Answer:
y = 2x + 5
Step-by-step explanation:
Finding the slope:
[tex]\frac{y2-y1}{x2-x1}\\[/tex]
= (1-(-3))/(-2-(-4))
= (1+3)/(-2+4)
= 4/2
= 2
Slope: 2
Substituting the slope into the formula 'y=mx+c':
y = 2x+c
Substituting any point (in this case, (-2,1)):
1 = 2(-2) + c
1 = -4 + c
c = 1 + 4
c = 5
Hence,
y = 2x + 5

Answer:it’s b
Step-by-step explanation:
The sum of the measures of two angles is 140 degrees. The ratio of their measures is 3:4.
Answer: The measurement of the first angle would be 60 degrees and the second angle would be 80 degrees.
Step-by-step explanation: They both are equal to the ratio of 3:4 because 3 x 20 would be 60 and 4 x 20 is 80. When added together they would equal is 140 degrees.
The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer:
42°Step-by-step explanation:
The sum of 3 angles in any triangle are equal to 180°
So:
1.) 57 + 81 = 138
2.) 180 - 138 = 42°
Answer: 42°
Answer:
0.05

Hello could someone solve this please? The answer is: x = -1 or x = -2/25.
I would like a step by step solution please
Answer: the answer only -2/25
Step-by-step explanation:
[tex](5x + 3)^{2}= (\sqrt{3x+7} )^{2}[/tex]
[tex]25x^{2} +30x++9 = 3x+7[/tex]
[tex]25x^{2}+27x+2=0[/tex]
[tex](x+1)(25x+2)=0[/tex]
[tex]x=-1 , -\frac{2}{25}[/tex]
Check
[tex]x=-1[/tex]
[tex]5(-1)+3 =\sqrt{3(-1)+7}[/tex]
[tex]-2 =2[/tex]
The equality is false.
[tex]x=-\frac{2}{25}[/tex]
[tex]5(-\frac{2}{25} )+3 =\sqrt{3(-\frac{2}{25} )+7}[/tex]
[tex]\frac{13}{5}= \frac{13}{5}[/tex]
The equality is true.
[tex]x\neq -1[/tex]
[tex]x=-\frac{2}{25}[/tex]

–14d + 16 = –6d + 6 + 18
d =
Answer:
–14d + 16 = –6d + 6 + 18
d = -1
Step-by-step explanation:
I used a calculator, pls let me know if im incorrect
Answer:
d = -1
Step-by-step explanation:
combine like terms
add the coefficients(numbers with variables) together and add the integers together.
-14 d + 16 = -6d + 6 + 18 ------ add 6d on both sides
-8d + 16 = 6 + 18 ---- subtract 16 on both sides
-8d = 18 - 16 + 6
-8d = 2 + 6
-8d = 8 --- divide -8 on both sides
d = -1

Answer:
6
Step-by-step explanation:
x-3 6
---- = ----
5 10
to get from 5 to 10 we multiply 5 by 2
so...
to find out what x is we need to divide 6 by 2
which is
= 3
so we know that x-3 has to be equal to 3
therefore x=6
and to check:
6-3= 3
so
3 6
-- = ----
5 10
therefore x=6

What the answer of this question?
Answer:
w = 3 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 5 and h = 6 , then
A = [tex]\frac{1}{2}[/tex] × 5 × 6 = [tex]\frac{1}{2}[/tex] × 30 = 15 cm²
Now the area of the rectangle is 15 cm²
area = length × width , that is
5w = 15 ( divide both sides by 5 )
w = 3 cm
Answer:
2.5
Step-by-step explanation:
equation the two areas in an equation and they are equal
[tex] \frac{1}{2} base \times height = length \times \: width[/tex]
but the width is w
substituting the values,
[tex] \frac{1}{2} (6)(5) = 6 \times w \\ 15 = 6w \\ w = \frac{15}{6 =} = \frac{5}{2 } = 2.5[/tex]

A pharmacy claims that the average medication costs $32, but it could differ by as much as $8. Write an absolute value inequality to determine the range of medication costs at this pharmacy.
a
|x − 32| ≥ 8
b
|x − 8| ≥ 32
c
|x − 32| ≤ 8
d
|x − 8| ≤ 32
Step-by-step explanation:
So,
We can tell that the most expensive medication costs $40 and the cheapest costs $24. Thus, only options A and C are left.
To see which inequality is true, test a value, such as $30, in the equation in option C.
|30 - 32| ≤ 8
|-2| ≤ 8
2 ≤ 8
Option C is correct.

A solid has faces that consist of 4 triangles, 3 rectangles, and 1 hexagon. The solid has 9 vertices. How many edges does the solid have?
A 12 edges
B. 15 edges
C 18 edges
D 21 edges
Answer:
Step-by-step explanation:
c)18
Answer:
B. 15 edgesStep-by-step explanation:
According to Euler's formula:
F + V = E + 2, where F- faces, V- vertices, E- edgesSubstitute known values and solve for E:
(4 + 3 + 1) + 9 = E + 217 = E + 2E = 17 - 2E = 15Correct choice is B
