Pls help with question 7

Answer:

x2+6x+9=0

x^2+3x+3x+9=0

x(x+3)+3(x+3)=0

x=-3 twice

Answers:

x=4 and y=27

x=8 and y=-1

x=1 and y=216

Step-by-step explanation:

You have to plug all of the choices given into the equation until it equals to 7

∛12 + 3 = 2.9 +3 = 5.29

∛27 + 4= 3 + 4 = 7

∛16 + 3 = 2.5 +3 = 5.5

∛-1 + 8 = -1 + 8= 7

∛216 + 1 = 6 + 1= 7

∛30 - 3 = 3.11 - 3 = 0.11

∛3 + 4 = 1.44 + 4= 5.44

Answer:

Step-by-step explanation:

you can use desmos for a quick answer or

use y=mx+b where b is the y-intercept and m is the slope

the y-intercept is where the line intercepts the y axis

the slope is the rate of change of the line

for slope we use rise/run, the numerator being up and denominator being to the right.

the slope is 3, which can be written as 3/1

from the point (0,-4) which is out y-intercept, we go up 3 and to the right 1

Answer:

Richel could earn $ 85 if she works 10 hours

Step-by-step explanation:

As given

Richel earns in 4 hours = $34

By unitary method

Richel earns in 1 hour =  34/4

Richel earns in 10 hours=   34/4 x 10 =340/4 = 85$

Hence, Richel could earn $ 85

Answer:

3.5

Step-by-step explanation:

Answer:

a = 195 m , b = 180 m , c = 75 m  

Step-by-step explanation:

Let "a,b and c" be the sides of the triangle in the ration - 13:12:5

therefore , a:b:c = 13:12:5 => a = 13x , b = 12x , and c = 5x

therefore , Perimeter = 13x + 12x + 5x = 450

=> 30x = 450

=> x = 15

therefore , a = 13 x 15

b = 12 x 15 and

c = 5 x 15

hence , a = 195 m , b = 160 m and c = 75 m

Answer:

H = 43

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

f(1)=7(1-1)+8

f(1)=7(0)+8

f(1)=0+8

f(1)=8

The value of f(1) if f(x)=7(x-1)+8 is 8

From the question,

The given function is f(x)=7(x-1)+8

We are to determine the value of f(1) if f(x)=7(x-1)+8

To do this, we will put the value x =1 into the function

That is,

f(x)=7(x-1)+8 becomes

f(1)=7(1-1)+8

The, we get

f(1) = 7(0) + 8

f(1) = 7×0 + 8

f(1) = 0 + 8

∴ f(1) = 8

Hence, the value of f(1) if f(x)=7(x-1)+8 is 8

The domain of the graph is,

⇒ 2 ≤ x ≤ 5

Line segment is the part of line which have two endpoint and bounded by two distinct end points and it contain every point on the line which is between its endpoint.

Given that;

The graph is shown in figure.

We know that;

The domain of the graph is the value of x where the graph is defined.

Hence, By the graph;

The domain of the graph is,

⇒ 2 ≤ x ≤ 5

Because at 2 and 5 the closed circle is defined.
