What is an equation of the line that passes through the point (-1,4) and is parallel to the line x+y=4x?
Answer:
Y= 14x+5
Step-by-step explanation:
solve for y and x explain your thinking
Answer: X=2.5, Y= 6.5
Step-by-step explanation:
It seems the triangle on the left is being transformed and a scale factor of 0.5 or 1/2 is being used since the 6 is half of 12. Therefore you divide 5 by 2 to get 2 and the 13 by 2 to get 6.5.
A line passes through the point (6,-1) and is perpendicular to the line with equation - 2x + 3y = -6.
Which is the equation of the line?
Answer: y = − 3/2 x + 8
Step-by-step explanation:
Find the Perpendicular Line
Solve −2x + 3y = −6.
y = −2 + 2x/3
Find the slope when y = −2 + 2x/3 .
m = 2/3
The equation of a perpendicular line must have a slope that is the negative reciprocal of the original slope.
[tex]m[/tex] perpendicular = [tex]-\frac{1}{\frac{2}{3} }[/tex]
Simplify to find the slope of the perpendicular line.
perpendicular = −3/2
Find the equation of the perpendicular line using the point-slope formula.
y + 1 = − 3/2
⋅ (x − 6)
Write in y = mx + b form.
y = − 3/2 x + 8
What would be the third step in simplifying the expression 3 + (9 - 5) 2 ÷ 8?
Answer:
Third step is divide 8 by 8

The net of a right rectangular prism is shown below. The measurements are given to the nearest tenth of a centimeter. What is the surface area of the prism?
Answer: c. 352.50 cm²
Step-by-step explanation:
Looking at the shape one can see that it is made up of 3 rectangles and 2 triangles.
The surface area will therefore be the sum of the areas of these 5 shapes.
Rectangle area = Length * width
= 7.5 * 13.5
= 101.25 cm²
There are 3 of them:
= 101.25 * 3
= 303.75 cm²
Triangles = 1/2 * base * height
= 1/2 * 7.5 * 6.5
= 24.375 cm ²
There are two of them:
= 24.375 * 2
= 48.75cm²
In total:
= 303.75 + 48.75
= 352.50 cm²

in the rigid class structure of the colonies, native-born Spaniards who held all the important positions in government were known as peninsulares. Those of Spanish descent born in the colonies were called creoles. Poor colonists of mixed race, Spanish and Indian, were called mestizos. At the bottom of the social structure were the indians/native peoples, who were poor and did most of the work.
i need help please?!?!?
Answer:
c=2a+b/d
Step-by-step explanation:
Multiply both sides by c.
2a+b=cd
Flip the equation.
cd=2a+b
Divide both sides by d.
cd/d = 2a+b/d

Please help :( I will mark brainliest.
Answer:
The value of x is 29.
Step-by-step explanation:
→ The angles arent congruent, they are supplementary.
→ Supplementary angles equals 180 degrees.
→ The equation looks look:
[tex]2x - 10 + 4x + 16 = 180[/tex]
→ Let's solve the equation.
[tex]2x - 10 + 4x + 16 = 180 \\ 6x + 6 = 180 \\ \frac{ \: \: \: \: \: - 6 = - 6}{ \frac{6x}{6} = \frac{174}{6} } \\ x = 29[/tex]
→ Therefore, the value of x is 29.
