First, find 12 percent of 1,150,

12 percent of 1,150 = 138.

Now, add 1,150 + 138,

1,150 + 138 = 1,288

Answer:

y=5/2x

Step-by-step explanation:

the y intercept is (0,0) so it isn't included in the equation. now we know the middle solution isn't correct. the points we use to find slope are (-2,-5) and (2,5) which ends up being 5/2.

Answer:

GCHE

Step-by-step explanation:

Answer and Explanation:

Problem 1:

4x - 12 = 16

4x = 28

x = 28 / 4

x = 7, G

Problem 2:

5x + 10 = - 25

5x = - 35

x = - 35 / 5

x = -7, C

Problem 3:

x / 2 + 11 = 12

x / 2 = 12 - 11 = 1

x = 2 * 1

x = 2, H

Problem 4:

7.5 * x + 10 = -5

x = -2, E

(Not sure about this one)

Code: GCHE

Step-by-step explanation:

Let's solve your equation step-by-step.

4−(9g−5)=−18

Step 1: Simplify both sides of the equation.

4−(9g−5)=−18

4+−1(9g−5)=−18(Distribute the Negative Sign)

4+−1(9g)+(−1)(−5)=−18

4+−9g+5=−18

(−9g)+(4+5)=−18(Combine Like Terms)

−9g+9=−18

−9g+9=−18

Step 2: Subtract 9 from both sides.

−9g+9−9=−18−9

−9g=−27

Step 3: Divide both sides by -9.

−9g−9=−27−9

g=3

Answer:

-3/10

Step-by-step explanation:

4-5(6+4x)=-16

4-30-20x=-16

-26-20x=-16

-20x=-16+26

-20x=6

x=6/-20

x=-3/10

Answer:

x = -2

Step-by-step explanation:

4 - 5 x 2x = -16

4 - 10x = -16

10x = -20

x = -2

Answer:

[tex]x^{2} -8x+12[/tex] (that means u got it right)

Step-by-step explanation:

basically use the distributive property to multiply everything by each other.

x*x=[tex]x^{2}[/tex]

x*(-2) + x*(-6)= -8x

-6*-2=12

Put it all together and u get the original.

Sorry if this is confusing.

Answer:

B. 18

Step-by-step explanation:

[tex]x^{2} + 36x + 324 = (x + m)^{2} [/tex]

[tex](x+18)^{2}= (x + m)^{2} [/tex]

[tex]\cancel x+18= \cancel x + m[/tex]

[tex]18= m[/tex]

Answer:

15

Step-by-step explanation:

Answer:

21

Step-by-step explanation:

It is given that two lines are parallel, and hence the corresponding angles are congruent, by corresponding angles postulate. It is also given that the triangles in the photo share an angle, by the reflexive property, the shared angle is congruent. Hence one can use angle-angle to determine that the two triangles in the picture are similar.

Using this, one can set up a proportion with the sides. The ratios of any two corresponding sides are the same as any other two corresponding sides in the triangle, respectively, this is due to the corresponding parts of similar triangles theorem.

[tex]\frac{9+12}{12}=\frac{49}{49-?}[/tex]

Simplify,

[tex]\frac{21}{12}=\frac{49}{49-?}\\\\\frac{7}{4}=\frac{49}{49-x}[/tex]

Cross products,

[tex](7)(49-?) = (4)(49)\\\\343-7?=196[/tex]

Inverse operations,

[tex]343-7?=196\\-343\\\\-7? = -147\\/-7\\\\?=21[/tex]

The expression 27a^3 + 54a^2b + 36ab^2 + 8b^3​ has a cube root of 3a + 2b

From the question, the expression is given as

27a^3 + 54a^2b + 36ab^2 + 8b^3​

The above expression is the cube of the sum of two numbers or expressions

Where the numbers are

27a^3 and 8b^3​

The cube roots of 27a^3 and 8b^3​ are represented as

∛27a^3 and ∛8b^3​

Evaluate the cube roots

3a and 2b

Express as sum

3a + 2b

Hence, the cube root of the expression is 3a + 2b
