Step-by-step explanation:
Let's solve your equation step-by-step.
−5(x+4)=70
Step 1: Simplify both sides of the equation.
−5(x+4)=70
(−5)(x)+(−5)(4)=70(Distribute)
−5x+−20=70
−5x−20=70
Step 2: Add 20 to both sides.
−5x−20+20=70+20
−5x=90
Step 3: Divide both sides by -5.
−5x
−5
=
90
−5
x=−18
Answer:
There is only one solution and the solution is (0,4).
Step-by-step explanation:
The given system has equations;

and

We equate the two equations to determine their point of intersection;




We put x=0 into the first equation to get;

There is only one solution and the solution is (0,4).
Answer:
36
Step-by-step explanation:
What function uses the ADJACENT and the OPPOSITE?
\text{SOH-CAH-TOA}
SOH-CAH-TOA
\tan F = \frac{\text{opposite}}{\text{adjacent}}=\frac{3.5}{4.8}
tanF=
adjacent
opposite
=
4.8
3.5
\tan F = \frac{3.5}{4.8}
tanF=
4.8
3.5
F=\tan^{-1}(\frac{3.5}{4.8})
F=tan
−1
(
4.8
3.5
)
F=36.098\approx 36^{\circ}
F=36.098≈36
∘
-8r on both sides; -2r=16; now divide by -2; r=-8
