat from the supermarket and the instructions on the
packaging said I should cook the meat for 20 minutes for each 550grams of weight.
The meat weight written on the outside of the packaging was 0.733kg. How long will
it take to cook the meat if I follow the instructions?
Answers
The time it would take to cook the meat if I follow the instruction is 26.65 minutes.
How long would it take to cook the meat?
The first step is to determine how long it would take to cook 1 gram of meat.
20 / 550 = 0.0364 minutes
Now convert kg to gram
0.733 x 1000 - 733 grams
Multiply, the answer gotten in the first step by 733
0.0364 x 733 = 26.65 grams

An ingot of metal shaped like the triangular prism below has a total mass of

Answers
Answer:
453
Step-by-step explanation:
9514 1404 393
Answer:
20 g/cm³
Step-by-step explanation:
The volume of the prism is the product of the area of its triangular base and its height. The triangle area is ...
A = 1/2bh
A = 1/2(16 cm)(8 cm) = 64 cm²
The height of the prism is 20 cm, so its volume is ...
V = Bh = (64 cm²)(20 cm) = 1280 cm³
The density of the ingot is the ratio of its mass to its volume.
ρ = M/V = (25,600 g)/(1280 cm³) = 20 g/cm³
The density of the ingot is 20 g/cm³.

Classify the graph as a linear function, nonlinear function, or relation (non-
function).
A. Linear function
B. Nonlinear function
C. Relation
Answers
Answer:
The answer is C my friendThe given graph is represents a relation, Option C is correct.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The graph is classified as a relation (non-function).
A relation is any set of ordered pairs, and a function is a special type of relation where each input (x-value) corresponds to exactly one output (y-value).
In other words, for a function, there are no repeated x-values with different y-values.
Linear Function Graph has a straight line so the graph is not linear function.
A nonlinear function is a function whose graph is not a straight line.
Its graph can be any curve other than a straight line.
Hence, the given graph is represents a relation, Option C is correct.

Answer:
Angle B is 52 degrees
Step-by-step explanation:
The outer angle 112 adds up with the inner angle to make 180. So angle C is 68. All the angles should add up to 180, so add them all together.
68+4y+3y+7 = 180
75+7y = 180
7y = 105
y = 15
To double-check this, plug 15 into y and add up all the angles, it should add up to 180.
3(15)+7 = 52
4(15) = 60
68+60+52 = 180
