so,put x=0 to get y intercept

i.e, y =5×0 -1

i.e, y= -1

Im stuck .... What is the solution for the equation 2(3x−7)=−4(x+5)+3? plss show work

Ipatiy [6.2K]

Answer:

$2(3x - 7) = - 4(x + 5) + 3 \\ 6x - 14 = - 4x - 20 + 3 \\ 6x + 4x = - 20 + 3 + 14 \\ 10x = - 3 \\ \\ x = \frac{ - 3}{10} \\ \\ x = - 0.3$

I hope I helped you^_^

Joshua used two wood beams, PC and QA, to support the roof of a model house.

Mazyrski [523]

Answer:

$\boxed{\boxed{PQ=3.6\ in}}$

Step-by-step explanation:

As it is given as ΔQRP and ΔARC are similar, so the ratio of their corresponding sides will be same.

So,

$\dfrac{RC}{PR}=\dfrac{AC}{PQ}$

It is given as,

RC = 3.3

PR = 1.8

AC = 6.6

PQ = ??

Putting the values,

$\Rightarrow \dfrac{3.3}{1.8}=\dfrac{6.6}{PQ}$

$\Rightarrow PQ=\dfrac{6.6\times 1.8}{3.3}=3.6$

Hi there, hope everyone is well and staying cool :D

gogolik [260]

Answer:

A) By using the Pythagorean Theorem, we will see that $8^2 + 15^2 = 17^2$ . If we simplify it, we will find that the hypotenuse of Δ $ABC = 17$

B) approximately $18.79$

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is $leg^2 + leg^2 = hypotenuse^2$

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, $8^2 + 17^2 = AD$ .

$8^2 + 17^2 = 64 +289$

$64 + 289 = 385$

$\sqrt{385} \\$ ≈ $18.79$

Hope you do well on the rest of your math problems :D
