Answer the following question from the picture:​

Answer:

Standard form:

2x + 4 = 0

Factorization:

2(x + 2) = 0

Solutions:

x = −4 /2  = −2

Answer:

x = -2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x+5−(5x+8)=−4x−7

3x+5+−1(5x+8)=−4x−7(Distribute the Negative Sign)

3x+5+−1(5x)+(−1)(8)=−4x−7

3x+5+−5x+−8=−4x−7

3x+5+−5x+−8=−4x+−7

(3x+−5x)+(5+−8)=−4x−7(Combine Like Terms)

−2x+−3=−4x−7

−2x−3=−4x−7

Step 2: Add 4x to both sides.

−2x−3+4x=−4x−7+4x

2x−3=−7

Step 3: Add 3 to both sides.

2x−3+3=−7+3

2x=−4

Step 4: Divide both sides by 2.

Answer:

x < -2

x > 6

Step-by-step explanation:

use a number line if u need a visual

Answer:6. -6 is the answer

Step-by-step explanation:add 10 to -10 and -40 and bring down 5x since -10 and 10 cancel out you have to cross it out and have -30 from -40 +10 and now 5x=-30 you have to divide 5 on each side and that would give you -6

If so, you can insert that y = -12 and solve for a which will equate to x.

[tex]-12=x^2-7x[/tex]

[tex]x^2-7x+12=0[/tex]

[tex](x-3)(x-4)=0\implies a_1=3,a_2=4[/tex]

So a could be 3 or 4 (has two solutions).

Hope this helps.

Step-by-step explanation:

Top values are domain and bottom values are Range

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Total point = 867

Let :

number of 3 point goals = p

Number of 2 point goals = 2p - 66

Number of 1 point goals = (2p - 66) - 36 = 2p - 102

Hence,

3p + 2(2p - 66) + 2p - 102 = 867

3p + 4p - 132 + 2p - 102 = 867

3p + 4p + 2p - 234 = 867

9p - 234 = 867

9p = 867 + 234

9p = 1101

p = 122.33

2 pointer = 2p - 66

2(122.33) - 66 = 178.67

1 point = 2p - 102

2(122.33) - 102

= 142.67

Note: you may need to recheck the parameters given, because the expected result should be whole numbers

Answer:

Step-by-step explanation:

Gary saved dimes and nickels at a ratio of 5:7.

5/12 = Dimes

7/12 = Nickels

Then, he saved 20% more dimes and 3 times the number of nickels.

If he had 540 dimes and nickels altogether in the end, how many more nickels then dimes did he have?

Let the number of dimes = x

Let the number of nickels = y

Total number of dimes and nickels = 540

Answer:

I believe it is a good representation because it shows the differences in the heights to the weights.

Answer:

No, I don't believe this is the most appropriate format, the scatter plot is good but the weight section is not labeled correctly, the dollar signs don't belong, they are irrelevant to weight and height. And the height section should be changed to feet instead of inches, it would just make more sense.

Answer:

[tex]y=-5(x-4)^2+4[/tex]

Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y=a(x-h)^2+k[/tex]

Where (h, k) is the vertex of the parabola, and a is a coefficient different from zero.

The vertex is located at (4,4).

Substituting the coordinates of the vertex, the equation of the function is:

[tex]y=a(x-4)^2+4[/tex]

The value of a will be determined by using the given point (3,-1).

[tex]-1=a(3-4)^2+4[/tex]

Operating:

[tex]-1=a(1)+4[/tex]

Solving:

[tex]a=-5[/tex]

The equation of the graph is:

[tex]\boxed{y=-5(x-4)^2+4}[/tex]

Answer:

They made a $531 commission.

Step-by-step explanation:

The given is:

We need the value of the commission

Let us find the commission of every TV, then find the total amount of all

∵ The price of each TV is $885

∵ The commission is 18 %

→ Find 18% of $885

∴ The commission on every TV = 885 × 15%

∴ The commission on every TV = 885 × 15/100

∴ The commission on every TV = $132.75

∵ The salesperson sold 4 TV

∴ The commission on them = 4 × 132.75

∴ The commission on them = $531

They made a $531 commission.

Answer: $637.20

Step-by-step explanation:

Each TV is $885

do 885 · 18% or 885 · 18/100

that is 159.3

multiply that by the amount of TVs sold (4)

159.3 · 4 = 637.2

$637.20

Answer:

3-2x=15

Step-by-step explanation:

add 3 to both sides makes -2x=18. divide -2 from both side gets the answer x=-9, so the answer is C, -9

b - the other base;

A = 9/2 ( b + 35 )   / * 2  ( we will multiply both sides of the equation by 2 )

2 A = 9 ( b + 35 )

b + 35 = 2 A / 9  

b + 35 - 35 = 2 A / 9 - 35

b = (2 A / 9 ) - 35

Answer: B ) b = 2 multiplied by A over 9 - 35

Hope this helps pls give me brainliest

Answer:

B = 2 multiplied by A over 9 - 35

Step-by-step explanation:

ion know

add 1 to both sides then divide by 3. the answer should be r=3

Answer:

r=3

Step-by-step explanation:

First, you would add 1 to both sides so:8+1=3r-1+1 so that gives you 9=3r.

Then, you divide 3 from both sides. 9/3=3r/3 so that gives you r=3

Answer:

Answer:

A

Step-by-step explanation:

d(t)=3t+1 but d(t)=7

distance*time=3*time+1

so d(t)=7 is the same as

d(t)=3(2)+1

meaning that you hiked for 2 hours.
