Answer:

no real solutions

Step-by-step explanation:

The discriminant is

b^2 -4ac

Where ax^ +bx+c

x^2-3x+4

so a=1 b = -3 c=4

(-3)^2 -4(1)(4)

9 - 16

-7

Since the discriminant is less than 0 there are no real solutions

×WILL MARK AS BRAINLIEST×<br>Solve the equation for b, d and x

Lera25 [3.4K]

Solve for d:
(3 (a + x))/b = 2 d - 3 c
(3 (a + x))/b = 2 d - 3 c is equivalent to 2 d - 3 c = (3 (a + x))/b:
2 d - 3 c = (3 (a + x))/b
Add 3 c to both sides:
2 d = 3 c + (3 (a + x))/b
Divide both sides by 2:
Answer: d = (3 c)/2 + (3 (a + x))/(2 b)

-----------------------------

Solve for x:
(3 (a + x))/b = 2 d - 3 c
Multiply both sides by b/3:
a + x = (2 b d)/3 - b c
Subtract a from both sides:
Answer: x = (2 b d)/3 + (-a - b c)

____________________________

Solve for b:
(3 (a + x))/b = 2 d - 3 c
Take the reciprocal of both sides:
b/(3 (a + x)) = 1/(2 d - 3 c)
Multiply both sides by 3 (a + x):
Answer: b = (3 (a + x))/(2 d - 3 c)

Answer:

x=14.4

Step-by-step explanation:

x= $\sqrt{h^2-a^2} \\$

x= $\sqrt{28^2-24^2}$

x= $\sqrt{784-576}$

x= $\sqrt{208}$

x=14.4

A store has a 25\%25% off sale on coats. With this discount, the price of one coat is \$34.50$34.50. What is the original price

timama [110]

Answer:

$46

Step-by-step explanation:

A percent is a portion of 100. If we receive 25% off then we pay 75% of the price. 100%-25%=75%. $34.50 is 75% of the original price. We find the new price through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities. For example, we will compare percent over percent to an equal ratio of $ to $.

$\frac{75}{100} =\frac{34.50}{y}$
