Hello could someone solve this please? The answer is: x = -1 or x = -2/25.
I would like a step by step solution please
Answers
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]

What the answer of this question?
Answers
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]

How long would it take for a deposit to double if the annual interest rate is 5%?
Show your work
Answers
Given-
Annual interest rate = 5%
By using the rule of 72,
Rate x Time = 72
Rate = 5%
t = ?
So,
5 x t = 72
5t = 72
Isolate t by dividing both sides by 5 :-
→ 5t/5 = 72/5
→ t = 14.4 years
Hence, it will take 14.4 years for the deposit to double at 5% annual rate.

write the equation of the line in slope intercept form if its slope is 3 and y intercept is -5
If you answer correctly I will give brainliest.
Answers
Answer:
y = 3x - 5
Step-by-step explanation:
1. The slope-intercept form a line is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.
2. Given the values of m and b, let's plug them in:
[tex]y = (3)x+(-5)[/tex] [tex]y = 3x-5[/tex]Therefore, the equation of the line in slope-intercept form is y = 3x - 5.
Have a lovely rest of your day/night.
The equation of the line in slope intercept form is y=3x-5.
Given that, slope is 3 and y intercept is -5.
What is the slope intercept form?The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as: y = mx + b.
Put m=3 and b=-5 in y = mx + b and simplify.
That is, y=3x-5
Therefore, the equation of the line in slope intercept form is y=3x-5.
